First Claim
1. A camera comprising:
- an imaging device comprising a plurality of pixels, the plurality of pixels operable to be turned off to save power;
a first pixel in the plurality of pixels operable to turn on when the other pixels in the plurality of pixels are turned off, and when the other pixels in the plurality of pixels are turned off, the first pixel operable to receive a first light beam, the first pixel comprising;
an ambient light sensor operable to receive the first light beam, and detects a plurality of properties associated with the first light beam, the plurality of properties comprising a frequency associated with the plurality of light beams, an amplitude associated with the plurality of light beams, a change in the frequency associated with the plurality of light beams, and a change in the amplitude associated with the plurality of light beams;
a first light guide comprising an entry point and an exit point, the exit point of the first light guide positioned proximate to the ambient light sensor, the first light guide comprising a first tunnel operable to receive the first light beam at the entry point, and operable to transmit the first light beam to the exit point; and
a processor operable to send a unique control signal to the first pixel, the unique control signal comprising an identification associated with the first pixel, and any one of an instruction to turn on or an instruction to turn off.

Abstract
The technology presented here reduces the number of ports associated with the mobile device by combining a plurality of ports into a single multipurpose port. In one embodiment, the multipurpose port includes multiple sensors that detect various properties associated with a light beam, and a light guide that transmits the light beam between the environment outside and the multiple sensors inside the mobile device. In another embodiment, a multipurpose camera includes one or more pixels, different from the rest of the multipurpose camera pixels, where the one or more pixels receive a unique control signal. The unique control signal, sent by a processor coupled to the multipurpose camera, includes an instruction to perform an action different from the rest of the pixels, e.g., to turn on when the rest of the pixels are off. The active pixels can detect coarse properties of the light while saving mobile device battery life.
