In other words, regardless of the positional relationship or how the video camera device and the user hold the camera, the user can check the captured image of the subject in the angle or zoom state of the video camera device. Remove the positional restrictions.
Also, editing is possible using the display means of the headset device. In other words, the playback video can be displayed on the display means, and an operation using a so-called GUI (GRAPHICAL USER INTERFACE) is enabled to cope with a complicated editing operation. The commander device is used as a mouse for this operation. This is realized by providing movement sensor means in the commander device, detecting the displacement of the commander device, and transmitting the information to the video camera device. That is, pointer control corresponding to a mouse pointer is performed based on the displacement information. By detecting a specific command operation together with this pointer control, an operation corresponding to mouse click, drag, or the like is realized.

For example, it is optimal when the video camera device is fixed at a certain point and the user performs an interview or the like away from the video camera device.

  In the edit mode, the displacement information and the specific command information are set as valid information in the transmission information of the commander device, and a display video signal serving as an editing screen is generated using the reproduced imaging signal and a predetermined character video. At the same time, by performing the display operation and the corresponding process on the display means according to the received displacement information and enter information, a complicated editing operation by the GUI becomes possible. By providing such an editing function in the imaging system of the present invention with high mobility, editing immediately after coverage is possible, and use as a mobile studio is also possible.

  In addition, when the operation mode is the recording mode, the command information generated in response to the operation of a specific operator is determined as a marking command for the captured image signal recorded on the recording medium by the recording / reproducing means, and the operation mode If it is in standby mode or edit mode, it can be identified as a specific command (click command), so that the same operator can also be used, the number of operation keys etc. of the commander device can be reduced, and the command device is compact and has good operability Can be realized.

  In addition, when a specific operation is performed as an operation performed using the displacement information and the display image based on the specific command, the movement range of the pointer image in the display image performed according to the displacement information received thereafter is By restricting only a range necessary as an operation to be executed next to a specific operation, the operability of the commander device used as an air mouse can be improved. That is, by not moving to a place where the pointer is not necessary, the pointer can be smoothly moved with respect to a target position such as an icon on the display.

  Further, when an operation using the commander device as an air mouse is performed on the display screen in the edit mode or the standby mode, a screen switching operation area is prepared at the edge of the pointer movable range in the display video. Thus, the pointer movement can be smoothly executed when the screen mode is switched.

  The headset device allows the audio signal obtained by the microphone means to be transmitted by the audio transmission means, and the information receiving means of the video camera device is also capable of receiving this audio signal, so that the user Can be recorded on the recording medium. For example, the conversation between the user and the interviewee can be recorded together with the video by both the microphone sound of the commander device and the microphone sound of the headset device.

The related operations necessary for the image processing are performed so that the user can easily perform imaging and editing.
The following explanation is made on the assumption that transmission / reception of information among the video camera 10, the microphone commander 80, and the headset 120 is performed using radio waves, but a communication method using other media such as infrared rays may be adopted. Good. Different communication methods may be employed between the video camera 10 and the microphone commander 80 and between the video camera 10 and the headset 120.

2. Usage example

The usage state of the imaging system of this example is illustrated in FIGS.
FIG. 7 shows an image when the video camera 10 is mounted on the camera platform 1 and used.
The user wears the headset 120 on his / her head so that the image display on the viewfinder unit 120 can be seen, and the microphone 124 can collect his / her voice.
Then, for example, the direction control lever 3 of the camera platform 1 is operated with one hand to control the imaging direction, and the microphone commander 80 is held with the other hand so that the other party and surrounding sounds can be collected. The start / end operation and the marking operation of the video camera 10 may be performed with the ST / ST key 86 and the mark / click key 87 in the microphone commander 80.
Although FIG. 7 shows an example in which the video camera 10 is installed at a certain fixed point and imaging is performed, the user may be away from the camera platform 1 and the video camera 10. This is because operation and video monitoring can be performed by the microphone commander 80 and the headset 120. Of course, the panning, tilting, and zooming operations can be performed by the microphone commander 80 even at a position away from the camera platform 1 and the video camera 10, so that the imaging direction can be controlled in an arbitrary direction.

  FIG. 8 shows a state where the user holds the video camera 10 at a low position and performs imaging from a low angle. In this case, although the microphone commander 80 is not provided, each operation element provided in the video camera 10 may be used for necessary operations. In addition, since a captured image from a low angle can be confirmed by the viewfinder unit 122 of the headset 120, it is not necessary for the user to squat down or lie down to lower the line of sight.

FIGS. 9A and 9B show an example in which the user does not use the pan head 1 but uses the video camera 10 on his shoulder. In this case, the arc-shaped pad 19 at the bottom of the main body 11 is placed on the shoulder, and the video camera 10 (for example, the grip 18 and the handle 13) is held with one hand. Then, the microphone commander 80 is used with the other hand.
This type of usage is suitable when the user himself / herself walks and images in a wide range. In addition, although an image at an angle of the height of the shoulder is taken, since the captured image can be monitored by the viewfinder unit 122 of the headset 120, it is not necessary to lower the line of sight. It is the same as in the case of.

  FIG. 10 shows an example in which the video camera 10 is placed on the head, and FIG. 11 shows an example in which the video camera 10 is lifted higher. In the case of applying to the head as shown in FIG. 10, the sense of weight can be eased by the arc-shaped pad 19 and the poor sitting can be eliminated. Since the monitor image can be confirmed by the viewfinder unit 122, imaging from a high angle is facilitated as shown in FIGS.

For example, as described above, the imaging system of this example can easily perform imaging at any angle by using at least the video camera 10 and the headset 120.
Further, when the video camera 10 is fixed to the camera platform 1 or the video camera 10 can be held with one hand, the microphone commander 80 can be used. Can be done at the same time.

In the imaging system of the present example, various edits can be performed on the recorded video, but the editing operation is at least within a range in which communication with the video camera 10 is possible, and the user can use the microphone commander 80 and the headset. This is possible by using 120.

3. Internal configuration of each device 3-1 Microphone commander

As an internal configuration of each apparatus, a block diagram of the microphone commander 80 is shown in FIG.
The circuit configuration of the microphone commander 80 is roughly divided into a command generation unit 88, a microphone unit 89, a transmission processing unit 90, and a power supply circuit 100.
In response to the power switch 85 being turned on, the power supply circuit 100 supplies the operation power supply voltage VDD to each unit using a battery (dry battery or rechargeable battery) 101 housed in the microphone commander 80.

The command generation unit 88 is a part that generates command information corresponding to the operation of the operator of the user and displacement information for the user to use the microphone commander 80 as an air mouse.
The command generation unit 88 includes a movement sensor unit 91, a controller 92, an operation unit 93, a ROM 94, and a modulation unit 95.
The movement sensor unit 91 is a sensor unit that detects the movement of the microphone commander 80 itself. By using an angular velocity sensor, an acceleration sensor, or the like, a position displacement caused by an operation of moving (shaking) the microphone commander 80 up, down, left, or right by the user. Detect information. In this example, an example using an angular velocity sensor will be described in detail later.
The positional displacement information of the microphone commander 80 itself output from the movement sensor unit 91 is supplied to the controller 92.
The operation unit 93 refers to each operator formed on the microphone commander 80. That is, the ST / ST key 86, the pan / tilt key 83, the zoom key 84, and the mark / click key 87. When there is an operation by these operators, the controller 92 detects the operation.

The controller 92 is formed by a microcomputer, and monitors the output of the movement sensor unit 91 and the operation of the operation unit 93, and receives command information stored in the ROM 94 according to the detected position displacement information or operation information. Read and output to modulation section 95.
In the ROM 94, command information corresponding to the ST / ST key 86, command information corresponding to the pan / tilt key 83, command information corresponding to the zoom key 84, mark / click key 87 The command information that is the code corresponding to is stored.
For example, when the ST / ST key 86 is pressed, the controller 92 reads command information corresponding to the ST / ST key 86 from the ROM 94 and supplies the command information to the modulation unit 95.
As will be described in detail later, the controller 92 generates x and y displacement information corresponding to the position displacement information in the movement sensor unit 91 and supplies the code as the x and y displacement information to the modulation unit 95.
The modulation unit 95 performs a predetermined modulation process on the code (command information or x, y displacement information) supplied from the controller 92 and outputs the code to the transmission processing unit 90.

  The microphone unit 89 includes a microphone 82, a microphone amplifier 96, and a modulation unit 97. The audio signal that has been converted into an audio / electric signal by the microphone 82 that is a sound collecting element is amplified by the microphone amplifier 96, is subjected to predetermined modulation by the modulation unit 97, and is supplied to the transmission processing unit 90.

The transmission processing unit 90 is a part that transmits the command information or the x and y displacement information supplied from the command generation unit 88 and the audio signal supplied from the microphone unit 89 to the video camera 10, for example, the multiplexing processing unit 98. And a transmission unit 99 is provided.
The multiplexing processing unit 98 multiplexes the command information, x, y displacement information, and audio signal according to a predetermined transmission method. The multiplexed transmission signal is modulated at a predetermined carrier frequency by the transmission unit 99 and transmitted as a radio wave signal.

For example, with such a configuration, the microphone commander 80 transmits and outputs command information, x, y displacement information, and audio signals to the video camera 10, but various other circuit configurations and transmission methods are conceivable.
The audio signal, command information, and x and y displacement information may be subjected to transmission modulation in the form of analog signals or may be subjected to transmission modulation in the form of digital signals.
For example, an audio signal may be supplied to the transmission processing unit 90 after being subjected to A / D conversion and digital modulation by the modulation unit 97, or may be modulated at a predetermined frequency by the modulation unit to be an analog signal. You may supply to the transmission process part 90 with a form.
Also, command information and x, y displacement information are supplied to the transmission processing unit 90 in the form of digital data, and transmission processing is performed in the form of analog signals by performing D / A conversion and modulation at a predetermined frequency in the modulation unit 95. You may supply to the part 90.

