Stereoscopy (also called stereoscopic or 3-D imaging) refers to a technique for creating or
enhancing the illusion of depth in an image by presenting two offset images separately to the left
and right eye of the viewer. These two-dimensional images are then combined in the brain to give
the perception of 3-D depth. Besides the technique of free viewing, which must be learned by the
viewer, three strategies have been used to mechanically present different images to each eye: have
the viewer wear eyeglasses to combine separate images from two offset sources, have the viewer
wear eyeglasses to filter offset images from a single source separated to each eye, or have the light
source split the images directionally into the viewer’s eyes .
Stereoscopy creates the illusion of three-dimensional depth from images on a two-dimensional
plane. Human vision uses several cues to determine relative depths in a perceived scene. Some of
these cues are:
Accommodation of the eyeball (eyeball focus)
Occlusion of one object by another
Subtended visual angle of an object of known size
Linear perspective (convergence of parallel edges)
Vertical position (objects higher in the scene generally tend to be perceived as further
Haze, desaturation, and a shift to bluishness
Change in size of textured pattern detail
