Description

  The present invention relates to a photographing apparatus and method, a reproducing apparatus and method, and a program, and particularly relates to a photographing apparatus and method, a reproducing apparatus and method, and a program that can improve operability.

  Digital video cameras using a touch panel that operates by directly touching the screen with a fingertip, etc., on an LCD (Liquid Crystal Display) panel have become widespread.

  Many of the recent digital video cameras have a function of mounting a plurality of recording media and recording moving images and still images on the mounted recording media. In such a digital video camera, a mode is prepared for each recording medium, and the mode is switched by switching a switch by a user. For example, a digital video camera that records on a magnetic tape and a memory card as a recording medium has a “tape shooting mode” for recording on a magnetic tape and a “memory card shooting mode” for recording on a memory card. These two modes are switched by a switch.

  When the digital video camera is in the “tape shooting mode”, as shown in FIG. 1, the digital video camera includes a button 1a for instructing a review of a moving image (still image) recorded on the magnetic tape and a list of operation items. A button 1c for instructing display of a certain menu screen is displayed on the screen of the LCD panel. When the digital video camera is in the “memory card shooting mode”, as shown in FIG. 2, a button 1b for instructing a review of a still image (moving image) recorded on the memory card, and a button 1c Are displayed on the LCD panel screen.

  That is, in a conventional digital video camera, buttons for functions related to magnetic tape are displayed in the “tape shooting mode”, and buttons for instructing functions related to a memory card are displayed in the “memory card shooting mode”.

  Some digital video cameras have a function of recording moving images and still images on a plurality of recording media in one mode regardless of the mode for each recording medium. For example, a digital video camera that records on a magnetic tape and a memory card as a recording medium, regardless of the modes such as “tape shooting mode” and “memory card shooting mode” as described above, Record moving images and still images on each card.

  In this case, since the digital video camera performs recording in one mode regardless of the recording medium, the buttons 1a to 1c are displayed on the screen of the LCD panel as shown in FIG.

  In other words, in a conventional digital video camera, when recording a moving image or a still image on each of the magnetic tape and the memory card in one mode (regardless of the mode), the function relating to both the magnetic tape and the memory card is instructed. The button to do is displayed.

Further, in the playback mode of the first recording medium, the second recording medium is played back on the condition that the first recording medium is not being played back and the second recording medium is loaded. There is also an imaging device that displays a first icon for this purpose (for example, Patent Document 1). Also, a playback device is known in which an operation unit using on-screen display is provided, and the operation unit corresponds to the type of recording medium (for example, Patent Document 2).

  However, in the touch panel, since the button is arranged on the displayed image, the displayed image may be difficult for the user to hide because the image displaying the button is hidden. There was a problem.

  For example, when taking an image with a conventional digital video camera, the buttons that are not used during shooting, such as the button 1a and the button 1b, hide the image that is being shot, which is difficult for the user to view. There is a possibility that it is difficult to confirm the image.

  In addition, some buttons arranged on the touch panel are unnecessary buttons that are not used by the user, and the display of these buttons may cause discomfort to the user. there were.

  For example, in a conventional digital video camera, when a moving image or a still image is recorded on a plurality of recording media in one mode, buttons for functions related to all the recording media are displayed. Therefore, buttons for instructing functions relating to the recording medium are unnecessary, and displaying these buttons increases the number of buttons, which may be inconvenient.

  Specifically, in a digital video camera that records on a magnetic tape and a memory card, the buttons 1a to 1c are displayed on the screen of the LCD panel. For example, for users who do not use a memory card The button 1b is not necessary, and some users may feel uncomfortable because the button 1b is displayed.

  Furthermore, for example, the imaging device disclosed in Japanese Patent Application Laid-Open No. 2003-8946 records data on each recording medium by separately setting the mode of the first recording medium and the second recording medium. However, as described above, with the development of technology, data is recorded on both the first recording medium and the second recording medium in one mode instead of dividing the mode for each recording medium. In such a case, there is a possibility that the button cannot be displayed optimally in the imaging apparatus that controls the display of the button (icon) for each mode.

The power button 31a is operated, for example, when the user turns on or off the power, and the shooting button 31b is operated, for example, when the user starts or ends shooting.

  The microprocessor 21 executes various processes based on a user operation signal from the operation unit 31. For example, when the user operation signal from the operation unit 31 (power button 31a) instructs the power on, the microprocessor 21 controls the on-screen display circuit 32 so that the power is turned on to the LCD panel 34. The image data of the button (icon) to be displayed is supplied to the superimposing circuit 33.

