Abstract: A method for compressing image information at a high speed and a method for transferring real-time moving images utilizing the same in which scanning of rectangular parallelepiped regions is performed as an extension of three-dimensional Hilbert scanning to improve throughput and to achieve cost reduction. In the method for compressing image information at a high speed, viewed moving images including three dimensional information are converted into one-dimensional serial information one by one using a look-up table associated with rectangular parallelepiped regions in a three-dimensional space, and the converted data is subjected to data compression. In the method for transferring viewed moving images from a server to clients in real-time, data compressed according to the method is transferred through a communication path and the data is decompressed at the clients.
