Tracking video method based on rotary camera and terminal

Abstract

The invention discloses a tracking video method based on a rotary camera. The method comprises steps: an external fitting of a terminal is opened according to a preset starting mode, and when the included angle formed by the external fitting and the display screen of the terminal is more than or equal to a preset angle, a rotation video mode of a camera arranged on the external fitting is started; a target recording object set by a user is obtained, and moving data of the target recording object is determined according to the moving state of the target recording object; the rotation direction of the camera is determined according to the moving direction of the target recording object, the rotating speed and the rotating acceleration of the camera are determined according to the moving speed and the acceleration of the target recording object; the camera is triggered to rotate and record according to the original state and the rotating speed of the camera, and the camera rotates in the rotation direction according to the rotating acceleration. The provided method is advantageous in that operation stability of figure tracking video can be raised, the video recording quality is raised, and the user experience of the terminal is enhanced.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method and terminal for tracking video recording based on a rotating camera. Background technique [0002] At present, with the increasing popularity of mobile phones and the increasingly powerful recording function of mobile phone cameras, more and more mobile phone users like to take pictures or record videos with their mobile phones. In the prior art, when a mobile phone user uses the video recording function of the mobile phone to track and record people in application scenarios such as outdoor activities or character performances, a handheld device is required for tracking and recording. If the video recording time is long, the user of the handheld device will experience arm shaking or unstable holding height due to overweight phenomena such as arm soreness; or during video recording, because the movement of the handheld device and the movement of the recording...
