摘要：
There are two main image sensors that are now being widely used in image capture system: CCD and CMOS imager. The fill-factor of CMOS imager is lower than that of CCD, so it is of great importance to consider the influence of the fill-factor on sub-pixel measurement accuracy. the main purpose of this paper is to give a discussion of sub-pixel measurement accuracy of CMOS imager based on a digital camera which is designed and manufactured by ourselves. Conclusion is presented at the end of this paper, that the sub-pixel measurement accuracy of CMOS imager OV7620 can be 1/6 pixel.
