Abstract:
A method comprising:selecting between a nearest neighbor algorithm and a weighted average linear interpolation algorithm to reduce a source image such that at least one source pixel of the source image is not in a destination image, the selecting being based at least in part on a scaling mode associated with the source image; if the nearest neighbor algorithm has been selected, finding one source pixel among two or more source pixels in the source image that is a nearest neighbor to a destination pixel location in the destination image by using a linear interpolation algorithm with (a) a first distance weight equal to one for the source pixel that is the nearest neighbor to the destination pixel location and (b) a second distance weight equal to zero for one or more source pixels that are not the nearest neighbor to the destination pixel location; and using the source pixel that is the nearest neighbor to the destination pixel location as a destination pixel in the destination image.
