Two quick notes regarding software updates for mobile apps:
Nokia’s Refocus App for Windows Phone 8 has just been released for all Lumia Smartphones, including those that don’t feature PureView cameras. The current app version 18.104.22.168 also promises better focus.
Lumia users can get the app for free in the Apps+Games Store.
Lytro has released a small update to their Lytro Mobile App (version 1.2.2), which brings “bug fixes and performance improvements”, especially “fixed support for HTTP 1.1 Content-Length: chunked”. Lytro Mobile is available for free in the iOS App Store:
Nokia’s Refocus app was released to a number of PureView Lumia devices about a month ago. In contrast to the light field technology employed in the Lytro light field camera, Nokia’s solution is purely software-based and uses an ordinary digital camera module and several exposures to create a refocus effect.
So how do the two systems and their resulting pictures compare visually?
CNET Australia tries to answer this question in their “refocusing challenge“, showing us refocus-pictures of the same scene, taken with both a Lytro camera and a Nokia Lumia 1520.
Here we take a look at the author’s conclusions, and add our own observations from the picture comparison: Continue reading
Back in October, Nokia first presented their Windows Phone app “Nokia Refocus”, which offers a Lytro-like post-capture software refocus feature for Nokia’s conventional camera modules. The company promised to make the app available not just to owners of the brand-new Lumia 1520 phablet, but to all of their PureView enabled Lumia smartphones.
Just a few days ago, the app was finally released for the broader audience. Nokia Refocus is now available for the Lumia 920, Lumia 925, Lumia 928, Lumia 1020, and other PureView enabled smartphones that are running the Amber update.
With the introduction of interactive refocus to the (camera enthusiast) mainstream, Lytro opened a new, compelling way to tell stories with images. The software refocus feature is fundamentally embedded in light field technology, but it can be recreated with a bit more user effort, using an ordinary camera. We’ve seen methods using a video with moving focus as well as camera apps that use multiple exposures at different focal lengths, such as Refocus (Windows Phone) tap2focus (iOS) or FocusTwist (iOS). Advances in the (conventional) camera world, such as the super-fast MEMS technology, are adding to the “refocus hype” – both by making the creation process faster and easier, and by promoting refocus as one of the new products.
Nokia, one of the major investors around Pelican Imaging and their Array Camera, has just announced a new smartphone app for their Lumia series that uses the “multiple exposure” refocus workaround: Continue reading
Following headlines about Nokia’s 20 Million Dollar investment in Pelican Imaging, and more recently, confirmation of plans to include light field technology into Lumia smartphones, Mountain View based Pelican Imaging has just announced that Bo Ilsoe, member of the Nokia Growth Partners (NGP), will join their board of directors.
Nokia Growth Partners (NGP) Partner Bo Ilsoe has joined the Board of Directors of Pelican Imaging, the inventor of groundbreaking array camera technology for mobile devices.