  The superimposing circuit 33 superimposes image data such as various buttons (icons) supplied from the on-screen display circuit 32 and image data supplied from either the recording / reproducing processing circuit 25 or the recording / reproducing processing unit 29. The image data obtained by superimposing is output to the LCD panel 34 and displayed.

  The LCD panel 34 displays an image corresponding to the image data based on the image data supplied from the superimposing circuit 33. Thereby, for example, an image corresponding to the image data of the subject formed on the light receiving portion of the CCD 23 by the lens 22 is displayed on the screen of the LCD panel 34.

  The LCD panel 34 is configured to include a touch panel 41. The touch panel 41 is configured to pass through the LCD panel 34. The touch panel 41 receives a user's operation for selecting a button (icon) on the operation screen displayed on the screen of the LCD panel 34, and displays position information of the operation position. A signal (hereinafter referred to as a panel operation signal) is supplied to the microprocessor 21.

  The microprocessor 21 executes various processes based on the panel operation signal supplied from the touch panel 41. For example, when the panel operation signal instructs the review of the moving image (still image) recorded on the recording medium 26, the microprocessor 21 controls each of the recording / playback processing circuit 25 and the on-screen display circuit 32. The moving image (still image) recorded on the recording medium 26 is controlled to be displayed on the screen of the LCD panel 34.

  Although illustration is omitted, in the digital video camera 11, a predetermined process is performed on the audio signal captured from the microphone, and the audio data obtained by performing the predetermined process is, for example, It is recorded on the recording medium 26.

  FIG. 5 is a block diagram illustrating a functional configuration example of the digital video camera 11 of FIG.

  The digital video camera 11 is configured to include an operation detection unit 51, an operation determination unit 52, and a display control unit 53.

  In the present embodiment, since the digital video camera 11 has the hardware configuration shown in FIG. 4 described above, the operation detection unit 51, the operation determination unit 52, and the display control unit 53 are, for example, as shown in FIG. Are configured as software (programs) executed by the microprocessor 21. However, by making the hardware configuration of the digital video camera 11 different from the configuration of FIG. 4, the operation detection unit 51, the operation determination unit 52, or the display control unit 53 can be configured as a single hardware, It can also be configured as a combination of software and hardware.

  The operation detection unit 51 detects an operation of the operation unit 31 (for example, the power button 31a, the shooting button 31b, etc.) by the user based on the user operation signal supplied from the operation unit 31. The operation detection unit 51 supplies the detection result to the operation determination unit 52.

  Based on the detection result supplied from the operation detection unit 51, the operation determination unit 52 determines whether various operations such as power on, power off, shooting start, or shooting end have been performed. The operation detection unit 51 supplies the determination result to the display control unit 53.

  The display control unit 53, based on the determination result supplied from the operation determination unit 52, image data such as various buttons (icons) (for example, buttons 71a to 71c described later) and image data of the photographed subject. The display is controlled so that a predetermined screen corresponding to the image data on which and are superimposed is displayed on the screen of the LCD panel 34.

  Next, the operation of the digital video camera 11 will be described. For example, when using the digital video camera 11, the user first turns on the power by pressing the power button 31a, and then presses the shooting button 31b to start shooting the subject. Conversely, when the user stops using the digital video camera 11, first, an operation stop button may be provided separately from the shooting button 31b (of course, separately from the shooting button 31b. For the sake of clarity, it will be described that the shooting can be ended by pressing the shooting button 31b again), and the shooting is ended by pressing the button, and then the power button 31a is pressed to turn off the power. To do.

  Therefore, as an example of processing from when the digital video camera 11 is turned on to when it is turned off at the time of shooting by the user, referring to the flowchart of FIG. 6, the button display at the time of shooting by the digital video camera 11 is shown. Processing will be described.

  The microprocessor 21 causes each unit to execute the processing shown in the flowchart of FIG. 6 when a predetermined operation is instructed by the user via the operation unit 31. At this time, it is assumed that the digital video camera 11 is loaded with a magnetic tape as the recording medium 26 and a memory card as the recording medium 30.

  In step S <b> 11, the operation detection unit 51 detects the operation of the power button 31 a by the user, and supplies the detection result to the operation determination unit 52.

  In step S <b> 12, the operation determination unit 52 determines whether power-on of the digital video camera 11 has been instructed based on the detection result supplied from the operation detection unit 51.

  If it is determined in step S12 that power-on is not instructed, the process returns to step S11 and the above-described processing is repeated. That is, the digital video camera 11 does not operate until the power is turned on by the user.

