Vehicular vision system

A vehicular vision system, the vehicular vision system comprising:

• a global shutter camera disposed at a vehicle equipped with the vehicular vision system;
• wherein the global shutter camera comprises a CMOS imaging array having at least one million photosensor elements arranged in rows and columns;
• wherein the global shutter camera is operable to capture image data;
• a plurality of light emitting diodes operable to emit light;
• an electronic control unit (ECU);
• wherein image data captured by the global shutter camera is transferred to the ECU;
• wherein the ECU comprises an image processor that is operable to process image data captured by the global shutter camera and transferred to the ECU;
• wherein, with the vehicular vision system operating in a floodlight mode, the plurality of light emitting diodes operates to emit light to illuminate a region exterior of the vehicle;
• wherein, with the vehicular vision system operating in a reduced illumination mode, a reduced number of light emitting diodes operates to emit light to illuminate a sub-region of the region that is illuminated when the vehicular vision system is operating in the floodlight mode;
• wherein the reduced number of light emitting diodes is less than all the light emitting diodes of the plurality of light emitting diodes, and wherein the sub-region that is illuminated when the vehicular vision system is operating in the reduced illumination mode is smaller than the region exterior of the vehicle that is illuminated when the vehicular vision system is operating in the floodlight mode;
• wherein at least a portion of the sub-region that is illuminated when the vehicular vision system is operating in the reduced illumination mode is viewed by the global shutter camera;
• wherein the global shutter camera captures image data at a frame-capture rate that is synchronized with a first pulse rate of the reduced number of light emitting diodes when the vehicular vision system is operating in the reduced illumination mode;
• wherein, with the vehicular vision system operating in the reduced illumination mode, image data captured by the global shutter camera is processed at the ECU for a first vehicle function;
• wherein the frame-capture rate of the global shutter camera is synchronized with a second pulse rate of the plurality of light emitting diodes when the vehicular vision system is operating in the floodlight mode;
• and
• wherein, with the vehicular vision system operating in the floodlight mode, image data captured by the global shutter camera is processed at the ECU for a second vehicle function.
