What does image stabilization do in a camera?

Image stabilization in a camera is designed to compensate for small movements and shakes that can occur while capturing photos or videos, resulting in clearer, more stable images. This technology helps to prevent motion blur and maintains image sharpness, especially in situations where the camera might be hand-held or when shooting in low-light conditions where longer exposure times are used.

The other choices focus on different aspects of image quality and camera functionality. Enhancing the color of images relates more to post-production editing or specific camera settings, rather than stabilization. Increasing zoom capability involves optical or digital zoom mechanisms, which do not impact the stability of a shot. Reducing the depth of field is a function controlled by the aperture setting and affects the focus range in the image, but it does not address image stability. Therefore, the correct answer highlights the primary function of image stabilization effectively.
