Description

  The present invention relates to an information processing apparatus that can communicate with an imaging apparatus, a control method thereof, and a program, and more particularly to an information processing apparatus for performing display based on a shooting state of the imaging apparatus, a control method thereof, and a program.

  Conventionally, when an imaging device has a moving image shooting mode and a still image shooting mode and switches between these modes, shooting parameters effective for still image shooting and parameters effective for movie shooting are displayed in different areas on the screen. The technique of displaying on is known. This makes it easy for the user to understand the shooting parameters (see, for example, Patent Document 1).

  On the other hand, digital cameras equipped with a wireless communication function are increasing in recent years. In such a digital camera, a live view image is transmitted and displayed on an information processing apparatus connected wirelessly, and the digital camera is controlled from the information processing apparatus so that still image shooting or moving image shooting can be performed seamlessly. (Hereinafter referred to as “remote shooting”).

JP 2006-74321 A

  However, in the case of remote shooting, unlike the case of Patent Document 1, the information processing device, not the imaging device, switches between the moving image shooting mode and the still image shooting mode. Therefore, at the start of remote shooting, the information processing apparatus needs to acquire all the parameters related to still image shooting and shooting parameters related to moving image shooting from the imaging device.

  On the other hand, if all the acquired shooting parameters are displayed on the information processing apparatus at the start of remote shooting, a large display area is required. In particular, when the information processing apparatus is a device such as a smartphone whose display area is not so large, an unnecessary increase in the area is not desirable.

  In addition, as a result of an erroneous operation such as the user accidentally changing the setting for a shooting parameter that is not suitable for the intended shooting, the shooting intended by the user may not be performed or unnecessary trouble may occur. Or

  An object of the present invention is to provide an information processing apparatus, a control method thereof, and a program capable of suppressing an imaging parameter display area and preventing a user's erroneous operation on an imaging parameter when instructing an imaging apparatus to perform remote imaging. It is to provide.

  According to a first aspect of the present invention, an information processing apparatus performs either still image shooting or moving image shooting in response to an instruction from a user during display of a live view image from an imaging apparatus to an imaging apparatus that performs wireless communication. In the information processing apparatus that performs one remote shooting, a first acquisition unit that acquires all setting values of shooting parameters from the imaging device without distinguishing between moving image related parameters and still image related parameters, a still image shooting view, and a moving image shooting view Setting means for setting one of the two views as a view setting value, and when the set view setting value is the still image shooting view, setting values of shooting parameters useful for still image shooting among the acquired shooting parameters And a first display control means for controlling to hide the setting value of the shooting parameter that is not useful for the still image shooting, and the setting If the obtained view setting value is the moving image shooting view, the setting value of the shooting parameter useful for moving image shooting among the acquired shooting parameters is displayed, and the setting value of the shooting parameter not useful for moving image shooting is not displayed. And a second display control unit configured to perform control, and the setting unit is set as an initial value of the still image shooting view and the moving image shooting view when receiving the remote shooting start request from the user. The set view is set as the view setting value.

  According to the present invention, when remote imaging is instructed to the imaging apparatus, it is possible to suppress the display area of the imaging parameter and to prevent a user's erroneous operation on the imaging parameter.

  In the present embodiment, the digital camera 100 and the mobile phone 200 communicate directly without passing through other access points. That is, the digital camera 100 forms a wireless LAN network as a simple access point. When the digital camera 100 operates as a simple access point, the digital camera 100 starts to periodically transmit a beacon signal. The mobile phone 200 detects the beacon signal and participates in the wireless LAN network formed by the digital camera 100. The digital camera 100 and the mobile phone 200 are ready to transmit and receive data (establish communication between the devices) through mutual device discovery, device capability acquisition, and the like.

  The communication method between the digital camera 100 and the mobile phone 200 is not limited to the above. For example, a communication method such as an infrastructure mode in which the digital camera 100 and the mobile phone 200 participate in a network formed by an external access point and perform communication on the network may be used. In addition, the digital camera 100 and the mobile phone 200 communicate with each other via a wireless LAN, but may communicate with, for example, Bluetooth.

<Remote shooting function with remote control application>
When the communication between the digital camera 100 and the mobile phone 200 is established, the user can control the digital camera 100 and perform shooting on a remote control application that operates on the mobile phone 200. Hereinafter, this is referred to as remote shooting. In the remote shooting, it was confirmed by the mobile phone 200 that the digital camera 100 can perform live view, moving image shooting, still image shooting, and wireless data communication from the device identification data transmitted from the digital camera 100. Is the premise.

