Title:
LENS MODULE AND IMAGING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/245358
Kind Code:
A1
Abstract:
A lens module (1) and an imaging apparatus. The lens module (1) comprises a plurality of lenses, wherein at least one of the plurality of lenses is a liquid lens (13), and at least one is a movable lens (12); a light-transmitting film (131) of the liquid lens (13) can deform under the effect of an external force, and a fluid flows to make the curvature of the light-transmitting film (131) change, so that focusing or zooming is realized; and the movable lens (12) can move in the direction of an optical axis so as to realize focusing. The change in the curvature of the light-transmitting film (131) facilitates enlarging a zooming range of the lens module (1), improving the focusing efficiency and changing the phenomenon of lens distortion. A focusing effect obtained by the movable lens (12) cooperates with the change in the curvature of the light-transmitting film (131) of the liquid lens (13), thereby solving the problem of reduction in the zooming range due to dependence on the change in the curvature of the light-transmitting film (131) of the same liquid lens (13) to realize focusing and zooming, and also solving the problems of insufficiency of apparatus space and reduction of focusing efficiency due to dependence on the movable lens (12) to realize focusing and zooming. Therefore the focusing efficiency is further improved and the zooming range is further enlarged.
