<p><P>PROBLEM TO BE SOLVED: To improve an encoding efficiency of a variable length encoding when an image is divided into different-sized blocks and encoded. <P>SOLUTION: The number of coefficients of a periphery block is referred and a variable length encoding table is switched at a code row forming portion 104 when the number of the coefficients of an encoding objected block is encoded. When the sizes of the encoding objected block and the periphery block are different, the number of the coefficients of the periphery block is converted so as to accord the size of the encoded objected block to the size of the periphery block. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
