Physical rear camerasiOne row per physical imaging camera. Sensor crops, optical-quality zoom modes, autofocus laser and depth scanners do not add photographic lenses. A colour or multispectral sensor is not a camera row, even when the maker gives it a megapixel figure. A depth camera with its own megapixel figure, such as a 2 MP depth camera, is a row with the depth role. A ToF or lidar scanner is not a row.
