Image capture method and electronic device

An electronic device, comprising:

• a display;
• a camera;
• one or more processors coupled to the camera and the display;
• and
• a memory coupled to the one or more processors and configured to store instructions that, when executed by the one or more processors, cause the electronic device to be configured to:
• capture a preview image via the camera;
• obtain a human face yaw angle of each frame of the preview image, wherein the human face yaw angle is a left/right rotation angle of an orientation of a face of a first user relative to a first connection line, wherein the first user is photographed by the camera, and wherein the first connection line is a line connecting the camera and a head of the first user;
• and
• store a jth frame of preview image if human face yaw angles from an ith frame of the preview image to a kth frame of the preview image meet a preset condition, wherein the kth frame of the preview image is a frame of the preview image currently captured by the camera, 1≤i≤j≤k, and i, j, and k are all integers,
• wherein the preset condition comprises the human face yaw angle of the ith frame of the preview image is greater than a first angle threshold, human face yaw angles from the ith frame of the preview image to the jth frame of the preview image show a decreasing change trend, and the human face yaw angle of the jth frame of the preview image is less than a second angle threshold.

A non-transitory computer-readable storage medium, comprising instructions that, when executed by one or more processors of an electronic device, cause the electronic device to be configured to:

• capture a preview image via a camera of an electronic device;
• obtain a human face yaw angle of each frame of the preview image, wherein the human face yaw angle is a left/right rotation angle of an orientation of a face of a first user relative to a first connection line, wherein the first user is photographed by the camera, and wherein the first connection line is a line connecting the camera and a head of the first user;
• and
• store a jth frame of preview image if human face yaw angles from an ith frame of the preview image to a kth frame of the preview image meet a preset condition, wherein the kth frame of the preview image is a frame of the preview image currently captured by the camera, 1≤i≤j≤k, and i, j, and k are all integers,
• wherein the preset condition comprises the human face yaw angle of the ith frame of the preview image is greater than a first angle threshold, human face yaw angles from the ith frame of the preview image to the jth frame of the preview image show a decreasing change trend, and the human face yaw angle of the jth frame of the preview image is less than a second angle threshold.
