Abstract
An image enhancement component of an image processing pipeline preferably uses a single lookup table (LUT) to convert M-bit Red (R), Green (G) and Blue (B) values into respective N-bit R, G and B values, where N is greater than M. Preferably, the N-bit values are determined based on the inverse of an algorithm performed upstream of the image enhancement component by an image correction component. The N-bit R, G and B values provide the image with an improved signal-to-noise ratio (SNR).
