Abstract : An image system is constructed with a PC computer by using IL2E2 TDI CCD sensor. The images are displayed in the CRT of the computer. The design to the timing generator of a high speed CCD camera is mainly described by using FPGA. The hardware description to the timing generator circuits is realized by using the AHDL language. The simulation to the timing generator circuits is made by using Max Plus2 software. Finally ,
after programming a FPGA chip and making the experiment of the circuits , the control of a CCD camera is real2 ized.
