Abstract
The present invention provides a camera device which can be applied to communication devices such as a mobile phone. The camera device of the present invention has divided movement regions of a movable lens group. The movable lens group is actuated at a large width in any one movement regions to perform a zoom operation. The movable lens group is actuated at a small width in the other movement region to perform a focusing operation. Accordingly, the camera device of the present invention allows miniaturization, and can provide a zoom and a focusing function.
Claims57
A compact camera device for communication devices, comprises:
