It should be noted that, recognizing the facial expression presented by the acquired facial image of the photographed user may be implemented by an alternative manner, which specifically includes: and according to the acquired face image of the photographed user, recognizing the facial expression presented by the acquired face image of the photographed user according to a preset facial expression recognition algorithm.
For example, after the photographing application software acquires the face image, the facial expression presented by the acquired face image of the photographed user is recognized through a facial expression recognition algorithm preset by the photographing application software, through a facial expression recognition algorithm preset by the photographing application software built-in the intelligent terminal device.
It should be further noted that the facial expressions may include laughing, crying, surprise, frowning, fear, and the like, and it is to be supplemented that the preset facial expression recognition algorithm program may be an existing facial expression recognition algorithm program on the market, and by introducing the existing facial expression recognition algorithm program on the market into the photographing application software, when the photographing application software needs to recognize the facial expression presented by the acquired facial image of the photographed user, the facial expression recognition algorithm introduced into the photographing application software is called to recognize the facial image, so as to recognize the facial expression presented by the facial image.
Step 104: and if the photographed user is not the preset user, outputting the acquired face image of the photographed user.
According to the method, when a user takes a picture by using the picture taking function in the terminal equipment, firstly, a camera in the terminal equipment acquires a face image of the user to be taken, and whether the user to be taken is a preset user is judged; and then, if the photographed user is the preset user, recognizing the facial expression presented by the acquired facial image of the photographed user through a facial expression recognition algorithm built in the photographing program, and performing targeted adjustment on at least one part related to the facial expression, so that the output facial image can amplify the expression effect presented by the acquired facial image of the photographed user. And if the photographed user is not the preset user, outputting the acquired face image of the photographed user, thereby realizing the photographing of the personalized photo.
Specifically, step 103: and determining at least one part corresponding to the facial expression from the face in the acquired face image of the photographed user according to the facial expression presented by the acquired face image of the photographed user, and adjusting. Wherein the parts of the face include eyebrows, eyes, nose, and mouth. Of course, the parts of the face also include the cheeks and the chin.
The shape of the mouth, the shape of the chin, and the position of the cheek in the acquired face image of the photographed user may be adjusted, for example, when the facial expression presented by the acquired face image of the photographed user is recognized as smiling. For example, the rising radian of the two ends of the mouth corner, the width of the chin and the positions of the cheeks are adjusted, so that the output face image can enlarge the smiling expression effect presented by the acquired face image of the photographed user, and only one part, such as the mouth, can be adjusted.
In an alternative implementation, step 102: judging whether the photographed user is a preset user, as shown in fig. 2, includes:
step 201: acquiring corresponding identity information from preset identity information bound with the face image according to the acquired face image of the photographed user and a face information matching algorithm;
