Pelican Imaging publishes its oncoming paper at SIGGRAPH Asia 2013, including many high resolution images straight out of their reference system:
PiCam: An Ultra-Thin High Performance Monolithic Camera Array
Kartik Venkataraman, Dan Lelescu, Jacques Duparré, Andrew McMahon, Gabriel Molina, Priyam Chatterjee, Robert Mullis, and Shree Nayar
The full resolution pictures on Pelican's site are 3264 x 2448 and over 30MB in size, too large to post here. A down-scaled version of 1000 x 750 and full resolution crop of one of the images are below:
There are many more original images on the Pelican site, including ones taken at 30-50lux/15fps and 5-10lux/7fps ones. It's quite rare that an image sensor manufacturer posts the official full-resolution samples, including ones shot in the difficult lighting conditions.
An official press release is expected tomorrow. Thanks to LG for giving me a heads-up!
Update: The official PR is published on PRNewswire now.
