Claim Text:
1. An image processing device comprising: a first generating section configured to generate, as first frequency distribution data, frequency distribution data concerning how large luminance differences are between (i) pixels constituting an image and (ii) their respective adjacent pixels; a first determining section configured to determine whether or not a first ratio of a sum of frequencies of classes higher than a predetermined class of the first frequency distribution data to a sum of all frequencies of the first frequency distribution data is equal to or greater than a first predetermined threshold value; a smoothing section configured to perform a smoothing process on the image; and an adjusting section configured to adjust, in a case where the first determining section determines that the first ratio is equal to or greater than the first predetermined threshold value, a smoothing intensity of the smoothing process to be an intensity higher than that of the smoothing process performed in a case where the first determining section determines that the first ratio is less than the first predetermined threshold value, the smoothing section being configured to perform the smoothing process on the image with a smoothing intensity that has been adjusted by the adjusting section.
