képstabilizáló

Képstabilizáló refers to image stabilization technology, a feature found in cameras and lenses designed to reduce blur caused by camera shake. This phenomenon is particularly noticeable during handheld photography, especially in low light conditions or when using long focal lengths, where even slight movements can lead to unsharp images.

There are two primary types of image stabilization: optical and digital. Optical image stabilization (OIS) physically counteracts camera movement. This is typically achieved by moving lens elements or a sensor within the camera body. Gyroscopic sensors detect the camera's motion, and the stabilization system adjusts accordingly to keep the image steady on the sensor.

Digital image stabilization (DIS) is a software-based solution. It works by analyzing the captured image and digitally shifting or cropping the frame to compensate for shake. While it can be effective, DIS can sometimes lead to a loss of image quality or a reduction in the field of view.

Many modern cameras and lenses incorporate képstabilizáló, significantly improving the chances of capturing sharp, clear photographs and smooth video footage, especially when a tripod is not available or practical. The effectiveness of image stabilization is often measured in "stops," indicating how much slower a shutter speed can be used while still achieving a blur-free image.
