Patent ID: 8374464

Claim:
An apparatus for enhancement of image resolution in which a plurality of low resolution images are received as a set of input low resolution images, which is synthesized to generate a high resolution image, to be output bearing a highest degree of analogy of said set of input low resolution images relative to a set of low resolution images estimated from the high resolution image; said apparatus comprising: a motion estimating unit that estimates motion between pixels of low resolution images to output result of motion estimation; a motion estimation reliability evaluating unit that evaluates reliability of the result of the motion estimation as output by said motion estimating unit and that outputs a motion estimation reliability evaluation value indicating a reliability degree; and a high resolution image estimating unit that estimates a high resolution image to be output by employing an analogy degree calculating method, in performing calculations of said analogy degree, said analogy degree calculation method being in conformity with said motion estimation reliability evaluation value output from said motion estimation reliability evaluating unit wherein: said high resolution image to be output minimizes a sum total of multiplication values calculated by multiplying difference values and corresponding weights based on said reliability of the result of the motion estimation, each difference value being a difference between an input low resolution image and a corresponding image generated using transformation matrix including motion vector and down-sampling.
