When was the last time you carried around a 2nd device for taking pictures? No need! Phones now come equipped with cameras. With all these advances in camera phone technology, point and shoots just aren’t as important as they used to be. There is still lots of room for innovation in mobile phone cameras. Here are two recent innovations.
Turning a camera phone into a microscope article tells that researchers at the VTT Technical Research Centre in Finland have developed an optical plastic lens accessory that can turn an ordinary camera phone into a microscope with a resolution between 6-10 microns. A new Finnish start-up called KeepLoop (Tampere, Finland) is already exploring the commercial potential of the invention (first products expected this spring).
Nokia announces camera phone with 41 megapixel sensor. Nokia has history of making best camera phones. Video and movie shooting with a smartphone tells how N8 phone has been used to shoot full lenght movie. Now Nokia has made a nice successor to N8. Nokia recently announced 808 PureView: Belle OS, 4-inch display and 41-megapixel camera. It has a sensor resolution of over 41-megapixels when shooting stills — or 34-megapixels for 16:9 images. One of the key advantages is it lets you zoom in three or four times in either photos or video and still have a sharp image with many megapixels resolution. Nokia said it can create a better five-megapixel image by using the data in the seven extra pixels to inform which single pixel it uses. It’s not about the amount of the pixels, it’s what you do with them.
Nokia 808 PureView – How good can a pixel be? video is a look at the technology involved and some sample shots taken with Nokia’s freshly minted 808 PureView imaging powerhouse .
If it were easy to put a decent zoom lens in a camera phone, Nokia might never have come up with its biggest breakthrough in mobile phone imaging in years. It has been difficult it is to achieve good optical zoom performance in smartphones. The lens must be very tiny to fit inside phone, so lenses lets very little light in and their structure is very complex and hard to manufacture.
Nokia 808 PureView ushers in a revolution in smartphone imaging: The Nokia 808 PureView features a large, high-resolution 41 megapixel sensor with high-performance Carl Zeiss optics and new pixel oversampling technology. The Inside Story of Nokia’s 41-Megapixel Camera Phone: Five Years in the Making article tells the the development team inside Nokia had been working on the technology in secret for the last five years. “We were aware that it is possible to do zooming by very high resolution image sensor, but the idea of putting such a large and high resolution image sensor into a smartphone felt completely crazy,” Alakarhu said. “That was five years ago, and I guess it still feels like that.” One of the key advantages is it lets you zoom in three or four times in either photos or video and still have a sharp image. Finnish articles Zoomissa miehet Nokia Pure View –teknologian takana and Nämä miehet – Eero ja Juha – Nokian kamerahirviön takana give some more details on the invention and men behind the invention.
Nokia 808 PureView’s primary selling point: it’s a phone for camera enthusiasts. In many ways, Nokia’s phone more closely rivals a point-and-shoot camera in size than a smartphone. Let’s say bye to point and shooting cameras! Expectations of the future sales price of this camera-phone will be 450 euros (without taxes).
How camera makers are getting their design groove on
http://news.cnet.com/8301-11386_3-57517481-76/how-camera-makers-are-getting-their-design-groove-on/
A wave of experimentation is sweeping the camera industry as it grapples with the second phase of the digital revolution. Be careful: today’s bold design could be tomorrow’s evolutionary dead end.
Ecosystem wars
Cameras have long had an ecosystem element of their own: the proprietary lens mount used to attach lenses to camera bodies.
The smartphone crisis
For ordinary people, the biggest change in photography is the arrival of smartphones with respectable if not stellar cameras. Early phone cameras suffered from dismal image quality and performance, but each passing year has shown improvements in resolution, low-light performance, lens quality, and speed. And as the smartphone market has expanded, more people get access to those capabilities.
Because people always carry their phones, those cameras are the ones increasingly used to document people’s lives photographically. As the phones’ cameras improve, there’s less and less reason to carry a regular camera even for special occasions. And that’s just the first reason camera makers need to be worried.
The second is that people do things with their smartphone photos — post them to Facebook, edit and share them with Instagram, annotate Evernote documents, digitize business cards so contact information is synchronized with the cloud, feed them into Google to translate a sign in a foreign language. That’s all possible because smartphones, unlike most cameras, are connected to the Internet.
But wireless networking in the camera industry in general has been conspicuous by its absence, isolating cameras from people’s in-the-moment sharing activities.
Apple Acknowledges iPhone 5 Camera Problem, Says You’re Holding It Wrong
http://gizmodo.com/5947972/apple-acknowledges-iphone-5-camera-problem-says-youre-holding-it-wrong
Some photography experts have speculated that the purple flare is a product of the sapphire glass covering the iPhone 5’s camera.
So it is final, folks: Apple says that, if your photos have a purple flare, this is totally normal behavior of the iPhone 5’s camera. You are just holding it wrong.
Their solution: “Angle the camera away from the bright light source when taking pictures.”
Kaspersky adds mugshot feature to Mobile Security software

