Abstract

A moving picture information compressing method and its system for compressing, at high compression rate and at high speed, data such that image information can be prediction-coded and for improving the quality of image. In a first working example, the image in one frame is divided into blocks before the inter-frame compression, and each block is approximated to (replaced with) a single plane defined by three elements of the pixels in the block. In a second working example, the pixel of an original image is compared with that of its decompressed compressed-image, information about the difference of each pixel element is outputted, and the smaller block size is applied if a pixel element which leads to a difference larger than a parameter (threshold) P is present, so as to carry out intra-frame compression. In a third working example, I blocks produced by spatially dividing an image are dispersed along the time axis between frames in such a way that no I block is inserted at a block position in a frame updated when the difference between the frames larger than the parameter (threshold) P occurs in a designated period.
