A camera arrangement for detecting an object such as a driver or a child seat located on, above or in front of a vehicle seat includes a camera (1) for creating an image of any object in that position, and also includes an electromagnetic wave source such as an infrared light source (2). Preferably an image created with the source (2) operational is stored in a first store and an image created with the source (2) non-operational is stored in a second store. The stored images are then subtracted and any object in the subtraction image is identified by an image processor. The position of the object may also be determined and used to inhibit or modify the operation of a safety device such as an airbag in the vehicle. |