As processing of the multiplexing processing unit 98, when audio signals, command information, and x and y displacement information are input in the form of digital signals, time division multiplexing, error correction encoding, and compression processing may be performed. In the case of analog signal input, frequency multiplexing with different carrier frequencies may be performed.
Of course, as another modulation method, a modulation method such as QPSK modulation or FSK modulation may be adopted for transmission modulation processing.
In the example of FIG. 12, the audio signal, the command information, and the x and y displacement information are multiplexed and transmitted. However, two independent transmission circuit systems may be provided. When providing an independent transmission system, it is also conceivable to use different wireless communication media such that one is a radio wave system and the other is an infrared system.

By the way, the power switch 85 is not a type that directly opens and closes the power line as shown in FIG. 12, and the controller 92 performs on / off control of the power circuit 100 in response to the operation of the power switch 95 being detected. Is also possible.
Further, since the microphone 89 can be pulled out / stored as shown in FIG. 5, the microphone 89 itself may be used as a power switch. For example, the power is turned on by setting the drawer state, and the power is turned off by setting the storage state.

3-2 Video camera

The video camera 10 has a configuration as shown in FIG.
For example, the image sensor 41 is arranged in a pixel matrix corresponding to each color of R (red), G (green), and B (blue), or each color of Ye (yellow), Cy (cyan), and Mg (magenta). It consists of a CCD (CHARGE COUPLED DEVICE) that forms a two-dimensional image area.
Then, a light beam from the subject taken in from the lens mechanism 12 is imaged on the CCD, and an electric charge corresponding to the light amount is output as an electric signal. That is, video signals as R, G, and B signals are output.
The video signal output from the image pickup device 41 is supplied to the image pickup signal processing unit 42 where CDS (correlation double sampling) data extraction processing, AGC amplification processing, and the like are performed. , B digital data.

The R, G, and B signals (video data) converted into digital data by the A / D converter 43 are subjected to predetermined data compression processing by the image compression unit 44.
The data compression process is in accordance with the recording format of the disk 90 as a recording medium, and the recording on the disk 90 is compressed based on the recording format set according to the circumstances such as capacity and frequency band. It is what Therefore, when a method that does not require data compression is adopted as the recording format of the disk 90, processing in the image compression unit 44 is not necessary.

The video data processed by the image compression unit 44 is taken into the buffer memory 45.
For the write operation to the buffer memory 45, the write address Wad is supplied from the address generator 46, and the buffer memory 45 stores the video data supplied from the image compression unit according to the write address Wad.
The address generator 46 has a write address counter, a read address counter, a clock generator, etc., and generates a write address Wad based on the count value of the write address counter, and generates a read address Rad based on the count value of the read address counter. To do. Write / read control for the buffer memory 45, that is, the generation of the write address Wad and the read address Rad is in response to a write request from the controller 40 or the image compression unit 44 or a read request from the controller 40 or the recording processing unit 47. Will be executed.

For example, the image compression unit 44 periodically outputs a write request in accordance with the output of the video data, whereby the write address counter of the address generator 46 performs a counting operation and outputs a write address Wad, thereby performing an imaging operation. The obtained video data is taken into the buffer memory 45 sequentially.
Note that the clock generated by the clock generator, which is the reference for the count operation of the write address counter, is kept in synchronization with the CCD transfer operation clock in the image sensor section 41.

The video data captured in the buffer memory 45 is read according to the read clock Rad and supplied to the recording processing unit 47 and the monitor image generating unit 51.
The recording processing unit 47 is a part that generates a recording signal for the disc 90 loaded in the video camera 10 as a video / audio recording medium. That is, the video data read from the buffer memory 45 is subjected to modulation processing, error correction code addition processing, and the like, and converted into a data format in a format corresponding to the disk 90. Then, the video data is supplied to the recording / reproducing head unit 48.
The recording / reproducing head unit 48 performs a data recording operation on the disk 90 in accordance with a recording signal from the recording processing unit 47.
The recording processing unit 47 or the controller 40 issues a read request to the address generator 46 so as to read the video data from the buffer memory 45 at an appropriate timing according to the recording operation status in the recording / reproducing head unit 48.

The radio wave signal information transmitted from the transmitter 99 of the microphone commander 80 described above is received by the receiver 60, and the received signal is supplied to the audio decoder 61 and the command decoder 62.
The audio decoder 61 demodulates the audio signal collected by the microphone 82 (by performing A / D conversion if necessary) by performing decoding processing according to the audio signal transmission method in the microphone commander 80, and performs digital processing. The audio data is supplied to the recording processing unit 47.
The recording processing unit 47 encodes the audio data supplied from the audio decoder 61 together with the video data read from the buffer memory 45 in accordance with the recording format, and supplies the encoded data to the recording / reproducing head unit 48 as recording data. .

As will be described later, an audio signal collected by the microphone 124 of the headset 120 is also transmitted by the transmission circuit in the transmitter / battery pack 123 and received by the reception unit 60. This audio signal is also decoded by the audio decoder 61 and supplied to the recording processing unit 47.
Note that both the sound collected by the microphone 82 of the microphone commander 80 and the sound collected by the microphone 124 of the headset 120 are recorded on the disk 90, but the sound of both microphones is distinguished as this recorded data. For this reason, a recording process in which audio signals from the microphones 82 and 124 are recorded by being distributed to both channels of the 2-channel stereo system is conceivable. For example, the carrier frequency used for transmission in the microphone commander 80 and the headset 120 may be set as different frequencies so that the receiving unit 60 can receive both frequencies individually.
However, a mode is also conceivable in which the user uses the microphone 124 of the headset 120 as a so-called income for communication with another operator or the like.
When the microphone 124 is dedicated to the intercom, the receiving unit 60 may not receive and demodulate the transmission radio wave of the audio signal collected by the microphone 124.
When the microphone 124 can be used for both recording sound collection and intercom switching, the switching operation is performed using the operation keys of the video camera 10 and received according to the switching operation state. It may be configured to control whether or not the reception execution by the unit 60 is performed.
Further, a method may be employed in which the recording sound collecting / incoming switching operation is performed on the headset 120 side, and the headset 120 switches the transmission carrier frequency of the sound signal in accordance with the operation. Of course, at this time, it is sufficient that the receiving unit 60 does not correspond to the carrier frequency for income, and no switching operation is required on the video camera 10 side.

The disk 90 is, for example, a recordable portable disk such as a phase change type optical disk, a magneto-optical disk, a write-once optical disk, or a magnetic disk. A head, a magnetic head, and the like are provided, and recording / reproduction with respect to the disk 90 is possible.
In this example, a disk-shaped recording medium is used. However, a tape-shaped recording medium such as a magnetic tape, a card-type recording medium, a solid-state memory device, or the like may be used.

  The disk 90 is rotationally driven by the spindle motor 57 in the CLV method (constant linear velocity) or the CAV method (constant angular velocity). The spindle servo / driver unit 56 performs driving and servo control of the spindle motor 57 based on an instruction from the controller 40.

Then, data is recorded by the recording head in the recording / reproducing head unit 48 in a state where the disk 90 is rotationally driven.
During a recording operation by the recording / reproducing head unit 48, servo error signals such as tracking servo, focus servo, and thread servo are generated by the servo processor 54 and supplied to the servo driver 55. The servo driver 55 outputs drive signals for head scanning focus, tracking control operation, sled movement operation, and the like of the recording / reproducing head unit 48 in accordance with the servo error signal.

When the recording / reproducing head unit 48 is performing a reproducing operation on the disk 90, the information read from the disk 90 is supplied to the reproduction processing unit 49 to be decoded.
The reproduction processing unit 48 performs demodulation processing and error correction processing according to the recording format on the disk 90 to extract video data and audio data. Also, management information and addresses for managing video / audio data recorded on the disk 90 are extracted, and the management information and address information are supplied to the controller 40.
In the reproduction processing unit 49, for example, reproduced audio data obtained by the decoding process is D / A converted and output as an analog audio signal to the audio output terminal 53A.
For example, the audio output terminal 53A is used as one terminal of the input / output terminal unit 32 shown in FIG. 3, so that a reproduced audio signal from the disk 90 can be supplied to an external device. Note that a reproduced audio signal may be output as a digital audio signal from the audio output terminal 53A.

The video data decoded by the reproduction processing unit 49 is taken into the frame memory 50 and supplied to the monitor image generating unit 51 at a predetermined timing.
The monitor image generation unit 51 functions as a processor that generates a video signal that is displayed on the viewfinder unit 122 of the headset 120 or an image displayed on an external display device.
The operation of the monitor image generation unit 51 is controlled by the graphic controller 58 according to the operation mode status based on an instruction from the controller 40. Further, the graphic controller 58 controls the character generator 67 to generate necessary character image signals in each operation mode, thereby forming a GUI operation screen described later.

  Since the monitor image generation unit 51 can also supply the video data read from the buffer memory 45 as described above, the monitor image generation unit 51 generates a video signal for display using the video data serving as the imaging monitor during imaging execution. In addition, during playback of the disk 90, a display video signal using the played back video data can be generated. Then, under the control of the graphic controller 58, a necessary character image is synthesized with the captured monitor video or the reproduced video, and a display image signal is generated and supplied to the transmission unit 52 and the video output terminal 53V.

