Abstract: 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. The camera captures frames of image data at a first rate, and the near-infrared light emitter is pulsed on/off at a second rate. The first rate is greater than 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, and 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, and the captured second frames of image data are processed at the ECU for a second vehicle function.

Abstract: Examples of the disclosure relate to at least apparatus, methods, and computer programs, configured to control capture of two images of an area, across which a pulse propagates, using different shutter scanning directions. Either the images are converted into pulse-phase maps of the area and a pulse-phase difference map obtained which identifies differences between the pulse-phase maps of the area, or a colour difference map is obtained which identifies differences between the two images and the colour difference map is converted into a pulse-phase difference map. A shutter-time difference map is obtained which identifies differences between capture times of corresponding locations in the two images. Using the shutter-time difference map, the pulse-phase difference map is corrected to obtain a map of pulse-phase changes which have occurred over a duration of a shutter scan.
