Introduction
Note
The Vidikron Vision Model 15 Series DLP Projectors combines a highly efficient optical light
engine with broad installation and integration options.
Vidikron has implemented a host of advancements into the projector’s light engine to take
full advantage of its widescreen, high-definition Digital Micromirror Device (DMD™) chip. The
Vision 15 features Enhanced GEN 3™ technology to produce deeper blacks, greater contrast
ratio and brightness, and richly saturated colors.
Among the Vision 15’s features are a sophisticated color-balancing system that results in the
industry’s best gray scale tracking, and far surpasses the capabilities of CRT projectors.
Accurate gray scale reproduction is vital to vibrant, true-to-life color reproduction, as well as
superior black level and white level performance. Vidikron’s acclaimed Imagix™ video
processing and scaling assure pristine video imagery, while the Vision 15’s generous light
output capability is powerful enough to handle screens as large as 96 inches wide with ease.
The Vision 15 features a 16:9 aspect ratio resolution of 1280 x 720. It provides an HDMI input
for pure digital video signal transmission. In addition, the projector’s broad lens shift
capability, variable throw distance, and electronic horizontal and vertical keystone correction
allow for flexible placement within virtually any theater environment. Discrete IR and/or
serial control makes it simple to partner the Vision 15 with other audio/video components
and automated control systems for a truly high-end, home cinema system.
For uncompromising widescreen reproduction of movies originally filmed in the “scope”
(2.35:1) format, the Vision 15 can be equipped with Vidikron’s patent-pending CineWide™
technology, a combination of software, electronics and high-quality anamorphic optics.
CineWide maintains constant vertical height on the screen just as in a movie theater. When a
viewer transitions from 1.78:1 (16:9) program material to 2.35:1, the image simply gets wider
while full height is maintained.
1.3
Description, Features and
Benefits
CineWide requires the use of a 2.35:1 or similar aspect ratio superwide format
screen.
