The quality of a DSLR in a camera that fits in your pocket – that’s what camera startup Light promises with the just announced L16, the world’s first multi-aperture computational compact camera, which is made up of 16 individual camera modules.
Are you excited about the imminent release of Lytro’s second-generation light field camera, the Lytro Illum? Here’s something to pass some of that time:
Jackie Dove from TheNextWeb sat down with Lytro CEO Jason Rosenthal recently, to talk about the Illum and it’s significance for the future of photography. “Interchangeable lenses”, “DSLRs“, “Photoshop and Lightroom” and “Android” are some of the most important keywords that came up during the interview.
As much potential as light field technology has, Lytro is – until now – the only company actually going that way with consumer cameras.
Now, according to Canon Rumors, Canon may be one of the first “big” camera makers working on integrating light field features into DSLR and Point-and-Shoot cameras:
We’re told that Canon is working to implement depth of field control in upcoming PowerShot and Rebel DSLRs. Continue reading
In comparison to conventional digital cameras, current light field cameras are still limited in spatial resolution and depth of field control. Using a new camera combination, Vivek Boominathan and colleagues from Rice University were able to lift these limitations.
In a recent publication, the authors present a prototype hybrid imaging system consisting of a Lytro light field camera (380 x 380 pixel spatial resolution) and a conventional Canon DSLR (18 megapixel resolution). The setup doesn’t require co-location or prior calibration of the two cameras. In conjunction with a “simple patch-based algorithm”, the researchers were able to produce a high-resolution light field with 9 times the Lytro camera’s resolution and about 1/9th of the camera’s depth of field.

Today’s light field processing algorithms have mostly been tailored for relatively low image resolutions in the range of a few megapixels. That means, even with increasing sensor resolutions, light field technology will still be effectively limited by resolution. The analysis of light fields at high spatio-angular resolution, so-called “gigaray light fields“, remains a technological challenge due to the sheer computing power it requires.
Researchers at Disney Research in Zürich, Switzerland, have come up with a new, faster way of processing such light fields. Their secret: ignore some of today’s established practices in image-based reconstruction, and try something different.
