Embodiment approach 1

[0024] First, refer to figure 1 , the monitoring system 100 according to the embodiment of the present invention will be described. figure 1 It is a block diagram of the monitoring system 100 concerning Embodiment 1.

[0025] Such as figure 1 As shown, the monitoring system 100 includes a first camera 1 and a control device 5 . The first camera 1 is an example of a first photographing device.

[0026] The first camera 1 includes an imaging element 11 , a camera communication unit 12 , a camera storage unit 13 , and a camera control unit 14 . The camera control unit 14 is an example of a control unit.

[0027] The imaging element 11 performs imaging of the imaging area. The imaging element 11 generates data representing a captured image, and sends the data to the camera control unit 14 . Hereinafter, data representing a captured image is described as "captured image data". The imaging element 11 is, for example, a CCD (Charge Coupled Device) image sensor or a CMOS (Compl...

Embodiment approach 2

[0085] Next, refer to Figure 11 to Figure 15 , the monitoring system 100 according to Embodiment 2 will be described. In the second embodiment, there are several cameras, which is different from the first embodiment. In addition, the pre-event detection processing is also different from the first embodiment. Hereinafter, matters in Embodiment 2 that are different from Embodiment 1 will be described, and descriptions of parts that overlap with Embodiment 1 will be omitted.

[0086] First, refer to Figure 11 , the configuration of the monitoring system 100 according to Embodiment 2 will be described.

[0087] Figure 11 It is a block diagram of the monitoring system 100 concerning Embodiment 2. Such as Figure 11 As shown, the monitoring system 100 also has a second camera 2 . The second camera 2 and the first camera 1 shoot different shooting areas. Hereinafter, the imaging area of ​​the first camera 1 is described as "first imaging area", and the imaging area of ​​th...

Abstract

The invention provides a monitoring system. The monitoring system includes an imaging device, a control unit, a storage unit, and a notification unit. The photographing device photographs the photographed area, and generates photographed image data representing the photographed image. The control unit detects an event based on the captured image data. An event includes a pre-event and a post-event, and the post-event is detected after the pre-event ends. When the control unit detects the preceding event, it changes the first flag from the dormant state to the active state, and maintains the first flag in the active state even after the preceding event ends. When the control unit detects the post-event, it changes the second flag from the dormant state to the active state, so that the notification unit performs notification of continuous event occurrence information, and the continuous event occurrence information indicates that the continuous event has occurred.

Description

technical field [0001] The invention relates to a monitoring system. Background technique [0002] There is a surveillance camera system with a network camera and a display device. A network camera includes a shooting unit, a control unit and a communication unit. The photographing unit includes an image acquisition unit and a video transmission control unit. The image obtaining unit obtains a captured image captured by the imaging element. The video transmission control unit encodes the captured image to obtain a video, and sends the video to the display device. The control unit includes an object detection processing unit, an event detection processing unit, and an event transmission control unit. The object detection processing unit detects an object such as a human body. The event detection processing unit detects the occurrence of an event such as “removal” or “prank (interference with shooting)” based on the state of the object detected by the object detection pro...
