MULTI-SPECTRUM IMAGE PROCESSING APPARATUS AND COLOR REPRODUCTION SYSTEM EMPLOYING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a multi-spectrum image processing apparatus and color reproduction system in which a multi-spectrum image is converted into image data with high compatibility with an existent three-band system. PSOLUTION: A multi-spectrum image processing apparatus comprises: a base image converting means 6 for developing an inputted subject multi-band image on the basis of a base vector and converting the image into a base image; a base vector calculating means 2 for calculating said base vector; and an output means 7 for outputting a multi-spectrum image based on the base image converted by the base image converting means 6, wherein the base vector calculating means 2 is characterized in calculating, as a base vector, a base vector for three primary colors determined by a product of a predetermined rendering illumination spectrum and a color matching function and an orthogonal base vector, being orthogonal with the base vector for three primary colors, based on statistic information of spectral reflectance of a subject.
