Abstract
In one embodiment, an image is created by combining an overlay image with a main image. Each pixel of the main and overlay images is defined by a luma component and at least one color component. Each luma component takes a value within a luma range, the lowest and highest values in the luma range being, respectively, a minimum and maximum value. For each pixel in the overlay image, it is determined that the pixel is: an opaque pixel, a transparent pixel, or an intermediate pixel. Each pixel of the main image that is in a location that corresponds to the location of an opaque pixel is replaced with the corresponding opaque pixel. In one embodiment, each pixel of the main image that is in a location that corresponds to the location of a transparent pixel is retained. Further, the luma component of each pixel of the main image that is in a location that corresponds to the location of an intermediate pixel is, in one embodiment, replaced with a luma value that is equivalent to the two's complement of the luma value of the corresponding intermediate pixel.
