PROBLEM TO BE SOLVED: To improve plotting quality by the anti-alias processing of an image processor. SOLUTION: This image processor comprises an image memory 12 including a first color buffer 13 and a second color buffer 14 for storing the data of pixels configuring a polygon and an identification ID storing buffer 15, an identification ID generating block 6 for imparting to each pixel identification ID for identifying whether or not each pixel is present on the edge of the polygon, and a memory control block 8 for storing the identification ID of each pixel in the identification ID storing buffer, and for receiving the coordinates, color value, polygon coating rate, and identification ID of each pixel, and for mixing them according to the polygon coating rate of the pixel on the basis of the color value of the pixel and the color value stored in an address on the second color buffer corresponding to the pixel to determine a final color value, and for storing it in the first color buffer.
