  Next, Example 1 of the present invention will be described. In this embodiment, a remote operation system (communication system) for adjusting the posture of the image sensor 103 as intended by the user by remote operation from the remote operation device 200 and avoiding posture adjustment unintended by the user. The configuration and operation will be described. The remote operation system of the present embodiment is configured by, for example, the imaging device 100 shown in FIG. 1 and the remote operation device 200 shown in FIG.

  With reference to FIG. 5, the operation | movement at the time of remote imaging | photography by the remote operation system (the imaging device 100 and the remote operation device 200) in a present Example is demonstrated. FIG. 5 is a flowchart showing the operation of the remote operation system during remote operation. Each step in FIG. 5 is mainly executed based on a command from the CPU 111 of the imaging device 100 or the CPU 211 of the remote operation device 200.

  First, when the imaging apparatus 100 is turned on in step S591, the CPU 111 displays an image (live view image) acquired by the imaging unit 110 on the display unit 116. In step S592, the CPU 111 determines whether or not the remote operation photographing mode (remote operation mode) is selected by the mode switching unit 120. When the remote operation shooting mode is selected in step S592, the imaging apparatus 100 enters a standby state for a communication connection request from the remote operation apparatus 200. On the other hand, if the remote operation shooting mode is not selected, that is, if the normal shooting mode is selected, step S592 is repeated.

  When power is turned on to the remote operation device 200 in step S501, in step S502, the remote operation device 200 requests the imaging device 100 to establish a communication connection in order to perform remote operation shooting. In step S593, the imaging device 100 responds to the communication connection request from the remote operation device 200. The imaging apparatus 100 transmits the live view image acquired by the imaging apparatus 100 to the remote operation apparatus 200 after completing the communication connection with the remote operation apparatus 200. In this state, the imaging apparatus 100 can receive an instruction from the remote operation apparatus 200, for example, a zoom instruction, a posture adjustment instruction, a photographing instruction, or a photographing preparation instruction, and can perform an operation corresponding to the received instruction. .

  In step S <b> 503, the remote operation device 200 receives the live view image from the imaging device 100 via the second communication unit 201 and displays it on the display unit 216. Subsequently, in step S504, the posture detection unit 205 detects the posture of the remote control device 200 and notifies the posture adjustment amount determination unit 206 of the detected posture (posture detection result). In step S505, the posture adjustment amount determination unit 206 determines a posture adjustment amount according to the posture (posture detection result) detected by the posture detection unit 205. Then, the posture adjustment amount determining unit 206 instructs the image capturing apparatus 100 to perform posture adjustment via the second communication unit 201.

  In this embodiment, the posture detection unit 205 is an acceleration sensor, for example. The posture adjustment amount determination unit 206 is configured to adjust the posture adjustment amount Rad (x) of the imaging unit 110 according to the output value Vrad (x) = Vrad (1), Vrad (2),. ) = Rad (1), Rad (2),..., Rad (n) are determined. For example, when the output value Vrad (x) of the posture detection unit 205 is Vrad (1) (Vrad (x) = Vrad (1)), the posture adjustment amount determination unit 206 sets the posture adjustment amount Rad (x) to Rad. (1) is determined (Rad (x) = Rad (1)). Similarly, when the output value Vrad (x) = Vrad (2) of the posture detection unit 205, the posture adjustment amount determination unit 206 determines posture adjustment amount Rad (x) = Rad (2). Thus, when the output value Vrad (x) = Vrad (n) of the posture detection unit 205, the posture adjustment amount determination unit 206 determines the posture adjustment amount Rad (x) = Rad (n).

  Subsequently, in step S594, the CPU 111 (imaging element moving unit 124) adjusts the attitude of the imaging unit 110 according to the attitude adjustment amount (instruction adjustment instruction received from the remote operation device 200) determined in step S505. In step S594, a control signal (for example, a posture adjustment amount) based on the posture of the remote control device 200 is input via the first communication unit 122, and the posture of the image sensor 103 is determined based on the control signal. Including the step of adjusting. After the posture adjustment is completed in step S594, in step S506, the remote control device 200 receives the live view image acquired by the imaging device 100 via the second communication unit 201, and displays it on the display unit 216. indicate.

