1.2 Major Features
●
New power-driven Turbo Bright System. Highest brightness of 3700 ANSI lumen in the
class
The projector achieves the highest brightness in its class with the Canon's original
Turbo Bright System and new optical design.
A remote control can be used to switch between Bright ON and OFF.
●
XGA LCD panel with contrast ratio of 800:1
A high contrast of 800:1 is achieved by improving transmittance of the 1.3" LCD panel
with 1024
×
768 pixels and using a contrast improvement filter.
High-quality SXGA projection is provided by XGA real projection and digital
compression.
●
Power-driven lens shift mechanism. Three types of optional replacement lenses
The power-driven lens shift mechanism can shift the projection screen position
vertically.
In addition to the standard lens, three types of optional replacement lenses (ultra wide
angle lens, wide angle zoom lens and long focus zoom lens) are available.
These functions can cope with various installation conditions, such as height and
distance, flexibly to provide high-quality projection all the time.
●
Video mode selection function suitable for projection data
The optimum gradation can be reproduced according to projection data for PC input
and video input by switching between video modes: standard/high contrast for PC
input and standard/cinema.
●
Clear PC image by DVI. High-quality video image by the progressive scan function
Supports digital interface (DVI) to reproduce clear PC images.
Uses progress scan to project higher-quality video and HDTV images.
●
37dB silent design
The fan speed is optimized by detecting the inside temperature.
The noise is suppressed by reducing the unnecessary increase in fan speed.
●
Extended Digital Keystone function, up to ±40 degrees
Smoothly corrects for "keystone" effect, giving a square image with up to 40 degrees
tilt.
