In the process of acquiring the image by the mobile terminal, the first display touch component is displayed in a preview interface corresponding to the image acquisition component positioned on the second surface. In addition to the first display touch device 11, various other icons or buttons are displayed on the preview interface.

For another example, the brightness of the flash of the image capturing assembly on the first surface is lower than that of the image capturing assembly on the second surface, so that the requirement of beautifying in self-photographing can be met.
Therefore, when the image acquisition assembly of the second surface is used for self-shooting, the acquisition parameters of the image acquisition assembly of the second surface can be adjusted based on the distance.
Illustratively, the capture parameters include capture focal length, sensitivity, flash brightness, or white balance, and the embodiments of the present disclosure are not limited herein.

In one embodiment, the mobile terminal adjusts the acquisition focal length of the image acquisition component based on the distance, including:
when the distance is within the preset range, the default acquisition focal length corresponding to the outside of the preset range is adjusted to the acquisition focal length corresponding to the inside of the preset range.
It should be noted that, the distance of the acquired object is different, and the acquisition focal distance corresponding to the image acquisition component is also different. Therefore, the acquisition focal length of the image acquisition assembly can be flexibly adjusted based on the distance.
Illustratively, the predetermined range in the embodiments of the present disclosure includes a range of 30 centimeters to 50 centimeters, and the embodiments of the present disclosure are not limited herein.
It can be understood that, mobile terminal is at the in-process of gathering the image, what the acquiescence of the image acquisition subassembly of second surface adopted is that the collection focus outside the scope of predetermineeing gathers the image, therefore, when using the image acquisition subassembly of second surface to autodyne, need will follow acquiescence and be corresponding to the collection focus outside the scope of predetermineeing, adjust to the collection focus that is corresponding to the scope of predetermineeing, so, can adjust the best focus that adapts to this distance with gathering the focus, and then obtain the better auto heterodyne image of effect.

In the embodiment of the disclosure, the display duration of the turning prompt can be set according to actual use requirements. For example, the display duration of the flipping hint may be 5 seconds or 3 seconds, and embodiments of the present disclosure are not limited herein.
It should be noted that the turning prompt may be directly displayed on the first display touch component to prompt the turning of the mobile terminal, or the turning prompt may be displayed by the first display touch component, and the turning of the mobile terminal is prompted by a combination manner of the first display touch component turning on the screen.
For example, as shown in fig. 5, when the first operation instruction is to acquire the object oriented to the first display touch component, the first display touch component displays a prompt box, and prompt information for turning over the mobile terminal is displayed in the prompt box.
It can be understood that the embodiment of the disclosure can flexibly adopt different modes to prompt the mobile terminal to turn over according to requirements, so that the prompting modes are richer.

After the second surface of the mobile terminal faces the object, a second operation acting on the second display touch component can be detected, image acquisition is carried out based on the second operation, and the acquired image is displayed.
It should be noted that the second operation acting on the second display touch component may include, but is not limited to, an operation of indicating to capture an object oriented by the second display touch component.
For example, the second operation may be generated by clicking, sliding, or voice acting on the second display touch component, and the embodiments of the present disclosure are not limited herein.
It can be understood that in the embodiment of the present disclosure, a self-timer can be performed by using the image capture component on the second surface of the mobile terminal, and a self-timer image can be displayed by using the second display touch component on the second surface of the mobile terminal, so that the mobile terminal can perform self-timer.
The following description of the image acquisition method in the embodiments of the present disclosure is made by taking a mobile terminal as a mobile phone and an image acquisition component as a camera as an example.
Fig. 6 is a third exemplary flowchart of an image capturing method shown in the embodiment of the present disclosure, and as shown in fig. 6, the method for implementing image capturing by a mobile phone includes the following steps:
s21, the mobile phone detects a first operation acting on the first display touch component.
S22, the mobile phone determines whether the first operation is an operation for indicating to acquire the object oriented by the first display touch control assembly.
And S23, when the first operation instruction is used for acquiring the object oriented by the first display touch control assembly, the first display touch control assembly turns off the screen, the second display touch control assembly positioned on the second surface is lightened, and the camera positioned on the second surface is oriented to the object.
And S24, detecting the distance between the camera and the object.
And S25, adjusting the acquisition parameters of the camera based on the distance.
And S26, acquiring the image of the object by using the camera with the adjusted acquisition parameters.
In the embodiment of the disclosure, the mobile phone enters the preview interface corresponding to the camera on the second surface during the process of image acquisition, and the preview interface is displayed on the first display touch component. At the moment, the mobile phone detects a first operation acting on a preview interface displayed by the first display touch component.
It should be noted that different buttons may be displayed on the preview interface, and each button corresponds to a different operation. For example, the button a correspondingly acquires the object oriented by the first display touch component, and when the mobile phone detects that the button a is touched, it can be determined that the first operation applied to the first display touch component is the operation indicating acquisition of the object oriented by the first display touch component.
For another example, the B button corresponds to capturing a panoramic image, and when the mobile phone detects that the B button is touched, it may be determined that the first operation applied to the first display touch component is an operation indicating entering a panoramic image capturing mode.
In the embodiment of the present disclosure, when the first operation instruction acquires the object to which the first display touch component faces, the first display touch component disappears from the screen, and the second display touch component located on the second surface is lighted. That is to say, when the first operation instruction is used for acquiring the object towards which the first display touch component faces, the overturning prompt of the mobile phone is output, and the overturning prompt is used for prompting that the camera on the second surface faces the object.
It should be noted that, the camera acquisition parameters required for acquiring a short-distance object by using the camera on the second surface are different from those required for acquiring a long-distance object by using the camera on the second surface. Therefore, when the camera on the second surface faces the object, the distance between the camera and the object needs to be detected, and then the acquisition parameters can be adjusted based on the distance to acquire the image.
It can be understood that, in the case that the camera is eliminated from the first surface of the mobile phone, that is, the camera on the first surface cannot be used for self-shooting, the embodiment of the present disclosure may perform self-shooting based on the camera on the second surface. And because the camera on the second surface can adjust the acquisition parameters according to the distance between the camera and the object, the camera on the second surface is utilized to acquire images, and images with better effect can be obtained.
