Abstract: The present disclosure relates to a method for self-investigating an optical element embedded in an intraoral scanner, and a system using the same. The reliability of an intraoral scanner may decrease due to foreign matter attached to an optical element. Accordingly, the present disclosure provides a prescribed method for investigating foreign matter attached to an optical element, and a system using the same, wherein an alarm providing notification of the need to inspect the optical element is generated when it is determined that foreign matter has stained the optical element. According to said investigation method and system, a user of an intraoral scanner can automatically determine the presence or absence of foreign matter when scanning an object (patient's affected area), and thus can service the optical element or replace a part in which the corresponding component is formed. Therefore, there is an advantage of improving the scanning efficiency and data reliability of the intraoral scanner.

Abstract: An image processing apparatus and an image processing method, according to the present invention, may sense an identifier positioned in a tip to identify unique information such as a serial number of the tip, and may update tip use information assigned to the identified unique information. In some cases, in connection with updating the tip use information, the use information may also be selectively updated based on the type of a scan target to be scanned. Alternatively, a scanning operation of the image processing apparatus may be restricted when a predetermined elapsed time from the removal to the mounting of the tip after scanning an oral cavity is not ensured. Due to the above-mentioned configuration, a user can conveniently recognize when to replace the tip.
