  In the digital camera 100, the process of step S302 is performed until a connection request from the smartphone 200 is received in step S303, and the unique information of the smartphone 200 that has requested the connection in step S304 is confirmed. If the connection is approved in step S305, the connection is established in step S307 in response to the connection request in step S306.

  The smartphone 200 receives the response from the digital camera 100 in step S306, detects a successful connection in step S356, and enters the communication state in step S357.

  In this way, in step S354 on the smartphone 200 and in step S305 on the digital camera 100, the procedure for displaying the specific information of the other party to be connected and approving the user is called pairing. Once pairing is established, the digital camera 100 and the smartphone 200 store connection setting information for identifying the individual, such as the access point setting and the ID and MAC address of the connection partner smartphone 200, and register them as external device connection settings. . For reconnection, authentication is automatically performed without confirmation from the user.

  <Description of Remote Camera Application> Next, with reference to FIG. 4, a remote camera application executed on the smartphone 200 of this embodiment will be described.

  FIG. 4 is a camera control screen 400 displayed on the display unit 207 after the remote camera application is activated and communication between the digital camera 100 and the smartphone 200 is established.

  The camera control screen 400 is a GUI displayed on the display unit 207 after the remote camera application is activated and communication between the digital camera 100 and the smartphone 200 is established by the procedure described with reference to FIG. The camera control screen 400 is provided with an image display area 401 for displaying live view images and playback images received from the digital camera 100. Various operation units are displayed as icons 402 to 409 around the image display area 401 on the camera control screen 400, and the user can instruct execution of various functions by touching desired icons.

  A shooting start button 402 is tapped to process an image currently displayed in the image display area 401 according to the shooting mode, for example, start or stop of moving image recording, or still image shooting instruction. It can be performed. Furthermore, in the still image mode, when a long press is performed, processing for performing continuous shooting or the like is executed. At the start of shooting, the system control unit 221 outputs a shutter sound via the audio output unit 225.

  By tapping the parameter change button 403, the setting of the shooting mode and shooting parameters can be changed. The shooting mode is, for example, a program mode, shutter speed priority, aperture priority, manual mode, and the like, and the shooting parameters are, for example, a shutter speed value, an aperture value, an ISO sensitivity value, an exposure correction value, and the like. The shooting parameters of the current camera are displayed so that the set value can be visually recognized by the user, for example, superimposed on the live view image. The parameter change button 403 can switch the shooting mode of the digital camera 100 to a shooting mode such as moving image, still image, square, panorama. In the image confirmation button 404, after the shooting start button 402 is tapped, thumbnails of images shot or recorded by the digital camera 100 are sequentially updated and displayed. Further, by tapping the image confirmation button 404, the screen is switched to a reproduction mode screen that is displayed in the image display area 401 so that the user can browse images captured or recorded in the past with the digital camera 100. In addition, by tapping the image confirmation button 404, an image reproduced in the image display area 401 can be taken into the smartphone 200.

  By tapping this on the live view on / off button 405, the digital camera 100 can be set to the live view mode, and the display of the live view image can be stopped or started (restarted). In the live view mode, the digital turtle 100 transmits a live view image to the smartphone 200, and the smartphone 200 sequentially displays the live view image received from the digital camera 100. By turning off the live view mode, the power consumption of the digital camera 100 can be saved and the temperature rise can be suppressed. The vertical / horizontal lock button 406 can lock the function of automatically switching the layout of the camera control screen 400 to vertical / horizontal according to the tilt information of the smartphone 200 detected by the tilt detection unit 230. The parameter display on / off button 407 can be tapped to stop or start the display of the shooting parameter displayed superimposed on the image display area 401. The end button 408 can be tapped to end the remote control mode and transition to another mode. The refocus button 409 can be focused on the subject surrounded by the focus frame 410 superimposed on the live view image by tapping this button. Further, the focus position can be moved by dragging the focus frame 410. With such a user interface, it is possible to perform photographing by remote operation while confirming the live view image received from the digital camera 100.

