1. A light distribution controlling device, comprising:
a vehicle detector that detects a front vehicle through an image analysis on an image obtained from an imaging device that captures an image of a region ahead of a vehicle;
a region determiner that sets a processing region by adding a predetermined margin in a widthwise direction of the vehicle to a presence region of the front vehicle; and
a pattern determiner that, in parallel with the detection of the front vehicle by the vehicle detector, sets a light blocking portion based on a pixel value of a pair of luminous points included in the processing region and appearing side by side in the widthwise direction of the vehicle in the image obtained from the imaging device and determines a light distribution pattern that includes the light blocking portion, wherein
the pattern determiner
sets, in the image, a left luminous point pixel that overlaps a left luminous point in the pair of luminous points and a predetermined number of upper left pixels that are arrayed in an upward direction from the left luminous point pixel as an upper left dilating group, and sets, in the image, a right luminous point pixel that overlaps a right luminous point and a predetermined number of upper right pixels that are arrayed in the upward direction from the right luminous point pixel as an upper right dilating group,
sets the upper left dilating group and a predetermined number of right column pixels that are arrayed in a right direction from the upper left dilating group as a right dilating group,
sets the upper right dilating group and a predetermined number of left column pixels that are arrayed in a left direction from the upper right dilating group as a left dilating group, and
incorporates a pixel region where the right dilating group and the left dilating group overlap each other into the light blocking portion.
