The above steps will be specifically described with reference to specific examples.

In step S310, a first image obtained by shooting a target area with the standard dual cameras and a second image obtained by shooting the target area with the wide-angle camera are obtained.

In this embodiment, the standard dual cameras include a first camera and a second camera. Taking the mobile terminal 100 as a mobile phone as an example, the first camera, the second camera and the wide-angle camera may be a front camera or a rear camera of the mobile terminal 100.

In this embodiment, the photographing method further includes:

step S3503, preview output is carried out on the target image;

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

The above-mentioned serial numbers of the embodiments of the present application are merely for description and do not represent the merits of the embodiments.

Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solutions of the present application may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal (such as a mobile phone, a computer, a server, an air conditioner, or a network device) to execute the method according to the embodiments of the present application.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.

Claims

1. A photographing method is applied to a mobile terminal and is characterized in that the mobile terminal comprises a standard double-camera and a wide-angle camera, and the photographing method comprises the following steps:

2. The photographing method of claim 1, wherein the standard dual cameras comprise a first camera and a second camera, and the step of acquiring the first image of the target area captured by the standard dual cameras comprises:

3. The photographing method according to claim 2, wherein the step of acquiring the first image of the target area captured by the standard dual cameras further comprises:

4. The photographing method according to claim 1, wherein the field of view of the standard dual cameras is located within the target area; the field of view region of wide angle camera is located in the target area and contains the field of view region of two cameras of standard.

5. The photographing method of claim 2, wherein the image data information of the first image further includes image data information of the subject.

6. The photographing method of claim 5, wherein the step of fusing the first image and the second image based on a preset fusion algorithm and image data information of the first image to generate a target image comprises:

7. The photographing method according to claim 6, wherein after the step of fusing the cropped subject to the second image according to the preset fusion algorithm to generate the target image, the photographing method further comprises:

8. The photographing method according to claim 6, wherein the photographing method further comprises:

previewing and outputting the target image; and

9. A mobile terminal, characterized in that the mobile terminal comprises:
