  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  The camera control apparatus according to the first embodiment of the present invention will be described below.

  FIG. 1 shows a connection example of an imaging system for remotely operating the pan / tilt head imaging apparatus 2 using an operating device 1 (1A, 1B) which is a camera control apparatus according to an embodiment of the present invention. The operation device 1A is connected to the pan / tilt head photographing device 2 via the communication port 11A. The operating devices 1A and 1B are connected via respective communication ports 12A and 11B. The pan / tilt head photographing device 2 includes a camera 21 and a lens 22 and includes a pan / tilt driving unit. When the operator operates the operation unit of the operation device 1A, a control command corresponding to the operation is transmitted to the pan / tilt head photographing apparatus 2. On the other hand, state information representing the current state of the pan / tilt head photographing device 2 is transmitted from the pan / tilt head photographing device 2 to the operating device 1A. When the operating device 1A displays this state information on the display unit, the operator can perform various operations while recognizing the current state of the pan / tilt head photographing device 2. Furthermore, the operating device 1A transmits the acquired state information of the pan / tilt head imaging device 2 and the operating information of the operating device 1A to the operating device 1B. On the other hand, the operation device 1B transmits a control command corresponding to the content of operation of the operation unit of the operation device 1B to the operation device 1A. At this time, the operating device 1A transmits the control command received from the operating device 1B to the pan / tilt head photographing device 2. In this way, the pan / tilt photographing device 2, the operating device 1 </ b> A, and the manipulating device 1 </ b> B communicate bidirectionally so that one pan / tilt photographing device 2 can be controlled by the two operating devices 1.

  The operation unit (operation means) of the operation device 1 may take any form, and is configured by, for example, a zoom lever 13, a focus encoder 14, a joystick 15, a touch panel 16, and a hard switch 17 as shown in FIG. May be. The zoom operation of the lens 22 can be performed by operating the zoom lever 13 back and forth. Further, the focus control of the lens 22 can be performed by rotating the focus encoder 14. Further, the pan / tilt control of the pan / tilt head photographing device 2 can be performed by operating the joystick 15 forward / backward / left / right.

  FIG. 2 shows an example of the screen configuration displayed on the touch panel 16. The touch panel 16 has a function as a display unit for displaying a state and an input function as an operation unit by displaying buttons on the screen. A plurality of buttons and text representing their functions are displayed on the screen of the touch panel 16. For example, the auto white balance function of the camera 21 can be operated by pressing the AWB button 161. Further, by pressing the DEF button 162, the defroster function of the housing glass on the front surface of the camera 21 can be switched on and off. The current state of the defroster function can be displayed by switching the display color or text display of the DEF button 162 in each of ON and OFF. For the other buttons as well, the operation of the assigned function and the display of the state can be similarly performed. In addition, operations that are frequently performed and functions that are desired to prevent erroneous operations can be assigned to the hard switch 17 to further improve operability.

  FIG. 3 is a block diagram showing the internal configuration of the operation device 1. The operating device 1 includes a communication unit 101, a CPU 102, a display processing unit 103, a storage unit 104, an operation recognition unit 105, and another device connection state recognition unit 106 in addition to the communication port and the operation unit described above. When the operator operates the operation unit such as the zoom lever 13, the operation recognition unit 105 recognizes the corresponding operation and outputs the operation content to the CPU 102. When the operation content is input from the operation recognition unit 105, the CPU 102 that is a control unit outputs a control command corresponding to the operation to the communication unit 101. The communication unit 101 serving as a communication unit transmits a control command input from the CPU 102 to a device connected via the communication port 11 or the communication port 12. In addition, the CPU 102 performs display processing of contents according to the operation state of the operation unit input from the operation recognition unit 105 and the state information of the external device received via the communication port 11 or the communication port 12 and the communication unit 101. Output to the unit 103. The display processing unit 103 controls display on the touch panel 16 in accordance with an input from the CPU 102. The other device connection state recognition unit 106 which is a state recognition unit includes a storage unit 104 for storing various setting information and the other operation device 1 connected to the communication port 11 or the communication port 12. Recognizes the connection status of some other controller.

  Next, the processing flow of the CPU 102 when changing the display of the operation device 1 will be described based on the flowchart of FIG.

