ABSTRACT:
An image-capturing unit generates an image signal corresponding to an image of a subject formed by a photographing optical system. A point spread function generating unit generates varying point spread functions corresponding to various distances based upon two-dimensional distance distribution information indicating the two-dimensional distance distribution of the subject detected by a distance detection unit and an image blur signal indicating an image blur occurring during the exposure period which is detected by a blur detection unit. An image repair unit divides the image signal into partial images based upon the distance distribution information, executes image processing to repair the blur in the individual partial images by using the point spread functions corresponding to the various distances and creates a whole image by synthesizing the partial images in which the blur has been repaired.
