<Digital camera configuration>
FIG. 1 is a diagram for explaining a configuration of a digital camera which is an example of a data processing device according to the first embodiment of the present invention. FIG. 1A is a block diagram showing the configuration of the digital camera, and FIG. 1B is a perspective view showing the appearance of the digital camera from the front with the display unit expanded upward. Further, FIG. 1C is a perspective view showing the appearance of the digital camera from the front with the display unit expanded to the right.

Although a digital camera (hereinafter, simply referred to as a camera) will be described here as an example of a data processing device, the data processing device is not limited to the camera. For example, the data processing device may be a so-called smart device such as a portable media player or a smartphone, and an information processing device such as a personal computer.

First, with reference to FIG. 1A, the camera 100 has a control unit 101. The control unit 101 controls the entire camera 100 according to the input signal and the program described later. Instead of the control unit 101 controlling the entire device, a plurality of hardware may share the processing to control the entire camera 100.

The image pickup unit 102 includes, for example, an optical lens unit and an image pickup element, and the optical lens unit is provided with at least an aperture, a zoom lens, and a focus lens. Then, an optical image (subject image) is formed on the image pickup element via the optical lens unit, and the image pickup element converts it into an electric signal (video signal) corresponding to the optical image.

The image pickup unit 102 performs noise reduction processing or the like on the electric signal under the control of the control unit 101, and then outputs image data which is digital data by A / D conversion. The control unit 101 temporarily stores the image data in the buffer memory. Then, the control unit 101 performs a predetermined process on the image data stored in the buffer memory and records it on the recording medium 107.

The non-volatile memory 103 is a non-volatile memory that can be electrically erased and recorded, and the non-volatile memory 103 stores a program or the like executed by the control unit 101. The working memory 104 is used as a buffer memory for temporarily holding the image data obtained by the imaging unit 102. Further, the working memory 104 is used as an image display memory and a working area of the control unit 101 when displaying an image on the display unit 106.

The operation unit 105 is operated by the user, and the user inputs an instruction to the camera 100 using the operation unit 105. The operation unit 105 is provided with, for example, a power button for turning on / off the power of the camera 100, a release switch for instructing shooting, and a zoom lever for instructing a zoom operation.

Further, the operation unit 105 is provided with a playback button for instructing the reproduction of image data and a mode dial for instructing the activation mode of the camera 100. In addition, the operation unit 105 includes a dedicated connection button for starting communication with an external device by the communication unit 111, which will be described later, and a touch panel formed on the display unit 106.

The release switch has a first switch SW1 and a second switch SW2. When the release switch is in the so-called half-pressed state, the first switch SW1 is turned on. As a result, the control unit 101 starts shooting preparations such as AF (autofocus) processing, AE (autoexposure) processing, AWB (auto white balance) processing, and EF (flash pre-flash) processing. Further, when the release switch is in the so-called fully pressed state, the second switch SW2 is turned on. As a result, the control unit 101 starts shooting.

The viewfinder image is displayed on the display unit 106 at the time of shooting. Further, on the display unit 106, an image corresponding to the image data obtained by shooting is displayed, and characters and the like are displayed for interactive operation.

The display unit 106 does not necessarily have to be built in the camera 100. The camera 100 may be connected to an internal or external display unit 106, and the display unit 106 may at least have a display control function for controlling the display.

The image data obtained by the imaging unit 102 is recorded on the recording medium 107. The recording medium 107 is removable from or built into the camera 100. That is, the camera 100 may be provided with at least a means for accessing the recording medium 107.

A battery 108 is attached to the camera 100, and the battery 108 supplies the electric power required to operate the camera 100. The battery 108 may be attached to and detached from the camera 100, or may be built into the camera 100. That is, the battery 108 only needs to be able to supply power to at least the camera 100.

