PURPOSE:To raise a reliability by executing an image pickup of a state of peeling-off of a paint of a tooth surface or a transfer by a video camera, and executing a decision of success or failure, or a grade from a value obtained by executing an operation processing as picture information. CONSTITUTION:First of all, indexing of a tooth surface of a test gear 1 is executed by a proximity switch 14, and a timing of insertion of a picture by a TV camera 9 is obtained. Subsequently, the TV camera 9 executes an image pickup of the tooth surface by this timing. This video signal is converted to a digital signal by an A/D converter 10 by setting a suitable threshold level, and picture information is stored in a picture memory 11. Next, after a stopgap processing, a decision of tooth bearing is executed by a microcomputer 12, and if it is successful, a blue pilot lamp 15 is lighted, and if it is unsuccessful, a red pilot lamp 16 is displayed. |
