Fork of HCFR Started - What's needed? - Page 50

I've not tested whether this works or not.



edit: The current version only allow building a spectral sample in view images mode, I'll upload fixed version shortly. I did one test using the HCFR built sample vs. the previously linked Dell plasma_family and results were nearly identical.

HCFR Spectral sample calibration vs. Plasma_Family EDR calibration dE ~0.8 between the two


Note: very slight advantage (50% and above) to the HCFR built one which was done with the i1pro 2 in hires mode.

I ran the create spectral sample and ended up with these 2 files

spectral.zip 11k .zip file

I only see one file, 151fd.ccss and it's got the right info in it. Did you use DVD patterns or automatic "view images" ?

I used the view files. the zip file above also has a .cal file in it. its in code so I cannot tell what is in it. the ccss file I can read.

Any chance someone in here with an LED TV (like Samsung ES8000) could create a spectral sample and compare against the default LED sample?

well I'm not seeing the other file but no matter, you can use the .ccss you made by adding it to the application data\color folder.

I've uploaded a new build to sourceforge that allows creation of spectral sample files using the manual (DVD) image generator option.

You need to find the datacolor driver (dll) for this probe and put it into the HCFR directory, I'm not sure where this driver can be obtained from but one of the spyder3express install packages should install one.


edit: CVSpyder.dll from c:\Program Files\Datacolor\Spyder3Express\Support is the file you want.

Zoyd ,found a bug with latest build.

When using HDTV709 75% in preference and you try clicking on any of your greyscale ire run,instead of showing the RGB bars and bullseye ,it only shows a yellow bar with the word luminance.

Now when I switch back to HDTV709 regular.The RGB bars and bullseye show up just fine.Thanks.

the .cal file was created the same time as the .ccss file.

.i1p_321118.zip 8k .zip file

Anyway, thanks for all you have done, if I can be of any help let me know.

got it, thanks. will be fixed in next build later today.

Hello once again and thank you for replying, i downloaded spyder3express because my spyder 3 didn't have a support file in it. i copied CVSpyder.dll to my hcfr directory (downloaded from http://sourceforge.net/projects/zoyd000.u/files/downloads/) and i have the same errors, the first one occurs when i press file> then select DVD manual, i press Next and then "Incorrect Driver - Starting communications with the meter failed with severe error.Argyll Error". I click ok,then select Spyder 3 and press finish. Then after i press the run button i get " Spyder3.dll returned an error during initialization", i press ok on this one and then get another one "Error during sensor Initialisation". I thought i should move the spyder3.dll and CVSpyder.dll to the drivers folder of the hcfr install directory but that didn't work either.

Install spyder3express and make sure the probe works with that software. As part of that install you should follow directions to install the probe drivers. Then try HCFR again.

Zoyd or anyone,

I calibrated my Panny GT30 with the default ITU/1886 setting (2.22) in advance preference and when I check my gamma Y readings compared to the gamma,saturation excel spreadsheet it shows that my gamma is low.

But then when I click the "Dispaly gamma" in advance and compare with the excel spreadsheet it is Spot on.

Also, if I click "Dispay Gamma with black compensation" it requires me to click down one notch on the the brightness control to line up perfectly with the excel spread sheet.

So my question is, which one do I set as my preference and trust to set my gamma.?

Thanks amigo's...

I assume you mean my GCD spreadsheet right? The Y target values in the spreadsheet are calculated using the exact, non-rounded stimulus levels of the patterns and will be slightly different than what HCFR calculates based on integer values. Typical differences for 10%-90% levels are:

0.81% 0.92% 0.96% 0.99% 1.01% -0.69% -0.44% -0.26% -0.12%

The maximum error at 50% stimulus in gamma is 0.02 so these can be ignored, so just use what HCFR is telling you.

Nope,the other excel with saturation,gamut,brightness.

I just wasn't sure if I needed to change me preset to display gamma rather than the default ITU/886.

If you want to calibrate to BT.1886 targets, set it to BT.1886. If you want to calibrate to a flat display gamma, set it to display gamma. simple as that.

Uploaded a new build:

-fixed issue to prevent going into target mode (RGB balance changes to luminance) on the grayscale page
-added an average dE display in the measurements title bar

Is 2.22 the default (I mean the desirable) setting for ITU/1886 or just a personal prefered setting as it can be 2.3 or 2.4?

BT.1886 does not have a single gamma value like the other options so it doesn't matter what you enter into the box, I will grey that out in a future version. If you choose this option the value of gamma is a little different at each stimulus level and it's calculated automatically based on your white and black level measurements.

Thanks Zoyd..

Adding the average dE display in the measurement title bar was a great addition.I use to pull out the trusty calculator to figure this out..Thanks again for all your effort.

Thank you zoyd, I had seen it what you explain but the question that arises is that I can influence my white and black level measurements (0% and 100%) with gamma controls of my display and then the gamma value for each stimulus is different. For instance I had a Mitsu HC7000 projector with 3 controls for gamma (High, Medium, Low) and for each RGB Color. If I lower (or upper) my gamma control for Low range in order to achieve the calculated gamma for 10% and 20% stimulus I'm also affecting 0% stimulus, and I'm changing the calculated gamma at the same time.
What I mean is that white and black levels are not absolute values. Is that true?

Well, I think you should choose a fixed white level to target and then adjust contrast to hit that target whenever you change the gamma control. That will define an absolute peak white for you at whatever level your room and viewing comfort dictate. On the low end you should always try to minimize 0% stimulus as far as possible for best contrast. Probably a BT.1886 curve can only be nicely matched using a 10pt gamma control and if you don't have that you'll have to find a compromise.

Zoyd,forgive my ignorance....If I just want to achieve a flat gamma since I only have a 2pt adjustment,do I choose display gamma or display gamma with black compensation in preference..Thanks

You can't adjust the shape of the gamma curve with a 2-pt. control. You can pick different fitting functions but that's not changing your gamma, that's just changing how it is plotted. In your case, without a 10 pt. control, I would set it on display gamma and choose whatever gamma preset (low, mid, high etc, if you have them) gives an average gamma equal to your target gamma number, between 2.2 - 2.4

Thank you very much i re-installed hcfr and spyder 3,copied spyder3.dll to the hcfr install directory and now everything works fine.

Great...Thank you.

+1 That would be so helpful if I could get my hands on a spectral sample from the ES8000!

I read that you need old version of spyder3.dll (from spyder3expres 3.0.1 or older) to get it work with HCFR, seems that you have it and I can´t find it, so please could you upload it (just that spyder3.dll file) ?
I don´t need that but few others would be grateful to get Spyder3 work with HCFR.

Note that ArgyllCMS drivers support the Spyder instruments (Spyder 2/3/4) without needing spyder3.dll

Hi Graeme,

There are spyder2en.exe spyder4en.exe executables for those meters, how does one enable a spyder3?
