Abstract: An image, which is captured by a camera that a worker, etc., carries, is once stored in a ring buffer memory for storing image signals. The image is extracted from the ring buffer memory, and a quasi-moving image is generated. In a normal state, the quasi-moving image is displayed on a monitor of a center such as a control room, etc. via codecs on transmitting and receiving sides. When a user viewing the monitor makes a request to view a sharp image of a particular frame, or the high-quality motion of a subject while viewing the frames preceding or succeeding a particular frame, the image frame or frames are read from the buffer memory for storing image signals, and displayed on the monitor.

Abstract: The invention relates to a video broadcasting equipment for downloading image information given from a camera to an image processing equipment, the image processing equipment which accomplishes centralized supervisory of image information, and the camera. The video broadcasting equipment discriminates a dynamic region of image information individually representing an image of a coverage of a camera and transmits the image information and a discrimination result of the dynamic region to the image processing equipment through a communication path. In the centralized supervisory system to which the present invention is applied, traffic on a communication path formed to the cameras does not increase, and image information to be subjected to dynamic image processing is specified according to a result of processing of discriminating the dynamic region. The discrimination processing is generally simple and its throughput is substantially small in comparison with the dynamic image processing.