  Subsequently, in step S507, the CPU 211 determines whether or not the shooting preparation instruction receiving unit 203 has received a shooting preparation instruction, that is, whether or not a shooting preparation instruction has been issued by the remote operation device 200. When a shooting preparation instruction is performed in step S507, the remote operation device 200 transmits a shooting preparation instruction to the imaging device 100. In step S595, the imaging apparatus 100 prepares for shooting. On the other hand, if a shooting preparation instruction has not been issued in step S507, the process proceeds to step S503. At this time, the user can adjust the posture of the imaging unit 110 to the posture intended by the user by changing the posture of the remote control device 200 while checking the live view image displayed on the display unit 216. It becomes.

  When the imaging apparatus 100 completes the preparation for shooting in step S595, the process proceeds to step S596. In step S596, the imaging unit 110 holds the posture adjusted in step S594, and transmits the live view image after shooting preparation to the remote control device 200. The posture adjustment amount determination unit 206 holds the posture before the shooting preparation instruction while the shooting preparation instruction is performed, and does not perform the posture adjustment instruction according to the posture detection signal after the shooting preparation instruction. For example, when the output value of the posture detection unit 205 before the shooting preparation instruction is given is Vrad (x) = Vrad (1), the posture adjustment amount determination unit 206 sets the posture adjustment amount to Rad (x) = Rad ( 1) is determined. When a shooting preparation instruction is subsequently issued, the posture adjustment amount determination unit 206 holds the posture adjustment amount Rad (x) = Rad (1) before the shooting preparation instruction is issued. As described above, the posture adjustment amount determination unit 206 holds the posture adjustment amount Rad (x) = Rad (1) while the shooting preparation instruction is performed. For example, even when the output value of the posture detection unit 205 changes to Vrad (x) = Vrad (2) while the shooting preparation instruction is performed, the posture adjustment amount determination unit 206 does not change the posture adjustment amount Rad (x ) = Rad (1) is not changed.

  In step S508, the remote control device 200 notifies the user that the posture is maintained. This notification is performed, for example, by displaying a user interface (UI display) on the display unit 216 as shown in FIG. FIG. 7 is a diagram illustrating a user interface (UI) of the remote operation device 200. As shown in FIG. 7, the display unit 216 locks the posture while the shooting preparation instruction is being performed, and “message is locked”, “message: the posture is locked while the shooting preparation instruction is being performed. If you want to change your posture, please cancel the shooting preparation instruction ”.

  The notification start timing is after the shooting preparation instruction and after the imaging apparatus 100 holds the posture before the shooting preparation instruction. The notification end timing is after the shooting preparation instruction is canceled. The notification content is that the posture of the imaging unit 110 is held in the posture before the shooting preparation instruction while the shooting preparation instruction is performed. The notification content is that the posture adjustment of the imaging unit 110 cannot be performed even if the posture of the remote control device 200 is changed while the shooting preparation instruction is being performed. The notification content is to cancel the shooting preparation instruction when the posture of the imaging unit 110 is adjusted. As the notification contents, any one of the notification contents described above may be notified, or a plurality of notification contents may be notified. When notifying a plurality of notification contents, the notification contents may be changed over time, for example, every second, between the notification start timing and the notification end timing. When a plurality of notification contents are notified, a plurality of notification contents may be notified at the same time.

  In this embodiment, the notification start timing, the notification end timing, and the notification content are set in this way. As a result, the remote operation device 200 informs the user that the posture adjustment of the imaging unit 110 cannot be performed even if the posture of the remote operation device 200 is changed while the user is instructing the shooting preparation. be able to. For this reason, it is not a failure of the remote operation device 200 or the imaging device 100 that the user cannot adjust the posture of the imaging unit 110 even if the posture of the remote operation device 200 is changed while giving a shooting preparation instruction. Can be determined. In step S508, even when the posture detection signal from the remote control device 200 (posture detection unit 205) changes, the CPU 211 issues a posture adjustment instruction to the image pickup device 100 while the shooting preparation instruction is being performed. Not performed.

