I could not extract the black level from the AIQB\nbinary, so leave it as auto-detected at runtime.\n\nAs for the each row of the CCMs summing to 1.0, you are absolutely\nright. I add a test on a patch, before we start adding more\ntuning files.\n\n src/ipa/simple/data/meson.build | 1 +\n src/ipa/simple/data/ov01a10.yaml | 55 ++++++++++++++++++++++++++++++++\n 2 files changed, 56 insertions(+)\n create mode 100644 src/ipa/simple/data/ov01a10.yaml","diff":"diff --git a/src/ipa/simple/data/meson.build b/src/ipa/simple/data/meson.build\nindex 92795ee4..e6110320 100644\n--- a/src/ipa/simple/data/meson.build\n+++ b/src/ipa/simple/data/meson.build\n@@ -1,6 +1,7 @@\n # SPDX-License-Identifier: CC0-1.0\n \n conf_files = files([\n+ 'ov01a10.yaml',\n 'uncalibrated.yaml',\n ])\n \ndiff --git a/src/ipa/simple/data/ov01a10.yaml b/src/ipa/simple/data/ov01a10.yaml\nnew file mode 100644\nindex 00000000..fa5afcdd\n--- /dev/null\n+++ b/src/ipa/simple/data/ov01a10.yaml\n@@ -0,0 +1,55 @@\n+# SPDX-License-Identifier: CC0-1.0\n+%YAML 1.1\n+---\n+version: 1\n+algorithms:\n+ # Black level is not specified in the AIQB calibration binary; auto-detected\n+ # from the histogram dark end at runtime.\n+ - BlackLevel:\n+ - Awb:\n+ maxGainR: 2.5\n+ maxGainB: 3.2\n+ speed: 0.25\n+ - Ccm:\n+ ccms:\n+ - ct: 2856\n+ ccm: [ 1.1248, 0.2210, -0.3458,\n+ -0.4616, 1.7736, -0.3120,\n+ -0.4342, -0.9348, 2.3690 ]\n+ - ct: 3000\n+ ccm: [ 1.5839, -0.4188, -0.1650,\n+ -0.3670, 1.6565, -0.2895,\n+ -0.1213, -1.0442, 2.1655 ]\n+ - ct: 3450\n+ ccm: [ 1.6411, -0.5127, -0.1284,\n+ -0.3680, 1.6337, -0.2657,\n+ -0.1384, -1.0869, 2.2253 ]\n+ - ct: 4000\n+ ccm: [ 1.5414, -0.4024, -0.1390,\n+ -0.3304, 1.6352, -0.3048,\n+ -0.1237, -0.6699, 1.7936 ]\n+ - ct: 4150\n+ ccm: [ 1.7334, -0.6629, -0.0706,\n+ -0.3121, 1.6267, -0.3146,\n+ -0.0920, -0.9183, 2.0103 ]\n+ - ct: 5000\n+ ccm: [ 1.5015, -0.3165, -0.1850,\n+ -0.2277, 1.6190, -0.3913,\n+ -0.0699, -0.7285, 1.7984 ]\n+ - ct: 6500\n+ ccm: [ 1.8163, -0.7062, -0.1100,\n+ -0.1640, 1.5736, -0.4096,\n+ -0.0084, -0.8294, 1.8378 ]\n+ - ct: 7500\n+ ccm: [ 1.8953, -0.7980, -0.0973,\n+ -0.1539, 1.6001, -0.4462,\n+ -0.0101, -0.7800, 1.7902 ]\n+ - Adjust:\n+ gamma: 2.2\n+ contrast: 1.0\n+ saturation: 1.0\n+ - Agc:\n+ exposureTarget: 1.4\n+ hysteresis: 0.5\n+ stepDenominator: 20\n+...\n","prefixes":["v2","3/9"]}