The communication unit 111 is an interface for connecting the camera 100 to an external device. The illustrated camera 100 transmits and receives various data such as image data to and from an external device by the communication unit 111. For example, the control unit 101 transmits the image data obtained by the image pickup unit 102 to an external device by the communication unit 111. Here, the communication unit 111 has an interface for communicating with an external device, for example, by a so-called wireless LAN according to the standard of IEEE802.11.

The short-range wireless communication unit 112 includes, for example, an antenna, a modulation / demodulation circuit for processing a wireless signal, and a communication controller. The short-range radio communication unit 112 outputs a modulated radio signal from the antenna and demolishes the radio signal received by the antenna to perform short-range radio according to the IEEE802.15 standard (so-called Bluetooth®). Communicate.

The communication by Bluetooth has a narrow communication range (that is, a short communication distance) as compared with wireless LAN communication. Further, the communication speed by Bluetooth is slower (that is, slower) than the wireless LAN communication. On the other hand, communication by Bluetooth consumes less power than wireless LAN communication. In the illustrated example, version 4.0 of Bluetooth Low Energy (BLE: registered trademark), which has low power consumption, is used for communication by Bluetooth.

In the illustrated camera 100, the control unit 101 can send and receive various data such as image data to and from an external device by the short-range wireless communication unit 112. For example, upon receiving a shooting instruction sent from an external device, the control unit 101 controls the imaging unit 102 to perform shooting. Further, when receiving an instruction for transmitting / receiving data by wireless LAN communication, the control unit 101 controls communication 111 and starts communication by wireless LAN.

Subsequently, with reference to FIGS. 1 (b) and 1 (c), the image pickup unit 102 is arranged on the front side of the camera 100, and the release unit 105 is one of the operation units 105 on the upper surface of the camera 100. The switch is placed. A display unit 106 is arranged on the back side of the camera 100, and the display unit 106 refers to the camera 100 with the upper end portion (see FIG. 1B) or the right end portion (see FIG. 1C) of the camera 100 as an axis. It is rotatable. That is, the position of the display unit 106 with respect to the camera 100 is variable.

For example, when the photographer shoots a subject that does not include the photographer himself, the display unit 106 is closed. The state in which the display unit 106 is closed means a state in which the imaging direction (direction) of the imaging unit 102 and the display direction (that is, the display surface) of the display unit 106 are opposite to each other. As a result, the photographer can take a picture while checking the live image displayed on the display unit 106.

On the other hand, when the photographer shoots a subject including the photographer himself (including the case where only the photographer himself is photographed), the display unit 106 is kept open. The state in which the display unit 106 is opened means a state in which the imaging direction of the imaging unit 102 and the display direction of the display unit 106 are in the same direction. As a result, the photographer can shoot a subject including the photographer himself while checking the live image displayed on the display unit 106. By connecting the display unit 106 to the camera 100 in a rotatable manner in this way, the photographer can perform shooting while always checking the live image.

The wide button 309 is a button used when controlling the image pickup unit 102 to the wide side, and the telebutton 310 is a button used when controlling the image pickup unit 102 to the telephoto side. Then, when the buttons 307 to 310 are selected, the control unit 201 transmits a control command corresponding to the selection to the camera 100 by BLE communication.

<Shooting remote control processing>
FIG. 4 is a flowchart for explaining a shooting process performed by the camera shown in FIG. Hereinafter, this process may be referred to as a shooting remote control process.

The process according to the illustrated flowchart is performed by the control unit 101 provided in the camera 100 controlling the camera 100 according to the input signal and the program. Further, unless otherwise specified, the same applies to other flowcharts showing the processing of the camera 100.

When the user operates the operation unit 105 to shift the camera 100 to the shooting state, the camera 100 starts the shooting process. First, in step S401, the control unit 101 detects the orientation (that is, rotation) of the display unit 106. As described with reference to FIGS. 1 (b) and 1 (c), the display unit 106 is rotatable around the end of the housing of the camera 100, and the display unit 106 can be rotated and opened. That is, the user can keep the display unit 106 open or closed.

