Paper Abstract

Image sensors are important components of lunar exploration device. Considering volume and cost, image sensors generally adopt a single CCD or CMOS at the present time, and the surface of the sensor is covered with a layer of color filter array(CFA), which is usually Bayer CFA. In the Bayer CFA, each pixel can only get one of tricolor, so it is necessary to carry out color interpolation in order to get the full color image. An improved Bayer image interpolation method is presented, which is novel, practical, and also easy to be realized. The results of experiments to prove the effect of the interpolation are shown. Comparing with classic methods, this method can find edge of image more accurately, reduce the saw tooth phenomenon in the edge area, and keep the image smooth in other area. This method is applied successfully in a certain exploration imaging system.
