Vehicular vision system with controlled exterior lighting device and camera

A vehicular vision system, the vehicular vision system comprising:

• an exterior lighting assembly configured for mounting at a vehicle equipped with the vehicular vision system, wherein the exterior lighting assembly, when activated, emits light that illuminates a field of illumination exterior of the equipped vehicle;
• wherein the exterior lighting assembly comprises a plurality of light emitting diodes;
• a light source controller that operates the exterior lighting assembly to emit light in a repeating cycle that includes (i) a first illumination period wherein the exterior lighting assembly is operated to emit light at a first brightness level, and (ii) a second illumination period wherein the exterior lighting assembly is operated to emit light at a second brightness level that is lower than the first brightness level;
• wherein the light source controller operates at least one light emitting diode of the plurality of light emitting diodes of the exterior lighting assembly to emit light in the repeating cycle;
• a camera disposed at the equipped vehicle, wherein the camera captures image data representative of a region that is at least in part within the field of illumination illuminated by the exterior lighting assembly with the exterior lighting assembly mounted at the equipped vehicle and with the exterior lighting assembly operated to emit light;
• a camera controller that controls the camera, wherein, with the exterior lighting assembly mounted at the equipped vehicle and with the exterior lighting assembly operated to emit light, the camera controller operates the camera to capture image data during at least part of the first illumination period and during at least part of the second illumination period;
• a camera signal processor that receives image data captured by the camera during the first illumination period and receives image data captured by the camera during the second illumination period;
• and
• wherein the received image data captured by the camera during the first illumination period is processed at the camera signal processor for display, at a display device disposed in the equipped vehicle, of video images derived from the image data captured by the camera during the first illumination period.
