Abstract
A PC acquires a plurality of images along a rotating direction of an inspection target with a linear sensor at predetermined time intervals ΔTI, extracts position change information representing a change in an on-image position of a pixel having a predetermined feature value or a predetermined pixel value of the acquired images arranged along a time lapse, and generates information on correspondence between the position of the pixel in each of the images and an angle of rotation of the inspection target from the position change information.
