Beschreibung
Zusammenfassung:	An auto focus intraoral camera with liquid lens includes: a digital imaging sensor (304) for capturing a digital image of an object; a light source for illuminating the object; an imaging lens assembly (302) for directing the light from the object along an optical path toward the digital imaging sensor; a liquid lens (100) disposed in the optical path between the imaging lens assembly and the digital imaging sensor, where the liquid lens has an adjustable focal length; a driver (306) for applying a variable voltage to the liquid lens to control the focal length of the liquid lens; and a processor (308) for processing the digital image captured by the digital imaging sensor. Meanwhile, a continuously auto focusing method for an intraoral camera is disclosed.
