PROBLEM TO BE SOLVED: To provide a shake detection device, a shake correction camera and an interchangeable lens capable of reducing the influence of parallax between an optical system for a shake sensor and a photographing optical system. SOLUTION: When a subject distance is infinity, the optical axis I of the photographing optical system 10 becomes nearly parallel with the optical axis I' of the optical system for detecting shake 17, and an image in the center of a photographic image plane is positioned in the center of an image pickup range 191. Therefore, image data within the range 191 is selected to arithmetically calculate,shake amount. When the subject distance is a short distance, the optical axis I' is inclined to the optical axis I and the parallax is caused between the optical systems 10 and 17. As a result, the image in the center of the photographic image plane is positioned in the center of the image pickup range 192 not the range 191. Therefore, the image data within the range 192 is selected to arithmetically calculate the shake amount. Thus, the image pickup range is moved in an X-axis direction so as to arithmetically calculate the shake amount based on a part of the image data. |
