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.

IS-Mini Overview

LightSpace CMS will work with both the original IS-mini, and the new IS-miniX.

Initial Setup
IS-mini LUT Box

Operation of the IS-mini with LightSpace CMS is exceptionally simple.

  • First, power on the IS-Mini and make sure a valid input signal is connected.
  • 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.
IS-mini Upload

The Upload menu is located under 'File/Upload'.

Null Cube

When the 'Null Cube' tick box is used, all IS-mini settings are nullified, not just the 3D LUT. Should it be desired that IS-mini settings other than the 3D LUT remain as set, upload a real Null/Bypass 3D LUT (generated via File/New), as that will only 'null' the 3D LUT.

Although the option is labeled 'Null Cube', an actual Cube (LUT) is not necessarily loaded into the LUT box, depending on the box's capabilities/options. A 'reset' command may be issued, rather than an actual Cube file uploaded.

Profiling Operation

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.

LUT Upload

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 may need to use the 'Patch Scale' function within the 'Options' menu to re-scale the colour patches correctly.

Also, depending on the settings used within the IS-mini, you may need to pre-process the final calibration 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 patch rescaling via the 'Patch Scale' function 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 [000] and Grey [013]. If there is NO visible or measurable difference between the two patches a rescaling will be required as the output signal is being clipped.
