Title: Johan Pontus Ebelin: Inventor in Color-Vision Accessibility

Introduction

Johan Pontus Ebelin is an inventor associated with Nvidia Corporation and based in Skåne, Sweden. His work includes an image-recoloring technique designed to make visual information more accessible to people with color vision deficiency (CVD).

Latest Patents

Ebelin is associated with 1 patent, titled “Luminance-Preserving and Temporally Stable Daltonization.” The invention addresses the difficulty people with CVD may have distinguishing certain colors, such as red and green. Daltonization modifies image colors to help convey information that might otherwise be difficult to perceive.

The technique aims to preserve luminance, helping maintain the image’s appearance for viewers with normal color vision and viewers with CVD. Unlike approaches that rely on each image’s content and may map the same color differently across video frames, this method operates on pixels to provide consistent color mapping. That consistency is intended to reduce temporal artifacts such as flickering.

Career Highlights

Ebelin’s listed patent connects his work at Nvidia Corporation with research into image processing and accessibility. The invention focuses on making color-coded visual information easier to interpret while maintaining stable appearance across sequences of images.

Collaborations

Ebelin’s listed coworkers include Cyril Crassin and Tomas Guy Akenine-Möller. Their shared professional context is associated with Nvidia Corporation.

Conclusion

Johan Pontus Ebelin’s patent presents a luminance-preserving approach to daltonization that seeks to improve accessibility for people with color vision deficiency while maintaining temporal consistency in moving images.
