System zur Verarbeitung eines quantisierten Vektors.

摘要

A quantized vector decoder (60; Fig. 1), a method of making the code book (5a, 5b) therefor, a system for transferring quantized vector, and an image processing apparatus (Fig. 6) utilizing the vector quantization are disclosed, the quantized vector being arranged to decode codes, which have been formed by vector-quantizing vectors formed of collecting a plurality of data items correlating to one another into output vectors, the decoder comprising: an input device (7; Fig. 1) for receiving the codes; a code book tb; Fig. 1) for previously storing the output vectors of the vector-quantized codes, each of the output vectors in the code book being constituted by a first output-vector component portion and a second output vector component portion; a retrieval device for retrieving the output vectors in the code book depending upon the correspondence between an input code and the first output-vector component portion; and an output device for transmitting the retrieved output vectors in the form of a combination of their first and second output vector component portions.
