Because the output signal of infrared CCD is of high background and wide dynamic range,it is essential to eliminate the DC high background and automatic gain for smoothing the background noise as well as extracting target signal in this signal's processing circuit.It introduces some normal methods for the application on this signal procession by analyzing the design requirements of infrared CCD signal.At last,it stresses the integration design method on CCD signal processing circuit based on CPLD and VSP3010.