  <Inclination Correction> Next, with reference to FIG. 5, an inclination correction process executed by the smartphone 200 of this embodiment on an image photographed by the digital camera 100 will be described.

  As shown in FIG. 5A, when the user determines that tilt correction is necessary by looking at the live view image in the image display area 401, the tilt correction function can be turned on by tapping the parameter change button 403. . When the tilt correction function is turned on, the system control unit 221 executes tilt correction processing on the live view image according to the tilt information of the smartphone 200 detected by the tilt detection unit 230. Specifically, the trimming frame 501 is displayed so as to overlap the live view image displayed in the image display area 401. The trimming frame 501 is always displayed in the horizontal direction regardless of the tilt of the smartphone 200 (that is, the live view image being displayed), and when the smartphone 200 is tilted, the position of the trimming frame 501 with respect to the live view image is updated in real time.

  In addition, the system control unit 221 displays a new trimming frame lock button 502 adjacent to the parameter display on / off button 407 around the image display area 401. The trimming frame lock button 502 can lock the current trimming frame 501 by tapping this button. The user may tap the trimming frame lock button 502 when the position of the trimming frame 501 becomes a desired positional relationship with respect to the live view image while tilting the smartphone 200. In this case, for example, in the example of FIG. 5, the orientation of the subject in the live view image is horizontal / vertical with respect to the trimming frame 501, and the user tilts the smartphone 200 so that the subject is not tilted. Lock it.

  When the lock state is set, the tilt information of the smartphone 200 detected by the tilt detection unit 230 at that time is stored, and the system control unit 221 corrects the tilt of the live view image based on the tilt information. Determine the amount. In this state, the user waits for a photo opportunity and taps the shooting start button 402 to execute shooting processing. At this time, the smartphone 200 stores the tilt correction amount to be applied to the tilt correction of the captured image in the system memory 223.

  When the captured image is generated, a thumbnail is displayed on the image confirmation button 404. When the image confirmation button 404 is tapped, a captured image is taken from the digital camera 100 into the smartphone 200. The smartphone 200 executes tilt correction processing based on the tilt correction amount stored at the time of image shooting on the captured image captured from the digital camera 100, previews the image, and stores the image data after tilt correction.

  This inclination correction processing is performed by the inclination correction processing unit 221a mounted on the system control unit 221 of the smartphone 200. The tilt correction processing unit 221a performs digital rotation processing on the captured image based on the tilt correction amount. The digital rotation process is a process of cutting an image along the trimming frame 501 by the trimming process.

  In this way, it is possible to apply tilt correction to image data stored in the smartphone 200 without changing the attitude of the digital camera 100. Accordingly, the user can use the image data stored in the smartphone 200 as it is in the cloud or the like, so that the workflow can be shortened.

<Image display after tilt correction processing>
FIG. 5B shows a state in which an image after tilt correction is displayed on the camera control screen 400 of the smartphone 200.

  As shown in FIG. 5B, by displaying the horizontal / vertical grid-like grid lines 551 on the image after tilt correction, the user can easily confirm the orientation of the subject after tilt correction. . Note that grid lines 551 may be used instead of the trimming frame 501 when the smartphone 200 is tilted to adjust the tilt of the image.

  [Second Embodiment] Next, a second embodiment will be described.

  In the present embodiment, the tilt detection unit 601 is mounted on the digital camera 100, and the tilt information of the digital camera 100 when the digital camera 100 detects the image detected by the tilt detection unit 601 together with the live view image (described later in FIG. 7). Camera tilt information 712) is transmitted. Further, the camera control screen 400 of the smartphone 200 is adjusted so that the digital camera 100 is not inclined with respect to the live view image. After making the adjustment in this way, the smartphone 200 performs a tilt correction process of the captured image.

  FIG. 6A is a block diagram illustrating a configuration of the digital camera 100 of the present embodiment. In the following, the same components as those in FIG. 1 are denoted by the same reference numerals, description thereof will be omitted, and different points will be mainly described.

