Patent ID: 8130235

Claim:
A method for adjusting color gamut data associated with a digital media file to compensate for changing ambient light conditions at a display screen when displaying the media file on the display screen, the method comprising: detecting ambient light conditions at the display screen; converting the ambient light conditions to ambient light data; comparing the ambient light data to previous ambient light data to determine a difference value; in response to determining the difference value exceeds a threshold, determining whether a pre-existing color gamut look-up table exists for the digital media file, where a pre-existing color gamut look-up table exists if the digital media file was previously displayed on the display screen; in response to determining a pre-existing color gamut look-up table exists for the digital media file: selecting alternate color gamut data from the pre-existing color gamut look-up table that contains optimized color gamut data for a variety of ambient light data associated with the digital media file, wherein alternate color gamut data is selected according to the ambient light data; determining a replacement color gamut to apply to the display based on the alternate color gamut data; and applying the replacement color gamut to the display to adjust the display to compensate for changing ambient lighting conditions.
