Next, FIG. 2 is a diagram conceptually showing an embodiment of an imaging apparatus according to the present invention.
In FIG. 2, the camera body 100 and the smartphone 105 are in communication,
The smartphone 105 is in communication shooting mode. The photographer (user) is in a state of remotely operating the camera body 100 using the smartphone 105 at a location away from the camera body 100.




The camera body 100 includes an image display unit 919 on the back surface (surface opposite to the subject side), and displays an imaging range from the imaging device. However, the photographer must
Since the image display unit 919 of the camera body 100 cannot locate the imaging range. However, in the system according to the present embodiment, an image captured by the imaging unit (imaging device) 912 of the camera body 100 is transmitted to the smartphone 105 via the wireless communication unit 913 on the camera body 100 side and the wireless communication unit 901 on the smartphone 105 side. Has been sent to. Therefore, the imaging range displayed on the image display unit 919 of the camera body 100 is displayed on the image display unit 906 of the smartphone 105 at the hand of the photographer, and the photographer can check the captured image.

FIG. 2 is a diagram showing that the interchangeable lens 120 (photographing lens) is inscribed in the image circle 110, and FIGS. 2C and 2D are diagrams showing the image display unit 906 of the smartphone 105. In the present embodiment, the positional relationship between the effective imaging region 111 of the imaging unit (imaging device) 912 and the image circle 110 is a positional relationship as shown in FIG.
As shown in FIGS. 2A and 2D, when the camera body 100 is placed in a horizontal posture (horizontal position) and the smartphone 105 is placed in a horizontal posture, an image of the camera body 100 is displayed on the image display unit 906 of the smartphone 105. The same image as the display unit 919 is displayed. The image 101 displayed on the image display unit 919 of the camera body 100 is reflected in the capture area 112 in the effective imaging area 111 of the imaging unit (imaging element) 912 when the camera body 100 is in the horizontal attitude (lateral position). It is an image. That is, the imaging range of the image 107 displayed on the image display unit 906 of the smartphone 105 is the imaging unit (imaging element) 912 when the camera body 100 is in the horizontal posture (lateral position).
This is the same as the region 112 indicated by the double-weighted line in the effective imaging region 111. If there is no problem in the imaging range, the photographer issues an instruction to execute the release operation from the smartphone 105, and the camera body 100 receives the information of the release operation and executes the shooting.

Next, as shown in FIG. 2A and FIG. 2C, when the smartphone body 105 is in the vertical posture while the camera body 100 is in the horizontal posture (horizontal position), the change in the posture information of the smartphone 105 is wirelessly communicated. It is transmitted to the camera body 100 via the unit 901. Then, a region 113 indicated by a dotted line in the effective imaging region 111 of the imaging unit (imaging device) 912 of the camera body 100.

The “done” mark 907 in FIG. 3F will be described in S350 of FIG. 4 described later. The “done” mark 907 is not limited to the indication “done”, but “◎” or “☆”
Any shape or text may be used. In this way, by displaying the “done” mark on the display screen of the smartphone 105, the photographer can easily confirm that the imaging range of the camera body 100 has been switched, and can perform shooting smoothly. it can.
The photographer confirms the image 302 displayed on the image display unit 906 of the smartphone 105, and
The amount of rotation correction necessary for correcting the orientation of the imaging range of the imaging unit (imaging device) 912 of the camera body 100 is examined. Then, as shown in FIG. 3D, the photographer changes the posture (rotation angle) of the smartphone 105 by the necessary rotation correction amount. The camera body 100 receives the information on the posture change of the smartphone 105 (including information related to the rotation angle), and FIG.
As indicated by a dotted line in a), the imaging range of the imaging element 912 (attitude of the imaging range) is trimmed from the imaging range 101 to the trimming region 300 by different rotation amounts according to the angles.
In this way, the photographer changes the posture of the smartphone 105 that is communicating with each other without changing the posture of the camera body 100, so that the image pickup unit (image pickup device) 91 of the camera body 100 is changed.
The posture of the two imaging ranges can be switched, and an image desired by the photographer can be taken.

Next, the above operation will be described with reference to the flowchart shown in FIG. FIG. 4 shows the camera body 10.

The functions of the smartphone 105 according to the present embodiment include an operation function of the smartphone 105 alone and an operation function performed by communicating with the camera body 100. In the flow shown in FIG. 4, operation functions performed by communicating with the camera body 100 will be described.
First, the photographer turns on the power of the smartphone 105 and the camera body 100 and starts a connection operation between the camera body 100 and the smartphone 105.
In S300, the CPU 902 of the smartphone 105 confirms whether the communication setting mode of the smartphone 105 is the communication shooting mode or the communication reproduction mode. This mode switching is performed by the photographer operating a mode switching member included in the operation unit 903. If the result confirmed by the CPU 902 in S300 is the communication shooting mode, S305
If it is the communication reproduction mode, the process proceeds to S400.