  First, the CPU 102 checks whether or not the self-operating device is connected to the pan / tilt head photographing apparatus 2 (S101). In general, the operator connects the operating device 1 and the pan / tilt head photographing device 2 only when using the pan / tilt head photographing device 2, and is otherwise unconnected. For this reason, the operation device 1 has a button for switching the connection state with the pan / tilt head photographing device 2 during connection and disconnection. FIG. 5 shows an example of a screen display on the touch panel 16 in a disconnected state. Only the connection button 163 is configured on the touch panel 16. By pressing the connection button 163 from this state, the exchange of communication commands is started, the operation device 1 is in a connected state, and a screen as shown in FIG. 2 is displayed on the touch panel 16 so that various operations can be performed. For this reason, since the operation cannot be performed in the first place when the operation device 1 is in the disconnected state, the subsequent processing is not performed. On the other hand, if it is being connected, information indicating whether the operating device 1 other than its own operating device is being connected is acquired from the other device connection state recognition unit 106 (S102). Based on the information from the other device connection state recognition unit 106, it is determined whether or not there is another operating device 1 connected to the pan / tilt head imaging device 2 (S103). If there is only an operating device, it is operated as a single control mode (S104). On the other hand, when two or more operating devices 1 are connected, that is, when an operating device 1 other than the self-operating device is connected to the pan / tilt head photographing device 2, it is operated in the plural-unit control mode (S105). .

  Hereinafter, the single control mode will be described. FIG. 6 is an example of a connection diagram in the case of the single control mode. While the operating device 1A is being connected to the pan / tilt head photographing device 2, the operating device 1B is in a disconnected state, and communication with the operating device 1A or the pan / tilt head photographing device 2 is not performed. In this case, the operating device 1 that can communicate with the pan / tilt head imaging device 2 is only the operating device 1A, and the pan / tilt head photographing device 2 is operated only from the operating device 1A. In this case, the display unit of the operation device 1A has all functions such as a pan head operation represented by the pan / tilt operation described above, a camera operation represented by auto white balance, and other operations such as a defroster. Can be operated. The display on the touch panel 16 is the same screen as that in the case of normal operation as shown in FIG.

  Next, the operation in the multiple unit control mode will be described. FIG. 7 is an example of a connection diagram in the case of the multiple unit control mode. In this case, not only the operation device 1A but also the operation device 1B is being connected, and the pan / tilt head photographing device 2 can be operated from both the operation devices 1A and 1B. At this time, the function is limited according to the role of each operation device 1. The role of the operation includes an example such as a video engineer or a producer, and the contents of each are stored in the storage unit 104 as setting information. The storage unit 104 stores whether or not each function of the pan / tilt head photographing device 2 can be operated and the priority order when operations between the controllers interfere with each other according to the role of the operation assigned to the controller. Is done.

  As an example, FIG. 8 shows usable functions of each operation device 1 when the operation device 1A is set to be operated by a video engineer and the operation device 1B is set to be operated by a producer. The camera operation for adjusting the brightness and color of the image as typified by auto white balance is an item used by the video engineer, so that it can be operated only when the video engineer is set. In addition, pan head / tilt operation such as pan / tilt operation can be controlled by both video engineer setting and producer setting, but it is a control item mainly used by the producer, so it was set as a producer setting. The operation from the controller is given priority over the operation from the controller set as a video engineer. Furthermore, other functions such as a defroster can be operated by both. In this way, by limiting the functions that can be operated according to the roles of the respective operation devices 1, it is possible to prevent erroneous operations when simultaneously controlling one pan / tilt head photographing device 2 from a plurality of operation devices 1. .

  As described above, the functions that can be operated by the controller 1A are different between the connection state of FIG. Since the operation device 1A in FIG. 6 is in the single control mode, all functions can be operated. On the other hand, since the operation device 1A in FIG. 7 is in the multiple-device control mode set by the video engineer, the pan / tilt head operation may be restricted depending on the operation from another controller set as the producer. The function of the operator who operates the operating device 1A changes depending on the connection state of the other operating device 1B, which is not related to the own operating device 1A. For this reason, even in a situation where the function that can be operated by itself changes dynamically, the touch panel of the operating device 1A can be easily recognized by simply confirming the connected state of the other operating device 1 by visual inspection. The 16 display screens are changed to the normal screens and displayed.

  FIG. 9 and FIG. 10 show examples of the screen of the touch panel 16 of the operating device 1A when shifting to the multiple-unit control mode. In the example of FIG. 9, it is possible to identify the transition to the multiple-device control mode by changing the normal screen and the background color. In the example of FIG. 10, the transition to the multiple-unit control mode can be identified by providing a frame outside the normal screen.

  When the operation device 1B is disconnected, the operation is switched to the single control mode. As a result, all functions can be operated without restriction, and the screen display returns to the normal screen shown in FIG.

