Samsung is expected to include a dual camera in its upcoming Note 8 flagship, and a division within the company just revealed some impressive details about what to expect.
There will be four main features of the dual sensors: zoom, perspective, low-light and depth.
Zoom will utilize the second sensor to optically zoom in up to 3x. The demo images show off the impressive range the camera can zoom in without distorting the image. From the demo shots shown off, you can see a subject (a sign outside the Samsung offices) shot straight on. But after a perspective mode is used, the image looks as if it has been taken at a slight angle.
