DEFAULT (default) –
This setting provides good black levels and high contrast
under optimum viewing conditions for virtually all types of images, including
video, HDTV and computer graphics.
ENHANCED –
This setting elevates middle gray levels compared to Default, and
provides a more gradual rolled-off transition to maximum white. Together, these
differences can improve the appearance of many kinds of images.
HIGH AMBIENT –
This setting elevates low gray levels compared to the Default
and Enhanced settings. In high ambient light conditions, details can be seen in
the dark parts of an image that would otherwise be difficult to perceive.
PAL/SECAM –
This setting results in a darker image with higher contrast. The
gamma curve more closely matches the official standard for PAL and SECAM
video signals.
NTSC ENHANCED –
This setting is similar to Enhanced, but results in a darker
image with higher apparent contrast.
LINEAR –
This setting is a straight, linear transition from black to white. For
normal source signals, it results in a picture of low contrast with highly elevated
low- and mid- level grays. It should be used only with sources that have their
own pre-applied gamma control.
Color Temperature Setup
– The Color Temperature Setup submenu allows you
to apply, alter, add, or copy a color temperature, or if you want to use an unaltered
factory default color temperature.
By default, the projector can utilize any of four calibrated factory-set color
temperatures: 3200, 5400, 6500 or 9300 (expressed in degrees Kelvin). For most
applications, these temperatures will display accurate and realistic colors from a
variety of sources. They can be selected at any time in either the Image Settings
menu (4. Color Setup) or in the Color Temperature Setup menu.
Figure 3.13. Color Temperature Setup Menu
However, if you require extra color temperatures, you can also add up to five custom
color temperatures–four User and one Interpolated–by defining them within the
Color Temperature Setup menu (each defaults to 6500K until then). Any User or
Interpolated temperature created here is immediately applied, or it can be selected at
any time from the Image Settings menu (4. Color Setup) as usual, regardless of your
source or channel. The Color Temperature Setup menu options are described below.
NOTE: For best results, use an internal grayscale test pattern when working with
color temperature.
