摘要：An image information compressing method for densely compressing image information, in particular, dynamic image information, a compressed image information recording medium for recording compressed image information, and a compressed image information reproducing apparatus capable of reproducing compressed image information at high speed in a short time are provided. Each image frame constituting a dynamic image information is divided into key frames and movement compensation frames. The key frame is divided into blocks so that an image pattern of each block is vector-quantized by using a algorithm of the Kohonen's self-organizing featured mapping. The movement compensation frame is processed such that a movement vector for each block is determined and a movement vector pattern constituting a large block is vector-quantized by using the algorithm of the Kohonen's self-organizing featured mapping. The compressed image information recording medium includes an index recording region for recording the representative vector number of each block and large blocks and a representative vector recording region for recording information
corresponding to a code book. The compressed image information reproducing apparatus includes a data reading unit, a key frame restoring unit and a movement compensation frame restoring unit.
