Classification: CPC G  B | IPC B  G

Claim 16:
17. A method for display image enhancement in a vehicle comprising:
sensing a forward looking light seen by a driver of the vehicle while looking over a display using a forward looking light sensor 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;

sensing an ambient light seen by the driver while looking at the display using an ambient light sensor to generate an ambient luminance value;
calculating the display luminance control value based on the forward luminance value and the ambient luminance value to maintain visibility of the enhanced video image on the display in varying lighting conditions;
presenting the display luminance control value to the second input of the display;
analyzing a video image in a video input signal to determine a plurality of shades of gray within the video image;
adjusting 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
presenting the enhanced video image to the first input of the display.
