SYSTEM AND DEVICE FOR MOTION DETECTION OF PREDICTION BETWEEN MOTION COMPENSATION FRAMES

摘要

PURPOSE: To shorten an arithmetic time and to improve the precision of motion prediction. CONSTITUTION: Image data is inputted 1 and inputted to a motion detector 2. The movement detector 2 performs motion detection on the basis of the inputted image data and data in a previous image memory 3. For the motion detection by the motion detector 2, a vector set stored in a ROM 5 is used and operation for finding a maximum point of similarity by matching on the basis of the vectors is repeated to find a motion vector. The point calculated by the motion detector 2 is stored in a RAM 6 and an image output 4 and a vector data output 7 are performed. Consequently, the operation quantity is reduced and the processing time of the motion detection can be shortened.
