The goal of this pager is to describe the key questions on designing the cone diameter detecting system by linear CCD. This paper first describes the detecting scheme. In particular  the factors affecting accuracy  such as resolution  voltage difference between neighbor pixels  detecting rate and so on  are analyzed  and the quantitative estimation equations are provided. CCD takes on the photoelectric translation and measuring component double functions  so the waveform of CCD output signal and the affecting factors merit deep discussion. On the basis of discussion  several principles that can be used to improve the boundary recognition accuracy are presented.
