Abstract
An image evaluation device includes: a partial area extracting section extracting plural partial areas from an original image; an extracted image generating section generating an extracted image corresponding to each of the partial areas and having pixels whose pixel values correspond to a gradient of pixel values in the image; an autocorrelation calculating section calculating plural autocorrelation coefficients for each extracted images; a representative coefficient value calculating section calculating a representative coefficient value for each of the autocorrelation coefficients among the partial areas; and a checking section checking the quality of the image based on a distribution of the representative coefficient values.