  On the other hand, if it is determined in step S12 that power-on has been instructed, the process proceeds to step S13, and the display control unit 53 displays a predetermined screen displayed when the power is turned on based on the determination result supplied from the operation determination unit 52. (That is, a screen to be displayed other than during shooting) is displayed on the screen of the LCD panel 34.

  For example, in step S13, the display control unit 53 instructs to review the moving image (still image) recorded on the magnetic tape as shown in FIG. 7 based on the determination result supplied from the operation determination unit 52. A button 71a for performing a review, a button 71b for instructing a review of a still image (moving image) recorded on the memory card, and a button 71c for instructing display of a menu screen which is a list of operation items. The image superimposed on the image is displayed on the screen of the LCD panel 34.

  That is, in the digital video camera 11, when the power is turned on and before shooting is started, the magnetic tape and the memory card are mounted, and the moving image recorded on the magnetic tape is reviewed and recorded on the memory card. Since each of the still image review and menu screen is an effective function (a function that may be operated by the user), each of the buttons 71a to 71c for instructing the operation of these functions is provided. Are displayed on the screen of the LCD panel 34.

  Returning to the flowchart of FIG. 6, in step S <b> 14, the operation detection unit 51 detects the operation of the shooting button 31 b by the user, and supplies the detection result to the operation determination unit 52.

  In step S <b> 15, the operation determination unit 52 determines whether or not an instruction to start shooting is instructed based on the detection result supplied from the operation detection unit 51.

  If it is determined in step S15 that the start of shooting has not been instructed, the process returns to step S14 and the above-described processing is repeated. In other words, the digital video camera 11 stands by in a power-on state until the user presses the shooting button 31b.

  On the other hand, if it is determined in step S15 that the start of shooting has been instructed, the process proceeds to step S16, and the display control unit 53 displays a predetermined screen to be displayed during shooting based on the determination result supplied from the operation determination unit 52. Is displayed on the screen of the LCD panel 34.

  For example, in step S <b> 16, the display control unit 53 displays an image in which the button 71 c is superimposed on the subject image as shown in FIG. 8 on the LCD panel 34 based on the determination result supplied from the operation determination unit 52. Display on the screen.

  That is, in the digital video camera 11, when the power is turned on and shooting is started, the review of the moving image recorded on the magnetic tape and the review of the still image recorded on the memory card are shot. Since the menu screen is a function that is invalid during shooting (a function that may be operated by the user), the menu screen is a function that is invalid during shooting (a function that may be operated by the user). Only the button 71c for instructing the operation is displayed on the screen of the LCD panel 34.

  As described above, the digital video camera 11 displays the button for instructing the operation of the function that is enabled during shooting regardless of the mounted recording medium and mode, and the operation of the function that is disabled during shooting. Since the instruction button is not displayed, the possibility that the image of the subject is hidden by the button during shooting can be reduced.

  Returning to the flowchart of FIG. 6, in step S <b> 17, the operation detection unit 51 detects the operation of the operation button 31 b (operation stop button) by the user, and supplies the detection result to the operation determination unit 52.

  In step S <b> 18, the operation determination unit 52 determines whether or not the end of shooting has been instructed based on the detection result supplied from the operation detection unit 51.

  If it is determined in step S18 that the end of shooting has not been instructed, the process returns to step S17 and the above-described processing is repeated. That is, the digital video camera 11 continues shooting until the user presses the shooting button 31b (operation stop button) again.

  On the other hand, if it is determined in step S18 that the end of shooting has been instructed, the process proceeds to step S19, and the display control unit 53 performs a predetermined display to be displayed at the end of shooting based on the determination result supplied from the operation determination unit 52. A screen (that is, a screen to be displayed other than during shooting) is displayed on the screen of the LCD panel 34.

  For example, in step S19, the display control unit 53 superimposes the buttons 71a to 71c as described above on the subject image based on the determination result supplied from the operation determination unit 52, as shown in FIG. The image is displayed on the screen of the LCD panel 34.

  That is, in the digital video camera 11, when the power is turned on and the photographing is finished, the magnetic tape and the memory card are mounted, and the review of the moving image recorded on the magnetic tape is recorded on the memory card. Each of the still image review and the menu screen is an effective function (a function that may be operated by the user), so that each of the buttons 71a to 71c for instructing the operation of these functions is displayed on the LCD panel. 34 is displayed on the screen.

