The camera can be a useful tool to capture images for use in colorimeter. However the RGB signals generated by different camera are not equal for the same scene. The camera for use in colorimeter is characterized based on the CIE standard colorimetric observer. One method of deriving a colorimetric characterization matrix between camera RGB output signals and CIE XYZ tristimulus values is least squares polynomial modeling. However it needs tedious experiments to obtain camera transfer matrix under various white balance point for the same camera. In this paper, a new method to obtain camera transfer matrix under different white balance by using 3x3 camera transfer matrix under a certain white balance point is proposed. According to the proposed method, camera transfer matrix under any other white balance could be obtained by using colorimetric coordinates of phosphor primaries derived from 3x3 linear transfer matrix under the certain white balance point. In experimental results, we confirmed that the proposed method allow 3x3 linear transfer matrix under any other white balance having a reasonable degree of accuracy compared with the transfer matrix obtained by conventional method. |
