|
|
<h3>Summary</h3>
|
|
For Colorimeters that rely on a calibration matrix, <span
|
|
style="font-weight: bold;">ccxxmake</span> allows creation of a
|
|
correction matrix file (<a href="File_Formats.html#.ccmx">ccmx</a>)
|
|
for a particular <span style="font-weight: bold;">Colorimeter &
|
|
Display</span> combination, by making use a reference <span
|
|
style="font-weight: bold;">Spectrometer</span> or Colorimeter
|
|
instrument. This can then be used to improve the accuracy of
|
|
subsequent measurements with that Colorimeter on that Display by
|
|
using it with the <a href="dispcal.html#X">dispcal</a>, <a
|
|
href="dispread.html#X">dispread</a> and <a href="spotread.html#X">spotread</a>
|
|
-X option. A ccmx file can also be <a href="oeminst.html">installed</a>,
|
|
and will then appear in the available display type selection (<b>-y</b>
|
|
option). See <a href="WideGamutColmters.html">Wide Gamut Displays
|
|
and Colorimeters</a> for more information on why this may be
|
|
useful. [ <span style="font-weight: bold;">Note</span> that to make
|
|
use of a <u>colorimeter</u> as a CCMX reference, you will have to
|
|
provide two .ti3 files rather than using interactive measurement-
|
|
see <a href="#f"><span style="font-weight: bold;">-f</span></a>. ]<br>
|
|
<br>
|
|
For Colorimeters that have sensor spectral sensitivity calibration
|
|
information built into them (ie. the X-Rite <span
|
|
style="font-weight: bold;">i1d3</span>, and<span
|
|
style="font-weight: bold;"><span style="font-weight: bold;"></span></span>
|
|
DataColor <span style="font-weight: bold;">Spyder4 & Spyder5</span>),
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<span style="font-weight: bold;">ccxxmake</span> allows a creation
|
|
of a calibration spectral sample (<a href="File_Formats.html#.ccss">ccss</a>)
|
|
for a particular <span style="font-weight: bold;">Display</span>,
|
|
by making use a reference <span style="font-weight: bold;">Spectrometer</span>
|
|
instrument. This can then be used to improve the accuracy of
|
|
subsequent measurements on that Display using such Colorimeters, by
|
|
using it with the <a href="dispcal.html#X">dispcal</a>, <a
|
|
href="dispread.html#X">dispread</a> and <a href="spotread.html#X">spotread</a>
|
|
-X option, or it can be <a href="oeminst.html">installed</a>, and
|
|
will then appear in the available display type selection (<b>-y</b>
|
|
option).<br>
|
|
<br>
|
|
<u><b>NOTE</b></u> that there is no point in attempting to use both
|
|
a CCSS <u>and</u> a CCMX together, since they are just different
|
|
ways of arriving at the same 3x3 colorimeter calibration matrix. If
|
|
you have access to a spectrometer, the screen and the colorimeter,
|
|
and you just need the calibration for yourself, then make a CCMX as
|
|
it will be slightly more accurate. If you need to make a
|
|
calibration for someone else, then a CCSS for their screen type is
|
|
the way to do it, since it can be used with a different colorimeter
|
|
than your particular instrument.<br>
|
|
<br>
|
|
The instrument manufacturer may supply spectral sample files (see <a
|
|
href="oeminst.html">oeminst</a>).<br>
|
|
<br>
|
|
There is a <a href="ccsss.html">list of contributed</a> <span
|
|
style="font-weight: bold;">ccss</span> (Colorimeter Correction
|
|
Spectral Sample) files for some displays.<br>
|
|
There is a <a href="ccmxs.html">list of contributed</a> <span
|
|

