光学防抖(英语:Optical image stabilization),是指在照相机或者其他类似成像仪器中,通过光学元器件的设置,例如镜头设置,来避免或者减少扑捉光学信号过程中出现的仪器抖动现象,从而提高成像质量。

不过这款口袋摄像机不具备光学变焦功能,只支持4倍数码变焦。另外产品还内置了电子防抖功能。
While there is no optical zoom, a 4x digital zoom is standard. Electronic image stabilization also helps correct the traditionally shaky video common to pocket cameras.
他们是有一个小型的感应器,但闪光功能过于孱弱(也可以说根本没有)。长此以往,你便渐渐忘了真正照相机是拥有强大光学变焦或防抖技术的。
They have tiny image sensors but feeble (or nonexistent) flashes, and you can forget about "real" camera features like powerful optical zoom lenses or image-stabilization systems.
本文针对小型光学望远镜,设计一种体积小巧,耗电低,具有良好防抖效果的影像稳定系统。
In this paper, an anti-shake system is designed for small optical telescope, which has a compact size, low power consumption and good anti-shake effect.
