Abstract
The present invention aims at providing a blur correction camera in which an image movement (blur) amount on an image forming plane is displayed more exactly based on the actual states of a camera shake and a blur correcting member. The blur correction camera includes a camera shake sensing section for sensing a camera shake, a blur correcting member for correcting an amount of image movement due to the camera shake, a first image movement amount arithmetic section for calculating an image movement amount on a film plane in response to an output of the camera shake sensing section, a second image movement amount arithmetic section for calculating an image movement amount on the film plane in response to an output of the camera shake sensing section when the image movement amount is corrected by the blur correcting member, and a third image movement amount arithmetic section for calculating a difference between an arithmetic result of the first image movement amount arithmetic section and that of the second image movement amount arithmetic section.
