<Embodiment 1>
The system configuration is shown in FIG.

  FIG. 1 is a block diagram illustrating a configuration of a camera system including a camera server 100 and a client 200 that function as information processing apparatuses.

  The camera server 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, a device I / F 160, and a network I / F 190. Various components of the camera server 100 are connected to each other via an internal bus 180.

  The primary storage device 120 is a writable high-speed storage device represented by a RAM, and is loaded with an OS, various programs, and various data under the control of the CPU 110, and also used as a work area for the OS and various programs. Is done. The secondary storage device 130 is a nonvolatile storage device represented by FDD, HDD, flash memory, CD-ROM drive, etc. In addition to being used as a permanent storage area for the OS, various programs, and various data, It is also used as a storage area for various short-term data.

  An imaging unit 145 is connected to the video capture I / F 140, and image data obtained by imaging by the imaging unit 145 is converted and compressed into a predetermined format (for example, JPEG format) and transferred to the primary storage device 120. Here, the imaging unit 145 includes optical components included in a general network camera such as an imaging element and a lens for capturing a moving image or a still image. A pan head 155 is connected to the control I / F 150 to acquire the state of the pan mechanism, tilt mechanism, rotation mechanism, and zoom mechanism of the pan head 155, and to control the pan head 155 according to an input instruction. An I / O device 165 is connected to the device I / F 160, and receives an external signal / interrupt and outputs an external signal.

  The network I / F 190 is a communication interface for connecting a recording device such as a DVR and outputting a captured image like a CCTV camera. In order for the camera server 100 to function as a network camera, the network I / F 190 communicates with various clients connected to the network 195 including the client 200 via a communication medium such as Ethernet (registered trademark). Do.

  The client 200 includes 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. Various components of the client 200 are connected to each other via an internal bus 280.

  The CPU 210, the primary storage device 220, and the secondary storage device 230 have the same functions as the CPU 110, the primary storage device 120, and the secondary storage device 130 of the camera server 100, respectively. The keyboard 240 and the mouse 250 function as an input device that inputs various instructions to the client 200. The display 260 is configured by a display device such as an LCD. The network I / F 290 is a communication interface for connecting to the network 195.

  Here, as shown in FIG. 2, an imaging program 300, a pan head control program 310, a panorama image creation program 320, a distribution program 330, and a preset setting program 340 are loaded on the primary storage device 120 of the camera server 100. Is done. Further, as shown in FIG. 2, panoramic image data 360, device data 370, imaging data 380, and setting data 390 are stored on the secondary storage device 130 of the camera server 100.

  Needless to say, the programs and data stored in the primary storage device 120 and the secondary storage device 130 are examples, and various programs and data necessary for processing may be stored.

  In the camera server 100, the camera platform control program 310 can receive instructions from various programs and control the camera platform 155 from the control I / F 150. Further, the pan head control program 310 can receive information (for example, PTZ position) from the pan head 155, process it by the control I / F 150, and notify the notification destination (for example, the client 200) of the contents. . The pan head control program 310 stores device data 370 including information related to the camera server 100 in the secondary storage device 130. This storage destination may be not only the secondary storage device 130 but also the primary storage device 120 or a buffer. This is because the processing by the pan head control program 310 is control processing of a general pan head driving type camera, and thus detailed description thereof is omitted.

  The imaging program 300 processes the image data obtained from the imaging unit 145 by the video capture I / F 140 and stores it as the imaging data 380 in the secondary storage device 130. The storage destination may be the primary storage device 120 as well as the secondary storage device 130. The imaging data 380 is updated as appropriate every time image data is obtained from the imaging unit 145.

  The panoramic image creation program 320 has a plurality of imaging data obtained by imaging a plurality of times while shifting the imaging range of the imaging unit 145 by the imaging program 300 with respect to all directions (driving range) that can be driven by the pan head control program 310. 380 is stored in the secondary storage device 130. Thereafter, the panorama image creation program 320 synthesizes a plurality of imaging data 380 stored in the secondary storage device 130, so that panorama image data 360 (pan function, tilt function, zoom The image data corresponding to the range that can be imaged by the function is created. The method for creating panoramic image data is not limited to this, and a generally known method can be used.