<h3>Usage Details and Discussion</h3>
|
|
<a name="v"></a>The <b>-v</b> flag causes extra information to be
|
|
printed out during chartread operation.<br>
|
|
<br>
|
|
<a name="S"></a><span style="font-weight: bold;">-S</span> By
|
|
default a Colorimeter Correction Matrix (<span style="font-weight:
|
|
bold;">CCMX</span>) will be created from both <span
|
|
style="font-weight: bold;">Colorimeter</span> and <span
|
|
style="font-weight: bold;">Spectrometer</span> readings, which
|
|
allows correction for errors with a particular Colorimeter and
|
|
Display combination. If the <span style="font-weight: bold;">-S</span>
|
|
flag is used, then instead a Colorimeter Calibration Spectral Set (<span
|
|
style="font-weight: bold;">CCSS</span>) file is created from just
|
|
the <span style="font-weight: bold;">Spectrometer</span> readings,
|
|
that allows calibrating any suitable Colorimeter to the Display.<br>
|
|
<br>
|
|
<a name="f"></a><span style="font-weight: bold;">-f <span
|
|
style="font-style: italic;">ref.ti3[,targ.ti3]</span></span> By
|
|
<span style="text-decoration: underline;">default</span> <span
|
|
style="font-weight: bold;">ccxxmake</span> creates a <span
|
|
style="font-weight: bold;">CCMX</span> file by displaying test
|
|
patches on the screen, and then prompting you to measure them
|
|
interactively with the two instruments. An alternative is to create
|
|
a small number of test values using <span style="font-weight:
|
|
bold;">targen</span> suitable for display profiling (or use the <span
|
|
style="font-weight: bold;">ref/ccxx.ti1</span> file provided with
|
|
ArgyllCMS), and then measure them with the two instruments using <span
|
|
style="font-weight: bold;">dispread</span> to create a reference
|
|
and target .ti3 files, and then provide the two files as arguments
|
|
to <span style="font-weight: bold;">ccxxmake -f</span>. Normally
|
|
the reference file will be created using a spectral instrument and
|
|
you will want to use the <span style="font-weight: bold;">-s</span>
|
|
flag with dispread for this. If you want to use a colorimeter as a
|
|
reference instrument, then make sure that it is the first file
|
|
provided to the ccxxmake <span style="font-weight: bold;">-f</span>
|
|
option. The filenames should be concatenated with a <span
|
|
style="font-weight: bold;">","</span> separator without spaces.
|
|
You will also have to supply a display name using the <span
|
|
style="font-weight: bold;">-I</span> option and/or technology
|
|
description using <span style="font-weight: bold;">-T</span>.<br>
|
|
When creating a <span style="font-weight: bold;">CCSS</span> file,
|
|
only spectral readings from the display measured with the reference
|
|
instrument are needed, and a single <span style="font-weight:
|
|
bold;">.ti3</span> file should be provided.<br>
|
|
<br>
|
|
<a name="display"></a>When running on a UNIX based system that used
|
|
the X11 Windowing System, <b>ccxxmake</b> will by default use the
|
|
$DISPLAY environment variable to determine which display and screen
|
|
to read from. This can be overridden by supplying an X11 display
|
|
name to the <span style="font-weight: bold;">-display</span>
|
|
option. Note that if Xinerama is active, you can't select the screen
|
|
using $DISPLAY or -display, you have to select it using the <span
|
|
style="font-weight: bold;">-d</span> parameter.<br>
|
|
<br>
|
|
<a name="d"></a> By default the main display will be the location of
|
|
the test window. If the system has more than one display or screen,
|
|
an alternate display/screen can be selected with the <span
|
|
style="font-weight: bold;">-d</span> parameter. If you invoke <b>ccxxmake</b>
|
|
so as to display the usage information (i.e. "dispcal -?" or
|
|
"dispcal --"), then the discovered displays/screens will be listed.
|
|
Multiple displays may not be listed, if they appear as a single
|
|
display to the operating system (ie. the multi-display support is
|
|
hidden in the video card driver). On UNIX based system that used the
|
|
X11 Windowing System, the <span style="font-weight: bold;">-d</span>
|
|
parameter will override the screen specified by the $DISPLAY or
|
|
parameter.<br>
|
|
<br>
|
|
<a name="dnm"></a>Because of the difficulty cause by TwinView and
|
|
MergedFB in X11 based systems, you can optionally specify a separate
|
|
display number after the display that is going to be used to present
|
|
test patches, for accessing the VideoLUT hardware. This must be
|
|
specified as a single string, e.g. <span style="font-weight: bold;">-d
|
|