First, the communication procedure and shooting procedure between the smartphone 105 and the camera body 100 in the communication shooting mode of the smartphone 105 after S305 will be described. S40
The communication playback mode of the smartphone 105 after 0 will be described after the description of the communication shooting mode.
In step S <b> 305, the CPU 902 receives a through image from the camera body 100 by wireless communication, and sets the wireless communication unit 901 and the image display unit 906 to display the through image on the image display unit 906.
In step S <b> 310, the CPU 902 transmits information indicating that the setting of the smartphone 105 is set to the communication shooting mode to the camera body 100 via the wireless communication unit 901.
In S <b> 100, the CPU 911 receives information indicating that the setting of the smartphone 105 is in the communication shooting mode via the wireless communication unit 913.
In S105, the CPU 911 confirms the content of the information received in S100, and the smartphone 1
It is confirmed whether the communication setting mode 05 is the communication shooting mode or the communication reproduction mode. If the confirmed result is the communication shooting mode, the process proceeds to S110, and if it is the communication reproduction mode, the process proceeds to S2.
Proceed to 00.

First, the smartphone 1 in the communication shooting mode of the camera body 100 after S110.
A communication procedure between 05 and the camera body 100 and a photographing procedure will be described. S200
The subsequent communication playback mode of the camera body 100 will be described after the description of the communication shooting mode.
In S110, the CPU 911 sets the communication shooting mode. The communication shooting mode of the camera body 100 is a mode in which shooting is performed by communication with the smartphone 105 instead of shooting by operation of the operation unit 915 of the camera body 100.
In S <b> 115, the CPU 911 transmits the through image captured by the imaging unit 912 and displayed on the image display unit 919 to the smartphone 105 via the wireless communication unit 913. In the present embodiment, the image size of the through image to be transmitted is the same size as the image size displayed on the image display unit 919. However, the present invention is not limited to this, and when the number of display elements of the image display unit 913 of the camera body 100 and the image display unit 906 of the smartphone 105 is greatly different, the size of the image to be transmitted is set to the number of display elements of the image display unit 906 of the smartphone 105. It may be resized to a suitable size and transmitted.
In step S <b> 315, the CPU 902 displays the through image received via the wireless communication unit 901 on the image display unit 906.
In S <b> 120, the CPU 911 confirms the posture information in the initial state of the camera body 100 acquired by the imaging range detection unit 924.
In S <b> 125, the CPU 911 transmits the initial posture information to the smartphone 105 via the wireless communication unit 913.
In S320, the CPU 902 receives the posture information of the initial state of the camera body 100 transmitted from the camera body 100 in S125 via the wireless communication unit 901.

For example, when the camera body is shooting in a horizontal posture as shown in FIG. 2A, in S125, the CPU 911 causes the horizontal posture image 101 in FIG. Posture information indicating the presence is transmitted to the smartphone 105. When the photographer is looking at the smartphone 105 in the horizontal posture as shown in FIG. 2D, the CPU 902 displays the landscape image 107 based on the image received from the camera body 100 and the posture information of the imaging range in S320. indicate. Further, when the CPU 902 receives posture information indicating that the posture information of the imaging range is a vertical posture, the CPU 902 displays a vertically long image that is resized by cutting the left and right of the received image. On the other hand, when the photographer is looking at the smartphone 105 in a vertical posture, when the CPU 902 receives a landscape image, the top and bottom of the received image is cut and resized to display a resized landscape image.
The photographer confirms the composition of the captured image based on the through image received in S315 and the initial posture information of the camera body 100 received in S320. In the present embodiment, the composition of the captured image can be changed in the rotation direction on the plane perpendicular to the optical axis of the imaging element of the imaging unit 912 of the camera body 100. An operation method performed by the photographer on the smartphone 105 in order to realize the change is that the photographer performs the operation on the smartphone 105 on the horizontal plane with the image display unit 906.
This is an operation to rotate. (Fig. 3 (d) above)
The photographer who has confirmed the composition of the captured image tilts the smartphone 105 by a necessary tilt amount if the composition is to be changed. If the composition is not changed, the smartphone 105 is not tilted.

