Abstract
An image signal which is output by a video camera is segregated into image data S2 and synchronous data S3 by the synchronizing segregation circuit 1. At each frame, image data S2 is sequentially stored in the image data multilayer memory 8 which consists of frame memories formed in a ring shape. When an anomalous phenomena which includes this image data S2 is detected by the anomalous phenomena detecting device 2, then for image data S2 and anomalous image data S4, from a time immediately before the occurrence of an anomalous phenomena until the elapse of a prespecified period of time, maintenance and storage in the multilayer memory 8 for image data and in the multilayer memory 7 for extracted anomalous image data by the start/stop control circuit 6. Following this, the image data S2 and the anomalous image data S4 from immediately before the occurrence of an anomalous phenomena until the elapse of a prespecified period of time is forwarded to storage device 10 by the data transfer circuit 9. Based on the thus obtained images from before and after the occurrence of an anomalous phenomena, analysis and resolution of an anomalous phenomena occurring within a surveilled area may be carried out.
