Abstract
The specification discloses a technique for suppressing the effect of noise generated during the introduction of a charge into a potential well of a charge coupled device. The technique involves detecting the voltage appearing on a floating diffused region during the introduction of the charge through the floating diffused region into the CCD potential well. An error signal is developed from the detected voltage and is subsequently utilized to extract noise from the output electrical signal of the CCD.