  Below, the outline | summary of the remote control application which operate | moves on the mobile telephone 200 is demonstrated.

  In the remote control application activated on the mobile phone 200, a live view image display and GUI transmitted from the digital camera 100 are displayed on the display unit 206. When the user operates each GUI, it is possible to control still image shooting and moving image shooting with the digital camera 100 and change settings of various shooting parameters.

  One of the still image shooting button and the moving image shooting button can be switched in the GUI display of the remote control application, and if the button is pressed while the live view image is displayed, the digital camera 100 is requested to shoot. Is issued. The pressing of the still image shooting button corresponds to the operation of the release switch 105a of the digital camera 100. The pressing of the moving image shooting button corresponds to the operation of the recording switch 105 f of the digital camera 100.

  When the digital camera 100 receives a still image shooting request or a moving image shooting request, the digital camera 100 performs various processes according to the shooting setting state, and performs still image shooting or moving image shooting. That is, during remote shooting, the digital camera 100 does not switch between the moving image shooting mode and the still image shooting mode, and can perform moving image shooting or still shooting from the live view state in response to a shooting request from the mobile phone 200. Start one of the image captures seamlessly.

  In addition, when the digital camera 100 starts communication with the mobile phone 200, the digital camera 100 stores various setting information (current setting values and a list of currently settable values) related to shooting such as a shooting mode and shooting parameters. Notify Thereafter, every time the setting information changes, the setting information is notified from the digital camera 100 to the mobile phone 200. Hereinafter, this notification is referred to as an imaging parameter change notification.

  Furthermore, by transmitting various shooting parameter change requests from the mobile phone 200 to the digital camera 100, various shooting parameters of the digital camera 100 can be changed.

  Hereinafter, processing of the digital camera 100 and the mobile phone 200 when performing remote shooting will be described with reference to FIG.

  FIG. 3 is a sequence diagram illustrating operations of the digital camera 100 and the mobile phone 200 when performing remote shooting.

  The procedure of FIG. 3 is started in a state where the digital camera 100 and the mobile phone 200 are connected in advance via a wireless LAN. Further, the mobile phone 200 is in a state where a remote control application for remotely controlling the digital camera 100 is activated.

  First, at T301, for example, the user inputs an instruction to perform remote shooting by an operation of selecting a remote shooting function displayed on the menu of the remote control application.

  In response to the input of the instruction at T301, at T302, the mobile phone 200 notifies the digital camera 100 of a remote shooting start request.

  In response to this, at T303, the digital camera 100 starts the remote shooting function.

  On the other hand, in response to the input of the instruction in T301, the mobile phone 200 starts displaying a remote shooting screen for performing remote shooting on the display unit 206 in T304. Note that on the remote shooting screen, a GUI display for displaying live view images, controlling still image shooting, moving image shooting, and changing various shooting parameter settings is performed.

  Also, at T305, the digital camera 100 transmits a shooting parameter change notification for notifying the mobile phone 200 of setting information of various shooting parameters such as a shooting mode, an aperture value, and a shutter speed for each shooting parameter. . Note that every time the setting information of the shooting parameters is changed in the digital camera 100, a shooting parameter change notification is sent from the digital camera 100 to the mobile phone 200. Here, the setting information of the various shooting parameters in the present embodiment includes a set value at that time and a list of values that can be changed by remote shooting at that time.

  In addition, during execution of remote shooting, the digital camera 100 periodically transmits a live view image to the mobile phone 200 at T306. Depending on the protocol of communication between the digital camera 100 and the mobile phone 200, the live view image is continuously received by repeatedly requesting the live view image from the mobile phone 200 to the digital camera 100. The mobile phone 200 displays the received live view image on the display unit 206. As a result, the user of the mobile phone 200 can check the subject in remote shooting as well as the operation of the digital camera 100, and can check the composition and hue, the shutter chance, and the start timing of moving image shooting. It becomes.

