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 →
One of the most exciting fields in science where light field imaging (or plenoptic imaging) has a great potential is microscopy: Not only is the depth of field very limited in microscopy, it also enables us to observe things much smaller than what the eye can see. Extended depth of field and 3D reconstruction would offer many opportunities, such as to better understand the three-dimensional internal structure of plant- or animal cells and tissues, to name just one example.
3D imaging using multi-camera approaches is very difficult in microscopy due to space limitations and the strong effects of parallax, but light field imaging can solve these problems. Until now, however, light field microscopy is still largely defined by resource-intensive post-processing, which limits real-time applications and observations.
In a recent publication in the journal Optics Express, researchers from Seoul National University and Harvard Medical School in Boston present a novel light field microscopy system that enables light field microscopy with real-time 3D display. Continue reading →
In the following two videos, Lytro founder Ren Ng gives us a first hands-on look at the company’s new flagship camera, the Lytro Illum.
He also shows off the features of the new iPad app that will be released together with the Illum in July 2014, and offer “tap to refocus”, Perspective Shift, and even adjust the depth of field, in Living Pictures.
With their newest Youtube-Upload, German LightField specialist Raytrix demos the LightField features of their R29 camera.
The HD video includes original footage recorded with the high-end camera (resized from 3288 x 2192 = 7.2 megapixels; and 100 % crops), and demonstrates the reconstruction of 3D information – even at a subject-to-lens distance of 400 meters – as well as software refocus and extended depth of field.
Video frame rate for full-resolution imaging is 5 frames per second.
