Unfortunately I couldn't quite bring myself to do it as an\nint32_t control because it seems so similar to existing float controls\nlike contrast, or saturation. But if we'd rather go back to ints, as\npreviously suggested, just let me know and I'll redo the changes!\n\nThere are 3 small patches in this set:\n\n1. The first one just adds the \"sharpness\" control. This commit is\nthe only Raspberry Pi indpendent change (and doesn't even involve\nany C++ code).\n\n2. The second implements the control's effect in Raspberry Pi's\nsharpness control algorithm.\n\n3. The final patch just plumbs the two together.\n\nThanks and best regards\nDavid\n\nDavid Plowman (3):\n libcamera: add a sharpness strength control\n libcamera: raspberrypi: add sharpness strength control to Raspberry Pi\n IPAs\n libcamera: raspberrypi: plumb the libcamera sharpness control through\n to the Raspberry Pi implementation\n\n include/libcamera/ipa/raspberrypi.h | 1 +\n .../raspberrypi/controller/rpi/sharpen.cpp | 23 +++++++++++++++----\n .../raspberrypi/controller/rpi/sharpen.hpp | 6 +++--\n .../controller/sharpen_algorithm.hpp | 21 +++++++++++++++++\n .../raspberrypi/controller/sharpen_status.h | 2 ++\n src/ipa/raspberrypi/raspberrypi.cpp | 12 ++++++++++\n src/libcamera/control_ids.yaml | 11 +++++++++\n 7 files changed, 70 insertions(+), 6 deletions(-)\n create mode 100644 src/ipa/raspberrypi/controller/sharpen_algorithm.hpp" }
