Abstract
PURPOSE: To obtain a method and device capable of vector quantization with the operation merely reading from a table to input vector data by previously storing a representative number to be outputted into a storage device in correspondence to an input vector using the digital value of the input vector as an address. CONSTITUTION: Input vector data are specified to be e.g. respective four- dimensional eight bits of C. M, Y and K, and a RAM 4 for a four-dimensional lookup table(LUT) is specified to be a memory making data an address value. On the other hand, the representative vector number to the address value previously obtained by processing in accordance with the kind of data is housed in a table file 6 together with a code book. A prescribed table is read from the table file 3 to the RAM 4 in accordance with the kind of data. Then the representative vector number corresponding to the address is read with a LUT selecting arrangement 5 and transmitted as an output together with the code book.
