Laufbildkompressionsschaltung und Laufbildkompressionsverfahren unter Verwendung von Bewegungsvektoren

摘要

A motion picture compression circuit includes a first frame memory 20 for storing the start frame of motion picture information constructing a picture; second and third frame memories 10 for storing two successive frames of the motion picture information; a picture boundary detector 30 for detecting a picture boundary from the motion picture information of the two successive frames supplied from the second and third frame memories 10; a motion vector detector 40 for predicting a motion vector from the motion picture information of the start frame and end frame; a controller 50 for generating data required for forming a picture, according to the detected picture boundary and motion vector; and a picture reproducer 60 for reproducing an omitted frame using the data generated by the controller, and inserting it between the start frame and end frame.
