Abstract
A photographing device comprises a lens and a camera. The camera body has an imaging device and an image-processing unit that performs distortion correction on the basis of information regarding distortion quantity, as part of an image processing of an image signal obtained by the imaging device through the lens. The distortion quantity has at least one of first distortion quantity of the lens and second distortion quantity of the imaging device. The information has a coefficient of an approximation formula for the distortion correction on a two-dimensional coordinate system for the distortion correction. The two-dimensional coordinate system is set on an image obtained by the image processing of the image signal.