  Returning to the flowchart of FIG. 6, in step S <b> 20, the operation detection unit 51 detects the operation of the power button 31 a by the user and supplies the detection result to the operation determination unit 52.

  In step S <b> 21, the operation determination unit 52 determines whether power-off is instructed based on the detection result supplied from the operation detection unit 51.

  If it is determined in step S21 that power-off is not instructed, the process returns to step S20 and the above-described processing is repeated. In other words, the digital video camera 11 stands by in a power-on state until the user presses the power button 31a again.

  On the other hand, if it is determined in step S21 that the power-off is instructed, the power of the digital video camera 11 is turned off, and the button display processing at the time of shooting by the digital video camera 11 ends.

  As described above, the digital video camera 11 has no relation to the recording medium (for example, magnetic tape or memory card) and the mode (for example, “tape shooting mode” or “memory card shooting mode”). The display of the buttons displayed on the screen of the LCD panel 34 can be changed.

  In other words, the digital video camera 11 hides a button that indicates an invalid function that cannot be operated at the time of shooting regardless of the recording medium or mode in which it is mounted. It is possible to prevent unnecessary buttons from being displayed on the screen of the panel 34 and hiding an image to be captured by the buttons. As a result, the image to be photographed is less likely to be hidden by the button at the time of photographing, and the user can photograph while sufficiently confirming the image.

  In the above-described example, the button 71c is described as a button displayed on the screen of the LCD panel 34 during shooting, and each of the buttons 71a to 71c is described as a button displayed other than during shooting. The present invention is not limited to this.

  Specifically, each of the button 71a and the button 71b is a button for instructing a function related to a magnetic tape and a memory card that is invalid at the time of photographing, but of course, to designate a function that is invalid at the time of photographing. The button 71c is a button for instructing display of a menu screen that is effective at the time of photographing, but may be a button for instructing other functions that are effective at the time of photographing.

  Further, for example, the button 71a has been described as an example of a button for instructing a function related to the magnetic tape. However, in the present embodiment, the moving image (still image) recorded on the magnetic tape is deleted and a moving image to be shot ( Any button may be used for instructing various functions related to the magnetic tape, such as a change in the recording format and size of the still image), and shooting of a moving image (still image). Similarly, for example, the button 71b has been described as an example of a button for instructing a function related to a memory card. However, in this embodiment, a still image (moving image) recorded on the memory card is deleted and photographed. Any button may be used for instructing various functions related to the memory card, such as changing the recording format and size of a still image (moving image) and capturing a still image (moving image).

  That is, at the time of shooting, the digital video camera 11 displays a button for instructing a function that is valid at the time of shooting, and a button for instructing a function that is invalid at the time of shooting is not displayed. Any may be used.

  By the way, depending on the user who uses a digital video camera to which a plurality of recording media can be mounted, there is a possibility that a recording medium to be used and a recording medium not to be used will appear. Therefore, a method for changing the button display based on whether or not a recording medium is mounted will be described below.

  FIG. 9 is a block diagram showing a configuration of an embodiment of a digital video camera 101 to which the present invention is applied.

  Similarly to the detection unit 111, the detection unit 112 includes a sensor that detects the recording medium 30, and when the recording medium 30 is mounted, a signal indicating that the recording medium 30 has been mounted (hereinafter referred to as second mounting). (Referred to as a signal) is supplied to the microprocessor 21.

  The microprocessor 21 executes various processes based on the second mounting signal supplied from the detection unit 112. For example, when the second operation signal is supplied from the detection unit 112, the microprocessor 21 controls the on-screen display circuit 32 to display a button (icon) on the LCD panel 34 when the recording medium 30 is loaded. Are supplied to the superimposing circuit 33.

  FIG. 10 is a block diagram illustrating a functional configuration example of the digital video camera 101 of FIG.

  The digital video camera 101 is configured to include a recording medium detection unit 121, a recording medium determination unit 122, and a display control unit 123.

  In this embodiment, since the digital video camera 101 has the hardware configuration shown in FIG. 9 described above, the recording medium detection unit 121, the recording medium determination unit 122, and the display control unit 123 include, for example, It is configured as software (program) executed by the microprocessor 21 of FIG. However, the recording medium detection unit 121, the recording medium determination unit 122, or the display control unit 123 can be configured as a single hardware by making the hardware configuration of the digital video camera 101 different from the configuration of FIG. However, it can also be configured as a combination of software and hardware.

