Image evaluation device and image evaluation program

摘要

An image evaluation device includes an image acquisition section that acquires an input image to be evaluated, a noise image generation section that generates a noise image that emphasizes noise included in the input image and having a particular spatial frequency that correlates with human perception, a statistic value acquisition section that acquires a predetermined type statistic value from the noise image, and a noise amount specification section that specifies an amount of noise in the input image on the basis of the statistic value.
