Dynamic color profile management for electronic devices
First Claim
Patent Images
1. A method comprising:
- periodically determining a white point of ambient light proximate a display;
determining a color profile adjustment for the color space of the display based upon the determined current white point of the ambient light;
dampening a current color profile adjustment based upon one or more previous determined color profile adjustments; and
transforming an image color space to the display color space based on the dampened color profile adjustment of the display so that the white point of the display substantially matches the current white point of the ambient light proximate the display, wherein the color gamut of the display color space is greater than the color gamut of the image color space.

Abstract
Dynamic white point management techniques include determining a white point of ambient light proximate to a display. A color profile adjustment is determined based upon the determined white point and intensity of the ambient light. The image color space is transformed to a display color space for rendering on the display based on the determined adjusted to the color profile.

9. A computing device comprising:
-
a means for determining a current white point of ambient light proximate to a display; a means for determining a color profile adjustment for the color space of the display based upon the determined white point of the ambient light; and a means for transforming an image color space to a display color space based on the determined color profile adjustment so that the white point of the display substantially matched the current white point of the ambient light proximate the display, wherein the color gamut of the display color space is greater than the color gamut of the image color space. - View Dependent Claims (10, 11, 12, 13)

14. A computing device comprising:
-
a display; a light sensor to sense ambient light; and a processing unit to determine a white point of the ambient light sensed by the light sensor, to determine a color profile adjustment for the color space of the display based upon the determined white point of the ambient light, to transform an image color space to a display color space based on the determined color space adjusted and to present content in the display color space on the display so that the white point of the display substantially matched the white point of the ambient light, wherein the color gamut of the display color space is greater than the color gamut of the image color space. - View Dependent Claims (15, 16, 17, 18)