  Thereafter, for example, when the user instructs the mobile phone 200 to change the shooting parameter at T307, the mobile phone 200 transmits a shooting parameter change request to the digital camera 100 at T308. In response to this change request, at T309, the digital camera 100 changes the setting value of the designated shooting parameter. At T310, a shooting parameter change notification for notifying the mobile phone 200 that the setting value of the shooting parameter has been changed is transmitted to the mobile phone. At this time, if the setting information has been changed for a plurality of shooting parameters, the setting information of the various shooting parameters that have been changed is notified to the mobile phone 200 for each shooting parameter.

  Also, for example, when the user gives a shooting instruction to the mobile phone 200 at T311, if the shooting instruction is a still image shooting instruction, the mobile phone 200 sets the still image at T312. Is sent to the digital camera 100. In response to the still image shooting request, the digital camera 100 executes still image shooting processing at T313.

  On the other hand, if the shooting instruction given to the mobile phone 200 by the user at T311 is a video shooting instruction, the mobile phone 200 transmits a video shooting request to the digital camera 100 at T314. In response to the moving image start request, the digital camera 100 executes moving image shooting processing at T315.

  As described above, remote shooting is executed with the digital camera 100 from the mobile phone 200 via the wireless LAN connection.

  Here, as described above, the digital camera 100 notifies the mobile phone 200 of setting information of various shooting parameters when starting remote shooting.

  In the digital camera 100 capable of seamless still image shooting and moving image shooting regardless of the shooting mode, at this timing, the setting information of various shooting parameters is not related to whether it is related to still image shooting or moving image shooting. All information is notified to the mobile phone 200.

  However, if all the various shooting parameters are displayed on the remote control application operating on the mobile phone 200, a large display area is required. In addition, it is difficult for the user to understand whether each shooting parameter is useful for still image shooting or moving image shooting, and an erroneous operation such as erroneously setting an unusable setting may occur.

  Therefore, in this embodiment, a still image shooting view and a moving image shooting view can be selectively displayed on a remote control application that operates on the mobile phone 200, and a GUI suitable for still image shooting and moving image shooting is displayed in each view. I will provide it.

  That is, the mobile phone 200 determines whether or not various shooting parameters are parameters useful for still image shooting, and whether or not the parameters are useful for moving image shooting. Then, according to the determination result, the mobile phone 200 displays shooting parameters and remote still image shooting buttons useful for still image shooting in the still image shooting view. On the other hand, the mobile phone 200 displays shooting parameters and remote moving image shooting buttons that are useful for moving image shooting in the moving image shooting view.

  Hereinafter, remote photographing will be described with reference to the drawings.

<Example of remote shooting screen display>

  FIG. 4A shows an example of a remote shooting screen displaying a still image shooting view suitable for still image shooting. On the other hand, FIG. 4B shows an example of a remote shooting screen displaying a moving image shooting view suitable for moving image shooting.

  In FIG. 4, a view switching button 401 is an operation member for switching between a still image shooting view and a moving image shooting view. The user presses one of the still image icon on the left side of the figure and the moving image icon on the right side of the figure shown in the view switching button 401, and the still image shooting view shown in FIG. ) Can be switched and displayed.

  The live view display area 402 is an area for displaying a live view image transmitted from the digital camera 100 at T306 in FIG. Each time the live view image is transmitted at T306, the mobile phone 200 updates the display of the live view display area 402.

Reference numeral 404j denotes a shooting parameter display including an icon indicating a set value of the recording size of the still image. In FIG. 4A, a still image is recorded as a Jpeg image of S2 size (for example, 1920 × 1440) as the setting value. Is displayed. Reference numeral 404k denotes a shooting parameter display including an icon indicating the setting of the moving image recording image quality. In FIG. 4B, the shooting parameter display 404k indicates that a moving image is recorded with a recording quality of MP4 format, a frame rate of 24 fps, and a full HD (full high-definition) size (1920 × 1080) as a set value. Yes.

  The various shooting parameter displays displayed in the shooting parameter display areas 403 and 404 also serve as a setting unit for each shooting parameter. Specifically, when the setting value of the corresponding shooting parameter can be changed, the setting value of the corresponding shooting parameter can be changed by pressing the shooting parameter display. In FIG. 4, the shooting parameter display that can be pressed in the shooting parameter display areas 403 and 404 is displayed in a state surrounded by a frame line, and which shooting parameter setting value can be changed by the user. Can be visually recognized. Of course, as long as the user can visually recognize, the method of indicating whether or not the photographing parameter display can be pressed is not limited to this.

