In the embodiment, a user operates the terminal according to the actual shooting requirement of the user, after the terminal receives the operation of the user on the double cameras, the terminal corresponds to the operation instruction of the user on the double cameras and generates a control signal for controlling the movement of the double cameras.
It should be understood that, both steps 101 and 102 are performed by a processor of the terminal, that is, when a user performs corresponding operations on the two cameras of the terminal, the processor of the terminal receives an operation instruction of the user, and after the operation instruction corresponds to the operation instruction, the processor generates a control signal for controlling the movement of the two cameras; the generated control signal is transmitted to the double-camera module of the terminal.
And 103, controlling the double cameras to generate relative linear displacement based on the control signal.

In a typical application scenario of the embodiment, when a user opens a camera of a terminal and performs shooting by using the camera of the terminal, the terminal may include, but is not limited to, a mobile phone, a PAD, a notebook computer, or the like, a display interface of the terminal may display an operation instruction for a user to operate, and the user performs an operation for two cameras on the terminal according to a shooting requirement of the user; the terminal determines the shooting requirements of the user according to the operation instructions of the user for the two cameras, namely, determines which mode of work the two cameras need to carry out.
Here, after the user opens the camera of the terminal, as shown in fig. 10, the display interface of the terminal displays a plurality of operation instructions, where the operation instructions include operation instructions that can be selected by the user, such as background blurring, image quality fusion, Three-Dimensional (3D) shooting, face beautification, panorama mode, background special effect, and normal mode, the user can select one of the shooting modes to operate according to the shooting requirements of the user, and the terminal determines which shooting mode the shooting requirements of the user belong to according to the operation instructions of the user, and determines the working modes of the two cameras.
And step 203, the terminal generates an electric pulse signal for controlling the movement of the two cameras based on the working mode of the two cameras.
Wherein the control signal comprises an electrical pulse signal.
In the embodiment, after determining which shooting mode the user needs to use the dual cameras to carry out, the terminal generates an electric pulse signal for controlling the dual cameras to move according to the determined shooting mode; here, different shooting modes correspond to different hardware current outputs, for example, background blurring corresponds to a first current output, image quality fusion corresponds to a second current output, and the like; for example, the first current output corresponding to the background blurring may be preset to have a fixed current value of 10mA, and the second current output corresponding to the image quality fusion may be preset to have a fixed current value of 2 mA.
The current values of the first current output and the second current output herein may be adjusted according to actual needs, and the above values are merely for illustration and are not used to limit the current values of the first current output and the second current output in this embodiment.
Of course, in the present embodiment, different shooting modes may correspond to different hardware voltage outputs, for example, background blurring corresponds to a first voltage output, image quality fusion corresponds to a second voltage output, and the like; the different current outputs corresponding to the different shooting modes may be different preset fixed voltage values.
And step 204, the terminal controls the double cameras to generate relative linear displacement based on the control signal.
The electric pulse signal generated by the terminal and used for controlling the movement of the two cameras is an instantaneous current value or an instantaneous voltage value output by the processor according to the determined shooting mode after the terminal determines which shooting mode is needed by a user, the instantaneous current value or the instantaneous voltage value is used for being output to the two camera modules, and the two camera modules receive the input of the instantaneous current or the instantaneous voltage and drive the two cameras to generate relative displacement.
In this way, in the present embodiment, the operating mode of the two cameras is determined by the user according to the operating instruction of the two cameras, the electric pulse signal for controlling the two-camera motion is generated based on the operating mode of the two cameras, and the distance between the two cameras is adjusted, so that different shooting requirements of the user, such as background blurring, image quality fusion, 3D shooting, face beautification, panorama mode, background special effect, and normal mode, are met.