  The digital camera 100 according to the present embodiment includes an inclination detection unit 601. The tilt detection unit 601 detects the tilt angle θ of the digital camera 100 with respect to the gravity direction or the horizontal direction as tilt information.

  As shown in FIG. 6B, the digital camera 100 according to the present embodiment is superimposed on the live view image displayed on the display unit 107 based on the camera tilt information detected by the tilt detection unit 601. Instrument information 611 and horizontal position display 612 are displayed. Accordingly, the user can easily adjust the inclination of the live view image while viewing the level information 611 and the horizontal position display 612.

  <Tilt Correction Processing> Next, with reference to FIG. 7, the camera control screen 400 of the smartphone 200 when the smartphone 200 of the present embodiment performs tilt correction of the captured image using the tilt information of the digital camera 100 will be described. .

  FIG. 7 shows a camera control screen 400 displayed on the smartphone 200 of the present embodiment. The same components as those in FIG. 1 are denoted by the same reference numerals, description thereof is omitted, and different points are mainly described.

  As shown in FIG. 7A, when the user taps the parameter change button 403 and the tilt correction function is turned on, a level display 710 is displayed in the image display area 401. The system control unit 221 displays a horizontal display 711 on the live view image in accordance with the tilt information of the smartphone 200 detected by the tilt detection unit 230. The horizontal display 711 indicates a horizontal direction orthogonal to the direction of gravity with respect to the posture of the smartphone 200. In addition, the system control unit 221 displays the camera tilt information 712 in a superimposed manner on the live view image in which the horizontal display 711 is superimposed. The camera tilt information 712 corresponds to the tilt information of the digital camera 100 acquired together with the live view image from the digital camera 100. As shown in FIG. 7B, the tilt correction process of the present embodiment is performed so that the difference between the horizontal display 711 as the first index and the camera tilt information as the second index disappears. The smartphone 200 may be tilted and locked so that the camera tilt information display 712 overlaps the same line. When the horizontal display 711 and the camera tilt information display 712 are overlapped on the same line, the line color may change or a sound may be emitted.

  The processing after the locked state is as described in FIGS. 4 and 5A of the first embodiment. In the present embodiment, the tilt correction function can be set to the auto mode. When the tilt correction function is set to the auto mode, the camera automatically shifts to the lock state based on the camera tilt information 712 acquired from the digital camera 100 together with the live view image, and the tilt correction amount is determined. Thereby, the user can save the captured image whose inclination is always corrected in the smartphone 200 without being aware of the inclination correction.

  [Third Embodiment] Next, a third embodiment will be described.

  In the first and second embodiments, the smartphone 200 performs the tilt correction process on the image captured by the digital camera 800. In this case, the tilt correction is applied to the original image stored in the digital camera 800. End up with no image. Therefore, in this embodiment, the digital camera 800 performs tilt correction processing on the captured image.

  FIG. 8 is a block diagram showing the configuration of the digital camera 800 of this embodiment. In the following, the same components as those in FIG. 1 are denoted by the same reference numerals, description thereof will be omitted, and different points will be mainly described. The configuration of the smartphone 200 is the same as that in FIG. 2 of the first embodiment. However, in the present embodiment, since the image data after tilt correction can be acquired from the digital camera 800, the smartphone 200 does not necessarily have the tilt correction function. It may not have.

  The digital camera 800 of this embodiment includes an image sensor driving unit 801 that rotationally drives the image capturing unit 104 in the roll direction, a drive control unit 802 that controls the image sensor driving unit 801, and an acceleration sensor 803 that detects acceleration applied to the image capturing apparatus 800. , An inclination / blur detection unit 804 is provided.

  The acceleration sensor 803 is, for example, a triaxial acceleration sensor, and detects gravitational acceleration applied to the camera, an acceleration component of shake applied to the camera, and the like. The tilt / shake detection unit 804 detects gravitational acceleration among the accelerations applied to the camera by the acceleration sensor 803, and determines camera tilt information. In the present embodiment, the tilt attitude information of the camera includes at least a rotation angle in the direction around the optical axis (roll direction) of the imaging optical system with respect to the direction of gravity. In addition, the tilt information (pitch direction) may be included in the tilt information of the camera for use in, for example, a level.

