Abstract:
A motion vector detecting apparatus for detecting a motion vector relative to an already-coded frame for each of individual blocks into which a frame of image data is divided, comprising:block data storing means for storing pixel data about a number of pixels, pixel data about pixels constituting the blocks;coded data storing means for storing pixel data about pixels lying within a range of rows and of columns in the already-coded frame, as viewed from each of the blocks;selecting means, supplied with a search vector, for selecting pixel data about pixels lying in a range identical in size to each block, at a position spaced from the block in response to the search vector, from the pixel data stored in said coded data storing means;means for comparing the pixel data stored in said block data storing means and the pixel data selected by said selecting means; andmeans for detecting a motion vector based on a comparison by said comparing means.
