Abstract
A method to estimate colorimetric information or spectral information of objects being imaged through a use of color image data is usually used to reproduce colors of the objects faithfully independent on devices and recording illuminants. As stated above, a color image acquisition device has two aspects. In this paper, two simple models are introduced for the evaluation of the devices to capture colorimetric or spectral information, and their optimal spectral sensitivities based on these models are compared. It is shown that the optimal spectral sensitivities to capture the spectral information depend largely on the color image acquisition conditions, such as the spectral reflectances of the objects or the recording illuminants, compared with that of the colorimetric information.
