Vehicular headlamp system

[TASK] To suitably detect a light emitting object and a reflective object ahead of a vehicle. [MEANS OF SOLVING THE PROBLEM] A vehicular headlamp system 100 includes: a vehicular headlamp 10 that can independently irradiate each of a plurality of segmented regions that divide a light distribution region forward of an own vehicle; an irradiation control portion 44 that controls the vehicular headlamp 10 so as to repeatedly alternate between irradiating and not irradiating light to each segmented region; a camera 40 that respectively images forward of the own vehicle during irradiation and non-irradiation of the segmented region, and generates an irradiation image and a non-irradiation image; a high-luminance part detection portion 46 that detects a high-luminance part within the irradiation image and the non-irradiation image; and a light emitting object determination portion 48 that distinguishes between and detects a light emitting object and a reflective object present ahead of the vehicle by comparing whether the high-luminance part is present in both images.
