CamHelpers get virtual Prepare() and Process() methods, running just before and just after the ISP, just like Raspberry Pi Algorithms. The Prepare() method is able to parse the register dumps in embedded data buffers, and can be specialised to perform custom processing when necessary. The IPA itself only needs to call the new Prepare() and Process() methods. It must fill in the DeviceStatus from the controls first, in case the Prepare() method does not supply its own values.

libcamera for the Raspberry Pi
Raspberry Pi provides a fully featured pipeline handler and control algorithms (IPAs, or "Image Processing Algorithms") to work with libcamera. Support is included for all existing Raspberry Pi camera modules.
libcamera for the Raspberry Pi allows users to:
- Use their existing Raspberry Pi cameras.
- Change the tuning of the image processing for their Raspberry Pi cameras.
- Alter or amend the control algorithms (such as AGC/AEC, AWB or any others) that control the sensor and ISP.
- Implement their own custom control algorithms.
- Supply new tunings and/or algorithms for completely new sensors.
How to install and run libcamera on the Raspberry Pi
