Auto dimming through camera use
The use of a digital camera in communication with a mobile device to determine the intensity of ambient light conditions is described herein. In one example, the digital camera receives light energy representing ambient light. The intensity of the ambient light is determined and, based upon a comparison of that intensity to a setpoint, the mobile device is reconfigured. In another example, a mobile device is described that uses a digital camera to measure ambient light conditions. The mobile device can be configured in various ways based upon a determination of the intensity and/or wavelengths of the ambient light.
1. A mobile device comprising:
a processor; and
memory, coupled to the processor, the memory having executable instructions stored thereon that when executed by the processor perform operations comprising:
receiving light via an aperture of a digital camera;
determining an intensity of the received light;
comparing the intensity to a setpoint to generate a reconfiguration output; and
reconfiguring a feature of the mobile device based upon the reconfiguration output, wherein reconfiguring comprises:
detecting that the received light comprises light indicative of the color red and the color blue; and
altering one of the light indicative of the color red or blue to a respective other color.
2. The mobile device of claim 1 , wherein the digital camera is a camera that is permanently affixed to the mobile device or a camera that is removable from the mobile device.
3. The mobile device of claim 2 , wherein the camera that is removable from the mobile device is a web camera in communication with the mobile device.
4. The mobile device of claim 1 , wherein the measurement of the received light comprises a measurement and determination of the intensity of the received light in at least one of the electromagnetic spectrum, the visible light spectrum, the infrared light spectrum, the ultraviolet light spectrum, or a specific range of frequencies related to a particular light source.
5. The mobile device of claim 1 , wherein the setpoint is related to the intensity of the received light.
6. The mobile device of claim 1 , wherein the reconfiguration output is an output to increase a backlight level of a display of the mobile device when the intensity of the received light is greater than the setpoint or decrease the backlight level of the display when the intensity of the received light is lower than the setpoint.
7. The mobile device of claim 1 , wherein the reconfiguration output is an output to decrease a backlight level of a keypad of the mobile device when the intensity of the received light is greater than the setpoint or increase the backlight level of the display when the intensity of the received light is lower than the setpoint.
8. The mobile device of claim 1 , wherein the setpoint is based upon an intensity of fluorescent light.
9. The mobile device of claim 8 , the operations further comprising powering down a feature of the mobile device based on a comparison of the received light to the setpoint.
10. The mobile device of claim 9 , wherein the feature comprises a global positioning service.
11. A tangible machine readable storage medium that is not a transient signal per se, the machine readable medium having stored thereon executable instructions that when executed by a machine perform operations comprising:
receiving light via an aperture of a digital camera;
determining an intensity of the received light;
comparing the intensity to a setpoint to generate a reconfiguration output; and
reconfiguring a feature of a mobile device based upon the reconfiguration output, wherein reconfiguring comprises:
detecting that the received light comprises light indicative of the color red and the color blue; and
altering one of the light indicative of the color red or blue to a respective other color.
12. The tangible machine readable storage medium of claim 11 , wherein the digital camera is a camera that is permanently affixed to the mobile device or a camera that is removable from the mobile device.
13. The tangible machine readable storage medium of claim 12 , wherein the camera that is removable from the mobile device is a web camera in communication with the mobile device.
14. The tangible machine readable storage medium of claim 11 , wherein the measurement of the received light comprises a measurement and determination of the intensity of the received light in at least one of the electromagnetic spectrum, the visible light spectrum, the infrared light spectrum, the ultraviolet light spectrum, or a specific range of frequencies related to a particular light source.
15. The tangible machine readable storage medium of claim 11 , wherein the setpoint is related to the intensity of the received light.
16. The tangible machine readable storage medium of claim 11 , wherein the reconfiguration output is an output to increase a backlight level of a display of the mobile device when the intensity of the received light is greater than the setpoint or decrease the backlight level of the display when the intensity of the received light is lower than the setpoint.
17. The tangible machine readable storage medium of claim 11 , wherein the reconfiguration output is an output to decrease a backlight level of a keypad of the mobile device when the intensity of the received light is greater than the setpoint or increase the backlight level of the display when the intensity of the received light is lower than the setpoint.
18. The tangible machine readable storage medium of claim 11 , wherein the setpoint is based upon an intensity of fluorescent light.
19. The tangible machine readable storage medium of claim 11 , the operation further for powering down a feature of the mobile device based on a comparison of the received light to the setpoint.
20. The tangible machine readable storage medium of claim 19 , wherein the feature comprises a global positioning service.
