MULTISPECTRAL IMAGE PROCESSING DEVICE AND COLOR REPRODUCTION SYSTEM USING THE SAME

摘要

A multispectral image processing device includes: a base image conversion unit (6) which spreads an inputted object multiband image according to a base vector and converts 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 by the base image conversion unit (6). The base vector calculation unit (2) calculates as a base vector, a vector for three primary colors obtained by multiplication of a predetermined rendering illumination spectrum by an equal color function and an orthogonal base vector orthogonally intersecting the base vector for the three primary colors and based on the statistical information on the spectrum reflection ratio of the object. Thus, it is possible to convert a multispectral image into image data having a high compatibility with the existing 3-band system.
