Abstract
A light distribution controlling device determines a light distribution pattern having a dimmed portion to overlap a dimming target present in a region ahead of a vehicle. The light distribution controlling device performs, by using a structuring element of a predetermined shape, a dilation process on a luminous point included in an image capturing the region ahead to generate a dilated region, and determines the dimmed portion based on the dilated region. The light distribution controlling device varies at least one of a size of the structuring element or a position of a pixel of interest in the structuring element in accordance with at least one of a vehicle speed or a rate of turn of the vehicle.