  The transmission unit 52 performs modulation, frequency conversion, and the like on the display video signal supplied from the monitor image generation unit 51 according to a predetermined transmission format, and performs radio wave transmission to the headset 120. That is, a monitor image and a reproduced image are transmitted to the headset 120 according to the operation mode. Each image transmitted according to the operation mode will be described in detail later.

  Further, the video output terminal 53V is one terminal of the input / output terminal section 32 shown in FIG. 3, thereby supplying the playback video signal from the disk 90 to the external device and displaying the monitor image and the playback image on the external device. Can be made. The video output terminal 53V may be either a digital video signal output or an analog video signal output.

By the way, in this example, the audio signal is not transmitted from the video camera 10 to the headset 120, but the reproduction audio data decoded by the reproduction processing unit 49 and the audio from the microphone commander 80 decoded by the audio decoder 61 are used. A signal may be supplied to the transmission unit 52 so that the signal can be transmitted to the headset 120.
In this case, by providing the headset 120 with an audio demodulation circuit and an earphone, the user can listen to the monitor audio and the reproduced audio with the headset 120.
As described above, when the headset 120 is also used for communication with an operator, it is necessary to provide the headset 120 with an audio demodulation circuit and an earphone. Accordingly, the audio demodulation circuit and the earphone provided in the headset 120 can be switched between intercom communication and audio monitoring, and an audio signal can be transmitted from the transmission unit 52 so that the audio can be monitored on the headset 120 side. The system operation can be improved by effectively using the constituent parts of each device.

The controller 40 is formed by a microcomputer and controls the entire video camera 10.
The operation unit 63 corresponds to various operators (20 to 31) as shown in FIGS. 2 and 3, and the controller 40 monitors the operation state of the operation unit 63. When an operation is detected, necessary operation control corresponding to the operation is executed.
Of the information received by the receiving unit 60, the command information from the microphone commander 80 and the x and y displacement information are decoded by the command decoder 62 and supplied to the controller 40. For the command information input from the command decoder 62, the controller 40 executes control processing according to the command information.
The x and y displacement information is information for an air mouse function, which will be described later. The controller 40 manages this x and y displacement information in the coordinate system, and gives the information to the graphic controller 58 to provide a monitor image generation unit. The pointer display position is controlled on the display video signal generated in 51.

The zoom motor 59 performs an operation of moving the zoom lens in the lens mechanism 12 to change the zoom state from the wide side to the tele side. The drive control of the zoom motor 59 is executed by the controller 40 according to the zoom operation.
In addition, when the video camera 10 is mounted on the camera platform 1, an interface unit 66 is provided for the controller 40 to communicate with a circuit system (controller 71) in the camera platform 1. The controller 40 supplies pan operation information and tilt operation information to the camera platform 1 via the interface unit 66 according to the pan operation and tilt operation.

The power supply circuit 65 outputs the operating power supply voltage VDD to each part using the battery 64 housed in the battery pack 17.
Supply on / off of the power supply voltage VDD (that is, power on / off) is performed by the controller 40 controlling the power supply circuit 65 in response to detection of an operation of the power supply key 31. For this reason, the weak standby power supply voltage VST is always supplied to the controller 40, and the controller 40 can execute necessary operations such as power key operation detection and power on control even when the power is off.
For example, an AC adapter may be used, or an AC / DC converter may be incorporated so that a commercial AC power source can be used.

3-3 Head

FIG. 14 shows a circuit configuration in the camera platform 1.
The interface unit 70 is a part corresponding to the interface 66 of the video camera 10. When the video camera 10 is mounted on the camera platform 1 and each connector part of the interfaces 66 and 70 is connected, the controller 40 of the video camera 10 is connected. Communication of the controller 71 of the camera platform 1 becomes possible.

A pan driver 72 and a pan motor 73 are provided in the camera platform 1, and the controller 71 gives an instruction to the pan driver 72 in accordance with pan operation information from the controller 40 to drive the pan motor 73. As a result, the pan / tilt mechanism 5 shown in FIG. 1 is rotated to the left and right, and the panning operation as the imaging direction of the video camera 10 is executed.
Further, a tilt driver 74 and a tilt motor 75 are provided in the camera platform 1, and the controller 71 gives an instruction to the tilt driver 74 in accordance with tilt operation information from the controller 40 to drive the tilt motor 75. As a result, the pan / tilt mechanism 5 shown in FIG. 1 is rotated up and down, and the tilt operation as the imaging direction of the video camera 10 is executed.

In addition, a receiver and a command decoder similar to the receiver 60 and the command decoder 62 of the video camera 10 are provided in the camera platform 1, and pan operation and tilt operation by the pan / tilt key 83 of the microphone commander 80 are directly detected to perform panning. Drive and tilt drive may be executed.
The pan head 1 may be configured such that the pan driver 72 and the tilt driver 74 are directly controlled by the controller 40 of the video camera 10 without providing the controller 71 in the pan head 1.

3-4 Headset

A block diagram of the headset 120 is shown in FIG.
The circuit configuration of the headset 120 roughly includes a viewfinder unit 130, a microphone unit 131, and a power supply circuit 139.
The power supply circuit 139 uses the battery (dry battery or rechargeable battery) 140 stored in the transmitter / battery pack 123 in response to the power switch 125 shown in FIG. 6 being turned on. Is supplied to each part.
That is, when the power switch 125 is turned on, the switches 125a and 125b in FIG. 15 are closed, and the operation power supply voltage VDD from the power supply circuit 139 is supplied to the viewfinder unit 130 and the microphone unit 131.
Although not shown in detail in FIG. 6, for example, the power switch 125 can be switched in four stages. Then, the power is turned off (= switches 125a and 125b are turned off), only the viewfinder unit 122 is turned on (= only the switch 125a is turned on), only the microphone unit 131 is turned on (= only the switch 125b is turned on), the viewfinder unit 122 Four power states can be established, ie, the microphone 131 is turned on (= switches 125a and 125b are turned on).
As the power operator, two switches of two-stage switching may be used as the switches 125a and 125b, respectively. That is, a switch such as the power switch 125 in FIG. 6 is provided exclusively for the viewfinder unit 122 and the microphone unit 131.

The viewfinder unit 122 is a part for displaying the display video signal transmitted from the video camera 10 to the user.
The viewfinder unit 122 includes a receiving unit 132, a video decoder 133, a display controller 134, and a display unit 135.

The reception unit 132 receives the transmission signal of the display video signal transmitted from the transmission unit 52 of the video camera 10 and supplies the display video signal to the video decoder 133. The video decoder 133 demodulates the received signal to obtain a display video signal.
The decoded display video signal is supplied to the display controller 134.
The display controller 134 functions as a display driver for the display unit 135 such as a liquid crystal panel, and causes the display unit 135 to perform a display operation of the display video signal supplied from the video decoder 133.
The display video signal to be displayed includes an image monitor screen of a captured image including a situation presentation character at the time of capturing and recording, a standby screen with a character for the GUI function, and an editing screen with a character for the GUI function, as will be described later. Etc.
With this display operation, a captured image and a captured state are presented to a user wearing the headset 120, and advanced editing work by a GUI operation is enabled.

The microphone unit 131 includes a microphone 124, a microphone amplifier 136, a modulation unit 137, and a transmission unit 138. As shown in FIG. 6, the audio signal that is output after being converted into an audio / electric signal by the microphone 124 positioned at the mouth of the user wearing the headset 120 is amplified by the microphone amplifier 136, and then is modulated by the modulation unit 137. Modulation is performed and supplied to the transmission unit 138.
The transmission unit 138 transmits and outputs the audio signal modulated by the modulation unit 137 at a predetermined carrier frequency using radio waves.
The audio signal transmitted and output from the transmission unit 138 is received by the receiving unit 60 of the video camera 10 as described above, and is decoded into an audio signal by the audio decoder 61 and digitized. The digital audio data is supplied to the recording processing unit 47 and can be recorded on the disk 90.

By the way, as described above, a power supply switching configuration is employed in which only the microphone 131 or only the viewfinder 130 can be powered off.
For this reason, for example, when the user's voice collected by the microphone 124 is not desired to be recorded on the disk 90, it is convenient that only the microphone unit 131 can be turned off. Conversely, when the headset 120 is used only as a microphone, the battery 140 can be saved by turning off the viewfinder unit 130.
In addition, as described above, when the microphone unit 131 is used for an income, it is very preferable that only the microphone unit 131 can be turned on.

  The display unit 135 is, for example, a liquid crystal panel. However, the display mode can be switched between a state in which a display image is displayed and a state in which external light is allowed to pass without displaying the image, that is, in a transparent or translucent state. Is preferable. As a result, when the user does not need to view the display image while wearing the headset 120, the display unit 135 can prevent one eye from being blocked. If the display unit 135 is transparent or semi-transparent when the headset 120 or the viewfinder unit 122 is turned off (that is, when no power is supplied), imaging or the like is performed. Even if the headset 120 is worn in a state where the user is not wearing, the user's one eye is not blocked, which is convenient.

In this example, the power switch 125 is turned on / off. However, the power may be turned on / off in conjunction with the power operation of the video camera 10.
For example, by including a power command in the signal transmitted from the transmission unit 52 and received by the reception unit 132, interlock control can be performed.
Also, the viewfinder unit 122 and the microphone unit 131 may not be turned on / off individually. For example, there is a case where it is preferable to use a common power switch, for example, when not considering an income application or when priority is given to simplifying the circuit configuration.