  After the setting program 390 is read and initialized, the distribution program 330 receives the panorama image data 360, the device data 370, and the updated imaging data 380 in response to a request from the program (for example, the communication program 400) of the client 200. Delivered to the network 195 via the network I / F 190. The distribution destination may be not only the network 195 but also the primary storage device 120 or the secondary storage device 130.

  The preset setting program 340 accepts instructions from various programs after the setting data 390 is read and initialized. The preset setting program 340 adds, deletes, and updates preset information that stores in advance the PTZ position, which is the imaging position, as the imaging condition specified by the imaging unit 145 in the setting data 390, or stores the preset information in the network I / O. Distribution to the network 195 via F190. The distribution destination may be not only the network 195 but also the primary storage device 120 or the secondary storage device 130.

  On the other hand, a communication program 400, a display program 410, an operation program 420, and a preset list display program 430 are loaded on the primary storage device 220 of the client 200 as shown in FIG. Further, preset candidate data 480 and distribution data 490 are stored on the secondary storage device 230 of the client 200 as shown in FIG.

  Needless to say, the programs and data stored in the primary storage device 220 and the secondary storage device 230 are examples, and various programs and data necessary for processing may be stored.

  In the client 200, the communication program 400 receives data distributed from the camera server 100 via the network 195 by the network I / F 290 and stores the data as distribution data 490 in the secondary storage device 230. The distribution data 490 includes at least one of panoramic image data 360, device data 370, and imaging data 380 distributed from the camera server 100.

  The display program 410 updates the distribution data 490 of the secondary storage device 230 so that the captured image on the viewer 31 (FIG. 3) displayed on the display 260 is captured by the captured image data 380 received from the camera server 100. Update and display. The distributed panorama image data 360 is displayed on the panorama screen control dialog 35 on the viewer 31. Here, a display example of the viewer 31 is shown in FIG. The viewer 31 includes an image display unit 32 that displays an image captured by the camera server 100 and a function dialog for various functions of the camera server 100. As function dialogs, a control dialog 33 for performing remote control of the imaging unit 145 of the camera server 100, an event display dialog 34 for displaying various events generated in the camera server 100, and panorama image data 360 created by the camera server 100 are provided. A panorama screen control dialog 35 to be displayed is included. The viewer 31 is realized by the CPU 210 executing the display program 410 stored in the primary storage device 220.

  The operation program 420 waits for an event from the viewer 31 and performs control according to the event. The various function dialogs shown in FIG. 3 are displayed, for example, when instructed by an event generated by an operation on a right click menu by an operation of the mouse 250.

  Hereinafter, an operation example of the function dialog will be described.

  For example, when the PTZ movement instruction event for the camera platform 155 is received by the operation of the keyboard 240 or the mouse 250, the control dialog 33 transmits the camera platform movement instruction to the network 195 via the network I / F 290. In response to this, the camera platform control program 310 of the camera server 100 drives the camera platform 155 in response to the received camera platform movement instruction. In addition, for example, when the control dialog 33 receives a control instruction event (for example, AF / AE / AWB) for the imaging unit 145 by operating the keyboard 240 or the mouse 250, the control dialog 33 performs a control instruction to the network 195 via the network I / F 290. Send. In response to this, the imaging program 300 of the camera server 100 controls the operation of the imaging unit 145 according to the received control instruction.

  In the event display dialog 34, for example, when an event occurrence notification from the distribution program 330 is received, the event content indicated by the event notification is displayed. In the event display dialog 34, for example, when a contact control (output) instruction is received, the contact control instruction is transmitted to the network 195 via the network I / F 290, and the I / F is received according to the instruction received by the distribution program 330. The O device 165 is controlled.

