Nokia Invests in Mobile Camera Firms in Bid to See Like a Bug

Pelican's lenses also allow for slimmer form factors
may be a fresh face on the market, but it drew lots of attention with its plenoptic imaging technology, which uses software to stitch together input from multiple small lenses into a single cohesive image.
The resulting image not only rivals images taken from larger lenses, it also allows for dynamic adjustments to the focal length. In many ways the multi-lens technology mimics nature -- insects see the world through multiple lenses, but their brain is thought to act as an image processor, stitching these images together into a single scene.
Now Finnish Windows Phone-maker Nokia Oyj. (
) has made a invest in Pelican worth up to $15M USD, hoping that the imaging firm's expertise can help it to beat out Android phonemakers and Apple, Inc. (
) in smartphone imaging.
Nokia is already very focused on imaging; its PureView smartphone -- which will soon receive
a Windows Phone makeover
can take 41 megapixel shots
. Nokia has been among the companies aggressively pushing high dynamic range (HDR) imaging as a means to improve smartphone camera image color.
Shipments of Nokia's smartphones
doubled on a YoY (year-to-year) basis
, but the phonemaker still
only accounts for 3 percent
of total global smartphone sales. Plenoptic imaging could help it win customers who are obsessed with taking the perfect smartphone image.
Describes Bo Ilsoe, a partner at Nokia Growth Partners, "[Plenoptic imaging] is on the cusp of being commercialized and Pelican does software for that. It’s very complicated to do this algorithmically and Pelican is one of the companies that has mastered this technology.

Nokia Growth investments are typically around $4M to $7M, and are capped at $15M USD. Pelican's other investors include Globespan Capital Partners, Granite Ventures, InterWest Partners, and Invesco Quality Muni Inv Trust (
Nokia's fund also invested in
, a Menlo Park, Calif.-based quantum dots imaging firm who looks to make smartphone sensors with the fresh nanotechnology, and Singapore-based lens-maker
. The Heptagon investment is particularly interesting as it is a startup that makes micro-optics. In other words, you could combine Heptagon's tiny lenses with Pelican's software to potentially make a full plenoptic smartphone imaging sensor.
Such a sensor could not only allow better images and more post-processing, but is also expected to be slimmer than a traditional camera module, allowing for thinner smartphones.

RE: 41 MP

I've seen the phone before. It doesn't need 41MP even with that lens and it's ugly/bulky as sin. Maybe they should've called it a camera with phone as a feature.
APS-C sensors are usually 20MP or less and still get plenty noise above 1600 ISO. Most phone cameras shoot at high ISO(~800+) to compensate for the little amount of light it receives. The raw pic will have plenty of noise so there's a heavy dose of NR and post processing in each pic.
The multiple lens and sensors can work IF the software is perfect. It just take multiple pictures and overlay them to fill in the missing info of each pic. That will reduce noise and add more details. The software has to piece together and compensate for multi pics, pixels shifts, chromatic aberration and lens distortion of each, etc...
It is a colossal amount of post processing which will make it drain battery and be slow as molasses in January.

You're completely missing the point - it allows for a digital zoom that is actually useful... as well as the over sampling to reduce noise (which obviously works better the less you are zoomed).
This is tried and test tech, it works.
