The commercial CCD device has been encapsulated the sensor driver inside which is not opened for secondary development. Even this mode facilitates the usage but it really cannot content the customizable need. For solving this challenging but imperative issue, we designed a novel CCD sensor driver system which implements the efficient and effective image acquisition task in customizing approach. The working principle and driving timing sequence about ICX625AQA the interline CCD image sensor used in our system are discussed in detail.For handling with this data intensive task, a high performance Field Programmable GateArray (FPGA) controller is used for data allocation and translation, the peripheral circuits including AD9974 and CXD3400 drive interface which process the horizontal signal and vertical signal, respectively. The designed system proposed at the end of this paper. Keywords Interline Transfer; Field Programmable Gate Array(FPGA); Dual-channel Output; Charge Coupled Device(CCD) Introduction Charge-coupled device(CCD) has many excellent features, such as high sensitivity, large dynamic range, low noise, low power consumption and fast sampling speed. The CCD sensor is such a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated [1] .CCD image sensor converts optical signal into charge signal by an optical -sensitive surface,and then according with certain rules to output image based on corresponding pulse timing driver.CCD image sensor has better performances in optical filling rate, the uniformity of the response of pixels and quantum efficiency than CMOS and become a science of choice detector for high frame rate imaging acquisition system increasingly [2] , The array CCD image sensors can be implemented in several different architectures. The most commonarchitectures are full-frame, frame-transfer, and interline. Each of these architectures has its different approach to the problem of shuttering. The interline transfer because of its advantages and fast readout speed CCD camera has been used in high frequency [3] . The mainly driving circuit of interline transfer CCD includes biased voltage circuit, the horizontal timing-driven circuit and vertical timing-driven circuit.In such circuits mentioned above, the first encountered issue is how to generate theCCD drive timing. In generally, there are four different methods to deal with this challenging matter: direct digital circuits, microcontroller-driven, EPROM-driven and programmable logic devices method [4] . Programmable logic devices such as field programmable gate array (FPGA) includes many advantages such as the ability to re-program in the field to fix bugs, can be repeated or improved after completing the design and easy to update and maintenance.Thus characteristics make the FPGA graduallydominates the application for CCD sensor driver and. The driver circuits implemented based FPGA is higher integration, reliability and performance, lower power consumption,cheaper price cost and shorter development cycles period [5] . In this paper, we focus on how to design a novel CCD sensor driver system which implements the efficient and effective image acquisition task in customizing approach based on FPGA. Firstly, we discuss the parameters and work principlesaboutICX625AQA, one of the typical CCD sensors. Secondly, we describe the design of hardware driving circuit including horizontal drive,vertical drive and voltage generation circuitas well as illustrate the circuit layout and manufacture board. Thirdly, we proposed the final board about the system. Finally,we conclude our work and prospectthe further tasks.