In S325, the CPU 902 detects whether the smartphone 105 is tilted by the photographer. If the posture of the smartphone 105 is tilted, the process proceeds to S330, and if not, the process proceeds to S355.
In step S <b> 330, the posture sensor 907 detects the tilt amount A of the posture of the smartphone 105.
In S335, the CPU 902 transmits the tilt amount A detected in S330 to the camera body 100 via the wireless communication unit 901.
In S <b> 130, the CPU 911 receives the tilt amount A of the smartphone 105 transmitted in S <b> 335 via the wireless communication unit 913.
In S135, the CPU 911 switches the imaging range of the imaging unit 912 based on the tilt amount A of the smartphone 105 received in S130. Switching the imaging range of the imaging unit 912 specifically determines the trimming range as described with reference to FIGS.
In S <b> 140, the CPU 911 transmits to the smartphone 105 information indicating that the through image in the imaging range switched in S <b> 135 and the image have been corrected via the wireless communication unit 913.
In S145, the CPU 911 transmits information indicating that the through image transmitted in S140 has been corrected to the smartphone 105 via the unprecedented communication unit 913.
In step S340, the CPU 902 transmits the camera body 100 in step S140 via the wireless communication unit 901.
The through image transmitted from is received and displayed on the image display unit 906.
In step S345, the CPU 902 sends the camera body 100 in step S145 via the wireless depth unit 901.
Receives information sent from.
In S350, the CPU 902 displays on the image display unit 906 that the through image received in S340 has been corrected. This is because the “done” mark 90 in the image display section of FIG.
7 points.

The photographer confirms the through image displayed on the image display unit 906 of the smartphone 105 through S340 and S350. The through image is the smartphone 105 by the photographer.
This is after the composition is changed by the rotation operation of the posture. The photographer can determine whether it is necessary to further change the composition by looking at the through image. If it is not necessary to change the composition, the release operation can be performed with the operation unit 903 of the smartphone 105.
In step S355, the CPU 902 detects whether a release operation has been performed by the photographer using the operation unit 903. If the CPU 902 detects that a release operation has been performed, the CPU 902 performs S360.
If the release operation is not detected, the process returns to S325, and from S325 to S355.
Repeat the above loop. When repeating the second and subsequent loops, the CPU 902 determines whether or not S32
If it is detected in 5 that the posture of the smartphone 105 is tilted, the “completed” mark 907 displayed on the image display unit 906 indicating that the correction has been completed is ended. When the CPU 902 receives again information that the through image has been corrected from the camera body 100 in step S345 via the wireless communication unit 901, the CPU 902 displays the corrected “completed” mark 907 on the image display unit 906 again.
In step S <b> 360, the CPU 902 transmits a signal indicating that the release operation of the operation unit 903 has been performed by the photographer via the wireless communication unit 901.
In S150, the CPU 911 receives a signal indicating that the release operation of the operation unit 903 of the smartphone 105 transmitted in S360 is performed via the wireless communication unit 913.
In step S155, the CPU 911 executes shooting and acquires the captured image as a recording (storing) image.

After shooting, the CPU 911 transmits the shot recording image to the smartphone 105 via the wireless communication unit 913 in S160. Note that the image data transmitted at this time may be image data of an image size captured by the camera body 100, or may be image data resized according to the display size of the image display unit 906 of the smartphone 105. The size of the image data to be transmitted can be manually set in advance by the photographer. When the photographer does not manually set, the camera body 100 automatically sets. In the case of automatic setting of the camera body 100, image data is transmitted in accordance with the display size, the remaining memory capacity, and the remaining battery capacity of the image display unit 906 as the transmission destination. In this case, the display size and the remaining memory capacity of the image display unit 906 of the smartphone 105 as information on the communication shooting mode from the smartphone 105 in S310,
Information on the remaining battery level is transmitted, and the camera body 100 side uses the transmitted information to determine the size of the image data to be transmitted.
In step S365, the CPU 902 receives the recording captured image transmitted in step S160 via the wireless communication unit 901.
In S370, the CPU 902 displays the captured image for recording received in S365 on the image display unit 906.
Here, in the state where the photographed image is displayed on the image display unit 906 after the photographing and the photographer confirms the recording captured image, even if the posture of the smartphone 105 is changed, the information on the posture change is Not transmitted to the camera body 100.
The photographer confirms the recording image captured by the image display unit 906 of the smartphone 105.
The photographer determines whether to continue shooting in the communication shooting mode of the smartphone 105 or to switch to the communication playback mode described above. When switching modes, the mode switching member of the operation unit 903 described above is operated.

