PROBLEM TO BE SOLVED: To improve a processing speed in a various power processing by generating pixel data corresponding to picture data after the various power processing simultaneously for a plurality of picture elements at a high speed. SOLUTION: Pixel data for the prescribed number of picture elements of input picture data are held in a picture data register 101, and outputted in parallel as the pixel data groups. Values which are integral times as large as A being the inverse number of designated magnification are held in parameter registers 104-119. Carry generators 120-134 add an offset value Y to the value of each parameter register 104-119. Incrementors 135-148 add carry values from the carry generators 120-134 to the integral parts of the values stored in the parameter registers, and outputs the result to selectors 149-163. The selectors 149-163 select any of the above pixel data groups, based on the inputted values, and outputs it. Thus, the pixel data of the picture data after the various power processing can be simultaneously outputted for the plurality of picture elements. |
