There have been several commercial manufacturers of lightfield cameras (Lytro being another one). Which part is patented?
The hardware tech is different too, Raytrix seems to be using a microlens setup (like most other lightfield cameras). A microlens setup also reduces resolution fwiw.
- fxtentacle 5y agoI was referring to US 8,619,177 B2. This one also uses a multi-lens arrangement which reduces resolution. If I remember correctly, Lytro went bankrupt in the period between when Raytrix filed their patent and were granted it, so they "got lucky".
- Scene_Cast2 5y agoI'm surprised that there's a patent like that - university researchers have been making custom microlens lightfield setups for some time. If I understand the K|Lens implementation correctly, they stuck a mirror-based kaleidoscope in the middle of the lens. I don't know if there's anything extra on top of that.
- fxtentacle 5y agoAgree. BTW it looks like the KLens patent was applied for in 2012 so while the Raytrix patent was still in evaluation. And both are German companies. There must have been a wave in popularity in researching this kind of technology. That said, I wonder what KLens has been doing from 2014 (when their patent EP 2 533 199 B1 was issued) until now.
