This paper proposes a method for precise multi-spectral rendering based on multi-spectral image compression. Firstly, in order to improve multi-spectral rendering resolution, we develop a data compression algorithm suitable for multi-spectral image. The spectral distribution data is normally represented in a high dimensional vector by sampling the visible wavelength range 400-700nm. The spectral distribution data need much more memory capacity than RGB data for recording and rendering of objects as digital images. Secondly, the rendering method with the data compression algorithm is implemented to Graphics Processing Unit(GPU) for improving resolution and performance. Finally, the validity and accuracy of proposed method is confirmed by rendering image using compressed multi-spectral distribution data.