  Although the case of the operation device 1A has been described above, the same processing can be performed also in the case of the operation device 1B.

  As described above, when one pan head is operated from a plurality of operation devices, the display is changed so that the connection state of the other operation devices can be easily recognized by the own operation device. As a result, even when the connection status of other operating devices affects the operable functions of the own operating device, it is possible to easily recognize the presence or absence of the effects and operate without impairing operability. Is possible.

  As a system derived from this embodiment, a single pan / tilt head photographing device 2 is operated by two operating devices 1, but the operating device 1 is not limited to two, and a plurality of operating devices are operated. As long as the apparatus 1 can control the same pan / tilt head photographing apparatus 2 at the same time, any form may be used. The connection form can be variously modified, and the number of communication ports of the operation device 1 and the ports to be used are not limited. Regarding the internal structure of the operation device 1, the CPU 102 and other functions are divided into blocks. For example, the CPU 102 includes the communication unit 101, the display processing unit 103, the storage unit 104, the operation recognition unit 105, and the other device connection state recognition unit 106. You may combine a function. The video engineer setting and the producer setting are given as an example of the setting in the multi-unit control mode. However, other settings may be used, and it may be possible to set the validity / invalidity of each individual operation. . Although the background color is changed or a frame is added to the outside of the screen of the touch panel 16 when the screen is changed from the normal screen, the color change may be partly, and the frame may be added at another position on the screen. Absent.

  The second embodiment of the present invention will be described below.

  FIG. 11 is a block diagram showing the internal configuration of the operating device 1 which is a camera control device according to the second embodiment of the present invention. The configuration in FIG. 11 is different from the configuration in the first embodiment shown in FIG. 3 in that an other device operation state recognition unit 107 is added. The other device operation state recognition unit 107 as an operation recognition unit recognizes the operation state of the other operation device by acquiring the control command and state information of the other operation device via the communication port 11 or the communication port 12 and the CPU. .

  Next, the processing flow of the CPU 102 will be described with reference to the flowchart of FIG.

  The processing from S101 to S103 is the same as the processing of the first embodiment shown in FIG. When the own operation device is being connected, the connection state of the other operation device is recognized, and if the other operation device is also connected, the subsequent processing is performed. Next, information on the operation state of the other operation device is acquired from the other device operation state recognition unit 107 (S204), and it is determined whether the stored operation state of the other operation device affects the own operation device. A determination is made (S205). When it is determined that there is no influence while referring to the information regarding the presence / absence of the influence on each operation registered in the storage unit 104 in advance, the subsequent processing is not performed. On the other hand, if it is in a state that affects the self-operating device, the display of the self-operating device is changed (S206).

  FIG. 13 shows an example of the display screen of the touch panel 16 of the own controller when the other controller operates the auto white balance. A warning screen 164 is displayed on the touch panel 16. In general, it is necessary to execute auto white balance when the whole image is white, and the auto white balance is executed after the camera platform 2 is directed to a place where such an image can be acquired. For this reason, when auto white balance is executed from a certain operating device 1, if another operating device 1 that is not aware of it operates pan and tilt, the image changes and the auto white balance is appropriately adjusted. It will not be executed. In order to prevent this, when the other operating device executes auto white balance, the state is displayed on the screen of the own operating device to prompt the operator to warn. Although only the warning screen 164 may be displayed, it is more preferable that an operation that affects the warning screen 164 is prohibited at the same time as the warning screen 164 is displayed (S207).

  For example, when the other operating device performs the auto white balance adjustment as in this example, the self-operating device displays on the touch panel that the auto white balance adjustment is being performed. At the same time, while auto white balance adjustment is being performed by another controller, operations that affect the captured image, such as pan / tilt, aperture, zoom, focus, gain, shutter speed, etc., are prohibited (impossible) And). Thereafter, the CPU 102 continues to acquire the state from the other device operation state recognition unit 107, and determines whether or not the operation of the corresponding other operation device has ended (S208). When the operation is completed, the prohibition of the operation that was prohibited by the self-operating device performed in S207 is canceled (S209), and the display screen is returned to the normal screen (S210).

  As described above, when it is better to prohibit the operation of the own controller according to the operation content of the other controller, the operation status of the other controller affects the own controller, such as displaying a prohibition screen. In such a case, the display of the self-operating device is changed so that the operator can easily recognize it. As such a case, in addition to the illustrated auto white balance adjustment, there is a case where manual operation and auto operation for a specific function are performed simultaneously from different control devices, and control is performed so that manual operation is prioritized. Thereby, it is possible to prevent a malfunction that occurs when the control is performed by a plurality of units at the same time and that is not correctly controlled by the operation of the other controller 1.