  Further, when the acceleration sensor 803 detects an acceleration (for example, an acceleration component of shake applied to the camera) different from the gravitational acceleration, the tilt / shake detection unit 804 detects the external acceleration applied to the camera.

The system control unit 121 includes a shake correction control unit 805 and an inclination correction control unit 806. The tilt correction control unit 805 calculates a control amount (tilt correction amount) for rotating the imaging unit 104 by the imaging sensor drive control unit 802 based on the camera tilt information detected by the tilt / shake detection unit 804. . The imaging sensor drive control unit 802 detects an inclination angle with respect to a horizontal direction orthogonal to the gravitational direction, and calculates a control amount for correcting the inclination angle.
Further, the tilt correction control unit 806 compares the tilt information of the camera detected by the tilt / shake detection unit 804 with the tilt state of the imaging unit 104 detected by the imaging sensor drive control unit 802, and there is a difference. Drives the image sensor driving unit 801 with the control amount calculated by the image sensor driving control unit 802, rotates the image capturing unit 104 in the roll direction (in a plane orthogonal to the optical axis), and performs tilt correction.

  Next, tilt correction processing by the digital camera 800 of the present embodiment will be described with reference to FIG.

  FIG. 9A shows a state in which the posture of the digital camera 800 is inclined by θ ° in the roll direction. When photographing is performed in this state, an inclined image as shown in FIG. 9B is photographed. Here, by rotating the imaging unit 104 by θ ° in the roll direction by the imaging sensor driving unit 801, the captured image and the live view are displayed even when the digital camera 800 is tilted as shown in FIG. 9C. An image without inclination can be generated by performing inclination correction on the image. Note that additional information such as information indicating that the inclination has been corrected and information on the amount of inclination correction (rotation angle θ °) may be recorded in the captured image on which the inclination correction has been performed.

<Digital rotation processing>
When the tilt of the captured image is corrected by rotating the imaging unit 104, the range in which the imaging sensor drive control unit 802 can rotate the imaging unit 104 is limited and exceeds the movable range of the imaging unit 104. The tilt correction cannot be performed. Therefore, as another tilt correction method, the image processing unit 111 can execute digital rotation processing on the captured image to correct the tilt. However, when tilt correction is performed by digital rotation processing, the resolution of the captured image may be reduced. In addition, since the captured image needs to be trimmed, the viewing angle of the image may be reduced. FIG. 9D illustrates a captured image to which digital rotation processing is applied. The tilted image shown in FIG. 9B can be tilt-corrected by rotating the tilted image by the tilt angle θ by digital rotation processing, but the region 901 in FIG. 9D is cut out from the captured image data by trimming processing. There is a need. Since the size of the door image data to be trimmed is reduced, it is necessary to execute digital enlargement processing when it is desired to make the image sizes equal. However, these digital image processing may cause image degradation, Will reduce the viewing angle.

  Note that in the case of a camera not equipped with the acceleration sensor 803, image analysis is performed on the tilted captured image as shown in FIG. 9B to determine the tilt angle θ from the captured image, and tilt correction is applied. It is also possible.

  According to the present embodiment, by performing tilt correction on a captured image in the digital camera 800 and transmitting the tilt-corrected captured image to the smartphone 200, the original image stored in the digital camera 800 is also displayed on the smartphone 200. Tilt correction can also be applied to images stored in.

  Note that the digital camera 800 of this embodiment can receive the tilt correction amount and tilt information from the smartphone 200, and the digital camera 800 can perform tilt correction processing. With this configuration, an image that is intentionally tilted can be taken by remote control without moving the digital camera 800. That is, even if the digital camera 800 fixed on the tripod is tilted, tilt correction can be freely performed when the smartphone 200 remotely captures images, and at the same time, tilt correction can be applied to captured images stored in the camera. can do.

