Abstract: A digital color imager providing an extended luminance range, enabling a method for an easy transformation into all other color spaces having luminance as a component. White pixels are added to hexagonal red, green and blue pixels. These white pixels can alternatively have an extended dynamic range as described by U.S. Pat. No. 6,441,852 (to Levine et al.). Especially the white pixels may have a larger size than the red, green, or blue pixels used. This larger size can be implemented by concatenation of “normal” size hexagonal white pixels. The output of said white pixels can be directly used for the luminance values Y of the destination color space. Therefore only the color values have to be calculated from the RGB values, leading to an easier and faster calculation. As an example chosen by the inventor the conversion to YCbCr color space has been shown in detail.

Abstract: A digital color imager providing an extended luminance range, an improved color implementation and enabling a method for an easy transformation into another color 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 either an extended dynamic rang as described by U.S. Pat. No. 6,441,852 (to Levine et al.) or have a larger size than the red, green, or blue pixels used. The output of said white pixels can be directly used for the luminance values Y of the destination color space. Therefore only the color values and have to be calculated from the RGB values, leading to an easier and faster calculation. As an example chosen by the inventor the conversion to YCbCr color space has been shown in detail.

Abstract: An integrated circuit contains a processor (DSP) for the processing of data, at least two modules (M1, M2, M3) for the processing of data packets selected by the processor according to differing operation regulations, and a router (ROUTER) which is connected to all modules (M1, M2, M3) and to the processor (DSP) for the purpose of controlling the data traffic between the processor (DSP) and the modules (M1, M2, M3). The router is suited to receive from the processor (DSP) data packets and associated instructions, to execute special operations for individual data packets which can be executed by the modules (M1, M2, M3) in specified sequence, to coordinate autonomously the control of the sequences, to transfer the data packets to the appropriate modules (M1, M2, M3), and to transfer the data packets after they have been processed according to the specified instructions to the processor (DSP).
