Ultra Quiet 28dBA Operation
Fan noise during projector operation can be distracting
during a presentation or videoconference. The 8000 series
projectors operate at a significantly low noise level of only
28dBA (i.e., using a single lamp in "low lamp" mode). As a
result, presentations and conferences can be held without the
annoyance of a projector fan.
Examples of Noise Levels
20dB : Rustling leaves, the ticking of
a wall clock (from 1m in front)
30dB : A whisper, a suburban
area very late at night
40dB : A quiet neighborhood,
Geometric Correction
Keystone Correction
n
Trapezoidal distortion caused when the projector is not
positioned directly in front of the screen is corrected in both
vertical and horizontal directions.
Cornerstone Correction
n
Pixel conversion is used to correct trapezoidal and diagonal
distortion that causes oblique images, ensuring the proper
aspect ratio.
Curved Surface Projection Correction
n
These projectors are equipped with a
function for correcting distortion that
occurs when projecting images onto
curved surfaces. This advanced feature
is practical for unique applications such
as projecting images onto pillars at
special event sites.

Edge Blending and Colour Matching
Edge Blending
n
Edge blending creates a seamless image by adjusting the
brightness at adjoining edges when using multiple projectors
side-by-side to reproduce single widescreen images. This
feature can also be utilised for top-bottom projection or a
combination of side-by-side and top-bottom images; for
example, when images are projected from four projectors
in a two-by-two arrangement.

Colour matching
The colour matching function corrects variations in the colour
reproduced by each projector when multiple projectors are
used simultaneously. This colour homogenization enables
the integrated display of images.
