摘要：A digital color imager providing an extended luminance range, an improvedcolor implementation and enabling a method for an easy transformation into anothercolor space having luminance as a component has been achieved. Key of the invention is
the addition of white pixels to red, green and blue pixels. These white pixels have eitheran extended dynamic rang as described by US patent (6,441,852 to Levine et al.) or have alarger size than the red, green, or blue pixels used. The output of said white pixels can bedirectly used for the luminance values Y of the destination color space. Therefore onlythe color values and have to be calculated from the RGB values, leading to an easier andfaster calculation. As an example chosen by the inventor the conversion to YCbCr colorspace has been shown in detail.
