A device and method for vehicle collision avoidance and mitigation employing a video camera providing a frontal view of a roadway to a video display. A plurality of generally trapezoidal windows formed in front of and rearward of an iconic vehicle are employed to ascertain objects in front of and rearward of the vehicle. Using software, a closing rate of any object is continually calculated, and warnings or evasive actions are taken if a collision is calculated. The device can differentiate between shadows and objects through a filtering method requiring pixel changes in two or more windows concurrently for an object to be determined.
