PROBLEM TO BE SOLVED: To provide an image processing circuit for executing AAM screen processing (processing including processing for calculating the center of gravity of a gradation value in a cell) at a non-problematical speed on practice. SOLUTION: An image processing circuit 30 for performing AAM screen processing is provided with an input raster buffer 21 for storing "cell size+vertical shift quantity-2" pieces of raster data, and configured (designed, manufactured) as a circuit which performs arithmetic processing relating to the k-th cell in the case of inputting each of the "4k+1"th to "4k+4"th raster data (circuit which performs arithmetic processing relating to the k-th cell in the case of inputting each raster data).
