Optical stabilization is a technology used in cameras and smartphones to reduce blurriness caused by small movements during photography or videography. It works by adjusting the position of the camera's lens or sensor to counteract any shaking or vibrations, allowing for clearer images and smoother videos. This system is particularly beneficial in low-light conditions or when using zoom, where even slight movements can lead to noticeable blur. Many modern devices, including DSLR cameras, smartphones, and action cameras, incorporate optical stabilization to enhance image quality and improve the overall user experience.
