<p><P>PROBLEM TO BE SOLVED: To further improve the compression efficiency of image data. <P>SOLUTION: The image data is divided into at least one brightness plane for indicating the brightness and at least one color-difference plane for indicating the color difference (step S2). Thereafter, the variation in brightness existing in the brightness plane is eliminated (step S3), and then the image data is coded after eliminating the variation in brightness (step S7). <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
