PURPOSE:To execute rapidly picture processing by forming input data multiplied by a constant which may be frequently used and selecting and adding the data multiplied by the constant on the basis of an arithmetic instruction applied from the external. CONSTITUTION:Input picture data are inputted to an arithmetic circuit 20 through a line buffer and a register. The arithmetic circuit consists of plural multiplexers 201, an adder 202 finding out the sum of the outputs of respective multiplexers 201 and an absolute value circuit 203. The outputs of respective registers are multiplied by a constant, the multiplied values are inputted and the space filter processing of the input picture data is executed by switching the multiplexers 201. |
