Details of the embodiment of the present invention will be described below.
(First embodiment)
A representative view of this embodiment is shown in FIG.
FIG. 1 is a block diagram illustrating details of a monitoring camera system including a monitoring camera (camera server) 100 and a viewer client (control device) 200.
The surveillance camera (imaging device) 100 includes a CPU 110, a primary storage device 120, a secondary storage device 130, a video capture I / F 140, a control I / F 150, and a network I / F 190 via an internal bus 180. It is connected.

An image capturing unit 145 is connected to the video capture I / F 140, and image data captured by the image capturing unit 145 is converted and compressed into a predetermined format and transferred to the primary storage device 120.
The pan / tilt head 155 is connected to the control I / F 150, and the pan / tilt mechanism / rotation mechanism / zoom mechanism state of the pan / tilt head 155 is obtained, or the pan head 155 is controlled in accordance with an operation instruction. I do.

  The network I / F 190 is output like a conventional CCTV camera and connected to a recording device such as a DVR, or communicates with various clients via a communication medium such as Ethernet (registered trademark) as a network camera. I / F to carry out.

In the viewer client (control device) 200, a CPU 210, a primary storage device 220, a secondary storage device 230, a keyboard 240, a mouse 250, a display 260, and a network I / F 290 are connected to each other via an internal bus 280. .
The primary storage device 220 is the same as the primary storage device 120 of the monitoring camera 100.
The secondary storage device 230 is the same as the secondary storage device 130 of the monitoring camera 100.
A general input device for giving instructions is connected to the keyboard 240 and the mouse 250.
A general output device for displaying is connected to the display 260.
The network I / F 290 is an I / F for connecting to the network 195, and is similar to the network I / F 190 of the monitoring camera 100, so that it can be connected to the network I / F 190 mutually. is there. In the present embodiment, a panning / tilting / zooming control is realized by processing a video by processing a first input unit that inputs a first instruction for panning / tilting / zooming control of the pan / tilt head 155. It functions as a second input unit for inputting a second instruction for the purpose.

Here, as shown in FIG. 2, an imaging program 300, a pan head control program 310, and a delivery program 320 are loaded into the primary storage device 120 of the camera server 100 (surveillance camera).
The secondary storage device 130 of the camera server 100 stores a plurality of PTZ (pan / tilt / zoom) data 370, a movable range value 380, imaging data 390, and the like.

As shown in FIG. 2, a communication program 400, a display program 410, and operation programs 420 to 424 are loaded on the primary storage device 220 of the viewer client (control device) 200.
Also, delivery data 490 and the like are stored in the secondary storage device 230 of the viewer client 200 in FIG.

  The imaging program 300 processes the video from the imaging unit 145 with the video capture I / F 140 and holds the processed imaging data 390 in the secondary storage device 130. The storage destination may be not only the secondary storage device 130 but also a high-speed storage device such as the primary storage device 120 or a buffer. Since this is a general video image processing and is a conventional technique, a detailed description is omitted.

  The pan head control program 310 receives instructions from various programs, controls the pan head 155 from the control I / F 150, receives information from the pan head 155, and processes it by a device I / F (not shown). This is notified or held in the secondary storage device 130. The storage destination may be not only the secondary storage device 130 but also a high-speed storage device such as the primary storage device 120 or a buffer. This is a general pan / tilt head-driven camera control process, which is a conventional technique, and therefore will not be described in detail.

  The communication program 400 receives a video delivery described later by the network I / F 290 from the camera server 100 via the network 195 and stores it as delivery data 490 in the secondary storage device 230. This is a general communication process, particularly a video reception process, and is a conventional technique, and thus detailed description thereof is omitted.

  The display program 410 updates and displays the image on the viewer displayed on the display 260 when the delivery data 490 of the secondary storage device 230 is updated. This is a conventional technique for general display processing, and will not be described in detail, but an example of a displayed viewer is shown in a viewer 31 in FIG.

Next, an example of a processing procedure performed by the delivery program 320 is shown in the flowchart of FIG.
In S401, the plural PTZ data 370 and the movable range value 380 are read and an initialization process is performed. The multiple PTZ data 370 of the present embodiment has values of a physical PTZ first and an electronic PTZ second. For example, the physical PTZ is represented by polar coordinates such as an angle of view of 0 to 180 degrees with a front angle as the origin and an imaging angle of view centered around the pan direction ± 180 degrees and the tilt direction ± 90 degrees. In addition, an electronic PTZ having a width W and a height H in which the upper left coordinate is defined by the coordinate of resolution X × Y with the upper left of the image of the imaging field angle as the origin is represented.