4). Operation mode 4-1 Mode transition

The imaging system of this example is configured by the devices configured as described above. In this imaging system, various modes of operation are possible by switching modes mainly as shown in FIG. Is done.
The mode switching operation is performed by the mode switch 24 shown in FIG. 3, and the video camera 10 is switched between the imaging mode and the editing mode in FIG. 16 by this mode switch.

The imaging mode is a mode for recording an imaged video signal (and an audio signal) on the disk 90.
In this imaging mode, the standby mode and the recording mode are switched by operating the ST / ST key 21 or 86.
The standby mode is a standby operation state during recording standby, and the recording mode is an operation state during execution of imaging (recording on a disk).
In other words, the video camera 10 first enters the imaging standby state as the standby mode by being set to the imaging mode by the mode switch 24. When the user operates the ST / ST key 21 or 86 to start imaging, the video camera 10 shifts to a recording mode, and imaging recording, that is, subject video signals and audio signals from the microphones 82 and 124 are recorded on the disk 90. The recording operation is performed.
Further, when the user again operates the ST / ST key 21 or 86 as the imaging ends, the video camera 10 returns to the standby mode and enters the standby operation state.

  The edit mode switched from the imaging mode (standby mode or recording mode) by the mode switch 24 is a mode for reproducing video / audio recorded on the disk 90 and editing video / audio. In this editing mode, as will be described later, advanced editing processing using a GUI operation is possible.

  The operation modes will be described below separately for the standby mode, the recording mode, and the edit mode. In the video camera 10, the corresponding operation for information transmitted from the microphone commander 80 or the headset 120 changes in each mode. It will be. This is collectively shown in FIG. In FIG. 17, “◯” indicates input acceptance, and “×” indicates input ignorance.

  Audio signals transmitted from the microphone commander 80 or the headset 120 are accepted only in the recording mode. That is, processing as an audio signal to be recorded is performed in the recording mode, but processing for a received audio signal is not performed in other modes. However, when a sound output function using an earphone or the like is added to the headset 120, the sound signal received by the receiving unit 60 is always transmitted from the transmitting unit 52 regardless of the mode, and the user collects the sound with the microphone commander 80. It may be possible to monitor the voice being played.

  For the ST / ST key 86 of the microphone commander 80 (and the ST / ST key 21 of the video camera 10 itself), the controller 40 accepts an imaging (recording) start operation in the standby mode and an imaging (recording) end operation in the recording mode. In response to the operation, the imaging start or end (transition between standby mode and recording mode) is performed.

  When the command information by the mark / click key 87 of the microphone commander 80 is received, the controller 40 accepts the command information as a marking operation in the recording mode, but in the standby mode and the editing mode, the GUI screen Accepted as a click operation above. The GUI operation uses the microphone commander 80 as an air mouse, and the click operation key for executing this function is also used as a marking operation key necessary only in the recording mode.

  When command information as the pan / tilt key 83 and the zoom key 84 (and the zoom key 23 of the video camera 30 itself) is input, the controller 40 accepts the command only in the standby mode or the recording mode, and pans the pan head 1. / Tilt operation control or zoom control for the zoom motor 59 is performed. These operations are invalid in the edit mode.

  The air mouse command is x, y displacement information for using the microphone commander 80 as a mouse for moving a pointer on the GUI screen. The x, y displacement information is accepted as information effective in the standby mode and the edit mode in which the microphone commander 80 is used as an air mouse, and necessary processing, that is, on the display video transmitted from the transmission unit 52. The pointer image generation process, the management of the pointer position, and the like are performed.

In the imaging system of this example, the function of the imaging system is changed by switching the three modes (standby mode, recording mode, and editing mode) that are the operation modes as modes of the video camera 10 as described above. However, in this example, it is assumed that the microphone commander 80 and the headset 120 itself have no change in the transmission output contents and the display operation control itself according to the function change (mode change of the video camera 10).
That is, the microphone commander 80 always transmits and outputs a voice signal, command information, and x and y displacement information as information transmission means. Then, in the video camera 10 on the receiving side, the selection and function determination of the audio signal, command information, x, y displacement information received according to the operation mode are performed.
In addition, the headset 120 performs display output of the transmitted display video and always transmits an audio signal obtained by the microphone 124. The change according to the mode as the video for display and the processing of the audio signal are performed inside the video camera 10 (monitor image generation unit 51, audio decoder 61), and the headset 120 simply has a display function and a microphone function. Only to.

  However, an operation method in which information output from the microphone commander 80 itself is selected according to the operation mode of the system, or the headset 120 controls the display screen according to the mode and turns on / off the audio signal transmission. Of course, it is also possible to make it. In this case, the microphone commander 80 and the headset 120 may be configured to detect the operation mode of the video camera 10. As a mode detection method, the video camera 10 is provided with a mode information transmission unit, the microphone commander 80, and the headset 120 is provided with a mode information reception unit, and the microphone commander 80 and the headset 120 detect the mode state of the video camera 10. However, a method of automatically setting the mode in accordance with this can be considered.

It is also conceivable that the microphone commander 80 and the headset 120 are provided with a mode operator such as the mode switch 24 of the video camera 10 so that the user can switch between the editing mode and the imaging mode.
Further, the microphone commander 80 may be used as a mode switch by utilizing that the microphone 82 is a type that can be pulled out / stored. That is, the imaging mode (standby mode or recording mode) is set in the drawer state, and the editing mode is set in the retracted state.

4-2 Standby mode

The processing of the controller 40 in each mode for realizing the function according to the above mode will be described.
First, the standby mode processing is shown in FIG.

  The standby mode is a mode in which subject selection, setting of an imaging direction, a zoom state, and the like can be executed as a preparation stage before shifting to the recording mode. When entering the standby mode, the controller 40 first displays a standby screen as step F101. To start. That is, the monitor image generation unit 51 uses the subject-side video supplied from the buffer memory 45 and the video obtained from the character generator 67 to generate a display video signal as a standby screen as shown in FIG. The operation to be displayed on the display unit 135 of the set 120 is started. The contents of the standby screen as shown in FIG. 30 will be described later.

  As can be seen from FIG. 17 described above, in the standby mode, the controller 40 accepts operations of the ST / ST keys 86 and 21, pan / tilt key 83, and zoom keys 84 and 23.

When the ST / ST key 86 or 21 is operated, the controller 40 recognizes the operation as an imaging start operation, and shifts the processing from step F102 to recording mode processing described later.
When command information is received by operating the pan / tilt key 83, the process proceeds from step F105 to F110, and information on the pan or tilt operation is supplied to the camera platform 1. Accordingly, the camera platform 1 drives the pan / tilt mechanism 5 to realize the imaging direction (angle) state requested by the user.
When the zoom key 84 or 23 is operated, the controller 40 proceeds from step F106 to F111, and controls the zoom motor 59 in accordance with the command information to change the zoom state by the zoom lens in the lens mechanism 12 to the tele side or wide side. Move to the side.

In the standby mode, the GUI function using the microphone commander 80 as an air mouse is effective.
Therefore, the pointer 210 is displayed on the standby screen as shown in FIG. 30, but the user can move the pointer 210 on the screen by shaking the microphone commander 80 held in his hand up, down, left and right.
That is, the microphone commander 80 transmits its own displacement state to the video camera 10 as x, y displacement information, but the controller 40 proceeds from step F103 to F107 in response to reception of the x, y displacement information. Based on the received x and y displacement information, the display position of the new pointer 210 is calculated. In step F108, the processing of the monitor image generation unit 51 is controlled via the graphic controller 58 so that the pointer 210 is displayed at the calculated pointer position. That is, the movement display control of the pointer 210 is performed.

The mark / click key 87 functions as a click key. For this reason, if command information based on the operation of the mark / click key 87 is detected, the process proceeds from step F104 to F109, and the current point in time is detected. Depending on the position of the pointer 210 on the standby screen and the click operation state, enter processing (decision operation processing), icon drag processing, and the like are performed.
The configuration for using the microphone commander 80 as an air mouse, the pointer position calculation process in step F107, and the enter process in step F109 will be described later.

4-3 Recording mode

When the ST / ST key 86 or 21 is operated from the standby mode to enter the recording mode, the controller 40 performs the processing of FIG.
The recording mode is a mode for performing an actual imaging operation, that is, a recording operation of video / audio on the disk 90. When the recording mode is entered, first, the controller 40, in step F201, the video signal captured by the imaging element unit 41, The audio signal captured by the audio decoder 61 is supplied to the recording processing unit 47. Then, the recording / reproducing head unit 48, the spindle servo / driver 56, and the servo processor 54 are controlled to start the operation of recording the picked-up video and sound on the disk 90.
At the same time, a video image for display as a monitor screen in FIG. 32 is used by using the subject-side video (recorded video) supplied from the buffer memory 45 and a predetermined character video obtained from the character generator 67 in the monitor image generator 51. And the operation of displaying on the display unit 135 of the headset 120 is started. The contents of the monitor screen as shown in FIG. 32 will be described later.

  As can be seen from FIG. 17 described above, the microphone commander 80 does not function as an air mouse in the recording mode. Then, the controller 40 accepts the operation of the ST / ST keys 86 and 21, the operation of the pan / tilt key 83, the operation of the zoom keys 84 and 23, and the operation of the mark / click key 87 (and the mark key 22).

When the ST / ST key 86 or 21 is operated, the controller 40 recognizes the operation as an imaging end operation, and advances the process from step F202 to F209 to execute the recording / reproducing head unit 48, the spindle servo / driver 56, and the servo processor 54. The recording operation by is stopped.
In step F210, the management information recorded in a predetermined area on the disc 90 is rewritten according to the recording operation status up to that point, and for example, the data portion to be recorded at that time is managed as a cut that is one imaging unit. It can be so.
When the processing associated with the end of the recording is completed, the processing is shifted to the standby mode processing of FIG.

