An imaging system for a vehicle includes an imaging device having a forward field of view exterior of the vehicle. The imaging device is operable to capture multiple frames of image data, and the multiple frames of image data include repeating frame sets. A particular frame set of the repeating frame sets has at least two frames. An image processor operable to process image data captured by the imaging device. A control, responsive to processing of captured image data, controls, at least in part, an intelligent headlamp control feature of the vehicle and a lane departure warning feature of the vehicle. One frame of a particular frame set is processed by the image processor for the intelligent headlamp control feature and no other frame of the particular frame set is processed by the image processor for the intelligent headlamp control feature.
