摘要	In order to increase the dynamic range of push-broom remote sensing cameras, An imaging method which applied the DTDI (Digital domain Time Delay Integration) technology with fixed integral stages and display method of HDR (High Dynamic Range) image was investigated in this paper. Firstly, the principle of DTDI was introduced. Secondly, by adopting the DTDI technology with fixed integral stage, the full well limitation could be overcome. Thus, a picture with higher image bit depth and larger dynamic range could be achieved, and then the dynamic range of the push-broom remote sensing camera got extended. Finally, a new evaluation function based on the entropy and histogram of an image was constructed, and it could be used for automatically selecting the best show window covering the most abundant information and the richest gradation from the original HDR image. The calculation and experimental results indicate that when the fixed integration stage is 64, the dynamic range of the push-broom remote sensing camera increases by 36.124 dB. And the automatic selection by the constructed evaluation function can get the best result more accurately and quickly than the artificial selection. The method proposed in this paper can meet the demands of HDR imaging and display in the field of push-broom remote sensing cameras. 2018, Science Press. All right reserved.
