ABSTRACT:
In the system of the present invention an individual displayed pixel is a weighted combination of a video pixel and a graphics pixel. For example, a pixel displayed on a monitor may be three-quarters graphics and one-quarter video. In this system a color lookup table providing a red, a green and a blue lookup table output value is extended to provide a further lookup table output value. The further lookup table output value is a weight value representative of the relative weights of a video pixel and a corresponding graphics pixel. The weight value is applied to a matrix multiplier which also receives video pixel information and graphics pixel information. The matrix multiplier determines a weighted combination of the video and graphics pixel information according to the weight value to provide a blended pixel. A YUV standard to RGB standard conversion matrix is provided within in order to receive video signals in a YUV format and apply the video signals to the matrix multiplier in an RGB format.
