Although the earliest presentations of stereoscopic presentation can be traced as far
back as the 1890’s, the earliest confirmed viewing of a 3D motion picture by a paid
audience dates back to 1922.
A resurgence of 3D films in movie theaters occurred in the early 1950’s and introduced
the first color films to use this technology. The anaglyph method was used whereby 2
images were superimposed, in an additive light method, using color filters. The red and
cyan filters used required the viewer to wear special glasses with red and cyan lenses to
view the presentation. The glasses allowed the viewer’s eyes to filter out the added
colors and the result was a separate image for the left and right eye. Other than a slight
degradation in color rendering, this method worked satisfactorily.
Another resurgence of 3D movies occurred in the late 80’s and early 90’s. Some of the
film content still relied on the anaglyph method but a newer version utilizing polarized
lenses made its debut. Once again, the fad came and went.
Once again, 3D picture viewing is in the spotlight and, for the first time, it involves
television and home entertainment systems. The digital era and high definition TV, along
with the ability to store and move digital information at higher speeds than ever presents
a promising re-emergence of 3D.
Computer generated graphics used in movie production has greatly enhanced the
effects of video content, adding to the surreal sensation of 3D presentations. Add the
video gaming industry and some exciting possibilities lie ahead.
Sony has fully embraced the current 3D technology. By having access to source material
and developing leading edge technology to display it, Sony is poised to become the
leader in this new and exciting method of watching television.
