Patent attributes
A vehicular vision system includes a camera, a near-infrared light emitter operable to illuminate at least part of a region viewed by the camera, and an electronic control unit having an image processor. While the camera is capturing frames of image data at a first rate, the near-infrared light emitter is pulsed on/off at a second rate. The first rate is at least two times the second rate. First frames of image data are captured by the camera when the region is illuminated by light emitted by the near-infrared light emitter. The captured first frames of image data are processed at the ECU for a first vehicle function. Second frames of image data are captured by the camera when the region is not illuminated by light emitted by the near-infrared light emitter. The captured second frames of image data are processed at the ECU for a second vehicle function.
