The Prototype of Real-Time Image Pre-Processing System for Satellites' Remote Sensing

Abstract

high resolution image combination and processing plays an important role in today's satellites' remote sensing applications. This paper presents an image recombination and processing system for one-dimensional multi-strip CMOS image sensors (CISs.) The proposed system takes advantage of the satellites' linear moving property to control the exposure time of CIS and provides the real-time ability to generate 11,200 x N high-resolution image for satellites' remote sensing applications. The details of hardware design to meet real-time requirement are given out. The prototype, which contains four strip CISs, is implemented to verify functionality and capability of real-time image acquisition and combination. The implementation results show the proposed system, which demands four times larger throughput than the prototype, is feasible in a chip.
