1. An information processing method performed by a computer of a first system and comprising:
acquiring a first captured image including a pre-passage side area with respect to a first gate at a first lane, a part of the pre-passage side area with respect to a second gate at a second lane adjacent to the first lane on one side, and a part of the pre-passage area with respect to a third gate at a third lane adjacent to the first lane on another side, wherein people move through the first lane to advance to the first gate, through the second lane to advance to the second gate, and through the second lane to advance to the third gate;
when a person is in the first captured image, acquiring a second captured image of the pre-passage side area with respect to the second gate or a third captured image of the pre-passage side area with respect to the third gate with respect to the third gate, based on whether the person based on whether the first person is located in the first image closer to the part of the passage area with respect to the second gate or closer to the part of the passage area with respect to the third gate of another gate; and
recognizing whether the person in the first captured image is advancing toward the first gate based on a comparison of the first captured image and the acquired second or third captured image.
