Version 2.2.10 is now available for download.

ChromaPure 2.2.10 Release Notes

This release provides some critical updates to the auto-calibration module. No other changes have been made.

Version 2.2.9 is now available for download.

ChromaPure 2.2.9 Release Notes

This release adds three new modes to PRO meters, including:

• DLP Rear Projection
• LED Front Projector-Lens
• LED Front Projector-Screen

The DLP Rear Projection Mode can be added to existing licenses without recalibration (contact ChromaPure Technical Support). The LED Projection Modes can only be added to existing licenses during recalibration.

We have also improved the read performance of the Display 3 colorimeter in Front Projection-Lens mode.

AccuPel Professional is now shipping. This version includes 70 motion patterns that are ideally suited for video engineers, testers, and reviewers. It is also an invaluable tool for professional calibrators who wish to test a display's deinterlacing and/or motion resolution.

The AccuPel DVG-5000 Professional MSRP is $1499. Deluxe users may upgrade for $200. For details on AccuPel Professional, see our AccuPel page.

Version 2.2.8 is now available for download.

ChromaPure 2.2.8 Release Notes

There is only one change in this build. After additional testing and customer comments, we have further refined support for the i1 Display Pro III colorimeter. This version offers a better compromise between speed and low-light repeatability. There are two things to keep in mind about this version.

• Single readings below 1 cd/m2 outside of auto-cal will be very slow. This is normal. All other readings should be as fast or faster than in 2.2.7
• Do not use measurement smoothing with the Display 3 colorimeter. It will only slow readings down without improving repeatability. It still may be useful with other color analyzers.

Version 2.2.7 is now available for download.

ChromaPure 2.2.7 Release Notes

New Features

• PRO meters now include corrections for LG LED and LCD displays.
• In consultation with X-Rite, we made an adjustment to our i1 Display Pro III support that provides significantly better repeatability at low light levels.
• The Color Management module now includes a CIE chart.
• The Advanced Color Management module now includes support for the Lumagen Radiance as a signal generator.
• When initializing the JETI 1211 spectroradiometer, the application now automatically measures and sets the cycle rate of the target display.

Bug Fixes

• The AccuPel signal generator would lose default settings after working in the Advanced Color Management module. This has been fixed.
• Connection to the selected meter would be lost when cancelling out of the Options module. This has been fixed.
• If the user neglected to initialize a meter before selecting auto-advance, the system would become unstable when taking grayscale readings.
• The system allowed users to select a null value from the signal generator drop-down. This has been fixed.

Version 2.2.5 is now available for download.

ChromaPure 2.2.5 Release Notes

The resolution of problems with the PRO corrections in the previous release revealed another problem that was previously masked by the error 2.2.4 fixed. We had intentionally reduced the speed of the Display 3 readings below 10 cd/m2 to improve repeatability. However, doing do disabled the PRO corrections for those readings (continuous measurements, single measurements above 10 cd/m2, and all measurements with meters other than the Display 3 were unaffected). This problem has been fixed.

Version 2.2.4 is now available for download.

ChromaPure 2.2.4 Release Notes

This release includes the following:

• Support for the Photo Research PR-650 in ChromaPure Professional.
• During routine testing we found a bug that could reduce the accuracy of measurements of PRO meters. This has been fixed.

Version 2.2.3 is now available for download.

ChromaPure 2.2.3 Release Notes

This release includes the following new features:

• Support for the new X-Rite i1 Display Pro III colorimeter.
• ChromaPure's AccuPel video test pattern generator support now includes all SD and HD European formats.
• We improved the performance for the DVDO Duo when using auto-calibrate.
• We have enhanced support for the JETI 1211 spectroradiometer.

Version 2.2 is now available for download.

ChromaPure 2.2 Release Notes

This release includes the following new features:

• Auto-Calibrate. This is an optional add-on that works with a DVDO Duo or Lumagen Radiance external processor. After selecting some basic options, it provides a comprehensive calibration with no user input. Auto-Calibrate is available to ChromaPure Standard users for $149. It is free for ChromaPure Professional users. ChromaPure Professional users should contact user support for a license upgrade to enable this option.
• QuickReports. This new feature allows users to quickly and easily generate basic reports within the application that summarize data in the Pre/Post-Grayscale and Pre/Post Color Gamut modules. These single-page reports can be exported as PDF, Word, or as an image file.
• 5% measurement increments have been added to the White Balance and Raw Data modules.
• We are offering a new version of ChromaPure, ChromaPure Plus. The MSRP for this version is $300. It adds support for the AccuPel video test pattern generators.

Version 2.1.2 is now available for download. This is a maintenance release to correct a bug introduced in 2.1.1 that resulted in corrupted data when using export/import.

Version 2.1.1 is now available for download. This is a maintenance release to address some issues discovered in 2.1.

2.1.1 Release Notes

• When using 75% Rec. 709 in the Color Management module, the application used 100% saturation as a target for green. This has been corrected.
• When importing data saved from a 5% grayscale session, the luminance at 85% was incorrect. This has been corrected.
• When importing a session that used meter corrections (either application-level corrections or PRO meter corrections), the user could not take new measurements. This has been fixed.
• When importing a session that used meter corrections (either application-level corrections or PRO meter corrections), the data did not reflect the corrected readings. This has been fixed.
• Test patterns for the Lumagen Radiance are now forced into the Adjustable mode.

Version 2.1 is now available for download. This release is free for all 2.0 users. 1.x users may upgrade for $59.95. Those with PRO meters will need new license files. I will be issuing these in the next day or two. In the meantime, those with PRO meters may use the program, but without the built-in corrections. Uninstall the previous version before installing 2.1. When you start 2.1 for the first time, it should pick up your existing license file.

