    • A moving image encoding apparatus includes a motion vector detecting unit for executing from a wide and coarse search to a narrow and fine search in a plurality of steps and in a stepwise manner to detect a motion vector of each block in an input image. The motion vector detecting unit includes a block combining unit for generating a combination block, depending on a result of detection in a search step, a search use pixel extracting unit for extracting a search use pixel to be used in a next search step, from the combination block, and a second search combination block searching unit for performing the next search step with respect to the combination block using the search use pixel, and setting a detected motion vector of the combination block as the motion vector of each block of the combination block.
    • 运动图像编码装置包括:运动矢量检测单元,用于从多个步骤中以逐步的方式从广泛粗略搜索到窄和精细搜索,以检测输入图像中每个块的运动矢量。 运动矢量检测单元包括:块组合单元,用于根据搜索步骤中的检测结果生成组合块;搜索使用像素提取单元,用于从下一个搜索步骤中提取要使用的搜索使用像素 组合块和第二搜索组合块搜索单元,用于使用搜索使用像素执行关于组合块的下一个搜索步骤,并且将检测到的组合块的运动矢量设置为组合块的每个块的运动矢量 。