In S402, an event is waited for. If there is an event, the process proceeds to S410.
In S410, it is determined whether imaging data 390 has been updated. If it has been updated, the process proceeds to S411, and if it has not been updated, the process proceeds to S420.
In S411, it is determined whether or not electronic PTZ is designated. Second electronic PTZ control (second electronic pan / tilt / zoom control) for electronic panning / tilting / zooming, and second electronic PTZ operation (second electronic) Pan / tilt / zoom operations). If the electronic PTZ is designated, an image obtained by cutting out the imaged data 390 is distributed in S412. If the electronic PTZ is not designated, the imaging data 390 is delivered as it is in S413. In S402, an event is waited. The electronic PTZ can also be executed as a cutout in the viewer client (control device) 200.

In S420, it is determined whether there is a setting inquiry event. If there is a setting inquiry event, the process proceeds to S421, and if there is no setting inquiry event, the process proceeds to S430.
In S421, multiple PTZ data 370 and movable range value 380 are returned. Thereafter, an event is waited at S402.
In S430, it is determined whether or not there are multiple PTZ setting events. If there are multiple PTZ setting events, the process proceeds to S431, and if not, the process proceeds to S490.

In S431, multiple PTZ data 370 is set. Thereafter, an event is waited at S402. The multiple PTZ setting event is a request between general networks realized by, for example, an http request, and does not specifically control the camera server by limiting the client.
In S490, it is determined whether an end event has been received. When receiving the end event, the delivery program 320 ends. If no end event is received, an event is awaited in S402.

Next, an example of a processing procedure performed by the operation program 420 of this embodiment is shown in the flowchart of FIG.
In S501, a setting inquiry is made to the delivery program 320 of the camera server (surveillance camera) 100, and a plurality of PTZ data 370 and a movable range value 380 are obtained to perform initial setting.
Specifically, like the operation panel 32 shown in FIG. 3, a movable range frame 33 indicating a movable range, a physical PTZ frame 34 indicating a physical PTZ state, and an electronic PTZ frame 35 indicating an electronic PTZ state are displayed on the display 260. To do. For example, in the movable range display, a rectangle 33 in which polar coordinates are mapped to the two-dimensional coordinates “(−180, +90) − (+ 180, −90)” is displayed, and the angle of view is displayed at the position of the physical PTZ. A rectangle 34 is placed, and an electronic PTZ rectangle 35 is placed in the rectangle 34 and displayed.
If the panorama image obtained by photographing all the conventional movable ranges is displayed in the movable range rectangle 33, the situation is easier to understand.

In S502, an event is awaited. If there is an event, the process proceeds to S510.
In S510, it is determined whether or not the frame 34 corresponding to the physical PTZ has been operated by an interface such as the mouse 250 or the keyboard 240 of the viewer client 200. If not operated, the process proceeds to S520. When the operation is performed, the process proceeds to S511, and the frame 34 is activated and the rectangle is moved or deformed in accordance with general GUI processing. As described above, by moving and deforming the frame 34 corresponding to the physical PTZ, an operation result of the mouse 250 or the like that operates the frame 34 is displayed.
Proceeding to S 512, the physical PTZ value calculated by the coordinates indicated by the subsequent frame 34 is sent to the server 100 as a plurality of PTZ setting events. Thereafter, an event is waited in S502.

In S520, it is determined whether or not the frame 35 corresponding to the electronic PTZ has been operated by the interface as in S510. If not operated, the process proceeds to S580. When operated, the frame 35 is activated and the rectangle is moved or deformed in accordance with general GUI processing in S521. In this way, by moving and deforming the frame 35 corresponding to the electronic PTZ, the second electronic pan / tilt / zoom operation result of the mouse 250 or the like operating the frame 35 is displayed.
Proceeding to S522, the value of the electronic PTZ calculated by the coordinates indicated by the subsequent frame 35 is sent to the server 100 as a plurality of PTZ setting events. In step S502, an event is awaited.

