Motor-driven variable lens aperture equipped, for optical

contrast adjustments that ensure optimal incident light

supply to the DMD chip. Two-level remote control switching

further streamlines use of selected brightness levels.

■ Further evolving the motor-driven iris lens with
2-level switching

■ New color wheel with true color reproduction
and handsome brightness

This projector features a DMD chip (wide panel) with

stellar 1024×576 dot resolution. Mirror inclination angle
of ±12 degrees effectively cuts black diffused light.
Besides this, the rear structure of the mirror uses dark

metal to block diffused reflection and stray light, setting

the scene for fine and rich gradation.

■ Dark chip 2-DMD, for high resolution of 1024×576

Movie film and other media recorded at 24 frames per

second are converted to 30-frame/sec. images, the same as

TV broadcasts. The bottom line is projection of high-detail

images closing in on the fine texture portrayed with film.

■ Mounted with 2-3 pull-down,
for classy reproduction of movie software

The digital trapezoidal distortion correction function

enables correction of picture distortion at ±20 steps.

■ Trapezoidal distortion correction

Image color and brightness signals are separated with

superb accuracy, using 3D processing. Cross color

(rainbow pattern noise) and dot interference (dotted

noise) are effectively curbed, while further use of the 10-

bit processing color decoder reproduces images with

even greater clarity.

■ Equipped with high picture quality reproduction circuit 3D Y/C separation, 10-bit color decoder

This projector produces outstanding brightness of 1000lm.

Even in living rooms or other brightly lit spaces,

comparatively flat video software or sporting events can

also be savored through top-quality images.

■ Top picture quality even in brightly light living
rooms, producing high luminance of 1000lm

■ Superb contrast to 4000:1

Equipped with an optical engine mounted with high-detail

all-glass lens, forging dramatic

improvements in contrast.

Motor-driven iris function lens

aperture further enhances the

package, elevating contrast to

the stellar level of 4000:1.

■ 25dBA low noise performance

Hushed low noise level of 25dBA realized with use of a low-noise fan,

color wheel holder configuration and lamp fin dimensions.

■ Center lens and front exhaust, for trouble-free installation and viewing

Adopted for redoubled ease in focusing the projected image at the center of the

screen is a center design that positions the lens at the center of the unit. And

with hot air released from the front-mounted exhaust port, there is no difficulty

in viewing from the side or behind the projector.

White has been added to the conventional color wheel
(made up of six color parts), boosting brightness to an

outstanding 1000lm. A special

coating is also used to raise

the reproduction of reds - a

vital color group for the sake

of image reproduction.

■ Illuminated remote control, easy to use
in darker rooms too

The system includes an illuminated remote control

panel, with the buttons lighting up for easy use

even in darkened rooms. Picture quality is also

corrected also by remote, enabling direct operation.
