and a determination unit that determines, based on the height information, whether or not the user is a candidate for person requiring assistance, who may be a person requiring assistance. ## Claims ### Claim 1 An information processing apparatus comprising: a memory configured to store instructions; and a processor configured to execute the instructions to: acquire height information relating to a height of a capturing position of an imaging device that captured an image in which a face of a user was detected; determine, based on the height information, whether or not the user is a candidate for person requiring assistance, who may be a person requiring assistance; and perform a matching operation to match the face of the user in the image with a plurality of registered face images registered in database in a 1:N manner. ### Claim 2 (depends on 1) The information processing apparatus according to claim 1, wherein the processor is further configured to execute the instructions to: determine that the user is the candidate for person requiring assistance when the height of the capturing position of the imaging device is a predetermined height or less. ### Claim 3 (depends on 2) The information processing apparatus according to claim 2, wherein the imaging device includes a first imaging device and a second imaging device installed at a higher position than the first imaging device, and wherein the processor is further configured to execute the instructions to: determine that the user is the candidate for person requiring assistance when the image was captured by the first imaging device. ### Claim 4 (depends on 2) The information processing apparatus according to claim 2, wherein the imaging device can move up and down to change the height, and wherein the processor is further configured to execute the instructions to: determine that the user is the candidate for person requiring assistance when the imaging device captured the image at the height equal to or lower than a predetermined height. ### Claim 5 (depends on 1) The information processing apparatus according to claim 1, wherein the processor is further configured to execute the instructions to: notify a notification destination of an alarm indicating that the candidate for person requiring assistance is detected when the user is determined to be the candidate for person requiring assistance. ### Claim 6 (depends on 5) The information processing apparatus according to claim 5, wherein the processor is further configured to execute the instructions to: notify the alarm to the notification destination having a predetermined positional relationship with a position at which the candidate for person requiring assistance is detected. ### Claim 7 (depends on 6) The information processing apparatus according to claim 6, wherein the processor is further configured to execute the instructions to: notify the alarm to the notification destination located within a predetermined distance range from the position at which the candidate for person requiring assistance is detected. ### Claim 8 (depends on 5) The information processing apparatus according to claim 5, wherein the notification destination is an attendant terminal used by an attendant, a signage terminal, or a user terminal used by the user. ### Claim 9 (depends on 5) The information processing apparatus according to claim 5, wherein the processor is further configured to execute the instructions to: stop the alarm upon receiving information indicating that it is being confirmed whether or not the candidate for person requiring assistance is a person requiring assistance. ### Claim 10 (depends on 1) The information processing apparatus according to claim 1, wherein the processor is further configured to execute the instructions to: register information about the user when the user is determined to be the candidate for person requiring assistance. ### Claim 11 (depends on 10) The information processing apparatus according to claim 10, wherein the processor is further configured to execute the instructions to: when receiving information indicating that confirmation of whether or not the candidate for person requiring assistance is a person requiring assistance is completed, delete the information about the user. ### Claim 12 (depends on 1) The information processing apparatus according to claim 1, wherein the processor is further configured to execute the instructions to: issue an identifier associating a registered biometric information of the user with operation information related to a predetermined operation, wherein the operation information includes information indicating whether or not the user is a candidate for person requiring assistance. ### Claim 13 (depends on 1) The information processing apparatus according to claim 1, wherein the candidate for person requiring assistance is a wheelchair user or a child in a predetermined age range. ### Claim 14 An information processing method comprising: acquiring height information relating to a height of a capturing position of an imaging device that captured an image in which a face of a user was detected; determining, based on the height information, whether or not the user is a candidate for person requiring assistance, who may be a person requiring assistance; and performing a matching operation to match the face of the user in the image with a plurality of registered face images registered in database in a 1:N manner. ### Claim 15 A non-transitory storage medium storing a program that causes a computer to perform: acquiring height information relating to a height of a capturing position of an imaging device that captured an image in which a face of a user was detected; determining, based on the height information, whether or not the user is a candidate for person requiring assistance, who may be a person requiring assistance; and performing a matching operation to match the face of the user in the image with a plurality of registered face images registered in database in a 1:N manner.
