PROBLEM TO BE SOLVED: To provide an image distortion correction method that shortly computes a smoothly varying distortion pattern by interpolating deviations measured by pattern matching at corresponding measurement representative points between a reference image and a compared image.;SOLUTION: The image distortion correction method sets auxiliary representative points other than measurement representative points around an image area to be corrected, corrects a deviation at an auxiliary representative point by extrapolation from deviations measured at nearby measurement representative points, divides all the region of the image area to be corrected into triangles or quadrangles with vertexes on measurement representative points or auxiliary representative points set in the image area to be corrected, and computes a deviation in a triangle or quadrangle by linear interpolation from deviations related to the vertexes of the triangle or quadrangle.;COPYRIGHT: (C)2004,JPO
