Version 2.4.1 is now available for download

ChromaPure 2.4.1 Release Notes

New Features

• We have added support for BT.1886 gamma transfer function to the Gamma module. You must enter the 100% white and video black data in the Options panel to get a accurate gamma response.
• We have added an Excel-based report to the Color Checker module, including support for pre and post-calibration data.
• We have added support for selectable gamma (including BT.1886) to the Color Checker module.
• We have added support for the 4K Quantum Data 804a signal generator.

Improvements

• We have simplified the test pattern generation/measurement functions in the Color Checker module. One click now displays a test pattern and takes a measurement.
• We have added support for 75% stimulus test patterns to both the Lumagen auto-calibrate feature and the Lumagen Video Processor Control Toolbar.
• We have added a Gamma Factor selector to the Lumagen Video Processor Control Toolbar to allow for easy across-the-board adjustments of gamma.
• We have added the ability to use Auto-Advance when beginning measurements at 10% or 20% stimulus in the Pre/Post-Calibration Grayscale module.
• Repeatability and speed with low-light measurements when using the Display 3 colorimeter has been further improved.
• We have added adjustable increments to the Video Processor Control Toolbar to allow for both smaller and larger adjustment increments.
• We have adjusted the layout of the auto-calibrate module to fix problems with selectable options being cut off and rendered invisible.
• We have added support for custom colors to the Quantum Data 780 and 804a signal generators. Both signal generators can now be used in the Advanced Color Management, Color Checker, and Color Management (when selecting the 75% of Rec. 709 gamut) modules.
• We have enabled a manual mode on the JETI 1211 reference spectroradiometer. This allows the user to manually select a desired refresh rate of the target display. However, for most applications we recommend that you continue to use the sync mode.
• We have added additional test patterns to the AccuPel Signal Generator Toolbar.
• We have added a Reset button to the Raw Data module that allows users to clear out data without having to close and then reopen the module.
• We have enhanced both the layout and the user options for the Excel Calibration Report.

Bug Fixes

• Several problems were fixed with the Detailed Report that arose as a result of adding 0% to the Pre and Post-Calibration Grayscale modules. The report will no longer return a Fatal Exception when 0% is not read. Also, several formatting issues were resolved.
• We fixed some level errors with the DVDO Duo and AccuPel signal generator when using the 75% of Rec. 709 Gamut in the Color Management module.
• After using the AccuPel signal generator with the Advanced Color Management module, white could be reset to a different color. This has been fixed.

Known Issues

• When taking continuous measurements in the Gamma module using the BT.1886 gamma transfer function, you may see the target line revert to the default 2.22 level at the stimulus level being measured. This will be fixed in a few days in a maintenance release.

Version 2.4 is now available for download

ChromaPure 2.4 Release Notes

New Features

• We have added a new Manual Adjustment Tool for the DVDO Duo. You can now make adjustments to grayscale, gamma, and color gamut using the Duo's CMS functions from within ChromaPure without having to use the remote control. This tool also allows users to import/export calibration profiles and reset settings to default.
• We also include a beta version of the same Manual Adjustment Tool for the Lumagen Radiance. Currently, color calibration only functions at 100% stimulus. We will release an updated, final version in a few weeks.
• We have added an illuminant D65 ColorChecker. This is a useful tool for determining how accurately your display renders natural colors.
• We have re-engineered standard Auto-Calibrate to use the same algorithms used in Advanced Auto-Calibrate. This approach is more accurate, reliable, and more easily maintained. For Lumagen 8-point color users, please use 100% stimulus only until we make some small changes related to the Manual Adjustment Tool mentioned above. 125-point users are unaffected.
• We have added a new comprehensive Excel-based report to support Advanced Auto-Calibrate. This report samples the same suite of 24-colors as employed in the Advanced Color Management module.
• We have substantially upgraded the Conversion Utility Module, adding a Measure button and a set of RGB sliders that allows a user to select any 8-bit color as an RGB triplet. That color will display on screen.
• Small windows are now supported by the AccuPel DVG-5000, Lumagen Radiance, and DVDO Duo signal generators. These may be useful when calibrating plasma displays.
• The precision with which the AccuPel DVG-5000 renders user colors has been increased substantially by calculating those colors in discreet code values rather than percentages. This added precision is available for both 8-bit and 10-bit color.
• The Pre and Post-Calibration modules now include support for black level. This allows users to display pre and post-calibration black level and contrast ratio data in both the Detailed report and the Excel report. Users can skip a 0% reading if preferred.
• When using the Display 3/Display 3 PRO colorimeter in Plasma mode the application now automatically averages low-light single readings. (Continuous readings already employ averaging so these measurements are not affected.) This substantially improves repeatability. However, it also means that single low-light readings (0%-20%) will be noticeably slower.

