Abstract
In scaling an image, a projected position is corrected in accordance with pixel values of original pixels surrounding a projected position where a pixel of a scaled image is projected onto an original image, and a pixel value of a pixel of a scaled image is determined in accordance with pixel values of original pixels surrounding a projected position after correction. Further, when a pixel of an original image is processed with a pixel run as a unit, coordinates of an end pixel of a pixel run in a scaled image are corrected based on the width of the pixel run and a scale factor.
