PURPOSE:To execute an image processing with the arbitrary edge sharpness of an operator by transforming attention picture element data and peripheral picture element data to be supplied by using a transformation coefficient, and adding the respective transformed pixel data. CONSTITUTION:The picture element data inputted to a flip-flop 10 are held for one clock, inputted to a transformation RAM 20 as image data ID00 and simultaneously inputted to a flip-flop 13 as well. In this case, transformation RAM 20-28 execute data transformation at the value of respectively written filtering coefficients according to a fixed rule, and image data ID00-ID22 inputted to the transformation RAM 20-28 are respectively outputted to and adder part 5 as transformed data CD00-CD22. The adder part 5 calculates the total of the inputted transformed data CD00-CD22 and outputs a filtering process signal ODAT to an output device. |
