Lytro Image Manipulation: Linux Tools to insert Images into LightField Pictures

Lytro Image Manipulation: Linux Tools to insert Images into LightField Pictures (picture: ebina1)A few days ago, we reported about ebina1′s tool “Refocus”, which makes the processing of Lytro RAW images possible in Linux.
Now, ebina1 has taken his work further, and released two more programmes that, for the first time, give users the ability to do (one kind of) image editing with Lytro LightField pictures:

insert_focus lets you insert an image at a specified focus level within the picture. Continue reading

Lytro Roadmap: Director of Photography hints at Consumer and Professional Cameras

Eric Cheng talks about Lytro and Living Pictures, Photokina 2012 (photo: LightField Forum) Lytro’s first generation LightField camera recently celebrated its first birthday. So what, you might ask, is next up Lytro’s sleeve? What will the second generation camera be like, and what lessons from the first generation will be turned into improvements for the second one?

In a Techhive article that focuses (pun intended) on an alternative way of creating interactive click to focus images, we found what may be the first official hint at Lytro’s upcoming products. First off, there aren’t many details – let alone a timeframe – but we’re still a bit excited.

Lytro’s Director of Photography Eric Cheng had this to say during a discussion of some restrictive aspects of their Terms of Service:

Mems|Cam: Software Refocus for Smartphones without LightField Technology

Mems|Cam: Software Refocus for Smartphones without LightField Technology (photo: DigitalOptics) Ever since their first appearance in the News, Lytro’s most prominent LightField feature was software refocus. The ability to take a picture, and set and change focus after the fact has inspired many of us.
While Toshiba is working hard on commercializing that same LightField technology for use in smartphones, California-based company DigitalOptics is taking a shortcut with similar results:
Instead of taking a single photo through a microlens array, DigitalOptics’ Mems|Cam takes a series of pictures at different focus distances. After stitching the photo sequence together, the resulting pictures can be refocused just like Lytro’s LightField pictures. Continue reading

Refocus: Linux Tool to Process Raw Lytro Images

Refocus: Linux Tool to Process Raw Lytro Images In our Forums, there’s now something for Linux users: User ebina1 has shared a small Linux tool that allows the processing and refocusing of Lytro RAW images (which can be extracted via lfpsplitter).

I wrote a short program to process the raw data the lfpsplitter extracts from the .lfp file (not the -stk.lfp).
It lets you generate individual images focused at different depths. The pictures aren’t quite as good as what you get out of the Mac software, but still fun if you want to play with refocusing images.

Small Linux program to refocus extracted Lytro RAW image files.

The company even showed off a test unit and exciting features at its research lab in Kawasaki, Japan.

IDG News Service reports that the current version of the module, which is scheduled for production “at the end of this year or shortly after”, is a little cube that measures just 8 mm on its sides. Toshiba uses a traditional 8 Megapixel CMOS sensor to create still images with 2 Megapixels effective resolution, as well as LightField video at 30 frames per second (no word specifically about video resolution, though). A future version will use a 13 MP sensor and produce 5 to 6 MP LightField images.
