After many stages, such as high pixel, large aperture, dual camera, super bottom, super long focus telescope, the camera arms race of the flagship mobile phone has not yet ended. However, not all users are shooting enthusiasts. For many users, the upgrade of mobile phone camera module is already "increasing power consumption and costs".

On December 7, it was reported that an OPPO removable camera patent appeared on the website of the World Intellectual Property Office (WIPO), showing a removable and replaceable camera module design.

In the patent drawing, there is a groove on the back of the mobile phone to hold the camera module. The camera module part has its own USB-C interface, which can be connected to the USB port of the mobile phone to be used as a self timer camera. This module even comes with its own battery, WiFi, Bluetooth and NFC, which can be used remotely independent of mobile phones, just like a sports camera.

Although the patent indicator only uses a simple camera module of dual camera+flash, as long as the manufacturer is willing, the "camera monster" module of multi camera or super bottom sensor has no technical difficulty. But how much the module will bulge depends on the manufacturer's accomplishments.

This kind of "single reverse lens" scheme has the advantage that the camera module can be used as both a front camera and an independent sports camera. Later, it can be upgraded independently or different modules can be purchased on demand. The disadvantage, of course, is the modular design, which will take up valuable space inside the fuselage. The main costs are getting thicker, heavier, and sacrificing endurance.

Although the shapes are different, the concept of OPPO is a bit like the vivo IFEA concept machine released by vivo in early October. The latter has an elevating front camera that is fixed with a magnetic suction. The front camera can be stored inside the body at ordinary times, and can be pulled out when necessary. It can be used as a sports camera "in vitro".
