Abstract:
1. An image processing apparatus for converting an input image having a first resolution into an output image having a second resolution higher than the first resolution, comprising: super-resolution (“SR”) processing means for converting the input image into an SR image having the second resolution through motion compensation using the input image and another input image having the second resolution and containing an image of a subject the same as that contained in the input image; motion mask generating means for generating a motion mask indicating an accuracy of estimation through the motion compensation using the input image and the SR image; edge direction information generating means for generating edge direction information indicating an edge direction of each area of the input image; weight map generating means for generating a weight map indicating likelihood of the edge direction of each of the areas using the input image and the edge direction information; interpolation processing means for converting the input image into an interpolated image having the second resolution through interpolation processing using the edge direction information; weight computing means for computing a weight using the motion mask and the weight map; and image generating means for generating the output image by constructing a weighted sum of the SR image and the interpolated image using the weight.
