Abstract

The invention discloses a method and device for automatically setting a shooting mode and relates to the technical field of electronic products. The method and device for automatically setting the shooting mode solves the problem that in the prior art, most users are not familiar with shooting mode selection under different scenes when using a cellphone, so that the shot effect is not ideal, and inconvenience can be brought to users. The method includes: starting a human face detection function of a shooting device, obtaining image information for identifying each human face region in a preview interface of the shooting device, calculating a first scale value of a maximum human face region area in the preview interface to the preview interface area according to the image information and the physical dimension of the preview interface, setting the shooting mode of the shooting device as a character mode when the first specific value is larger than or equal to a first threshold value, and setting the shooting mode of the shooting device as a non-character mode when the first specific value is smaller than the first threshold value. An embodiment of the method and device for automatically setting the shooting mode is used in a process for setting the shooting mode.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a method and device for automatically setting a shooting mode. Background technique [0002] With the popularization of camera functions in smart phones, using a mobile phone to take pictures has become one of the commonly used functions of the mobile phone. [0003] Since most users are not familiar with which shooting mode of the mobile phone needs to be used in which scene, the effect of the photos taken is not ideal, which brings inconvenience to the user. Contents of the invention [0004] Embodiments of the present invention provide a method and device for automatically setting a shooting mode, which realizes the automatic setting of the shooting mode and improves the shooting effect. [0005] In order to achieve the above object, embodiments of the present invention adopt the following technical solutions: [0006] In one aspect, the present invention provi...
