Abstract

PURPOSE: To simplify the memory control and to reduce the cost of the encoder by storing an in-block data of an existing frame data and an in-block data being a preceding frame data respectively in parallel and outputting them simultaneously.
CONSTITUTION: An existing frame data 1 is written in an existing frame memory 2 and a preceding frame data 4 is written in a preceding frame memory 5. A data converter 7 replaces the sequence of data and outputs the result to a distortion computing element 9 as preceding frame replacement data 800, 810, 820,...823, 833. A moving quantity (x0, y0) is changed in response to a retrieval number outputted from a retrieval number counter 18 and when all evaluation functions 10 at one retrieval point are calculated, the retrieval number counter 18 is incremented. Then the evaluation function of the succeeding retrieval point is calculated, A distortion detector 11 outputs the moving quantity (x0, y0) corresponding to the minimum evaluation function 10 as a moving vector.