Bug Fixes

• Some of the colors when using the constant APL mode in the AccuPel were wrong. This has been fixed.
• The dE calculations in the Advanced Color Management module at levels of stimulus other than 100% were wrong. This has been fixed.
• The gamma calculation at 75% in the Pre/Post-Calibration Grayscale module had been calculated incorrectly. This is fixed.
• Auto-Calibrate was adjusting 5% and 10% grayscale levels correctly in the Lumagen, but it was not setting the Lumagen menus to correspond with this selection correctly. This has been fixed.

See the DVDO Duo Video Processor and DVDO Duo Auto-Calibrate Bundle pages for details.

See the AccuPel page for a free firmware update. This update adds support for user-defined grayscale and color window sizes and user-defined checkerboards. See the Support tab on the AccuPel page for details.

Version 2.3.2 is now available for download

ChromaPure 2.3.2 Release Notes

New Features

• Enhanced Support for DVDO Duo Video Processor. The Duo now supports window and field test patterns, 5% grayscale test patterns, and colors at multiple saturations and levels of intensity. You can now use the Duo with the Advanced Color Management module and the 75% of Rec. 709 Gamut in the Color Management module.
• The Plasma mode now incorporates a new burst read mode provided by X-Rite that improves repeatability at low light levels on plasma displays. Our tests show that single readings on plasmas have very good repeatability down to 20% stimulus. To get good repeatability below that you may need to use Measurement Smoothing (but not on auto-cal). Continuous readings are fine at any level.

Bug Fixes

• Some of the colors when using the constant APL mode in the AccuPel were wrong. This has been fixed.
• The dE calculations in the Advanced Color Management module at levels of stimulus other than 100% were wrong. This has been fixed.
• The gamma calculation at 75% in the Pre/Post-Calibration Grayscale module had been calculated incorrectly. This is fixed.
• Auto-Calibrate was adjusting 5% and 10% grayscale levels correctly in the Lumagen, but it was not setting the Lumagen menus to correspond with this selection correctly. This has been fixed.

The addition of the Level of Stimulus drop-down in the Advanced Color Management module changed the tab order and inadvertently broke the macro that allowed users to use the Measure All button. Please download a new macro, unzip, and then copy to the C:\Program Files (x86)\Display Calibrations LLC\ChromaPure folder, replacing the original version. Measure All will now function properly.

Version 2.3.1 is now available for download. Please read the Auto-Calibrate Usage Notes.

ChromaPure 2.3.1 Release Notes

New Features

100%, 75%, and 50% stimulus are now selectable in the Advanced Color Management module, as announced in 2.3.

Enhancements

The Auto-Calibrate module has been substantially redesigned, offering the following enhancements.

• Gamma is now selectable and applies to both grayscale and color. Users may select a fixed power law value from 2.2 through 2.6 or BT.1886, which calculates the power law values at each level of stimulus depending on the display's peak output and black level.
• Grayscale and Gamma auto-calibration have been consolidated and can no longer be run independently.
• Grayscale/Gamma auto-calibration now includes a 10% and 5% increment option for Lumagen users.
• The selectable reference gamut now applies to both to standard color gamut and 125-point calibration.
• dE is user-selectable independently for grayscale, color gamut, and advanced color gamut (125 point).
• Advanced auto-calibration begins by automatically resetting all color gamut values and turning off echo in the Radiance. The active configuration is also automatically saved upon completion.
• The Number of Passes option in the 125-point calibration has been removed. One pass is sufficient for good results.

Bug Fixes

• Wait times have been increased for pre and post-calibration measurements to resolve reporting problems.
• The wait time for reference white in the 125-point calibration has been increased to resolve problems with lowered luminance levels.
• Reference white in the 125-point calibration now generates the same regardless of how signal uintensity was setup in the signal generator.

