\brief Retrieve the model name of the device The model name allows identification of the specific device model. This can be used to infer device characteristics, for instance to determine the analogue gain model of a camera sensor based on the sensor model name. Neither the V4L2 API nor the Media Controller API expose…

Commitlibcamera: property_ids_core: Drop PixelArrayOpticalBlackRectangles원본 열기 → raspberrypi/libcamera / src/libcamera/property_ids_core.yaml / 61b60d215b
libcamera: property_ids_core: Drop PixelArrayOpticalBlackRectangles The PixelArrayOpticalBlackRectangles is neither used nor populated anywhere in libcamera. The definition of it is difficult (due to the handing of invalid pixels and sensors specifying different OB areas for different binning modes) and will therefore break on the first real world use-case. Drop it for now. This can be revisited …

libcamera: sensor: Add Mira220 sensor properties Add sensor properties for the AMS-OSRAM Mira220 camera sensor. The sensor has a 1 frame delay for exposure. The vblank delay is not characterized in the datasheet. Hblank and analogue gain are fixed and not programmable, so fix their delays to 1. Signed-off-by: Jacopo M…
