ABSTRACT:
Variable-length encoder16feeds a CBP as an input symbol H1to variable-length code output part30. Coded symbol memory31supplies CBPs in neighboring blocks as coding map table reference information H2to coding map table provider32. Coding map table provider32determines a coding map table used in coding of the CBP, based on these CBPs in the neighboring blocks, and provides a coding map table H4to variable-length code output part30. Variable-length coding table provider33feeds a variable-length coding table H5to variable-length code output part30. Then the coding target CBP is subjected to variable-length coding, and the resultant is outputted as coded data D9. This allows information source coding of coding symbols to be performed efficiently according to the coding condition and the property of image.
