1. 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 emitters 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 emitters operates to emit light to illuminate a region;
wherein, with the vehicular vision system operating in a reduced illumination mode, a reduced number of light emitters 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 emitters is less than all the light emitters of the plurality of light emitters, 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 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 pulse rate of the reduced number of light emitters when the vehicular vision system is operating in the reduced illumination mode; and
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 vehicle function.
