<p><P>PROBLEM TO BE SOLVED: To suppress an increase in predictive residue resulting from a shadow region in a video image to improve encoding efficiency. <P>SOLUTION: The video image encoding device encodes a video image composed of a series of input images IN1. The device comprises a detector 10a for detecting a foreground region, a background image, and a shadow region projected at the background image by the foreground region in the input image; a shadow information compressor 2a for executing compression processing to compress the amount of the information of the shadow region; and an encoder 4a for encoding information on the foreground region, the background image, and the compression processed shadow region. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
