1. A light distribution control device, comprising:
a storage device storing a program; and
a hardware processor,
wherein the hardware processor, by executing the program stored in the storage device:
acquires information representing a running status of an assistance operation performed for driving assistance from a driving assistance device performing driving assistance of a subject vehicle based on a recognition result of objects disposed in front of the subject vehicle recognized based on detection results acquired by a plurality of sensors including an optical sensor;
performs light distribution control including change of an output level of a headlight of the subject vehicle; and
performs change of the output level of the headlight, in the light distribution control, the change is performed such that there is not an adverse effect on the assistance operation in accordance with running of the assistance operation,
wherein the hardware processor returns the light distribution of the headlight to a state before change in a case in which an image feature quantity relating to recognition of the object has been changed with a degree for which the object is not able to be recognized by changing the output level of the headlight.
