Visual memory can be defined as the maintenance and processing of visual information after the source of that information is no longer available to the visual system. More than a store, visual memory can be considered as an encoding system for storing and retrieving information in a format that is inherently visual (i.e., retaining some of the original properties generated at the moment of sensory or perceptual processing), and therefore different from other formats, such as the verbal one.
