    • An image processing apparatus, wherein image data is stored in a current block memory and image data of a search range of a reference picture is stored in a search window memory. Using a gray code, the register file of the search window memory is read, candidate blocks are successively extracted, and the image data is successively input to processor elements. The data stored in the current block memory is input to a register and input through a barrel shifter to the processor elements. The processor elements find the differences of the current block and candidate blocks, find the cumulative values, compare the cumulative values of differences at a comparison unit, extract the candidate block giving the smallest value, and detect the motion vector based on the candidate block.
    • 一种图像处理装置,其中图像数据被存储在当前块存储器中,并且参考图像的搜索范围的图像数据被存储在搜索窗口存储器中。 使用灰色代码,读取搜索窗口存储器的寄存器文件,连续提取候选块,并将图像数据连续地输入到处理器元件。 存储在当前块存储器中的数据被输入到寄存器并通过桶形移位器输入到处理器元件。 处理器元件找到当前块和候选块的差异,找到累积值,比较比较单元处的差异的累积值,提取给出最小值的候选块,并且基于候选块检测运动矢量。
