2023-09-27Documentation: Introduce Camera Sensor ModelJacopo Mondi
Introduce a documentation page about the 'camera sensor model' implemented by libcamera. The camera sensor model serves to provide to applications a reference description of the processing steps that take place in a camera sensor in order to precisely control the sensor configuration through the forthcoming SensorConfiguration class.
