Many\nsensors have either a fixed black level, or the current sensor kernel\ndriver sets a fixed value. It therefore makes sense to keep that\ninformation inside libcamera. When the need arises to be more flexible\nwe can extend the sensor drivers to report black level information. This\nseries adds black level support to the camera sensor helpers and the\ncorresponding metadata to the rkisp1 ipa.\n\nMy tuning series will be rebased on top of this one.\n\nBest regards,\nStefan\n\nStefan Klug (5):\n ipa: libipa: Add black levels to camera sensor helper\n ipa: rkisp1: Move camHelper into IPAContext\n ipa: rkisp1: blc: Query black levels from camera sensor helper\n ipa: rkisp1: blc: Report sensor black levels in metadata\n ipa: rkisp1: data: Update tuning files for imx219 and imx258\n\n src/ipa/libipa/camera_sensor_helper.cpp | 18 ++++++++++\n src/ipa/libipa/camera_sensor_helper.h | 6 ++++\n src/ipa/rkisp1/algorithms/blc.cpp | 47 ++++++++++++++++++++++---\n src/ipa/rkisp1/algorithms/blc.h | 5 ++-\n src/ipa/rkisp1/data/imx219.yaml | 4 ---\n src/ipa/rkisp1/data/imx258.yaml | 1 +\n src/ipa/rkisp1/data/uncalibrated.yaml | 1 +\n src/ipa/rkisp1/ipa_context.h | 4 +++\n src/ipa/rkisp1/rkisp1.cpp | 26 +++++++-------\n 9 files changed, 89 insertions(+), 23 deletions(-)"}
