| Abstract: | Based on the working principle of liD CCD imaging sensor and AD9847 video processing chip, HD video signal processing circuit is designed. With FPGA（Field-Programmable Gate Array） chosen as the hardware design platform, initialization set and driving schedule generator of AD9847 are described by using VHDL. The function simulation of the system is successfully fulfilled with ISE10.1 software and the simulation results show that the developed HD CCD video signal processing circuit can not only meet the requirements of HD CCD imaging system, but also have reliable performance and functional agility. |
