%X For the CCD-camera system,its resolution is mainly decided by the size of CCD-pixels and the pixel number of a single CCD chip. To improve the resolution,multi-CCD assembly technique is used. In this application,variation of illuminance is a factor affecting the system precision,and is also make it difficult to decide the threshold of image binarization. We calculate the illuminance of a 4-CCD assembly camera with the resolution 27. 61p/mm in this paper. Two methods to compensate it is advanced and discussed here.
