The participants of the NovaStar training course were eager to learn and had a lot of fun
As part of the AVMS NovaStar training offered, we have succeeded in providing unique training for technicians and users from Germany and abroad.
There are numerous tutorials on various NovaStar products on the manufacturer’s website.
During a NovaStar training course, you will learn about all aspects of the NovaStar Control System, can ask questions spontaneously and exchange ideas with other course participants.
The training is held in German.
Well-trained employees ensure quick set-up and also implement spontaneous changes.
The training covered all the important topics relating to the current Novastar LED controllers and provided an outlook on new products.
The calibration and adjustment of LED modules are crucial steps to ensure precise color rendering, uniform brightness and optimum contrast.
This is particularly important in professional applications such as studios, events and digital signage.
Calibrating LED devices is a complex process that requires expertise and specialized measuring equipment.
NovaStar offers a range of tools and functions to enable precise control and calibration of LED panels.
HDR applications open up new possibilities for impressive picture quality, but also place higher demands on calibration.
The professional use of LED displays in conjunction with cameras is crucial for professional results.
Only a perfectly maintained and calibrated LED wall cuts a fine figure at trade fairs and events.
Regular training is a necessary prerequisite for this.
AVMS NovaStar training: Calibration and adjustment, HDR applications and camera alignment
Why is calibration so important?
- Color accuracy: Ensuring that colors are displayed on the LED screen as intended.
- Brightness leveling: Ensures even brightness distribution over the entire surface of the screen.
- Contrast optimization: Maximization of the contrast range for better image quality.
- Compensation of ageing effects: Compensation for changes in the luminosity of the LEDs over time.
Calibration procedure:
- Measurement: A spectroradiometer is used to measure the color values, brightness and contrast of the screen at various points.
- Comparison: The measured values are compared with the target values defined in a color profile or a look-up table (LUT).
- Adjustment: The settings of the LED controller or the image processing system are adjusted so that the measured values correspond to the target values.
NovaStar – A leading provider of LED control solutions
NovaStar is a well-known manufacturer of LED control solutions, offering a wide range of products for various applications.
NovaStar’s software offers extensive calibration functions to enable precise control of LED panels.
Important NovaStar functions for calibration:
- Color management: Creation and management of color profiles.
- Brightness adjustment: Individual brightness adjustment for each LED pixel.
- Gamma correction: Adjustment of the brightness curve for a true-to-life display of images.
- White balance: Correction of color casts to achieve a neutral white.
HDR applications of LED devices
High Dynamic Range (HDR) makes it possible to display images with a significantly greater contrast range and a wider color palette than with Standard Dynamic Range (SDR).
HDR-capable LED devices can therefore produce more realistic and impressive images.
Challenges with HDR applications:
- Calibration: The calibration of HDR displays is more complex than with SDR displays, as a larger color space and a higher dynamic range must be covered.
- Content creation: The creation of HDR content requires special tools and know-how.
Professional use in conjunction with cameras
The right combination of LED displays and cameras is crucial for optimum image quality in broadcast and production environments.
Important aspects:
- Color space: LED displays and cameras should support the same color space to ensure accurate color reproduction.
- Gamma: The gamma curve of LED displays and cameras should be coordinated in order to achieve a natural display of brightness transitions.
- White balance: The white balance of LED displays and cameras should match to avoid color casts.
