Periscope cameras are a way to provide long focal lengths in the slim form factor of a smartphone. But how do they work? A video that shows the disassembly of Oppo Reno camera could shed some light on that.
The periscope module measures only 23.5 x 11.5 x 5.73mm. Its thin enough that it can fit into phones without creating a major hump. Its quite small overall, so it doesnt take up too much of the internal volume.
The module consists of three main parts: prism, lenses and sensor. The lenses come out as a unit, they are a special D-Cut design that helps keep the module as thin as it is. A magnetic coil moves the prism to achieve optical image stabilization.
The main wide-angle camera of the phone also has OIS, but this is traditional design. You can see both stabilization systems side by side at 2:15 in the video. The two cameras can work together to achieve 10x hybrid zoom.
Wed love to see a disassembly of Oppo Renos selfie camera too its a pop-up camera with a unique design.
