ABSTRACT:
A movement detection apparatus comprises a first circuit for detecting a difference signal between first and second image signals, a second circuit for integrating the difference signal detected by the first circuit, a third circuit for detecting respective image signal levels of the first and second image signals when the image signals reach a predetermined level, a fourth circuit for detecting a difference signal of plural detection results given by the third circuit, and a fifth circuit for dividing the second circuit output signal by the fourth circuit output signal to detect a signal corresponding to image movement.
