Motion restoration of long time exposed images with satellite-borne cameras

Two main different processes for motion restoration in satellite cameras were examined and compared, with regard to obtainable image quality, e.g., signal/signal to noise ratio and resolution, and hardware expenditure. Linear models were used for camera components and long time exposure for mobile objects. It is shown that motion compensation is a simple process for motion restoration. Long time exposure is resolved in many short time exposed single images which are accumulated in a digital memory. Another process, image restoration, is used only for restoration of motion distortion inferior to two picture points. A comparison of expenditure is given for both processes.
