Abstract
A first derivation unit configured to derive, by performing feature point comparison, first transform information used for coordinate transform between a coordinate system in a whole image obtained by capturing in advance the whole of an object and a coordinate system in a first image obtained by capturing the object; a second derivation unit configured to derive, by performing feature point tracking to track position of a feature point extracted from the first image for a plurality of images input sequentially following the first image, second transform information used for coordinate transform between coordinate system of the first image and coordinate system of a second image of the plurality of images; and a third derivation unit configured to derive third transform information used for coordinate transform between coordinate system in the whole image and coordinate system in the second image by combining first transform information and second transform information.
