Abstract: CCD Sensor is the crucial equipment for environment perception which is widely used in various fields such as surveillance, vision navigation and machine vision. 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 canít 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 Gate Array (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 system execute code is compiled and configured in the Quartues II IDE and is simulated used the SignalTap. Some significant results also are proposed at the end of this paper.

 

Keywords: Interline transfer, Field programmable gate array (FPGA), Dual-channel output, Charge coupled device (CCD), ICX625AQA.
