Abstract
A system and a method for generating dithering patterns associated with a digital image are provided. The method includes generating a first table index value indicative of a location in a first table where first, second, and third color intensity values associated with a plurality of pixels on the display device are stored. The method further includes transmitting the first table index value from a computer to a second device via a communication bus. The method further includes accessing the first table using the first table index value to obtain the first, second, and third color intensity values associated with the plurality of pixels, the accessing being performed by the second device. The method further includes generating first, second, and third dithering patterns associated with the plurality of pixels based on the first, second, and third color intensity values, respectively, and position values indicative of positions of the plurality of pixels.
