Hitachi HDPJ52 Leisure Home Theater LCD Projector

Hitachi Updated: 2007-09-24

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 more true, life-like image.

Hi-2 Dual Iris System:
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.

Super Focus Quattro ELD Lens System:
For optimal picture accuracy and detail, and correction of "keystone" effect.

High Definition Capability:
The HDPJ52 utilizes true 16:9 3-Panel 720P LCD light engine and an exclusive Super Focus Quattro ELD lens system to reproduce High Definition images with incredible clarity.

Installation Flexibility:
Optical lens shift, both vertical and horizontal, allows the HDPJ52 to be placed off axis from screen center, but uses lens shift to center the picture on the screen not digital correction which degrades picture quality. A 1.6x zoom lens also allows the unit to be positioned at various distances from the screen, as close as 9'2" or as far as 15' from a 100" screen.

Exclusive 8-step Gamma Curve Adjustment:
Black levels are critical to any television picture, but especially so for Front Projector displays. The 8-Step gamma adjustment allows for adjustment of specific grey scale values without effecting the overall contrast. A gamma fine tuning feature is needed to obtain the best image for any screen type and viewing environment.

5 Preset Picture Modes and 4 Memory Modes:
For ease of use in any environment 5 Preset Picture Modes create global changes to several key picture adjustments to suit varied environments and source material. If detailed calibration or adjustment is applied, 4 memory modes can be saved for specific viewing needs.

Backlit Remote Control and Easy Menu System:
An ergonomic backlit remote control allows for one button access to the most commonly used features. The motorized 10-step Iris control works directly from the remote. An Easy Menu is available for simplified operation after initial setup is completed.

RS-232C Interface:
Allows for the projector to be incorporated into system control for advanced designs. Incorporate the HDPJ52 into an operating system which can control all aspects of the home theater environment including room lighting, picture settings, as well as motorized screen and ceiling mount options.
