Abstract

A dual camera module includes a circuit board, a mirror base, two image sensors, two lens modules, a liquid crystal lens and soldering pins, the two lens modules are installed on the same mirror base, the bottom surface of the mirror base and the The circuit board is connected, and a liquid crystal lens is set on the top surface of the mirror base to cover the two lens modules. The welding pins in the mirror base can electrically connect the liquid crystal lens to the circuit board. During the assembly process, the lens module has been Adjust the focus, and use the liquid crystal lens to focus when taking pictures, that is, the circuit board supplies power to the liquid crystal lens through the welding pins, and correspondingly changes the optical path of the light passing through the liquid crystal lens at different voltages, and realizes the focusing function without a voice coil motor. Therefore, the magnetic interference between the two voice coil motors can be effectively avoided, thereby improving the picture quality. Moreover, the focusing function of the two lens modules is realized through a liquid crystal lens, so the problem of inconsistency in motion of the two lens modules can be effectively solved, and the picture accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to a dual camera module. Background technique [0002] At present, electronic devices such as mobile phones, notebook computers, and tablet computers are emerging new technologies that use dual camera modules to shoot the same object at the same time. dimensional image. [0003] A traditional dual camera module consists of two independent camera modules mounted on the same circuit board. Each camera module includes a lens module, a voice coil motor as an actuator and carrying a corresponding lens module, an image sensor for collecting captured image information, a control circuit and an image back-end processor. The main components of the voice coil motor are the coil, the magnet and the shrapnel. When the current is energized, the coil generates a current, thereby inducing a magnetic field of a certain strength. Under the combined action of the magnetic field generated by ...
