I've moved them all up\n the file to the non-draft section.\n\n* We had a discussion about having a \"custom\" range, but I think the\n conclusion for the moment was not to add it. Please correct me if\n I'm wrong there.\n\n* The AfLensPosition control has gone. Instead LensPosition is defined\n to use a scaled \"dioptre-like\" kind of unit (hyperfocal distance\n divided by focal distance), so that 0 = infinity, 1 = hyperfocal,\n bigger numbers = closer.\n\n* The AfState has been reduced to just\n reset/scanning/focused/failed. It is expected that AfMode will be\n reported on every frame, and also the new AfPauseState which says\n whether CAF is running/pausing/paused.\n\n* I note that there's still some discussion elsewhere about the units\n for defining AF regions, and whether they need to have associated\n weights.\n\n* I haven't carried any tags over for now, I think things are still at\n a stage where everyone needs to review the changes, if that's OK!\n\nThe state transition diagram is cosmetically updated, but not\nmaterially different. It should be in the same place, but in case\nyou've lost the link:\nhttps://docs.google.com/drawings/d/1rU2nS82dEC8Y2eY0lKPkQQhd67gKLOl7PvSeUcL1j_E/edit?usp=sharing\n\nThanks!\nDavid\n\nDavid Plowman (1):\n libcamera: controls: Controls for driving AF (autofocus) algorithms\n\n src/libcamera/control_ids.yaml | 318 ++++++++++++++++++++++++++-------\n 1 file changed, 258 insertions(+), 60 deletions(-)"}
