  • Patent number: 5784050
    Abstract: A color space converter that uses a set of simple coefficients to convert data between the RGB and YUV color spaces. The converter utilizes conversion circuitry operable to receive RGB data. The R, G, and B components of the RGB data are then converted into YUV data according to the formulae:Y=1/4R+1/2G+1/4B;U=-1/8R-1/4G+3/8B;V=3/8R-1/4G-1/8B;The YUV data can then be reconverted into the RGB color space by using the formulae:R=Y+2V;G=Y-U-V;B=Y+2U.A preferred embodiment of the present invention is as a VGA controller within a data processing system. The VGA controller is operable to receive data in the RGB color space. The RGB data is then converted into the YUV color space using the above formulae and stored within a memory. The YUV data is retrieved from the memory, converted back into the RGB color space, and then displayed by a display system.
