    • PURPOSE: To make an exact motion vector suitable for creating an interpolating image detectable. CONSTITUTION: In the method to detect a motion vector between a m-th frame(m: arbitrary integer) and a m+n-th frame(n: one or more integer) of the image, a plurality of the 1st block of predetermined size and predetermined shape are extracted from the m-th frame (S101), a plurality of the 2nd block of the same size and the same shape as the 1st block are extracted from the m+n-th frame (S102), a difference absolute value for every corresponding pixel of the 1st block and the 2nd block is obtained (S103), a count value counting number of pixels in which the difference absolute value becomes under a threshold value is obtained (S104), a pair of blocks including blocks which have the maximum count value is extracted from the 1st and the 2nd blocks, and a vector between the block pair is selected as the motion vector between the m-th frame and the m+n-th frame (S105).
    • 目的:使准确的运动矢量适合创建可检测的内插图像。 构成:在图像的第m帧(m:任意整数)和第m + n帧(n:一个或多个整数)之间检测运动矢量的方法中,多个预定的 从第m帧提取尺寸和预定形状(S101),从第m + n帧提取与第一块相同尺寸和相同形状的多个第二块(S102),差异 获得第一块和第二块的每个对应像素的绝对值(S103),获得差分绝对值变为阈值以下的像素数的计数值计数(S104),包括块 从第一和第二块提取具有最大计数值的数据,并且选择块对之间的向量作为第m帧和第m + n帧之间的运动矢量(S105)。
