Sadly my computer at work has had problems accessing some websites recently so I haven’t been able to post up a load of interesting information that I have read. So I have condensed a load of camera technology news (this time all from the brilliant Engadget website) into this one post. Enjoy!
Nokia has been investing in Pelican Imaging’s plenoptic camera system- which essentially uses 16 camera which each only capture with Red, Green or Blue colours and build up an image from that. This means there is less digital noise and also as the cameras have a slight distance between them it captures depth information to allow you to change the depth of field/focus position after the image has been taken. All of this information is stored in a JPEG file that is only 20% larger than standard! This post-focusing ability also means that the camera does not need to auto-focus and thus it is much smaller and quicker to use, making it perfect for smart phones. Check out the original article for more detailed information.
Researchers at the University of Illinois are looking to our eight-legged planet mates, not for mobility lessons, but as a reference for a new camera design. The system mimics the vision of bees and mantises by combining multiple lenses on a half hemisphere to provide a 180-degree view with a nearly infinite depth of field. The optics themselves are described as “soft, rubbery” and each individual microlens is paired with its own photodiode.
As you probably know Graphine seems to be the answer to many of the problems we currently face in technology, with this super material looking like it will massively improve everything from batteries to solar cells. But now add to the list camera sensors.
Researchers at the Nanyang Technological University have developed an image sensor made out of graphene that’s 1,000 times better at capturing light than traditional CMOS or CCD sensors, all while using 10x less energy. These new sensors may initially be used in surveillance equipment and satellites — when they do eventually end up in regular cameras, however, they’re promised to be five times cheaper than the sensors they’re replacing.
This material really will revolutionize our lives over the next couple of decades!