  The system derived from this embodiment is the same as that described in the first embodiment. In addition, although the warning screen 164 is displayed on the entire screen, it may be a part of the screen. The display in the warning screen 164 is also an example, and the content may be anything.

  The camera control apparatus according to the third embodiment of the present invention will be described below. The internal configuration of the operating device 1 that is a camera control device is the same as that of the second embodiment shown in FIG.

  The flow of processing of the CPU 102 when processing that can be operated from either operating device 1 is performed as in the other functions described in FIG. 8 will be described with reference to the flowchart of FIG. First, the processing from S101 to S103 and S204 is the same as the processing of the second embodiment described in FIG. When both the own operation device and the other operation device are connected, the CPU 102 acquires the operation state of the other operation device from the other device operation state recognition unit 107. It is determined whether or not the content operated by the other operating device is a function that can be operated with the same priority even in the own operating device (S305). The corresponding operation of the own controller is temporarily prohibited (S306).

  FIG. 15 shows an example of the display screen of the touch panel 16 of the own controller when another controller switches the defroster function ON / OFF. As described in the first embodiment, the defroster function is switched between ON and OFF by pressing the DEF button 162, and can be operated not only by the own controller but also by another controller. When an operation is performed from OFF to ON with another operation device, the state is reflected on the own operation device, and the state of the DEF button 162 of the operation device is also turned ON. For this reason, immediately after the other operation device is operated, when the operation device is to be turned on, the DEF button 162 is operated without noticing the operation of the other operation device, so that the operation device is again turned from ON to OFF. There is a possibility that an erroneous operation of operating will occur. As a method for preventing this, when it is recognized that the operation is performed by another operation device, the operation of the DEF button 162 of the own operation device is temporarily prohibited. The operation may be prohibited only, but preferably, the operation is temporarily prohibited (disabled) by changing the button color of the DEF button 162 corresponding to the operation portion as shown in the figure. This should be clearly indicated (S307). Thereafter, when it is determined that a predetermined time has passed (S308), the prohibition of operation of the own controller performed in S306 is canceled (S309), and the display screen is returned to the normal screen (S310).

  In other words, in the case of operation means that toggles the state in a toggle manner every time the same button on the touch panel is pressed, it is determined that an operation for switching ON / OFF of a predetermined function of the pan / tilt head photographing device 2 by another controller has been performed. In the case of a failure, the operation of the predetermined function from the operation device is limited for a predetermined time. By this control, it is possible to prevent the occurrence of an unstable state in which the state is switched a plurality of times in a short time due to an operation performed with the same intention from different operating devices within a short time.

  As described above, for functions that can be operated with the same priority from both the local controller and other controllers, the corresponding operation is temporarily performed on the local controller when the other controller is operated. Ban. Thereby, it is possible to prevent an erroneous setting due to not knowing that the state has changed due to the operation of the other operation device when operated almost simultaneously.

  The system derived from this embodiment is the same as the contents described in the first and second embodiments. In addition, in this embodiment, the button color is changed when the operation is temporarily prohibited. However, any display may be used as long as the operation is prohibited. Although a case where a predetermined time has passed as a condition for canceling the operation prohibition, a modification such as newly providing a cancel button is also possible.

  In the illustrated embodiment, the other operating device 1 is connected to the pan / tilt head photographing device 2 via the own operating device 1, but the present invention is not limited to this. A configuration in which a plurality of operating devices are directly connected to the pan / tilt head photographing device, and the pan / tilt head photographing device transmits / receives a connection state of other operating devices, an operating state, a state of the photographing device itself, etc. to / from the plural operating devices. Even so, the effects of the present invention can be enjoyed.

  In the illustrated embodiment, the other operation device 1 is connected to the pan / tilt head photographing device 2 via the self-operation device 1. However, the present invention is not limited to this. Even if the self-operating device is connected to the pan / tilt head imaging device via another operating device, and the other operating device is not in use and inoperable, the self-operating device and the cloud via the other operating device The effect of the present invention can be enjoyed in the same manner even in a configuration in which communication between the table photographing devices is possible.

  In the illustrated embodiment, the connection between the operation unit and the pan / tilt head photographing apparatus is described as a wired connection. However, the present invention is not limited to this, and the same effect can be obtained even by a wireless connection.

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