<p>An image capture system for a motor vehicle comprises an electronic control unit (3) which controls the operation of five image capture devices (4) and receives differential signals from the image capture devices (4) representative of digital image data. The electronic control unit (3) processes image data received from the image capture devices (4) and produces a processed image which is displayed on a visual display unit (2) on the dashboard of the motor vehicle. Each image capture device (4) is electrically coupled to the electronic control unit (3) through a separate shielded cable (5) which comprises a pair of first wires (10), a second wire (12) and a third wire (15) mutually electrically insulated from each other. An electrically conductive shield (17) extends around and along the first, second and third wires (10,12,15). The first wires (1,0) carry the differential signal representative of the digital image data. Digital control signals are carried on the second wire (12) between the electronic control unit (3) and the image capture device (4) for controlling the operation of the image capture device (4). The third wire (15) provides a power supply to the image capture device (4) from the electronic control unit (3). The shield (18) of each cable (5) acts as a common ground for the differential signal on the first wires (10), for the digital control signals on the second wire (12) and for the power supply on the third wire (15).</p> |
