摘要:
An intra-oral camera (10) includes an imaging system (12), an imaging sensor (16) and an image stabilization apparatus (14) comprising a liquid lens (36), lens driver elements (38), a microprocessor (34) and a motion sensor (32). The motion sensor (32) provides a motion signal indicating camera movement. The adjustable liquid lens (36) has an interface between first and second immiscible liquids and is actuable to change refraction with respect to a first axis in response to a first adjustment signal at a first pair of electrodes and with respect to a second axis in response to a second adjustment signal at a second pair of electrodes. The microprocessor (34) is responsive to stored instructions for obtaining the motion signal from the motion sensor (32) and in communication with lens driver elements (38) for providing the first and second adjustment signals to the adjustable liquid lens (36).
