AI Technical Summary

Technical Problem

Existing tooth alignment image generation devices cause discomfort due to inaccurate color representation of teeth and dental plaque, especially when using blue light excitation, which results in low reproducibility of color tones.

Method used

A tooth alignment image generation device that acquires images of teeth and dental plaque irradiated with blue light, performs white balance processing on partial images to adjust color tones, and synthesizes these images to generate a tooth alignment image with improved color accuracy and reduced discomfort.

Benefits of technology

The solution effectively reduces discomfort by adjusting the white balance of partial images to align with actual color tones, enhancing the clarity of tooth outlines and simplifying the image synthesis process, resulting in a more comfortable and accurate dental image generation experience.

Abstract

This dentition image generation device comprises: an acquisition unit (51) that acquires captured images obtained by imaging dental plaque and the surface of a dentition in an oral cavity irradiated with light including a wavelength region of blue light; a processing unit (52) that performs white balance processing on each of a plurality of first dentition block images that are partial dentition images based on the captured images and thereby generates a plurality of second dentition block images; and a synthesis unit (53) that synthesizes the plurality of second dentition block images to generate a dentition image.
