The simulation of CCD imaging process is an important base for achieving the micromation and intelligence of CCD imaging system.The signal processing of CCD imaging system,which includes AGC(Automatic Gain Control),gamma correction and BLC(Backlight Compensation),is analyzed.Then,the method of simulation and parameter optimization in CCD imaging signal process is discussed.To evaluate the validity of the proposed simulation methods,software based on the proposed model and algorithm is designed.The experiment results show the effectiveness of the proposed method in the simulation and parameter optimization of CCD signal process.
