MULTISPECTRAL IMAGE PROCESSING DEVICE AND COLOR REPRODUCTION SYSTEM USING THE SAME

摘要

A multispectral image processing device of the present invention comprising: a base image conversion unit 6, which expands an input multiband image of a subject based on a base vector to convert it into a base image; a base vector calculation unit 2, which calculates the base vector; and an output unit 7, which outputs a multispectral image based on the base image converted in the base image conversion unit 6 is characterized in that the base vector calculation unit 2 calculates a base vector for 3 primary colors obtained by the product of a predetermined rendering illumination spectrum and a color matching function, and an orthogonal base vector, which is orthogonal to the base vector for 3 primary colors and based on statistical information on the spectral reflectance of the subject as the base vectors. Thereby, a multispectral image is converted into image data highly compatible with an existing 3-band system.
