ABSTRACT:
A motion detection system for detecting motion in input images. One of the input images is stored for use as a reference image for motion detection processing. The reference image is updated according to any one of a multiple of possible updating modes. Images input after establishment of the reference image are compared to the reference image and the detection of motion in the input images is based on the comparison. The interval in which motion in the input images is detected is extended according to a predetermined extension time.
