1. An object recognition system, comprising at least one processor configured to:
input an input image to a learning model for recognizing a first object;
acquire a heat map about a position that is a basis for recognition of the first object by the learning model having the input image input thereto based on a Class Activation Map method;
acquire a motion image about a position of a moving body that is included in the input image based on motion detection processing;
acquire another image by retaining a part of the input image in which a sum of a pixel value in the heat map and a pixel value in the motion image is equal to or more than a threshold value; and
acquire position information about a position of the first object included in the input image, based on the heat map and the motion image.
