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.
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).
