Apparatus used for image blur prevention

A control apparatus for an image blur prevention apparatus adapted to an optical apparatus having an optical device, light receiving means for receiving light from the optical device, and image processing means for processing light received from the light receiving means in accordance with an image processing condition to form a photographic image, the image blur prevention apparatus comprising image blur prevention optical means for optically preventing an image blur of the photographic image, said control apparatus comprising:

• a variable portion that changes an image blur prevention characteristic of the image blur prevention apparatus in accordance with a change in an image processing condition of light received by the light receiving means, wherein when the light is processed in accordance with a change in the image processing condition that increases an influence of an aberration upon operation of the image blur prevention optical means, said varying portion changes an image blur prevention characteristic of the image blur prevention optical means so as to substantially eliminate the aberration.

A control apparatus for an image blur prevention apparatus adapted to an optical apparatus having an optical device, light receiving means for receiving light from the optical device, and image processing means for processing light received from the light receiving means in accordance with an image processing condition to form a photographic image, said control apparatus comprising:

• a variable portion comprising means for changing an image blur prevention characteristic of the image blur prevention apparatus in accordance with a change in the magnification of the image, wherein said variable portion comprises means for changing the image blur prevention characteristic of the image blur prevention apparatus in accordance with a discrimination result as to whether the image is processed optically or electronically.
