Easy Light Digital

Hitachi has been recognized as a world leader in the business front projector market, and now brings years of optical engineering and refinement to home theater. The advanced HDPJ52 is a perfect example of the total integration of Hitachi original technologies. The Hi-2 Dual Iris System is the combination of two independently controlled Iris components that adjust image brightness to show full shadow and highlight detail and enhance contrast for varied ambient light environments and source material. By optimizing the brightness of the projector to the ambient light conditions in the room, the viewer enjoys a more life-like picture with significantly improved shadow and highlight detail. Combined with the Super Focus Quattro ELD Lens System, the HDPJ52 brings out every detail and vivid color for a truer, life-like image.The Lamp Iris is automatically controlled by proprietary Hitachi processing circuitry. Independent of any motorized Lens Iris settings, the Lamp Iris is a "butterfly" valve, which opens and closes by degrees, directly in front of the lamp. This automatic feature dynamically controls the amount of light sent through the light engine to the LCD panels. Digitally mapping incoming frames to determine the correct position of the Lamp Iris allows for an impressive 7000:1 contrast ratio.
