A camera sensor has a 2-dimensional reference system 'Rc' defined by its pixel array read-out order. The origin is set to the first pixel being read out, the X-axis points along the column read-out direction towards the last columns, and the Y-axis along the row read-out direction towards the last row. A typical example for a sensor with a 2592x1944 pixel array matrix observed from the front is 2591 X-axis 0 <------------------------+ 0 .......... ... ..........! .......... ... ..........! Y-axis ... ! .......... ... ..........! .......... ... ..........! 1943 V The external world scene reference system 'Rs' is a 2-dimensional reference system on the focal plane of the camera module. The origin is placed on the top-left corner of the visible scene, the X-axis points towards the right, and the Y-axis points towards the bottom of the scene. The top, bottom, left and right directions are intentionally not defined and depend on the environment in which the camera is used. A typical example of a (very common) picture of a shark swimming from left to right, as seen from the camera, is 0 X-axis 0 +-------------------------------------> ! ! ! ! |\____)\___ ! ) _____ __`< ! |/ )/ ! ! !

When projected on the sensor's pixel array, the image and the associated reference system 'Rs' are typically (but not always) inverted, due to the camera module's lens optical inversion effect. Assuming the above represented scene of the swimming shark, the lens inversion projects the scene and its reference system onto the sensor pixel array, seen from the front of the camera sensor, as follow Y-axis ^ ! ! ! ! |\_____)\__ ! ) ____ ___.< ! |/ )/ ! ! ! 0 +-------------------------------------> 0 X-axis Note the shark being upside-down. The resulting projected reference system is named 'Rp'. The camera rotation property is then defined as the angular difference in the counter-clockwise direction between the camera reference system 'Rc' and the projected scene reference system 'Rp'. It is expressed in degrees as a number in the range [0, 360[.