Kaspersky said it also remains possible to control the device remotely via special SMS based commands, along with the SIM Watch function that offers an alternative method of remote control.
DxOMark Mobile first quick glance: Smartphones beat 5-year-old DSCs
http://www.dxomark.com/index.php/News/DxOMark-news/Smartphones-beat-5-year-old-DSCs
What is the best cameraphone available on the market? Does the incredible Nokia 808 PureView sensor mean the end of the DSC era? How fine are full HD videos shot with your smartphone compared to DSC’s ones? Here are our answers
Is a smartphone worth using as a digital still camera?
Nokia has blown all of these specifications out of the water with its new, bulky, 41-megapixel Nokia 808 PureView.
But shrinking and squeezing more megapixels onto a sensor’s surface does not necessarily translate to better image quality. Smaller pixels and their reduced area-size absorb less light, which consequently leads to a reduction in their signal-to-noise ratio, often leading to noisier images
Many mobile devices address noise through their imaging filters and processors. But tamping down noise frequently leads to other image defects, such as loss of detail and texture
The best smartphone on the market for shooting still images takes better photos than a 5-year-old high-end compact
Yes, the implausible 41-MPix Nokia 808 PureView sensor is fulfilling its promise, but let us reassure you that it is not outperforming the new generation of DSCs, and that there is a long way to go to attain DSLR image quality (as shown in the following graph):
For taking awesome videos, the best mobiles have an incredible advantage over quite recent DSCs
The full HD videos of the Samsung Galaxy SIII, the best smartphone DxOMark Mobile has tested so far, are truly impressive, with better quality than those of the Canon Powershot S100
Apple patent could remotely disable protesters’ phone cameras
http://www.zdnet.com/apple-patent-could-remotely-disable-protesters-phone-cameras-7000003640/
Summary: A new patent, granted to Apple, could prevent academic cheating, cinema interruptions, but also see areas of political protest activity ‘ring-fenced’ disabling phone and tablet cameras.
Isn’t it a shame you can’t take a photo of the police officer beating a man in the street because your oppressive government remotely disabled your smartphone camera?
A new patent granted to Apple could do all of the above.
U.S. Patent No. 8,254,902, otherwise known as “Apparatus and methods for enforcement of policies upon a wireless device,” was granted in late-August, and would allow phone policies to be set to “chang[e] one or more functional or operational aspects of a wireless device [...] upon the occurrence of a certain event.”
What that means in real-terms is “preventing wireless devices from communicating with other wireless devices (such as in academic settings),” and for, “forcing certain electronic devices to enter “sleep mode” when entering a sensitive area.”
But the patented technology may also be used to restrict protesters’ right to free expression in oppressive regimes around the world — if you haven’t checked recently, there’s plenty of them — by preventing camera images and video being taken at political rallies and events.
It’s clear that although Apple may implement the technology, it would not be Apple’s decision to activate the ‘feature,’ such as a remote-switch — it would be down governments, businesses and network owners to set such policies.
Those policies would be activated by GPS, and Wi-Fi or mobile base-stations, which would ring-fence (”geofence”) around a building, a protest, or a sensitive area to prevent phone cameras from taking pictures or recording video.

New Video Breaks Down How An Apple Patent Stomps All Over The 1st Amendment
A patent granted to Apple in late-August allows governments to disable iPhones and other smartphones, targeting specific apps even, when they enter what is deemed a “sensitive” area.
U.S. Patent No. 8,254,902, titled “Apparatus and methods for enforcement of policies upon a wireless device,” enables phone policies to be set to change “one or more functional or operational aspects of a wireless device … upon the occurrence of a certain event.”
Camera? Off. Voice recorder? Off. No calls out, no calls in. Total blackout; or, for an event like a concert, the organizers could target specifically just recording functions of a user’s phone.

