摘要	In order to design a charge-coupled device (CCD) driving circuit with a high frame rate and a large area array which can support the electronic image motion compensation function, first a basic driving circuit of the large-array CCD is reported in this paper. Next, electronic image motion compensation is realized by adding an image motion compensation timing generator and a main timing generator, Saa8103. The internal design structure of the image motion compensation generator is provided and is characterized as follows. The data are first sent by the system controller, the main timing generator and the image motion compensation timing generator. The generator, the vertical driver, the horizontal driver and the full-frame charge-coupled device chip are then composed. During the exposure period, the image motion compensation transfer clock is generated by the image motion compensation timing generator, and the charge-coupled device charge packet is driven to track the image movement after being amplified by the vertical and horizontal drivers to carry out electronic image motion compensation in the vertical direction. During the output period, the vertical and horizontal rotations generated by the main timing generator are carried out by the image motion compensation timing generator. The shift clock is transmitted to the vertical and horizontal drivers to drive the charge-coupled device to produce the output. The phase relationship of the four corners of the charge-coupled device is independently controlled by the image motion compensation timing generator, which supports not only the electronic image motion compensation but also the flexible selection of the output channel number and output mode. A field-programable gate array (FPGA)/complex programable logic device (CPLD) has been selected to be the timing generator of image motion compensation, and timing simulation is carried out. Lastly, the design of the driving circuit was verified by an indoor image motion compensation experiment, and a good compensation effect has been achieved. In this system, the charge-coupled device adopts a separate driving technology, and the charge transfer direction of each block can be established. Consequently, it is convenient to select the number of output channels and the output mode, which makes the camera suitable for different occasions, supports the charge-coupled device in terms of the output and electronic image motion compensation in various ways, and is capable of generating full-frame images. In order to meet the different requirements regarding the charge-coupled device frame frequency in different contexts, this proposed design overcomes the disadvantages of the complex structure and low reliability of traditional optical mechanical image motion compensation systems.
