VeriLUM®
VeriLUM® is a tool for ensuring consistent video display performance. Its goal is to make it easy and efficient to judge when a video display system is continuing to function normally or is in need of adjustment or replacement. VeriLUM® can be used for acceptance testing of a video display, tracking consistent video display performance over time, or performing gamma correction in conformance with the DICOM® Part 14 Grayscale Standard Display Function (GSDF) or any user-defined luminance response model.
VeriLUM® software can be installed on as many workstations as desired; no additional licenses are required. The VeriLUM® pod can be taken from workstation to workstation to perform measurements.
The software can be downloaded from this site. VeriLUM® can be installed and configured without the photometer. However, the photometer is required to measure luminance or chromaticity and to perform calibration and conformance tracking.
Also available from the Downloads page is a VeriLUM® User Guide in PDF format.
VeriLUM® can be purchased directly through IMAGE Smiths, Inc. or through one of our distributors.
Workaround for Multi-Display Calibration in Win 7 Pro
Here is a workaround to permit multi-display calibration using VeriLUM with Win 7 Pro. It is based on the fact that VeriLUM works correctly on the primary display. Each display is treated in turn as the primary display and a calibration is performed. Then the system is setup as multi-display and the various calibration LUTs are applied to the appropriate displays.
Setup a single display system using Display 1 (i.e. Head 0). Delete VeriLUM.Pref from C:\VeriLUM. Run VeriLUM and configure. Run VeriLUM and do gamma correction measurements. Then do tracking measurements. Exit VeriLUM. Copy the file named GCT0.dat from C:\VeriLUM and save it to another folder (for example, C:\Temp).
Setup a single display system using Display 2 (i.e. Head 1). Delete VeriLUM.Pref from C:\VeriLUM. Run VeriLUM and configure. Run VeriLUM and do gamma correction measurements. Then do tracking measurements. Exit VeriLUM. Copy the file named GCT0.dat from C:\VeriLUM and save it to C:\Temp. Then rename this file to GCT1.dat.
Setup a two display system. Delete VeriLUM.Pref from C:\VeriLUM. Run VeriLUM and configure. When VeriLUM exits to complete initialization, copy GCT0.dat and GCT1.dat from C:\Temp to C:\VeriLUM. Run VeriLUM. Click on DISABLE GAMMA CORRECTION. Click on ENABLE GAMMA CORRECTION. Now both displays are calibrated.
We apologize for the necessity to use a workaround. If a future version of Windows 7 fixes this issue we will notify our users.
