Abstract

A procedure for the definition of optimum spectral transmission curves for any solid-state (especially silicon-based CCD) color camera is presented. The design of the target curves is based on computer simulation of the camera system and on the use of test colors with known spectral reflectances. Color errors are measured in a uniform color space (CIELUV) and by application of the Commission Internationale de l’Eclairage color difference formula. Dielectric filter stacks were designed by simulated thermal annealing, and a stripe filter pattern was fabricated with transmission properties close to the specifications. Optimization of the color transformation minimizes the residual average color error and an average color error of ~ 1 just noticeable difference should be feasible. This means that color differences on a side-to-side comparison of original and reproduced color are practically imperceptible. In addition, electrical cross talk within the solid-state imager can be compensated by adapting the color matrixing coefficients. The theoretical findings of this work were employed for the design and fabrication of a high-resolution digital CCD color camera with high calorimetric accuracy.
