A light distribution controller includes a computation unit that extracts an index value from a predetermined region to be processed within an image, a pattern determiner that determines a light distribution pattern such that the index value approaches a maximum value, and a lamp controller that controls a light distribution variable lamp so as to form the light distribution pattern. The index value is at least one of a mean intensity of HOG feature values of a plurality of pixels of the region to be processed or an edge gray level proportion indicating, in a local binary pattern (LBP) histogram of the plurality of pixels, a proportion of the number of pixels belonging to a gray level of an edge portion to a total number of the plurality of pixels.
