Samsung Electro-Mechanics, the division of Samsung that develops smartphone camera modules, has posted a document that explains in detail how dual-cameras and related features and special modes work. The Note 8 is widely rumored to be Samsung's first dual-camera device, which makes it a safe bet to assume the online guide is referring to the upcoming model.

According to the document the camera module will feature a Super Night Shot mode that combines image data from both sensors for better low light performance, and a 3D Depth feature that uses depth data to blur the background of an image and lets you refocus after capture. There'll also be improved HDR processing and and a couple of depth-related special modes.

However, the most interesting part of the document compares image output from a 3x optical zoom to a digital zoom. Samsung calls the feature Smart Zoom, which could indicate that optical zoom is combined with some sort of intelligent digital zoom to achieve a 3x zoom factor, but we'll have to wait for the launch on the 23rd of August to get more detail.

In the meantime you can have a look at dual-camera guide on the Samsung Electro-Mechanics website for more information.