  Subsequently, in step S509, the CPU 211 determines whether or not a shooting instruction has been received by the shooting instruction receiving unit 204, that is, whether or not a shooting instruction has been performed. If no shooting instruction is given in step S509, the process returns to step S507. On the other hand, when a shooting instruction is issued in step S <b> 509, the CPU 211 transmits a shooting instruction to the imaging apparatus 100. In step S597, the imaging apparatus 100 (CPU 111) performs shooting, and a series of operations in this flow ends (step S598). In this embodiment, when the time required from the shooting preparation instruction to the shooting instruction is within a predetermined period (within a predetermined period in the imaging apparatus 100), for example, within 100 ms (when pressed at once), the instruction is issued. The posture adjustment instruction according to the posture detection signal generated at this time is not performed.

  According to the present embodiment, the posture of the imaging unit can be easily adjusted from the remote operation device during remote operation shooting, and the posture change (for example, camera shake) that occurs while holding the shooting preparation instruction is performed. By not transmitting to the imaging device, the influence can be reduced.

  Next, a second embodiment of the present invention will be described. The remote operation system according to the present embodiment can assign the posture detection signal to the imaging instruction function during the imaging preparation instruction.

  With reference to FIG. 8, the structure of the remote control apparatus in a present Example is demonstrated. FIG. 8 is a block diagram showing the configuration of the remote control device 200a. The remote operation device 200a according to the present embodiment is different from the remote operation device 200 according to the first embodiment in that a function switching unit 807 is provided. Other configurations of the remote operation device 200a are the same as those of the remote operation device 200 of the first embodiment. In addition, the imaging apparatus 100 according to the first embodiment can be applied to the present embodiment.

  The function switching unit 807 switches the connection destination (output destination) of the detection signal (output signal) of the posture detection unit 205. The detection signal of the posture detection unit 205 is output to either the posture adjustment amount determination unit 206 or the shooting instruction reception unit 204 via the function switching unit 807 and the internal bus 231. Unless otherwise specified, the detection signal of the posture detection unit 205 is output to the posture adjustment amount determination unit 206. The function switching unit 807 performs switching control so that the connection destination is switched according to whether there is a shooting preparation instruction. When there is a shooting preparation instruction, the function switching unit 807 is connected to the shooting instruction receiving unit 204. On the other hand, when there is no shooting preparation instruction, the function switching unit 807 is connected to the posture adjustment amount determining unit 206.

  Next, with reference to FIG. 6, an operation at the time of remote shooting by the remote operation system (the imaging device 100 and the remote operation device 200a) in the present embodiment will be described. FIG. 6 is a flowchart showing the operation of the remote operation system during remote operation. Each step of FIG. 6 is mainly executed based on a command from the CPU 111 of the imaging device 100 or the CPU 211 of the remote operation device 200a. Note that steps S601 to S608 and steps S691 to S698 in FIG. 6 are the same as steps S501 to S508 and steps S591 to S598 in FIG.

  In step S611 in FIG. 6, the function switching unit 807 switches the connection destination (output destination of the posture detection signal output from the posture detection unit 205) from the posture adjustment amount determination unit 206 to the imaging instruction reception unit 204. Subsequently, in step S612, the CPU 211 (or the shooting instruction receiving unit 204) compares the posture detection signals Vradt1 and Vradt2 that are temporally continuous, and determines whether or not the posture change of the remote operation device 200a has occurred. When the posture change occurs in step S612, the photographing instruction receiving unit 204 transmits the posture change to the imaging apparatus 100 as a photographing instruction. In step S697, the imaging apparatus 100 performs shooting, and the series of operations in this flow ends (step S698).

  On the other hand, when the posture change of the remote control device 200a has not occurred in step S612, the process proceeds to step S613. In step S613, the CPU 211 determines whether or not the shooting preparation instruction performed in step S607 is held. If the shooting preparation instruction is held, the process returns to step S612, and the imaging apparatus 100 enters a shooting instruction standby state. On the other hand, if the shooting preparation instruction is not held in step S613, the process proceeds to step S614. In step S614, the function switching unit 807 switches the output destination of the posture detection signal output from the posture detection unit 205 from the photographing instruction reception unit 204 to the posture adjustment amount determination unit 206, and returns to step S604.

  According to the present embodiment, while the shooting preparation instruction is held, the posture detection signal can be assigned to a shooting instruction that is an instruction other than posture adjustment. Note that the function switching means of the present embodiment can be configured to switch to a function other than the shooting instruction, for example, an exposure time changing function for changing the exposure time or an exposure correction amount changing function for changing the exposure correction amount. .
