Noise suppression method, named AGI (Alternated Gain Inversion), is studied for realizing a highly sensitive high definition CCD image sensor. The sensor is a high photoconversion ratio STACK CCD imager. 1/5 noise suppression by the AGI is expected from the spectra analysis. Actually, the drastical noise reduction has been realized using the 1" 2M pixel STACK CCD imager.
