A vehicle headlamp system comprising: a camera which is adapted to capture images of a space in front of the vehicle; an image processing part detecting a position of a forward vehicle on the basis of the images captured by the camera; a first lamp unit (14, 20-24) including at least a first light-emitting element and a scanning element that scans light emitted from the first light-emitting element; a second lamp unit (16, 30-32) including at least a plurality of arranged second light-emitting elements and a lens that projects the light emitted from each of the second light-emitting elements; and control means (12, 13, 15) for controlling the operation of the first and second lamp units (14, 16); wherein: the first lamp unit is adapted to perform selective light irradiation in a first region that overlaps with a center area in front of the vehicle in accordance with a position of the forward vehicle by the control of the control means (12, 13); and the second lamp unit is adapted to perform selective light irradiation in a second region that includes at least each region (a21, a22) disposed on a left side and a right side of the first region, in accordance with a position of the forward vehicle by the control of the control means (12, 15); the first region is left-right asymmetrically set across the center area in front of the vehicle. the first lamp unit is adapted to perform a higher definition and selective light irradiation than the second lamp unit; the width of the first region is variably set at least based on road type information acquired from a car navigation system or based on road surface conditions detected by the image processing part where the conditions are assessed by the control part (12, 13, 15) in accordance with the detection result. a camera which is adapted to capture images of a space in front of the vehicle; an image processing part detecting a position of a forward vehicle on the basis of the images captured by the camera; a first lamp unit (14, 20-24) including at least a first light-emitting element and a scanning element that scans light emitted from the first light-emitting element; a second lamp unit (16, 30-32) including at least a plurality of arranged second light-emitting elements and a lens that projects the light emitted from each of the second light-emitting elements; and control means (12, 13, 15) for controlling the operation of the first and second lamp units (14, 16); wherein: the first lamp unit is adapted to perform selective light irradiation in a first region that overlaps with a center area in front of the vehicle in accordance with a position of the forward vehicle by the control of the control means (12, 13); and the second lamp unit is adapted to perform selective light irradiation in a second region that includes at least each region (a21, a22) disposed on a left side and a right side of the first region, in accordance with a position of the forward vehicle by the control of the control means (12, 15); the first region is left-right asymmetrically set across the center area in front of the vehicle. the first lamp unit is adapted to perform a higher definition and selective light irradiation than the second lamp unit; the width of the first region is variably set at least based on road type information acquired from a car navigation system or based on road surface conditions detected by the image processing part where the conditions are assessed by the control part (12, 13, 15) in accordance with the detection result. the first lamp unit is adapted to perform selective light irradiation in a first region that overlaps with a center area in front of the vehicle in accordance with a position of the forward vehicle by the control of the control means (12, 13); and the second lamp unit is adapted to perform selective light irradiation in a second region that includes at least each region (a21, a22) disposed on a left side and a right side of the first region, in accordance with a position of the forward vehicle by the control of the control means (12, 15); the first region is left-right asymmetrically set across the center area in front of the vehicle. the first lamp unit is adapted to perform a higher definition and selective light irradiation than the second lamp unit; the width of the first region is variably set at least based on road type information acquired from a car navigation system or based on road surface conditions detected by the image processing part where the conditions are assessed by the control part (12, 13, 15) in accordance with the detection result.
