Abstract
Disclosed is a means for adjusting color gamut data associated with a digital media file to compensate for changing ambient light conditions at a display screen. Ambient light conditions at the display screen are detected using a light sensor and converted into ambient light data. Alternate color gamut data is then selected according to the current ambient light data from a color gamut look-up table that contains optimized color gamut data for a variety of ambient light data associated with the digital media file. Display correction parameters are then determined based on the alternate color gamut data. The display correction parameters are applied to present a more optimal rendition of the digital media file. The light sensor periodically re-detects the ambient light conditions so that any changes can be re-processed to update a rendition of the digital media file as it is displayed.