How to make & view 3D Stereograms with your iPhone
http://www.instructables.com/id/How-to-make-view-3D-Stereograms-with-your-iphone/
A Stereogram is an image that can be perceived with depth perception via one of several viewing techniques. This is the basis of 3D imaging and is in essence assisting one eye to see one image and the other to see a slightly different image.
Naked-eye Stereogram viewing can be a lot of fun and is made much easier to learn with this viewing assistant. After a bit of practice you might be able to view the 3D image without the viewer at all by using the same cross-eyed to uncross-eyed technique explained in this tutorial.

Time published a cover photo taken on iPhone
A well-known weekly magazine Time has used the cover image of the iPhone 4S smart phone images taken by Hurricane Sandy.
The cover was taken by the photographer Ben Lowyn, who says that smartphone cameras can overcome the traditional in many ways.
Even if Lowy is good with smartphone with a camera, he said, many professional photographers see him as an amateur or as a tourist.
Lowy carries two iPhones, Mophie Juice Pack accessories Manfrotto battery and LED light.
Lowy would like to see better low-light shooting capabilities, adjustments to shutter speed and aperture. Still, the smartphone has a camera in her tool of choice.

Nokia’s important camera guru switched to a car manufacturer
Camera technology is Nokia’s main selling points for the smartphone market. The company is a great loss when the camera long driven the development of Damian Dinning leave the company. He moves suddenly, a car manufacturer Jaguar Land Rover. Dinning is completed by two simple reasons.
Damian Dinning came to Nokia in 2004. He brought a Nokia camera-important field of expertise. Dinning had previously worked with such as Minolta and Eastman Kodak.
Dinning, Nokia has developed an excellent camera unit. In recent breakthroughs such as PureView camera that brought the smartphone up to 41-megapixel image sensor.
Damian Dinning says PureViewClub-release , that he would not have wanted to leave Nokia. Reason for this situation is the fact that Nokia will focus on the key personnel to the company’s head office in Finland. Dinning says that his family situation at the moment does not allow it.
He says that in addition to photography from an early age he has had another great interest: cars. So he takes the opportunity to work in this area.

Cell phone camera detects allergens in food
http://www.vision-systems.com/articles/2012/12/cell-phone-camera-detects-allergens-in-food.html?cmpid=EnlVSDDecember272012
Food allergies are an emerging public concern, affecting as many as eight percent of young children and two percent of adults. While consumer-protection laws regulate the labeling of ingredients in pre-packaged foods, cross-contaminations can still occur during processing, manufacturing and transportation.
A team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science (Los Angeles, CA, USA) has developed a lightweight device called the iTube which attaches to a common cell phone to detect allergens in food samples.
The iTube attachment uses the cell phone’s built-in camera, along with an accompanying smart-phone application that runs a test with the same high level of sensitivity a laboratory would.
[...] and video 2013 Cell phones with build in cameras are replacing cheap pocket size digital cameras and video cameras. Best cell phone cameras can be better in many ways than cheap pocket digital cameras from few years [...]
Even as cameras in mobile devices have improved in resolution and performance, they have been stymied by the form-factor limitations that are inherent in the devices themselves. However, the increase in available computational power offers a solution: that is, to process the images from the camera in novel ways to match the capabilities of dedicated cameras, and also exceed those capabilities by performing new ways of image capture that cannot be accomplished with traditional cameras

Computational Photography is an emerging new field created by the convergence of computer graphics, computer vision and photography. Its role is to overcome the limitations of the traditional camera by using computational techniques to produce a richer, more vivid, perhaps more perceptually meaningful representation of our visual world.

