CalMAN V4 et V5 et CalMAN FOR

[SAVY]

Salut Alex_t,

La nouvelle version Calman v5.2 RC2 peut elle maintenant effectuer automatiquement la calibration de JVC X75 ?
Je veux dire de manière complètement autonome, sans gérer soit même les mesures et corrections.
Si oui, ces majs sont elles gratuites et faciles à récupérer ?

Merci et bonnes fêtes à tous.

Salut.

Je n'ai pas le JVC X75 mais le JVC X35. Sur ce modèle seul le gamma et le greyscale sont réglables (sur 11 ou 21 points) en autocalibration . Je dois dire que ça marche plutôt bien (sous certaines conditions, voir plus bas). Pour le CMS des X55/75/95, j'ai pu lire que ce n'est pas si bien que cela, pas à cause de Calman mais plus à cause de JVC qui a un CMS perfectible.

Ceci étant, je vois que tu as aussi un Lumagen Radiance donc je te conseille vivement d'utiliser ce dernier pour calibrer. Le résultat dans ce cas là peut être très très bon sur tous les aspects de la calibration.

Dans tous les cas, pour arriver à une calibration qui tient la route, il faut obligatoirement optimiser le diffuseur via des réglages manuels avant de lancer une auto-calibration. Il y a donc tout un travail à réaliser en amont de l'auto-calibration pour comprendre comment le diffuseur fonctionne et pour trouver les réglages qui permettent d'exploiter son plein potentiel sans que cela nuise à la calibration proprement dite.

En ce qui me concerne, je pense environ 1H pour optimiser mon JVC X35 via ses réglages manuels puis je lance l'auto-calibration via mon Radiance (désormais réalisée par Light Space CMS)

Je te souhaite aussi de bonnes fêtes.

On peut arriver à bien ajuster le CMS des X75 et X95 mais ça demande du travail et je ne pense pas qu'un autocal puisse y arriver.

La bonne méthode consiste à sélectionner le gamut le plus proche de la cible (c'est la méthode de base).
Ensuite il faut calibrer non pas sur des sat à 100% mais à 75%.
Il faut pouvoir avoir une lecture du gamut avec des paliers. En général on mesure à 25, 50, 75 et 100%
L'objectif est de trouver le point pour lequel le DeltaE simultané à 25, 50 et 75 est au plus bas.
Ca demande donc du temps, des va et viens, des compromis et de la stratégie ... les Autocal Calman ou CP ne peuvent pas fournir cette démarche.

[alex_t]

En fait le problème de l'autocal de Calman et Chromapure est qu'il repose sur une approche empirique, comme le ferait un humain mais avec l'intelligence et l'expérience en moins : le logiciel mesure et si c'est hors tolérance, le logiciel corrige systématiquement sans vérifier l'impact de la correction sur tous les autres paramètres.

From Ted on avsforum

Hello, I'm sorry but my website is not ready 100% but you will have a complete idea how the disk's Full Automated (for LightSpace) / Semi-Automated (for CalMAN/ChromaPure) works when you will read the following instructions:

Ted's LightSpace CMS Calibration Disk covers the 3 major software that pro/home calibratiors are using: LightSpace - CalMAN - ChromaPure.

For LightSpace the intergration with the Disk is Fully Automated, look how it works:

Intergration of Ted’s LightSpace CMS Calibration Disk with LightSpace Software for Automated Quick Profiling /10-Point Cube / 17-Point Cube Profilings without user prompt, How is this possible?

LightSpace is using 2 modes to display and measure the Patches of your SelecTED Cube Size:

Closed Loop Mode: Where the probe dictates the timings per patch, with bright patches measured much faster, darker ones need more time to be measured,

So with Closed Loop Mode you can use the LightSpace Internal Pattern Generator using you Notebook HDMI Output (with proper setup) or to use Lumagen Radiance Series as External Hardware Pattern Generator.

