Design Of Color High Resolution CCD Imaging System Based On FPGA

In recent years,with the development of photoelectric technology,CCD color camera can get more image data,better recognition of the target.New CCD image sensor has small size,high sensitivity,high resolution,image distortion,no residual image,impact resistance,shock resistance,anti electromagnetic interference,can work for a long time in bad environment,using many of the advantages of long service life,easy to deal with information,and microcomputer interface and convenient,and compared to CMOS image sensor,CCD image sensor in terms of sensitivity,resolution,noise control has obvious advantages.With the increase of spatial and temporal resolution,you can get more of the color image information,in order to meet the image acquisition system of color image signal of high resolution sampling and real-time requirements of the output image,you need special design of CCD acquisition system.The strong function of the FPGA,the CCD driving circuit,signal processing circuit and display drive integrated circuit on a FPGA chip to achieve CCD image system is miniaturization,intelligent and integrated.Because of its strong anti-interference,easy to realize the automatic control system interface,can be designed into high sensitivity,high precision real-time online acquisition system.In order to obtain more information to be collected,the realization of real-time image acquisition and processing display.System uses the AHB chip bus architecture design,all data transmission needs to be carried out on the bus,using the overall method can improve the efficiency of data transmission.The from the working principle of CCD of the color CCD camera circuit part of an in-depth research,selection of Sony's icx285 aq type color CCD as image sensor,ffga of CCD driving timing generation and output signal processing methods of integration design based on,and with the AHB bus interface,the detectability for the future development of high performance in application in space detection field of high-definition color video system to lay a foundation for the theory and practice.
