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.
In image processing, motion blur is one of 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. This is due to the switching times and the decay behaviour 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 the way people see. The representation converted on the retina is subject to a certain persistence.
