Abstract
A dynamic edge enhancement system includes a light sensor, a circuit, and a microcontroller. The light sensor is operational to generate a light background signal by measuring an ambient light falling on a display. The circuit is operational to generate a histogram of gray shade values in multiple frames of an input video signal received by the circuit, detect multiple edges in the input video signal, enhance the multiple edges in response to a gray shade transfer table and an edge mask strength value, and generate an output video signal suitable to drive the display after the enhancement of the edges. The microcontroller is operational to generate the gray shade transfer table based on the histogram generated by the circuit, and generate the edge mask strength value in response to the gray shade transfer table, the light background signal, a night luminance threshold value, and a day luminance threshold value.
