It is displayed on the entire screen 107.

  FIG. 7 is a flowchart showing display frequency setting processing for a specific monitoring area. In this flowchart, steps S421 to S430 are executed by the CPU 201 of the monitoring terminal 200, and steps S441 to S448 are executed by the CPU 101 of the image storage server 100.

  In FIG. 7, first, a screen for requesting screen information for displaying the planar layout screen 40 by pressing the “layout display” button on the monitoring screen 600 (FIG. 6) displayed on the monitor 107 of the monitoring terminal 200. A request signal is transmitted to the image storage server 100 (step S421). When receiving the screen request signal (step S441), the image storage server 100 transmits the screen information of the planar layout screen 40 to the monitoring terminal 200 (step S442), and then waits for reception of operation information (step S443). The monitoring terminal 200 receives the screen information transmitted from the image storage server 100 in step S442, and displays the planar layout screen 40 (FIG. 4) on the monitor 107 based on the screen information (step S422).

  Next, in the monitoring terminal 200, after selecting a frame corresponding to a specific monitoring area (hereinafter simply referred to as “specific location”) on the planar layout screen 40 (step S <b> 423), “setting change” on the planar layout screen 40 is selected. It is determined whether or not the "" button has been pressed (step S424). When the “setting change” button is not pressed, the process returns to step S422, and when the “setting change” button is pressed, a screen request signal is transmitted to the image storage server 100 (step S425). In the image storage server 100, when the screen request signal is received (step S444), the screen information of the display frequency setting screen (FIG. 5) of the specific location is transmitted to the monitoring terminal 200 in accordance with the screen request signal transmitted from the monitoring terminal 200. (Step S445), and then waits for reception of setting information (Step S446). The monitoring terminal 200 receives the image information transmitted from the image storage server 100 in step S445, and displays the display frequency setting screen 500 of FIG. 5 on the monitor 207 based on the screen information (step S426).

  Thereafter, the monitoring terminal 200 selects a display frequency and a required item (trigger event) at a specific location on the display frequency setting screen 500 (step S427). Next, it is determined whether or not an essential item has been selected (step S428). If the essential item has not been selected, the process returns to step S426. If the essential item has been selected, the display selected in step S427. The frequency setting information is transmitted to the image storage server 100 (step S429). When the image storage server 100 receives the display frequency setting information (step S447), the display frequency setting information transmitted from the monitoring terminal 200 is stored in the hard disk 108 (step S448), and the process returns to step S443.

  The monitoring terminal 200 determines whether or not the “end” button on the planar layout screen 40 has been pressed (step S430). If the “end” button has not been pressed, the process returns to step S426, and the “end” button has been pressed. If so, this process ends.

  FIG. 8 is a flowchart showing display switching control processing for switching display of images on the monitoring screen 600 of FIG. In this flowchart, steps S540 to S555 are executed by the CPU 201 of the monitoring terminal 200, and steps S521 to S531 are executed by the CPU 101 of the image storage server 100.

  In FIG. 8, first, the image storage server 200 receives the image data transmitted from the monitoring cameras 10A to 10N and the event information based on the trigger event transmitted from the sensor units 10a to 10 (step S521), and the received image. Data and event information are stored in the hard disk 108 (step S522). Further, the control information I of the normal image switching timing stored in the hard disk 108 is transmitted to the monitoring terminal 200 at a predetermined timing (step S523).

  In the monitoring terminal 200, after receiving the image data transmitted from the monitoring cameras 10A to 10N (step S540), it is determined whether or not the control information I transmitted from the image storage server 200 has been received (step S541). When the control information I is received, the image captured in the RAM 202 is changed based on the control information I (step S542), the normal image is switched and displayed on the monitor 107 (step S543), and the control information I is received. If not, the process proceeds to step S543 as it is. When the “layout display” button on the monitoring terminal display screen 600 is pressed in step S543, the flat layout screen 40 of FIG. 4 is popped up.

  The image storage server 100 refers to past event information stored in the hard disk 108 to determine whether the event information transmitted from the sensor unit is a new event (step S525). In S527, if the event is a new event, control information II for displaying an image of the monitoring camera connected to the sensor unit that transmitted the event information is transmitted to the monitoring terminal 200 (Step S526), and the process proceeds to Step S527. .

