Method and system for improving screen readability in daylight with runtime color adjustment
First Claim
1. A method, comprising:
- in an electronic device;
determining ambient lighting conditions;
determining when the ambient lighting conditions affect display operations in the electronic device;
when the ambient lighting conditions affect display operations in the electronic device, adjusting display operations in the electronic device, the adjusting comprising;
applying to a display of the electronic device, a particular brightness level that is selected based on the determined ambient lighting conditions; and
applying, in combination with the particular brightness level applied to the display of the electronic device, a particular contrast level selected based on the determined ambient lighting conditions, wherein applying the selected contrast level comprises adjusting or modifying a contrast of video content outputted via the display; and
applying contrast adjustments corresponding to the selected contrast level during generation and/or creation of the video content, and wherein applying the contrast adjustments during the generation and/or creation of the video content comprises adjusting text color selection.

Abstract
Display functions in an electronic device may comprise combining runtime color adjustments with brightness adjustments triggered by ambient light detection. Light sensors may be utilized to detect ambient lighting conditions, which may cause adjustment of brightness level applicable to a display (or screen) of the electronic device. The adjustment of brightness level may then be combined with adjustment of contrast level that may also be applicable to display functions. In this regard, a particular contrast level may be selected based on the detected ambient lighting conditions—e.g., by mapping various contrast levels to preconfigured ambient lighting levels. The contrast adjustment may comprise adjusting colors and/or sharpness. Using contrast adjustments, in conjunction with the brightness adjustments, may allow for achieving the same levels of readability with less brightness, and/or for increased readability with the same brightness.
