<p>PROBLEM TO BE SOLVED: To generate a dynamic image in which fixed pattern noise is hardly perceived.SOLUTION: Noise dispersion is derived on the basis of an exposure condition at image capture time, a noise image is generated in which white noise corresponding to the noise dispersion is superposed on fixed pattern noise. Information about a spatial frequency having sensitivity to the moving speed of a subject in human visual perception is extracted from each of the fixed pattern noise map and the noise image, and the fixed pattern noise map and the noise image are divided for each of a plurality of spatial frequency bands. The noise image divided for each of the plurality of spatial frequency bands is masked on the basis of the fixed pattern noise map divided for each of the plurality of spatial frequency bands and synthesized, then the amount of fixed pattern noise perception is calculated.</p> |
