<p>PROBLEM TO BE SOLVED: To clearly represent vertexes of three right angles to eliminate the swelling of a black part by a protrusion thereof during generating a two-dimensional code with a printer.SOLUTION: An image processor has generation means which preliminarily holds four patterns of a square composed of four minimum cells being three black cells and one white cell for a two-dimensional code of a minimum unit to detect vertexes of three right angles by being compared with the four patterns, and generates a two-dimensional code in which one cell is composed of a plurality of pixels, wherein black pixels in four pixels brought into contact with the detected vertexes of the three right angles are equal to or less than two pixels by allocating black pixels that are not included in coincident square patterns.</p> |
