    Abstract: An imaging system includes a plurality of pixels. A pixel readout circuit produces a plurality of first image frames from those pixels. An image output circuit produces a plurality of second image frames and operates to produce a second image frame from more than one of the first image frames. The pixel readout circuit is enabled to produce the first images frames at a rate faster than the image output circuit produces the second image frames. Through combining first image frames, by averaging or other statistical combinations, the photon shot noise of second image frames is reduced. Photon shot noise affects images with high light levels more than those with low light levels and, as such, the system processing alters the rate of first image frames dependent on the current light levels.

    Abstract: An ambient light sensor integrated in a compact fluorescent lamp that, in turn, may include a controller and a radiation source. The ambient light sensor may include a radiation receiver to receive and filter incident radiation to obtain a value of the level of infrared radiation, and an electronic module to determine if the value is above a reference threshold value to enable the controller to switch the state of the radiation source.
