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 pixel movement determined closing rate of any object is continually calculated. Thereafter 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. Speed of the vehicles and trajectory can be calculated ahead in virtual depictions to predict a collision and take evasive action.
