Title: METHOD FOR REDUCING THE ERROR INDUCED IN PROJECTIVE IMAGE-SENSOR MEASUREMENTS BY PIXEL OUTPUT CONTROL SIGNALS
Abstract:
An image sensor for forming projective measurements includes a pixel-array wherein each pixel is coupled with conductors of a pixel output control bus and with a pair of conductors of a pixel output bus. In certain pixels, the pattern of coupling to the pixel output bus is reversed, thereby beneficially de-correlating the image noise induced by pixel output control signals from vectors of the projective basis.
