Method and device for rapidly opening mobile phone camera for performing video recording

Abstract

The invention discloses a method and a device for rapidly opening a mobile phone camera for performing video recording. The method comprises the following steps: detecting and judging whether the current placement mode of a mobile phone is a vertical-screen mode or a transverse-screen mode; monitoring the angular speed value and direction value of the mobile phone through a gyroscope sensor; judging whether the mobile phone is rotated forwardly once or not according to the current placement mode of the mobile phone and the angular speed value and direction value of the mobile phone; performing reverse rotation once within a preset time interval; and if the condition is satisfied, directly opening a camera application of the mobile phone and starting recording of a video. Therefore, video recording can be performed directly through simple gesture operation. Rapid opening of the mobile phone camera and video recording can be realized without any complex unloading step, any camera opening step, operation of a touch screen or physical buttons. The method and the device are particularly suitable for shooting under emergency situations or sudden situations.