2.1 Release Notes

New Features

ChromaPure 2.1 will be released in just a few days. Check back here for a download link.

Check out the Demos page to see live examples of many of the new features in action.

• The Advanced Color Management module has been completely redesigned with significant new functionality, including:
  • All data is saved.
  • All data may be exported and shared as charts, raw xyY and dE, or in an Advanced Color Management Report.
  • New charts showing dE and luminance performance at all points.
  • The ability to use information from this module to calibrate to 75% Rec. 709 in the standard Color Management module.
• The method for training a field meter to match the response of a reference meter has been completely redesigned from using linear offsets to a four-color matrix calculation. This significantly improves the accuracy of readings in the Advanced Color Management module and will slightly improve accuracy throughout. This new method applies to both the Meter Offset (renamed Meter Correction) module and PRO meters (new licenses will need to be issued for these).
• The signal generator feature has been completely redesigned with sigificant new functionality, including:
  • Port settings for serial devices are now sticky per device chosen.
  • Users may now setup a signal generator, begin work, and then change the parameters of the signal generator without closing and restarting the application.
  • When you setup a signal generator, close the application and then restart, ChromaPure remembers your generator settings and automatically applies them. You can begin work immediately.
  • The Quantum Data 780/Sencore MP500 test pattern generators now support user-selectable 100% and 75% patterns and RGB/YCbCr color spaces. The Lumagen Radiance now also supports user-selectable 100% and 75% patterns.
• The Pre/Post-Calibration Grayscale modules now include percentage output information and an option to display gamma data in a line chart or curve chart.
• The Data Conversions module now includes a color difference section in which the user can enter reference and test colors in xyY and see dE in all of the four major dE methods and percentage errors in hue, saturation, and lightness.
• The application now uses a rolling average to improve consistency for low-light readings when using the Hubble colorimeter.
• White and black pluge patterns have been added to the built-in test patterns.
• The Gamma module now supports readings at all 5% increments.
• The Lumens Calculator has been completely redesigned. You can now enter information about lumens, lux, foot lamberts, or cd/m2, provide information about the screen, and then the module calculates results in lumens, lux, foot lamberts, and cd/m2.
• ChromaPure now supports the AccuPel DVG-5000 video test signal generator.

Cosmetic Enhancements

• The appearance of the White Balance module has been significantly enhanced.

This release offers a few bug fixes identified in 1.3. It can be downloaded here. 1.2.1 users who want to use this build should contact user support for an updated license file.

Bug Fixes

• The meter mode drop-down incorrectly displayed Generic LCD as the default choice when CRT was the actual default. This has been fixed.
• The DTP-94 meter used fL when cd/m2 was selected as the default luminance.
• The Pre and Post-Calibration Grayscale modules displayed grayed-out selections until activated by auto-advance. This prevented the user from selecting any desired level until all readings had been taken. The grayscale levels are no longer initially grayed out.
• The Settings Report was broken. It has been fixed.

Known issues

• Some international character sets cause problems requiring the user to select U.S. English in the Windows Control Panel.
• The internal test patterns initially appear in duplicate. Just close the unnecessary window to proceed.

New Features

• Support for Chroma 5 PRO colorimeter. Note: Only customers who wish to use the Chroma 5 PRO colorimeter should upgrade. The remaining feature set is the same as 1.2.
• Help more closely integrated into system

New Features

• Support for automation with the Accupel (HDG-3000/HDG-4000) external signal generator
• Support for automation with the PC's video card
• Support for integrated reporting (Excel no longer required)
• Support for the Klein K-10 non-contact professional colorimeter
• Support for 15% and 95% levels in gamma module for use with JVC projectors
• Support for 64-bit operating systems

Cosmetic Enhancements

Grayscale and Color Gamut modules now display the dE method selected in the Options module.

Bug Fixes

• We have fixed an issue that arose when changing Options or importing a session file. Previously, the new data would only appear after closing and then reopening a module. Now the data automatically refreshes.
• We have removed the .cal session file format and replaced it with a .calx XML format instead, which is more reliable, scalable, and can be opened by the user as a text file.

Known Issues

We are still working on providing 64-bit support for the DTP94 colorimeter.

Existing customers are enitled to a free upgrade and will be provided with download instructions

Cosmetic Changes

• Added icons along the top of the window

Bug-fixes

• Fixed problems with the Chroma 5 colorimeter's CRT mode.
• Fixed a problem in which quickly moving between open modules would cause a crash.
• Fixed an issue that arose when reading very low light levels in which the values could not be interpreted by the gamma chart resulting in an unhandled exception.

New Features

• Added support for Excel 2007 (for reporting).
• Added support for the DTP-94 colorimeter.
• Added a feature that prevents system instability that may arise when users would attempt to take readings in one module when the continuous mode was still enabled in another module.
• Added an auto-save and data recovery feature to enhance data integrity. When you exit ChromaPure© normally, you are asked if you first want to save the calibration session.* Also, the system will now auto-save the session data every 2 minutes. If the calibration session is unexpectedly interrupted due to loss of power or a system freeze or shutdown, upon re-starting ChromaPure© the user is asked whether he or she wishes to load the most recently saved data.
• Added an XML file format to session data export. The advantage of this over the binary .cal session files, which are retained, is that you can open the files and read them in a web browser.
• Added support for the CIE2000 color difference formula
• Added an optional 5% reading in the Gamma module. This can help with getting shadow detail just right, especially with a display or processor that offers point-by-point gamma adjustments.
• Application modules now have scroll bars when all the controls do not fit in the window.
• ChromaPure© no longer allows multiple instances of the application to be running.

* The binary session files saved with older versions of ChromaPure may no longer work.
