IS-Mini User Guide
LightSpace CMS can be integrated with the IS-Mini LUT Box for accurate Display Profiling, LUT based Calibration and Look Management.
The following instructions are for using LightSpace CMS with the IS-Mini LUT Box for profiling and calibration LUT generation.
Operation of the IS-mini with LightSpace CMS is exceptionally simple.
- Connect the IS-mini to the LightSpace PC via the supplied USB cable, and start LightSpace CMS.
- Navigate to File/Upload, and select the IS-mini from the 'Select the device type' drop-down window.
- If there is no LUT active with LightSpace the NULL Cube option will be ticked and greyed-out, but is operational.
(As no other LUT is available the ONLY option is the NULL Cube)
- To make sure no LUT is active with the IS-mini select 'Upload', with the NULL Cube box ticked.
- Using the 'Calibration Patches' option select the desired patch size to use.
- Close the 'Upload' menu.
The Upload menu is located under 'File/Upload'.
To use the IS-mini as a Patch Generator navigate to the desired profiling mode - Calibration Interface, or Display Characterisation.
When the patch window is activate (the LightSpace CMS internal floating patch window has been made active by clicking the small colour display box when using Quick Profiling or Manual Measure modes) the output of the IS-mini will mimic the colour displayed, using the patch size pre-set via the 'Upload' window.
Profiling can then be performed as normal, using the probe connected to LightSpace, and with the IS-mini displaying the required patches on the display being profiled.
After profiling a Calibration LUT can be generated as normal, and with the LUT held within LightSpace navigate back to the 'Upload' menu, and with the 'NULL Cube' tick box un-ticked, the present LUT displayed within LightSpace can be 'Uploaded' to the IS-mini.
In this way, many different LUTs can be held within LightSpace CMS and quickly and easily uploaded into the IS-mini LUT box as needed.
Note: any LUT uploaded into the IS-mini may require rescaling via the 'Edit/LUT Manipulation/VideScale' before uploading if the workflow in us is TV legal range - see the following info.
TV Legal Profiling Workflows
If the image signal path is TV Legal, when profiling you will need to use the 'Active LUT' function within LightSpace to re-scale the colour patches correctly using a 64-940 rescaling LUT, either made via the 'Edit/LUT Manipulation/Append/1023->64-940' function, or through use of the 'LUT Image' for external LUT manipulation, applied to a bypass LUT made via 'File/New'.
Also, depending on the settings used within the IS-mini, you may need to pre-process the LUT via the 'Edit/LUT Manipulation/VideScale' or using the above 'Edit/LUT Manipulation/Append/1023->64-940' function before the LUT is uploaded to the IS-mini.
Note: To gauge if a rescaling is needed use the 'Calibration Interface' menu, and use the 'Patch Colour' function to toggle the IS-mini patch output colour between the Black patch  and Grey . If there is NO visible or measurable difference between the two patches a rescaling will be required as the output signal is being clipped.
