Abstract

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.

Claims

1. A method comprising:

receiving light via an aperture of a 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.

2. The method of claim 1, wherein the camera comprises one of:

a camera that is permanently affixed to the mobile device;

or

a camera that is removable from the mobile device.

3. The method of claim 1, wherein the camera comprises a web camera in communication with the mobile device.

4. The method 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 method of claim 1, wherein the setpoint is related to the intensity of the received light.

6. The method 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 method 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 method of claim 1, wherein the setpoint is based upon an intensity of fluorescent light.

9. The method of claim 1, further comprising powering down a feature of the mobile device based on a comparison of the received light to the setpoint.

10. The method of claim 9, wherein the feature comprises a global positioning service.
