A Signal-processing System of Digital Pixel Binning Based on Bi-cubic Filtering Algorithm

摘要

As the development of semiconductor technology, the manufacture process of CCD sensors has been improved continuously. In recent years some new technologies appear on CCD sensors. Analog pixel Binning technology is one of them. In this paper, a new signal-processing system of digital pixel binning based on bi-cubic filtering algorithm is designed. The system overcomes the shortcomings of losing some image details, caused by analog pixel binning which does simply summation of pixel signals. The signal-processing system of digital pixel binning can keep high frequency information through bi-cubic filtering algorithm, which can improve the contrast and MTF of the remote sensing images. This system can achieve pixel binning with lower computational complexity and also it has the good real-time capability for large-scale remote sensing images.