<br>
|
|
<a name="p"></a>The <span style="font-weight: bold;">-p</span> flag
|
|
allows measuring in telephoto mode, using instruments that support
|
|
this mode, e.g. the ColorMunki. Telephoto mode is one for taking
|
|
emissive measurements from a distance (ie. telespectometer,
|
|
tele-colorimeter) mode, and typically would be used for measuring
|
|
projector type displays. If a device does not support a specific
|
|
telephoto mode, then the normal emissive mode may be suitable for
|
|
measuring projectors.<br>
|
|
<br>
|
|
<a name="a"></a>The <span style="font-weight: bold;">-a</span> flag
|
|
allows measuring in ambient mode, using instruments that support

this mode. This typically would be used for measuring projector type

|
displays when the light levels reflected from the projection surface
|
|
are very low. Note that this means that the color value will not be
|

quite as accurate, because the effect the projection surface has on

the color is not taken into account.<br>

|
instrument internal calibration matrix suitable for a particular
|
|
display type. The selections available depends on the type and model
|
|
of instrument, and a list of the options for the discovered
|
|
instruments will be shown in the <a href="ArgyllDoc.html#CmdLine">usage</a>
|
|
information. For more details on what particular instruments support
|
|
and how this works, see <a href="instruments.html">Operation of
|
|
particular instruments</a>. Any CCMX created will work on top of
|
|
the selected Display Type, so to be valid, the same Display Type
|
|
must be selected whenever the CCMX is used with this instrument.
|
|
Installed CCMX files will automatically select the appropriate base
|
|
type.<br>
|
|
<br>
|
|
<a name="z"></a>The <b>-z</b> flag allows setting a different
|
|
Display Type for the reference spectral instrument, such as refresh
|
|
or non-refresh type, if it supports it. You may have to use this if
|
|
you are setting a specific base type for the colorimeter using -y,
|
|
and the spectrometer doesn't have this display type.<br>
|
|
<br>
|
|
<a name="P"></a> The <span style="font-weight: bold;">-P</span>
|
|
parameter allows you to position and size the test patch window. By
|
|
default it is places in the center of the screen, and sized
|
|
appropriately for the type of instrument. The <span
|
|
style="font-weight: bold;">ho</span> and <span
|
|
style="font-weight: bold;">vo</span> values govern the horizontal
|
|
and vertical offset respectively. A value of 0.0 positions the
|
|
window to the far left or top of the screen, a value of 0.5
|
|
positions it in the center of the screen (the default), and 1.0
|
|
positions it to the far right or bottom of the screen. If three
|
|
parameters are provided, then the <span style="font-weight: bold;">ss</span>
|
|
parameter is a scale factor for the test window size. A value of 0.5
|
|
for instance, would produce a half sized window. A value of 2.0 will
|
|
produce a double size window. If four parameters are provided, then
|
|
the last two set independent horizontal and vertical scaling
|
|
factors. Note that the ho,vo,ss or ho,vo,hs,vs numbers must be
|
|
specified as a single string (no space between the numbers and the
|
|
comma). For example, to create a double sized test window at the top
|
|
right of the screen, use <span style="font-weight: bold;">-P 1,0,2</span>
|
|
. To create a window twice as wide as high: <span
|
|
style="font-weight: bold;">-P 1,0,2,1</span>.<br>
|
|
<br>
|
|
<a name="F"></a> The <span style="font-weight: bold;">-F</span>
|
|
flag causes the while screen behind the test window to be masked
|
|
with black. This can aid black accuracy when measuring CRT displays
|
|
or projectors.<br>
|
|
<br>
|
|
<a name="n"></a><span style="font-weight: bold;">-n</span> When
|
|
running on a UNIX based system that used the X11 Windowing System, <b>dispcal</b>
|
|
normally selects the override redirect so that the test window will
|
|
appear above any other windows on the display. On some systems this
|
|
can interfere with window manager operation, and the <b>-n</b>
|
|
option turns this behaviour off.<br>
|
|
<br>
|
|
<a name="N"></a><span style="font-weight: bold;">-N</span> Any
|
|
instrument that requires regular calibration will ask for
|
|
calibration on initial start-up. Sometimes this can be awkward if
|
|
the instrument is being mounted in some sort of measuring jig, or
|
|
annoying if several sets of readings are being taken in quick
|
|
succession. The -<span style="font-weight: bold;">N</span>
|
|
suppresses this initial calibration if a valid and not timed out
|
|
previous calibration is recorded in the instrument or on the host
|
|
computer. It is advisable to only use this option on the second and
|
|
subsequent measurements in a single session.<br>

