A lighting device includes a plurality of lighting elements forming a lighting matrix configured to illuminate the field of vision of the optical device. A control device associated with the optical device and the lighting device is configured to determine the nature of each image of an object captured by the optical device. The control device is configured to locate the object, select the lighting elements of the lighting matrix capable of illuminating the object relative to the location of the object, and individually control at least one lighting characteristic of each selected lighting element so as to be able to determine the nature of the image of the object captured by the optical device. ## Claims ### Claim 1 A vision system for a motor vehicle, comprising: an optical device comprising a camera configured to capture images of objects in a field of vision of the optical device; a lighting device including a plurality of lighting elements forming a lighting matrix configured to illuminate the field of vision of the optical device; and a control device associated with the optical device and the lighting device, the control device being configured to determine a nature of an object in an image captured by the camera, the control device being configured to determine a location of the object by analyzing the image captured by the camera, and process the image captured by the camera to identify the nature of the object; wherein when the control device cannot determine the nature of the object by analyzing the image captured by the camera, the control device is configured to select the lighting elements of the lighting matrix capable of illuminating the object based on the determined location of the object, individually control at least one lighting characteristic of each selected lighting element during a temporary time sequence imperceptible by the human eye, and determine the nature of the object by analyzing at least one other image captured by the camera during the temporary time sequence. ### Claim 2 (depends on 1) The system according to claim 1, wherein the control device is configured to adjust the at least one lighting characteristic by adjusting a lighting power of each lighting element of the lighting matrix making it possible to illuminate the object in the at least one other image. ### Claim 3 (depends on 1) The system according to claim 1, wherein the plurality of lighting elements forming a lighting matrix includes a plurality of red-green-blue light-emitting diodes, and the control device is configured to individually adjust a color of the light-emitting diodes of each lighting element of the lighting matrix. ### Claim 4 (depends on 1) The system according to claim 1, comprising a radar or lidar object detection device configured to detect the presence of at least one object in the field of vision of the optical device, the control device being configured to individually adjust the at least one lighting characteristic of each lighting element of the lighting matrix to illuminate the object detected by the object detection device so that the control device can determine the nature the object in a subsequent image captured by the optical device. ### Claim 5 (depends on 1) The system according to claim 1, wherein the vision system is associated with a driver assistance device of the vehicle, the lighting device includes a headlight of the vehicle, the field of vision of the optical device corresponds to a field of vision in front of the vehicle. ### Claim 6 (depends on 1) An object detection method using the vision system of claim 1, the method comprising: detecting an object in the field of vision of the optical device; locating the object subsequent to the detecting by analyzing an image captured by the camera; selecting the lighting elements of the lighting matrix capable of illuminating the object based on the location of the detected object; adjusting the at least one lighting characteristic of the lighting elements illuminating the detected object during a temporary time sequence imperceptible by the human eye; and determining the nature of the object by analyzing the at least one other image captured by the camera during the temporary time sequence. ### Claim 7 (depends on 6) The method according to claim 6, wherein detecting the object in the field of vision of the optical device comprises using a radar or lidar device for detecting objects in the field of vision of the optical device. ### Claim 8 (depends on 6) The method according to claim 6, wherein adjusting the at least one lighting characteristic comprises adjusting a lighting power of each selected lighting element of the lighting matrix. ### Claim 9 (depends on 6) The method according to claim 6, wherein determining the nature of the object comprises identifying a type of the object. ### Claim 10 (depends on 9) The method according to claim 9, wherein identifying the type of the object includes determining whether the object is a pedestrian. ### Claim 11 (depends on 9) The method according to claim 9, wherein identifying the type of the object includes determining whether the object is a bicycle. ### Claim 12 (depends on 1) The vision system according to claim 1, wherein the control device is configured to determine the nature of the object in the image captured by the optical device by identifying a type of the object. ### Claim 13 (depends on 12) The vision system according to claim 12, wherein identifying the type of the object includes determining whether the object is a pedestrian. ### Claim 14 (depends on 12) The vision system of claim 12, wherein identifying the type of the object includes determining whether the object is a bicycle.
