The obtaining module 301 is configured to obtain autofocus control data. The autofocus control data is preset and stored in a predetermined storage space. When the mobile terminal needs to scan a two-dimensional code image, the obtaining module 301 obtains the autofocus control data from the predetermined storage space.

Wherein, the camera lens includes motor, lens and chip. The adjusting module 302 is configured to implement adjustment of the auto-focus parameters of the lens by inputting the auto-focus control data into the chip of the lens before the lens scans the two-dimensional code image.

Wherein, the camera lens includes motor, lens and chip. The adjusting module 302 is configured to adjust the auto-focus parameters of the lens by inputting the auto-focus control data into the chip of the lens before the lens scans the two-dimensional code image.
And S403, the control module 303 controls the lens to scan the two-dimensional code image.
In the two-dimensional code image scanning method of the present embodiment, the auto-focus parameter includes an auto-focus speed.
The step S402 includes:
s502, the adjusting module 302 adjusts an auto-focusing speed of the lens according to the focusing control data, so that the lens automatically focuses the two-dimensional code image according to a predetermined focusing speed (adjusted auto-focusing speed).
Specifically, the adjusting module 302 increases the auto-focusing speed of the lens to a predetermined focusing speed (adjusted auto-focusing speed) according to the focusing control data, so that the lens automatically focuses the two-dimensional code image according to the predetermined focusing speed.
In the two-dimensional code image scanning method of this embodiment, the step S502 is:
the adjusting module 302 controls a motor of the lens to move a lens of the lens at a predetermined moving speed according to the focusing control data, so that the lens automatically focuses the two-dimensional code image at the predetermined focusing speed.

Since a user generally approaches the lens of the mobile terminal to the two-dimensional code image when the user scans the two-dimensional code image by using the mobile terminal, in this case, focusing the two-dimensional code image from a far-end focus may cause the efficiency of the automatic focusing operation of the lens to be very low.
Therefore, in this embodiment, the auto-focusing start position may be, for example, a near-end focus, that is, the adjusting module 302 adjusts the auto-focusing start position of the lens to be the near-end focus according to the focusing control data, so that the lens automatically focuses the two-dimensional code image from the near-end focus. This may allow the lens to complete auto-focus more quickly.

Wherein the auto-focus starting position corresponds to the predetermined position.
Specifically, before the lens automatically focuses on the two-dimensional code image, the adjusting module 302 controls a motor of the lens according to the focusing control data, so that the lens moves to a position corresponding to the near-end focus along a main optical axis of the lens under the driving of the motor, so that the lens starts to focus on the two-dimensional code image from the position corresponding to the near-end focus.
That is to say, in this embodiment, the adjusting module 302 controls the motor according to the focusing control data, so as to move the lens to the predetermined position along the main optical axis of the lens under the driving of the motor, and move the lens from the predetermined position along the main optical axis of the lens at the predetermined moving speed (predetermined step) under the driving of the motor, so that the lens automatically focuses on the two-dimensional code image from the predetermined position at the preset focusing speed.
