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 value that represents the related color in
a light source in general. In this projector,
the color temperature is used to adjust the
RGB color balance for the projected
image to correct the related color influ-
ence by the ambient light. If you increase
and decrease the color temperature, white
changes to blue and red, respectively. You
can set the color temperature in the [Color
adjustment] menu if [Photo] has been
selected for [Image mode].
Lightning environment around the projec-
tor. You can correct and project an image
more appropriately according to the ambi-
ent light on the screen via the setting of
[Ambient light] if you have selected
[Photo] for [Image mode].
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.
