COMPRESSION/EXPANSION DEVICE FOR MOVING PICTURE VIDEO SIGNAL

摘要

PURPOSE:To compress/expand a moving picture by reducing in comparatively small size as well as displaying it in comparatively large size. CONSTITUTION:The moving picture is displayed on a color monitor 44 based on a digital video signal DRGB1 obtained by a first A/D con/N verter 52, and the moving picture is captured in small size by reducing and compressing a video signal DRGB2 obtained with a second A/D converter 54. When the moving picture is reproduced, a video expansion part 66 expands and magnifies a compression video signal, and displays a magnified moving picture on the color monitor 44.
