ABSTRACT:
A device and method for converting 18-bit RGB data to 5-bit gray scale data is disclosed. This device and method comprises a barrel shifter, an adder, a palette storage register, and control logic. The red data is loaded first into the barrel shifter, and is shifted, added and stored in the palette storage register. The green data is then loaded into the barrel shifter and is shifted and added to the value stored in the palette storage register. The blue data is then loaded into the barrel shifter and is shifted and added to the value stored in the palette storage register, thereby completing the conversion. The five most significant bits of the six-bit palette storage register are output as gray scale data. The shifting and adding of these six-bit integers allow a binary approximation of the appropriate coefficients for each block of color data.
