Raspberry Pi Camera Module, Embedded IR-CUT, Supports Night Vision, Type B. After the Bullseye version of the Raspberry Pi image, the underlying Raspberry Pi driver was switched from Raspicam to libcamera. libcamera is an open-source software stack (will be called driver later, which is easy to understand), which is convenient for third-party porting and development of their own camera drivers. As of 2021-12-20, there are still many bugs in libcamera, and the current libcamera does not support python, so the Raspberry Pi official still provides a method for installing and downloading raspicam. For users who are difficult to switch to libcamera but need to use the latest system, please directly refer to the Raspicam instructions.
