Face capturing method and related apparatus

A face capturing apparatus applied to an electronic apparatus comprising a plurality of buffers, each of the plurality of buffers corresponding to a first number, the face capturing apparatus comprising:

• an analyzing unit configured to analyze a captured first video stream to obtain a plurality of images, each image corresponding to a first frame number;
• a determining unit configured to determine a first pattern comprising a plurality of first codes, each of the plurality of first codes corresponding to a second number, each second number corresponding to at least one first frame number, and a value of each of the plurality of first codes used to indicate whether an image of the first frame number corresponding to the first code is buffered;
• a buffering unit configured to buffer images of first frame numbers, corresponding to the first codes, indicating images to be buffered, to buffers in sequence, each buffer configured to store one image;
• the determining unit further configured to, when buffering the images, determine a second pattern comprising a plurality of second codes, each of the plurality of second codes corresponding to a third number, each third number corresponding to at least one second frame number, wherein an image corresponding to the second frame number is an image of the plurality of images that is not currently buffered in the buffer, and a value of each of the plurality of second codes used to indicate whether an image of the second frame number corresponding to the second code is buffered;
• the buffering unit further configured to buffer images of second frame numbers, corresponding to the second codes, indicating images to be buffered, to the buffers in sequence;
• and
• a face recognition unit configured to, when buffering the images, circularly process the images in the buffers in sequence on the basis of a face capturing algorithm and according to an order of the first numbers of the buffers, to obtain face images, and outputting the face images.
