Problems solved by technology

However, there may be many factors that cause the optical axes of the two lenses of the dual camera to be non-parallel, such as the original difference between the modules, the impact or drop of the subsequent mobile terminal, the gap between the lens motor and the bracket, and the differences between the two modules. Group installation errors, etc.
The various uncertain factors that cause the optical axes of the two lenses to be non-parallel will further complicate the composite correction of the two captured pictures by the software in the later stage, and the amount of correction that needs to be considered will be more, so it will increase the cost of software correction and composite The amount of calculation reduces the correction speed, and various uncertain factors will also make the correction not accurate enough, and the corrected image effect is poor

Embodiment 1

[0026] In the embodiment of the present invention, the lens motor includes a motor body and a driving device.

[0027] Wherein, the motor body is provided with a plurality of lens mounting positions, for example, two or three lens mounting positions, the number of lens mounting positions matches the number of lenses, and the specific number can be set as required.

[0028] There is a fixed angle between the central axes of the lens installation positions, for example, the included angle ranges from 0° to 180°. Specifically, the central axes of the lens installation positions can be parallel to each other. After each lens is installed in the corresponding lens mounting position, the optical axes of each lens will also form the same included angle. Each lens can be mounted on the corresponding lens mounting position through screw rotation.

[0029] The driving device is used for driving the lens mounted on the lens mounting position. The driving device is similar to that of th...

Embodiment 2

[0032] In this example, if figure 1 As shown, the lens motor includes a motor body 10 and a driving device (not shown in the figure). The motor body 10 is provided with two lens mounting positions 11, 12, the angle between the central axes of the two lens mounting positions is 0°, that is, the two central axes are parallel to each other, when the lenses 13, 14 are mounted on the corresponding lens mounting positions After position, the optical axis of lens 13,14 also can be parallel to each other. Wherein, the lenses 13, 14 can be mounted on the lens mounting positions 11, 12 through screw rotation. The apertures of the lens mounting positions 11 and 12 are the same.

[0033] The driving device in this embodiment may be a common driving unit that can drive the lenses 13 and 14 synchronously. Concretely, if the lens motor is a voice coil motor, then one way of realization may be that the lens mounting positions 11 and 12 use a common coil, and when the energized coil pushes ...

Embodiment 3

[0036] In this embodiment, the structure of the motor body in the lens motor is similar to the structure of the motor body in the second embodiment, and also has two lens mounting positions, and the central axes of the two lens mounting positions are parallel. However, in this embodiment, if figure 2 As shown, the apertures of the two lens installation positions 21 and 22 are different, so as to install lenses with different diameters. In other embodiments, when there are more than two lens mounting positions on the motor body, the apertures of some of the lens mounting positions may be the same, and the apertures of the remaining lens mounting positions may be different, so that lenses with different diameters may be set according to needs to achieve different shooting Function.

[0037] The driving device of the lens motor may be the same as that in the second embodiment.

Abstract

The embodiments of the invention provide a lens motor, a shooting device and a mobile terminal. The lens motor comprises a motor body and a driving apparatus. The motor body is provided with at least two lens installation positions, center axes of the at least two lens installation positions form a fixed included angle, and the driving apparatus is used for driving lenses installed on the lens installation positions. The lens motor simplifies the synthetic rectification process of software on pictures shot by each lens, improves the rectification speed, also improves the rectification precision at the same time, and improves the image effect after rectification.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a lens motor, an imaging device and a mobile terminal. Background technique [0002] With the widespread popularization of mobile terminals such as various mobile phones and PADs, people have higher and higher performance requirements for mobile terminals. Currently, many mobile terminals use dual rear cameras to improve the shooting performance of the mobile terminal. [0003] In the focusing mechanism of the existing dual rear cameras, the two groups of lenses and lens motors (such as voice coil motors) are independent of each other, that is, each lens uses its own lens motor to focus, and the two modules can move independently without affecting each other. However, there may be many factors that cause the optical axes of the two lenses of the dual camera to be non-parallel, such as the original difference between the modules, the impact or drop of the subsequent mo...
