A method for displaying video images includes providing a plurality of cameras and an ECU at the vehicle. The cameras are in communication with one another via a vehicle network and the ECU is in communication with the cameras via respective data lines. During a driving maneuver of the vehicle, one of the cameras is designated as and functions as a master camera and other cameras are designated as and function as slave cameras. During the driving maneuver, automatic control of exposure, gain and white balance parameters of the designated master camera is enabled, and the exposure, gain and white balance parameters of the designated master camera are communicated to the designated slave cameras via the vehicle network. A composite image is displayed that provides bird's eye view video images derived from video image data captured by at least the designated master camera and the designated slave cameras.
