Abstract

PURPOSE: To simplify the circuit constitution, by using the multiplier adder consisting of the multiplier circuit and the adder/subtractor circuit plus the memory to form the circuit.
CONSTITUTION: With supply of the input picture signal 1, the multiplier adder 17 subtracts the value obtained through multiplication of the output signal of the memory 9 and the constant K2 from the picture signal 1. The signal is supplied to the adder 18 and then receives a subtraction of the value obtained by multiplying the output signal of the memory 6 by the constant K1 to be sent to the adder 19. Then the adder 19 multiplies this signal by the constant K2 and then adds the output signal of the memory 6 to store it newly in the memory 6. On the other hand, the adder 20 multiplies the output signal of the memory 6 by the constant K4 and then adds the signal of the memory 9 to store it newly in the memory 9. Thus the motion picture data and the still picture data are obtained from the memory 6 and the memory 9 each. In such way, the circuit can be simplified by using the multiplier adder.