  When the user presses one of the shooting parameter displays surrounded by the frame lines of the shooting parameter display areas 403 and 404, the mobile phone 200 displays a setting area for changing the corresponding shooting parameter. FIG. 4C shows a shooting parameter setting change UI displayed when a shooting parameter display 404g including an icon indicating a white balance mode is pressed as a shooting parameter. A parameter setting area 410 displays a list of setting values that can be changed with respect to the pressed shooting parameter. Therefore, in the example shown in FIG. 4C, all setting values that can be changed in the white balance mode are displayed as icons in the parameter setting area 410. In the parameter setting area 410, when the number of icons to be displayed is large, the setting value that can be changed can be confirmed by the user scrolling left and right.

  By pressing any icon of the icons displayed in the parameter setting area 410, the user can give a shooting parameter change instruction corresponding to T307. At this time, the mobile phone 200 transmits a photographing parameter setting value change request indicated by T308 in FIG. In response to this, the digital camera 100 changes the setting value of the shooting parameter at T309, and further transmits a shooting parameter change notification notifying that the shooting parameter has been changed to the mobile phone 200.

  Upon receiving the shooting parameter change notification, the mobile phone 200 updates the corresponding shooting parameter display shown in the shooting parameter display areas 403 and 404 as necessary, as will be described later with reference to FIG.

  Thus, the user can change the setting value of the shooting parameter.

  Here, among various shooting parameter displays in the shooting parameter display areas 403 and 404, only those determined to be useful for shooting a still image are displayed in the still image shooting view, and useful for shooting a movie in the moving image shooting view. Only those determined to be are displayed.

  A still image shooting button 405 shown in FIG. 4A is an operation button for instructing still image shooting. When pressed, the mobile phone 200 transmits a still image capturing request indicated by T312 in FIG. 3 to the digital camera 100, and at T313, the digital camera 100 performs still image capturing processing.

  A moving image shooting button 406 shown in FIG. 4B is an operation button for instructing moving image shooting. When pressed, the mobile phone 200 transmits a moving image shooting request indicated by T314 in FIG. 3 to the digital camera 100 at T314, and the digital camera 100 performs moving image shooting processing at T315.

  Here, in the following description, the still image shooting button 405 and the moving image shooting button 406 may be collectively referred to as “shooting buttons”.

  Here, the mobile phone 200 displays the still image shooting button 405 and does not display the moving image shooting button 406 in the still image shooting view shown in FIG. On the other hand, the mobile phone 200 does not display the still image shooting button 405 but displays the moving image shooting button 406 in the moving image shooting view shown in FIG.

  The end button 407 is a button for accepting an instruction to end the remote shooting function. When pressed, the mobile phone 200 notifies the digital camera 100 of a request to end the remote shooting function and disconnects communication.

<Processing flow of mobile phone 200>
5A and 5B are flowcharts showing a procedure of UI display update processing at the time of remote shooting, which is executed in the mobile phone 200. FIG.

  In FIG. 5A, first, when the mobile phone 200 detects that there is a remote shooting instruction from the user (corresponding to T301 in FIG. 3), the mobile phone 200 requests the digital camera 100 to start remote shooting in step S501. Send. This process corresponds to T302 in FIG.

  Next, in step S502, the mobile phone 200 starts displaying a remote shooting screen. This corresponds to T304 in FIG.

  In step S503, the mobile phone 200 sets an initial value as a view setting value and stores the initial value in the work memory 204. In this embodiment, since the initial value of the view setting value is the still image shooting view, the setting value indicating the still image shooting view is stored in the work memory 204. Thereafter, a still image shooting view is displayed as a remote shooting screen based on the view setting values stored in the working memory 204.

  In step S504, the mobile phone 200 determines whether or not a shooting parameter change notification has been received from the digital camera 100. Here, the imaging parameter change notification is notified from the digital camera 100 at T305 and T310 in FIG. When the mobile phone 200 receives the shooting parameter change notification from the digital camera 100 (YES in step S504), the mobile phone 200 proceeds to step S505. On the other hand, when the imaging parameter change notification has not been received from the digital camera 100 (NO in step S504), the process proceeds to step S508.

  In step S505, the mobile phone 200 stores the setting information of various shooting parameters included in the shooting parameter change notification from the digital camera 100 in step S504 in the shooting parameter setting information list. Here, the shooting parameter setting information list is a list used to hold setting information for each shooting parameter of the digital camera 100 in the mobile phone 200, and every time there is a shooting parameter change notification, the working memory 204 is stored. Is stored and updated.

