Abstract
AN IMAGE SENSOR (10, 11) THAT HAS A PLURALITY OF PIXELS (14, 14’) WITHIN A PIXEL ARRAY (12) COUPLED TO A CONTROL CIRCUIT AND TO ONE OR MORE SUBTRACTION CIRCUITS. THE CONTROL CIRCUIT MAY CAUSE AN OUTPUT TRANSISTOR (116) COUPLED TO A PIXEL TO PROVIDE A FIRST REFERENCE OUTPUT SIGNAL, A COMMON RESET OUTPUT SIGNAL, AND A FIRST SENSE-NODE RESET OUTPUT SIGNAL, BETWEEN WHICH A SUBTRACTION CIRCUIT MAY FORM A WEIGHTED DIFFERENCE TO CREATE A NOISE SIGNAL. THE CONTROL CIRCUIT MAY CAUSE THE OUTPUT TRANSISTOR TO PROVIDE A SECOND SENSE-NODE RESET OUTPUT SIGNAL, A LIGHT RESPONSE OUTPUT SIGNAL AND A SECOND REFERENCE OUTPUT SIGNAL, BETWEEN WHICH A SUBTRACTION CIRCUIT MAY FORM A WEIGHTED DIFFERENCE TO CREATE A NORMALIZED LIGHT RESPONSE SIGNAL. THE LIGHT RESPONSE OUTPUT SIGNAL CORRESPONDS TO THE IMAGE THAT IS TO BE CAPTURED BY THE SENSOR. THE NOISE SIGNAL MAY BE SUBTRACTED FROM THE NORMALIZED LIGHT RESPONSE SIGNAL TO GENERATE A DE- NOISED SIGNAL.
