Application No. 08/627,010
BACKGROUND
The invention is directed to a method and apparatus for compressing a motion
picture. Representative claim 1 is reproduced below.
1. A picture compression apparatus comprising:
means for compression input picture data for a first frame;
basic compression ratio setting means for setting the basic compression
ratio in compressing the input picture data for said first frame by said compression
means;
means for designating an area in the first frame input picture;
designated area importance setting means for setting the importance in
compressing the input picture data for said first frame corresponding to the area
designated by said designation means;
compression ratio modifying means for modifying the basic compression
ratio based upon the importance for said designated area as set by said
designated area importance setting means; and
automatic follow-up means for automatically following an object in a second
frame which is positioned within said designated area of said first frame thereby
applying said modified compression ratio to said object, even if said object is
positioned differently in said frame.
