Embodiment 1

[0040] refer to figure 1 , which shows a flow chart of a shooting method in Embodiment 1 of the present invention, which is applied to a mobile terminal with a camera, and may specifically include the following steps:

[0041] Step 101: Obtain a frame of preview image captured by the camera of the mobile terminal.

[0042] In the embodiment of the present invention, the mobile terminal can shoot the target person through the camera, and collect a preview image of the target person. For example, the mobile terminal can use a camera to capture images of a group photo of multiple people and collect a preview image of a group photo of multiple people. In step 101, after entering the shooting preview mode, the camera starts to collect each frame of preview images, and obtains a frame of preview images collected by the camera of the mobile terminal.

[0043] Step 102: Obtain the shooting distance and face size value of each face in the preview image.

[0044] In the embodiment of...

Embodiment 2

[0054] refer to Figure 2a , which shows a flowchart of a shooting method in Embodiment 2 of the present invention, which is applied to a mobile terminal with a camera, and may specifically include the following steps:

[0055] Step 201: Obtain a frame of preview image captured by the camera of the mobile terminal.

[0056] In the embodiment of the present invention, the mobile terminal can shoot the target person through the camera, and collect a preview image of the target person. After the mobile terminal enters the shooting preview mode, the camera starts to collect each frame of preview image, and obtains a frame of preview image collected by the camera of the mobile terminal.

[0057] For example, a mobile terminal user shoots a group photo scene with 50 people in total. The shooting distances of these 50 people from the mobile terminal are inconsistent, some are far and some are close. After the mobile terminal enters the shooting preview mode, the camera starts to cap...

Embodiment 3

[0174] refer to Figure 6a , shows a structural block diagram of a mobile terminal embodiment in Embodiment 3 of the present invention.

[0175] Figure 6a The mobile terminal 600 shown can include: a preview image acquisition module 601, a face information acquisition module 602, a target face determination module 603, a target face enlargement module 604, an image storage module 605 and a camera 606.

[0176] The preview image acquisition module 601 is used to obtain a frame preview image collected by the camera of the mobile terminal;

[0177] Facial information acquisition module 602, used to obtain the shooting distance and the face size value of each face in the preview image;

[0178] A target face determination module 603, configured to determine at least one target face to be enlarged in the preview image based on the shooting distance and the face size value of each face;

[0179] A target face enlargement module 604, configured to perform enlargement processing o...

Abstract

The embodiment of the invention provides a shooting method which is applied to a mobile terminal with a camera. The shooting method particularly can comprise the steps of: acquiring one frame of preview image acquired by the camera of the mobile terminal; acquiring a shooting distance and a face size value of each face in the preview image; based on the shooting distance and the face size value of each face, determining at least one target face to be amplified in the preview image; carrying out amplification processing on the at least one target face to generate a first target image; and generating a second target image from the preview image, and carrying out association storage on the first target image and the second target image. According to the shooting method provided by the embodiment of the invention, amplification on a face at a long shooting distance can be implemented, so that features of five sense organs of a target figure are clearly displayed, and an imaging effect of the image is improved; and moreover, the second target image which is not processed at all and the first target image subjected to amplification processing can be provided for a user to select, so that selections of the user are enriched.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a photographing method and a mobile terminal. Background technique [0002] With the rapid development of electronic equipment technology, the popularity of mobile terminals such as smart phones and tablet computers is getting faster and faster, and the camera pixels of mobile terminals are also continuously improving. Using mobile terminals to take group photos of multiple people or self-portraits to record life, It has gradually become a daily living habit. [0003] When an existing mobile terminal takes a group photo of multiple people, if the person is far away from the camera, the head portrait of the person farther away from the camera in the captured image will be relatively small, and even the facial features cannot be seen clearly, resulting in The image is distorted. Moreover, since the camera lens of the mobile terminal is an optical camera lens, there is a ...
