Fixing distortion and tilt is a tricky problem. It was solved back in the large format days by having lens boards and film backs that could tilt, shift and move around in all kinds of directions. And while tilt-shift lenses are available for modern cameras, the one thing they can’t fix is lens distortion – particularly from things like fisheye lenses. Of course, such distortion can be fixed in software using manual tweaks or custom lens profiles. But figuring it out automatically?
For software to figure out how to correct such distortion usually takes multiple images so the software can “learn” the characteristics of a lens. But according to Nikkei, Panasonic has developed a new technology that seems to be able to do it from just a single image. Right now, it’s still in the testing stages while they determine if the method can be practically implemented.
