The term motion blur is used for both motion blur and edge blur.
- Motion blur is a photographic effect in which parts of the photo appear blurred, creating the illusion of dynamism. Partial object, but it can also be the blurring of the background when the camera follows the moving object. Motion blur is always partial and does not apply to the entire photo, as it does when a photo is blurred. The effect of motion blur can be more or less pronounced with faster or faster shutter speeds. It depends on the relative motion between the camera and the object.Inimage processing, motion blur belongs to the special effects and can be set in the direction of motion.
- Edge blur is concerned with the representation of moving scenes on displays. Edge blur can occur on LCD displays at hard brightness and color transitions. These are due to the switching times and decay behavior of the individual liquid crystals, but also to the state of preservation of the display, which only changes when a new image is loaded. The effect of edge blur is also due to people's viewing behavior. The representation converted on the retina is subject to a certain persistence.