  FIG. 7 shows an example of the shooting parameter setting information list held in the work memory 204 in FIG. In the shooting parameter setting information list, setting information (current setting values and a list of currently changeable values) transmitted from the digital camera 100 is stored for each shooting parameter.

  FIG. 7 shows that the aperture value currently set for the digital camera 100 is F2.0, for example. In addition, the aperture value is set to any one of values F2.0, F2.8, F3.4, F5.6, F6.3,. It is shown that the setting can be changed.

  In addition, regarding the shooting parameters whose changeable list is described as “(None)” in FIG. 7, the mobile phone 200 indicates that the user cannot change the setting value. In FIG. 7, for example, the user cannot change the setting value of the shooting mode on the mobile phone 200.

  Returning to FIG. 5A, in step S506, the mobile phone 200 sets the setting information of various shooting parameters included in the shooting parameter change notification received in step S504 as a display update target in the shooting parameter display update process performed in step S507. To do.

  In step S507, the mobile phone 200 performs a shooting parameter display update process for the setting information of various shooting parameters set in step S506. Details of the imaging parameter display update processing will be described later with reference to FIG. Note that when a shooting parameter change notification is received for a plurality of shooting parameters, the shooting parameter display update process here is the same as the process shown in steps S512 to S516, which will be described later, using the variable i. It is executed repeatedly for the number of parameters. That is, the setting information of various shooting parameters included in the shooting parameter change notification received from the digital camera 100 in step S504 is sequentially set as a display update target in the shooting parameter display update process.

  In step S508, the mobile phone 200 determines whether or not there is a view switching instruction. In the present embodiment, the mobile phone 200 determines that a view switching instruction has been issued when the pressing of the view switching button 401 shown in FIG. 4 is detected. If there is a view switching instruction (YES in step S508), the cellular phone 200 proceeds to step S509. On the other hand, when there is no view switching instruction (NO in step S508), the process proceeds to step S510 in FIG. 5B.

  In step S509, the mobile phone 200 updates and stores the view setting value in the work memory 204 based on the view switching instruction detected in step S508. Specifically, when the still image icon is selected with the view switching button 401, the mobile phone 200 updates the view setting value to the still image shooting view and stores it. On the other hand, when the moving image icon is selected by the view switching button 401, the mobile phone 200 updates the view setting value to the moving image shooting view and stores it.

  Next, in step S510, the mobile phone 200 determines whether or not the view setting value has been changed. If the view setting value has been changed (YES in step S510), the process proceeds to step S511. On the other hand, if the view setting value has not been changed (NO in step S510), the process proceeds to step S517.

  In step S511, the mobile phone 200 reads the view setting value stored in the work memory 204 and updates the display of the shooting button according to the value. Specifically, when the view setting value is a still image shooting view, the mobile phone 200 displays a still image shooting button 405 and hides the moving image shooting button 406. On the other hand, when the view setting value is the moving image shooting view, the mobile phone 200 hides the still image shooting button 405 and displays the moving image shooting button 406.

  In step S512, the mobile phone 200 stores 0 in the variable i. Here, the variable i is a loop counter for repeatedly executing the processes of steps S513 to S516.

  In step S513, the mobile phone 200 determines whether the variable i is less than the number of items in the shooting parameter setting information list. If the variable i is less than the number of items in the shooting parameter setting information list (YES in step S513), the cellular phone 200 proceeds to step S514. On the other hand, if the variable i is greater than or equal to the number of items in the shooting parameter setting information list (NO in step S513), the repetition process of steps S513 to S516 is terminated, and the process proceeds to step S517.

  In step S514, the mobile phone 200 sets the setting information of the i-th shooting parameter in the shooting parameter setting information list as setting information of shooting parameters to be subjected to the shooting parameter display update process performed in step S515.

  In step S515, the mobile phone 200 performs a shooting parameter display update process for the shooting parameter setting information set in step S514.

  In step S516, the mobile phone 200 increments the variable i by 1, and returns to step S513.

  On the other hand, in step S517, the mobile phone 200 determines whether or not there is an instruction to end remote shooting. In this embodiment, when it is detected that the end button 407 has been pressed, it is determined that there has been an instruction to end remote shooting. If there is an instruction to end remote shooting (YES in step S517), the mobile phone 200 ends the process of FIG. On the other hand, when there is no remote shooting end instruction (NO in step S517), the mobile phone 200 returns to step S504 in FIG. 5A.

