    Abstract: An optical sensor includes an infra red LED, a photodetector and a lock in charge amplifier. The photodetector passes charge to a feedback capacitor of the charge amplifier following an illumination cycle during which the LED is emitting and also following an illumination cycle during which the LED does not emit. An amplifier presents an output indicative of the difference between the charge generated at the photodetector during the illuminated and non-illuminated cycles.

    Abstract: An imaging system is disclosed comprising a plurality of pixels; a pixel readout means for producing a plurality of first image frames; a image output means for producing a plurality of second image frames and operable to produce a second image frame from more than one of the first image frames, wherein the pixel readout means is enabled to produce the first images frames at a rate faster than the image output means produces the second image frames. Through combining first image frames, by averaging or other statistical combinations, the photon shot noise of second image frames can be reduced. Photon shot noise affects images with high light levels more than those with low light levels and, as such, the invention also discloses altering the rate of first image frames dependent on the current light levels.

    Abstract: An optical navigation device includes a navigation radiation source capable of producing a beam of radiation, and an optical element. The optical navigation device is for identifying movement of an object to thereby enable a control action to be carried out. A sensor is for receiving an image based upon reflected radiation from the navigation radiation source, and at least one illumination radiation source is for illuminating the optical navigation device. The device is operable, in recurrent cycles of at least reset, expose, and readout phases, to activate the at least one illumination radiation source during the reset phase. The reset phase may have the longest duration of the phases.
