Gerät und Verfahren zur Bewegungsfeststellung

摘要

A motion detection apparatus for detecting motion of an inputted image includes a reference image memory (14) for storing the image as a reference image to be used for detection of motion, updating means (13) for periodically updating the reference image stored in the reference image memory (14), and a current image memory (12) for storing an image inputted at the present time as a current image. Motion detection means (18-23) compares the current image stored in the current image memory (12) with the reference image stored in the reference image memory (14) and detects motion of the image based on the result of the comparison. A dead zone processing section (24) extends the interval within which motion of the image is detected by the motion detection means (18-23) by a predetermined extension time.
