and at least one processor configured to execute the instructions to: acquire an image generated by a camera; extract a person in the acquired image; select a person who performs a settlement process based on a distance from a checkout apparatus in a case where a plurality of persons are extracted; identify the selected person based on the image in which the person is included, and database information in which a feature value of a face is registered; and perform the settlement process with respect to the identified person, ### Claim 2 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to select a person of which the distance from the checkout apparatus is equal to or less than a reference value. ### Claim 3 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to select a person of which the distance from the checkout apparatus is the smallest. ### Claim 4 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to decide at least one of a person of which a frequency acquired by capturing during a prescribed time frame is high and a person of which a period of time acquired by capturing during a prescribed time frame is long as the person who performs the settlement process in a case where a plurality of persons are selected. ### Claim 5 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to decide a person who performs a prescribed behavior as the person who performs the settlement process in a case where a plurality of persons are selected. ### Claim 6 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to: acquire a voice; and decide a person who makes a prescribed remark as the person who performs the settlement process based on the acquired voice in a case where a plurality of persons are selected. ### Claim 7 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to decide a person of which an estimated age estimated based on the image is equal to or larger than a reference value as the person who performs the settlement process in a case where a plurality of persons are selected. ### Claim 8 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to decide a person who makes movement as the person who performs the settlement process in a case where a plurality of persons are selected. ### Claim 9 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to decide a person of which an estimated age estimated based on the image is equal to or smaller than a reference value as the person who performs the settlement process in a case where a plurality of persons are selected. ### Claim 10 (depends on 1) The information processing system according to claim 1, wherein the processor is further configured to execute the instructions to decide a person who makes no movement as the person who performs the settlement process in a case where a plurality of persons are selected. ### Claim 11 An information processing method, which is performed by a computer, the method comprising: acquiring an image generated by a camera; extracting a person in the acquired image; selecting a person who performs a settlement process based on a distance from a checkout apparatus in a case where a plurality of persons are extracted; identifying the selected person based on the image in which the person is included, and database information in which a feature value of a face is registered; and performing the settlement process with respect to the identified person. ### Claim 12 A non-transitory storage medium storing a program causing a computer to: acquire an image generated by a camera; extracts a person in the acquired image; select a person who performs a settlement process based on a distance from a checkout apparatus in a case where a plurality of persons are extracted; identify the selected person based on the image in which the person is included, and database information in which a feature value of a face is registered; and perform the settlement process with respect to the identified person.
