DYNAMIC LIGHT SENSOR AUGMENTED IMAGE ENHANCEMENT

Abstract: an image enhancement system includes an ambient light sensor, a circuit and a processor. the ambient light sensor is operational to measure an ambient light level. the circuit is operational to: generate a histogram based on an input video signal; export the histogram; receive a gray shade look up table; and generate an output video signal by converting multiple gray shades in the input video signal based on the gray shade look up table. the processor is operational to: receive the histogram; develop the gray shade look up table based on the histogram and the ambient light level; dynamically remap the gray shades in the gray shade look up table in response to the ambient light level to compress a first region of the gray shades and stretch a second region of the gray shades; and transfer the gray shade look up table to the circuit.
