In this project, we measured the camera sensor spectral sensitivity. The approach we used here showes that we can achieve the same results with a less number of selected samples to characterize digital camera's sensor spectral sensitivity. This will save us a lot of measurement work.

For the color printer, we established a tetrahedral interpolation lookup table for the transformation from device-independent color space CIELAB to printer CMY space.

As a whole, our camera-printer system is going to reproduce the color taken by the camera. This means that we need to find a proper CMY values for each camera output RGB values so that the printed color and color taken by the camera look as similar as possible. In our system this is done by the following: First convert the camera RGB output of a given color into its CIELAB values. To reproduce this color with printer, we use the established tetrahedral interpolation lookup table to find its corresponding CMY. Through this process, we can make the CIELAB E between the given color and the printed color small(under the same illumination).
