背景技术Background technique
随着移动终端的广泛使用以及终端拍摄技术的提升，人们越来越频繁地使用终端作为拍摄装置来拍摄图像或视频。传统摄像头的镜头通常被固定在终端上，拍摄人员只能通过移动终端的位置来对拍摄对象进行捕获，拍摄效率不高，难以适应不同的拍摄环境要求，且通常需要在终端中安装前置和后置摄像头才能实现普通拍摄和自拍的功能，因此，旋转摄像头因其可在终端中进行灵活地旋转而越来越流行。目前，利用旋转摄像头进行拍摄控制的方案主要为：根据不同的拍摄环境需要，用户通过手动旋转摄像头镜头的外壳来控制摄像头进行拍摄，这种手动控制方式的拍摄效率较低，摄像头旋转过程中的速度难以实现较为精准的调节，影响拍摄效果。With the widespread use of mobile terminals and the improvement of terminal shooting technology, people more and more frequently use the terminal as a shooting device to shoot images or videos. The lens of a traditional camera is usually fixed on the terminal, and the photographer can only capture the subject by moving the position of the terminal. The shooting efficiency is not high, and it is difficult to adapt to different shooting environments. Only the rear camera can realize the functions of ordinary shooting and Selfie, so the rotating camera is becoming more and more popular because it can be rotated flexibly in the terminal. At present, the shooting control scheme of using the rotating camera is mainly as follows: according to the needs of different shooting environments, the user controls the camera to shoot by manually rotating the shell of the camera lens. The shooting efficiency of this manual control method is low. It is difficult to adjust the speed more accurately, which affects the shooting effect.
