Abstract

The invention proposes an intraoral imaging system in the mouth with a simplified operational interface. The imaging system comprises an image sensing unit for capturing oral images, a central processing unit for controlling an image capturing program of the image sensing unit, a memory cell, an image processing unit, an image stability definition unit for calculating the proportion of image pixels already tending to be stable in all captured images, an image stability judging unit for comparing the proportion of the image pixels already tending to be stable in all current captured images with a threshold value, and an automatic image acquisition unit. When the proportion of the image pixels already tending to be stable in all current captured images is larger than the threshold value, the automatic image acquisition unit can be driven by the central processing unit to automatically acquire current images. The acquired images are stored in a storage medium or are transmitted to a host computer through a serial transmission interface after being processed by the image processing unit.

Description

technical field [0001] The present invention relates to a photographing system for photographing the interior of the oral cavity. Background technique [0002] Generally speaking, when a dentist checks a patient's teeth, it is necessary to obtain a photo of the patient's oral cavity to assist the dentist in diagnosing the patient's dental disease. Therefore, various intraoral cameras have been developed to assist dentists in diagnosis. However, the current intraoral cameras need to be connected to a host, such as a personal computer (PC), when scanning images, and the static intraoral images need to be obtained through the operation of the host. As a result, the operation of the intraoral camera becomes quite complicated, and the acquisition of intraoral images needs to be completed through a computer host. [0003] Therefore, it is necessary to develop an intraoral photography system that is easy to operate and can acquire intraoral images independently of a host computer...
