The Earth's digital elevation which impacts space camera imaging has prepared and imaging has analysed. Based on matching error that TDI CCD integral series request of the speed of image motion  statistical experimental methods-Monte Carlo method is used to calculate the distribution histogram of Earth's elevation in image motion compensated model which includes satellite attitude changes  orbital angular rate changes  latitude  longitude and the orbital inclination changes. And then  elevation information of the earth's surface from SRTM is read. Earth elevation map which produced for aerospace electronic cameras is compressed and spliced. It can get elevation data from flash according to the shooting point of latitude and longitude. If elevation data between two data  the ways of searching data uses linear interpolation. Linear interpolation can better meet the rugged mountains and hills changing requests. At last  the deviant framework and camera controller are used to test the character of deviant angle errors  TDI CCD camera simulation system with the material point corresponding to imaging point model is used to analyze the imaging's MTF and mutual correlation similarity measure  simulation system use adding cumulation which TDI CCD imaging exceeded the corresponding pixel horizontal and vertical offset to simulate camera imaging when stability of satellite attitude changes. This process is practicality. It can effectively control the camera memory space  and meet a very good precision TDI CCD camera in the request matches the speed of image motion and imaging. 2010 SPIE.

A configurable  record capacity extensible and nonuniformity reducible of high speed camera is designed in this paper. The CMOS image sensor lupa-300 which is produced by Cypress Corporation is used for the system. There is nonuniformity existed in the sensor. The two point method of the image with real time correction algorithm has applied to process the image nonuniformity. Then the corrected image is storied into the NandFlash array. To improve the record speed and extend record capacity  the pipelining and parallel bus mechanism is adopted. The experiment which is based on hardware platform indicates the camera can take about 250f/s at a resolution of 640*480  the consistent storage speed is up to 614.4 Mb/s  consistent transmit from flash to Camera Link speed up to 1.093Gb/s.The system record time is up to 18.6 minutes. 2009 IEEE.
