A method of assisting a driver of a vehicle with visualization of an ambient environment comprises generating a mirror image signal corresponding to a field of view of a traditional driving mirror. A surround image signal corresponding to a field of view of an ambient environment adjacent the vehicle is generated. A vehicle speed signal is generated. The mirror image signal, the surround image signal, and the vehicle speed signal are received, and at least one of a driver mirror signal and a driver surround signal is responsively produced. A video image corresponding to at least one of the driver mirror signal and the driver surround signal is selectively displayed to the driver. A frame rate of at least one of the mirror image signal and the surround image signal is adjusted by the signal processor responsive to the vehicle speed signal. A drive assist system is also provided.
