This metric is derived from the ISP statistics block.\n\nThis set of changes adds a Figure of Merit (FoM) libcamera control that can be\nused for such situations. As a note, this is a singular value that\ngives a numeric score for how in-focus an image is, not a means to run an AF\nalgorithm. It is up to the IPA to calculate this score however it sees fit.\nThe Raspberry Pi averages the middle two regions in a 4x3 grid to start with.\nWe may change this later when we have adjustable regions.\n\nAs always, comments welcome.\n\nRegards,\nNaush\n\n\nNaushir Patuck (4):\n libcamera: controls: Add focus Figure of Merit (FoM) control\n libcamera: ipa: raspberrypi: focus: Fix for uninitialised variable\n libcamera: ipa: raspberrypi: Populate libcamera metadata after\n controller process\n libcamera: ipa: raspberrypi: Populate focus FoM from the ISP\n statistics\n\n src/ipa/raspberrypi/controller/focus_status.h | 2 +-\n src/ipa/raspberrypi/controller/rpi/focus.cpp | 2 +-\n src/ipa/raspberrypi/raspberrypi.cpp | 15 ++++++++++++++-\n src/libcamera/control_ids.yaml | 11 +++++++++++\n 4 files changed, 27 insertions(+), 3 deletions(-)"}
