Abstract
An imaging device according to the present invention includes: an image-capturing optical system forming an image of a subject on a surface of an image sensor; a blur-detecting unit detecting a blur of an optical axis in the image-capturing optical system; an image-capturing unit which divides a total exposure time by a predetermined dividing number to repeat image capturing, and generates a number of images corresponding to the dividing number; and a composing unit which finds a motion vector based on the images in the dividing number generated by the image-capturing unit and on the blur detected by the blur-detecting unit and composes the generated images in the dividing number based on the motion vector. Therefore, it is possible to precisely correct a blur while shortening the time required for the blur correction.
