Abstract

PURPOSE:To obtain superior pictures with a simple constitution, by using prescribed filter parameters to operate the matrix picture element string obtained by reading the picture to be processed. CONSTITUTION:RAMs 501-503 where digital signal Si obtained by scanning the picture is stored divisionally, gates 511-513 which gate outputs of RAMs 501-503, and control circuit 500 are provided in the picture processing unit. Outputs of gates 511-513 are applied to OR circuits 521 523, and outputs of circuits 521-523 are applied to multipliers 531-533 with filter factors F-1, F0 and F1 set respectively to multiply them, and outputs of multipliers 531-533 are added by adder 540 to output picture S0. In respect to three picture elements Xi-1, Xi and Xi+1 in the direction where the MODULATION TRANSFER FUNCTION value is not good, filter factors F-1-F1 are used to operate expression I, and these factors are set to any of expressions II.
