Dynamic Profiling™
|
CalMAN’s Dynamic Profiling system includes a new display profiling and 3D LUT targeting engine. There are two LUT creation methods provided with this profiling and targeting engine, Intelligent Resolution Profiling™ and Lightning LUT.
CalMAN’s Intelligent Resolution Profiling creates an extremely accurate profile for very nonlinear displays in just two to three hours, compared to six to ten hours with previous static profiling methods. And, for displays with moderate linearity, CalMAN’s Lightning LUT process creates an accurate profile and 3D LUT with just 100 reads; about five minutes. Read more… |

Intelligent Resolution Profiling™ (IRP)
|
IRP creates optimized 3D calibration LUTs for less linear displays in as little as 30 minutes, by combining static display profile measurements with Dynamic Linearity Correction to specifically target nonlinear areas of a display’s color space with optimized measurement coverage. Optional selection of measurement time or measurement point limits provides the most accurate display correction possible within the selected limits. Read more…

Dynamic Linearity Correction™ (DLC)
|
CalMAN® uses a dynamic discovery algorithm to optimize its coverage of a display’s gamut volume. This feature detects the linearity of a display and prioritizes nonlinear areas, allowing for a redistribution of the measurement points to create a more detailed map of the display’s color gamut. Dynamic linearity correction produces greater overall display accuracy for a given number of profiled color points. Read more…

Drift Compensation
|
CalMAN®’s IRP takes additional measurements to track the drift of display over the time it is under test. This allows the measurement data to be corrected for both luminance and chromaticity to produce a final 3D LUT with a higher level of accuracy. This is especially valuable on displays that exhibit image retention. Read more…

Natural Neighbor Interpolation
|
CalMAN® creates 3D calibration LUTs from display profile data using natural neighbor interpolation, with an innovative implementation of Delaunay triangulation and Voronoi cell weighting concepts, for smoother and more accurate mapping than is possible with traditional trilinear or tetrahedral interpolation. Read more…

Shadow Consistency
|
CalMAN®'s 3D LUT interpolation algorithm analyzes a display’s shadow performance and adapts its targeting from absolute color accuracy to ultimate color consistency. With this, a display’s lowest luminance levels smoothly transition to black, when accurate color is unattainable. This shadow consistency feature of CalMAN’s 3D LUT algorithm assures the most accurate color possible on any display without shadow color artifacts. Read more…

Lightning LUT
|
Lightning LUT creates optimized 3D calibration LUTs for displays with at least moderate linearity, in less than five minutes. Lightning LUT uses an innovative conversion matrix algorithm to correct gamma, grayscale balance, RGB crosstalk, moderate color saturation and luminance nonlinearities, and reduce wide gamut volume to a target volume.

Hybrid Targeting for AutoCal
|
To provide the highest level of luminance accuracy when creating a 1D LUT for grayscale or color critical imaging systems, CalMAN employs a hybrid JND/dE2000 AutoCal targeting algorithm.
By combining the individual strengths of the JND and CIE dE2000 metrics, CalMAN provides unparalleled luminance accuracy, along with exceptional chromaticity accuracy, for both grayscale and color imaging systems. Read more… |

Color Comparator™
|
Direct visual color comparison has long been accepted as a valid and valuable method for evaluating the color rendering accuracy of video displays. CalMAN Color Comparator charts provide a direct visual comparison between desired target colors and a display’s actual measured colors, hearkening back to the intuitive analysis of the first optical comparators. These visual color comparisons let you actually see a display’s color errors, to intuitively decide which color differences are acceptable and which are excessive. Read more…

Color Matching Functions
|
Recent advances in display technology have exposed serious display incompatibility with the 1931 CIE color matching function (CMF) that has long been depended upon to derive a numerical description of color (e.g., X,Y,Z) from spectral measurement data. CalMAN now provides access to several alternative CMFs that have been proposed by academic researchers to derive a more accurate numerical description of the color energy created by all display devices.

Constant APL Test Patterns
|
CalMAN Constant APL test patterns stabilize any auto dimming, ABL, or auto iris action that can’t be disabled during display calibration. The Constant APL patterns are also constant chromatic, maintaining accurate gamma measurements not only for grayscale levels, but for all colors, to enable the most accurate gamma measurements and adjustments possible, on any display type.

MobileForge
|
The free MobileForge app for iOS, Android™, and Fire TV devices allows manufacturers, reviewers, and users test a mobile device’s conformance to industry color standards with the MobileForge app and free CalMAN ColorChecker software.
MobileForge also allows users of CalMAN® home theater calibration software to automatically generate test patterns for DIY home theater calibrations directly from their mobile devices. Read more… |

Eyeglass
|
CalMAN® Eyeglass is a free 3D LUT visualization tool for comparing before-and-after effects of a corrective 3D LUT on a laptop screen or monitor. Load your own still image files into CalMAN Eyeglass to see the before-and-after effects of your 3D LUT calibrations. CalMAN Eyeglass can be used with any of SpectraCal's 3D LUT software, including the free CalMAN ColorMatch software. Read more…
