Patent ID: 7791662

Claim:
An image processing device, comprising: image acquisition means, for acquiring a plurality of image data sets configured of a plurality of pixels disposed in array fashion and having subject distortion due to focal plane shutter effects and corresponding to taken images taken at continuous exposure timings; coefficient storage means for storing particular coefficients, said coefficients being determined by which number-in-order of a plurality of images that said image data set, acquired by said image acquisition means, corresponds to, and determined by each pixel position in said image; multiplying means for multiplying a pixel value of a predetermined pixel in said image data sets, acquired by said image acquisition means, by said particular coefficient stored in said coefficient storage means; and adding means for adding each pixel value of a predetermined number of said image data sets, including said image data sets having said pixels which have been multiplied by said particular coefficients by said multiplying means; wherein said particular coefficients stored in said coefficient storage means include a coefficient wherein, at said image data set taken at the earliest point-in-time of said image data sets subjected to addition by said adding means, pixels exposed at an early point-in-time are weighted less and pixels exposed at a late point-in-time are weighted more, and a coefficient wherein, at said image data set taken at the latest point-in-time of said image data sets subjected to addition by said adding means, pixels exposed at an early point-in-time are weighted more and pixels exposed at a late point-in-time are weighted less.
