摘要： When compression encoding processing of an image is performed in units of macroblocks using pipeline structure, application of the skip mode or the like according to MPEG4AVC to compression encode an encoding target block requires motion vectors and the like of adjacent blocks of the encoding target block. However, depending on the structure of the pipeline stages, the motion vectors and the like may not be determined. In such cases, the skip mode cannot be applied to compression encode the encoding target block. The present invention aims to solve this problem and (i) calculates all motion information candidates, of the encoding target block, corresponding to all motion information selectable by a previous block of the encoding target block, and (ii) selects, as the motion information of the encoding target block in the skip mode, the motion information corresponding to the motion information determined for the previous block.
摘要翻译：当使用流水线结构以宏块为单位执行图像的压缩编码处理时，根据MPEG4AVC的跳过模式等的应用对编码对象块进行压缩编码需要编码对象块的相邻块的运动矢量等。然而，根据流水线级的结构，可能不能确定运动矢量等。在这种情况下，跳过模式不能应用于编码目标块的压缩编码。本发明旨在解决这个问题，（i）计算编码目标块的所有运动信息候选，对应于由编码目标块的先前块选择的所有运动信息，以及（ii）选择运动信息在所述跳过模式中的所述编码对象块的所述运动信息对应于针对所述前一块确定的运动信息。

摘要： 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.

摘要： While temporal and spatial direct modes are both supported, the amount of temporarily-stored direct-mode prediction information is reduced, thereby reducing the memory bus bandwidth. A motion information generator combines a motion vector for an anchor block with the number of a reference picture of the anchor block, thereby generates motion information of the pixel block. A still-state determination unit determines whether or not the pixel block is considered still based on the motion vector for the anchor block and on the number of the reference picture. A selector selectively stores in a memory either an output of the motion information generator or a determination result of the still-state determination unit as direct-mode prediction information of the pixel block. A motion vector predictor predicts a motion vector for the pixel block in direct mode based on the direct-mode prediction information stored in the memory.
