Image processing system

Abstract

An image processing system is used for dentistry. Upon creating a false tooth of a patient ( 59 ), a plurality of illuminating light of LEDs with different wavelengths emit light and a photographing apparatus ( 1 A) photographs a tooth portion of the patient ( 59 ), thereby obtaining image data. The image data is sent to a dentistry filing system ( 2 A) serving as a processing apparatus, and color reproducing data is obtained by calculation. The color reproducing data is sent to a dentistry factory ( 55 ) via a public line. Data is searched from a database ( 56 ) for calculating a ceramic compounding ratio, compound data of the ceramic false tooth is obtained, matching the color of the tooth portion of the patient ( 59 ), and the false tooth approximate to the tooth color of the patient ( 59 ) is created.
