Light Publishes L16 Full Resolution Images
Two weeks after Light L16 computational camera shipments start, there is still no single user review anywhere on the web. However, LightRumors notices that Light Co. has released few full resolution images on its web site. The images are processed using Light’s proprietary software, Lumen, which is powered by Light's proprietary Polar Fusion engine. The engine computationally fuse the many images captured by the L16 to create one high-quality image.

So they still rely on manual adjusting of the depth map in their software due to artifacts.
ReplyDeleteThe setting of the depth of field happens in the desktop software yes. I don't believe you do any adjusting to the depth map itself. And I don't know what you mean by artifacts. If there are problems with the blending of the images and the depth of field, the software will let you repair it.
DeleteIt's in the tutorial.

It's specificially mentioned that some manual correction is needed, and the examples of DoF artifacts are given. As I understand it, L16 simulates DoF from a depth map estimated from multiple sensors, this isn't entirely accurate just like any stereo depth estimation, so it needs manual tweaking.
That article does NOT say that some manual correction is needed on EVERY photo... here's what it specifically says:
Delete"Occasionally, these depth maps contain inconsistencies, especially when there are similar colors or patterns that overlap. In these cases, Lumen’s algorithms have difficulty determining what should be in focus and what should be blurred."
You're not fixing the depth map, you're repairing the image based on the depth map
There are some very nasty artifacts around the prow of the ship.
ReplyDeleteDon't know whether those are caused by the camera or by jpeg compression
DeleteThe grass in the shipwreck image has patches of sharpness and dullness. Due to bad depth map causing misapplication of bokeh perhaps?
ReplyDeleteThe foliage in the canyon image has no texture. Some regions (example: image right) have transition from dull to sharper for no apparent reason.
For the price some of the artifacts are atrocious... now if the device was 1/2 size and 1/2 the price it would be a great toy...
ReplyDeleteIndeed, a toy! And nothing more...