Alternatively, the system control unit 121 performs tilt correction processing on the image data acquired in step S1052 using the tilt information received from the smartphone 200 in step S1007 and the tilt information of the digital camera 800 detected by the tilt detection unit 601. Run. In this case, priority is given to the tilt correction request received from the smartphone 200 side.

  In step S1055, the system control unit 121 holds the live view image data in the memory 109 and displays the live view image on the display unit 107. If the tilt correction is performed in step S1054, the system control unit 121 performs the tilt correction. An image is displayed.

  In step S1056, the system control unit 121 determines whether or not the live view image acquisition request in step S1003 has been received. If received, the process proceeds to step S1057. If not received, the process proceeds to step S1058. .

  In step S1057, the system control unit 121 transmits image data equivalent to the live view image stored in the memory 109 and displayed on the display unit 107 to the smartphone 200 in step S1055.

  In step S1058, the system control unit 121 determines whether or not the shooting command in step S1010 has been received. If it has been received, the process proceeds to step S1059. If not, the process proceeds to step S1063. Instead of receiving the shooting command, the shooting process may be executed based on the second shutter switch signal SW2 of the second shutter switch 120.

  In step S <b> 1059, the system control unit 121 executes a shooting process of recording the image data displayed in live view on the recording medium 128 when the shooting command is received.

  In step S1060, similarly to step S1053, the system control unit 121 determines whether or not the tilt correction function is on. If it is on, the system control unit 121 proceeds to step S1061, and if it is off, the system control unit 121 proceeds to step S1062. The tilt correction function can be set on the digital camera side and can be set from the smartphone 200 side in steps S1007 and S1008.

  In step S1061, similarly to step S1054, the system control unit 121 uses the tilt information of the digital camera 800 detected by the tilt detection unit 601 to rotate the imaging unit 104 or acquire the image processing unit 111 in step S1052. A tilt correction process is executed on the image data. Alternatively, the system control unit 121 executes tilt correction processing on the image data acquired in step S1052 using the tilt information received from the smartphone 200 in step S1007 and the tilt information of the digital camera 800 detected by the tilt detection unit 601. .

  As described above, according to the digital camera 800 of the present embodiment, the digital camera 800 is intentionally tilted without moving by receiving the tilt correction amount and tilt information from the smartphone 200 and performing tilt correction. Images can be taken remotely. In this way, even when the digital camera 800 fixed on the tripod is tilted, tilt correction can be freely performed when the smartphone 200 remotely captures an image, and at the same time, the tilt correction is also performed on a captured image stored in the camera. Can be applied.

  [Fourth Embodiment] Next, a fourth embodiment will be described.

  The digital camera 800 of this embodiment can be set to an auto mode that automatically applies tilt correction to a live view image or a captured image during remote control by the smartphone 200. Depending on the intention of producing the photographed image, there is a case where the photograph is intentionally tilted, so that the tilt correction function can be set valid / invalid by the user. The setting state of the auto mode is stored in the nonvolatile memory 124.

  When the tilt correction function is set to the auto mode, the digital camera 800 automatically transmits a live view image and a captured image that have been tilt corrected to the smartphone 200. In addition, the smartphone 200 automatically determines a lock state with respect to the live view image transmitted from the digital camera 800, and transmits an inclination correction amount for performing the inclination correction by the digital camera 800. Accordingly, the user can A captured image whose inclination is always corrected without being aware of correction can be stored in the digital cameras 100 and 800 and the smartphone 200.

  However, the acceleration sensor 803, the tilt / shake detection unit 804, and the image sensor drive control unit 802 of the digital camera 800 are used not only for tilt correction but also for camera shake correction. The shake correction control unit 805 calculates a direction and an amount of movement to cancel the acceleration component of shake applied to the camera detected by the tilt / shake detection unit 804, and the image sensor 104 by the image sensor drive control unit 802 and the image sensor drive unit 801. Rotation control is performed. If both the image stabilization and tilt correction functions are enabled, the correction effects will be slightly inferior, so in view of normal use cases, the image stabilization will be enabled in the factory default settings. The tilt correction function is disabled.

