Commitsensor: camera_sensor_legacy/raw: Support separate H/V flips원본 열기 → raspberrypi/libcamera / Documentation/sensor_driver_requirements.rst / f99576198b
sensor: camera_sensor_legacy/raw: Support separate H/V flips CameraSensorLegacy and CameraSensorRaw support flipping on the sensor side only if the driver supports both, V4L2_CID_HFLIP and V4L2_CID_VFLIP. In cases where a driver only supports a single flip mode, flipping support gets disabled completely. This is unexp…

ipa: rkisp1: lsc: Resample polynomial lens shading tables at configure time The lens shading correction is always applied based on the sensor crop bounds. This leads to incorrect lens shading correction for analog crops that do not cover the whole sensor. To fix that, we need to adapt the lens shading table for the se…