  In the panorama screen control dialog 35, a panorama image based on the panorama image data 360 is displayed. For example, when a part of the panoramic image is designated by the operation of the mouse 250, the panorama screen control dialog 35 instructs the camera server 100 connected to the network 195 via the network I / F 290 to perform a control instruction. Is transmitted to cause the camera platform control program 310 of the camera server 100 to execute drive control of the camera platform 155 according to the control instruction. In particular, in the first embodiment, in addition to this processing, control by the preset list display program 430 is performed. Details of this will be described later.

  Although an example of the function dialog processing has been described above, any processing is a processing realized by a general network camera system, and thus detailed description thereof is omitted.

  When called, the preset list display program 430 reads preset candidate data 480 and displays a preset candidate list shown in FIG. This preset candidate list is a list of preset information in which attributes such as a preset name, pan angle, tilt angle, and zoom angle of view are set.

  Next, the operation of the preset list display program 430 in the panorama screen control dialog 35 will be described.

  An example of the panorama screen control UI for operating the panorama image displayed in the panorama screen control dialog 35 is shown in FIG. 4, and the processing executed by the operation program 420 based on the panorama screen control UI is shown in FIG. I will explain.

  FIG. 5 is a flowchart showing processing executed by the operation program 420. The processing in FIG. 5 is realized by the CPU 210 executing the operation program 420.

  In step S <b> 501, the CPU 210 reads panorama image data 360 stored in the secondary storage device 230 as distribution data 490. In step S <b> 502, the CPU 210 displays a panorama image based on the read panorama image data 360 on the panorama screen control dialog 35. In step S <b> 503, the CPU 210 acquires preset information of imaging conditions of the camera server 100 (information for controlling imaging by the camera server 100 including the imaging position). Specifically, the CPU 210 inquires of the preset setting program 340 of the camera server 100 about the preset information via the network 195, and holds the returned preset information in the distribution data 490. In step S504, based on the preset information, the CPU 210 converts the preset frames corresponding to all the preset positions on the panorama image data 360 (rectangular frames corresponding to the field angle range in the panoramic image defined by the preset positions) to the panoramic image. Display above. FIG. 4 shows a state in which preset frames 401 to 406 or more preset frames are superimposed and displayed on the panorama screen control UI.

  The panorama image displayed in the panorama screen control dialog 35 has attributes such as the pan angle, tilt angle, and zoom angle of view at that time, and coordinate information that defines the position of the panorama image (for example, the upper left corner of the panorama image). A plane coordinate is defined with the longitudinal direction having the corner as the origin as the X axis and the lateral direction as the Y axis. Therefore, an image area corresponding to the preset position (pan angle / tilt angle / zoom angle of view) indicated by the preset information is defined on the panorama image, and a frame surrounding the image area is displayed as a preset frame.

  In S510, the CPU 210 waits for an event. Various processes are executed according to the event that has occurred.

  In S520, the CPU 210 determines whether or not an event for clicking a panoramic image displayed on the panorama screen control dialog 35 using the mouse 250 has occurred as an event. The click position on the panoramic image is a focus position that is being watched by the operator. When an event for clicking a panoramic image occurs (YES in S520), the CPU 210 includes a coordinate point indicating the clicked position from preset information held in the distribution data 490 in S521. A preset (group) is selected and stored in the preset candidate data 480. The preset (group) to be selected is an imaging condition that is a selection candidate among a plurality of preset imaging conditions. In S521, an imaging condition that is a selection candidate is specified.

  For example, in FIG. 4, it is assumed that preset frames 401 to 406 corresponding to the preset information of the preset names 1 to 6 are displayed. In this state, when the mouse 250 is clicked at the position of the mouse cursor 251, the pan position and the tilt position on the panorama image data 360 at the position specified by the click are calculated to calculate coordinates. In this case, the calculated coordinates are included in the angle of view range of the preset frame 401 and the preset frame 403, but are not included in the angle of view range of the preset frame 402. Therefore, the preset frames 401, 402, and 403 overlap. In addition, only the preset frame 401 and the preset frame 403 are selected as preset candidates, and these are stored in the preset candidate data 480. That is, in this case, the preset information of the preset names 1 and 3 is held in the preset candidate data 480. Naturally, the preset frames 404 to 406 are not selected as preset candidates.

