BUNDLING NIGHT VISION AND OTHER DRIVER ASSISTANCE SYSTEMS (DAS) USING NEAR INFRA RED (NIR) ILLUMINATION AND A ROLLING SHUTTER
First Claim
1. A system mountable in a motor vehicle, the system comprising:
- a camera;
a processor configured to receive image data from the camera;
wherein the camera includes a rolling shutter configured to capture said image data during a frame period and to read the image data into a plurality of image frames;
a near infra-red illuminator configured to provide a near infra-red illumination cone in the field of view of the camera, wherein the near infrared illumination oscillates with an illumination period; and
a synchronization mechanism configured to synchronize said illumination period to said frame period of said rolling shutter.

Abstract
A system mountable in a motor vehicle. The system includes a camera and a processor configured to receive image data from the camera. The camera includes a rolling shutter configured to capture the image data during a frame period and to scan and to read the image data into multiple image frames. A near infra-red illuminator may be configured to provide a near infra-red illumination cone in the field of view of the camera. The near infrared illumination oscillates with an illumination period. A synchronization mechanism may be configured to synchronize the illumination period to the frame period of the rolling shutter. The frame period may be selected so that the synchronization mechanism provides a spatial profile of the near infra-red illumination cone which may be substantially aligned vertically to a specific region, e.g. near the center of the image frame.