If the control unit 101 determines that the display unit 106 is in the open state, the process proceeds to step S402. On the other hand, when the control unit 101 determines that the display unit 106 is in the closed state. The process proceeds to step S404.

In step S402, the control unit 101 determines whether or not the smart device 200 is in BLE connection by the short-range wireless communication unit 112. If the control unit 101 determines that the BLE connection is in progress, the process proceeds to step S403. On the other hand, if the control unit 101 determines that the BLE connection is not in progress, the process proceeds to step S404.

In step S403, the control unit 101 displays a message on the display unit 106 indicating that the photographing remote controller can be used. In step S403, the control unit 101 may transmit the message to the smart device 200 by BLE communication by the short-range wireless communication unit 112. At least one of displaying a message indicating that the photographing remote controller can be used on the display unit 106 and transmitting the message to the smart device 200 by BLE communication by the short-range wireless communication unit 112 is executed. That is, both may be executed. After that, the process proceeds to step S404.

FIG. 5 is a diagram for explaining an example of a screen displayed on a camera and a smart device in the shooting process shown in FIG. 5 (a) is a diagram showing an example of a screen displayed on the smart device, and FIG. 5 (b) is a diagram showing another example of the screen displayed on the smart device. Further, FIG. 5 (c) is a diagram showing still another example of the screen displayed on the smart device, and FIG. 5 (d) is a diagram showing another example of the screen displayed on the camera.

In the process of step S403, the control unit 101 displays the message 504 shown in FIG. 5D on the display unit 106. When the control unit 201 receives a message from the short-range wireless communication unit 212, the control unit 201 displays a message on the display unit 206 indicating that the shooting remote controller can be used.

FIG. 5A shows an example of a message displayed on the display unit 206 when a message is received from the camera 100 when the smart device 200 is in the locked state. Here, a message 501 indicating that the shooting remote controller can be used is displayed in the notification area of the lock screen.

When the user selects message 501, the control unit 201 activates the shooting remote control application and displays the shooting remote control application screen shown in FIG. 3C on the display unit 206.

FIG. 5B shows an example of a message displayed on the display unit 206 when a message is received from the camera 100 when the lock of the smart device 200 is released. Here, a message 502 indicating that the shooting remote controller can be used is displayed in the notification area of the home screen. When the user selects "Yes" in the message 502, the control unit 201 activates the shooting remote control application and displays the shooting remote control application screen shown in FIG. 3C on the display unit 206.

FIG. 5C shows the display on the display unit 206 when a message is received from the camera 100 when the smart device 200 is not in the mode of activating the application that communicates with the camera 100 and using the shooting remote controller. An example of the message is shown. Here, a message 503 indicating that the shooting remote controller can be used is displayed in the notification area on the application. When the user selects "Yes" in the message 503, the control unit 201 activates the shooting remote control application and displays the shooting remote control application screen shown in FIG. 3C on the display unit 206.

In this way, when the display unit 106 is open in the camera 100 and the camera 100 and the smart device 200 are in BLE connection, a message indicating that the shooting remote controller can be used for the camera 100 or the smart device 200. Is displayed. This encourages the user to use the shooting remote control function.

In the illustrated example, the camera 100 and the smart device 200 are always BLE-connected. Therefore, when the display unit 106 is opened to shoot the user himself / herself, the user can know that the shooting remote controller can be used, which improves the convenience of the user.

Further, when the smart device 200 is notified of the message, the message is displayed according to the state of the smart device 200 as described with reference to FIGS. 5 (a) to 5 (c). Then, when the user selects any of the notification messages 501 to 503, the screen shown in FIG. 3C is displayed and the shooting remote controller can be used.

