1. A photosensor array of pixels each of the pixels comprising: a current generating photodetector having a photodiode that is operatively coupled in combination with an associated multiplying current mirror located within the pixel and comprised of one input transistor and at least two output transistors where the generated photocurrent from each photodetector is multiplied by an integer equal to the number of output transistors in the associated multiplying current mirror and to provide the multiplied current as an output signal; and wherein the output signal is selectively switched through a plurality of amplifiers having positive gain during periods where the photosensor is receiving incident light and negative gain during periods where the photosensor is not receiving incident light.