DIP mode (Display Independent Profiling): This mode uses a fixed time of displaying each color patch. Since the LightSpace is using the method of measuring only one time each color point, the patch sequence is fixed for each Cube Size, So My Disk is based to this fixed color point (patch) measuring order...

Example of DIP Mode:



If you select the 5 sec DIP mode, each patch isdisplayed for exact 5 sec before it goes to the next color. LightSpace has a fixed internal delay of 0.5 sec (500ms) which gives command to your meter to read each patch 0.5sec after it’s been displayed via Lumagen or via HDMI Out or via my Disk.

If you want to add some extra delay time before each Patch Measurement, LightSpace has add a Selectable bar you can add any additional time you want, and LightSpace adds your extra time selection to the 0.5sec fixed internal delay.



Example: If you select Extra Delay Time of 0.5sec, then the total delay you will have in total will be 1.0 sec (1000ms) before any meter read.

(This is something I requested from LightIlusion to Add it as a feature @ December 2012, to help Plasma Profilings for more stable measurements)

Plasma displays can benefit from adding an Extra Delay Time before each measurement; it's useful for the panel to have more stable presentation of each pattern. How to Find Out which DIP mode can be used for your display/meter?

To find out which DIP Chapter of my disk isrequiredfor your current display settings / meter settings, you have to use the Meter Time per Patch Finder Chapter of my disk which it displays the darkest colors of the selected LUT resolution and you need to measure these patches to find out which is the correct DIP mode Chapter you will need for your display profiling.

As we know, meters require more time to measure a low luminance color (Dark Patches) and also they can read faster a brighter color patch (With more Luminance). The time it takes for your meter to read the Darkest Color Patches of your selecTED LUT Size is something that you need to take some measurements to find out the max time in xxx ms that will be required.



LightSpace has a feature called Measure & Log.

By Selecting this, you will be prompt to enter a File Name, for Example you can type ''5% Red'' and after clicking ok, the LightSpace will take continuous readingsof the pattern you are displaying, as long time as you want, to stop this , press ‘’Stop Measurement’’...

After doing that, a ‘5% Red.cvs’’ file will be created and you will be able to open it with Excel to see the xyY Readings and the time it took for your meter to read this patch.

(This Measured & Log Mode is something I requested from LightIllusion to Add as a feature @ December 2012, while I was trying to find out a way to use the DIP Mode to by synced with My Disk)

This is an example of the CVS file Data contents:



Here you can see the exact time it took to read the 5% Red of my KURO, with my iD3 (I have selected 1.5sec Intergration time).

This is a good way to find out and set your Meter Intergration Time, by checking the repeatability of any patch, and compare 2-3 different Intergration time settings (1sec. 1.25sec, 1.50sec…etc..) to find out which setting have more stable and repeatable xyY measurements.

IMPORTANT DETAIL: Enabling Average Low Light Measurements IS NOT RECOMMENDED TO BE USED WITH MY DISK! Avoid this Low Average Feature because the meter is reading more that one time the same patch (probably it will take 15-40 sec to return a single xyY number)

After you have decided about your Meter Settings, by selecting the Intergration Time and the Display Type (for colorimeters only), you have to spend a few minutes to take some measurements using my Disk’s Meter Time per Patch Finder Chapter.

Example: By Selecting the 17-Point Cube Time per Patch Finder Chapter, you will see this introduction screen..



Here you are able to see the Pattern Order Sequence.

Before each displayed pattern there a notification screen which displays what pattern it will be displayed… so when you will see that 5% Red Info Screen, click Measure and Log... and enter ‘5% Red’ as a file name, to collect data about any measured color.



You have to do this for all the 5% RGBCMY+Gray+Black Patchs to examine later which is the longest meter read with your Current Display Settings.

It’s very important step to keep the Disk-Software Synced during the whole 17-Point Profiling Time.



After you have completed all the required measurements (you will have saved a similar list of measurement files like this one), you have to open each one *.CVS Data

File to find the longest in xxx.ms time it took from you meter to read it.

