Stereoscopy (also called stereoscopics) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word stereoscopy derives from Greek ÏÏÎµÏÎµÏÏ (stereos) , meaning firm, solid, and ÏÎºÎ¿ÏÎ­Ï (skopeÅ) , meaning to look, to see. Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope.
The word stereo comes from the Greek word stereos which means firm or solid. With stereo vision you see an object as solid in three spatial dimensions--width, height and depth--or x, y and z. It is the added perception of the depth dimension that makes stereo vision so rich and special. Stereo vision--or stereoscopic vision --probably evolved as a means of survival.
