Super-resolution device and method

摘要

A super-resolution device and method for setting at least one of a plurality of pixels included in image data as target pixels, the image data including pixels arranged in a screen and pixel values representing brightness, an area including the target pixel and peripheral pixels as a target area, and an area for searching pixel valu change patterns in the target pixel area; calculating a difference between a first change pattern and second change pattern; comparing a difference.between the first and second change patterns; calculating a pixel value of a super-resolution image having a. number of pixels larger than a number of pixels included in the image data on the basis of a decimal-accuracy-vector, an extrapolated vector, and pixel values obtained from the image data.
