CCD驱动系统作为航空数码相机的关键组件,直接关系到航空数码相机成像的质量。介绍了利用CCD专用外围芯片组来完成CCD外围电路的设计,并详细讨论了利用该芯片组设计大面阵CCD图像传感器外围电路时要注意的一些问题。从图像的质量和图像中出现的问题出发,来指导CCD驱动电路系统的设计,指出驱动电路设计和图像质量的相互影响关系,为高质量航空数码相机的研制提供一些借鉴。
CCD drive system as a digital camera components of aviation, is directly related to the quality of aerial digital camera imaging. This paper introduces the design of peripheral circuit of CCD by using CCD peripheral chip, and discusses some problems that should be noticed when using this chipset to design peripheral circuits of large area CCD image sensor. From the quality of the image and the problems in the image, this paper will guide the design of the CCD drive circuit system, point out the interaction between the design of the drive circuit and the image quality, and provide some references for the development of high quality digital cameras.
