Abstract

Embodiments of the present invention can receive a data point defining an ambient light level associated with a display and a corresponding brightness adjustment of the display with respect to a reference brightness. The embodiments can then define a brightness response model for the display based on the data point and at least one additional data point.

Claims

1. A method, comprising:

receiving from at least one ambient light sensor a first measurement of an amount of ambient light in an environment;

receiving, from a user interface, a reference brightness level of a display device, the reference brightness level being associated with the first measurement amount of ambient light;

receiving from the at least one ambient light sensor a second measurement of an amount of ambient light in the environment, wherein the second measurement is not equal to the first measurement; and

automatically adjusting a current brightness level of the display device in response to the second measurement being not equal to the first measurement.

2. The method of claim 1, further comprising:

receiving, from the user interface, a disable command;

the disable command to disable further automatic adjusting of the current brightness level of the display device.

3. The method of claim 2, wherein when the disable command is received, returning the display device brightness level to the received reference brightness level.

4. A non-transitory machine-readable medium having stored thereon instructions, which if executed by a machine causes the machine to perform a method comprising:

receiving from at least one ambient light sensor a first measurement of an amount of ambient light in an environment;

receiving, from a user interface, a reference brightness level of a display device, the reference brightness level being associated with the first measurement amount of ambient light;

receiving from the at least one ambient light sensor a second measurement of an amount of ambient light in the environment, wherein the second measurement is not equal to the first measurement; and

automatically adjusting a current brightness level of the display device in response to the second measurement being not equal to the first measurement.

5. The machine-readable medium of claim 4, wherein the performed method further comprises:

receiving, from the user interface, a disable command, the disable command to disable further automatic adjusting of the current brightness level of the display device.

6. The machine-readable medium of claim 5, wherein the performed method further comprises:

when the disable command is received, returning the display device brightness level to the received reference brightness level.

7. A device, comprising:

a display;

a processor;

a user interface;

at least one ambient light sensor; and

logic to;

receive from the at least one ambient light sensor a first measurement of an amount of ambient light in an environment;

receive, from the user interface, a reference brightness level of the display, the reference brightness level being associated with the first measurement amount of ambient light;

receive from the at least one ambient light sensor a second measurement of an amount of ambient light in the environment, wherein the second measurement is not equal to the first measurement; and

automatically adjust a current brightness level of the display in response to the second measurement being not equal to the first measurement.

8. The device of claim 7, wherein the logic is further operable to:

receive, from the user interface, a disable command, the disable command to disable further automatic adjusting of the current brightness level of the display.

9. The device of claim 8, wherein the logic is further operable to:

when the disable command is received, return the display brightness level to the received reference brightness level.
