<p>From a memory, a stored search field is inputted to a simple movement detecting circuit. From the simple movement detecting circuit, the amount of movement is outputted and inputted to a control judging circuit. A movement detecting circuit receives the current frame and a search frame and finds a final moving vector practically used for movement compensation. From the control judging circuit, setting parameters for setting up a search range are sent to the movement detection circuit according to a predicted amount of movement predicted using a simple moving vector, and thereby a search range is set up. Thus, the problem that the conventional full-search block matching method requires a very large scale of circuit when an image in which movement is very quick as in a sport program is handled is solved.</p> |