In step S375, the CPU 902 detects whether the photographer has performed a switching operation of the communication setting mode. If the communication setting mode has not been switched, the process proceeds to S380. If it is detected that the communication setting mode has been switched, the process returns to S300 to repeat the loop from S300 to S375.
The photographer determines whether to turn off the power of the smartphone 105 or not. When turning off the power, the power button of the operation unit 903 is operated.
In step S <b> 380, the CPU 902 detects whether the photographer has operated the power button of the operation unit 903 to turn off the smartphone 105. If the CPU 902 detects that the power button of the operation unit 903 has been operated, the process proceeds to S385. If no power-off operation is detected, the process returns to S320, and the loop from S320 to S380 is repeated.
In S385, the CPU 902 performs an end operation of the communication setting mode. The end operation of the communication setting mode is to transmit information indicating that the power-off operation of the smartphone 105 has been operated by the photographer to the camera body 100. Alternatively, the end operation of the communication setting mode is to receive information indicating that the camera body has been turned off by the photographer in S165 described later. The CPU 902 turns off the power after information transmission / reception performed in this step, and ends this flow.
In S165, the CPU 911 detects whether or not the camera body 100 is turned off by the photographer. If the power is not turned off, the CPU 911 returns to S100 and repeats the loop from S100 to S165. If the power is turned off, the process proceeds to S170.
In step S <b> 170, the CPU 911 supplies power to the camera body 100 via the wireless communication unit 913.

In addition, although the method which transmits a recorded image one by one was demonstrated in this Embodiment as a form which transmits a recorded image from the camera body 100 to the smart phone 105 by S205, for example, a recorded image is the newest. Several images may be transmitted together, or images for each folder recorded in the image recording unit 920 of the camera body 100 may be transmitted. Further, the photographer may arbitrarily select the number and method of transmitting images as described above.

Note that although the present embodiment has been described with respect to still image shooting, the present invention is not limited to still images and can also be applied to moving image shooting. Specifically, when a moving image is being shot in the communication shooting mode, when the through image is displayed on the image display unit 906 of the smartphone 105 (that is, the state before the start of recording), the operations from S325 to S335 described above ( That is, the operation of controlling the posture of the imaging unit 912 from the smartphone 105 is performed, and the change in the posture of the smartphone 105 is reflected in the through image. However, when the photographer operates the recording button of the operation unit 903 of the smartphone 105 to start recording, control is performed so that the change in the attitude of the smartphone 105 is not transmitted to the camera body 100. On the other hand, when playing a video in the communication playback mode, the operation is the same as the still image communication playback mode shown in FIG.
The target of transmission / reception is a video.

The power-off operation of the camera body 100 and the power-off operation of the smartphone 105 are linked in this embodiment, but may be controlled so as not to be linked. For example, when the power is turned off on the camera body 100 side, the power is not turned off on the smartphone 105 side, the communication setting mode may be terminated, and the normal operation mode described above may be switched.

In the above embodiment, as described in FIG. 4, the posture of the smartphone 105 is tilted, and the imaging range of the camera body 100 is corrected by an angle corresponding to the tilt amount. Unlike the above embodiment, the following control may be performed. As illustrated in FIG. 3A, the photographer tilts the posture of the smartphone 105 as illustrated in FIG. 3D in a state where the imaging range of the imaging element of the camera body 100 is the horizontal posture region. At that time, it is assumed that the photographer greatly tilted the smartphone 105 from the horizontal posture. The CPU 911 of the camera body 100 receives the change in the posture information of the smartphone 105, and the magnitude of the posture change is a predetermined amount (
For example, if it is determined that the inclination amount is 45 degrees or more), the imaging range of the imaging element of the camera body 100 is corrected from the horizontal posture region to the vertical posture region at once. Conversely, if the image capturing range of the image sensor of the camera body 100 is in the vertical posture area before correction, if the posture of the smartphone 105 is largely changed from the vertical posture to the horizontal posture, the image sensor of the camera body 100 The imaging range is corrected at once from the vertical posture region to the horizontal posture region. That is, the photographer sets the posture of the imaging range to 9
When the user wants to change the angle by 0 degrees, it is not necessary to perform the operation of tilting the attitude of the smartphone properly by 90 degrees. In addition, although the method of correcting the inclination has been described with respect to the method of switching and controlling between the two postures of the horizontal posture and the vertical posture, the method is not limited to this method, and a method of switching and controlling with three or more postures such as an oblique posture is also possible. Is possible. On the other hand, when the magnitude of the posture change is smaller than the above-described predetermined amount, the image of the camera body 100 is captured according to the amount corresponding to the inclination amount A of the posture information of the smartphone 105 as in the embodiment described in FIG. Change the range posture.
