Visual processing
Visual Processing
Visual processing (/ˈvɪʒʊəl ˈprəʊsɛsɪŋ/) is the sequence of steps that information taken in via the eyes goes through to enable the brain to understand its environment. The process involves several stages, from the detection of light by the retina to the interpretation of the information in the visual cortex.
Etymology
The term "visual processing" is derived from the Latin "visus" meaning "sight" and the Latin "processus" meaning "a going forward, advance, progress".
