Patent ID: 8842741

Claim:
A method for image processing in a video processing device, the method comprising: detecting, in a video image, a scale factor by which said video image has been scaled from a native resolution of said video image in one or both of vertical or horizontal directions based on pixel information for said video image; controlling, based on said scale factor, one or both of a first video noise reduction operation or a second video noise reduction operation, which are utilized for processing at least a portion of said video image; generating a pixel correction value based on one or both of results from said first video noise reduction operation or results from said second video noise reduction operation; and determining said scale factor by which said video image has been scaled from said native resolution based on one or both of a per pixel vertical gradient measurement or a per pixel horizontal gradient measurement, wherein when determining said scale factor, determining which gradient measurements to utilize or which gradient measurements to discard is based on one or more of: configured picture format information associated with said video image; standard deviation of luma levels in one or both of a vertical window or a horizontal window about a current pixel of said video image; and a current pixel location relative to at least one of edges of black borders, graphics, or overlaid content associated with said video image.
