Ambient light context-aware display
First Claim
1. A portable electronic device comprising:
- a display;
a light sensor configured to sense an ambient light color condition;
a processor configured to;
determine an ambient light history including a plurality of ambient light color conditions, including a plurality of correlated color temperatures and luminance data, sensed over a duration of device operation by a light sensor;
read a display-ready image from an image source, the display-ready image having a plurality of pixels;
adjust a manner in which the display-ready image is displayed on the portable electronic device by color-shifting at least a subset of the plurality of pixels based on the plurality of ambient light color conditions in the ambient light history to thereby generate a color-modified image, wherein color-shifting the subset of the plurality of pixels includes adjusting white points of the subset of the plurality of pixels;
display the color-modified image on the display of the portable electronic device;
detect a threshold brightness decrease during a predetermined time period based on the luminance data in the ambient light history; and
apply a dimming pattern with a target brightness that varies with time to effect a graduated dimming of the brightness of the display over a predetermined time in response to the detection of the threshold brightness decrease.

Abstract
Embodiments are disclosed that relate to modifying a display of a portable electronic device to account for ambient light. For example, one disclosed embodiment provides a method comprising determining an ambient light history including a plurality of ambient light color conditions sensed over a duration of device operation by an ambient light sensor, reading a display-ready image having a plurality of pixels from an image source, adjusting a manner in which the display-ready image is displayed by color-shifting at least a subset of the plurality of pixels based on the plurality of ambient light color conditions in the ambient light history to thereby generate a color-modified image, and displaying the color-modified image on the display of the portable electronic device.

18. A method for adjusting a display to account for ambient light, the method comprising:
at a portable electronic device; receiving ambient light data from an ambient light sensor, the ambient light data including ambient color data indicating an ambient light condition external to the portable electronic device and luminance data; receiving contextual data from a contextual data source; reading a display-ready image from an image source, the display-ready image having a plurality of pixels; modifying one or more properties of at least a subset of the plurality of pixels based on at least the ambient light data and the contextual data; displaying the modified display-ready image on the display; detecting a threshold brightness decrease during a predetermined time period based on the luminance data; and applying a dimming pattern with a target brightness that varies with time to effect a graduated dimming of the brightness of the display over a predetermined time in response to the detecting of the threshold brightness decrease.
