Xiaomi is reportedly working on a new implementation of a moving camera system in future smartphones, which will improve wide angle photography. The proposed solution is this arrangement of two cameras, which are located on a movable plate and which will be able to change the viewing angles of these cameras. The two photos, from the two cameras, can then be merged into a wider angle photo.
The truth is that adding moving parts to the smartphone is not the best, in terms of durability. The fall of the device can cause significant problems in them and in their layout.
