Description

Technical Field

[0001] The utility model relates to the technical field of oral digital viewers, in particular to an oral digital viewer supporting automatic rotation. Background Art

[0002] In clinical practice, dentists insert the camera portion of a digital oral viewer into the patient's mouth, adjust the angle and position based on the area being examined, and press the corresponding button to start taking photos or recording videos. Once the examination is complete, the captured images and video data can be saved to the software for subsequent review, analysis, or sharing with the patient. However, because digital oral viewers cannot automatically distinguish between landscape and portrait orientations, dentists must manually adjust the image through the software each time to ensure it is displayed in the correct orientation. This can lead to operational errors and compromise the dentist's work efficiency and accuracy. Utility Model Content
