Nokia patent for adjustable aperture could improve the camera on the next PureView device
A patent awarded to Nokia just might solve the problem that cellphone cameras currently have. Either they are great at taking pictures in daylight or in low-light with a flash like the Nokia 808 PureView, or they take great pictures in low-light with no flash. The latter is what we see with the Nokia Lumia 920. The reason why these cameras can only do one or the other has to do with the setting of the aperture.

The Nokia Lumia 920 takes great low-light photos without a flash because of its large aperture size of f/2.0. The outstanding daylight pictures taken with the Nokia 808 PureView are due to the f/2.4 aperture on that phone's camera. If a cellphone camera can be made to adjust the aperture, perhaps an OEM like Nokia could deliver a handset with a camera that can adjust from a low aperture for daylight or a landscape shot to a larger aperture for low light or portrait pictures.

"Small aperture with high f- number increases the sharpness of distant objects, or in other words increases depth-of-field, which means more elements of a picture, from foreground to background, become sharply focused. This can create a distinct sense of depth to a photograph, drawing the viewer into the picture. It is well-known that small apertures are used especially for most landscape photographs.

The large aperture produces shallow depth-of-field, which means the area of sharp focus in the picture will be small. It is well known that small apertures are used especially for isolating the subject of the picture while throwing the background and other distracting elements out of focus. Some useful applications of large apertures include portraits and wildlife close-ups."-Nokia


The technology involves using two electrodes, and an electrical circuit that applies voltage to the electrodes. In a nutshell, the idea is to use the current to squeeze an electroactive center unit which adjusts the aperture. Nokia also mentions that it looks to use its patent to make prior art versions of the technology less complex, easier to manufacture and consume less power.

Will we see this on the Nokia Lumia EOS when and if it ever gets announced?

Finally my old N86 with variable aperture is back.

But the problem is :

YES! I love Nokia EOS!

NO! I will never buy a Nokia anymore because of this retarded WP8!

Even you said WP8 is retarded (and im a user), i thumbed you up. Frankly speaking, i dont miss Symbian at all after moving to WP8, with an android phone as my 2nd device. Performance and smoothness is leaps and bounds ahead. Maybe i wished there is a file manager but i can live without that.

As for the camera department i know Nokia always delivers, so i can wait. N86 is probably the only phone which had adjustable aperture on its camera, but sadly it uses LED flash instead.

Too bad the only retard is the one who hasn't used WP8.
I'll never use iOS or go back to Android. There are a few apps and customizations I liked on Android but its buggy... I think now I'm down to 1 app that I don't have on wp8 that I had on Android.

I have the new iPad and the Nokia Lumia 920. The best combination of devices. The best tablet in market and the best durable cameraphone (a phone has to survive daily use in work) with a very intuitive OS.

Because their phones ARE cameras.

Because they are extremely good at a niche area of photography...miniaturization with relatively hi performance.

Nobody buys a camera these days. Regular consumer buys a good quality cameraphone which is always in a pocket. Professionals are different story.

oh that's why Nokia 920 pics in low light are great and are not so good as competitor's. in normal conditions.
adjustable aperture will overcome this problem.
go Nokia show the world preview phase 3

No, that's not the reason, because competitors do NOT have adjstable aperture as well.

Except OEM:s like HTC are already busy thinking how they can steal Nokia innovation. "Lets copy tech and call it ultradjustable aperture!".

HTC - Silently stealing

Mails, calendar, appointments, social networking, notes and some office/pdf documents; everything very manageable on 3.5", let's say 4-4".
Have I forgotten something a smartphone is made for?

the problem with nokia is they stack with windows and even if they release one or two Android devices it will only be on one carrier at&t exculsives so its hard for them to sell more than the others.

Nokia will never use Android. How come Nokia use Android and Android paying for windows patent! plus the windows 8 phones it's more smother than any Android phones in the market including S4.

I have 808, and i only use it to take photos..but my note2 is good enough in camera atlz in daylyt and macro shots so my 808 mostly on nytshft job hehe. ;)
I cant 4get abt android, it is my top choice, cant live a smartphone life w/o android haha

As I could see, 808's camera software is quick and good; if you use the device only for it's camera, you won't be bothered by browser speed or by the inability to install... don't know, Instagram or Temple Run.
A good comparison would be between 808 and Samsung [some name] camera.

The second bad choice you have made is choosing a tiny tablet - Note - instead of 7-10" one.

Everyone can live without Android; if one wants the best smartphone, one chooses iPhone; if one wants a very good and cheaper alternative, one chooses Windows.

See, no Android.
