Design of planar array CCD Imaging System Based on FPGA

A novel CCD imaging system is designed by adopting interline transfer planar array CCD ICX415AL made by SONY as an imaging sensor,and taking FPGA chip EP1C12F256 made by Altera as CCD timing generator to drive signal.In the system,the correlated double sampling technology is adopted to eliminate the related noise in video signals to improve SNR,VHDL programming is used in the development environment of Quartus II 9.1 and Modelsim SE 6.5 is employed to carry out simulation.The experimental results demonstrate that the designed time sequence can meet the demand of ICX415AL and outputs 50 frames per second under 29.5 MHz clock-driven.
