Abstract:
1. A method for generating dithering patterns associated with a digital image for a display device, comprising: 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; transmitting the first table index value from a computer to a second device via a communication bus; 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; and 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; wherein generating the first dithering pattern comprises: accessing a second table to obtain a first dithering value using a first position value, the first position value being associated with a first pixel of the plurality of pixels; and setting a first pixel value associated with the first pixel either to a high logic level when the first color intensity value is greater than the first dithering value or to a low logic level when the first color intensity value is less than or equal to the first dithering value.