  Thereafter, in S580, the CPU 210 calls the preset list display program 430, and displays the preset list 61 by the preset list display program 430 as shown in 6A of FIG. More specifically, the preset list display program 430 reads the preset candidate data 480 and displays a preset list 61 that is a list of preset information including a preset name, a pan value, a tilt value, and a zoom value. In the state of FIG. 4, since the preset information of the preset names 1 and 3 is held as the preset candidate data 480, the preset list 61 including the entries corresponding to the preset frame 401 and the preset frame 403 is displayed in 6A of FIG. It becomes like this. In this way, the preset list display program 430 presents the preset list 61 that is visual information for selecting a desired imaging condition from imaging conditions that are selection candidates. In the preset list 61, imaging conditions that are selection candidates are presented so as to be distinguishable from imaging conditions that are non-selection candidates.

  Thereafter, the process returns to S510.

  If an event for clicking the panoramic image has not occurred (NO in S520), in S530, the CPU 210 determines whether an event for dragging the panoramic image displayed on the panorama screen control dialog 35 using the mouse 250 has occurred as an event. Determine whether. When an event for dragging the panoramic image occurs (YES in S530), in S531, the CPU 210 selects a preset (group) included in the dragged rectangle from the preset information held in the distribution data 490. , And stored in the preset candidate data 480. The range dragged on the panoramic image is the attention position that the operator is paying attention to. The selected preset (group) is an imaging condition that is a selection candidate among a plurality of preset imaging conditions. In S531, an imaging condition that is a selection candidate is specified.

  For example, in FIG. 4, even if it is difficult to select the preset frames 404, 405, and 406 as small rectangles, the locus drawn by the drag operation of the mouse 250 (the drag start position by pressing the mouse button and the drag end by releasing the mouse button) Coordinates are calculated by calculating a pan range and a tilt range of a rectangular area (coordinate range) on the panoramic image data 360 defined by a line segment (diagonal line) connecting two positions of the positions. For example, the angle of view of the preset frame 404 and the preset frame 405 is included in the pan / tilt range specified by dragging, and the angle of view of the preset frame 406 is not included in the pan / tilt range specified by dragging. In this case, only the preset frame 404 and the preset frame 405 are held in the preset candidate data 480.

  Thereafter, in S580, the CPU 210 calls the preset list display program 430, and displays the preset list 61 including the entries corresponding to the preset frame 404 and the preset frame 405 as shown in 6B of FIG. 6 by the preset list display program 430. To do. That is, a preset list 61 including preset information of preset names 4 and 5 is displayed. Thereafter, the process returns to S510. In this way, the preset list display program 430 presents the preset list 61 that is visual information for selecting a desired imaging condition from imaging conditions that are selection candidates. In the preset list 61, imaging conditions that are selection candidates are presented so as to be distinguishable from imaging conditions that are non-selection candidates.

  When an event for dragging the panoramic image has not occurred (NO in S530), in S550, the CPU 210 selects one of the preset groups as preset candidates in the preset list (eg, preset list 61) by the mouse 250 as an event. It is determined whether an event to be clicked has occurred. Here, the entry of each preset information displayed in the preset list 61 can be selected by clicking the mouse 250. Then, preset information corresponding to the entry selected by the click is transmitted as a control instruction (PTZ control instruction) of the camera server 100.

  When an event for clicking the preset list occurs (YES in S550), in S551, the CPU 210 selects a preset (for example, preset 1) at the clicked position on the preset list. At this time, in order to distinguish between the preset selected on the preset list and the other unselected presets, at least one of the display forms (for example, the selected preset is highlighted and the unselected preset is selected). May be displayed in gray out).

