TRUE COLOR IMAGE ENHANCEMENT COMPENSATION

Abstract: a true color image enhancement system includes an ambient light sensor, a circuit and a processor. the ambient light sensor measures an ambient light level. the circuit generates a histogram based on an input video signal; and generates an output video signal by converting gray shades in the input video signal based on input video luminance ratios and a look up table to determine new output gray shade values to maintain input video color coordinates. the processor develops the look up table based on the histogram and the ambient light level; dynamically remaps the gray shades in the look up table in response to the ambient light signal to compress one region and stretch another region; dynamically remaps the gray shades in the look up table to correct for ambient lighting conditions; and transfers the look up table to the circuit.
