Abstract：According to the displaying problem of the high radiation resolution remote sensing image(HRRRSI) in ordinary equipment, this paper presents a suitable new algorithm for the displaying of the HRRRSI. This algorithm based on image high radiation resolution large gradient field gradient attenuation can be used to accurately display the detailed information of HRRRSI on common display device. The technical route of this algorithm is as follows: Firstly, the brightness dynamic range of the true HRRRSI is compressed. Then,the compressed remote sensing image is reconstructed to get low dynamic domain image. Finally,through a comparison with the commonly used linear stretching processing results, the effectiveness of this algorithm is varified. The results show that the algorithm can achieve considerable dynamic range compression of HRRRSI and can also reserve the details of the image information and inhibit general edge effect.
