Description

  The present invention relates to an imaging controller, and more particularly to an imaging controller that performs a pan head operation.

  Conventionally, surveillance cameras and the like are controlled by remote operation from an operating device located away from the camera. In order to obtain desired shooting conditions, various control modes can be set and operated from the operating device.

  When shooting a video, it is necessary to operate the controller while watching the video. At that time, a hard member such as a joystick or a hard switch is used in the operation device in order to prevent erroneous operation. It becomes easy to operate by assigning a dedicated function to the hard member.

  In recent years, a soft switch operation on a GUI using a touch panel has been widely used due to an increase in the speed of software processing resulting from an improvement in CPU performance. In this case, the touch panel is formed integrally with a display unit that displays a GUI. Therefore, the soft switch screen is configured on the display unit of the touch panel, and the pressing of the display unit is detected by the touch panel, so that the soft switch screen is also used as the operation unit. Since the soft switch can be freely configured on the screen, the switch configuration can be changed for each operation target. As the operation device, one using a touch panel as an operation unit is known. For example, Patent Document 1 discloses a technique for performing an operation with a hard member and a touch panel.

  In addition, in an operating device using a touch panel, the status of the operation target is also displayed on the touch panel of the operating device. For example, Patent Document 2 discloses a technique for displaying a setting value designated by a user by providing a display area for displaying a state on a touch panel of an operating device.

JP 2014-38285 A JP 2003-101837 A

  However, in the operation device configured to perform the operations of both the hard member and the touch panel disclosed in Patent Document 1 described above, the housing cannot be enlarged when there is a restriction on the installation location. The area of the part is limited. In particular, since the touch panel also serves as a display unit, the display area is narrowed. Since the area of the display unit is limited, it is difficult to display the state of the operation target if the GUI of the display unit displays a soft switch while operating the hard member. For this reason, it is difficult to confirm the state of the operation target when both the hardware member and the touch panel are operated.

  Moreover, in the prior art disclosed in Patent Document 2 described above, the display is limited to only the information specified by the user. Since information to be displayed is determined in advance, correspondence with operations at the time of shooting is limited to only a part of functions. Therefore, display according to the operation content cannot be performed efficiently.

  Therefore, an object of the present invention is to shoot images in which setting values can be confirmed while performing operations by efficiently displaying items whose settings have been changed according to the operation of the operation device on a touch panel even in a limited display area. Is to provide a controller.

  In order to achieve the above object, the present invention includes a touch panel that also serves as a display unit and a first operation unit, and a second operation unit configured by a hard member, and the display unit is configured to perform a first or second operation. A setting value display area for displaying an item related to the operation and a setting value of the item in a setting value display area according to a result of operating the unit, and displaying the setting value display area according to the operation It is characterized by changing.

  According to the present invention, there is provided a photographing controller capable of confirming a set value while performing an operation by efficiently displaying an item whose setting is changed according to the operation of the operation device on a touch panel even in a limited display area. Can be provided.

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

[Example 1]
Hereinafter, a first embodiment of the photographing controller of the present invention will be described. FIG. 1 shows a connection example of an imaging system for remotely operating a pan head 2 using an operating device 1 that is an imaging controller according to an embodiment of the present invention. The pan / tilt head 2 (photographing device) is provided with a pan / tilt drive unit, and a camera 21 and a lens 22 are mounted. When the user operates the operation unit of the operation device 1, a control command corresponding to the operation is transmitted to the camera platform 2. Further, state information indicating the current state of the camera platform 2 (for example, position information of an operation target corresponding to a control command from the operation device) is transmitted from the camera platform 2 to the operation device 1. Then, the operating device 1 updates the setting value of the management item stored in the operating device 1 based on this state information.

  The operation unit (operation means) of the operation device 1 is preferably configured with a zoom lever 13, a focus encoder 14, a joystick 15, a touch panel 16, a hard switch 17, and the like as illustrated. 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 camera platform 2 can be performed by operating the joystick 15 forward / backward / left / right.

  FIG. 2 is a block diagram illustrating an internal configuration of the operation device 1 according to the first embodiment. In addition to the above-described operation unit, the operation device 1 includes communication ports 11 and 12, a communication unit (communication unit) 101, a CPU (control unit) 102, a display processing unit 103, a storage unit 104, an operation recognition unit 105, and a setting value display. An area change unit 106 and a state information recognition unit 107 are included. When the user 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 CPU 102 recognizes the operation content, the CPU 102 outputs a control command corresponding to the operation to the communication unit 101.

