Method for pre-starting multiple cameras of mobile terminal

Abstract

The invention discloses a method for pre-starting multiple cameras of a mobile terminal. According to the method, different operation gestures are set for a volume key on a mobile terminal, each operation gesture is correspondingly used for starting one camera, and the corresponding camera is started according to the operation gesture to the volume key by a user; the operation gesture comprises long pressing or continuous pressing for multiple times; each operation gesture can also be used for correspondingly selecting a photographing or video-recording mode while being used for starting the camera; and for example, the modes of front-facing camera photographing, front-facing camera video-recording, rear-camera photographing, rear-facing camera video-recording respectively correspond to one of volume key '+' long pressing, volume key '+' continuous pressing, volume key '-' long pressing and volume key '-' continuous pressing. According to the method for pre-starting mobile terminal multiple cameras, which is disclosed by the invention, the exposed volume key on the mobile terminal is set, so that the user can select by pressing one key to enter an appointed camera photographing or camera video-recording mode under the terminal screen locking condition, and quick switching among the multiple cameras can be realized.

Description

technical field [0001] The invention relates to the research field of mobile terminal equipment, in particular to a method for pre-starting multiple cameras of a mobile terminal. Background technique [0002] At present, in order to meet the needs of users, most mobile terminals are equipped with multiple cameras, which are divided into front cameras and rear cameras according to their installation positions. For video calls, the pixels are generally lower. The rear camera is used for daily shooting and has higher pixels than the front camera. When the user needs to take a picture, he needs to enter the shooting function first, and then the user determines which camera is currently on and whether it is what he needs. If he does not switch manually, he cannot pre-select which camera to open before starting the shooting function , which affects the user's operating experience. [0003] The Chinese invention patent with publication number CN102722321A discloses a method and ...
