Patent ID: 7760237

Claim:
An imaging device comprising: a blur-detecting unit which detects a blur of a device; a decision unit which decides whether a value indicating an exposure time is larger than a reciprocal of a value indicating a focal length of an image-capturing optical system forming an image of a subject of a surface of an image sensor; an image-capturing unit which obtains a number of images by dividing said exposure time by a predetermined dividing number and repeats image capturing to generate a plurality of images according to the number of images, when said decision unit decides that the value indicating said total exposure time is larger than the reciprocal of the value indicating the focal length of said image-capturing optical system; and a composing unit which finds a motion vector according to the plurality of images generated by said image-capturing unit and to said blur detected by said blur-detecting unit, and composes the generated plurality of images according to said motion vector.
