ABSTRACT:
Sensor correction circuit for maintaining offset voltages in the shift registers of a multiple channel image sensor substantially equal having a pair of control gates to permit sampling the current offset voltages in the shift registers of each channel, a pair of capacitors for storing the offset voltage samples in each channel; a clock for actuating the control gates in preset timed relation between scan lines to sample and store the current shift register offset voltages on the capacitors; and an amplifier for amplifying any difference between the offset voltage samples held by the capacitors to provide an adjusted potential for balancing any differences between the shift registers.
