This paper presents a novel radiometric compensation approach that applies a six spectral band projector. Conventional radiometric compensation techniques that applied normal three spectral band projectors suffered from the limited dynamic range of the projectors. To improve the compensation accuracies, we propose to control projected images with the six spectral band projector whose spectral intensity is narrower than normal three spectral band projectors. In particular, we apply the filters of channel separation-based stereo projection to realize the six spectral band projector. We evaluated our approach by projection experiments and confirmed that the compensation accuracy could be improved by the proposed method when comparing with conventional method. In particular, we confirmed that the color difference in CIELAB color space of the proposed method was 54.8 % of that of the conventional method.
