%X By analyzing the data of state produced hyperspectral resolution imagining spectrometer OMIS I system, it was found that the same field spectral curves of the edge and center parts of the images were changed showed because of the effects of bi directional reflectance distribution and the bigger scanners (Field of View FOV). The same field features showed different color on color synthesis images. By analyzing a lot of data, a histogram match method was developed for fitting spatial parameter. All of the procedures were carried out in the VC++program. The research result shows that the brightness of the images calibrated by this method have been enhanced greatly.
