A light distribution control device (6) is provided with: a vehicle detection unit (14) that detects a preceding vehicle by analyzing an image obtained from an imaging device (4) that captures an image of a region ahead of the vehicle; a region determination unit (16) that determines a processing target region in which a predetermined margin is added in the vehicle width direction to the presence region of the preceding vehicle; and a pattern determination unit (18) that, in parallel with the detection of the preceding vehicle by the vehicle detection unit (14), determines a light-blocking section in an image obtained from the imaging device (4) on the basis of pixel values of pairs of light spots arranged in the vehicle width direction included in the processing target region, and determines a light distribution pattern (PTN) including the light-blocking section.
配光控制装置(6)包括:通过从拍摄车辆的前方区域的拍摄装置(4)得到的图像的图像解析来检测前方车辆的车辆检测部(14);确定对前方车辆的存在区域在车宽方向上加上规定的余量的处理对象区域的区域决定部(16);以及,与车辆检测部(14)的前方车辆的检测并行,在从拍摄装置(4)得到的图像中,基于处理对象区域中包含的在车宽方向上排列的光点的对的像素值来确定遮光部,并决定包含遮光部的配光图案(PTN)的图案决定部(18)。