  Note that the determination of whether or not there has been an instruction to end remote shooting is not limited to the method of this embodiment. For example, when the user has not operated the mobile phone 200 for a certain period of time, it may be determined that there has been an instruction to end remote shooting. Further, when there is a disconnection notification from the digital camera 100, it may be determined that there is an instruction to end remote shooting.

  The above is the UI display update processing at the time of remote shooting in which the mobile phone 200 displays the operation GUI suitable for each of the still image shooting view and the moving image shooting view on the remote shooting screen.

  Next, the imaging parameter display update process performed in the mobile phone 200 in steps S507 and S515 in FIG. 5 will be described with reference to FIG.

  FIG. 6 is a flowchart showing the procedure of the imaging parameter display update process performed by the mobile phone 200.

  First, in step S601, the mobile phone 200 reads the current view setting value from the work memory 204, and determines whether the read view setting value is a still image shooting view or a moving image shooting view. Here, the view setting value is set in one of steps S503 and S509 in FIG. If the view setting value is a still image shooting view (YES in step S601), the process proceeds to step S602. If the view setting value is a moving image shooting view (NO in step S601), the process proceeds to step S603.

  In step S602, the mobile phone 200 determines whether or not the shooting parameter that is the display update processing target is useful for still image shooting according to a method that will be described later with reference to FIG. If the mobile phone 200 determines that the shooting parameters to be processed are useful for still image shooting (YES in step S602), the process proceeds to step S604. On the other hand, when the mobile phone 200 determines that the shooting parameter to be processed is useful for moving image shooting (NO in step S602), the process proceeds to step S605.

  On the other hand, in step S603, the mobile phone 200 determines whether or not the shooting parameter that is the display update process target is useful for moving image shooting according to a method described later with reference to FIG. If the mobile phone 200 determines that the shooting parameters to be processed are useful for moving image shooting (YES in step S603), the process proceeds to step S604. On the other hand, when the mobile phone 200 determines that the shooting parameters to be processed are useful for still image shooting (NO in step S603), the process proceeds to step S605.

  In step S <b> 604, the mobile phone 200 confirms the current setting value with reference to the shooting parameter setting information list regarding the shooting parameter to be processed for display update. Thereafter, based on the confirmed current setting value, the imaging parameter display relating to the imaging parameter in the imaging parameter display areas 403 and 404 is updated and displayed. At this time, the cellular phone 200 sets a frame of a character string indicating the updated current setting value (exposure correction value), for example, as in the shooting parameter display 404d for shooting parameters whose number of settable value lists is two or more. Displayed in a state surrounded by a line to indicate that the setting can be changed. Thereafter, the imaging parameter display update process shown in FIG.

  On the other hand, in step S <b> 605, the mobile phone 200 deletes (that is, hides) the shooting parameter display related to the shooting parameter to be processed for display update from the shooting parameter display area 404. Thereafter, the imaging parameter display update process shown in FIG.

  Next, referring to FIG. 6, a method for determining whether or not the shooting parameters performed in step S602 are useful for still image shooting, and a method for determining whether or not the shooting parameters are useful for moving image shooting performed in step S603. explain.

  In the present embodiment, the mobile phone 200 stores the shooting parameter determination table in a non-volatile manner in order to confirm whether any shooting parameter is useful for still image shooting and whether it is useful for moving image shooting. Stored in the memory 203.

  As shown in FIG. 8, the shooting parameter determination table includes information for identifying whether each shooting parameter is related to a still image or a moving image.

  Specifically, in FIG. 8, four item names of “shooting parameter” 801, “related: still image” 802, “related: moving image” 803, and “fixed value at the time of moving image shooting” 804 are displayed in the heading row. Exists. In each column of “shooting parameters” 801, shooting parameters are arranged. In “relevant: still image” 802, a value indicating whether or not the shooting parameter shown in each column of “shooting parameter” 801 is related to a still image (still image related parameter) is stored. Further, “relation: moving image” 803 stores a value indicating whether or not the shooting parameter shown in each column of “shooting parameter” 801 is related to a moving image (moving image related parameter). Here, in each column of “relevant: still image” 802 and “relevant: moving image” 803, a value of “◯” is stored for the related items, and a value of “x” is stored for the unrelated items.

