Problems solved by technology

[0003] However, during the user's use, there will still be situations where the faces of the photos taken are too dark or too bright
For example, for a particularly dark person, the existing faceAE’s exposure intensity is not enough, and the face exposure is still very dark, or for a particularly white person, the existing faceAE’s exposure intensity is excessive, which will make the face special. Bright, hard to achieve perfect exposure

Abstract

The embodiment of the invention discloses a picture taking method and device. The method includes the steps of receiving a picture taking request triggered by a user, obtaining a human face luminance value, a background luminance value and color information corresponding to a human face skin color under a picture taking interface, determining a first face automatic exposure face AE weight according to the human face luminance value, the background luminance value and the color information corresponding to the human face skin color, taking a picture by using the first face AE weight to make the human face color in the picture be normal. The picture taking method and device can achieve a good exposure effect in taking the human face picture, so the human face skin color in the taken picture can be normal.

Description

technical field [0001] Embodiments of the present invention relate to information processing technologies, and in particular, to a photographing method and device. Background technique [0002] With the continuous development of science and technology, the existing mobile terminals (such as smart phones, Ipads, etc.) are also changing with each passing day in the technology of taking pictures, not only the automatic exposure of graphics processing software (Adobe After Effects, AE), but also the automatic exposure of human faces. Exposure (faceAE). [0003] However, during the user's use, there will still be situations where the faces in the photos are too dark or too bright. For example, for a very dark person, the exposure intensity of the existing faceAE is still insufficient, and the exposure of the face is still very dark, or for a very white person, the exposure intensity of the existing faceAE is excessive, which will make the face special. Bright, it is difficult t...
