| Abstract: | The visible camera plays an important role in space security area,which has high resolution,high definitionand high quality image. Based on the characteristics of CMV4000 detector, the paper introduces the color interpolation and white balance methods, which reconstructs color image.Through comparison and analysis, gradient-based interpolation algorithm and gray world method are availability for color data reconstruction.The results show that the gradient-based interpolation and the white balance method can effectively restore the color image, which can acquire high quality color image in space environment. |
