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.
Claims20
A device, comprising:
- an ambient light sensor;
- and
- circuitry configured to
- receive a low ambient light preferred brightness level for a display screen;
- receive a high ambient light preferred brightness level for the display screen;
- set a transition rate at which a brightness level of the display screen transitions between the low ambient light preferred brightness level and the high ambient light preferred brightness level as the ambient light changes;
- store a start time and an end time corresponding to a transition period;
- control the brightness level of the display screen to be at a first default brightness level at the start time;
- control, between the start time and the end time, the brightness level of the display screen to transition from the first default brightness level to a second default brightness level corresponding to the end time;
- receive a user input modifying the brightness level of the display screen during the transition between the first default brightness level at the start time and the second default brightness level at the end time;
- modify the end time based on the received user input;
- and
- control the brightness level of the display screen to transition from the modified brightness level to the second default brightness level at the modified end time.
