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