Along with the science and technology updates change rapidly, the cameraresolution is higher and higher requirements to become a reality. In the current field ofcamera,10million pixel camera to become mainstream. Based on the CCD millionpixel camera design, and the vidicon pre exposure technique and automatic electronicshutter, automatic gain technology realization methods are discussed.This paper start to the domestic and foreign research situation of machine visionsystem, and the development direction henceforth made a simple introduction andanalysis. Then described in detail CCD classification, working principle andcharacteristics of CCD parameters, and the CCD and CMOS comparison.CCD KODAK chip design company KAI-11002chip production. The chip is aninterline transfer, progressive scanning large plane array CCD charge coupled device,with electronic shutter, can partially replace the mechanical shutter. And then introducedthe KAI-11002chip basic structure, working principle and the spectral characteristicsand take it as the core and discusses the external timing generating circuit, signalprocessing circuit, a data transmission circuit and power conversion circuit composed ofthe structure and the concrete realization method.FPGA developed by ALTERA company EP2C8T144, the FPGA has a completehardware interface and abundant software resource, to realize the automatic electronicshutter, automatic gain and timing control switch provides a reliable platform. Thispaper discusses the FPGA platform automatic electronic shutter and automatic gaintechnology Verilog HDL implementation methods and gives the main code.Finally, this article on the development of the10million pixel camera was tested,and the test methods and test results are introduced.
