发明名称 Motion detecting circuit utilizing inter-frame difference signals of successive fields
摘要 A motion detecting circuit suitable for detecting object-movement on an interlaced TV signal includes at least three field memories, subtracters, absolute circuits and an adder circuit. The motion detector evaluates object-movement by accumulating frame difference signals between adjacent fields.
