An object is to obtain three-dimensional shape data with high accuracy from three-dimensional shape data representing an approximate shape of an object. Three-dimensional shape data of an object existing in an image capturing space is obtained. Further, a plurality of distance images each representing a distance to the object and corresponding to a plurality of viewpoints is obtained. Then, correction to evaluate the three-dimensional shape data based on the plurality of distance images and based on results of the evaluation, delete a unit element estimated not to represent a shape of the object among unit elements configuring the three-dimensional shape data is performed.
