Display Profiling
CalMAN now provides two display profiling algorithms, Intelligent Resolution Profiling (IRP) and
Lightning LUT, for profiling a display’s color rendering performance and creating a corrective 3D
LUT.
•
Intelligent Resolution Profiling™ (IRP)
The new Intelligent Resolution Profiling algorithm is CalMAN’s highest quality method of creating
3D LUT display correction data. If you have from one to four hours available to run a 2000 to 3000
point display profile, the IR Profile process is your best choice for producing accurate 3D LUT
correction data.
Every display has some nonlinearity, and IRP is the best 3D LUT process available for correcting
nonlinearity. The IRP algorithm, which incorporates proven Dynamic Linearity Correction (DLC)
technology, produces more accurate results, with a more efficient process, with a user-friendly
process.
The IRP algorithm uses DLC to analyze the display linearity with a small profile of color sample
points, then runs a heuristic analysis to evaluate the degree of linearity error that can be corrected
within the selected time or with the selected number of measurement points. The IRP algorithm
then measures predetermined and DLC-determined color points, develops correction data to the
selected calibration standard, and interpolates the correction data out to the desired number of
final 3D LUT points. The final display calibration LUT has the highest accuracy possible within the
selected time or point limit, for incredible accuracy with any RGB or video display.
IRP provides maximum correction for gamma, grayscale balance, RGB crosstalk, and color gamut,
plus it corrects luminance and saturation nonlinearities to the maximum extent possible within the
selected time or point limit.
o
IR Profile (time based)
The “IR Profile (time based)” Calibration Type is the default display profiling process, which is your
best and most user-friendly choice to calibrate most displays.
1.
On the AutoCal Setup dialog, under Calibration Type, select “IR Profile (time based)” (figure
2).
2.
Then, use the Profile Time slider, to select how much display quality you have time for,
anywhere from 30 minutes to maximum display quality (6,000 points max).
3.
Click the OK button to begin the Intelligent Resolution Profiling process.
