Abstract

The invention relates to a liquid lens, and the liquid lens comprises a deformable cavity, wherein a convex cavity is provided with an inner cavity capable of being filled with liquid; and at least one flexible liquid guide pipe of which one end is connected with the cavity and is communicated with the inner cavity of the cavity, wherein the inner cavity and the liquid guide pipe are both filled with light-transmitting liquid, so that the light-transmitting liquid in the inner cavity forms a lens shape. According to the liquid lens, when the liquid guide pipe is compressed, liquid in the liquid guide pipe can flow into the inner cavity, so that the shape of the inner cavity is changed, the focal length of the liquid lens is changed, and the zoom requirement of a projector can be met. The invention further provides an imaging system with the liquid lens and an electronic device with the imaging system.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a liquid lens, an imaging system with the liquid lens, and an electronic device with the imaging system. Background technique [0002] A development trend of mobile electronic devices is to use multiple cameras, each of which has a specific function. Generally, the multiple cameras include a common RGB camera, an ultra-wide-angle RGB camera, an IR (infrared) camera, and the like. Among them, the IR camera is used for TOF (TIme Of Flight, time-of-flight ranging) 3D imaging, and the IR camera needs to be used with an infrared projector to obtain the depth information of the target. Image fitting can obtain a 3D image of the target. When the ordinary RGB camera and the ultra-wide-angle RGB camera take pictures, the shooting area (field of view) covered by the two is different in size, but the field of view (FOV) of the current infrared projector is fixed, so the infrared pr...