When a message is transmitted to the smart device 200, the message may be displayed on the display unit 206 and a notification sound may be sounded to notify the user of the reception of the message. Alternatively, the smart device 200 may control a vibrating unit (not shown) and notify the user of the reception of the message by vibrating. With reference to FIG. 4 again, in step S404, the control unit 101 determines whether or not the operation unit 105 is operated by the user to give a shooting instruction. If the control unit 101 determines that the shooting instruction has been given, the process proceeds to step S406. On the other hand, if the control unit 101 determines that the shooting instruction is not given, the process proceeds to step S405.

In step S405, the control unit 101 determines whether or not a shooting instruction has been given by the smart device 200 (that is, the opposite device) by BLE communication. When the user selects the shooting button 307 on the shooting remote control application screen, the control unit 201 transmits a shooting command to the camera 100 by the short-range wireless communication unit 212. Then, when the short-range wireless communication unit 112 receives the shooting command, the control unit 101 determines that the shooting instruction has been executed by the smart device 200.

If the control unit 101 determines that the smart device 200 has given a shooting instruction, the process proceeds to step S406. On the other hand, when the control unit 101 determines that there is no shooting instruction from the smart device 200, the process returns to step S401.

In step S406, the control unit 101 controls the imaging unit 102 to perform a shooting process. Then, in step S407, the control unit 101 determines whether or not the operation unit 105 is operated by the user and the shooting is completed. When the control unit 101 determines that the shooting is completed, the shooting process (that is, the shooting mode) is finished. On the other hand, when the control unit 101 determines that the shooting is not completed, the process returns to step S401.

As described above, in the embodiment of the present invention, the camera 100 is always connected to the smart device 200 by BLE. Then, when the determination result that the user has opened the display unit 106 of the camera 100 in an attempt to photograph himself / herself is obtained, the photographing remote controller can be used for the display unit 106 of the camera 100 or the display unit 206 of the smart device 200. Let me know that there is. As a result, the user can easily know that remote control shooting is possible in a situation where remote control such as remote control shooting is useful.

[Second Embodiment]
Subsequently, an example of the camera and the smart device according to the second embodiment of the present invention will be described. The configuration of the camera and smart device according to the second embodiment is the same as that of the camera and smart device shown in FIG.

FIG. 6 is a diagram showing an example of a shooting mode selection screen displayed on the display unit in the camera according to the second embodiment of the present invention.

Shooting modes include, for example, auto mode (Auto), program AE (P), aperture priority AE (Av), shutter speed priority AE (Tv), and manual exposure (M), and further shoot the user himself. There is a self-portrait mode 601.

Here, the camera 100 and the smart device 200 are always connected by BLE. Then, when the user operates the operation unit 105 of the camera 100 to select the self-shooting mode 601, the user is notified that the shooting remote controller can be used.

In the illustrated flowchart, the same steps as those in the flowchart shown in FIG. 4 are designated by the same reference numerals and the description thereof will be omitted.

When the user operates the operation unit 105 to shift the camera 100 to the shooting state, the camera 100 starts the shooting process. In step S701, the control unit 101 determines whether the display unit 106 is rotated and opened, or whether the self-shooting mode is selected as the shooting mode. When the control unit 101 determines that the display unit 106 is in the open state or the self-shooting mode is selected, the process proceeds to S402. On the other hand, if the control unit 101 determines that the display unit 106 is not in the open state and the self-shooting mode is not selected, the process proceeds to step S703.

If the control unit 101 determines in step S402 that the BLE connection is not in progress, the process proceeds to step S703. On the other hand, if the control unit 101 determines that the BLE connection is in progress, the process proceeds to step S702.

In step S703, the control unit 101 sets the displayed flag to FALSE. The displayed flag is a variable stored in the working memory 104. The displayed flag is a flag indicating whether or not a message indicating that the shooting remote controller can be used has been displayed on the camera 100 or the smart device 200. After that, the control unit 101 proceeds to the process of step S404.

