175 years ago, British inventor William Henry Fox Talbot recorded the first ever photograph on paper. To celebrate the subsequent evolution of cameras and photography, Lytro treats us to an infographic overviewing the major development steps of almost two centuries.
The infographic includes paper photography and digital photography, and ends with the most recent advances in digital imaging, e.g. the Gigapixel camera and their own Illum light field camera: Continue reading
Up until now, Lytro users looking for the iOS app that would let them connect to their Illum wirelessly could only find a notice promising that the “Lytro Mobile for Illum” would be “coming soon”.
A new Lytro support document now states the exact release date of Lytro Mobile 2: it’s tomorrow, August 19 2014.
Update on 2014-08-19: You can now get the app here:
Lytro Mobile 2.0 is the first major release of an app compatible with both the first-generation Lytro camera and the Lytro Illum. The app allwos viewing and interacting with Living Pictures directly on your iPhone or iPad, including software refocus (single tap), synthetic aperture (two finger twist) and perspective shift (rotate device; 64-bit devices only).

Ricoh researchers Sapna A. Shroff and Kathrin Berkner have lodged a patent application that describes a new way to dynamically adjust the recording parameters of a light field camera. The US Patent and Trademark Office has recently published patent application US20140192255, entitled “Dynamic Adjustment of Multimode Lightfield Imaging System Using Exposure Condition and Filter Position”, in which the authors use a non-homogeneous filter module at the pupil plane of a multimode imaging system, which can be moved and thus used to modify the imaging system’s exposure conditions.

Lytro’s confidentiality request for the FCC‘s pictures of the Lytro Illum expired yesterday, so the FCC have just published their detailed internal and external photographs of the light field camera and further test setup photos of the preliminary Illum version which was submitted for testing on April 23 2014. (Lytro later re-submitted the shipping Illum version for FCC approval.)
Also newly released is the preliminary user manual for the Illum (link at the end of the article) that was submitted to the FCC, which contained a few asterisks for features that were “not available on the test unit”, namely the Lytro button, AF and AEL buttons, and Continuous Shooting Mode.
Just a few years ago, mobile displays took a leap forward with increased pixel densities that ensure crisp images on realtively small screens. Today, most smartphones feature displays with up to 538 pixels per inch (ppi) – a resolution that is much higher than what the human eye can see. So what’s the next display innovation we can look forward to?
In her recent article on IEEE Spectrum, Sarah Lewin introduced two companies that are working on making what she calls “holographic” light field displays (i.e. glasses-free 3D displays) a reality.
Ostendo Technologies recently presented the results of nine years’ work at the Display Week conference: An array of 4×2 Quantum Photonic Imager chips (each consisting of LEDs, image processors and embedded rendering software) plus microlens array form a 1 megapixel (1024x768px, XGA resolution) prototype display which sends out light not into every direction – like conventional displays do – but rather into very narrow, collimated angles of light. This enables the prototype to emit different images into different directions, producing about 2,500 different perspective views, so the image and motion displayed appear consistent regardless of the viewer’s position.
