Dual cameras

A competitor to Apple-acquired camera tech firm LinX has demonstrated the benefits that can be delivered by a twin-camera system like that rumored for the iPhone 7 Plus. A CNET video (below) shows how combining images from two separate cameras can deliver far sharper zoomed-in images compared to the camera in the iPhone 6s/Plus.

Corephotonics said that it had working dual camera systems back in 2014, but the supply chain was not yet able to deliver the volumes needed. That has now changed, it says …

We asked you yesterday to tell us how exciting you found the possibilities opened up by Apple’s patent for twin rear-facing cameras, and the results were very clear: 70.4% of you selected either ‘very exciting’ or ‘take my money.’

In addition to the possible applications I outlined in the piece, some of you had additional ideas that might be made possible by the dual-camera tech which has been rumored for the iPhone 7 …

We heard a report in November that Apple was testing an iPhone 7 model with dual rear cameras, and a patent application published today not only confirms that Apple is indeed exploring the idea, but reveals some extremely exciting possibilities with such a setup.

By fitting two separate camera modules behind the lens, and creating a single lens with both standard and telephoto sections, you’d be able to switch between two different focal lengths. For the first time, you’d be able to take a zoomed-in photo without cropping away pixels to end up with a lower-resolution image.

But the possible applications described in the patent go way beyond this …
