Page 4: Safety Instructions
The following general safety instructions must be observed when operating the lightSTUDIO: Caution, the lightHEAD is heavy - several people are required for assembly! Wear safety shoes when moving the lightSTUDIO! The control cabinet must not be opened. Failure to do so can result in an electric shock! -
Page 5: For The Image Engineering Iq-Led Devices
DO NOT look directly into the open sphere or light source when using high intensities or sequences with low response time. DO NOT open the device when connected to power supply and without any instructions from the the Image Engineering support team. Image Engineering Seite 5 von 32... -
Page 6: Introduction
All variants of lightSTUDIO are equipped with interior objects which represent a wide range of real- world situations. Amongst these is, for example, a ColorChecker for measuring the color reproduction and the white balance. -
Page 7: Additional Hardware
Since version 1.6.0, the creation of illuminants for the LED lightHEAD is no longer available in the lightSTUDO software and now must be performed in the iQ-LED software. The lightSTUDIO software shares the same directory for all files, depending on the LED lightHEAD, with the iQ-LED software. See chapter 4.3.3... -
Page 8: Timecode Display
The timecode display is used for tracing movement and illumination scenes over time. For example, the movement of the horizontal test chart in the Moving lightSTUDIO may be scrutinized for artifacts in captured images or videos. Another possible application might be the examination of changes in the adaption of the camera to rapid light changes with the LED lightHEAD. -

[4] or the external reset button connected to the jack plug “Reset” [7]. For use with the lightSTUDIO-M, plug the USB cable of the timecode display into the corresponding USB port of the electrical control cabinet of the lightSTUDIO. -
Page 10: Led Lighthead V2 (Lightstudio-L)
All values measured in the acceptance protocol were measured three minutes after switching on the lights. 4.2 LED lightHEAD V2 (lightSTUDIO-L) The lightHEAD with iQ-LED V2 technique adds more functionality and a more comprehensive illuminance range (25 - 2000 lux) to the previous lightHEAD version. See the datasheet for more technical information. -
Page 11: Software Documentation
5 SOFTWARE DOCUMENTATION 5.1 Introduction The lightSTUDIO is a Windows software designed to control the lightSTUDIO and its components (Moving target option, Standard or LED lightHEAD, HDR box, timecode display, and iQ-Trigger). Each part can be accessed and controlled separately. Moreover, sequence lists can be created for simultaneous processing, including test chart movements and illumination with the lightHEADs and HDR box. -
Page 12: Installation
The GUI display of a lightSTUDIO-LMH with LED lightHEAD, HDR box, moving test charts, iQ-trigger and timecode display. 5.2 Installation Please choose the proper installer (32 or 64-bit) for your Windows operating system and run it. During installation, some drivers and additional software are installed. For proper software function, allow all drivers and software to be installed. -
Page 13: Settings
5.3 Settings 5.3.1 Moving option settings (lightSTUDIO-M) In the Moving option settings dialog, specifications can be modified for some components of the Moving lightSTUDIO. The default translation velocity [1] defines the transportation speed of the moving test chart in a range between 0.01 and 3.0 m/s. -
Page 14: Usage Of Led Lighthead
All calibration and creation of illuminants for the lightSTUDIO software must be performed in the iQ- LED software. Always use the current version of the lightSTUDIO and the iQ-LED software. Read the iQ-LED software manual and familiarize yourself with the calibration procedure and the creation of illuminants. - Page 15 The initial illuminance measurement was performed at 25 cm distance from front side. Spectral calibration: Recommendations for calibration repetition: During the first 600 working hours of the lightSTUDIO, perform a spectral calibration every 50 operating hours. After the first 600 operating hours, a calibration of every 150 working hours is sufficient.

Page 16: Hardware Status Bar
5.4 Hardware status bar The status bar gives information about the connected hardware components. If a component is available in your lightSTUDIO configuration, it is highlighted in green. The release state of the safety clamp is also displayed. NOTE: If the safety clamp is pushed in, the internal control unit stops the power supply to the motors immediately. -
Page 17: Sequence Lists
If the loop button [2] is activated, the complete sequence list for this component of the lightSTUDIO is repeated infinitely until the user stops the sequence. There are three buttons when editing the list: a new row is added to the table with the button “+” [3]. -
Page 18: Modules For Moving Option
The three modules are displayed in the software for controlling these devices. The iQ- trigger is connected to the lightSTUDIO directly without the iQ-Trigger USB box, which is part of the lightSTUDIO-M. The iQ-Trigger may be used as a stand-alone device with a USB box. See the documentation of the iQ-Trigger for further details. -

Trigger in the released state. In the sequence list, time stamps for the release of the iQ-Trigger can be edited. At each time stamp, the iQ-Trigger is released for the time defined in the settings (chapter 5.3.1). Image Engineering Seite 19 von 32... -
Page 20: Modules For Illumination
5.5.3.1 Standard lightHEAD If a Standard lightHEAD head is delivered with your lightSTUDIO, the illumination module lets you switch the corresponding lamps on and off [1] and set the intensity [2]. Only one lamp type can be illuminated at one time; hence, switching one lamp type on turns all others off. There are six types of lamps: F11,... -

[4]. Click on one of the selected illuminants in the list to turn it on. The temperatures of the iQ-LED modules impact the temporal stability of the selected spectra. The optimal operating temperature is between 33 and 36 °C; thus, the lightHEAD needs generally be warmed Image Engineering Seite 21 von 32... -
Page 22: Hdr Box
The HDR box can generate illumination ratios for measurements of High Dynamic Range scenes. The new generation of built-in LG4 devices allows an illumination ratio of up to 1:65000 inside the lightSTUDIO box. LG2 devices (until January 2018) The HDR module in the software enables you to control both LG4 lamps of the HDR box. The upper lamp is switched on using button [1], and the intensity is controlled with a slider or input field [2]. -
Page 23: Timecode Display
Enter start and end times and the intensity from 0…100 % depending on the selected mode. 5.5.4 Timecode Display The module for the timecode display (chapter 3.2) offers two operating modes: timer and counter. Switch between the modes with the menu [1]. Image Engineering Seite 23 von 32... -
Page 24: Module Spectral Measurement
During sequence playback of LED illuminants, button [1] is disabled, and the current measured spectrum (green) and the target spectrum (red) are displayed. The illuminance value and the Correlated Color Temperature (CCT) are also measured and displayed. Image Engineering Seite 24 von 32... -

(LS-LM + LS-LMH) 6.2.3 Remove the USB-Cable lightSTUDIO-L: Unplug the USB cable from the extension cord. lightSTUDIO-LM: Unplug the USB cable from the switch box. Open the cable straps holding the cable in place. -
Page 29: Unscrew The Spectrometer
The spectrometer is held in place by a few hex head screws. Use the 2 mm hex key to unscrew the spectrometer. When it moves freely in the brackets, pull it out carefully and make sure not to damage the fiber. Image Engineering Seite 29 von 32... -
Page 30: Shipping
6.3 Shipping Package the spectrometer carefully and ensure the Fiber does not get damaged. Use cushioning material. For shipping details please contact Image Engineering. 6.4 Installing the freshly calibrated spectrometer To Install the spectrometer, follow the steps above in reverse order. When fixing the fiber in the holding block, the top of the cosine corrector should be even with the plate. -
