Patent number: 7228064Abstract: The present invention provides an image decoding apparatus that realizes speed-up processing of taking out an MR (macroblock remainder) from a fixed length unit that consists of a first DCT block and the MR, without increasing cost. A Setup processor 3 outputs one out of a plurality of fixed length units that constitute an SB (synchronized block). First, calculation is performed for a length from a beginning of the fixed length unit to a EOB (end of block) that is included in the fixed length unit. The calculated length is then used as an offset in taking out the MR. Then an end portion of a second DCT block that is included in the MR is combined with a corresponding beginning portion of the second DCT block, in order to obtain the complete second DCT block. The complete second DCT block is outputted to a variable length code decoder 13.Type: GrantFiled: August 2, 2002Date of Patent: June 5, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshiyuki Wada, Makoto Hirai, Tokuzo Kiyohara, Kosuke Yoshioka, Hideshi Nishida, Yukiharu Ieda
