Abstract
An area to be monitored is picked up by a TV camera, and data of the picked-up image is converted into digital data in units of frames and stored in frame memories. The image data stored in the frame memories are read out, and a change region is extracted as an image of a moving object. The extracted moving object image has a plurality of dispersed regions including a shadow image. Only the dispersed regions corresponding to the moving object are extracted by setting a frame, and a noise image including the shadow image is removed.