  The recording medium detection unit 121 detects the mounting of the recording medium 26 based on the first mounting signal supplied from the detection unit 111. Further, the recording medium detection unit 121 detects the mounting of the recording medium 30 based on the second mounting signal supplied from the detection unit 112. The recording medium detection unit 121 supplies the detection result to the recording medium determination unit 122.

  The recording medium determination unit 122 determines whether or not the recording medium 26 or the recording medium 30 has been removed based on the detection result supplied from the recording medium detection unit 121. Further, the recording medium determination unit 122 determines whether or not the recording medium 26 or the recording medium 30 is loaded based on the detection result supplied from the recording medium detection unit 121. The recording medium determination unit 122 supplies the determination result to the display control unit 123.

  The display control unit 123, based on the determination result supplied from the recording medium determination unit 122, image data such as various buttons (icons) (for example, buttons 141a to 141c described later) and the image of the photographed subject. The display is controlled so that a predetermined screen corresponding to the image data superimposed with the data is displayed on the screen of the LCD panel 34.

  Next, the operation of the digital video camera 101 will be described. When using the digital video camera 101, the user first presses the power button 31a to turn on the power. When the power-on is instructed by the user via the power button 31a, the microprocessor 21 causes each unit to execute button display processing at the time of power-on shown in the flowchart of FIG.

  The digital video camera 101 is appropriately loaded with a magnetic tape as the recording medium 26 and a memory card as the recording medium 30.

  In step S 51, the recording medium detection unit 121 detects the mounting of the magnetic tape, and supplies the detection result to the recording medium determination unit 122.

  In step S <b> 52, the recording medium determination unit 122 determines whether a magnetic tape is attached to the digital video camera 101 based on the detection result supplied from the recording medium detection unit 121.

  If it is determined in step S52 that the magnetic tape is loaded, the process proceeds to step S53, and the display control unit 123 is a predetermined display to be displayed when the magnetic tape is loaded based on the determination result supplied from the recording medium determination unit 122. Is displayed on the screen of the LCD panel 34.

  For example, in step S53, the display control unit 123 reviews the moving image (still image) recorded on the magnetic tape as shown in FIG. 12 based on the determination result supplied from the recording medium determination unit 122. A button 141a for instructing and a button 141c for instructing display of a menu screen which is a list of operation items cause an image superimposed on the image of the subject to be displayed on the screen of the LCD panel 34.

  That is, in the digital video camera 101, when the power is turned on and only the magnetic tape is mounted, the review of the moving image recorded on the magnetic tape and the menu screen are effective functions (operated by the user). The buttons 141a and 141c for instructing the operations of these functions are displayed on the screen of the LCD panel 34.

  Returning to the flowchart of FIG. 11, on the other hand, if it is determined in step S52 that the magnetic tape is not loaded, it is not necessary to display the button 141a, so the process of step S53 is skipped and the process of step S54 is performed. move on.

  In step S <b> 54, the recording medium detection unit 121 detects the attachment of the memory card and supplies the detection result to the recording medium determination unit 122.

  In step S <b> 55, the recording medium determination unit 122 determines whether a memory card is attached to the digital video camera 101 based on the detection result supplied from the recording medium detection unit 121.

  If it is determined in step S55 that a memory card is mounted, the process proceeds to step S56, and the display control unit 123 is a predetermined display that is displayed when the memory card is mounted based on the determination result supplied from the recording medium determination unit 122. Is displayed on the screen of the LCD panel 34, and the button display processing when the power is turned on by the digital video camera 101 is terminated.

  For example, in step S56, the display control unit 123 reviews the still image (moving image) recorded on the memory card as shown in FIG. 13 based on the determination result supplied from the recording medium determination unit 122. Buttons 141b and 141c for instructing display an image superimposed on the image of the subject on the screen of the LCD panel 34.

  That is, in the digital video camera 101, when the power is turned on and only the memory card is attached, the review of the still image recorded on the memory card and the menu screen are effective functions (operated by the user). Therefore, the buttons 141b and 141c for instructing the operation of these functions are displayed on the screen of the LCD panel 34.

  In addition, the display control unit 123 is loaded with both the magnetic tape and the memory card based on the determination result supplied from the recording medium determination unit 122 by the button display process when the power is turned on in FIG. 14, each of the buttons 141 a to 141 c as shown in FIG. 14 causes the image superimposed on the image of the subject to be displayed on the screen of the LCD panel 34.

  That is, in the digital video camera 101, when the power is turned on and both the magnetic tape and the memory card are mounted, a review of a moving image recorded on the magnetic tape or a recording on the memory card is performed. Since the review of the still image and the menu screen are effective functions (functions that may be operated by the user), the buttons 141a to 141c for instructing the operation of these functions are respectively displayed on the LCD panel. 34 is displayed on the screen.

