[0027] refer to figure 1 , showing a flowchart of a photographing method according to an embodiment of the present invention, which is applied to a mobile terminal with a rear camera, and the method may specifically include the following steps:

[0028] Step 101, controlling the rear camera to collect images in the shooting scene to obtain collected images;

[0029] Among them, when the user needs to use the rear camera of a mobile terminal (such as a mobile phone) to complete a high-definition selfie, the user can turn on the rear camera of the mobile phone to find a view, and then control the rear camera to collect images within the viewfinder range. The captured image is obtained and displayed on the preview interface of the main screen of the mobile phone.

[0030] Step 102, performing face recognition on the collected image, and determining the contour of the face in the collected image;

[0031] Before the user clicks the camera button, the embodiment of the present in...

[0038] refer to figure 2 , showing a flowchart of a photographing method according to another embodiment of the present invention, which is applied to a mobile terminal with a rear camera, and the method may specifically include the following steps:

[0039] Step 201, providing multiple positions of the face contour in the captured image for the user to choose;

[0040] Among them, in order to meet the user's need for a certain composition when using the rear camera to take a selfie, the face needs to be positioned at a certain position. Therefore, in this embodiment, when the user opens the back of the mobile terminal (such as a mobile phone) When setting the camera to enter the shooting mode, a position option can be provided on the main screen of the mobile phone, for example, according to the size of the photo to be taken, a blank photo containing a nine-square grid is provided, and the user can select from these nine positions (upper left, upper middle) , Upper Right, M...

[0068] refer to image 3 , shows a block diagram of a mobile terminal according to an embodiment of the present invention. The mobile terminal has a rear camera, image 3 The illustrated mobile terminal 300 includes:

[0069] The collection module 301 is used to control the rear camera to collect the images in the shooting scene to obtain the collected images;

[0070] The recognition module 302 is configured to perform face recognition on the collected image, and determine the contour of the face in the collected image;

[0071] Remind the photographing module 303, for if the profile of the human face is a complete profile of the human face, then control the light emitting device arranged on the mobile terminal to emit light to remind the user to take pictures;

[0072] The photographing module 304 is configured to photograph the collected image to obtain a photographed image according to the photographing instruction for the collected image.

Abstract

The embodiment of the invention provides a photographing method and mobile terminal.The method comprises the following steps: controlling the rear camera to acquire the image in the shooting scene to obtain the acquired image;the face recognition of the acquired image is performed to determine the face contour in the acquired image.If the face contour is complete, a light emitting device arranged on the mobile terminal is illuminated to alert the user to take a photograph;the acquired image is photographed based on a photographing instruction for acquiring image.In the embodiment of the present invention, when the user uses the rear camera to perform the self-timer, the user's face can be completely put into the lens without causing the human face part into or completely not into the mirror;Moreover, without re-shoot the photographs after found the failure of the taken photographs by users, the success rate of the photograph shooting is improved , and the shooting steps are simplified, and the user experience is improved.

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] When people use a mobile terminal to take pictures, they can use the front camera to take a selfie, but the pixels of the front camera are generally much lower than the pixels of the rear camera, which causes the problem of poor selfie imaging. [0003] And because the rear camera has the advantages of wider shooting angle and clearer images, people tend to use the selfie camera to take selfies, so as to obtain high-definition and wide-angle photos. [0004] However, since there is no main screen of the mobile terminal on the side of the rear camera, the current shooting picture captured by the lens cannot be seen when using the rear camera to take a selfie. Therefore, there may be a shooting scene where the human face is completely or partially out of the camera lens, that is, the user's human ...
