Disclosed is a motion detecting circuit for detecting the motion of an object in an interlaced television signal, in which at least three field memories (58, 59, 60) are connected in cascade, and an inter-field difference signal and an inter-frame difference signal are detected from input and output signals of these field memories (58, 59, 60), whereby a signal indicating the existence of movement of the object is produced when movement is detected in the inter-field difference signal or the inter-frame difference signal. |