  The communication unit 101 transmits the control command notified from the CPU 102 to the camera platform 2 connected via the communication port 11. Further, the CPU 102 outputs to the display processing unit 103 contents corresponding to the operation state of the operation unit notified from the operation recognition unit 105 and the state information of the external device received via the communication port 11. The display processing unit 103 controls display on the touch panel 16 in accordance with an input from the CPU 102. The setting value display area 162 in the touch panel 16 is displayed by the setting value display area changing unit 106 and the state information recognition unit 107. The status information recognition unit 107 acquires the status information of the camera platform 2 received via the communication port 11.

  When it is necessary to change the display of the set value display area 162, the set value display area changing unit 106 outputs the set value to be displayed via the CPU 102 to the display processing unit 103 to control the display. In addition, it has a storage unit 104 for storing various setting information and the like.

  FIG. 3 shows an example of a screen configuration displayed on the touch panel 16. The touch panel 16 has a function as a display unit for displaying a state and a function as an operation unit for displaying a soft button on the screen. A plurality of buttons and text representing their functions are displayed on the screen of the touch panel 16. The touch panel 16 is provided with a soft switch display area 161 and a set value display area 162 when the touch panel is operated. In the soft switch display area 161, the camera platform 2 can be operated by pressing each soft switch. Further, by displaying the operation content of the operating device 1 in the setting value display area 162, the user is notified that the setting value of the pan head 2 has been changed.

  Next, the processing flow of the CPU 102 when changing the set value display area 162 of the operation device 1 will be described based on the flowchart of FIG.

  First, the CPU 102 confirms whether or not the operation unit 1 has acquired the operation of the operation unit 1 in step S101. If the operation is not acquired, the process ends here. On the other hand, if an operation is acquired in step S101, the process proceeds to step S102, where the operation content is processed and transmitted to the pan head 2. After transmission, it waits in step S103, and obtains status information from the camera platform for the transmission content. When the status information is received from the camera platform in step S103, the process proceeds to step S104, and the setting value related to the camera platform managed in the controller is changed based on the received data.

  Then, the number of set values changed in step S105 is calculated. As a result of step S105, if there is one changed setting value, the setting value changed in step S106 and the setting value of the item related to the setting value are displayed in the setting value display area 162. FIG. 5 shows a display example of the set value display area 162 on the touch panel 16 in step S106. FIG. 5 is a display example when the gain is changed by operating the operation unit 1. When the brightness of the video imaged by the gain is changed, setting values for the shutter and iris, which are items related to the brightness, are also displayed in the setting value display area 162. The display of related items is the number of items that can be displayed simultaneously in the set value display area 162. If there is no related item, only the item operated by the controller 1 is displayed.

  On the other hand, when it is determined in step S105 that the plurality of setting values of the camera platform 2 have been changed by operating the operating device 1, the operation content of the operating device 1 is displayed in the setting value display area 162 in step S107. FIG. 6 shows a display example of the set value display area 162 on the touch panel 16 in step S107. FIG. 6 shows a display example when presetting is performed by operating the operation unit 1. The preset is changed to the saved values of pan, tilt, zoom, and focus. Since it is difficult to display all the change items at the same time in the setting value display area 162, the preset number as the operation content is displayed.

  As described above, when the pan head 2 is operated by the operation unit 1, the items displayed in the setting value display area 162 are changed depending on whether one or more setting values are changed. The setting value changed efficiently can be displayed. Thereby, it becomes possible to automatically confirm the item changed by the control command from the operation device 1 and the set value of the item related to the item.

  Regarding the internal structure of the operation device 1, the CPU 102 and other functions are divided into blocks. For example, the CPU 102 has a communication unit 101, a display processing unit 103, a storage unit 104, an operation recognition unit 105, a set value display area change unit 106, The function of the state information recognition unit 107 may also be used.

[Example 2]
The second embodiment of the present invention will be described below. FIG. 7 is a block diagram showing an internal configuration of the operation device 1 which is a photographing controller according to the second embodiment of the present invention. Compared with the configuration of the first embodiment shown in FIG. 3, the configuration of FIG. 7 includes an operation time measuring unit 108. The operation time measuring unit 108 identifies when a plurality of processes are performed within a certain time or when no processes are performed at all, and sends information to the set value display area changing unit 106. Thereby, the setting value display area changing unit 106 determines the setting value to be displayed in the setting value display area 162.

