Abstract
A method and apparatus filter light spectrum. Ambient light conditions of light that is ambient to a user device can be sensed. Ambient light color conditions can be determined based on the sensed ambient light conditions. User device charging times when the user device is being charged can be monitored. User device motion including movement of the user device can be monitored. User device activity can be monitored. Color-modified image display times can be ascertained from at least one selected from the user device motion, the user device activity, and the user device charging times. A color-modified image can be generated based on at least the ambient light color conditions and the color-modified image display times. The color-modified image can be displayed.
