Patent US 9,509,962

A vision system for a vehicle includes at least one camera disposed at a vehicle so as to have a field of view exterior of the vehicle. Control circuitry includes an image processor for processing image data captured by the camera. The image processor processes image data captured by the camera for a pedestrian detection system of the vehicle. The control circuitry, responsive at least in part to image processing of captured image data by the image processor, is operable to cause adjustment of the pedestrian detection system of the vehicle from regular sensitivity to higher sensitivity. Adjustment from regular sensitivity to higher sensitivity is at least in part responsive to image processing of captured image data by the image processor determining that the vehicle is in the vicinity of children that a driver of the vehicle should watch out for.
