The AF mode behaviors are described as follows.\n\n1. Auto mode\nThe AF result is not sensitive to the change in the image variance so if\nthe algorithm finds the focus, and the focus will be persisted until the\nvariance is significantly changed.\n\n2. Continuous mode\nThe AF result is highly affected by the change in image variance. The\nfocus result will be changed according to the environment immediately.\n\n3. Manual mode\nThe user is allowed to set the lens position.\n\n\nKate Hsuan (3):\n ipu3: Registering AF controls\n ipa: ipu3: Drive requestQueue when controls are accepted\n ipa: ipu3: af: AfMode and LensPosition control implementation\n\n src/ipa/ipu3/algorithms/af.cpp | 106 +++++++++++++++++++++++----\n src/ipa/ipu3/algorithms/af.h | 15 ++++\n src/ipa/ipu3/ipu3.cpp | 7 ++\n src/libcamera/pipeline/ipu3/ipu3.cpp | 2 +\n 4 files changed, 114 insertions(+), 16 deletions(-)" }
