Abstract
Systems and methods that provide compensation for ambient light in a location of a display device are described. According to various embodiments, a method of compensating for ambient light in a display device is provided. According to the method, an ambient light measurement may be received. The ambient light measurement may include information concerning the intensity of the ambient light present at the location of the display device, the spectrum of the ambient light present at the display device (e.g., color temperature, white balance, or wavelength), and/or both an intensity and a spectrum of the ambient light.
Claims20
A method of compensating for ambient light in a display device, comprising:
- receiving an ambient light measurement, wherein the ambient light measurement comprises intensity information relating to the ambient light in a location of the display device;
- determining an intermediate mapping from a first color space to a second color space based at least on the ambient light measurement;
- remapping a display data for the display device based on the intermediate mapping;
- and
- displaying the remapped data on the display device.
A system configured to modify a gamut of a display device, the system comprising:
- an interface configured to receive an ambient light measurement, wherein the ambient light measurement comprises intensity information relating to ambient light in a location of the display device;
- and
- one or more processors configured to:
- process the ambient light measurement to determine an intermediate mapping from a first color space to a second color space based at least on the ambient light measurement;
- remap a display data for the display device based on the intermediate mapping;
- and
- display the remapped data on the display device.
A display device, comprising:
- an ambient light sensor configured to sense ambient light information, wherein the ambient light information comprises intensity information relating to ambient light in a location of the display device;
- and
- a video system gamut modifier configured to:
- process the ambient light information to determine an intermediate mapping from a first color space to a second color space based at least on the ambient light measurement;
- remap a display data for the display device based on the intermediate mapping;
- and
- a display driver configured to drive a display according to the remapped display data from the video system gamut modifier.
