Bundling night vision and other driver assistance systems (DAS) using near infra red (NIR) illumination and a rolling shutter

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 by scanning during a frame period and to read the image data into a plurality of image frames, wherein the processor includes a plurality of driver assistance modules configured to perform respectively a plurality of driver assistance functions;
• wherein said camera is configured to provide to the processor said image frames, wherein the image frames are partitioned into first image frames for use by a first driver assistance module and into second image frames for use by a second driver assistance module;
• 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;
• wherein the first driver assistance module is configured to use the near infra-red illumination in a part of an image in at least one of the first image frames, wherein the second driver assistance module is configured to use a part of an image in at least one of the second image frames that does not have said near infrared illumination;
• a synchronization mechanism configured to synchronize said illumination period to said frame period of said rolling shutter to time said near infra-red illumination to be in said part of the image of said at least one of the first image frames and to avoid said near infra-red illumination in said part of the image of said at least one of the second image frames.
