Note that the two menus differ only in their user interface, so use whichever menu
best suits your needs and application.
•
Color Adjustments by X,Y — Enter known x/y coordinates from the
chromaticity graph.
•
Color Saturation — Adjust color slidebars and judge image color by eye or
meter.
A user-defined color “adjustment” can be applied for a source by selecting the
desired “User” option in the “Select Color Adjustment” list accessed in the Advanced
Image Settings menu.
COLOR ADJUSTMENT BY X,Y:
Use
this submenu if you want to alter,
add or copy a color gamut (i.e.,
“color adjustment”). Controls in
this menu define the precise hue of
each primary color component
(red, green, blue, and white) used
to generate the millions of colors
produced in displays. The x/y
coordinates for each color define
its location on the standard CIE
chromaticity graph (see Figure
3.23)—changing either or both of
these numbers will change the hue
of the color, and relocate the
“triangle” for possible colors. For
example, changing the x/y
coordinates for red will either
move the color closer to
orange or closer to violet,
which will in turn affect all
displayed colors having a red
component. Adjust the
slidebars or enter new
specific coordinates as
desired to define or change
up to four “User” color
gamuts needed for your
environment and
applications. Apply at any
time in the Advanced Image
Settings menu.
NOTE: Keep new x,y
coordinates within the
original color gamut triangle
shown here.
PROCEDURE FOR X,Y ADJUSTMENTS:
