Patented technology to create HDR images from video sequences

While the traditional way of creating HDR photos has always been bracketing, its recurring drawbacks when it comes to moving subjects led us to investigate new HDR imaging methods. Inspired by astro-photography techniques, we’ve developed a unique image processing technique to create HDR images from video sequences.

In the field of astrophotography, a number of methods have been developed to recover details in the shadows. By using calculation-heavy algorithms and stacking multiple exposures, it is possible to increase the signal to noise ratio, allowing to recover details in dark areas without losing in picture quality. Combining this set of techniques to HDR photography principles, our technology uses multiple video frames to create pictures with maximum detail in the highlights and shadows.

We get our first exposure directly from the video, without any processing. For that, it is best to expose for the highlights when shooting the scene.

We get our second exposure by stacking and morphing a number of neighboring frames.

We get our final exposure by stacking a high number of frames, revealing as much detail as possible in the shadows.

We then merge our different exposures into a single HDR picture.

The last step is the tone-mapping process, converting the HDR image into a displayable picture.

Our innovative technology is opening new doors in terms of shooting possibilities, removing the constraints of movement in HDR photography.
While this new method for creating HDR images goes hand in hand with aerial photography (constant movement, high-contrast scenes and loads of video frames to use), it is also a valuable tool for photographers and videographers looking to extend their shooting possibilities. HDRinstant can be used to get high-detailed pictures in low light situations, turn video highlights into stunning pictures, convert series of images taken in burst mode into HDR pictures, recover old video footage and even create HDR videos from standard video files.
