General Information

Precursors

Stereoscope

Error creating thumbnail: Unable to save thumbnail to destination
Stereograph of US Patent Building c. 1890.

Invented in 1838 by Charles Wheatstone, the stereoscope provides viewers with a still 3-D image. Two images are designed side-by-side separated by the same distance as the eyes to form a stereograph. This stereograph is then placed inside a stereoscope with magnifying lenses about two and a half inches apart. An article from 1859, describes “a stereoscope is an instrument which makes surfaces look solid” (Stereoscope). The stereoscope marks the beginning of 3-D imaging. 3-D television follows long after.

Types

Anaglyph

Anaglyph 3-D Glasses.

Anaglyph images are made up of two color coded images. Each image is designated for either the right eye which is usually green/blue or the left eye which is red. The two images form one 3-D image when viewed through special anaglyph glasses. The Dimension 3 Company employs cyan/red as they believe that this combination produces the least amount of blur or ghost images (Dimension 3). These blurred images are a constant problem with 3-D imaging. The proper colors must be identified in order to make the images clear.

Spatial Vision

Spatial Vision was developed by experiments by German astronomer Carl Pulfrich in 1922. Pulfrich discovered that “the rods of the eye – the receptors that work in dim light- take longer to perceive light than do the eye’s cones, which work in brighter light. Using special glasses that have one clear lens and one lens dark enough that only rod-sensitive light will pass through, the two eyes will see the same object a split-second apart. The brain will perceive that object to be closer than stationary one” (Taub). Spatial Vision requires the movement of an image back and forth in order to produce a 3-D image. Either the camera or the viewer has to be constantly moving. The viewer must wear glasses with one clear lens and one dark lens. However, unlike anaglyph, the image remains clear 2-D without the glasses. Anaglyph images when viewed without glasses appear blurry with colored outlines surrounding each image.

VISIDEP

In the early 1980s, Dr. Edwin Jones, specialist in optics, Dr. LeConte Cathey, specialist in electronics, and Dr. Porter McLaurin, specialist in media production created a 3-D process that does not involved special glasses or viewing equipment. Visual Image Depth Enhancement Process (VISIDEP) “produces images which have realistic depth and fullness, rather than exaggerated images which seem to leap outward” (Dead). The creators came up with this process after studying how visually impaired people perceive depth. VISIDEP basically follows the process of a one-eyed person by processing images presented at different angles at a rapid speed in order to produce a 3-D image. It was believed that VISIDEP would most immediately be used to televise sporting events and commercials. VISIDEP did not take off as a result of lack of interest and investors. The process did not impress enough people to be used as a marketing tool.

Future of 3-D TV

A new technology is expected to hit the market in as little as three years. This 3-D television will not require special glasses. Rather, the television itself will produce the 3-D image. A recent article in the Guardian describes “the technology works by throwing a different image to each eye and angling them so that one eye picks up one and the other picks up the other (Clapperton). Eight different images are used in an effort to reduce nausea and dizziness which were reported during the early stages of the technology. These complaints have followed 3-D television from the beginning as the eye is too strained in previous uses. Two 3-D films are supposed to be released in 2009, one by Steven Spielberg and one by James Cameron. However, a lot more content will be necessary in order to spur the purchase of these seemingly expensive devices. Orange, the early leader of this market, claims that 3-D television will become the primary television within ten years replacing conventional television. The television is predicted to cost about 20% more than a High Definition TV today.
