Abstract: A method for characterizing an optical focusing defect of an image capture instrument is based on contrast values. Said contrast values are calculated for two images of a same scene portion, captured in respective overlapping length segments of two image sensors. To this end, the sensors are mounted in an image capture instrument so that the overlapping length segments between the sensors are situated at different heights along a focusing direction perpendicular to said sensors.

Abstract: A method for stabilizing a line of sight of an imaging system on board a satellite uses windows selected within an image sensor. Variations of the line of sight can be characterized at a frequency that is greater than that of a sequential mode of image acquisition by the sensor. The stabilization method can be implemented at the same time as the full-frame acquisition of images by means of the imaging system.
Abstract translation: 用于稳定卫星上的成像系统的视线的方法使用在图像传感器内选择的窗口。 视线的变化可以以比传感器的顺序图像采集模式更大的频率来表征。 稳定方法可以通过成像系统与图像的全帧采集同时实现。
