Abstract (in Japanese) (See Japanese page) 
(in English) We are aiming at realizing the ultra-high sensitivity camera with an F-number less than 1, which is hard to implement in a single-aperture optical system. In this study, we study applicability of a photon-counting-level ultra-low-noise CMOS image sensor. CMOS image sensors have an in-pixel amplifier for each pixel. Therefore, the noise level differs pixel by pixel. Moreover, extremely large noise called random telegraph signal (RTS) noise appear at not a few pixels. In the simulation, the noise performance in 3 × 3 aperture system using real read noise data is investigated with the read noise data measured by a prototype ultra-low-noise CMOS image sensor. In the raw image, the effective noise of the pixel which has RTS noise is 6.47 e-RMS. After simple averaging, effective noise becomes 0.80 e-RMS. With the proposed selective averaging method which minimizes synthetic sensor noise, the effective noise becomes 0.18 e-RMS and RTS noise is removed.
