Samsung files a patent application for a dual-camera system

The patent application is titled “Digital Photographing Apparatus and Method of Operating the Same”, and shows a system of two cameras – one with a wide-angle lens and one with a telephoto lens. The latter would capture a zoomed-in image of the subject that's being shot, and a processor would be used to determine which of the two cameras is capturing the “main image”, based on the subject's motion.
Additionally, the application describes a possibility where both camera images are displayed on the device's screen, with the main image being displayed full-screen, while the sub image is shown as a picture-in-picture on top of it.
It is unknown if and when the dual-camera system will make its way to a Samsung smartphone, but it's definitely worth keeping our eyes open for any new info on the subject.
