The first local dynamic HDR optimizer

What it does

Lumagic is a sophisticated and patented algorithm using an HDR input optimizing luma and chroma to the perception of the human eye. It works real time and can be used for live production.

Conventional static mapping vs Lumagic

The above pictures show the difference between static and local dynamic conversion of a high dynamic scene. Lumagic provides more than simply better image quality, it also affects the way in which content is produced. By optimizing the lighting balance and exposure, aperture setting become less crucial. As long as the information in the captured scene is not absolutely crushed or burnt-out, Lumagic will map it into the optimal contrast for the human eye.

Use cases

Sports in sun and shade

In outdoor sports such as soccer sudden changes from sun to shade can be a challenge: even if the camera team reacts quickly, the ball invariably will be briefly underexposed, colors will change. Not with Lumagic: luma and chroma will be auto-corrected in real time. And your viewers will love it.

Reporting in the field

A common situation in the field: the background in the sun is bright-lit and overexposed while the reporter in the foreground appears too dark. Add a fully equipped production lighting team: the footage improves somewhat but the reporter suffers. The glaring light makes him squint and adds to the heat. A few minutes into the shot, new make-up is required. With Lumagic you can leave the lighting team and all that equipment at home. Fully automatically overexposed and underexposed sections are corrected. A perfect shot, faster and cheaper.

Efficient studio production

Looking for savings in a studio production environment? Maybe you can save some of those camera men. With Lumagic, there is no need to have a camera man in place just to adapt the exposure. Lumagic does it for you, automatically

Benefits

Improve your native HDR

Use Lumagic to optimize your HDR before broadcasting it. Automatically, the footage will become more convincing, colours brighter, contrasts improved. The HDR is adapted to what the human eye can see.

Use your HDR to create brilliant SDR footage

Still, only few consumers own one of those expensive HDR screens. But here comes the maybe biggest advantage of Lumagic: you can use the HDR to create amazingly brilliant SDR content. Let your SDR consumers participate in the HDR experience.

Archive in SDR and reconstruct the HDR

Few broadcasters like to add another house format. But switching to HDR doesn’t necessarily mean switching to a HDR house format. You can “compress” nearly loss-less your HDR and archive this material. Lumagic’s patented algorithm is able to maintain almost the entire contrast range of the original HDR image when down-converting to SDR. When upconverting the SDR signal again, this becomes key for reconstructing the HDR image almost to its original contrast range.

Reduce the need for aperture changes

Today, even with an agile camera man correct aperture changes can be a challenge, especially in sports, music, and other environments with fast changing light conditions. Lumagic, however, can react not only much faster (within a couple of frames) but also manage the luma on a sectional level. Hence, the camera man can focus on catching the right content and get those breath-taking shots.

How does it work in detail?

The patented algorithm is based on models of the human visual system taking into account the preference of contrast and chroma perception. 144 segments of the video are dynamically processed frame by frame, darker areas brightened, while at the same time retrieving more detail in overexposed sections. With only 40ms delay in HD and 60ms in UDH, contrast compression, luma and chroma corrections are calculated. Different color spaces are not simply clipped during transformation but rather intelligently mapped generating a balanced video impression most appealing to the human eye.
