1. An electronic light processing cell comprising: a photo sensor unit provides an analog electrical output proportional to an amount of light impinging on the photo sensor; a noise source provides a noise output; a comparator compares, during a plurality of times during a frame of an image, the analog electrical output and the noise output and provides a binary digital output representative of each comparison; a digital counter counts the binary digital outputs during the frame and stores a count at the end of a frame where the value of the stored count is proportional the light impinging the photo sensor, the value of the stored count adapted for use by an image processing unit to render an image based on a plurality of such values representing different locations within the frame.
