A resolution determination section of a resolution determination device includes an edge intensity calculation section that calculates an edge intensity for each of a plurality of pixels in an input image based on the difference between the luminance of the pixel and the luminance of a pixel adjoining the pixel, a coring processing section that brings the edge intensity near to value 0 when the edge intensity is determined to be noise, an edge change point detection section that detects a pixel at which the adjoining edge intensities are different in sign, a first accumulation section that accumulates the detection results for a plurality of pixels, and a second accumulation section that accumulates pixels of which the accumulation value exceeds a parameter value input from outside for one frame. The section determines whether or not the input image is an up-converted image based on the accumulation result.

It is determined whether or not an input image is an image converted from an image with a relatively low resolution based on one frame of an image. A resolution determination device includes: an edge strength calculator configured to obtain an edge strength of a pixel included in an input image based on luminance of the pixel and luminance of a pixel adjacent to the pixel, for each of a plurality of pixels included in the input image; and a resolution determiner configured to determine whether or not the input image is an image upconverted from an image with a predetermined resolution or less, based on distribution of the edge strengths.

Color correction according to the present disclosure performs correction by adding a predetermined correction value to an input value of a component to be corrected, which is one of a plurality of components for representing a color with a predetermined color space, and outputs a corrected value. The color correction includes calculating an unadjusted correction value based on the input value; and adjusting the unadjusted correction value calculated in the calculating the unadjusted correction value so that the corrected value does not decrease with an increase in the input value, and outputting the adjusted value as the predetermined correction value.
