One key to enhancing picture quality is black reproduction. Panasonic
developed the new Dynamic Iris, with an expanded iris range, and a
new optical block to give the PT-AE900 deeper, richer blacks than
earlier home cinema projectors provided. By substantially expanding
the dynamic range available for expressing images, we achieved a
contrast ratio of 5500:1 along with the brightness of 1,100 lumen.
What's more, new Smooth Screen technology combined with a new
LCD panel allows the projector to reproduce smoother, more natural
looking images.
All this hard work paid off. Today the PT-AE900 is recognized as a
cinema projector suitable for professional video reproduction. It is even
used as a reference monitor on some movie sets.

New Dynamic Iris realizes world's first* 5500:1 contrast ratio with a brightness of 1,100 lumens
for deeper, richer blacks
New Smooth Screen technology
Other LCD home cinema projectors can suffer from the “screen door
effect”—black lines between pixels that mar the smoothness of the
images. New Smooth Screen technology, developed exclusively by
Panasonic, virtually eliminates this problem by providing the high
contrast ratio and other improvements that complement the new LCD
panel of the PT-AE900. Also, blurriness and flickering have been removed
during vertical panning, giving the PT-AE900 a sharp and detailed high-
definition picture that is remarkably smooth and realistic.

Cinema Color Management technology
The color correction system, Cinema Color Management (CCM),
was developed to enable free control of colors and has a proven
track record. Previously, it had been difficult to reflect the colorist’s
intentions, because correcting one color affected certain others.
With CCM technology, individual correction of approximately
1,070,000,000 colors without affecting other colors became possible.
Color control usually includes control of contrast, but CCM
technology goes even further and controls brightness too.
Incorporating CCM moves color correction closer to the process
used for motion pictures.
Rendering deep, rich blacks is essential to faithful video
reproduction. With this in mind, Panasonic added further refinements
to the highly regarded Dynamic Iris with scene-tracking capability.
Using data obtained from frame-by-frame histogram analysis of
brightness, digital image processing technology controls the lamp
power, iris, and gamma curve every 1/60 second, the industry’s
fastest. Now the iris range of the new Dynamic Iris has been extended
by about 60% compared to conventional models. This, combined with
histogram analysis employing algorithms for both brightness and
darkness, enables the PT-AE900 to render bright scenes more
brightly and dark scenes with deeper, richer blacks. Histogram
analysis can detect as many as 3,000,000,000 scene types. At the
same time, Dynamic Gamma boosts the brightness of picture details
that would otherwise be swallowed up in the dark portions. The
contrast ratio has been further increased by an optical system
upgrade that includes a new coating for the prism. The result of all
these improvements is the high contrast ratio of 5500:1 along with the
high brightness of 1,100 lumens. Enjoy the deep, crisp blacks you've
previously only experienced at the cinema.