  Note that some of the shooting parameters of the digital camera 100 are those whose setting values are changed to default fixed values due to restrictions when shooting is started (fixed value parameters). In “Fixed value during moving image shooting” 804 in FIG. 8, fixed values to be changed are stored for shooting parameters that are changed to default fixed values when moving image shooting is started in the digital camera 100. . In this embodiment, a value “AUTO” indicating the AUTO mode is stored. Here, the AUTO mode refers to a setting for calculating an appropriate value with the digital camera 100 and photographing. In the example of FIG. 8, since “AUTO” values are stored for the aperture value, shutter speed, and ISO value among the shooting parameters, user setting values for these shooting parameters are ignored during moving image shooting. . When the digital camera 100 starts moving image shooting, the digital camera 100 transmits a shooting parameter change notification including appropriate values for these shooting parameters to the mobile phone 200. However, between the time when the user selects the moving image icon with the view switching button 401 and the time when the shooting parameter change notification is received, the setting values displayed on the shooting parameter display of these shooting parameters are set as the user setting values. It is not preferable to leave it. This is because the user is unaware that moving image shooting is actually performed at a setting value different from the user setting value displayed in the shooting parameter display of these shooting parameters, which may cause misrecognition and erroneous operation. Because there is sex.

  Therefore, in this embodiment, the mobile phone 200 refers to the shooting parameter determination table for each shooting parameter, and determines that the parameter is useful for still image shooting when it is a still image related parameter. On the other hand, referring to the shooting parameter determination table for each shooting parameter, it is a shooting parameter useful for moving image shooting when it is a moving image related parameter and other than a fixed value parameter that is changed to a fixed value during moving image shooting. Judge.

  The still image shooting view and the moving image shooting view shown in FIGS. 4A and 4B refer to the shooting parameter setting information list (FIG. 7) and the shooting parameter determination table (FIG. 8), and shooting parameter display areas 403 and 404 are displayed. Appropriate shooting parameters are displayed. For example, regarding the moving image recording image quality, the mobile phone 200 determines that it is not useful for still image shooting because it is not a still image related parameter as a result of referring to the shooting parameter determination table of FIG. For this reason, the mobile phone 200 does not display the moving image recording image quality in the still image shooting view shown in FIG.

  For example, regarding the drive mode, the mobile phone 200 determines that the mobile phone 200 is not useful for moving image shooting because it is not a moving image related parameter as a result of referring to the shooting parameter determination table of FIG. For this reason, the mobile phone 200 does not display the drive mode in the moving image shooting view shown in FIG. Further, for example, with respect to the ISO value, the mobile phone 200 is a moving image-related parameter as a result of referring to the shooting parameter determination table of FIG. Judge that it is not. Also in this case, the mobile phone 200 does not display the ISO value in the moving image shooting view shown in FIG.

  As described above, in the system in which the mobile phone 200 performs remote shooting control on the digital camera 100, the still image shooting view and the moving image shooting view are selectively displayed on the mobile phone 200. In addition, regarding the various shooting parameters transmitted from the digital camera 100, the mobile phone 200 displays only parameter setting values that are useful for still image shooting in the still image shooting view, and is useful for moving image shooting in the moving image shooting view. Displays only parameter settings.

  As a result, even when the digital camera 100 is capable of still image shooting and movie shooting regardless of the shooting mode, the mobile phone 200 can display a display suitable for each shooting without unnecessarily securing a large display area. Is possible. In addition, since only the parameters necessary for the user's intended shooting can be displayed and the setting can be changed, it is possible to prevent an erroneous operation by the user.

  In the present embodiment, the initial value of the view setting value is set to the still image shooting view in step S503 in FIG. 5, and view display is performed. However, for example, the view setting value may be changed according to the shooting mode notified from the digital camera 100. That is, when the setting value of the shooting mode notified from the digital camera 100 is the moving image mode, the mobile phone 200 may change the view setting value to the moving image shooting view and update the display. According to this, according to the setting of the digital camera 100, it is possible to automatically switch to a view that seems to be more appropriate and display it.

  Further, for example, the mobile phone 200 stores the view setting value when the remote shooting function is used even after the remote control application ends, and sets it as the initial value when the remote shooting function is used next time. It may be. Further, for example, the mobile phone 200 stores the display frequency of the still image shooting view and the moving image shooting view, and uses the view setting value with the higher display frequency as the initial value at the start of remote shooting. Good.

