DISTORTION CORRECTION FOR PHOTOGRAPHING DEVICE
First Claim
1. A photographing device comprising:
- a lens; and
a camera body that 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 said imaging device through said lens;
said distortion quantity having at least one of first distortion quantity of said lens and second distortion quantity of said imaging device, said information having a coefficient of an approximation formula for said distortion correction on a two-dimensional coordinate system for said distortion correction, said two-dimensional coordinate system being set on an image obtained by said image processing of said image signal.

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.
