The spectral sensitivity of a CCD camera is a prominent electro-optical characteristic for color image formation. In this paper, spectral estimation of color CCD cameras generally involves the assessment of overall spectral sensitivities, which are composed of those of optics, filters, and CCD sensors. To this end, we develop an automatic testing/measurement system with an optical platform. And, the spectral characterization of a CCD camera imaging process is presented in the approach of vector representation for the estimation problem. This technique examines the modulated incident colored lights, which are regarded as a set of color stimuli candidates, to be the effective color stimuli, such that they can be successfully applied to generic estimation algorithms. To show the feasibility of this work, a realization of a basic set of color stimuli candidates is generated in the numerical and graphical forms. In our approach the use of a spectrophotometer is needed only for the system calibration. It would be pleasing that this technique will practically simplify the complexity of the spectral estimation problem of CCD cameras.