In step S702, the control unit 101 determines whether or not the displayed flag stored in the working memory 104 is FALSE. When the control unit 101 determines that the displayed flag is FALSE, the process proceeds to step S403 described above. On the other hand, if the control unit 101 determines that the displayed flag is not FALSE, the process proceeds to step S404.

By such processing, for example, when it is detected that the display unit 106 has been opened once, the control unit 101 displays a message that the shooting remote controller can be used, and then the self-shooting mode is selected, The message will not be displayed again. Then, it is not necessary to display the message in step S403 until the condition for displaying the message is released.

After performing the process of step S403, in step S706, the control unit 101 sets the displayed flag stored in the working memory 104 in TRUE. Then, the control unit 101 proceeds to the process of step S404.

If the control unit 101 determines in step S405 that there is no shooting instruction from the smart device 200, the process returns to step S701. Similarly, if the control unit 101 determines in step S407 that the photographing is not completed, the process returns to step S701.

As described above, in the second embodiment of the present invention, when the camera 100 and the smart device 200 are connected by BLE, when the display unit 106 of the camera 100 is opened or the self-shooting mode is set, shooting is performed. A message is displayed stating that the remote control is available. As a result, it is possible to encourage the user who uses the camera 100 or the smart device 200 to use the shooting remote control function. That is, the BLE connection is always maintained between the camera 100 and the smart device 200. Therefore, when the user opens the display unit 106 of the camera 100 to shoot himself or selects the self-shooting mode, the user can know that the shooting remote controller can be used. , User convenience is improved.

Further, when the message is notified to the smart device 200, the notification is performed according to the state of the smart device 200 as described with reference to FIGS. 5 (a) to 5 (c). Then, when the user selects any of these messages 501 to 503, the shooting remote control application screen (operation screen) shown in FIG. 3C is displayed, and the user can easily give a shooting instruction.

In the first embodiment, an example of notifying the user that the shooting remote controller can be used when the display unit 106 of the camera 100 is opened has been described. In the second embodiment, an example of notifying the user that the shooting remote controller can be used even when the self-shooting mode is set has been described. When the user takes a picture of himself / herself, if the operation unit of the camera 100 is operated, the user's hand may be taken. In order to prevent such a situation, it is useful to use a shooting remote controller. Therefore, if the user is notified that the shooting remote controller can be used and the user is notified that the shooting remote controller can be used, the convenience of the user can be improved.

There are other cases where it is convenient to use the shooting remote control. For example, a specific shooting mode or shooting condition other than the self-shooting mode, such as bulb shooting (bulb shooting mode) or time-lapse shooting (timer shooting mode) to prevent camera shake, and shooting in the zoomed state. In this case, the user may be notified in the same manner that the shooting remote controller can be used.

In the first and second embodiments described above, the message is notified according to the state change of the camera 100 (for example, the display unit 106 is opened or the selfie mode is set) regardless of the state of the smart device 200. I did. That is, in the smart device 200, for example, the camera 100 notifies the smart device 200 of a message even if another application is running. Then, it is determined whether or not to display the message on the smart device 200.

On the other hand, the state change of the smart device 200 may be notified to the camera 100 in advance, and the camera 100 may determine whether or not to notify the message according to the state of the smart device 200. For example, if the shooting remote control application has already been started in the smart device 200, the camera 100 is notified to that effect. Then, based on the notification from the smart device, the camera 100 does not notify the message even when the shooting remote controller becomes available.

Further, even if the state change occurs in the camera 100, the camera 100 may notify the message when the state change continues for a predetermined time without notifying the message immediately. This is done for the following reasons. That is, the rotatable monitor is provided with two axes at the connection portion with the main body of the camera 100, and is folded with the screen exposed to the outside and the screen faces inward and the back of the display is external. Some can be folded while exposed to the camera. This is because when trying to change from the latter state to the former state on such a monitor, it is considered that the user has no intention of taking a selfie even if the screen is oriented in the same direction as the image pickup unit. ..
