Systems and methods for automated screen color temperature control

An electronic reading device can include an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device can include circuitry configured to determine if a transition between phases has occurred, wherein the phases include a night phase, a sunrise transition p...

Beschreibung
Zusammenfassung:	An electronic reading device can include an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device can include circuitry configured to determine if a transition between phases has occurred, wherein the phases include a night phase, a sunrise transition phase, a daytime phase, and a sunset transition phase, automatically display a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, determine if a brightness level has changed, and automatically adjust a predetermined mixture of light to be displayed via the adjustable RGBW front light such that the screen color temperature does not change in response to the changing brightness level.
