Test charts are perfect for testing digital cameras, cell phones or other objective measurements, but there are certain aspects of testing a camera that requires a real scene. One of these aspects is the correct white balancing for different types of illuminants. Another is determining the visual loss of detail due to noise reduction or the amount of noise in an image.
You can, of course, do tests with real scenes for yourself, but how to make these tests comparable over time? Or between different work groups from different parts of the world?
We have developed the lightSTUDIO to make this type of visual analysis possible. It provides the standard types of illumination and is large enough to illuminate a whole tabletop scene. It also allows remote control and the dimming of the lights from a PC using a USB interface.
The lightSTUDIO always comes with the same interior objects (see picture to the right) to produce a more accurate worldwide test comparison between labs. Each object was carefully chosen based on our experience in camera testing and can provide you with useful information about your camera system.
The lightSTUDIO with its interior objects and the switchable light sources has developed into one of our top selling products for image quality analysis. It is well on the way to becoming the industry standard for a camera test scene.
The Standard lightHEAD, our first and continuously demanded lightHEAD option, offers six different light sources including, four different fluorescent light sources (D50, D65, F11, F12) and two halogen based light sources (halogen, halogen with blue filter). Each light source is dimmable between 1% and 100% intensity. Each light source can store an intensity. These options cover the main standard types of illumination.
Directly control the lightHEAD by using the panel on the device itself or by using a software solution.
LED V2 lightHEAD
Exchange the Standard lightHEAD for the LED lightHEAD, which is based on iQ-LED V2 technology. Similar to our other LED products, the lightSTUDIO-L uses ten individual iQ-LED V2 elements to replicate almost any light spectrum for your camera testing. These elements use 41 SMD high power LEDs separated into 20 color channels and can reach a maximum intensity of 2000 lux.
With the introduction of iQ-LED V2, it is now possible to control the functionality of the lights without the use of a PC. You can store up to 44 different illuminants and one sequence on the device (controllable via microswitches on the device itself).
The lightSTUDIO-L uses a mini-spectrometer that has a better spectral resolution, higher sensitivity and a spectral range of 350 – 870 nm.