  When the monitoring terminal 200 receives the control information II (step S544), the image captured in the RAM 202 is changed based on the control information II (step S545), and the monitoring camera installed at the event occurrence location (specific monitoring area) Is displayed larger than the normal image (step S546). Thereby, the image displayed on the monitoring terminal display screen 600 is switched. When the “layout display” button is pressed in step S546, the plane layout screen 40 of FIG. 4 is popped up.

  Next, the image storage server 100 refers to the past event information stored in the hard disk 108 and continues the event information transmitted from the sensor unit installed at the event occurrence location (for example, the second barn No. 5). If the event information is not continuously received, the process proceeds to step S529. If the event information is not continuously received, the event occurrence location is determined. Control information III for ending the image display of the monitoring camera being photographed is transmitted to the monitoring terminal 200 (step S528), and the process proceeds to step S529.

  The monitoring terminal 200 determines whether or not the control information III has been received (step S547). If the control information III has not been received, the process proceeds to step S550. If the control information III has been received, the event information further It is determined whether or not a predetermined time has elapsed after the end of reception (step S548). If the predetermined time has not elapsed, the process proceeds to step S550, and if the predetermined time has elapsed, the display of the image at the event occurrence point is terminated. (Step S549), the process proceeds to step S550.

  Next, the monitoring terminal 200 determines whether or not a single frame (single frame 425) corresponding to the event occurrence location is selected by double-clicking on the layout screen of FIG. 4 (step S550). When the single frame corresponding to the event occurrence location is not selected, the process proceeds to step S555. When the single frame corresponding to the event occurrence location is selected, the number of times referring to the event occurrence location image is increased by one. The reference history of the event occurrence location image is updated (step S551), and a change request signal for requesting a change in control information for controlling the display of the event occurrence location image is transmitted to the image storage server 100 (step S552).

  When the image storage server 100 receives the change request signal (step S529), it reads out the imaging control values (pan / tilt / zoom values) necessary to image the event occurrence location from the hard disk 108, and images the event occurrence location. The imaging control value is transmitted to the monitoring camera that is being operated (step S530). Thereafter, the imaging control value of the monitoring camera at the event occurrence location is changed (step S531), and the process returns to step S526.

  On the other hand, in the monitoring terminal 200, the captured image in the RAM 202 is changed to the image of the event occurrence location selected in step S550 (step S553), and the image of the event occurrence location is displayed as a normal image on the monitoring screen 600 of FIG. A larger image is displayed (step S554). If the “layout display” button is pressed in step S554, the plane layout screen 40 of FIG. 4 is displayed in a pop-up manner. Thereafter, it is determined whether or not the “end” button on the monitoring terminal display screen 600 has been pressed. When the “end” button has not been pressed, the process returns to step S540, and when the “end” button has been pressed, this processing is performed. Exit.

  According to the present embodiment, in the image storage server 100, event information transmitted from the sensor units 10a to 10n is stored (step S522), and the control information I for controlling the display of the image of the monitoring area in the monitoring terminal 200 is stored. The control information II of the image at the event occurrence location is transmitted based on the event information (step S526), and the control information (imaging control value) of the image at the event occurrence location is received in response to the change request signal from the monitoring terminal 200. On the other hand, in the monitoring terminal 200, the images of the plurality of monitoring areas are switched and displayed based on the control information I transmitted from the image storage server 100 (step S543), and the plurality of monitoring areas are arranged. A plane layout screen 40 composed of a plurality of single frames arranged so as to correspond to each other and selectable on the screen is provided. Made is, change request signal for changing the control information of an event occurrence location of an image corresponding to a single frame selected on the planar layout screen 40 is transmitted to the image storage server 100 (step S552). That is, based on the control information transmitted from the image storage server 100, images of a plurality of monitoring areas are switched and displayed on the monitoring screen 600, and the administrator can select a single frame corresponding to the event occurrence location on the planar layout screen 40. By selecting, the imaging control value of the monitoring camera at the event occurrence location is changed. Thereby, even when there are a plurality of monitoring areas, it is possible to easily recognize the event occurrence location and realize fine monitoring by changing the imaging control value of the monitoring camera installed at the event occurrence location. Thus, the burden on the administrator can be reduced and even a small number of administrators can appropriately cope with an unexpected situation.
