In this study, real-time multi-band imaging systems using active illuminants were realized. We constructed the systems for solving essential problems in conventional spectrometers such as spectroradiometers and colorimeters, and pioneered several effective applicable fields. Actually, we developed a synchronous system using a programmable light source and a monochrome camera. Then, we devised a calibration algorithm for controlling the system, and estimation algorithm of surface spectral reflectance. As practicable applications, we realized (1) visual evaluation system under arbitrary illuminant, (2) tristimulus imager, (3) XYZ display.