For example if your Longest in time read is4200ms,add +500ms to this (because LightSpace adds that 500ms internal delay before each reading)…your total max measuring time will be 4700ms… so you will have to use the 5sec DIP mode for your 17-Point Profiling using my Disk.

If you need to add extra additional time of about 1sec, then you can select that from the probe setup window and later select the 6sec DIP mode 17-Point Profiling. (Because 4200ms+500ms+1000ms will need 5700ms).

Be sure you have disabled any Screen Protection, Auto Stand-by mode or your Blu-Ray Player ‘Screen Saver Mode’ during before any Profiling Run.

How the Sync of Ted’s LightSpace CMS Calibration Disk with LightSpace CMS Software Works without user prompt for 17-Point Cube Profilings (4.913 Color Points) is working?

To sync the Ted's LightSpace CMS Calibration Disk played from your Blu-Ray Player with the software it requires ONLY ONE Synced Click from your Notebook Mouse.

My Disk’s DIP Mode Chapters are Starting with a 5 Sec of Chapter Announcement like this one:

(You can check the total chapter time here or from LightSpace software before starting the profiling measurements.)



...A 5sec 'Old Film Like' Countdown with Start,likethis one:



And when you see the last frame.....



You have to click 'OK' the LightSpace Start Measurements Confirmation Window



Click 'OK' to start the measurements or press ‘Enter Key’ from your keyboard (I prefer this for perfect timing)

For the LightSpace users, all chapters are automated with Ted's LightSpace CMS Calibration Disk.

The video below shows the chapter that Klein K-10Ausers can use since it's their meter is so fast; they can use 1 sec per patch only!.

http://youtu.be/fkZSlNFUp7w"]http://youtu.be/fkZSlNFUp7w

* Change the resolution to 1080p and run it at fullscreen.

With this method id3 users can use DIP Mode Chapter with 4 or 5 or 6 sec per Color Patch to perform a 10-Point Cube Calibration in total time between 1 hour - 1hour 40 minutes max, this is something it depends on user display and meter settings.



The LightSpace has a PercentageBar you are able to see your progress...

There is not any other user prompt till the end, After the last Color Patch is being measured, the LightSpace is saving that sesssion of measurements automatically and the same time you will see that image at your TV screen:



CalMAN use with Ted's LightSpace CMS Calibration Disk

The CalMAN Chapters are created based to the exact same pattern order sequence that CalMAN requests them.

The RGB Triplets of each color patch are exact the same as CalMAN Internal Engine works/expects.

None of my disk patterns has a small lettering indicator of which pattern you are viewing; inside or outside the pattern area. (like other calibration disks)

There is a small 2 sec Pattern Info Screen announcement before any Pattern... I have placed the Pattern Info (for example: 100% Red, 30% Gray etc.) at the right side of the screen and not at the center.....

I did that because at the center of your screen you have placed your meter

After the small pattern announcement, you will see the pure pattern, like it was generated from an External Pattern Generator wink.gif

For example to run a 21-Step Grayscale Set @ CalMAN the Pattern AutoAdvance (Or use the provided workflows I'm hooking up my disk users) and select the 21-Step CalMAN Chapter of the disk.

After that each pattern will be displayed for 10 sec from the disk, you will have to click 21 times the Single Read button of CalMAN. When i was using my id3, it worked very good, I used 1 sec delay also before each meter read.

Unfortunately for C6 (which is extra slow @ low end, it will require to pause the 5-10% patches of the disk, but this has to do with the display you are measuring, for LCD/LED maybe will not required)

I have decide 10sec for each patch because these CalMAN/ChromaPure Chapters are mainly for verification purpose, this means a quick read per color, but if someone needs to perform a 1D LUT Calibration, he can do this by using it's pause button.

No need for IR Controlling, The Chapter for CalMAN or ChromaPure are Auto-Changing every 10 sec. to the next required pattern.

