Data display adapted for bright ambient light

摘要

Systems and method to generate more readable modified images that are presented on electronic displays in bright ambient light, such as direct sunlight. Images normally presented in lower ambient light are modified to generate modified images that have higher contrast and that contain less information. For example, modified images contain pixels that are either “on” or “off” and may be inverted to present a black on white background image on the display. Some information, such as text fields or icons, is removed from the modified image to increase readability in bright ambient light. A backlight level of the display is also able to be increased in bright ambient light.

主权项

1. A method of displaying an image on an electronic device, the method comprising:
performing the following with a processor: receiving an ambient light level indicator; determining that the ambient light level indicator is in a first range; displaying, in response to determining that the ambient light level indicator is in the first range, a first image comprising a first presentation of data of a first data set; determining that the ambient light level indicator is in a second range; selecting, based on determining the ambient light level indicator is in the second range, a selected subset of the first data set, the selected subset of the first data set containing less data than the first data set; generating, based upon the first image, a modified image, the modified image comprising a modified presentation, the modified presentation presenting the selected subset of the first data set; and displaying, in response to determining that the ambient light level indicator is in the second range, the modified image.
