Problems solved by technology

[0002] With the popularization of digital devices such as smart terminals and cameras, taking pictures at any time has become a part of people's life, and taking pictures with friends has become a joy of life, but when many people take pictures together, especially when taking selfies, camera shots The captured headshots are incomplete, especially at the edge of the lens. Because the focal length of the lens is too small, it is impossible to fully capture all the people participating in the photo, and it is impossible to make all the people participating in the photo be in the same frame.

Embodiment 1

[0033] refer to figure 1 , a method for automatically adjusting the focal length for taking pictures, comprising:

[0034] S101. Obtain the head portrait captured by the lens.

[0035] The headshots of the people participating in the photo are taken, and the headshots that can be captured by the lens are obtained, wherein the headshots include the face and head corresponding to the headshots in the lens.

[0036] S102. Analyze the avatar, and acquire avatar information corresponding to the avatar.

[0037] Among them, the avatar captured by the lens is analyzed through the avatar recognition function.

[0038] The analysis method adopted is not specifically limited in the present invention, and methods such as head portrait feature extraction or head portrait contour extraction can realize the function of analyzing the photographed head portraits.

[0039] In this embodiment, analyzing the avatar includes analyzing the face and head corresponding to the object, and obtainin...

Embodiment 2

[0045] refer to figure 2 , another method of automatically adjusting the focus for taking pictures, including:

[0046] S201. Obtain the head portrait captured by the lens.

[0047] The headshots of the people participating in the photo are taken, and the headshots that can be captured by the lens are obtained, wherein the headshots include the face and head corresponding to the headshots in the lens.

[0048] S202. Acquire the distance between the avatar and the lens.

[0049] After obtaining the head portrait of the person participating in the photo taking, the distance between the head portrait and the lens is obtained through the distance sensor.

[0050] S203. Analyzing the avatars whose distance to the lens is less than or equal to a preset distance threshold, and acquiring the avatar information corresponding to the avatars whose distance to the lens is less than or equal to the preset distance threshold.

[0051] The specific analysis method at this time is the sam...

Embodiment 3

[0060] refer to image 3 , a camera system for automatically adjusting the focal length, comprising an avatar acquisition module 101, a first analysis module 102 and a focal length adjustment module 103;

[0061] Avatar acquisition module 101: used to acquire the avatar captured by the lens.

[0062] The headshots of the people participating in the photo are taken, and the headshots that can be captured by the lens are obtained, wherein the headshots include the face and head corresponding to the headshots in the lens.

[0063] The first analyzing module 102: for analyzing the avatar, and acquiring the avatar information corresponding to the avatar.

[0064] Among them, the avatar captured by the lens is analyzed through the avatar recognition function.

[0065] The analysis method adopted is not specifically limited in the present invention, and methods such as head portrait feature extraction or head portrait contour extraction can realize the function of analyzing the pho...

Abstract

The invention discloses a photographing method and system capable of automatically adjusting a focal length. The method comprises the following steps: obtaining a head portrait photographed by a camera lens; analyzing the head portrait to obtain head portrait information corresponding to the head portrait; and when determining that the head portrait information is not complete, adjusting the focal length of the camera lens until the head portrait information is complete. According to the photographing method and system, when the head portrait information corresponding to the head portrait photographed by the camera lens is not complete, the focal length of the camera lens is automatically adjusted, so that the head portraits of persons participating the photographing can be completely photographed by the camera lens, and furthermore, the head portraits of the persons participating the photographing can be in the same picture; and a condition that face information and head information in the photographed picture are not complete is avoided, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of photographing, in particular to a photographing method and system for automatically adjusting the focal length. Background technique [0002] With the popularization of digital devices such as smart terminals and cameras, taking pictures at any time has become a part of people's life, and taking pictures with friends has become a joy of life, but when many people take pictures together, especially when taking selfies, camera shots In the case of incomplete portraits, especially at the edge of the lens, because the focal length of the lens is too small, it is impossible to fully capture all the people participating in the photo, and it is impossible to make all the people participating in the photo be in the same frame. The present invention automatically adjusts the focal length of the camera when the avatar information corresponding to the avatar captured by the lens is incomplete, so that the face and h...
