First Claim
1. A portable electronic device, comprising:
- a display;
a light sensor; and
a processor configured to;
determine an ambient light color condition based on output from the light sensor;
read a first display-ready image from an image source, the first display-ready image having a first plurality of pixels;
receive clock data and a geographic location of the portable electronic device, the geographic location detected by a GPS unit of the portable electronic device;
adjust a manner in which the first display-ready image is displayed on the portable electronic device by color-shifting at least a subset of the first plurality of pixels based on the ambient light color condition, the geographic location, and the clock data to thereby generate a first color-modified image;
display the first color-modified image on the display of the portable electronic device;
read a second display-ready image from the image source, the second display-ready image having a second plurality of pixels;
adjust a manner in which the second display-ready image is displayed on the portable electronic device by color-shifting at least a subset of the second plurality of pixels based on the geographic location and the clock data, and not based on the ambient light color condition to thereby generate a second color-modified image;
display the second color-modified image on the display of the portable electronic device; and
output, at the display, a user interface operable to receive a user input turning on or off an ambient light matching mode, such that at least the subsets of the first and second plurality of pixels are color-shifted when the ambient light matching mode is turned on, and at least the subsets of the first and second plurality of pixels are not color-shifted when the ambient light matching mode is turned off.

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.
