    • An amount-of-movement detection device which is capable of detecting the amount of movement with a high degree of accuracy when the amount of movement of an image is detected by hierarchical block matching method. An amount-of-movement detection device 1 forms image data S2.sub.n and S3.sub.n of plural hierarchies having different resolutions from each other, by input image S1.sub.n input at a first point in time, and forms multiplexed image data S2.sub.n-1 and S3.sub.n-1 of a higher hierarchy of low resolution, based on an input image S1.sub.n-1 input at a second point in time, by selecting pixels overlapping with each other from the image data of the lower hierarchy having higher resolution and reducing them in size, in order to detect a motion vector by block matching at a predetermined block unit for each of the hierarchies corresponding to the hierarchized image data S2.sub.n and S3.sub.n and the multiplexed and hierarchized image data S2.sub.n-1 and S3.sub.n-1. Thus, the accuracy in the detection of an amount of movement can be greatly enhanced.
    • 一种移动量检测装置,其能够通过分层块匹配方法检测图像的移动量​​时以高精度检测移动量。 移动量检测装置1通过在第一时间点输入的输入图像S1n形成具有不同分辨率的多个层次的图像数据S2n和S3n,并且形成多个图像数据S2n-1和S3n-1 基于在第二时间点输入的输入图像S1n-1,通过从具有较高分辨率的较低层次的图像数据中选择彼此重叠的像素并将其尺寸减小,从而更低层次的低分辨率,以便 对于与分级图像数据S2n和S3n以及多路复用和分层图像数据S2n-1和S3n-1相对应的每个层级,以预定块单位的块匹配来检测运动矢量。 因此,可以大大提高检测移动量的精度。

    • In each of the memory cell arrays in the memory banks, a memory cell row corresponding to each of the word lines extending in a column direction of each of the memory cell arrays store pixel data of each pixel block of first and second rows set in a horizontal way in a search area within a search frame of picture signal. The pixel data of a predetermined pixel block is selectively captured into each of the data buffer through the sense amplifiers and the switches. Selector sequentially extracts pixel data as candidate blocks based on the pixel data of two pixel blocks held in each of the data buffers. The matching circuit matches the pixel data as the extracted candidate blocks against the pixel data as the input reference block using the block-matching process to obtain a motion vector relative to the reference block.
    • 在存储器组中的每个存储单元阵列中,对应于每个存储单元阵列的列方向上延伸的每个字线的存储单元行存储设置在存储单元阵列中的第一和第二行的每个像素块的像素数据 在图像信号的搜索帧内的搜索区域中的水平方向。 通过读出放大器和开关将预定像素块的像素数据选择性地捕获到每个数据缓冲器中。 基于保持在每个数据缓冲器中的两个像素块的像素数据,选择器依次提取像素数据作为候选块。 匹配电路使用块匹配处理将像素数据作为提取的候选块与像素数据进行匹配,作为输入参考块,以获得相对于参考块的运动矢量。
