History
The "HCFR Colormeter" is the result of a collective development
effort, driven by some passionate persons of HCFR forums...
Everything starts by a forum subject " Build
your own colormeter " in the DIY forum. Alec, Emmanuel,
Georges, Michel (Mlill) and others elaborates the first bases of
reflections.
At the end of 2004, a first draft is outlined, after an intense
reflexion phase with Emmanuel and Michel on theory bases, Francois-Xavier
(Letchoa) founds very interesting sensors at TAOS who were going
to become the eyes of the system. Benoit and Patrice (Ki and Laric)
starts probe design in the meantime FX build alpha version of the
software...
March 2005, things accelerates even more, Michel, Emmanuel, Georges
and FX have completed the whole maths and software architecture,
an initial version of "HCFR" probe is available and ready
for live testing. (was using serial port and PIC 16F876).
Summer 2005, many features are added to software and on probe side
we decide to use USB port, this makes easier powering the sensors
and we also add IR support (emiter) to the probe...
Autumn 2005, the software is now in beta 12, USB probe works marvelously.
Michel intensively works on profiles while Georges join team and
largely improve software design and features. We start looking at
some professional grade building of probe.
In parallel, a beta testers team starts long series of tests and
measurements, Jean-Louis starts working on documentation while David
and Christophe build a superb DVD of test patterns...
Benoit, always full of ideas, add infrared acquisition to proble
(using sensors !), the software is now able to fully aquire remote
command and can drive a DVD player and thus the test patterns DVD.
Winter, 2005, we are ready (almost :D)... The "HCFR Colormeter"
can our hands and go public...
What
it does ? / how does it work?
Our screens, LCD, Plasma, CRT as well as video projectors must
to display colors as accurate as possible. Unfortunately, most did
not have correct initial settings and/or can vary over time...
The "HCFR Colormeter" allows to calibrate a screen (or
projector), this consisting in measuring displayed color patterns.
Then you, users, will have to change settings and parameters on
your devices to try to refine the results to be as close as possible
to the standard of video color reproduction.
The
Software
The "HCFR Colormeter" software is the heart of the system,
it receive the color information from probes, to treat them. It
then allow you to display various curves and the histograms to acheive
calibrating your setup.
The Windows version (New Release 2.1)

The windows version of the software runs on Windows 2000, XP and Vista.
Latest version (v2.1) supports our Probe as well as a "simulated"
one (so you can learn even if you don't yet have a probe). This
latest version also support of some well known third party probes.
- Spyder II
- Spyder III (nouveau dans cette version)
- DTP94
- Gretag EyeOne (Beamer, Display 2, Display LT)
The current version ( v2.1 ) of the software is available for downloading...
This software is distributed under FSF.
GNU GPL license.
Sources code will be available on demand, ask authors.
Software
Version 2.1.0 (~10 Mb)
ColorHCFR is available in French, English and German (Spanish version
should come soon). It also have build-in contextual help.
The Mac OS X version

A mac OS X version of the colorHCFR software is now available.
This version works on mac OS 10.4 and 10.5, on intel and PPC processors.
The current version if v1.1.2, available to download :
ColorHCFR for Mac OS X v1.1.2 (1.7 Mo)
A
discussion forum is available for suggestions, comments and questions.
This version supports the HCFR probe (see below), as well as some well known third party probes :
Attention : if the HCFR probe is not detected by the software or if you enconter problems (especialy with the remote IR control of DVD player), please update your probe with the 5.40 verion of the firmware : >>> HCFR probe firmware v5.40
The update can be done in the colorHCFR software using the "HCFR sensor updater" tool, in the "tools" menu.
With this firmware, you will need to install a new version of the windows driver if you also use it with this OS :
>>> The the windows driver v4.0

HCFR
Probe
A probe is the essential to measure colors. We have build our own
version (similar to tri-stimulus probes). It contains light sensors
we use to measure embeded CPU (PIC) format and transmit data to
application software via USB link.
Our probe also allows to control a DVD Player (or any IR driven
device) this, in addition to pattern DVD will allow to calibrate
your full video chain from player to projector/screen quite easily.
(We strongly recommend you first use software generated patterns,
then use DVD + IR stuff when you are "fluent" with our
software)...
Although we encourage you build our sensor (it gives very good
and reliable results, including sub 30 IRE) it is not mandatory,
starting with version 1.1 we support SpyderII and DTP94 probes.

Here is a link to DIY page on how to build the probe.
"DIY HCFR Probe"
The probe is available in two forms, a single
layer PCB (easy to handle by DIY person) and a more professional
dual layer PCB.
Patterns
DVD (New Release)
We have designed a test pattern DVD that will allow you to calibrate
your full video chain by playing it on you DVD box (can even be
controled by our probe). It includes all patterns needed by software
as well as wome usefull bonus.
So far this DVD is only available in PAL, an NTSC version is on
his way.

People looking for HD-DVD or BD calibration disk,
we strongly encourage to look at this thread on AVS Forum : AVS
