A vehicular vision system, said vehicular vision system comprising: a camera disposed at a vehicle and having a field of view rearward of the vehicle; a light source disposed at the vehicle and operable to emit light, wherein light emitted by said light source, when operated, illuminates at least a portion of the field of view of said camera; wherein said light source comprises a plurality of light segments, and wherein light emitted by each light segment of said light source, when operated, illuminates a respective portion of the field of view of said camera; a control comprising an image processor, wherein image data captured by said camera is provided to said control for processing by said image processor; and wherein said control, responsive to image processing by said image processor of image data captured by said camera, controls intensity of the light emitted by each light segment to provide enhanced object detection via processing at said control of image data captured by said camera, wherein said control independently controls intensity of the light emitted by each light segment of said light source during a reversing maneuver of the vehicle, wherein the reversing maneuver comprises a parking maneuver, characterized in that responsive to detection, via image processing by said image processor of captured image data, of non-optimal illumination of a parking space marker in a portion of the field of view of said camera, said control controls intensity of light emitted by the respective light segment of said light source to enhance illumination of the parking space marker to provide enhanced detection of the parking space marker during the parking maneuver. a camera disposed at a vehicle and having a field of view rearward of the vehicle; a light source disposed at the vehicle and operable to emit light, wherein light emitted by said light source, when operated, illuminates at least a portion of the field of view of said camera; wherein said light source comprises a plurality of light segments, and wherein light emitted by each light segment of said light source, when operated, illuminates a respective portion of the field of view of said camera; a control comprising an image processor, wherein image data captured by said camera is provided to said control for processing by said image processor; and wherein said control, responsive to image processing by said image processor of image data captured by said camera, controls intensity of the light emitted by each light segment to provide enhanced object detection via processing at said control of image data captured by said camera, wherein said control independently controls intensity of the light emitted by each light segment of said light source during a reversing maneuver of the vehicle, wherein the reversing maneuver comprises a parking maneuver, characterized in that responsive to detection, via image processing by said image processor of captured image data, of non-optimal illumination of a parking space marker in a portion of the field of view of said camera, said control controls intensity of light emitted by the respective light segment of said light source to enhance illumination of the parking space marker to provide enhanced detection of the parking space marker during the parking maneuver.
