Abstract: To provide an image decoding apparatus that suppresses overhead of parallel processing to improve parallelization efficiency and reduce circuit costs, while solving neighboring macroblock dependencies. The image decoding apparatus (100) includes first and second decoding circuits (101, 102) having a transfer unit that transfers right neighborhood information or left neighborhood information, and first and second transfer completion detection units (104, 105) that respectively detect whether or not the left neighborhood information or the right neighborhood information has been transferred to the first and second decoding circuits (101, 102). Each of the first and second decoding circuits (101, 102) decodes a decoding target macroblock positioned at an edge of a region, when the transfer of the left neighborhood information or the right neighborhood information is detected. A boundary line between regions is orthogonal to a decoding direction corresponding to an order in which macroblocks adjacent to each other are sequentially decoded.

Abstract: A motion estimation device executes motion estimation for a macroblock in a current picture, using pixel data of a reference picture in a multi-frame memory (504), including the following elements. A local memory (702) holds a part of the pixel data. The part is in a first range from which motion is estimated in first motion estimation, and read out from the multi-frame memory (504). A common motion estimation unit (704) executes the first motion estimation using pixel data in the part held in the local memory (702). A direct motion estimation unit (108) executes the second motion estimation using pixel data in the pixel data of the reference picture by an algorithm different from that of the first motion estimation. The pixel data used by the direct motion estimation unit (108) is included in a second range which includes the first range and is larger than the first range.
