Patent ID: 8300987

Claim:
An integrated circuit comprising: a source image characteristic calculator operative to generate a maximum value map, a minimum value map, an average value map and a difference value map, wherein each pixel value in the average value map represents the average of corresponding pixel locations in the maximum and minimum value maps and wherein the difference value map represents a difference between corresponding values in the maximum and minimum value maps; an upscaler operative to upscale each of the maximum value map, the minimum value map, the average value map and the difference value map to a destination resolution; and a blending module operative to blend pixel values from an upscaled image of a source image with corresponding values of at least one of the upscaled maximum value map and the upscaled minimum value map based on a comparison of each pixel value in the upscaled image with a corresponding pixel value in the upscaled average value map, and wherein each pixel value in the upscaled difference value map provides a known threshold value for determining when the corresponding pixel location in one of the upscaled maximum value map and the upscaled minimum value map contributes to the corresponding pixel in a detail-enhanced upscaled image.
