Number of dots in each resolution
If you select SXGA+ (1400 dots x 1050
dots) as the display resolution for the con-
necting computer, this projector can
project high-resolution images. If your
computer does not have the SXGA+
option, select the maximum resolution
among the selectable options.
An image display system used to display
the entire screen per scan. For an inter-
lace signal (video signal) that displays one
screen by two scans (one for odd lines
and one for even lines) is input, progres-
sive processing is required. When the pro-
gressive function is turned off, one screen
is displayed using image signals per inter-
lace signal, deteriorating the vertical reso-
lution of the image. When the progressive
function is turned on, one screen is dis-
played using image signals per two inter-
lace signals, improving the vertical
resolution of the image. Turn off the pro-
gressive function when flickering and hori-
zontal lines are noticeable on a fast-
moving picture.
A parameter that shifts the reproduction
range of a brightness signal from black to
white within an image signal toward the
higher or lower level of brightness. The
reproducibility of the dark tone is mainly
changed. Since you can adjust the offset
for each RGB color in this projector, you
can also adjust colors.
The offset is normally adjusted with the gain.
A tone adjustment system used during
projection of image data. The gamma cor-
rection function works effectively when
portions of an image are obscure because
they are too light or dark.
This projector supports manual gamma
correction and dynamic gamma correction
which performs the gamma correction
automatically.
A parameter that adjusts the reproduction
range of a brightness signal from black to
white within the image signal to naturally
reproduce it on the screen. The reproduc-
ibility of the bright tone is mainly changed.
Since you can adjust the gain for each
RGB color in this projector, you can also
adjust colors. The gain is normally
adjusted with the offset.
A memorized color is a color in our mem-
ory. The memorized color such as blue for
the sky is more vivid than the real color, so
you may feel colors of a projected image
are dull. If such is the case, enable the
memorized color correction function to
make the colors close to the ones in our
memory. You can enable the memorized
color correction function in the image
adjustment menu.
