Abstract:
1. A method for modifying color data in a display system, the method being implemented using hardware circuitry, the method comprising: receiving, using the hardware circuitry, first-color data associated with a first bit depth, the first-color data including a first-color data value; receiving, using the hardware circuitry, second-color data associated with a second bit depth, the second-color data including a second-color data value that corresponds to the first-color data value, the second bit depth being less than the first bit depth; normalizing, using the hardware circuitry, the second-color data according to the first bit depth for generating normalized second-color data; adding, using the hardware circuitry, a first offset value to each data value of the normalized second-color data to generate offset second-color data, the offset second-color data including an offset second-color data value that corresponds to the first-color data value and the second-color data value; determining a modified second-color data value using the hardware circuitry, the first-color data value, and the offset second-color data value; and providing the first-color data value and the modified second-color data value for displaying an image.
