2色分解信号からのカラー画像の分光推定

概要

We show color image rendition from 2-color separation signals. A spectral estimation algorithm is discussed in detail, where a spectral distribution is restored from 2-color separation signals by solving a Wiener inverse eguation. Color reproducibility is analyzed using a sinusoidal SPD technique. Various combinations of 2-color separation optics are simulated and the choice of color channels is discussed in relation to the experiments. Findings show that a red primary is most important in the subjective color renditions and a combination of red and green channels is the best choice for 2-color separation optics. Although the lacking pure primary colors could not be restored well, the proposed algorithm would be applied for quasi-true or pseudo-color renditions rather for than correct true color renditions.