When command information is received by operating the pan / tilt key 83 in the recording mode, the process proceeds from step F204 to F207, and information on the pan or tilt operation is supplied to the camera platform 1. Accordingly, the camera platform 1 drives the pan / tilt mechanism 5 to realize the imaging direction (angle) state requested by the user.
When the zoom key 84 or 23 is operated, the controller 40 advances the process from step F205 to F208, controls the zoom motor 59 according to the command information, and sets the zoom state by the zoom lens in the lens mechanism 12 to the tele side. Or move it to the wide side.

In the recording mode, the microphone commander 80 is not used as an air mouse, and the mark / click key 87 is handled as a mark operation key.
For this reason, when the command information by the operation of the mark / click key 87 is input, or when the operation of the mark key 22 of the video camera 10 main body is detected, the process proceeds from step F203 to F206 to perform the marking process. For example, information indicating a recording point in a cut such as a time code of a recorded video at that time is held. Such mark information is written in a predetermined area of the disk 90 when the management information is updated in step F210.

4-4 Edit mode

The processing of the controller 40 when the editing mode is set by the mode switch 24 is as shown in FIG.
The edit mode is a mode in which the video recorded on the disc 90 can be reproduced or edited. When the edit mode is entered, the controller 40 first starts displaying the edit screen in step F301. That is, using the disc playback video supplied from the frame memory 50 and the predetermined video obtained from the character generator 67 to the monitor image generation unit 51, the preview screen, trim / edit screen, clip / arrange screen shown in FIG. Display video signals as various editing screens are generated, and the operation of displaying them on the display unit 135 of the headset 120 is started. The contents of each editing screen will be described later.

As can be seen from FIG. 17 described above, in the editing mode, the controller 40 accepts only the air mouse command and the operation of the mark / click key 87.
That is, only the GUI function using the microphone commander 80 as an air mouse is enabled in the edit mode.
Therefore, as shown in FIG. 33, the pointer 210 is displayed on the screen in the edit mode, and the user can move the pointer 210 on the screen by shaking the microphone commander 80 held in his hand up and down and left and right. Can do.
That is, the microphone commander 80 transmits its displacement state to the video camera 10 as x, y displacement information, but the controller 40 proceeds from step F302 to F304 in response to reception of the x, y displacement information. Based on the received x and y displacement information, the display position of the new pointer 210 is calculated. In step F305, the process of the monitor image generation unit 51 is controlled via the graphic controller 58 so that the pointer 210 is displayed at the calculated pointer position. That is, the movement display control of the pointer 210 is performed.

The mark / click key 87 functions as a click key. For this reason, if command information based on the operation of the mark / click key 87 is detected, the process proceeds from step F303 to F306, and the current point in time is detected. Depending on the position of the pointer 210 on the editing screen and the click operation state, designation / determination operation processing such as click and double click, drag processing, drop processing, and the like are performed. By the air mouse operation using the pointer 210 moving operation and clicking operation, for example, video reproduction, screen mode change, editing execution, and the like can be performed.
The configuration for using the microphone commander 80 as an air mouse, the pointer position calculation process in step F304, and the enter process in step F306 will be described as an air mouse function.

5). Air mouse function

In this example, the microphone commander 80 outputs the position displacement information on the x and y coordinates and the command information as the click operation, so that the microphone commander 80 can be used as an air mouse for the GUI operation. It is as follows.
In this example, a movement sensor unit 91 using an angular velocity sensor is arranged in the command generation unit 88 of the microphone commander 80 so that x and y displacement information as movement information of the microphone commander 80 itself can be output.

FIG. 21 shows an angular velocity sensor 105 using a vibration gyro 105b.
A vibrating gyroscope has a characteristic that when a rotational angular velocity is applied to a vibrating object, a Coriolis force is generated in a direction perpendicular to the vibration, and this Coriolis force F is expressed as follows.
F = 2mvω
(M: mass, v: velocity, ω: angular velocity)
Accordingly, the angular velocity ω is proportional to the Coriolis force F, and the rotational angular velocity can be detected by detecting the Coriolis force F.

A driving piezoelectric ceramic 105c and a detection piezoelectric ceramic 105d are attached to the vibration gyro 105b, and an alternating signal which is an oscillation output of the oscillator 105a is applied to the driving piezoelectric ceramic 105c. In FIG. 21, when the vibrating gyroscope 105b is rotated in the Ω0 direction, a Coriolis force F is applied to the detecting piezoelectric ceramic 105d, and a voltage corresponding to the Coriolis force F is generated.
A minute voltage obtained from the detecting piezoelectric ceramic 105d is amplified by the amplifying unit 106, supplied to the A / D converter 107, and converted into digital data (voltage value E).

Therefore, for example, by comparing the voltage value E with the voltage values Va, Vb, Vc, Vd, for example, the operation of the device in which the vibration gyro 2 is mounted (for example, an operation of shaking the microphone commander 80 to the left and right) is detected. be able to.

Then, for example, when the vibration gyro 105b (105bx and 105by) is arranged in the microphone commander 80 as shown in FIG. However, the voltage E decreases due to the angular velocity ωy when it is swung in the right direction, so that the operation of the microphone commander 80 in the left-right direction can be detected.
That is, if the voltage E output from the vibration gyro 105by is Vc <E <Vd, it can be detected that the microphone commander 80 is swung leftward, and if Va <E <Vb, it is detected that it is swung rightward. it can.

Further, as the output of the vibration gyro 105bx, the voltage E increases due to the angular velocity ωx when the remote commander R is swung upward, and the voltage E decreases due to the angular velocity ωx when swung downward. The vertical movement of the commander 80 can be detected.
That is, if the voltage E output from the vibrating gyroscope 105bx is Vc <E <Vd, it can be detected that the microphone commander 80 is swung upward, and if Va <E <Vb, it is detected that it is swung downward. it can.

  When the voltage value E is Vb ≦ E ≦ Vc, it is set as a dead zone so as not to detect a slight movement of the microphone commander 80, and the user operates in a space in front of him / herself. As an air mouse, the pointer movement operation does not become unstable due to camera shake.

A configuration using such an angular velocity sensor 105 (105X, 105Y) as the movement sensor unit 91 in the command generation unit 88 shown in FIG. 12 is shown in FIG.
The output voltage from the angular velocity sensor 105X is supplied to the amplifying unit 106X and amplified to obtain an optimum level as an input to the A / D converter 107X. Then, it is digitized by the A / D converter 107X and output to the controller 92 as a voltage value EX.
Further, the output voltage from the angular velocity sensor 105Y is supplied to the amplifying unit 106Y and amplified so as to have an optimum level as an input to the A / D converter 107Y. Then, it is digitized by the A / D converter 107Y and output to the controller 92 as a voltage value EY.
The voltage values EX and EY are values corresponding to the movement of the microphone commander 80 in the X and Y directions, that is, the movement movement information in the X and Y directions.

  The controller 92 reads an X direction command (right movement command or left movement command) from the ROM 94 in accordance with the input voltage value EX (or generates a code value by calculation processing), and from the ROM 94 in accordance with the voltage value EY. A Y direction command (upward movement command or downward movement command) is read (or a code value is generated by arithmetic processing) and supplied to the modulation unit 95 as x, y movement information. Then, it is transmitted from the transmission processing unit 90 of FIG.

It becomes like this.
When the operation keys (pan / tilt key 83, zoom key 84, mark / click key 87, ST / ST key 86) on the microphone commander 80 as the operation unit 93 are operated, the controller 92 performs the processing from steps F501 to F504. The command information corresponding to the operated key is read from the ROM 94, sent from the modulation unit 95 to the transmission processing unit 90, and transmitted to the video camera 10.
When no key operation is performed, as steps F502 and F503, x displacement information corresponding to the value is output according to the input of the voltage value EX, and y displacement corresponding to the value according to the input of the voltage value EY. Output information.

In the video camera 10 to which command information, x, y displacement information is transmitted from the microphone commander 80 as described above, when command information as a click operation is detected as processing relating to the air mouse function, a pointer at that time is detected. Is performed according to the position and the click operation state (click, double click, drag, etc.) (steps F109 and F306 described above).
On the other hand, for the x and y displacement information, the pointer is moved on the screen accordingly (steps F108 and F305 described above).

  When x, y displacement information is input, the pointer 210 is moved on the screen accordingly, that is, a new pointer position is calculated (steps F107 and F304), and the screen is displayed at the calculated position. Data is sent to the graphic controller 58 so that the pointer 210 is displayed, and movement on the display is realized.

For this purpose, the controller 40 of the video camera 10 is provided with an xy coordinate system corresponding to the screen of the display unit 135 of the headset 120, whereby the position and operation of the pointer 210, and the image contents such as various icons. The correspondence is determined. That is, as shown in FIG. 26, for example, a coordinate system of 256 dots (0 to 255) in the x direction and 192 dots (0 to 191) in the y direction is constructed, and the pointer position P0 is used as this coordinate value. To figure out.
When x, y displacement information is input, x, y displacement information is added to the coordinate value of the previous pointer position P0, and a new pointer position coordinate is calculated.
When a click operation is performed, processing is performed according to the pointer position coordinates at the time of the operation and display contents (such as icons) grasped on the x and y coordinates.
The numerical value of the coordinate system of 192 × 256 dots in the vertical and horizontal directions is merely an example for explanation.