  In step S552, the CPU 210 requests the pan / tilt control program 310 of the camera server 100 via the network 195 to control the imaging position (PTZ position) indicated by the selected preset (for example, preset 1), and then displays the preset list display. clear. Thereby, the camera platform 155 is controlled by the camera platform control program 310 to the imaging position indicated by the selected preset. Thereafter, the process returns to S510.

  If an event for clicking the preset list has not occurred (NO in S550), in S590, the CPU 210 determines whether an end event has occurred. If no end event has occurred (NO in S590), the process returns to S510. On the other hand, when the end event has occurred (YES in S590), the CPU 210 ends the process.

  An event for the viewer 31 is also processed by the operation program 420. In addition, by clicking on an irrelevant position on the panorama screen control dialog 35, an event in a general UI such as releasing the selected state is also processed, but it will not be described further here. Also, the end event occurs, for example, when a button or menu (not shown) for ending the display of the panorama screen control dialog 35 or the viewer 31 is operated.

  In the first embodiment, the preset candidate data 480 is stored in the client 200. However, the present invention is not limited to this. For example, the preset candidate data 480 may be calculated and held on the camera server 100 side by making an inquiry to the camera server 100. In that case, the first embodiment can be realized by the camera server 100 alone by receiving an instruction from the client 200 via the network 195.

  As described above, according to the first embodiment, a plurality of preset frames corresponding to a plurality of preset positions that are set are displayed, and a preset that is finally designated according to an operation on the plurality of preset frames. A list of preset candidates (preset list) that are candidates for the above is generated. That is, the presets that are more likely to be selected from all the preset presets are narrowed down and displayed as a preset list. Thereby, the user can select a desired preset from the preset list more efficiently and easily.

<Embodiment 2>
In the first embodiment, the specific preset is selected from the attributes of the preset list (preset name, pan, tilt, zoom). However, the present invention is not limited to this.

  In the second embodiment, a configuration in which the preset candidate state is clearly indicated by changing the display attribute of the preset frame corresponding to the preset group selected in S521 or S531 in FIG. 5 will be described.

  The system configuration of the second embodiment is the same as that of FIG. 1 of the first embodiment.

  In the second embodiment, in particular, the processing contents of the operation program 420 and the preset list display program 430 stored in the primary storage device 220 of the client 200 among the programs realizing the second embodiment are different from those in the first embodiment.

  In the second embodiment, when called, the preset list display program 430 reads the preset candidate data 480 and changes and displays the display attributes of the preset candidate preset frames as shown in 6C and 6D of FIG. This includes, for example, changing the display form, such as changing the dotted line, blinking, or color.

  For example, when preset frames 401 and 403 are selected as preset candidates among the preset frames 401 to 403 in FIG. 4, the preset frame 402 remains a solid line in FIG. 6C, but the preset frames 401 and 403 are preset candidates. Is displayed with a broken line to indicate that it is in a selected state.

  For example, when the preset frames 404 and 405 are selected from the preset frames 404 to 406 in FIG. 4, the preset frame 406 remains a solid line, but the preset frames 404 and 405 are selected as preset candidates. In order to show this, it is displayed in a striped pattern (shaded).

  The processing in the second embodiment is similar to the processing in FIG. 5 except that the preset list display program 430 changes the display mode of the preset frame as shown by 6C and 6D in FIG. The display forms in 6C and 6D in FIG. 6 are merely examples, and it is needless to say that other display forms (blink display, color display) can be used as long as they can be identified as whether or not they are selected as preset candidates. .

  As described above, according to the second embodiment, in addition to the effects described in the first embodiment, with respect to a preset frame that is a preset candidate, the display form of the preset frame itself is changed to the display form of a preset frame that is not a preset candidate. Is displayed in an identifiable manner, so that preset candidates can be presented to the user more intuitively.

<Embodiment 3>
In the second embodiment, a specific preset is selected from a preset frame that is a preset candidate. However, the present invention is not limited to this.

  In the third embodiment, the preset list of the preset group selected in S521 or S531 in FIG. 5 is displayed, and the preset list display attribute (first display attribute) corresponding to the preset group is changed. A configuration for clarifying the selection state by displaying the preset frame corresponding to the preset selected from the above with the second display attribute different from the first display attribute will be described.