  Returning to the flowchart of FIG. 11, on the other hand, if it is determined in step S55 that the memory card is not inserted, there is no need to display the button 141b, so the processing of step S56 is skipped and the digital video camera 101 Then, the button display processing at power-on is terminated.

  In addition, the display control unit 123 has both the magnetic tape and the memory card mounted based on the determination result supplied from the recording medium determination unit 122 by the button display process at power-on in FIG. If it is determined that there is no image, only the button 141c as shown in FIG. 15 causes the image superimposed on the image of the subject to be displayed on the screen of the LCD panel 34.

  That is, in the digital video camera 101, when the power is turned on and both the magnetic tape and the memory card are not attached, only the menu screen is effective (function that can be operated by the user). Therefore, only the button 141c, which is a button for instructing the operation of the function, is displayed on the screen of the LCD panel 34.

  As described above, in the digital video camera 101, since the button for instructing the function of the recording medium not attached is not displayed, unnecessary buttons are displayed on the LCD panel 34 for confirming the image to be photographed. It is possible to prevent the image to be captured from being hidden by the button.

  For users who use only one of the two recording media (for example, magnetic tape and memory card) that can be mounted, functions relating to the other recording medium (for example, memory card) are used. Button (for example, button 141b) is unnecessary, but in digital video camera 101, the button for instructing the function of the recording medium that is not attached is hidden, so that buttons that are not used are not displayed. can do. As a result, the user is relieved from the discomfort received from the buttons that are not used are always displayed.

  In the above-described example, the buttons 141a and 141c are described as buttons displayed on the screen of the LCD panel 34 when the magnetic tape is mounted, and the buttons 141b and 141c are displayed as buttons displayed when the memory card is mounted. However, the present invention is not limited thereto.

  Specifically, each of the button 141a and the button 141c is a button for instructing a function related to a magnetic tape and a menu that is effective when the magnetic tape is mounted, but of course, other functions that are effective when the magnetic tape is mounted. The button 141b and the button 141c may be buttons for instructing functions related to a memory card and a menu that are valid when the memory card is mounted. Of course, other memory cards may be used. It may be a button for instructing a function that is effective at the time of wearing.

  For example, the button 141a has been described as an example of a button for instructing a function related to the magnetic tape. However, in this embodiment, a moving image (still image) recorded on the magnetic tape is deleted and a moving image (image to be photographed) is captured. Any button may be used for instructing various functions related to the magnetic tape, such as a change in the recording format and size of the still image), and shooting of a moving image (still image). Similarly, for example, the button 141b has been described as an example of a button for instructing a function related to a memory card. However, in this embodiment, a still image (moving image) recorded on the memory card is deleted and photographed. Any button may be used for instructing various functions related to the memory card, such as changing the recording format and size of a still image (moving image) and capturing a still image (moving image).

  That is, when the magnetic tape is mounted, the digital video camera 101 displays a button that indicates a function that is enabled when the magnetic tape is mounted, and a button that indicates a function that is disabled when the magnetic tape is mounted is not displayed. Any button that satisfies these conditions may be used. When the memory card is mounted, the digital video camera 101 displays a button for instructing a function that becomes valid when the memory card is mounted, and hides a button for instructing a function that becomes invalid when the memory card is mounted. Therefore, any button that satisfies these conditions may be used.

  By the way, in the flowchart of FIG. 11 described above, the button display process at the time of power-on has been described. 26 and the recording medium 30 can be attached to the digital video camera 101, and the display of the buttons displayed on the screen of the LCD panel 34 can be controlled.

  Hereinafter, first, the button display process when the magnetic tape is taken out will be described with reference to the flowchart of FIG. 16, and then the button display process when the magnetic tape is mounted will be described with reference to the flowchart of FIG.

  16 and 17, the magnetic tape will be described as an example of the recording medium 26. However, the present invention is not limited to this, and other recording media may be used. For example, the recording medium 30 such as a memory card may be used. However, the same processing is performed. In FIG. 16, it is assumed that a magnetic tape is attached to the digital video camera 101, and that the magnetic tape is not attached to the digital video camera 101 in FIG.

  When the power-on is instructed by the user via the power button 31a and the power of the digital video camera 101 is turned on, the microprocessor 21 performs the button display process when the magnetic tape is taken out as shown in the flowchart of FIG. Let each part execute.