The pointer position calculation process in steps F107 and F304 described above is as shown in FIG.
In step F401, the controller 40 adds the detected x displacement information value Δx to the x coordinate value xp of the immediately preceding pointer position coordinate to obtain an added value xN.
In step F402, it is determined whether or not the current trim bar movement mode is selected. In this case, the process proceeds to the process of FIG. 28 as indicated by 1, which will be described later.
Normally, the process proceeds to step F403, and the detected value y of the y displacement information is added to the y coordinate value yp of the immediately preceding pointer position coordinate to obtain the added value yN.

In step F404, it is confirmed whether or not the value of the addition value xN is less than 0. If xN <0, the value of the addition value xN is forcibly set to “0” in step F405 and then the process proceeds to step F408. .
If xN <0, it is checked in step F406 whether the value of the addition value xN is 256 or more. If xN> 255, the value of the addition value xN is forcibly set to “255” in step F407. Then, the process proceeds to step F408.
If the value of the addition value xN is not less than 0 and not more than 255, the process proceeds to step F408 as it is.

In step F408, it is confirmed whether or not the value of the added value yN is less than 0. If yN <0, the value of the added value yN is forcibly set to “0” in step F409 and then the process proceeds to step F412. .
If yN <0, it is checked in step F410 if the value of the added value yN is 192 or more. If yN> 191, the value of the added value yN is forcibly set to “191” in step F411. Then, the process proceeds to step F412.
If the value of the added value yN is not less than 0 and less than 191, the process proceeds to step F412 as it is.

  In step F412, the addition value xN at that time is set as an x coordinate value xp as a new pointer position, and the addition value yN at that time is set as a y coordinate value yp as a new pointer position. That is, a new pointer position is determined.

By the above processing, for example, when the current pointer position P0 is (x, y) = (128, 66) in the xy coordinates of FIG. 26, the displacement information Δx in the x direction from the microphone commander 80 is +50, y Assuming that a numerical value of +30 is sent as the direction displacement information Δy, a new pointer position P1 is calculated as (x, y) = (178, 96), and this data is sent to the graphic controller 58 on the screen. The pointer position at is moved to position P1.
In addition, in the processing of steps F404 to F411, regarding the addition values xN and yN when the x and y displacement information is added respectively, when xN <0, xN = 0, and when xN> 255, xN = 255. When yN <0, yN = 0, and when yN> 192, yN = 191. Therefore, the pointer position is 192 × 256 dots from the coordinate system. There will never be an outside. That is, for example, even if the microphone commander 80 is swung to the left, the position of the pointer 210 on the screen is not moved to the left from the left corner of the screen.

This means that the pointer 210 can be easily moved to the corner portion on the display at the upper, lower, left and right corner portions on the screen if the moving amount of the microphone commander 80 is relatively large. That is, the left corner, the right corner, the upper corner, and the lower corner on the screen can be easily pointed.
Needless to say, the values of “192” and “256” in the processing of FIG. 27 differ if the dot size of the set coordinate system is different.

  As described above, in this example, the microphone commander 80 can be used as an air mouse by the pointer movement corresponding to the movement of the microphone commander 80 itself and the click operation. By setting a so-called GUI screen, various and advanced operations can be performed by the air mouse.

In this example, the angular velocity sensor is used to realize the air mouse function. However, the acceleration sensor, the tilt sensor, the geomagnetic sensor, etc. may be used to generate the x, y displacement information in the same manner. Good.
In addition, the microphone commander 80 can be operated so as to operate as a shuttle ball or a track ball as an operation unit, and can output the operation information, can output the operation direction information by the joystick, the direction keys such as four directions or eight directions Etc., and x and y displacement information may be output according to the operation.
Further, although the pointer is moved in two dimensions, x and y, a method of moving the pointer only in the x direction or the y direction may be adopted depending on the setting of the GUI screen. In this case, as a matter of course, the microphone commander 80 may be configured to output displacement information in a certain one-dimensional direction.

6). GUI function 6-1 Screen mode

The GUI operation realized by the display screen in each mode and the air mouse function of this example will be described.
FIG. 29 shows the transition of the screen mode.

In the case of the imaging mode, a display video signal serving as a standby screen during the standby mode and a display video signal serving as a monitor screen during the recording mode are generated by the monitor image generation unit 51, and the display unit of the headset 120 is displayed. 135 is displayed.
On the other hand, in the edit mode, three screen modes are prepared: a preview screen, a trim / edit screen, and a clip / arrange screen.
When the editing mode is set by the mode switch 24, the preview screen is first displayed, and thereafter, the three screen modes are switched according to the screen mode switching operation performed by the user through the GUI.
Note that the edit mode may be set so that a screen mode other than the preview screen is first set. Further, various screen modes may be set as the editing screen.

Hereinafter, the contents of each screen mode will be described. However, these are merely examples, and it goes without saying that the setting of the display contents, the type, the GUI operation method setting, and the like can be variously considered.
In each drawing, the screen parts described as the bar graph display 204, the trim bar display 230, and the story line display 250 are expressed in the form of diagonal lines, crossed diagonal lines, stippling, white outlines, stripes, and the like. This shows the difference in color of the display part.
The “click operation” used in the description is an operation of the mark / click key 87 of the microphone commander 80, and the “drag operation” is an operation of moving the microphone commander 80 up, down, left and right while holding down the mark / click key 87. The “drop operation” is an operation to release the mark / click key 87 from the drag operation state.

Each screen to be described is displayed on the display unit 135 of the headset 120 based on the display video signal generated by the monitor image generation unit 51 in the processing from steps F101, F201, and F301 in FIGS. It is what is displayed.
Further, the GUI operation on the standby screen and the edit screen and the operation accompanying therewith are operations realized by the processing in steps F107, F108, and F109 in FIG. 18 or steps F304, F305, and F306 in FIG.

6-2 Standby screen

The contents of the standby screen will be described with reference to FIGS.
FIG. 30 shows an example of a standby screen when a standby mode is first set for a new disc 90 that has not been imaged before, and FIG. 31 shows, for example, seven recording operations and recording seven cut images. It shows an example of a standby screen when the standby mode is set after being performed.

  During the standby mode, for example, a standby display 208 with characters “STANDBY” as shown in the figure is displayed on the video display 201 that is the captured video content of the subject captured by the imaging device unit 41, and is displayed to the user. This is a standby mode (that is, the recorded image is not recorded on the disk 90).

In the standby image, time displays 202 and 203, a bar graph display 204, a setting display 205, a zoom display 206, and a battery display 207 are performed. A pointer 210 corresponding to the air mouse function is displayed.
The time display 202 indicates the total time of the cuts that have been imaged so far, and the time display 203 indicates the total time of the cuts that are currently being imaged. Therefore, in the standby mode in which imaging (recording) is not executed, the time display 203 is 0 minute 0 second 0 frame.
Further, as the time display 202, at the time when recording (hereinafter, “recording” refers to imaging and recording operations which are operations in the recording mode) has been performed several times, as shown in FIG. The total time of all recorded cuts will be shown.

The bar graph display 204 shows the recording status on the disc 90. As shown in FIG. 30, when recording on the disk 90 is not executed, the bar in the bar graph display 204 is blank, but each cut is recorded in the bar as the recording of the cut is performed. Display by length separation according to time. For example, as shown in FIG. 31, the length portions (hatched portions) corresponding to the seven cuts C1 to C7 have a different color from the blank portions in the bar graph display 204, and the cuts C1 to C7 have their respective colors. It is divided according to the recording time length.
The cut indicates a portion recorded by a series of recording operations, that is, the operation timing of the ST / ST key 21 or 86 becomes a cut break.
From this bar graph display 204, the cut recording status of the disc 90 can visually confirm the length of each cut, the number of cuts, and the remaining amount as the recording capacity of the disc 90.
In addition, as a position on the bar graph display 204, a current point display 212 is performed as a current recording point, and a point where a marking operation is performed during recording is presented as a mark point display 211. Is done.

A setting display 205 displays various setting states of the video camera 10. For example, the image compression rate, autofocus mode, etc. are displayed.
Further, as the zoom display 206, it is displayed where the current zoom state is from the tele side to the wide side. The illustrated example shows a state where the zoom state is set to the widest side.
The battery display 207 indicates the remaining capacity of the battery 64 stored in the battery pack 17.

In the standby mode, the operation using the microphone commander 80 as an air mouse can be performed as described above.
With the air mouse function, the setting can be changed using the microphone commander 80 during the standby mode.
For example, as shown in FIG. 31, the setting of the image compression rate can be changed by positioning the pointer 210 at the display portion of the image compression rate in the setting display 210 and performing a click operation.
The same applies to other setting contents, and it is also possible to change on / off of the autofocus mode (that is, whether it is autofocus or manual), on / off of the camera shake correction mode, and the like. Furthermore, the zoom state can be changed by dragging an image indicating the zoom position in the zoom display 206. That is, the same operation as the zoom key 84 is possible.

6-3 Monitor screen

The monitor screen in the recording mode is as shown in FIG.
FIG. 32 shows an example of a monitor screen when the ST / ST operation is performed from the standby mode in FIG. 31 to shift to the recording mode.

During the recording mode in which recording is being performed, the captured video content of the subject that is captured by the image sensor unit 41 and recorded on the disk 90 is displayed as the video display 201. That is, it is an imaging monitor image.
Further, as the time display 202, in addition to the total time of the cuts C1 to C7 recorded so far, the total time obtained by adding the length of the currently recorded cut (cut C8) is displayed. As shown, the time of the cut C8 that is currently undergoing imaging is shown. Accordingly, the time displays 202 and 203 change as the recording progresses.