  In S580, it is determined whether or not a new operation for drawing a rectangle has been performed. If not performed, the process proceeds to S590, and if a new operation for drawing a rectangle is performed, the operation is performed by regarding the frame activated in S581 as a target. For example, when the physical PTZ frame 34 is activated in S511, the physical PTZ frame 34 is newly drawn.

  Thereafter, the process proceeds to S582, and the other frame is drawn by a predetermined method. For example, when the physical PTZ frame 34 is newly drawn in S581, the electronic PTZ frame 35 is drawn with a predetermined size inside the center. Alternatively, when the electronic PTZ frame 35 is newly drawn in S581, the physical PTZ frame 34 is drawn at a predetermined size on the outer side where it is placed at the center.

Thereafter, in S583, the physical PTZ value and the electronic PTZ value calculated by the coordinates indicated by the frame 34 and the frame 35 are sent to the server 100 as a plurality of PTZ setting events by a conventional GUI method. Thereafter, an event is waited in S502. The electronic PTZ can also be executed as a cutout in the viewer client (control device) 200.
In S590, it is determined whether an end event has been received. When the end event is received, the operation program 420 ends. If no end event is received, an event is awaited in S502.

From the above, the camera platform 155 of the server 100 is controlled by the rectangle operated on the operation panel 32, and the subsequent imaging data 390 is delivered to the viewer client 200 as delivery data 490, and is displayed to the viewer 31 by the display program 410. Is displayed.
In this way, the viewer performs the first control, which is physical PTZ control that performs physical pan / tilt / zoom control, and the second control that realizes pan / tilt / zoom control by processing an image. 31 can be displayed. Thereby, the first operation result of the first control and the second operation result of the second control can be displayed on the viewer 31. Accordingly, it is possible to perform pan / tilt / zoom driving while displaying the state within the movable range, and the operation can be made clear even with a plurality of PTZ driving systems.

(Second Embodiment)
In the first embodiment, a plurality of PTZ drive systems are provided in the camera server (surveillance camera) 100, but may be included in a system including a viewer client (control device) 200. The configuration diagram of the system of this embodiment is the same as FIG. 1 of the first embodiment.

  Further, an example is shown in which the cutout program 430 is activated on the primary storage device 220 having the system configuration, and the display program 411 is activated instead of the display program 410 of the first embodiment. In addition, an example in which the cutout data 480, the cutout range value 470, and the cutout position 460 are generated in the secondary storage device 230 is shown.

The display example of the second embodiment is the same as the display example of FIG. 3, but the frame 35 is a cutout frame 35 that indicates the cutout state of the viewer 31 of the viewer client 200.
The display program 411 is almost the same as the display program 410 of the first embodiment, and the handled data is changed from the delivery data 490 to the cut-out data 480. That is, when the cut-out data 480 of the secondary storage device 230 is updated, the image on the viewer displayed on the display 260 is updated and displayed. Since this is a conventional technique for general display processing, detailed description thereof is omitted.

Next, the flow of processing of the operation program 421 of this embodiment will be described.
The operation program 421 is substantially the same as the operation program 420 of the first embodiment, and the processes in steps equivalent to S501, S522, and S583 in the flowchart of FIG. 5 described above are different.
In a step equivalent to S501 of the operation program 421, a setting inquiry is made to the delivery program 320 of the camera server 100 to obtain physical PTZ data 370 and a movable range value 380. Further, the cut-out range value 470 is read from the secondary storage device 230, and initial setting is performed.

  In the second embodiment in which the operation program 421 is activated, the cutout frame 35 is operated in a step equivalent to S522 in the flowchart of FIG. 5 described above. Thereby, the second cutout control for cutting out the video electronically is performed. Then, the value of the cut position calculated by the coordinates indicated by the cut frame 35 is sent to the cut program 430. Thereafter, the process waits for an event in the same step as S502.

  In the second embodiment in which the operation program 421 is activated, the value of the cutout position calculated by the coordinates indicated by the cutout frame 35 is sent to the cutout program 430 in a step equivalent to S583 in the flowchart of FIG. Is done. Thereafter, the process waits for an event in the same step as S502.

