PROBLEM TO BE SOLVED: To provide an image processor capable of correcting the positional deviation of one line or more of image data by a means by which the small number of virtual pixels are calculated. SOLUTION: The image processor comprises: an image data RGB input means; a density difference detection means for detecting a density difference between a reference color and a color other than the reference color at the same pixel position with one of colors R, G, B as a reference; a peripheral pixel density detection means for performing a density detection means on peripheral pixels; a virtual pixel calculation means for calculating two or more pixels virtually deviating their positions with respect to two colors of a reference pixel and a pixel other than the reference pixel; a pixel-of-interest density difference detection means for operating a density difference of a pixel-of-interest from that of the reference color for all determined data; and an image correction means for detecting image data using data as a result of the virtual pixel detection means on the basis of a result of the pixel-of-interest density detection and a result of the calculation due to the peripheral pixel density detection means.
