System for providing color balance in automotive display
A display system may include a camera configured to capture an image of a calibration reference associated with an automobile, a display, and a controller in communication with the camera and the display. The controller may be configured to selectively adjust a color temperature of the display based on the image of the calibration reference.
1. A display system for an automobile, comprising:
a camera configured to capture an image of a calibration reference associated with the automobile;
a display; and
a controller in communication with the camera and the display, the controller being configured to selectively adjust a color temperature of the display based on the image of the calibration reference;
wherein: the camera is a first camera directed to a first area of the automobile to capture a first image;
the display is a first display located in the first area of the automobile;
the display system further includes: a second camera directed to a second area of the automobile to capture a second image; and a second display located in the second area of the automobile; and
the controller is configured to adjust the color temperature of the first display based on the first image independent of adjustment of the color temperature of the second display based on the second image.
2. The display system of claim 1 , wherein: the camera is directed toward a driver location inside the automobile; and the display includes an instrument cluster mounted inside a driver area of the automobile.
3. The display system of claim 2 , wherein the camera is a driver-fatigue camera.
4. The display system of claim 1 , wherein: the camera is directed toward a rear-seat passenger area inside the automobile; and the display includes an entertainment display mounted in the rear-seat passenger area of the automobile.
5. The display system of claim 4 , wherein the camera is a child monitor camera.
6. The display system of claim 1 , wherein the display includes cabin lighting.
7. The display system of claim 1 , wherein: the camera is directed toward an exterior of the automobile; and the display includes an exterior trim light.
8. The display system of claim 7 , wherein the camera is one of a traffic monitoring camera and a backup camera.
9. The display system of claim 1 , wherein the controller is configured to apply a filter to adjustments made to the image.
10. The display system of claim 9 , wherein the filter is one of a rate of adjustment filter or an averaging filter.
11. The display system of claim 1 , wherein: the calibration reference has a known color temperature under calibration lighting; and the controller is configured to adjust the color temperature of the display based on a difference between a detected color temperature of the image and the known color temperature.
12. The display system of claim 11 , wherein the calibration reference is one of a seat, an interior door panel, an exterior body panel, or a bumper of the automobile.
13. A method of controlling a display of an automobile, comprising:
capturing an image of a calibration reference associated with the automobile; and
selectively adjusting a color temperature of the display based on the image of the calibration reference;
wherein: capturing the image of the calibration reference includes capturing a first image of a first calibration reference in a first area of the automobile;
the method further includes capturing a second image of a second calibration reference in a second area of the automobile; and
selectively adjusting the color temperature includes selectively adjusting the color temperature of a first display based on the first image independent of adjusting the color temperature of a second display based on the second image.
14. The method of claim 13 , wherein:
capturing the image of the calibration reference includes capturing an image of a driver location inside the automobile; and
the display includes an instrument cluster mounted inside a driver area of the automobile.
15. The method of claim 13 , wherein:
capturing the image of the calibration reference includes capturing an image of a rear-seat passenger location of the automobile; and
the display includes an entertainment display mounted in a rear-seat area of the automobile.
16. The method of claim 13 , wherein: capturing the image of the calibration reference includes capturing an image of an exterior of the automobile; and the display includes an exterior trim light.
17. The method of claim 13 , further including filtering adjustments to be made to the color temperature of the display based on at least one of a rate of adjustment and an average of color temperatures.
