摘要： In an image coding and decoding device, input digital image signals are divided into blocks of prescribed size, and coding processing is performed to differential signal taken between the input block signal and interframe forcasting signal thereby transmission recording is performed.

摘要： A vector quantizer which transmits the input vector of the time when the minimum distortion is larger than the preset distortion threshold value and stores such input vector into the second code book as the new quantizing representative vector for the use in the successive vector quantizing processes. Further, since the first and second code book constitute in the form of tree-structure, calculation for search may be executed at a high speed.
