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.
* For an LCD projector producing 1,100 lumens or more, as of September 2005.
