Abstract

This paper is mainly about an image reconstruction algorithm, which based on bayer template. First, to estimate other components´ gradient information through the information of G, according to each component´s gradient correlation, including R, G and B. And then get other component´s values. The bayer image, whose resolution ratio is 1280*1024, 25 frames per second, captured by CMOS, is output by DVI interface or stored in memory after being interpolated and raised frame. The algorithm is verified on FPGA platform. The experiment shows that the reconstruction image´s quality is very high and the PSNR is high to 37 dB.
