Abstract
PURPOSE:To automatically replace an adjacent tooth with a color sample, by comparing the color image of the adjacent tooth with the numerical hue data of a preliminarily stored color sample to select a color sample min. in color difference. CONSTITUTION:The adjacent tooth of a tooth to be treated is photographed under a definite illumination condition by a color camera 11 to be displayed on the picture of a color CRT 12. Next, the hue data at the arbitrary point of the color image displayed on the color CRT 12 is handled as a numerical value and the color sample of the teeth min. in the inputted color difference with the teeth in the oral cavity is automatically selected. At this time, color comparison may be performed in an RGB color system and said hue data may be converted to other color system such as an XYZ color system to automatically select a shade guide becoming min. in color difference. By this method, the color data of the adjacent tooth 17 and a floppy disk 13 having the number selection data of the shade guide stored therein are regenerated on the picture of the color CRT 12 and an artificial tooth is prepared after this image.
