Abstract: PROBLEM TO BE SOLVED: To easily form a mask having no pattern which is inspected as a pseudodefect by detecting a pattern with possibility to be recognized as a defect by mistake and correcting the pattern with possibility to be recognized as a defect by mistake. SOLUTION: When an acute angle is to be detected, a pattern image is inputted (I) and an acute angle as a pattern with possibility to be recognized as a defect by mistake is detected (II).
