A vehicle imaging system includes an imaging device that images at least a part of an area around a vehicle; and a visible light attenuation device that attenuates part of visible light that enters the imaging device. The imaging device includes an imaging element that converts both of the infrared light and an infrared ray to electric signals. The imaging device outputs both of image data produced based on the electric signal to which the visible light, which has entered the imaging device without passing through the visible light attenuation device, has been converted, and image data produced based on the electric signal to which the infrared ray, which has passed through the visible light attenuation device, has been converted.

1. A vehicle imaging system comprising: an imaging device that images at least a part of an area around a vehicle through a front windshield;a head light assembly including:a low beam head lamp which emits a visible light to a region ahead of the vehicle, andan infrared ray projection device that projects an infrared ray to a region ahead of the vehicle, the region to which the infrared ray is projected by the infrared ray projection device being farther from the vehicle than the region to which the visible light is emitted by the low beam head lamp; anda visible light attenuation device which is directly joined to the front windshield, andwhich attenuates part of visible light that enters the imaging device, wherein:the imaging device includes an imaging element that converts both of the visible light and the infrared ray to electric signals, the imaging device outputs both of image data produced based on the electric signal to which the visible light, which has entered the imaging device without passing through the visible light attenuation device, has been converted, and image data produced based on the electric signal to which the infrared ray, which has passed through the visible light attenuation device, has been converted, andwherein the visible light attenuation device, which is directly joined to the front windshield and attenuates part of the visible light that enters the imaging element, is disposed such that the infrared ray, which is projected by a high beam head lamp including the infrared ray projection device and is received by the imaging element, passes through the visible light attenuation device, andwherein the infrared ray projection device is positioned closer to a front end of the vehicle than the front windshield and the imaging device. 2. The vehicle imaging system according to claim 1, wherein: the imaging device images an area ahead of the vehicle through the front windshield. 3. The vehicle imaging system according to claim 2, wherein: the visible light attenuation device is disposed to attenuate the visible light that enters the imaging device from the region to which the infrared ray is projected by the infrared ray projection device. 4. The vehicle imaging system according to claim 3, wherein the infrared ray projection device is a high beam head lamp that is composed of a halogen lamp. 5. The vehicle imaging system according to claim 4, further comprising: a movable filter that is disposed ahead of the infrared ray projection device in a direction in which the infrared ray is projected, and that blocks or attenuate the visible light; anda drive device that changes a position of the movable filter between a position at which the movable filter covers a front surface of the infrared ray projection device, and a position at which the movable filter is removed from the front surface of the infrared ray projection device. 6. The vehicle imaging system according to claim 1, wherein the visible light attenuation device is disposed between the imaging element and an imaging lens that are provided in the imaging device. 7. A vehicle control apparatus comprising: the vehicle imaging system according to claim 1;a collision prediction control device that executes a collision prediction control based on the image data that is produced based on the electric signal to which the infrared ray has been converted, and that is output from the imaging device of the vehicle imaging system; anda lane keeping control device that executes a lane keeping control based on the image data produced based on the electric signal to which the visible light has been converted. 8. The vehicle imaging system according to claim 1, wherein the visible light attenuation device is directly joined to the front windshield by being directly affixed on, inserted into, or integrally formed with the front windshield.
