运动相机 技术领域
本发明涉及一种相机，尤其涉及一种运动相机。
背景技术
传统的运动型相机由于本身不带有机械增稳功能，在剧烈运动的情况下所拍摄的图片或视频质量不高。为了对该运动型相机进行增稳，现有的解决方式是将相机外接于云台上，并使该云台装设于可移动装置（如无人机）上。然而，上述方式，将会导致可移动装置体积增大，且不便携带。
发明内容
鉴于上述状况，有必要提供一种小型化并能够实现增稳功能的运动相机。
一种运动相机，其包括外壳以及摄像头，所述运动相机还包括至少部分设于所述外壳内的云台机构，所述摄像头设于所述云台机构上并能够通过所述云台机构稳定拍摄及/或调整拍摄角度。
上述运动相机通过内置的方式将云台机构及摄像头分别设置于运动相机的外壳内，以防止云台机构及摄像头分别受到外界因素的干扰发生晃动的问题，进而实现对运动型运动相机的增稳效果。同时，将云台机构及摄像头分别设置于运动相机的外壳内还可进一步缩小运动相机的整体体积，提高了运动相机的便携性。
