The integration-type indistinctness degree glossiness for curved surfaces was newly introduced, so the measuring was stabilized and the automatization of the measuring was also rialized.

The pearl color sorting system was miniaturized using a CCD-TV camera which provides the R, G and B color signals, compared with the previously reported system with the MOS-TV camera and the TV monitor.

The measuring error in the measurement of the glossiness of curved surfaces was significantly reduced by two techniques; change of the setting of the CCD line sensor and scanning of specimens.
