Packed with imaging technologies acclaimed by professionals
Dynamic Iris and Dynamic Gamma
The Dynamic Iris helps provide the deeper, richer blacks needed
for true image reproduction. This technology adjusts the lamp
power, iris and gamma curve according to data obtained from
frame-by-frame histogram analysis of the image brightness
level. The adjustments are made 60 times per second.
The wide iris range, combined with histogram analysis that
detects as many as 3,000,000,000 brightness and darkness lev-
els, provides brighter bright scenes and deeper, richer blacks.
The Dynamic Gamma boosts the brightness level of image
details that would otherwise be lost in dark areas. You see the
kind of true, deep blacks you’ve seen before only at the cinema.
