<p><P>PROBLEM TO BE SOLVED: To provide an image decoding apparatus capable of decoding a run_before syntax with the reduced number of cycles. <P>SOLUTION: An image decoding apparatus comprises: an update and output section 101 which inputs a bit stream and outputs the bit stream after updating a syntax in the head of the bit stream in accordance with the code length thereof; a decode section 102 which decodes the variable length code of the syntax from the bit stream update and output section 101 in response to a decode request; a zeros Left update section 103 which updates zeros Left with the decoded specific syntax; a run_before remaining update section 104 which updates the number of remaining run_before with the decoded specific syntax; and a syntax selection section 105 which selects the syntax to be decoded, wherein the run_before syntax of a plurality of zeros, and the run_before syntax of one non-zero, or the run_before syntax of a plurality of zeros are decoded at once. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