Today, smartphone cameras are quite sophisticated. The picture quality in when picture is taken on good lighting conditions can be hard to see different than what you get with DSLR or picket digital camera.
You can take good pictures with cell phone camera when you understand its weaknesses. Since the image sensor is a small recorders, mobile phones have poor low light performance.
Another small-cell-induced feature is the large depth of field. The entire image area is sharp (you can’t blur the background as with DSLR at wide apertures).
Small cell phone cells are usually able to focus very close to your subject.
A number of smart phones have digital zoom that does not change the focal length of the lens, just crops the image. Instead of using zoom get more near to subject.
You should keep in mind good weather and light when shooting with a mobile phone. At bright day cell phone camera performs well, but keep in mind that cell phone cameras have usually weaker dynamics than bigger cameras.
In the morning and at dusk bigger cameras perform considerably better than mobile phones. Smartphones, cameras, small cells are vulnerable to problems in low light. When flash is used the images tend to look unnatural.

Nokia to bring 41-megapixel ‘Pureview’ sensor system to Lumia range
http://www.guardian.co.uk/technology/2013/feb/04/nokia-pureview-sensor-coming-lumia
The oversampling system brought to Nokia’s last Symbian phone during 2012 will be coming to its Windows Phone Lumia range soon, the Guardian has learned
Nokia is finally bringing its “revolutionary” 41-megapixel Pureview sensor to its Lumia range of Windows Phone handsets, according to sources close to the Finnish handset maker.
The new model will be known as EOS, and will launch in the summer in the US.
The 41MP sensor debuted at the Mobile World Congress trade show in Barcelona in February 2012 on Nokia’s final Symbian phone, the 808.
Lumia 920 doesn’t have the 41MP sensor, but does have what Nokia calls “floating lens technology”: a gyroscope detects shaking such as uneven hand motion and the whole camera mechanism moves to compensate, so the shutter can be open for longer in low light. Results from the Lumia 920’s 8.7MP pixel in low light are certainly pretty good – in most low-light situations you don’t need the rather harsh xenon flash
Adding the 41MP Pureview sensor to the Lumia range would certainly put some distance between Nokia and its Windows Phone rivals HTC and Samsung.
I had been very pleased to find this kind of web-site.I wanted for you to thanks for your period because of this wonderful examine!! My partner and i definitely enjoying every little this and i also maybe you have bookmarked to view brand new issues you blog post.
Nokia Invests in High-Resolution Cameras to Woo Apple Customers
http://www.bloomberg.com/news/2013-04-29/nokia-invests-in-high-resolution-cameras-to-woo-apple-customers.html
Nokia Growth Partners, the venture- capital arm of Nokia (NOK1V) Oyj, plans to invest in California startup Pelican Imaging as the phonemaker seeks to win back customers from Apple Inc. (AAPL) and Android devices with cameras that give greater depth and ease of splicing together images.
The Pelican investment is part of a push to differentiate Nokia as it tries to stimulate demand in its Lumia smartphones, which run Microsoft Corp.’s Windows software, to reverse falling sales and recover market share.
Lumia sales rose to 5.6 million in the first quarter, up from 4.4 million in the previous three months. Still, Apple and Android-based devices control more than 90 percent of the smartphone market
Array cameras, which use multiple optics and mesh the data into one image, “are on the cusp of being commercialized and Pelican does software for that,” Bo Ilsoe, a partner at Nokia Growth Partners, said yesterday in a phone interview from California. “It’s very complicated to do this algorithmically and Pelican is one of the companies that has mastered this technology.”
Nokia, which bought Lund, Sweden-based imaging-software maker Scalado last July, released the 41-megapixel 808 PureView last year and is incorporating the technology in smartphones including the flagship Lumia 920.
Nokia reportedly investing in Lytro-style array camera startup
http://www.theverge.com/2013/4/30/4285044/nokia-plans-pelican-imaging-array-camera-investment-says-bloomberg?utm_source=feedly
Nokia is eyeing an investment in Pelican Imaging, a California startup working on array camera technology for smartphones, according to Bloomberg. Array cameras offer similar benefits to Lytro’s light field technique, allowing photographers to adjust an image’s focus after it has been captured, but use a single self-contained module with multiple optics.
“It’s very complicated to do this algorithmically and Pelican is one of the companies that has mastered this technology,” said Bo Ilsoe of Nokia Growth Partners, who added that the venture capital group has been watching Pelican since its founding in 2008.
Pelican Imaging has developed an innovative new array camera for mobile devices, providing depth at every pixel.
