Denotation
Persistence of vision is the optical phenomenon where the illusion of motion is created because the brain interprets multiple still images as one. When multiple images appear in fast enough succession, the brain blends them into a single, persistent, moving image. The human eye and brain can only process about 12 separate images per second, retaining an image for 1/16 of a second. If a subsequent image is replaced during this time frame, an illusion of continuity is created.
Description
Persistence of vision refers to a phenomenon in the human visual system that creates the illusion of continuous motion when a series of still Images is presented in rapid succession. In the context of the film industry this phenomenon is crucial to the creation of motion pictures.
The human eye retains an image for a fraction of a second after it disappears from view. When a film sequence of still Images is projected at a high speed, typically 24 frames per second in traditional filmmaking the persistence of vision causes the brain to perceive the sequence as smooth, continuous motion. This fundamental principle forms the basis of film animation and cinematography.
Filmmakers utilize the persistence of vision to create the illusion of movement and tell stories through moving Images. Each frame of a film is a snapshot of a moment in time and when these frames are played in rapid succession, the viewer sees a fluid and dynamic sequence. Special effects, animation and other visual storytelling techniques rely on this phenomenon to bring fictional worlds and characters to life on the screen.
The concept of persistence of vision has been instrumental in the development of film technology and the evolution of cinematic storytelling. Over time, filmmakers have experimented with frame rates, movie editing techniques and visual effects to enhance the impact of motion pictures. Understanding and harnessing the persistence of vision is essential for filmmakers to create compelling and immersive visual experiences for their audiences.
