In consideration of the absence of blue band of"ZY-1"02C satellite, this paper selects a suitable linear band calculation model to achieve its true color synthesis and further enhances the true color of vegetation display of the image through a method of weighting by green band and near-infrared band on the basis of present simulating true color technology. Experimental results show that reconstructing blue band in the way of weighting method model produces the best display effect of natural color; moreover, the green band and near-infrared band are weighted under the limit of NDVI, which not only enhances the display effect of vegetation but avoids the color variation of non-vegetation areas such as buildings, water bodies and bare land.
