A new imaging system is designed by using an interline transfer CCD ICX415AL as sensor which is produced by Sony corporation and greatly improve the SNR of system . CCD imaging system uses special signal processing chip-CXA1310AQ making output signal to meet the standard of PAL/CCIR. It can be used with TV and computer which has video card as a display terminal. On the basis of introducing the structure and characteristics of CCD ICX415AL

the circuits of timing sequence and driver for sensor were designed. CCD works in field readout mode which can be realized as binning-technology in vertical direction and the noises of video signal are filtered by Correlated Double Sampling (CDS)

the signal-to-noise ratio of system was enhanced. The system takes Field Programmable Gate Array (FPGA) as the key device. The CCD driving clock

clock control of data acquisition and video signal process were accomplished by the module design method from top to bottom.
