Samsung Electronics recently filed for a patent for a mobile dual camera configuration in South Korea. The company's invention consists of a wide angle lens complemented with a telephoto lens. While the wide angle lens is used for regular image capture and area scanning, the telephoto one is activated whenever the camera is trying to record a photo with multiple subjects located at various distances from the primary lens. In theory, this solution allows users to change zoom and other settings and even move without losing focus. Additionally, Samsung's invention theoretically enables capturing of extremely sharp pictures that otherwise wouldn't be possible to record without resorting to extremely narrow apertures or post-processing techniques which rely on combining multiple images. Of course, the main advantage of this solution is that it does everything in real-time.
The recently leaked patent documentation reveals that Samsung envisioned the wide angle lens as a trigger for the telephoto lens in this configuration. In other words, the former scans any image and activates the latter whenever it's unable to focus on an object without losing focus of the background. Samsung's documents suggest several useful applications of this technology like shooting extreme sports and other scenarios in which a user is expected to capture quickly moving subjects. All applications outlined in Samsung's latest patent filing can be seen in the gallery below.
This filing appeared online only a couple of months after Samsung submitted a request to patent a particular camera user interface whose design seems suitable for devices boasting a dual camera configuration. The South Korean tech giant has long been rumored to include a dual-lens rear camera in its upcoming Galaxy S8 flagship, though the company is still doing a good job of keeping its next phablet under wraps. A dual camera system would allow the company to easily improve on the camera featured in the Galaxy S7 and the Galaxy S7 Edge without shipping a device with a camera bump. Naturally, this solution would likely only be reserved for high-end devices with premium price tags. The Galaxy S8 is expected to debut by April, so more information on Samsung's plans for the future of mobile camera technologies should follow shortly.