<a name="C"></a> The -<span style="font-weight: bold;">C</span> <span
|
|
style="font-weight: bold;">"command" </span>option allows a
|
|
method of relaying each test value to some other display than that
|
|
on the system running dispcal (for instance, a photo frame, PDA
|
|
screen etc.), by causing the given command to be invoked to the
|
|
shell, with six arguments. The first three arguments are the RGB
|
|
test color as integers in the range 0 to 255, the second three
|
|
parameters are the RGB test color as floating point numbers in the
|
|
range 0.0 to 1.0. The script or tool should relay the given color to
|
|
the screen in some manner (e.g. by generating a raster file of the

arguments are the RGB test color as integers in the range 0 to 255,
|
|
the second three parameters are the RGB test color as floating point

Note that typically this won't make much difference to the resulting

serial communications issues with some systems and cables. <br>
|
|
<br>
|

<a name="D"></a>The <b>-D</b> flag causes communications and other

<a name="T"></a>The <b>-t</b> parameter allows setting of the

display technology type from the available list. You can get a usage
|
|
that includes the list using "ccxxmake -??". This is a required
|
|
parameter, since it conveys information about the refresh type and

|
settling time of the display. If the specific details of the display

the next most generic type. If none of these are applicable, choose

<br>
|
|
<a name="U"></a>The <b>-U</b> parameter allows setting of the user

<h3>Instrument Communications:</h3>
|
|
Unlike the other measurement utilities,<span style="font-weight:
|
|
bold;"> ccxxmake</span> doesn't connect to the instrument until it
|
|
is about to make a measurement. This allows for the possibility of
|
|
using a different instrument for each measurement.<br>
|
|
<br>
|
|
It will display a menu:<span style="font-style: italic;"></span><br>
|
|
<br>
|
|
Press 1 .. 4:<br>
|
|
1) Select an instrument, Currently 1 'usb:/bus4/dev2/ (GretagMacbeth
|
|
i1 Pro)'<br>
|
|
2) Measure test patches with current instrument<br>
|
|
3) [ Compute Colorimeter Correction Matrix & save it ]<br>
|
|
4) Exit<br>
|
|
<br>
|
|
For creating a CCMX there are two measurements to be made, after
|
|
which the correction matrix can be computed and saved. Before each
|
|
measurement, the instrument may need calibrating. For creating a
|
|
CCSS a single measurement is needed.<br>
|
|
<br>
|
|
A spectral measurement using a spectral instrument is always
|
|
needed.<br>
|
|
<br>
|
|
A measurement using the Colorimeter that the correction matrix
|
|
is being created for is needed in the case of creating a CCMX, but <span
|
|
style="font-weight: bold;">not</span> needed when creating a CCSS.<br>
|
|
<br>
|
|
There will be a message before the menu indicating which of the
|
|
measurements has been completed.<br>
|
|
<br>
|
|
<hr style="width: 100%; height: 2px;">
|
|
<h4>Display Setup:</h4>
|
|
Because ccmx/ccss is measuring spectral matching, the exact levels
|
|
of each channel is not important, so the display settings or
|
|
calibration state shouldn't make any difference to the result, as
|
|
long as it is the same for the readings of both instruments.
|
|
Similarly, the number and variety of test patches shouldn't make a
|
|
huge difference, as long as there is at least Red, Green, Blue and
|
|
White test patches.<br>