In the bar graph display 204, the currently recorded cut C8 is displayed in a different color from the already recorded cuts C1 to C7. The current point display 212 moves rightward on the bar graph as the recording operation proceeds. That is, it indicates the head portion of the cut C8.
If the marking process is performed during the recording of the cut C8, a mark point display 211 is added according to the marking timing in the cut C8 as shown in the figure.
Also on this monitor screen, the setting display 205, zoom display 206, and battery display 207 are performed in the same manner as the standby screen.
However, in the recording mode, the microphone commander 80 cannot be used as an air mouse, and therefore setting change by GUI cannot be performed. To change the setting during recording, operation keys on the microphone commander 80 and the video camera 20 are used.

6-4 Preview screen

In this example, when the video camera 10 is set to the edit mode, the edit screen is first a preview screen.
Examples of the preview screen are shown in FIGS. The preview screen is mainly a screen mode for reproducing cuts recorded on the disc 90.

First, in order to switch each screen mode as an editing screen, a preview area display 220, a trim area display 221 and a clip area display 222 are arranged at the upper and left and right corners of the screen.
In addition, a bar graph display 204 and time displays 202 and 203 are performed as in the standby screen and the monitor screen.
At the bottom of the screen, a preview key display 223, a trash box display 224, and search key displays 225 and 226 are displayed.

On this preview screen, an arbitrary cut can be selected and reproduced.
For example, when the cut C8 portion is clicked in the bar graph display 204, it is assumed that the cut C8 is selected, and the color of the cut C8 portion is changed.
The time display 202 displays the total time of all recorded cuts, and the time display 203 displays the total time of the selected cut.

When the preview key display 223 is clicked in a state where a certain cut is selected, the reproduction of the cut C8 is started.
That is, the controller 40 instructs each unit to reproduce the cut C8 portion of the disk 90, and a preview image is reproduced by the reproduced image that is reproduced and input to the monitor image generation unit 51 via the graphic controller 58 via the frame memory 50. Control to generate.
As a result, the display of the playback video from, for example, the top portion of the cut C8 is started as the video display 201.

In addition, a preview cursor 211 is displayed on the bar graph display 204 to indicate the current playback location. That is, the preview cursor 227 moves on the bar graph as the reproduction progresses.
A location to be reproduced (cut or position within the cut) can be moved to a desired location by clicking the search key displays 225 and 226. For example, when the search key 226 is clicked, reproduction can be executed from the head position of the next cut after the currently reproduced cut.

  Note that when the screen is shifted to the preview screen, for example, the latest cut may be selected. In this way, when the screen is moved to the preview screen, the cut recorded immediately before can be immediately reproduced and confirmed by simply clicking the preview key display 223.

The preview area display 220 includes coordinate values where y coordinate value = 0 in a coordinate system in which the pointer 210 as an air mouse is movable. That is, it is set as an area including the upper end of the xy coordinate system.
The preview key display 223, the trash box display 224, and the search key displays 225 and 226 each include a coordinate value where y coordinate value = 191 in a coordinate system in which the pointer 210 as an air mouse can move. That is, it is set as an area including the lower end of the xy coordinate system.

In the coordinate system in which the clip area display 222 and the pointer 210 are movable, a coordinate value where x coordinate value = 0 is included. That is, it is set as a region including the left end portion of the xy coordinate system.
The trim area display 221 includes a coordinate value where x coordinate value = 255 in the coordinate system in which the pointer 210 is movable. That is, it is set as a region including the right end portion of the xy coordinate system.

In addition to the bar graph display 204, these displays to be clicked are positioned at the end of the XY coordinate system, thereby improving air mouse operability. That is, if the microphone commander 80 is swung upward from the state where the pointer 210 is located near the center of the screen, the pointer 210 can be easily entered into the preview area display 220 without going too high.
Similarly, the pointer 210 can be easily moved in the clip area display 222 if it is swung relatively far to the left, and in the trim area display 221 if swung relatively far to the right.
Similarly, with respect to the preview key display 223, the trash can display 224, and the search key displays 225 and 226, it is easy to control the pointer position in the height direction, and the right and left controls at the height position are positioned within the desired display. be able to.
In other words, by arranging the display area to be clicked at the end of the coordinate system as much as possible, it is easy to perform the pointer movement operation with the air mouse, which must be unstable to perform the operation in the air. As a result, operability can be improved.

Each cut expressed in the bar graph display 204 can be reproduced as described above and various processes can be performed.
First, as shown as a drag operation DR1 in FIG. 34, by dragging / dropping a certain cut (for example, cut C8) to the trim area display 221, a transition to the trim / edit screen for trimming processing is made. Can do.
Also, as shown as a drag operation DR4, by dragging / dropping a certain cut (for example, cut C3) to the clip area display 222, the cut is registered as a clip, and a transition is made to a clip / arrange screen for performing necessary processing. be able to.
In this case, the selected cut is registered as a clip without trimming.

Even when a certain cut is not selected, the cut can be reproduced by dragging / dropping a certain cut (for example, cut C2) to the preview key display 223 as shown by the drag operation DR3. it can.
Further, when it is determined that a certain cut (for example, the cut C6) is unnecessary, the cut can be deleted by dragging / dropping the cut to the trash box display 224 as shown as the drag operation DR2. .
For example, as shown in FIG. 34, the deleted cut portion has the same color as the blank portion other than the cut in the bar graph display 204 to express that it has been deleted.

  However, the data is not actually deleted simply by dragging / dropping it to the trash box display 24. When the trash box display 224 is clicked, a menu display 228 is executed as shown in FIG. 35, and erase data and return data can be selected. By selecting the erase data, the cut of the trash box process is deleted, and by selecting the return data, the cut of the trash box process can be restored.

By the way, the editing state of the video performed in the editing mode such as the preview screen as described above, the trim / edit screen, the clip / arrange screen, which will be described later, is held by the controller 40 as an editing file. By instructing a disc playback operation or the like based on the above, it is possible to obtain a video as an editing result.
The deletion and update of data on the disk 90 is realized by the controller 40 rewriting the management information of the disk 40 according to the editing file. That is, the controller 40 performs management information update processing of the disk 90 at each required time according to the creation of the edit file. However, until the editing result is finalized, the controller 40 only creates an editing file, and the management information on the disk 40 is rewritten when the final instruction is given by the user. Is also possible. In this way, even if it is desired to redo editing, the original video state can be easily restored.

6-5 Trim / Edit screen

For example, the screen mode is shifted to the trim / edit screen by dragging / dropping a certain cut to the trim area display 221 or clicking the trim area display 221 as in the drag operation DR1 of FIG.
The trim / edit screen is a screen for performing an editing operation for trimming a necessary portion from a cut.

For example, as shown as the drag operation DR1 in FIG. 34, FIG. 36 shows a screen example when the screen proceeds to the trim / edit screen for the cut C8.
In the trim / edit screen, a preview area display 220, a trim area display 221 and a clip area display 222 are displayed for shifting to another screen mode by clicking or dragging, as in the preview screen.
As the bar graph display 204, the portion of the cut (cut C8) to be trimmed is highlighted in a color different from other cuts, and the user confirms the cut currently being edited. Be made possible.
In addition, as the time display 203, the total time of the cut to be edited is displayed.

In this trim / edit screen, a trim bar display 230, a flag display 231 and a trash box display 224 are displayed at the bottom of the screen (the part including the lower end of the xy coordinate system).
The trim bar display 232 represents the selected cut (for example, the cut C8) as the full length of the bar. That is, it is an image of an enlarged display of the cut portion selected in the bar graph display 204.
The mark point display 211 displayed corresponding to the bar graph display 204 is also reflected on the trim bar display.

On the trim bar display 230, the user can arbitrarily divide the selected cut.
That is, when the pointer 210 is moved to the flag display 231 and a drag operation is started, the trim bar moving mode is entered, and the movement flag display 234 is moved left and right on the trim bar display 230 in accordance with the pointer 210 as shown in FIG.
When the drag operation is canceled (dropped) at a certain position on the trim bar display 230, the flag set display 232 is displayed at that position, and the bar of the trim bar display 230 is separated at that position.
FIG. 36 shows a state in which the cut C8, which is the target of the trim bar display 230, is divided into parts DV1 to DV5 in the cut by the flag setting operation, and is further selected by clicking the part DV3. It shows the state that is in the middle. The part selected on the trim bar display 230 is highlighted in a different color from the other part parts.

Incidentally, in order to improve the operability of the flag setting operation for dividing the cut into a plurality of parts, the processing shown in FIG. 28 is performed as the pointer position calculation processing of the controller 40 based on the air mouse operation.
When the trim / edit screen is entered, the pointer position calculation processing of FIG. 27 proceeds from step F402 to F403, and pointer movement display control similar to the normal time is performed. Therefore, the same operability improvement as the preview screen can be achieved for the click target display portion arranged at the end on the screen (on the xy coordinates).
Here, when the drag operation is started from the flag display 231 as described above, the controller 40 recognizes that it has entered the trim bar movement mode, and the processing for the subsequent input of the x, y displacement information is changed from step F402 to step F413 in FIG. Will proceed.

  That is, when the x, y displacement information is input and the new pointer position is calculated, the controller 40 first calculates the detected value x of the x displacement information in step F401 of FIG. Add to the x coordinate value xp to obtain the added value xN. Next, the process proceeds from step F402 to step F413 in FIG. 27, and a specific y coordinate value Fy is forcibly set as the addition value yN regardless of the detected value y of the y displacement information.

