Both sensors have an\nexponential gain model, which differs from the MIPI CCS exponential\nmodel in that the exponential factor is expressed in dBs instead of\npowers of two.\n\nPatch 1/4 prepares for exponential gain model support by reorganizing\ngain constants, and patch 2/4 implements the exponential model. It is\ncurrently restricted to a fixed linear factor (see patch 2/4 for\ndetails). Patches 3/4 and 4/4 then add support for the two sensors.\n\nLaurent Pinchart (4):\n libipa: camera_sensor_helper: Reorganize gain constants\n libipa: camera_sensor_helper: Implement exponential gain model\n libipa: camera_sensor_helper: Add IMX290 helper\n libipa: camera_sensor_helper: Add IMX296 helper\n\n src/ipa/libipa/camera_sensor_helper.cpp | 210 +++++++++++++++++-------\n src/ipa/libipa/camera_sensor_helper.h | 16 +-\n 2 files changed, 166 insertions(+), 60 deletions(-)" }
