抄録(英) | Previous papers about Random Telegraph Signal (RTS) noise mainly focus on its characteristics in time domain or its Power Spectra Density , which means almost all the researchers devote to the behavior of a RTS noise in a single pixel. Little attention has been paid to how RTS noise distributes on a CMOS Image Sensor Array (CIS) and how its distribution influences the quality of videos produced by that CIS. In this paper, two main works are introduced. One is that the exposure process of a camera is simulated, in which Gaussian noise and RTS noise on pinned-photodiode CMOS pixels are modeled on spatial domain; the other is that a new video quality evaluation method for RTS noise is proposed. Conclusions on how the spatial distribution of RTS noise affects the quality of motion picture will be drawn finally. |
