The removable camera module
will house its own battery, as well as NFC, Wi-Fi and Bluetooth communication
Oppo has patented the original smartphone with a removable camera module. Images from the World Intellectual Property Office (WIPO) database allow you to understand how it all works.
In general, there is nothing complicated: a removable camera module with two lenses and two matrices is mounted in the recess of the back panel of the smartphone. It is connected via a USB-C port, but for wireless transfer of photos and videos, support for NFC, Wi-Fi and Bluetooth interfaces is provided by the module itself. Its autonomy is guaranteed by a built-in rechargeable battery.
As conceived by the developers, the smartphone can get by with one camera unit located on the rear panel. And if the user suddenly wants to take a selfie, then the module can be taken out and directed at himself or at any other subject. That is, in fact, such a camera turns into a kind of action camera. Moreover, taking into account current trends, the smartphone module has the advantage of built-in stabilization and optical zoom. True, it is hardly necessary to speak about protected performance here. And smartphones with such modules make it possible to hardware update the camera after purchase. For example, instead of a module with two sensors, you can install a module with three.
Naturally, registration of a patent does not at all guarantee the mass production of such a model. But this does not mean that such a smartphone has no chance of serial implementation.