Next, an example of a processing procedure performed by the cutout program 430 of this embodiment is shown in the flowchart of FIG.
In S601, the cutout range value 470 and the like are read and initialization is performed. Thereafter, an event is waited in S602, and if there is an event, the process proceeds to S610.
In S610, it is determined whether delivery data 490 has been updated. If the delivery data 490 has not been updated, the process proceeds to S620. If it has been updated, the process advances to step S611 to determine whether or not there is a cutout position 460. If there is a cutout position 460, the process proceeds to S612, where the delivery data 490 is cut out and the cutout data 480 is updated.

If the cutout position 460 is not set as a result of the determination in S611, the process proceeds to S613, and the delivery data 490 is copied to the cutout data 480 as it is. Thereafter, an event is waited in S602.
Here, the data of the cut-out position 460 is realized by a value representing an electronic PTZ having a width W and a height H in which the upper left coordinate is defined by the coordinates of resolution “X × Y” with the upper left corner of the image of the imaging angle of view as the origin. The

In S620, it is determined whether or not there is a cut position value setting event. If there is no cut position value setting event, the process advances to step S690. If there is a setting event, the process proceeds to S621, and the cutout position 460 is updated. When canceling the cutout position, the cutout position 460 is deleted. Thereafter, the process proceeds to S602 and waits for an event.
In S690, it is determined whether an end event has been received. When the end event is received, the cutout program 430 ends. If no end event is received, an event is awaited in S602.
In this way, the operation can be clarified even with a plurality of PTZ drive systems such as the physical PTZ of the camera server 100 and the cutout by the viewer 31 of the viewer client 200.

(Third embodiment)
In the first embodiment and the second embodiment, the plurality of PTZ drive systems are two PTZ drive systems, but there may actually be three or more.
The system configuration diagram of this embodiment is the same as that of the first embodiment.
Further, the operation program 422 is activated on the primary storage device 220 having the system configuration instead of the operation program 420 of the first embodiment.

  FIG. 3B showing a display example of the third embodiment further includes a frame 36 inside the frame 35 of the display example of FIG. For example, a physical PTZ frame 34 indicating a physical PTZ state, an electronic PTZ frame 35 indicating an electronic PTZ state, and a cutout frame 36 indicating a cutout state are provided.

Next, the process flow of the operation program 422 of this embodiment will be described with reference to the flowchart of FIG.
The operation program 422 is different from the operation program 420 of the first embodiment in that operations S730 to S732 for the operation of the frame 36 are added, and the processing corresponding to steps S582 and S583 is different.
S701 to S722 and S780, S781, and S790 are equivalent to S501 to S522, S580, S581, and S590, respectively.

In S702, when an operation event of the frame 36 is performed while waiting for an event, the process proceeds to S730.
In S730, it is determined whether or not the frame 36 corresponding to clipping has been operated by the interface in the same manner as in S510 and S520. If not operated, the process proceeds to S780, and if operated, the process proceeds to S731. In S731, following the general GUI processing, the frame 36 is activated, and the rectangle is moved or deformed. As described above, by moving and deforming the frame 36 corresponding to the cut-out, the operation result of the mouse 250 or the like operating the frame 36 is displayed.
In S <b> 732, the value of the cutout position calculated by the coordinates indicated by the subsequent frame 36 is sent to the cutout program 430. Thereafter, an event is waited in S702. As a result, it is possible to realize a third operation for performing the third cutout control for electronically cutting out the displayed video and the third cutout operation for operating the third cutout control.

Similar to S580 and S581 of the first and second embodiments, when a new rectangle is drawn, the processing of S780 and S781 is performed, and the process proceeds to S782.
In S782, an inactive frame is drawn by a predetermined method. For example, when the physical PTZ frame 34 is newly drawn in S781, the electronic PTZ frame 35 is drawn with a predetermined size inside the center, and the cutout frame 36 is drawn with a predetermined size inside the center. Is done.

  Alternatively, when the electronic PTZ frame 35 is newly drawn in S781, the physical PTZ frame 34 is drawn in a predetermined size on the outer side where the electronic PTZ frame 35 is placed in the center, and the cutout frame 36 is previously set on the inner side of the electronic PTZ frame 35. Rendered at a defined size.

  Alternatively, when the cutout frame 36 is newly drawn in S781, the electronic PTZ frame 35 is drawn in a predetermined size on the outside where the cutout frame 36 is placed in the center, and the physical PTZ frame 34 is drawn in advance on the outside where it is placed in the center. Rendered at a defined size.

