Abstract:
1. A method, comprising: receiving a video input from a video source coupled to a display configured for rendering a user interface thereon; evaluating a plurality of pixels within the video input; determining if a particular pixel within the pixels is associated with a color that matches a designated value associated with a chroma-key, wherein if a match is found for the particular pixel, then the particular pixel is rendered as a clear image on the display, and wherein if the match is not found, the particular pixel is darkened by a certain percentage; and wherein the color associated with the particular pixel is represented by a red, green, blue (RGB) value and wherein the RGB value of the particular pixel indicates the certain percentage by which the particular pixel is darkened such that if the RGB value of the particular pixel is a first value, the particular pixel is darkened by a first percentage and if the RGB value of the particular pixel is a second value, the particular pixel is darkened by a second percentage different than the first percentage, and wherein the percentage the particular pixel is darkened is determined without reference to RGB values other than the RGB value of the particular pixel.
