三菱hc1100已经是目前性价比最高的720P家庭影院投影机
在投影机领域，日本三菱绝对算得上是一个实力派角色，旗下的DLP投影机HC系列更是深得业内发烧友的喜爱。10月下旬开始，三菱的最新两款720P投影机就要在国内上市发售了。
The HC1100's formatter board is equipped with a combined full 10-bit processing I/P converter and scaler, and a 12-bit floating point digital gamma controller. The result is approximately four times the number of gradations of a conventional 8-bit model, so even skin tones are faithfully reproduced.
A high-speed memory (RLDRAM) with improved data transmission efficiency, and a high-speed LVDS drive provide subtle gradations of expression rivaling high-end models.

The HC1100 is equipped with the latest 720p DMD panel (DC2) featuring an expanded mirror operation angle of 12 degrees. This advanced panel's exceptional light usage efficiency provides a contrast of 3000:1.

For more realistic color reproduction of the visual source, the HC1100 is equipped with a color wheel capable of reproducing the D65 light standard (6500 K).
A new color processing algorithm and system-level color signal image enhancement processing provide bright, vibrant reproduction of the neutral colors commonly found in videos and natural scenery. The three-stage adjustment function further enhances this breakthrough.
A full 10-bit I/P conversion circuit markedly reduces noise, for smooth, beautiful images with fewer ”jaggies” (stair-like lines).

The HC1100 features 2-3 pull-down to significantly reduce ”jaggies” in interlace (480i or 576i) movie sources. In addition, the combination of several functions also enables each mode -- either high brightness or high picture quality -- to be easily selected according to the image.
In addition to the 3 modes of sports, video, and cinema, for times when the normal brightness function cannot address user preferences such as a desire to increase black level reproduction, brighten neutral colors, or suppress highlights when watching a movie, the gamma correction function makes it possible to independently fine-adjust only the black level, neutral color, or white and gradations.
  
Operating noise has been reduced to just 26 dB by employing a low-noise fan and redesigning the shape of the color wheel holder and lamp fins. Moreover, the optimal temperature control design used for the 200W light source lamp extends the lamp's useful life to a maximum of 3000 hours.
*Maximum of 3000 hours at low mode and 2000 hours at standard mode.
*Lamp life is defined as the average time until brightness is reduced by half; it is not a guaranteed life for all lamps.
*Lamp life will vary considerably depending on the usage environment and conditions, and whether regular maintenance such as cleaning is performed.

In order to make it easier to align the projection angle with the center of the screen, the lens is positioned in the center of the unit. Hot air is expelled through a front exhaust for further installation flexibility
The HC1100 is equipped with HDMI input terminals, the next-generation interface standard. Connecting the projector to a DVD player or other device with HDMI output makes it possible to take advantage of the characteristics of DLP full digital processing. Digital processing of all signals with no analog conversion ensures that the image is projected with no deterioration. Color gain control at the time of input is also possible. (when there is a color difference)
*1 HDCP (High-bandwidth Digital Content Protection) is a copyright protection function for digital interfaces.
*2 HDMI (High-Definition Multimedia Interface) is a next-generation digital interface standard that features additional functions for home electronics, such as the copyright protection function HDCP (High-bandwidth Digital Content Protection), while maintaining compatibility with DVI (Digital Visual Interface) display interface technology.
HDMI, the HDMI logo, and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI Licensing LLC.
The overscan rate for images on DVDs and other media can be adjusted between 90% and 100% in one-percent increments (when an HDMI component is connected).
The HC1100 is equipped with a screen trigger that synchronizes raising and lowering of an electrically-operated screen with the projector power switch, so projection can begin at the touch of a button.
Digital trapezoidal distortion correction corrects screen distortion within ±40 steps vertically and ±25 steps horizontally (one step is equivalent to approximately one degree).

The image quality can be directly adjusted via the remote control. The remote control is lighted for easy operation even in a dark room.
