| 三菱发布其最新家用投影机HC3100，该机型可以说是三菱HC3000的升级版本，采用美国德州仪器TI最新研发的"65 WXGA DarkChip3"核心，1,280×768分辨率，开口率达到90%以上，对比度5000:1，亮度1000流明，相对HC3000有了不少改进。 三菱HC3100使用1.2倍手动镜头，100寸（16:9）画面最少需要3.6米投影距离。其独特的可用遥控器控制开关的2段式光圈，在追求亮度时选择打开，而在观赏电影时可以关闭光圈提高画面黑色的下潜度；4倍-5倍速自由选择的色轮能够忠实表现色温度6500K的D65标准光，影像还原更加真实自然；12bit咖码辅正和"Brilliant Color"技术则可以让画面各阶层的过渡愈加平稳，提升整体影像的层次感；DDP3020数字电路通过将输入信号进行10bit I/P变换、12bit动态修正后高速LVDS(Low Voltage Differential Signal)驱动，最终实现4倍于8bit投影机的细微画面差别；3种咖码模式和2种用户模式满足了不同消费者的使用需求，并配备了开机既在最短时间内自动调整至最佳状态的台形辅正机能。 | | | | The HC3100'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. | | | | | 8-bit (256 steps) | | 10-bit (1024 steps): Approx. four times the number of gradations | | | | | The HC3100 is equipped with the latest DMD panel (D3) featuring an expanded mirror operation angle of 12 degrees. In addition to its exceptional light usage efficiency, this new panel's performance is further enhanced by the new motor-driven iris lens optical engine, achieving a high contrast ratio of 4500:1. The variable lens aperture optimally adjusts picture quality according to image content. Bright scenes are clear and vibrant, while dark scenes have subtle gradations and sharp black reproduction. This much sought-after wide range of expression is finally a reality. | | | | | | | 2000:1 contrast (Mitsubishi Electric's previous model) | 4500:1 contrast | All-glass lens | | | A full 10-bit I/P conversion circuit significantly reduces noise, for smooth, beautiful images with fewer ”jaggies” (stair-like lines). | | | | | Previous 8-bit | New 10-bit | | | 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. |