  Therefore, in the present embodiment, during remote control by the smartphone 200, the setting of the tilt correction function of the digital camera 800 is automatically changed to valid and the tilt correction function is set after the remote control is finished (after disconnection). The configuration is configured to automatically revert to the original invalid setting.

  <Description of Remote Camera Application> Next, with reference to FIG. 11, a remote camera application executed on the smartphone 200 of this embodiment will be described.

  FIG. 11 shows a camera control screen 400 displayed on the display unit 207 after the remote camera application is activated and the digital camera 800 and the smartphone 200 are connected.

  In the camera control screen 400 of FIG. 11, a setting change button 1101 is different from the screen of FIG. The setting change button 1101 can be manually switched by the user on the camera control screen 400 of the smartphone 200 to enable / disable the tilt correction function of the digital camera 800 so that the tilt correction function is not automatically enabled. Other screen configurations are the same as those in FIG.

  <Inclination Correction Function Setting Change Process> Next, a process for automatically changing the inclination correction function setting in the digital camera 800 of this embodiment will be described with reference to FIG.

  In the digital camera 800 of this embodiment, when the connection with the smartphone 200 is established by the procedure of FIG. 3, the setting of the tilt correction function is automatically switched to be effective.

  The process in FIG. 12 is started when the remote camera application of the smartphone 200 is activated and the digital camera 800 can be remotely controlled by the smartphone 200.

  In step S1201, when the connection between the digital camera 800 and the smartphone 200 is established by the procedure of FIG. 3, the process proceeds to step S1202.

  In step S <b> 1202, the system control unit 121 stores the current valid / invalid setting value of the tilt correction function in the nonvolatile memory 124 and saves the set value in the system memory 123. In remote control using the smartphone 200, there are many use cases in which the digital camera 800 is fixed to a tripod, and there are many cases in which camera shake correction is not necessary. Therefore, the camera shake correction may be set to be disabled at the same time as the tilt correction function is enabled. . In that case, in step S602, the setting value related to camera shake correction is also stored in the nonvolatile memory 124, and the setting value in the system memory 123 is saved.

  In step S1203, the system control unit 121 sets the tilt correction function to be valid. Here, the camera shake correction function is disabled as necessary. Since this setting change is temporary, it is not always necessary to change the setting value of the nonvolatile memory 124.

  In step S <b> 1204, the system control unit 121 performs shooting by remote control using the smartphone 200. In this case, since the tilt correction function is enabled, the live view image in the image display area 401 of the camera control screen 400 displayed on the display unit 207 of the smartphone 200 is also displayed with tilt correction applied. Further, when the shooting process is performed, not only the shot image stored in the digital camera 800 but also the shot image transmitted to the smartphone 200 is the one to which the tilt correction is applied. Note that the captured image is not an image that is intentionally set by the user to enable the tilt correction function, so that it is recorded in the captured image as additional information that tilt correction is applied to the captured image. Good. When the user wants to capture an image that is intentionally tilted, a setting change request for the tilt correction function is transmitted to the digital camera 800 by tapping the setting change button 1101 shown in FIG. The function can be arbitrarily enabled / disabled.

  Thereafter, in step S1205, the remote control in step S1204 is continued until the connection is disconnected upon receiving a disconnection request from the smartphone 200. When the connection is disconnected, the process proceeds to step S1206. Note that the shooting instruction in the remote control is not limited to the tap of the shooting start button 402 of the smartphone 200. Photographing may also be performed by operating the physical shutter button 114 of the digital camera 800, and an image whose inclination has been corrected may be transmitted to the smartphone 200.

  In step S1206, the system control unit 121 returns the setting value saved from the system memory 123 in step S1202 to the original value, and ends the process.

  According to the above-described embodiment, it is possible to prevent a failure in which an image is inclined in photographing a commemorative photo using a tripod without the photographer being conscious. Further, since there is no need to return the setting value to the original value after the remote control shooting is completed, it is possible to save the operation and to perform shooting that is the same as in the past.
