I adapted it a bit, as the\nstatistics on RPi are not the same, and I simplified it a bit, using\nonly one of the filters and all the regions (ie, it calculates a focus\non the scene, and not only on the center of this scene).\n\nThis is posted as a RFC, as it lacks a few things:\n- Kieran mentionned that the entityControls in the RPi pipeline handler\n should be emplaced into a map using an enum. I tried to do it, but I\n am no jinja2 expert, and it takes me too much time for something\n supposed to be easy :-). Help appreciated here (;-) ;-)).\n- The algorithm is not using any controls while David proposed those in\n [3]. I am planning to do it, at least to pass a region and send back\n the focus lens position but -ENOTIME yet.\n\nIn v2, I also included the namespace renaming, I wanted it in v1 but\nmissed it...\n\nDavid, Naushir, Laurent, Kieran, I am not sure about the copyrights and\nlicenses, please comment :-).\n\nThanks !\n\n---\n[1]: https://patchwork.libcamera.org/project/libcamera/list/?series=2969 \n[2]: https://patchwork.libcamera.org/project/libcamera/list/?series=2957\n\nJean-Michel Hautbois (4):\n ipa: RPi: Move the IPA to the ipa::RPi namespace\n ipa: raspberrypi: Introduce an autofocus algorithm\n libcamera: raspberrypi: Control the lens from pipeline\n ipa: raspberrypi: Control the lens position\n\n include/libcamera/ipa/raspberrypi.mojom | 1 +\n .../raspberrypi/controller/af_algorithm.hpp | 20 ++\n src/ipa/raspberrypi/controller/af_status.h | 31 +++\n src/ipa/raspberrypi/controller/focus_status.h | 3 +\n src/ipa/raspberrypi/controller/iob/af.cpp | 231 ++++++++++++++++++\n src/ipa/raspberrypi/controller/iob/af.h | 55 +++++\n src/ipa/raspberrypi/meson.build | 1 +\n src/ipa/raspberrypi/raspberrypi.cpp | 84 +++++--\n .../pipeline/raspberrypi/raspberrypi.cpp | 17 ++\n 9 files changed, 423 insertions(+), 20 deletions(-)\n create mode 100644 src/ipa/raspberrypi/controller/af_algorithm.hpp\n create mode 100644 src/ipa/raspberrypi/controller/af_status.h\n create mode 100644 src/ipa/raspberrypi/controller/iob/af.cpp\n create mode 100644 src/ipa/raspberrypi/controller/iob/af.h"}
