Patent ID: 8237852

Claim:
A camera body to which an interchangeable lens is mountable, comprising: an imaging unit operable to generate image data by capturing an object image; an acquisition unit operable to acquire optical data indicating an optical characteristic of the interchangeable lens from the interchangeable lens; a correction unit operable to correct the image data generated by the imaging unit based on the optical data acquired by the acquisition unit; a detection unit operable to detect a state of mounting/demounting the interchangeable lens to/from the camera body; and a display unit operable to display an image based on the image data; wherein, after detecting that the interchangeable lens is completely mounted to the camera body, when the detection unit detects that the interchangeable lens is being demounted from the camera body, the display unit stops displaying the image based on the image data, and when the detection unit subsequently detects that the interchangeable lens is completely demounted from the camera body, the correction unit stops correcting the image data and the display unit displays the image based on the image data.
