IMAGE CORRECTION APPARATUS FOR CORRECTING DISTORTION OF AN IMAGE

摘要

An image correction apparatus for correcting distortion of an image, the image being obtained by photographing a subject, which is provided with a specifying unit for specifying a relationship in position between points on the subject in a three-dimensional space based on both a relationship in position between the points on the subject in the image in a two-dimensional space and a photographing angle relative to a surface of the subject, an obtaining unit for obtaining information of distortion of the image that is reflected by the relationship in position between the points on the subject in the three-dimensional space, specified by the specifying unit, and a correcting unit for correcting the distortion of the image based on the information of distortion of the image obtained by the obtaining unit.
