Description

微云台防抖装置Micro-head anti-shake device 技术领域Technical field
本公开涉及通信领域,具体而言,涉及一种微云台防抖装置。The present disclosure relates to the field of communications, and in particular, to a micro-pan-tilt anti-shake device.
背景技术Background technique
带有摄像头的电子设备一直都被人们所推崇,特别是到了智能电子设备时代,摄像头更是成为了智能电子设备的标配。随着人们大众对拍照效果越来越苛求,很多在专业相机上的技术也运用到了电子设备的摄像头上,例如防抖技术。现在电子设备上的防抖大致分为采用电子防抖和OIS光学防抖。电子防抖主要通过程序对传感器上的图像进行分析和采集,当照片被拍糊时,利用边缘图像对模糊部分进行补偿,从而实现“防抖”,但其实现原理更像是对照片进行“后期处理”,治标不治本,并没有什么实际作用。光学防抖是通过在镜片组中增加一个使用磁力悬浮的镜片,配合陀螺仪工作,当机身发生震动时,能检测到轻微的抖动从而控制镜片浮动对抖动进行一定的位移补偿,从而避免了光路发生抖动,实现光学防抖。但由于摄像头模组结构原理等原因,OIS光学防抖大部分仅支持横向和纵向的平移抖动补偿(两轴防抖),因此防抖能力有一定的局限性。Electronic devices with cameras have always been admired by people, especially in the era of smart electronic devices, cameras have become the standard configuration of smart electronic devices. As people become more demanding for photo effects, many of the technologies used in professional cameras have also been applied to the cameras of electronic devices, such as anti-shake technology. The anti-shake on electronic equipment is roughly divided into the use of electronic anti-shake and OIS optical anti-shake. Electronic image stabilization mainly analyzes and collects the image on the sensor through a program. When the photo is blurred, the edge image is used to compensate for the blurred part to achieve "anti-shake", but its realization principle is more like a photo. "Post-treatment" means treating the symptoms but not the root cause, and has no practical effect. Optical image stabilization is achieved by adding a magnetically suspended lens to the lens group and working with a gyroscope. When the body shakes, it can detect slight jitter so as to control the floating of the lens to compensate for the jitter to a certain extent, thereby avoiding The optical path is jittered to achieve optical anti-shake. However, due to the structural principle of the camera module and other reasons, most of OIS optical image stabilization only supports horizontal and vertical translational shake compensation (two-axis image stabilization), so the anti-shake capability has certain limitations.
针对相关技术中,电子设备的摄像头的防抖能力不足的技术问题,尚未提出有效的技术方案。Aiming at the technical problem of insufficient anti-shake capability of the camera of an electronic device in the related art, no effective technical solution has been proposed yet.
