Abstract:
An image processing apparatus includes: a dispersion calculation unit for calculating a dispersion of pixel values in each of a plurality of pixel groups which are each composed of a pixel of interest and peripheral pixels around the pixel of interest in an image and in which the pixel of interest and the peripheral pixels are arranged in directions different from one another; and a gradation determination unit for determining whether or not the pixel of interest belongs to a gradation region on the basis of a magnitude relationship among the dispersions calculated by the dispersion calculation unit.

Claim (Index 4):
The image processing apparatus according to  claim 3 ,\n wherein the average calculation unit calculates, as a reference average, an average of pixel values of all pixels in a processed region composed of the pixel of interest and peripheral pixels having the pixel of interest as its center, the image processing apparatus further comprises an average-difference calculation unit which calculates absolute values of differences between the respective averages of the plurality of pixel groups and the reference average, and the gradation determination unit determines that the pixel of interest belongs to either of the gradation region and the low-contrast texture region when all of the absolute values calculated by the average-difference calculation unit are equal to or smaller than a predetermined threshold value and determines that the pixel of interest does not belong to both of the gradation region and the low-contrast texture region when at least one of the absolute values calculated by the average-difference calculation unit is larger than the predetermined threshold value.