  In this embodiment, when the setting information of the shooting parameters is changed in the digital camera 100, the shooting parameter change notification is sent from the digital camera 100 to the mobile phone 200, and the mobile phone 200 sets the shooting parameter according to the notification. Updated the information list. However, the timing of updating the shooting parameter setting information list is not limited to the timing shown in the present embodiment. For example, the digital camera 100 may periodically notify the mobile phone 200 of shooting parameter setting information. Further, for example, the mobile phone 200 may request the digital camera 100 to transmit shooting parameter setting information at a necessary timing, and may be able to acquire the digital camera 100 accordingly.

  In addition, regarding the shooting parameter determination table, in particular, shooting parameters that are changed to fixed values during moving image shooting may vary depending on the model of the imaging device that performs remote control. For this reason, the mobile phone 200 holds a shooting parameter determination table for each type of imaging device, acquires device identification data for identifying the imaging device after establishing communication with the imaging device, and based on the acquired device identification data You may make it select the table to be used. In this embodiment, the device identification data is acquired from the digital camera 100 via the communication unit 212. However, the present invention is not limited to this. For example, device identification data may be acquired from the digital camera 100 via the communication unit 211 before starting remote shooting.

  In this embodiment, the determination of the usefulness of still image shooting in step S602 of FIG. 6 and the determination of the usefulness of moving image shooting in step S603 are based on the shooting parameter determination table held in the nonvolatile memory 203. Yes, but not limited to this. For example, the shooting parameter determination table may be transmitted from the digital camera 100 to the mobile phone 200.

  When determining the usefulness of moving image shooting in step S603, shooting parameters that are changed to fixed values during moving image shooting are also not displayed in the moving image shooting view in the same manner as shooting parameters not related to moving image shooting. It was. However, the criteria and display method are not limited to this. For example, in step S603, the mobile phone 200 may display the shooting parameter display of the shooting parameter that is changed to a fixed value during moving image shooting in the moving image shooting view. Further, in this case, a character string (for example, “FIXED”) indicating that it is a fixed value corresponding to the shooting parameter display of the shooting parameter that is changed to a fixed value during moving image shooting or a specific fixed value is displayed. May be. Furthermore, regarding the shooting parameter display of the shooting parameter that is changed to a fixed value during moving image shooting, the setting may not be changed regardless of the contents of the changeable value list. FIG. 9A shows a display example of the moving image shooting view in such a case. In the shooting parameter determination list shown in FIG. 9A, regarding the aperture value, shutter speed, and ISO value, a value “AUTO” indicating that the mode is changed to the AUTO mode during moving image shooting is stored. For this reason, when the mobile phone 200 is switched to the moving image shooting view, “AUTO” is displayed as the setting values of the shooting parameter displays 404b, 404c, and 404e of the aperture value, shutter speed, and ISO value. Further, as shown in FIG. 9A, the aperture value, shutter speed, and ISO value shooting parameter displays 404b, 404c, and 404e are not surrounded by a frame line regardless of the contents of the changeable value list. The setting values of these shooting parameters by the user cannot be changed. This makes it easier for the user to grasp that these shooting parameters are automatically changed during moving image shooting, and avoids unnecessary setting changes.

  In addition, when the user instructs to switch to the moving image shooting view with the view switching button 401, there is a shooting parameter that is changed to a fixed value during moving image shooting when the current setting value is different from the fixed value. A warning display may be performed. FIG. 9B shows an example of warning display. In FIG. 9B, reference numeral 901 denotes a warning display indicating that the current setting value of the shooting parameter is not reflected.

  Further, at the same time that the warning is displayed, a shooting parameter setting change request may be transmitted to the digital camera 100 so that the setting value of the shooting parameter is changed to a fixed value. By doing in this way, the live view image which a user can visually recognize with the mobile telephone 200 can be made close to the image at the time of actually image | photographing.

  Further, in this embodiment, the description has been made assuming that there is a shooting parameter that changes to a fixed value only during moving image shooting, but the same determination and processing are performed for a shooting parameter that changes to a fixed value only during still image shooting. You may make it perform.

  As mentioned above, although the preferable Example of this invention was described, this invention is not limited to these Examples, A various deformation | transformation and change are possible within the range of the summary.
