Patent ID: 8064734

Claim:
An image processing device for enlarging an image, comprising: an attribute determining unit for determining an attribute of each pixel constituting an input image; a pattern matching determining unit for determining whether a pattern of the input image, constituted by a target pixel and target-pixel-neighboring pixels that are determined to have the same attribute, matches a predetermined interpolation pattern while assuming each pixel of the input image as the target pixel; and a data selecting unit for selecting pixel data for each of N×N pixels, obtained by enlarging the target pixel N-times, on the basis of the result of the matching determination performed by the pattern matching determining unit, where N is an integer equal to or greater than 2, wherein the input image is constituted by an artificial image to be superimposed on a video signal, and wherein the attribute determining unit determines whether or not each pixel of the input image has an attribute indicating the artificial image, and wherein the pattern matching determining unit determines matching of the input image and the interpolation pattern while assuming each of the pixels, determined to have the attribute indicating the artificial image by the attribute determining unit, of the input image as the target pixel.
