Optical device with an image blur suppression function

摘要

An optical device, such as a camera, which includes an image blur suppression optical system to optically prevent image blur of a photographic image on an image plane of the optical device by changes in at least a portion of a photographic optical system. An image blur suppression drive unit drives the image blur suppression optical system, and a suppression position detection unit detects changes in the position of the image blur suppression optical system during the time of the image blur suppression. A lens prime and a memory unit generates constants indicative of optical conditions in the optical device which correspond to changes in the position of the image blur suppression optical system.