  In step S <b> 71, the recording medium detection unit 121 detects the mounting of the magnetic tape and supplies the detection result to the recording medium determination unit 122.

  In step S <b> 72, the recording medium determination unit 122 determines whether the magnetic tape has been removed from the digital video camera 101 based on the detection result supplied from the recording medium detection unit 121.

  If it is determined in step S72 that the magnetic tape has not been removed, the process returns to step S71 and the above-described processing is repeated. That is, the digital video camera 101 operates according to the user's operation until the magnetic tape is taken out.

  On the other hand, if it is determined in step S72 that the magnetic tape has been taken out, the process proceeds to step S73, and the display control unit 123 selects a magnetic tape review button based on the determination result supplied from the recording medium determination unit 122. A predetermined non-display screen is displayed on the screen of the LCD panel 34, and the button display processing when the digital tape is taken out by the digital video camera 101 is finished.

  For example, in step S73, the display control unit 123, based on the determination result supplied from the recording medium determination unit 122, the moving image recorded on the magnetic tape as shown in FIG. A button 141a for instructing a review of (still image) causes an image not superimposed on the subject screen to be displayed on the screen of the LCD panel 34.

  Specifically, in the digital video camera 101, when both the magnetic tape and the memory card are mounted, each of the buttons 141a to 141c as shown in FIG. The superimposed image is displayed on the screen of the LCD panel 34. At this time, when the user removes the magnetic tape, the button 141b and the button 141c as shown in FIG. The image superimposed on is displayed on the screen of the LCD panel 34.

  Further, in the digital video camera 101, when only the magnetic tape is attached, the image in which the button 141a and the button 141c described above are superimposed on the subject image as shown in FIG. When the magnetic tape is taken out by the user at this time, only the button 141c as shown in FIG. 15 described above is displayed on the screen of the LCD panel 34. Will be displayed.

  In other words, in the digital video camera 101, when the power is turned on and the magnetic tape is taken out, the review of the moving image (still image) recorded on the magnetic tape is invalid (possibly operated by the user). Therefore, the button 141a for instructing the operation of the function is not displayed on the screen of the LCD panel 34.

  In addition, when the user is instructed to turn on the power via the power button 31a and the power of the digital video camera 101 is turned on, the microprocessor 21 displays a button display when the magnetic tape is mounted as shown in the flowchart of FIG. Cause each part to execute processing.

  In step S 91, the recording medium detection unit 121 detects the mounting of the magnetic tape and supplies the detection result to the recording medium determination unit 122.

  In step S <b> 92, the recording medium determination unit 122 determines whether a magnetic tape is attached to the digital video camera 101 based on the detection result supplied from the recording medium detection unit 121.

  If it is determined in step S92 that the magnetic tape is not loaded, the process returns to step S91 and the above-described processing is repeated. That is, the digital video camera 101 operates in accordance with the user operation until the magnetic tape is loaded.

  On the other hand, if it is determined in step S92 that the magnetic tape has been loaded, the process proceeds to step S93, and the display control unit 123 selects a magnetic tape review button based on the determination result supplied from the recording medium determination unit 121. The predetermined screen being displayed is displayed on the screen of the LCD panel 34, and the button display processing when the magnetic tape is loaded by the digital video camera 101 is terminated.

  For example, in step S93, the display control unit 123, based on the determination result supplied from the recording medium determination unit 121, the moving image recorded on the magnetic tape as shown in FIG. A button 141a for instructing a review of (still image) causes an image superimposed on the screen of the subject to be displayed on the screen of the LCD panel 34.

  Specifically, in the digital video camera 101, when both the magnetic tape and the memory card are not attached, the above-described image in which only the button 141c as shown in FIG. 15 is superimposed on the subject image. Is displayed on the screen of the LCD panel 34. At this time, when the magnetic tape is loaded by the user, the buttons 141a and 141c as described above are superimposed on the image of the subject as shown in FIG. The displayed image is displayed on the screen of the LCD panel 34.

  In addition, in the digital video camera 101, when only the memory card is attached, the image in which the button 141b and the button 141c described above are superimposed on the subject image as shown in FIG. In this case, when the magnetic tape is loaded by the user, an image in which each of the buttons 141a to 141c described above is superimposed on the image of the subject as shown in FIG. 14 is displayed on the LCD. It is displayed on the screen of the panel 34.

  In other words, in the digital video camera 101, when the power is turned on and the magnetic tape is loaded, a function (possibility of being operated by the user) that enables the review of moving images (still images) recorded on the magnetic tape is effective. Therefore, a button 141a for instructing the operation of the function is displayed on the screen of the LCD panel 34.

