| Abstract: | VSP2000, an excellent CCD signal processor, employing some key techniques, such as correlated double sampling (CDS), dummy pixel auto-zero loop and black level auto-zero loop, to process the analog signal with high quality, has been widely used in digital still and mobile cameras, PC cameras and monitor cameras. These techniques and some matters in application are introduced in the paper. |
