Embodiment 1

[0025] This embodiment provides a photo processing method based on face recognition, which is applied to a mobile terminal with a zoom camera, such as figure 1 As shown, the method includes step 110 to step 130.

[0026] Step 110, detecting human faces in the preview image of the camera.

[0027] After the mobile terminal enters the camera mode, the camera will collect images to be captured and display them on the display screen for users to preview. After entering the camera mode and before pressing the shutter button to take a photo, the image collected by the camera is called a photo preview image. There may be multiple faces in the photo preview image, such as figure 2 shown. First, it is necessary to detect the faces in the photo preview image, and determine the number and position of the faces. In the prior art, there are many methods for detecting human faces in images. For example: using the pre-trained face template to perform a sliding window search on the phot...

Embodiment 2

[0065] Based on Embodiment 1, in another embodiment of the present invention, such as Figure 5 As shown, the photo acquisition method based on face recognition also includes:

[0066] Step 140, image processing is performed on the facial image of the successfully recognized target face. During specific implementation, the image processing includes: any one or both of beauty and makeup.

[0067] In the present invention, after controlling the camera to focus on the target face according to the face recognition result and taking a clear photo of the target face, further image processing can be performed on the facial image of the target face in the captured photo. During specific implementation, the position and contour information of the target face in the captured photo is acquired, and the part within the contour of the face is used as an editing area for image processing.

[0068] Take the image processing as beauty beautification as an example. After focusing on the targ...

Embodiment 3

[0071] Another embodiment of the present invention also discloses a mobile terminal, which is provided with a zoom camera (not shown in the figure), such as Figure 6 As shown, the mobile terminal also includes:

[0072] Face detection module 610, for detecting the face in the photo preview image;

[0073] The face recognition module 620 is used to identify the target face from the faces detected by the face detection module 610 according to the facial features in the preset target face image;

[0074] The focusing and photographing module 630 is configured to focus on the target face successfully recognized by the face recognition module 620 and take a photo.

[0075] In specific implementation, such as Figure 7 As shown, the face recognition module 620 further includes:

[0076] A selection unit 6201, configured to select the current face to be recognized;

[0077] The first human face image acquisition unit 6202 is configured to focus on the current face to be recogniz...

Abstract

The invention provides a picture obtaining method based on face identification, is applied to a mobile terminal provided with a zooming pick-up head, and belongs to the technical field of a computer, for solving the problem of low shooting operation efficiency caused by a manual mode of focusing a pick-up head to a certain face to be shot in the prior art. The method comprises the following steps: detecting a face in a shooting preview image; according to a face feature in a preset object face image, identifying an object face from the detected face; and focusing on the successfully identified object face and performing shooting. According to the invention, through identifying the object face and then controlling the pick-up head to be focused on the successfully identified object face for shooting, in the shooting process of the mobile terminal, focusing on the preset object face can be automatically realized, manual focusing is unnecessary, the shooting efficiency is improved, and at the same time, user experience of the mobile terminal during shooting is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a face recognition-based photo acquisition method and a mobile terminal. Background technique [0002] With the popularity of mobile terminals and the development of Internet applications, there are more and more applications using mobile terminals to take pictures, and mobile terminals with cameras have become the main tool for taking pictures. In the prior art, when using a mobile terminal to take pictures of people, by displaying a focus indicator frame in the center of the screen, the user manually adjusts the position of the mobile terminal to move the face to be photographed into the viewfinder range of the focus indicator frame, and then the camera automatically focuses to achieve Take a photo; or, when there are multiple faces in the photo preview image collected by the camera, the camera will select the face in the middle of the preview image or the face with the large...
