Abstract

The embodiment of the invention discloses a photographing method. The method comprises the following steps: acquiring a target image through a front camera, determining at least one human face region contained in the target image; computing an area value corresponding to each human face region; according to a preset offset computing formula, computing a definition offset reference value corresponding to each human face region with the area value as the independent variable and the definition offset reference value as the dependent variable; performing sharp processing of image on the human face region according to the definition offset reference value to obtain a photographed image to save. Furthermore, the embodiment of the invention discloses a photographer. Through the adoption of the method disclosed by the invention, the definition of the face region can be improved when the front camera is used for photographing multi-people.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for taking pictures. Background technique [0002] With the continuous development of terminal technology, the camera function has become an indispensable function in mobile terminals, and most mobile terminals have dual cameras, that is, a front camera and a rear camera. [0003] However, due to cost control or other constraints, the front cameras installed in mobile terminals such as smartphones are generally fixed-focus cameras, that is to say, the focus point of this camera is fixed within a fixed interval or range, such as 30cm or 50cm. Generally speaking, when the user is taking a selfie, the distance between the face area and the lens is about the same, so the above-mentioned fixed-focus camera will not cause the user's face area to be unclear. However, in the case of taking a group photo with multiple people, because the distance between ea...
