Digital Image Stabilization (DIS) is a technology used in cameras and smartphones to reduce blurriness caused by camera movement during photo or video capture. It works by analyzing the image data and adjusting the output to compensate for any shake or vibrations, resulting in clearer and more stable images. DIS can be particularly useful in situations where holding the camera steady is challenging, such as while walking or in low-light conditions. By smoothing out the motion, DIS enhances the overall quality of the visual content, making it more enjoyable to view and share.
