Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  B | IPC B  G

Claim 0:
1. An image enhancement system in a vehicle comprising:
a forward looking light sensor configured to sense a forward looking light seen by a driver of the vehicle while looking over a display to generate a forward luminance value, wherein:
the display includes a first input that receives an enhanced video image and a second input that receives a display luminance value; and
the display luminance value controls a projection light source of the display;

an ambient light sensor configured to sense an ambient light seen by the driver while looking at the display to generate an ambient luminance value; and
an electronic control unit configured to:
calculate the display luminance control value based on the forward luminance value and the ambient luminance value to maintain visibility of the enhanced video image in varying lighting conditions;
present the display luminance control value to the second input of the display;
analyze a video image in a video input signal to determine a plurality of shades of gray within the video image;
adjust the plurality of shades of gray in the video image based on the forward luminance value, the ambient luminance value, and the display luminance control value to generate the enhanced video image; and
present the enhanced video image to the first input of the display.