For Example to perform a Color Checker Classic Run you have to press 24 mouse clicks for the meter to read; using my workflow below:



I have uploadTED an example video to show how it works.

Each Chapter starts with 5 sec of Chapter Information Details, and after that there is a 2sec pattern announcement to prepare you of what you will measure and 1 sec of black frame and then 10sec for the color patch, if you like you can use your player remote next button to go faster to the next patch or leave it without user prompt to finish the total pattern displaying.

http://youtu.be/3dOg7HafBBw"]http://youtu.be/3dOg7HafBBw

* Change the resolution to 1080p and run it at fullscreen.

ChromaPure use with Ted's LightSpace CMS Calibration Disk

Same as explained at CalMAN infos above.

Each ChromaPure Chapter starts with a 5 sec of Chapter Information Details, and after that there is a 2 sec pattern info announcement before each color patch to prepare you of what you will measure; after that pattern info announcement there is 1 sec of black frame and then 10 sec for the color patch, if you like you can use your player remote next button to go faster to the next color patch.

RGB Triplets from each Color Patch are coming from the exact RGB Triplets that ChromaPure Color Engine Calculations are based.

Each ChromaPure Chapter has the exact pattern order as ChromaPure request it.

Video Example:

Verify Calibration Tools - ChromaPure: 4-Step Amplitude

https://www.youtube.com/watch?v=fbvty56uTIA

* Change the resolution to 1080p and run it at fullscreen.

You can say that CalMAN / ChromaPure intergration with my disk is Semi-automated, since the user will have only to simply perform some single measurements clicks.

Ted's LightSpace calibration disk MP4 sampler

http://www.avsforum.com/t/1454804/teds- ... t_24323548

Ted's LightSpace CMS Calibration Disk - MP4/MKV Media Files Version Sampler

Users they are sking me if the Media Files Version of my Disk is compatible with their players, so I'm uploading here for all a Test Chapter in both formats for those who need to check.

I have include 2 versions of MP4/MKV Files for each CalMAN/ChromaPure or LightSpace Meter Setup Chapters.

One version of the files has 1 File per Chapter and it's encoded with included Chapter Marks informations, if your device is supporting Chapter Marks for MP4/MKV Files then you will be able to change the Chapters using your player remote control left-right buttons, but it has to do with the device you are using, if it supports chapters on MP4 or MKV files or if it handles them as a single file without Chapters.

These files are located in CalMAN/ChromaPure or LightSpace Meter Setup Folders.

The other version of that files are located in subfolders of these directories and it's the splited version of color patches at separate files.

For example, inside the 11-Step Grayscale file folder you will find 11 files; each file per color patch (named as 01. 0% Black , 02. 10% Grey, 03. 20% Gray etc.) and your media player will auto advanced to the next color patch since these files are located in the same folder, but you will able to navigate thou the previous/next pattern using your player remote next-previous buttons.

The loading delay time between each file is expected to be at ~0.1-0.5s range because the file format stays the same.

Bonjour A Tous,

Je viens de m'équiper d'un DLA-X700 et je me demande quel est Le meilleur soft pour Le calibrer : calman 5.3 ou chromapure 2.5 ? A ce jour je dispose de colorfacts 6 et des sondes spider 2 et eye-one pro dois je aussi envisager l'achat d'une sonde C6 ou I7 display 3 pro ou la version de base x-rite display pro est elle suffisante ?

Merci de vos éclaircissements ...

EG

[jacko]

Calman intégrera très probablement un autocal pour la génération Xx00.
La C6 est dédiée Calman.
Cependant tu peux envisager une Display 3 OEM que tu pourra profiler à chaque calibrage avec la Eye 1 Pro, à condition que la sonde soit vérifiée et calibrée.

Tu peux garder ta Spyder pour calibrer les TV ... sinon poubelle !

[emilegold]

Merci jacko de ta réponse..

