Yesterday’s announcement of the all-new HTC One M8 brought the world the first mobile device with dual camera modules on the rear. The secondary camera in the HTC One is used for receiving depth information, which can be used to selectively edit the foreground and background in an image after it was taken. Now, it seems like dual cameras could be the new trend, as Apple has applied for a patent (recently published by the U.S. Patent and Trademark Office) for such a technology, albeit one that is different from HTC’s.
In the patent application that was originally filed back in 2012, Apple describes an electronic device featuring two adjacent camera sensor modules, one that captures brightness information exclusively, and one that captures color information exclusively. The data captured by each sensor would then be combined to form a single photograph (or, as is safe to assume, video.)
This way, per the patent description, mobile devices could be built much slimmer, as the individual camera modules can be made smaller as compared to regular camera units for mobile devices. The question is, how much slimmer are smartphones and other mobile devices going to get? And will we see such a dual-camera technology in the iPhone 6 or iPhone 7? Could Apple combine this technology with its other patent for Lytro-like refocusing? Only time will tell.
In any case, it’s an interesting idea to separate brightness and color information capturing from each other. For those who’d like to dig deeper into the technicalities of this patent, the full patent description can be found here as a PDF file.
