Optimization of Spectral Sensitivities of a Color Image Acquisition Device Based on a Colorimetric Evaluation Model and a Color Image Acquisition

Abstract

Optimization of spectral sensitivities of a set of color sensor is very important to acquire colorimetric information of object being imaged. In the present paper, for the technical tractability, the problem on the design of an optimal set of spectral sensitivities with Gaussian distribution functions is addressed based on a colorimetric evaluation model. It is shown that the shapes of the optimal spectral sensitivities sharpen and the peak wavelengths tend to locate at equal intervals with a decrease of signal-to noise ratio (SNR) to suppress the noise effects. The six multispectral camera was assembled using a set of six interference filters based on the optimization and the preliminary experimental results were presented
