Abstract
PURPOSE:To decide a block with an optimum size by deciding plural kinds of blocks with a required size including picture information, applying inter-frame prediction, moving compensation prediction and inter-frame prediction so as to obtain a prediction error as to each block and evaluating the prediction error by two evaluation means. CONSTITUTION:The block size is made small to a part with rapid pattern change and made large to the flat portion. A 1st evaluation means 17 receives a prediction error from the inter-frame predicting means 14, a prediction error from a movement compensation prediction means 15 and a prediction error from an inter-frame predicting means 16 and evaluates the prediction error by a required evaluation function. Thus, the optimum prediction system is selected and the information is outputted from its output line 17a. Then a 2nd evaluation means 22 receives a means value of the prediction error as to large/ small blocks and evaluates said prediction error by a required evaluation function. Then the optimum block size is decided to output the information from the output line 22a.
