Abstract A vector quantizer comprises a vector quantization encoder including a subvector register which stores picture signal sequences to be coded, samples every N (N = a plural number) picture signal sequences in blocks to store the input picture signal sequences as input subvectors and a coding code table memory capable of sampling output vectors obtained previously by clustering or the like using picture input signal sequences to form blocks of the output vectors, and a decoder which reads the corresponding output vector by using the index given by the encoder as the address of the output vector from a decoding code table memory storing the output vectors.
