-Vision can be considered as the process of converting sensory information into knowledge of the objects in the environment and involves a very complex problem to be solved:

From a set of distorted two dimension images projected on the retina "a world must be created"

The eye is just a sensor and extracts only a part of the total information available and the brain is the primary organ of vision

To simplify we can define:

Seeing is the physical recording of the pattern of light energy received from the world that consists of:

  1. Selective gathering of the light
  2. Projection or focusing of the light on a photosensitive surface
  3. Conversion of the light into a pattern of chemical or electrical activity

Perceiving is the interpretation of what is seen

We will consider vision from the following points of view:
