ABSTRACT:
An image processing device for enlarging an image includes an attribute determining unit, a pattern matching determining unit, and a data selecting unit. The attribute determining unit determines an attribute of each pixel constituting an input image. The pattern matching determining unit determines 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 pixels of the input image as the target pixel. The data selecting unit selects 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.