Subsequently, in step F414, it is confirmed whether or not the value of the addition value xN is less than a specific x-coordinate value Fx1, and if xN <Fx1, the value of the addition value xN is forcibly set in step F415. After “Fx1”, the process proceeds to step F412 in FIG.
If xN <Fx1, it is checked in step F416 whether the value of the added value xN is larger than a specific x coordinate value Fx2, and if xN> Fx2, the added value is determined in step F417. After the value of xN is forcibly set to “Fx2”, the process proceeds to step F412.
If the value of the addition value xN is not less than Fx1 and less than or equal to Fx2, the process proceeds to step F412 as it is.
In step F412, the addition value xN at that time is set as an x coordinate value xp as a new pointer position, and the addition value yN at that time is set as a y coordinate value yp as a new pointer position. Decide.

Here, the y coordinate value Fy is a coordinate value including the trim bar display 210 as shown in FIG. The x coordinate value Fx1 is, for example, the x coordinate value at the left end of the flag display 231 and the x coordinate value Fx2 is, for example, the x coordinate value at the right end of the trash can display 224.
Then, as shown in FIG. 28, while the flag is being dragged, the pointer 210 (movement flag display 234) is displayed with the flag display 231, the trim bar display 234, and the trash can display, even if the microphone commander 80 is swung in the vertical direction. It can only be moved (dragged) in the left-right direction up to 224.
That is, while the flag is being dragged, an operation for mainly searching for the flag drop position on the trim bar display 230 is performed, so it is only necessary to move the left and right pointers on the trim bar display 234. In this case, since the pointer 210 is not moved up and down, the position on the trim bar display 230 can be selected very easily even when the microphone commander 80 is in an unstable space operation.
In this example, the trash can display 224 is also within the movable range, but the coordinate value Fx2 may be set to the coordinate value at the right end of the trim bar display 230 so that the trash can display 224 cannot be reached.
Further, the coordinate value Fx1 may be set to the coordinate value of the left end portion of the trim bar display 230, and the pointer 210 may be moved onto the trim bar display 230 at the start of the drag so that the flag display 231 cannot be reached during the drag. .

The trim bar moving mode in which the pointer movement is restricted is canceled by the flag drop operation, and the pointer 210 can be moved up and down and left and right within the screen range.
Although dragging of the flag is started, there is a case where it is desired to cancel the trim bar moving mode without performing flag dropping. In other words, it is a case where the cut part division is about to be executed but it is desired to cancel.
In such a case, for example, an operation setting example such that the trim bar moving mode can be canceled by performing flag drop at the position of the flag display 231 can be considered. In this case, it goes without saying that it is necessary to keep the flag display 231 within the drag-movable range.

Further, for example, by dragging a certain flag set display 232 set on the trim bar display 230 and dropping it in the area of the trash box display 224 or the flag display 231, the division point once executed can be eliminated.
Further, the part division point may be changed by dragging the flag set display 232 and moving it to another position on the trim bar display 230.
In these cases, the processing of FIG. 28 may be performed as the trim bar movement mode, and the pointer movement in the vertical direction may be restricted.

  Each part divided and set on the trim bar display 230 by the flag drop operation can be deleted by dragging to the trash box display 224. For example, as shown as a drag operation DR6 in FIG. 28, the part DV4 can be deleted as an unnecessary part in the cut C8 by dragging the part DV4 to the trash box display 224.

Each cut expressed on the bar graph display 204 on the trim / edit screen 38 and each part expressed on the trim bar display 230 can be registered as a clip.
For example, the part DV3 can be registered as a clip by dragging the part DV3 to the clip area display 222 as shown as a drag operation DR5 in FIG.
Further, for example, by dragging the cut C8 to the clip area display 222 in a state where the part DV4 is deleted by the drag operation DR6, the cut C8 in a state where the part DV4 is deleted can be registered as a clip.

6-6 Clip / Arrange screen

The recorded cut, the cut from which unnecessary portions are deleted on the trim / edit screen, or the part extracted as a part of the cut can be registered as a clip from the preview screen or the trim / edit screen as described above.
A clip refers to a portion selected as a video material, and registration is expressed on a clip / arrange screen as shown in FIG. 39 by registering a certain cut or part as a clip.

The clip / arrange screen displays a list of registered clips as clip video displays.
In this example, a maximum of nine clip video displays 240 can be displayed. However, when there are 10 or more registered clips, scroll key displays 229 and 229 are displayed above and below the clip area display 222. By clicking the scroll key display 229, the clip video display 240 can be scrolled to check all clips.
Of course, it is also possible to adopt a display control form in which the image size of the clip video display 240 is changed according to the number of registered clips so that a list can be displayed as much as possible.

When the cut or part is registered as a clip on the trim / edit screen or preview screen, the clip / arrange screen is displayed. The clip registered at that time is the last clip video in the clip video display 240. The display 240N is displayed separately from other clips, for example, with a white frame. Of course, when the first clip is registered, the display processing for distinction like the clip video display 240N is not necessarily required.
As the time display 203, the total time of the clip registered this time (the clip of the clip video display 240N) is displayed.
As each clip video display 240 (and 240N), for example, an image of a clipped part or cut start point is displayed.

In this clip / arrange screen, a preview area display 220, a trim area display 221, and a clip area display 222 are performed for shifting to another screen mode by clicking or dragging, as in the preview screen and the trim / edit screen.
Similarly to the preview screen, a preview key display 223, a trash can display 224, and search key displays 225 and 226 are displayed at the bottom of the screen.
These are arranged at the end of the screen (coordinate end) where the pointer 210 can be easily located as in other screens.

On the clip / arrange screen, a story line display 250 and a story time display 251 are performed.
The story line display 250 represents a clip used as a story. When no clip is selected, the story line display 250 is a simple bar display that represents nothing as shown in FIG.
The story time display 251 indicates the total time of a clip selected as a story. In the state shown in FIG. 39, the time is 0 minute 0 second 0 frame.

By dragging an arbitrary clip video display 240 to the story line display 250, a story is formed.
For example, as shown as drag operations DR8, DR9, DR10, DR11 in FIG. 40, by dragging / dropping each clip video display 240 to the story line display 250, the operation is performed on the story line display 250 according to the order in which the operations were performed. Clips are filled as selected clips CL1 to CL4. That is, the story line display 250 is divided according to the length of each clip. The portions of the selected clips CL1 to CL4 are displayed in a predetermined color.
As the story time display 251, the total time of the selected clip expressed on the story line display 250 is displayed.
For the clip filled in the story line display 250, a selected display 252 is displayed on the clip video display 240.

  The clip once selected in the story line display 250 can be trimmed again. For example, as shown as a drag operation DR12 in FIG. 41, by dragging / dropping the clip video display 240 of the selected clip to the trim area display 240, the trim / edit screen for this clip can be moved to perform the trimming process. The same applies to clips that are not selected in the story line display 250.

Also, clips that are once generated and displayed as the clip video display 240 on the clip / arrange screen, or clips that are filled as the selected clip in the story line display 250 are dragged to the trash box display 224 when it is determined that they are unnecessary. / Can be deleted by dropping.
However, in addition to editing that deletes the data itself, deletion may include processing to cancel clip registration and return to simple cuts or parts, or processing to cancel the selected clip state and return to simple clip registration.
Therefore, the processing contents as the trash can display 224 may be diversified by menu display or the like, or a dedicated display part (clip registration cancellation icon, selected clip cancellation icon, etc.) may be provided for each processing.

The clips selected in the story line display 250 are played back in the order of the clips, so that one story is finally formed. In other words, the user edits one story as, for example, a program by filling the story line display 250 with clips from each cut recorded on the disk 90 by the editing process described above.
When a clip is selected and a story (clip group) having a desired length is formed while confirming the story time display 251 as the story line display 250, the preview is displayed by clicking the preview key display 223. The sequential playback of the selected clip on the story line display 250 is started.
As shown in FIG. 42, the clip / arrange screen disappears from the display of one or a plurality of clip videos 240 and the playback video from, for example, the first part of the story is displayed as the video display 201.
That is, the controller 40 sequentially controls each part of the disk 90 corresponding to the selected clips CL1, CL2, CL3, and CL4, and is reproduced by the monitor image generation unit 51 via the graphic controller 58 to be reproduced in the frame memory 50. Control is performed so that a preview image is generated based on a reproduction image input via the.

In addition, a preview cursor 227 is displayed on the story line display 250, and the current playback location on the story is shown. That is, the preview cursor 227 moves on the story line display 250 as the reproduction progresses.
A location to be reproduced (selected clip) can be moved to a desired location by clicking the search key displays 225 and 226. For example, by clicking the search key 226, playback can be executed from the head position of the next selected clip after the currently selected clip.

Thus, the reproduction of the story video is confirmed, and if it is OK, the editing is completed. If there is a part to be further edited, clip selection / deselection on the clip / arrange screen, trimming on the trim / edit screen, clip registration, etc. are performed.
Further, the order of the selected clips may be changed by dragging the selected clip on the story line display 250.

  By the way, when one or more clips are registered from the preview screen or the trim / edit screen described above, when the screen returns to the preview screen, the clip is registered as shown as a clip identification display 255 in FIG. The portions are displayed and expressed in different colors on the bar graph display 204. As a result, the clip registration status can be confirmed on the preview screen.

As described above, the various screen modes including the editing operation method in this example have been described. However, the imaging monitor and setting can be changed by the screen mode in the imaging mode, and the convenience at the time of imaging of the imaging system can be measured. The various screen modes in the editing mode enable various advanced editing processes for the recorded video, and also realize a function as a mobile editing studio.
Needless to say, various GUI editing operations and editing contents can be considered.
