       HCFR PATTERNS (1/6)

The #YHCFR Colormeter#Y software
allows for profiling and
calibration of displays using the
combination of a pattern
generator to create test patterns,
and a #Ctristimulous colorimeter#C to
read and measure the outputs.
Then you, as the user, will have
to change settings on your
display in order to refine the
results and attempt to match the
chosen standard of video color
reproduction.

The #YHCFR Colormeter#Y software is
at the heart of the system. It
interprets the results from the
colorimeter and provides #CCIE
color#C differences (Delta E
values), chromaticity diagrams,

To set up #YHCFR Colormeter#Y,
attach your colorimeter
to your computer, open the
program, click #CFile -> New#C, and
select DVD Manual as your
selected generator. Select your
colorimeter from the list, and
click OK.

Once in #YHCFR Colormeter#Y, click
#CAdvance -> Preferences#C.

       HCFR PATTERNS (3/6)

Under the #CGeneral#C tab, ensure
that the section #CColors to add
when measuring primaries and
secondaries#C is set to #YWhite#Y. 

Under the #CReferences#C tab, choose
your color space. #YPAL/SECAM#Y is
recommended for #CPAL CRT#C users.
#YSDTV - REC601 (NTSC)#Y is
recommended for #CNTSC CRT#C users.
#YHD TV REC 709#Y is recommended
for #CHD#C and #CUHD/4K#C in #CSDR
flat panel TV#C users. #YsRGB#Y is
recommended for #CPC VGA#C and up
#CCRT monitors#C. 

White point is normally #YD65#Y
(default) for western regions of
all color space types.


                       #C(cont...)#C
       HCFR PATTERNS (4/6)

#YJapanese SDTV#Y often used #YD93#Y as
a white point (which will appear
cooler, or bluer, than #YD65#Y).

Most gamma calculations normally
default to #CITU-R BT.1886#C, which
uses #CDisplay Gamma Power Law 2.4#C.
Your device may have a different
native gamma response, so choose
a different Power Law value if
required. #YsRGB#Y has a specific
non-linear gamma that cannot be
customized. 

Ensure your options chosen here
match the test pattern list you
choose in the #C240p Test Suite#C.

When you are ready to start
measuring, click the #CMeasure#C
menu, and select your measurement.
If any large scale changes are
made to your display, it is
recommended to re-run a
#CGray-scale sweep#C often, so that
baseline calculations can be
accurately made for #CDelta E#C
measurements.

A menu will pop up asking you to
select a given #CDVD chapter#C and
#Ccolor name#C. Use the #YL#Y and
#YR#Y buttons to scroll through
the color list and select the
color desired. Once ready to
measure, click #COK#C in #YHCFR
Colormeter#Y to measure the test
pattern.

Use the #CContinuous measure#C mode
to be able to adjust your
display's settings to match the
values required for your chosen

color space, white point, gamma,
etc.
