Abstract

The movement detector should reliably detect the movement of a picture element at low signal processing speed. The values of picture elements vertically above one another in a corresponding number of parallel detectors are used for detecting movement and the value determined for one picture element is weighted with those of the picture elements adjacent in time. <IMAGE>
