To maintain the needed accuracy and reliability for tongue character analysis,a right color reproduction method has to be employed to reduce color distortions.

In some high_precision color reproduction applications, there is a need to obtain spectral reflectance of each point on the object s surface.

The application of Multispectral imaging in color science is to acquire the spectral information of the imaging scene, and consequently high fidelity color reproduction can be achieved.

Analysis to calculation method of color reproduction error is described,and correcting color matrix of correcting color reproduction error is obtained in this paper.
