Mitsubishi Electric HC7800D Overview page 4

Integrating Imaging Technologies Cultivated and Evolved Over the Years
Newly developed Variable Iris provides high 100,000:1 contrast
An optimal iris shape for the DLP TM element and a linear motor are incorporated,
achieving high-speed, highly precise automatic control. Even in continuously
changing bright and dim scenes, blacks are traced and adjusted instantaneously.
This ensures that high-definition images from sources such as high-definition
television broadcasting and Blu-ray players are reproduced with their original beauty.
New Variable Iris (HC7800D)
High 1,500lm luminance with clear, high-definition images
In addition to Variable Iris, a high-power lamp is adopted, providing both enhanced
image brightness and contrast. The high 1,500-lumen brightness ensures that, in both
2D and 3D, high-resolution images are clearer, sharper and more vivid than ever.

High-performance extra-low-dispersion lens for
full high-definition resolution (with V-lens shift)
Compared to commonly used glass lenses,
the projector is equipped with a
high-performance extra-low-dispersion (ED)
lens system comprised of a total of 13 lenses
in four groups. Chromatic aberration is
minimized to the fullest and image resolution
is improved throughout, including the
periphery.

Color management function for easy fine-tuning of colors
The projector is equipped with a new color management function for independent
color R (red), G (green), B (blue), C (cyan), M (magenta) and Y (yellow))
adjustment of "Hue," "Saturation" and "Brightness." It is also possible to adjust a
specific color; when a color is selected only the objects of that color are shown in
color (others are in monotone), making it possible to tune colors to preference
more easily.

FRC installed – Reproduce content supplemented with
optimal frame number
Applying motion-vector analysis technology, data from the previous and
HC7800D
succeeding images are used to produce highly accurate image frames.
HDTV
HC4000
The optimal number of frames is supplemented to match the contents and
the final image is reproduced. As a result, motion blur in the vertical, horizontal
and diagonal directions is suppressed.
True Video Mode
Blur is suppressed using video image motion interpolation.
New frames are created from previous and succeeding images.