  Next, the processing flow of the CPU 102 when changing the set value display area 162 of the operation device 1 will be described based on the flowchart of FIG.

  First, it is confirmed in step S201 whether a pan / tilt / zoom operation has been acquired. Here, when these operations are not mastered, this processing is terminated. On the other hand, when the pan / tilt / zoom operation is acquired in step S201, the operation content is processed in step S202, and the operation content is transmitted to the pan head. Thereafter, the process waits in step S203, and obtains status information from the camera platform for the transmission contents. When the status information is received from the camera platform in step S203, the process proceeds to step S204, and the setting value related to the camera platform managed in the controller is changed based on the received data. Next, in step S205, it is confirmed whether another operation has been acquired.

  Here, the processing flow of the CPU 102 when acquiring other operations will be described based on the flowchart of FIG. 9.

  First, in step S301, the operation of the operating device is acquired. In step S302, it is determined whether the operation is other than pan / tilt / zoom. Here, if the acquired operation is pan / tilt / zoom, this processing is terminated. On the other hand, if the acquired operation is an operation other than pan / tilt / zoom, the process proceeds to step S303. In step S303, the operation acquired in step S301 of this process is saved.

  By saving the operation acquired here, it is possible to identify whether another operation is acquired. After saving the operation, the process proceeds to step S304 and waits until a predetermined time elapses. If pan / tilt / zoom operations are acquired during this period, it is considered that other operations and pan / tilt / zoom operations are operated simultaneously. When the fixed time has elapsed, the process proceeds to step S305, where the stored operation content is discarded. By performing this processing, it is possible to identify that other operations and pan / tilt / zoom operations are performed simultaneously.

  Here, it returns to the flowchart of FIG. Next, in step S206, it is determined whether another operation other than pan / tilt / zoom has been acquired. If it is determined that the simultaneous operation has been performed by acquiring other operations, the process proceeds to step S207. On the other hand, if no other operation has been acquired, the process proceeds to step S209. In step S207, it is determined whether the acquired pan / tilt / zoom values are within a preset threshold range. As the threshold value, two threshold values, an upper limit and a lower limit, are set for each value of pan / tilt / zoom. If it is determined in step S207 that the pan / tilt / zoom value is within the threshold, the process proceeds to step S208.

  On the other hand, if the threshold value is exceeded, the process proceeds to step S209. In step S208, other operation information is displayed in the set value display area 162. Display examples are the same as those in FIGS. 5 and 6 shown in the first embodiment. In step S209, pan / tilt / zoom information is displayed. A display example in this case is shown in FIG. Since the zoom is set near the telephoto end, the zoom display is given priority.

  As described above, by setting a threshold value for each value of pan / tilt / zoom, operation information displayed in the set value display area 162 when pan / tilt / zoom and other operations are performed simultaneously is changed. be able to. When the pan / tilt / zoom is within the threshold, other operation information is displayed in the set value display area 162, and when the pan / tilt / zoom exceeds the threshold, the pan / tilt / zoom value is displayed in the screen of the touch panel 16. It is possible to display operation information with high priority. Thereby, even when a plurality of control commands are issued simultaneously from the controller 1, it is possible to automatically confirm the operation content having a high priority.

[Example 3]
The third embodiment of the present invention will be described below. The block diagram showing the internal configuration of the operating device 1 which is a photographing controller according to the third embodiment is the same as FIG. 7 shown in the second embodiment. A processing flow of the CPU 102 when changing the set value display area 162 of the operating device 1 will be described based on the flowchart of FIG.

  First, in step S401, it is determined whether an operation has been performed within a certain time. If so, the process is terminated. On the other hand, if not, the process proceeds to step S402. In step S402, the zoom setting value is confirmed. In step S403, it is determined whether the zoom position is at the telephoto end. As a result, if it is not at the telephoto end, this processing is terminated. On the other hand, if it is at the telephoto end, the process proceeds to step S404. In step S404, the zoom-related set value is displayed in the set value display area 162. A display example in that case is shown in FIG. In this figure, the zoom position and the state of the digital extender are displayed in the set value display area 162. In addition, the digital zoom magnification may be displayed.

  As described above, the zoom-related set value is displayed in the set value display area 162 when the zoom position is at the telephoto end. Thus, even when the zoom position is at the telephoto end, it is possible to notify the user that zoom-related operations are possible by performing operations such as changing the magnification of the digital extender, and assist the zoom operation. Therefore, it becomes possible to automatically confirm the set values and operation details required when no control command is issued from the controller 1.

  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.