  The system configuration of the third embodiment is the same as that of FIG. 1 of the first embodiment.

  In the third embodiment, in particular, the processing contents by the operation program 420 and the preset list display program 430 stored in the primary storage device 220 of the client 200 among the programs realizing the third embodiment are different from those in the first embodiment.

  In the third embodiment, when the preset list display program 430 is called, the preset candidate data 480 is read. First, like the preset list display program 430 of the second embodiment, preset candidates are displayed as in 6C and 6D of FIG. Change the display attribute of the preset frame and display it. In the third embodiment, for example, a diagonal line is used.

  Next, the preset list display program 430 reads the preset candidate data 480 and displays the preset list 61 such as 6A and 6B in FIG. 6, similarly to the preset list display program 430 of the first embodiment.

  Here, when the preset information (preset frame 403) of preset name 3 is selected on the preset list 61, the display attribute of the preset frame 403 on the panorama screen control UI is changed. In the third embodiment, for example, the conventional broken line pattern is further changed to a thick broken line pattern.

  Here, when the confirm button 701 in FIG. 7 is pressed, the selection of the preset frame 403 is confirmed, and the control of the imaging unit 145 of the camera server 100 is performed based on the preset information of the preset frame 403 whose selection is confirmed. Will be done. Here, the confirmation button 701 is not indispensable. For example, the confirmation is performed by performing a confirmation operation such as double-clicking on the preset frame 403 or the entry (preset 3) corresponding to the preset frame 403 on the preset list 61. May be.

  As described above, according to the third embodiment, in addition to the effects described in the first and second embodiments, a preset frame selected from a plurality of preset frames corresponding to preset candidates is further compared with other preset frames. By highlighting, it is possible to more easily grasp the selection state of the intended preset.

<Embodiment 4>
In the first to third embodiments, as the imaging condition, in particular, a preset position (pan angle / tilt angle / zoom angle of view) which is one of the preset information is controlled. However, in order to control imaging of the camera server 100. It goes without saying that this information can be appropriately included in the preset information. For example, when the imaging time zone is at night, a sensitivity value that is higher than that during daytime may be included in the preset information together with the preset position.

  As described above, according to the present invention, preset information including at least an imaging position is stored in advance as an imaging condition, and preset information that is a selection candidate is displayed on the captured image according to the designation of the position of interest on the captured image. It is characterized in that the preset information of other non-selected candidates is presented so as to be distinguishable.

  Here, the focus position is, for example, an arbitrary position specified by a click operation on the captured image, or two positions specified by a drag operation on the captured image (drag start position and drag end position). It includes an arbitrary position range defined by.

  For example, in the first embodiment, the preset list 61 is displayed on the panorama screen control UI as a method for presenting preset information as selection candidates so as to be distinguishable from preset information of other non-selection candidates on a captured image. In the second embodiment, this corresponds to changing the display form (display attribute) of the preset frame, such as the broken line display and the shaded display. In this way, visual information for selecting preset information as selection candidates is presented on the panorama screen control UI. However, the preset list 61 is not necessarily presented on the panorama screen control UI, and may be presented at a position different from the panorama screen control UI in the same screen using a dedicated dialog.

  In addition, the function of the above embodiment is realizable also with the following structures. That is, it is also achieved by supplying a program code for performing the processing of the present embodiment to a system or apparatus, and a computer (or CPU or MPU) of the system or apparatus executing the program code. In this case, the program code itself read from the storage medium realizes the function of the above-described embodiment, and the storage medium storing the program code also realizes the function of the present embodiment.

  Further, the program code for realizing the function of the present embodiment may be executed by one computer (CPU, MPU), or may be executed by a plurality of computers cooperating. Also good. Further, the program code may be executed by a computer, or hardware such as a circuit for realizing the function of the program code may be provided. Alternatively, a part of the program code may be realized by hardware and the remaining part may be executed by a computer.
