Double-camera module group

Abstract

The invention relates to a double-camera module group, and the module group comprises a circuit board, a lens seat, two image sensors, two lens module groups, a liquid crystal lens, and a welding pin. The two lens module groups are disposed on the same lens seat, and the bottom surface of the lens seat is connected with the circuit board. Moreover, the top surface of the lens seat is provided with the liquid crystal lens, thereby enabling the liquid crystal lens to cover the two lens module groups. The welding pin in the lens seat can enable the liquid crystal lens to be electrically connected with the circuit board. During assembly, the focuses of the lens module groups are adjusted, and the liquid crystal lens is used for focusing during photographing. In other words, the circuit board supplies power to the liquid crystal lens through the welding pin. The path of light passing through the liquid crystal lens is correspondingly changed during different voltages, and the focusing function is achieved under the condition of no voice coil motor. Therefore, the module group can effectively prevent the magnetic interference between two voice coil motors, and improves the image quality. Moreover, the two lens module groups achieve the focusing function through the liquid crystal lens, so the module group can effectively solve a problem that the movement of the two lens module groups is not consistent, and improves the image quality.

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 ...
