An improved vision-based system generates object detection corresponding to different viewing areas based on vehicle speed. At lower vehicle speeds, the system covers a wider field of view and a near zone while at higher vehicle speeds the system covers a normal or narrower field of view and a far zone. The system includes a lens package having a movable lens, an image sensor and an image transformer. The movable lens is movable between a first position representing a wide angle view and a second position representing a normal angle view. Each of these views generates an image such that a wide angle view generates a wide angle image and a normal angle view generates a normal angle image. The wide angle view is associated with the vehicle's passive safety systems while the normal angle view is associated with the vehicle's active safety systems.
