Abstract

A vehicular vision system includes a side-mounted camera disposed at a side of the vehicle. Responsive to (a) actuation of a user input by a driver of the vehicle and/or (b) traveling speed of the vehicle, the vehicular vision system adjusts the side-mounted camera between (i) capturing image data representative of a ground region at the side of the vehicle and (ii) capturing image data representative of regions further away from the vehicle. With the side-mounted camera adjusted to capture image data representative of the ground region at the side of the vehicle, the vehicular vision system may use captured image data for displaying video images at a display device viewable by the driver of the vehicle. With the side-mounted camera adjusted to capture image data representative of regions further away from the vehicle, the vehicular vision system processes captured image data for a driver assistance system of the vehicle.