  Thereafter, the process proceeds to S783, and the physical PTZ value and the electronic PTZ value calculated by the coordinates indicated by the frame 34 and the frame 35 are obtained by the GUI method similar to that of the first embodiment and the second embodiment. Sent as multiple PTZ setting events. Further, the value of the cutout position calculated by the coordinates indicated by the frame 36 is sent to the cutout program 430. Thereafter, an event is waited in S702.

  In this way, the operation can be clarified even with three PTZ drive systems such as the physical PTZ and electronic PTZ of the camera server 100 and the cutout by the viewer 31 of the viewer client 200.

(Fourth embodiment)
In the first embodiment to the third embodiment, the operations of the plurality of PTZ drive systems are performed without limitation. However, more preferable and clear operations can be provided by limiting the operations.
The system configuration diagram of this embodiment is the same as that of the first embodiment. In addition, the operation program 423 is activated instead of the operation program 422 of the third embodiment on the primary storage device 220 having the system configuration.

Next, the flow of processing of the operation program 423 of this embodiment will be described (not shown).
The operation program 423 differs from the processing of S721 and S731 in the flowchart of FIG. 7 for explaining the processing of the operation program 422 of the third embodiment.
In the operation program 423 of the present embodiment, the processing similar to S721 is limited to only the area inside the frame 34 corresponding to the physical PTZ when the frame 35 corresponding to the electronic PTZ is operated. When an attempt is made to operate the frame 35 outside the frame 34 by a conventional GUI method, a predetermined process is performed so as to prohibit the operation of the area outside the frame 34. For example, processing such as sounding a warning sound, invalidating the operation, or setting a frame 35 corresponding to the electronic PTZ in the center of the frame 34 corresponding to the physical PTZ is performed.

  In the case of the operation program 423 of the present embodiment, the same processing as S731 is the same as the processing of S721 of the present embodiment, and when the frame 36 corresponding to clipping is operated, the frame corresponding to the electronic PTZ is processed. It is limited to the area inside 35. When an attempt is made to operate the frame 36 outside the frame 35 by a conventional GUI method, a predetermined process is performed. For example, processing such as sounding a warning sound, invalidating the operation, or setting a frame 36 corresponding to the cutout in the center of the frame 35 corresponding to the electronic PTZ is performed. In other words, when the electronic pan / tilt / zoom or cutout is out of the physical pan / tilt / zoom range, or when the cutout is out of the electronic pan / tilt / zoom range, an overhang operation is attempted. Notify when. Also, the operation is prohibited so as not to be operated when an overhang operation is attempted.

In the present embodiment, three PTZ drive systems have been described as in the third embodiment. However, the present embodiment may be implemented by two PTZ drive systems as in the first and second embodiments. Further, it may be realized by three or more drive systems.
By doing so, the operation can be limited so that the frame 35 is included in the frame 34 and the frame 36 is included in the frame 35, and the operation can be clarified even in a plurality of PTZ operation systems.

(Fifth embodiment)
In the first to fourth embodiments, the operations of the plurality of PTZ drive systems are always clearly displayed, but can be displayed as necessary.
The system configuration diagram of this embodiment is the same as that of the first embodiment. Further, on the primary storage device 220 having the system configuration, an operation program 424 is activated instead of the operation program 420 of the first embodiment.

  A display example of the fifth embodiment is shown in FIG. In addition to the display examples of FIGS. 3A and 3B of the first to fourth embodiments, a switching button 38 is added, and when the switching button 38 is operated, the display mode of the operation panel 32 is switched, and the frame 37 Is displayed. Further, when the switching button 38 is operated, the original display mode is restored.

Next, the processing flow of the operation program 424 of this embodiment will be described with reference to the flowchart of FIG.
In step S901, initialization is performed in the same manner as in step S501, and the display is performed in a mode in which, for example, the physical PTZ frame 34 and the electronic PTZ frame 35 are enabled as the default display mode.
In S902, the process waits for an event. If there is an event, the process proceeds to S910.
S910 to S922 are the same as S510 to S522 of the operation program 420 of the first embodiment.

