Abstract
The human eye is more sensitive to brightness than to color. Accordingly, color definition is defined by a luminance or brightness (Y) component, an in-phase component (I) and a quadrature component (Q) and which are appropriately processed before being converted to more traditional red, green and blue (RGB) components for color display control. Scaling and redesignating YIQ data permits representation by fewer bits than a RGB scheme during processing. Also, Y values may be processed at one level of detail while the corresponding I and Q data values may be processed at a lesser level of detail. Translucency information may also be accommodated.
