Abstract
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.
