PROBLEM TO BE SOLVED: To easily estimate the size of an imaging device used in generating images. SOLUTION: An image processor acquires real focal length information as information representing focal length, when imaging a target image generated by an imaging device having the imaging device, and conversion focal length information representing conversion focal length obtained, by converting real focal length as focal length corresponding to a virtual reference image formation face of a prescribed size. The imaging processor also acquires information, representing the size of the reference image formation face. The image processor estimates the size of the imaging device, on the basis of the real focal length information, the conversion focal length information and the information, representing the size of the reference image formation face.
