Abstract
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.