Ou puis-je envoyer mon eye one pro en vérification / recalibration en France et à quel cout et à qu'elle fréquence selon toi

Nous nous en servons dans mon entreprise pour calibrer les 6 écrans nec tous les 2 mois et très rarement pour étalonner notre appareil photo canon et notre imprimante epson...

J'ai regardé la différence de prix entre calman et chromapure c'est quand meme du simple au triple pour un pro !!! y a t'il une remise sur le prix quand on a déjà colorfacts pour calman, comme le propose chromapure ?

EG

[jacko]

Salut,

Il y a des programmes d'upgrade aussi bien chez Chromapure que Calman lorsqu'on vient d'une licence tiers.

Pour un usage simple et peu coûteux je te recommande Chromapure.

Calman a l'avantage d'ajouter des outils d'autocalibrage et propose la gestion de 3D LUT sur certains produits.

Pour faire vérifier et étalonner la i1 pro tu peux contacter X-Rite France http://www.xrite.fr/
Il t'orienteront si besoin vers un centre en Europe.

Ajouter une D3 dans ta liste matériel va te changer la vie ! Le calibrage des NEC se fera à une vitesse hallucinante.

[Thebe]

Bonjour,

même si j'ai vu quelques références à cette nouvelle version (5.3), elle est maintenant disponible (depuis le 12 mars) sur le site de Calman :

Jacko j'ai besoin de ton aide,

J'ai commencé à calibrer mon JVC X700 mais je me heurte à un problème : si je règle mes couleurs primaires et secondaires pour respecter leur saturation à 100% (c'est la norme mais aussi la seule option dans le CMS JVC) alors les valeurs mesurées à 25 / 50 et 75 % de saturation sont à l'ouest... Dans un post précédent tu recommandais de prendre les valeurs moyennes comment fais tu en détail ,car j'ai fais un essais avec 75% de saturation (beaucoup plus simple à calibrer qu'à 100%) j'ai des valeurs totalement opposées à celle de la saturation 100% !!!

Merci de tes lumières.

EG

[jacko]

Calibrer un gamut sur la base des saturations à 100% est l'erreur à ne pas commettre.

Le plus important est d'ajuster les intermédiaires afin de réduire au maximum les DeltaE.
Ainsi le CIE 3D aura moins d'erreur.

4 possibilités.

La plus simple et celle recommandé par Tom Huffman : calibrer à 75%.

La plus complexe : mesurer à 25, 50 et 75. Ajuster les paramètres un a un et par composante. Mesurer de nouveau à 25, 50, 75 valider la valeur pour laquelle le DeltaE des intermédiaire présente les valeurs les plus basses ou la plus faible moyenne.
Refaire l'opération par paramètre et par composante.
Cela équivaut à 18 calibrages.

La plus coûteuse : ajouter un CMS 3D LUT (Radiance par exemple) piloté par le bon logiciel, LightSpace étant le plus performant de par son mode opératoire.

La dernière ... faire appel à un calibreur qui a le matos et l'expérience.

[emilegold]

Jacko,

Merci de ton aide précieuse. L'ingénieur que je suis veux comprendre comment tout cela fonctionne parfaitement, c'est pour cela que j'y consacre du temps...

J'ai fais un test avec une calibration à 100% et une à 75%, dans le premier les couleurs sont saturées - dans le second elles sont plus pales . Ce qui semble parfaitement normal. La solution passe donc par des compromis ou un Radiance 2XXX (trop cher pour moi)...

Je vais faire des tests pour avoir un deltaE le plus bas possible a 25, 50, 75 et 100 si je comprends bien... C'est un travail de longue haleine et de patience infinie...

Pour le gamma que me recommandes tu pour ajuster la courbe des W,R,G,B pour coller à mon gamma de référence (j'ai opté pour le BT) car j'ai choisis 32 points et cela ne semble par super probant hormis pour le blanc...

Encore merci de tes conseils.
