摘要

This image capturing assistance device for assisting in capturing an image by an image capturing device comprises: an acquisition unit which acquires a focal length of the image capturing device and an amount of intra-image displacement between a predetermined position within an image obtained by capturing an image of an imaging region by an image capturing element and a position of a subject image indicating a subject; a derivation unit which derives an amount of migration required by a position adjustment unit for adjusting the position of the subject image within the captured image in order to move the position of the subject image to a specific position, on the basis of information pertaining to pixel spacing between pixels in the image capturing element, the intra-image displacement amount acquired by the acquisition unit, and the focal length acquired by the acquisition unit; and an output unit for outputting the migration amount derived by the derivation unit.
