Description

Dental Image Display Apparatus and Method The present invention relates to a dental image display device and a control method thereof. Generally, dentists observe the inside of the oral cavity visually or using an oral camera to diagnose the oral health, including the teeth and gums. At this time, the oral images captured by the oral camera can be viewed on a computer using software typically called a viewer. At this time, in oral images, dental caries, tartar, and cracks in the teeth and gums may be depicted differently depending on the type of light source used during imaging. For example, if an infrared light source is used, areas of dental caries and cracks appear dark, which is advantageous for identifying dental caries and cracks, and if an ultraviolet light source is used, areas of dental caries or tartar appear red, which is advantageous for identifying dental caries and tartar. Therefore, during dental diagnosis, different light sources may be used depending on the preference and proficiency of the medical staff or the patient's condition, and the medical staff may display and verify heterogeneous images captured using light sources of different wavelengths together or display them alternately depending on the situation. However, when attempting to examine different images for each specific region within the oral cavity, displaying heterogeneous images together or cross-referencing them is somewhat cumbersome and may reduce diagnostic accuracy. The technology forming the background of the present invention is disclosed in Korean Published Patent Application No. 10-2018-0030285.
