Dual Cameras on the Smartphone Can Completely Revolutionize Smartphone Imaging
Dual Cameras on a phone are coming. Plus they are really good. HTC's upcoming flagship, codenamed M8 is also rumoured to have a dual-camera smartphone. Corephotonics, an Israeli startup has revealed it's dual camera tech at MWC 2014. Having dual-cameras has many advantages besides capturing in 3D. Corephotonic's prototype has one fixed focus telephoto having a narrow field of view and yet another is a normal wide angle. With such two lenses together can dramatically increase photo quality while focusing speed. How To Unlock HTC One M8
So how exactly does it work, you ask? Well, the customized software algorithms around the prototype blogs about the images from the cameras,. pixel by pixel. It then determines which pixel is clearer in both the photos and also the clearer you are chosen for that final photo. By this, you receive the clearest possible photo, one which can better the 41 MP sensor from the Lumia 1020 while also being significantly smaller.

The narrow field-of-view camera shoots in black and white, so the resultant image has minimal noise. Don't be concerned, the ultimate photos is still in full-colour, as the other camera still shoots in colour. However, if a pixel from your Narrow Field-of-view sensor is clearer, it's chosen after which coloured using information in the other camera.
All this happens in realtime, without any discernible lag, which is because of the Qualcomm Snapdragon 800 chipset underneath doing the hardwork. The Snapdragon 800 was chosen, because Snapdragon's 800 series will be the only processors available in the market with two Image Signal Processors, enabling the chipset to get information from the cameras and process them simultaneously.
Because of information from 2 cameras, you are able to zoom in a little without any visible degradation of quality.
Another quirk of getting two cameras, is always that HDR shots are drawn in just one single shot, increasing speed significiantly. Other phones must take 3 different shots with varying exposures which adds up with time as well as introduces ghosting when there is even a slight movement.
As a result of having two cameras, acquiring focus lock is also fast and may take as litlle time as 100ms. While using two different cameras, the program can also be able to detect depth.
Corephotonics says their imaging tech can come in smartphones as soon as this coming year, since most of the various happen to be there on the market, with some modifications. The Qualcomm Snapdragon 800 is there in many with the flagships from 2013's 4th quarter and the cameras are simply modified Sony 13 MP cameras.
Corephotonics' tech can bring better made in the slimmer package unlike the Lumia 1020 with a bulky body. Corephotonics' prototype can be viewed better than the Lumia 1020.
