マルチバンド画像入力システムの開発 : 拡張RGB色空間入力システムへの応用

概要

A highly accurate multispectral camera and the application software have been developed as a suitable system to capture digital images of the artworks stored in galleries and museums. Instead of recording color data in the conventional three RGB primary colors, the newly developed camera and the software carry out a pixel-wise estimation of spectral reflectance, the color data specific to the object, between the wavelength range of 380 [nm]and 780 [nm] to enable the practical multispectral imaging. In order to realize the multispectral imaging, the dynamic range of the camera is set to 14 bits or over and the output bits to 14 bits so as to allow capturing even when the difference in light quantity between the each channel is large. Further, a small-size rotary color filter was simultaneously developed to keep the camera to a practical size. This camera can apply extended RGB color space to capturing system.