You may download a firmware update for the DVG-5000 that adds two new features, user-defined levels for the surround in window test patterns (previously they were all black) and the ability to turn on a single color (RGBYCM) that is then applied to all of the gray test patterns. This effectively adds hundreds of new test patterns. Both features are accessible in the AccuPel menu. The user-defined window surround is now used in ChromaPure to create constant APL windows, which may be useful for plasma calibration.

See the Support tab on the AccuPel page for details.

Version 2.3 will be available for download shortly when a production version of the Lumagen firmware that supports the 125-color calibration becomes available.

ChromaPure 2.3 Release Notes

New Features

• Advanced Auto-Calibration. Using a Lumagen processor this new feature allows calibration of 124 colors* throughout the Rec. 709 color space. It is an optional enhancement to the standard auto-calibration add-on and sells for $229 for new users and $79 as an upgrade for existing auto-calibrate users or as an add-on to ChromaPure Professional (Standard auto-calibrate is included for free in ChromaPure Professional).
• Support for APL window test patterns. AccuPel users will be able to use constant APL window test patterns for plasma calibrations.
• Support for additional signal generators, including the Quantum Data 882, 801, and 701.
• Support for additional meters, including the i1Pro 2 and the Minolta CS-100A.

* The Lumagen can adjust 125 colors, but one of them is 16,16,16 (black), which advanced auto-calibrate does not attempt to adjust.

Enhancements

• Added the ability to select 100%, 75%, and 50% stimulus to the Advanced Color Management module. Previously, levels of saturation were at 100% stimulus only. This enhancement affects the AccuPel and Lumagen signal generators and the internal test patterns.
• Added the ability to select 8-bit or 10-bit YCbCr 4:2:2 test patterns from the AccuPel generator.

Bug Fixes

     Improved the precision of the test patterns generated by the Lumagen.

You may download a firmware update for the DVG-5000 that adds two new test patterns, a color clipping pattern and a new version of the precision pluge that uses eleven 2-step bars (6-26) in addition to the original pattern that uses eleven 1-step bars (11-21). We also now offer a standalone application from which you can access all of the AccuPel test patterns and custom colors. You can also use this application to input 10-bit custom video values. This allows for much more finely defined custom colors (64-940 vs. 16-235) and grayscale patterns than available with 8-bit video.

See the Support tab on the AccuPel page for details.

Version 2.2.13 is now available for download.

ChromaPure 2.2.13 Release Notes

Improvements

• Added a "Measure All" option to the Advanced Color Management module.
• Added 75% field and 100% window rs-232 support for AccuPel DVG-4000 generator.
• Added some minor enhancements to the built-in Detailed report.

Version 2.2.12 is now available for download.

• Added support for the Spyder4 colorimeter.

Improvements

• The CIE chart used throuought the application has improved resolution.
• The Detailed Calibration Report now includes a 10% stimulus grayscale value.

Bug Fixes

• When selecting 75% window test patterns for the Lumagen processor, the application displayed a 100% pattern for magenta. This has been fixed.
• The White Balance module displayed dE values that were slightly different from those displayed in the Pre/Post-Calibration Grayscale modules. This has been fixed.
• The checkerboard (ANSI) contrast tool could return an invalid contrast value of Infinity. This has been fixed.
• The 75% of Rec 709 option in the Color Management module was broken. This has been fixed.

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.

  • 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.

  • 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.

Bug Fixes

• There was a bug that resulted in unpredictable results and instability with the French character set. This has been fixed.
• There was a bug with the X-Rite Hubble in which it would read only ft-L. It now reports luminance in ft-L and cd/m2 correctly.
• Because of the placement of the OK and Cancel buttons on the Options window, they would not appear when using some some video cards. This has been fixed.

Upgrade Policy

• Current ChromaPure users who purchased on or after June 1, 2010 are entitled to a free upgrade to Version 2.0.
• All other users may upgrade from any earlier version to 2.0 for $59.95.
• Any existing ChromaPure 2.0 user who wishes to upgrade their license to the new Professional version may do so now for an additional $800.

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 ft-L 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.

Licensed users will be provided with download instructions.
