Abstract: In the image acquisition process in space applications, the image signal may undergo all kinds of noise signal interferences to greatly impair the visual effect of the image. For a data processing system with a high requirement of real time operation, it is time-consuming to realize pre-denoising with software. In this paper, a specified novel modelized IC based on FPGA is designed to realize the image acquisition and denoising. Experimenal and simulation tests show that the desirable results can be achieved.
