Abstract
An electronic reading device includes an adjustable RGBW front light and an ambient light sensor. Additionally, the electronic reading device includes circuitry configured to receive a low ambient light preferred brightness level, receive a high ambient light preferred brightness level, and set a rate at which a brightness level transitions between the low ambient light preferred brightness level and the high ambient light preferred brightness level as the ambient light changes.