  Thus, in the digital video camera 101, regardless of the recording medium (for example, magnetic tape, memory card, etc.) and the mode (for example, “tape shooting mode”, “memory card shooting mode”, etc.) attached, The display of the buttons displayed on the screen of the LCD panel 34 can be changed depending on whether or not the recording medium is attached.

  That is, in the digital video camera 101, a button for instructing a function related to a recording medium when the recording medium is not mounted, depending on whether the recording medium is mounted, regardless of the recording medium and mode mounted. Since it is hidden, it is possible to prevent unnecessary buttons from being displayed. As a result, for example, when a user who does not use a memory card does not insert the memory card, the button 141b for instructing functions related to the memory card is not displayed on the screen of the LCD panel 34. Can be used.

  As described above, in the flowcharts of FIGS. 16 and 17, the processing at the time of taking out and attaching the magnetic tape (recording medium 26) has been described. The same processing is performed for the above processing.

  By the way, in the above-described example, the display of the buttons displayed on the screen of the LCD panel 34 is controlled depending on whether the digital video camera 11 is shooting. However, the digital video camera 11 is controlled by a magnetic tape or a memory card. Even when image data recorded on the LCD panel 34 is reproduced, the display of buttons displayed on the screen of the LCD panel 34 can be controlled similarly. Hereinafter, button display during reproduction will be described with reference to FIGS.

  For example, when the digital video camera 11 is before reproducing the image data recorded on the magnetic tape, as shown in FIG. 18, the button 161a for instructing the reproduction of the image data recorded on the memory card. , A button 161a ′ for performing settings relating to the memory card such as a memory card format and size change, a button 161b for instructing rewinding of an image to be reproduced, a button 161c for instructing reproduction of an image, and an image to be reproduced A button 161d for instructing fast-forwarding of the menu and a menu button 161e for instructing display of a menu screen which is a list of operation items are displayed on the screen of the LCD panel 34, respectively.

  Here, when the user gives an instruction to reproduce the image data recorded on the magnetic tape via the button 161c, and the image is reproduced, the digital video camera 11 displays the buttons 161b to 161e as shown in FIG. In addition to the button 161a for instructing the reproduction of the image data recorded on the memory card and the button 161a 'for performing the setting relating to the memory card, the button 161f for instructing the stop of the image being reproduced Are displayed on the screen of the LCD panel 34.

  That is, in the digital video camera 11, when the image data recorded on the magnetic tape is reproduced, the function of reproducing and setting the image data recorded on the memory card is invalid (possibly operated by the user). Therefore, instead of the button 161a and the button 161a ′, a button 161f for instructing to stop the image being reproduced is displayed on the screen of the LCD panel 34.

  Thus, in the digital video camera 11, regardless of the recording medium (for example, magnetic tape or memory card) and the mode (for example, “tape shooting mode”, “memory card shooting mode”, etc.) attached, It is possible to hide a button for instructing a function that becomes invalid during reproduction. As a result, since the buttons that cannot be used are not displayed, the user can use the digital video camera 11 more comfortably.

  As described above, according to the present invention, operability can be improved.

  Further, according to the present invention, when taking a picture with a digital video camera, it is possible to hide a button for instructing a function that becomes invalid during the taking regardless of the recording medium and the mode. As a result, since the displayed image is easy to see, the user can shoot more reliably while checking the captured image.

  Furthermore, according to the present invention, it is possible to hide a button for instructing a function relating to a recording medium not attached to the digital video camera regardless of the recording medium or mode. As a result, the user can operate the digital video camera more comfortably because only the buttons for instructing the function to be used are displayed.

  In the above-described example, the two recording media of the magnetic tape and the memory card have been described. However, the present invention is not limited to this, and the present invention can also be applied to a case where three or more recording media are mounted. Further, the above-described “power off” includes not only mechanical off but also suspend and sleep states.

  The series of processes described above can be executed by hardware or can be executed by software. When a series of processing is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a program recording medium in a general-purpose personal computer or the like.

  FIG. 20 is a block diagram showing an example of the configuration of a personal computer that executes the above-described series of processing by a program. A CPU (Central Processing Unit) 211 executes various processes according to a program recorded in a ROM (Read Only Memory) 212 or a recording unit 218. A RAM (Random Access Memory) 213 appropriately stores programs executed by the CPU 211 and data. These CPU 211, ROM 212, and RAM 213 are connected to each other by a bus 214.