In S940, it is determined whether or not the frame 37 has been operated by the interface in the same manner as in S910 and S920. When the frame 37 is operated by the interface, the process proceeds to S941.
In S941, the rectangle of the frame 37 is moved or deformed following general GUI processing. Proceeding to S942, the physical PTZ value and the electronic PTZ value determined by a predetermined calculation method are sent to the server 100 as a plurality of PTZ setting events according to the coordinates indicated by the frame 37 thereafter. Thereafter, an event is waited for in S902.

  At this time, the predetermined method is, for example, if the physical PTZ is within the movable range value 380 of the physical PTZ drive system, the physical PTZ is given priority and the electronic PTZ is not used. Then, a method of using the electronic PTZ together when zooming beyond the movable range value 380 of the physical PTZ drive system may be determined in advance.

In S950, it is determined whether or not the switching button 38 has been pressed. If the switch button 38 is not pressed, the process proceeds to S980. If the switch button 38 is pressed, the process proceeds to S951 to determine the display mode.
As a result of the determination in S951, if the frame 37 is in an invalid display mode, the process proceeds to S952, where it is switched, the frames 34 and 35 are invalidated, and the frame 37 is validated. When the frame 34 and the frame 35 are invalidated, the event is not processed in S910 or S920 because the frame 34 and the frame 35 are inactivated and hidden.

If the frame 37 is in an effective display mode, the process proceeds to S953 to switch it, enabling the frame 34 and the frame 35 and disabling the frame 37. When disabling the frame 37, the event is not processed in S940 because the frame 37 is inactivated and hidden.
Thereafter, the process returns to S902 and waits for an event.

In S980, it is determined whether or not a new operation for drawing a rectangle has been performed. If a new operation for drawing a rectangle has not been performed, the process proceeds to S990, and if it has been performed, the process proceeds to S981.
In S981, the activated frame is regarded as a target and operated.
Thereafter, in S982, an inactive frame is drawn by a predetermined method. For example, when the physical PTZ frame 34 is newly drawn in S981, the electronic PTZ frame 35 is drawn with a predetermined size inside the center.

Alternatively, when the electronic PTZ frame 35 is newly drawn in S981, the physical PTZ frame 34 is drawn at a predetermined size on the outside where the electronic PTZ frame 35 is placed at the center.
Thereafter, in S983, the physical PTZ value and the electronic PTZ value calculated by the coordinates indicated by the frame 34 and the frame 35 are sent to the server 100 as a plurality of PTZ setting events by a conventional GUI method. Thereafter, an event is waited for in S902.

When the frame 37 is newly drawn in S981, the other inactive frames are not drawn in S982, and the physical PTZ value and the electronic PTZ value are set in a predetermined method similar to S942 in S983. It is sent to the server 100 as a plurality of PTZ setting events. Thereafter, an event is waited for in S902.
When the end event is received in S990, the operation program 424 ends.

  Switching between a plurality of controls for controlling a plurality of PTZ drive systems in a predetermined method, a single independent operation for operating the plurality of controls, a plurality of controls, and a first control to a third plurality of controls. Thus, one display / operation and a plurality of display / operations can be switched. By doing this, it is possible to switch between the display / operation by the frame 37 that is not conscious of the multiple PTZ drive system and the display / operation of the frame 34 and the frame 35 that display the status of the multiple drive system, and perform a suitable operation. Can do.

  In the present embodiment, the modification of the first embodiment has been described. However, a switch button 38 is prepared for the operations of the second to fourth embodiments, and an operation and a plurality of operations that are not conscious of a plurality of PTZ drive systems. The operation for displaying the drive system may be switched.

By doing so, for example, when the user desires delivery in a narrow band, it is possible to check whether the data amount can be reduced by using the electronic PTZ cut out on the camera side as much as possible.
In addition, for example, when the user desires high image quality on the viewer client 200 side, the delivery data 490 can be made high image quality by using the physical PTZ without cutting out the image obtained in the frame 37 as much as possible on the camera side. You can check whether or not

  In the first to fifth embodiments described above, the example in which the operation programs 420 to 424 are held in the primary storage device 220 has been shown. However, all of these programs need to be held. There is no. It is only necessary to hold one operation program or a plurality of programs. The same applies to the cutout program 430 that is not used in the first embodiment, and may not necessarily be held.
