## Abstract

A store exit management system according to an aspect of the present disclosure includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: acquire a payment completion code from a portable terminal operated by a customer when a product was registered and paid for through the portable terminal; acquire a quantity of a payment completion product associated with the payment completion code; estimate, from an image obtained by imaging goods of the customer leaving a store, a quantity of a product to be taken out by the customer; detect an abnormality based on the acquired quantity of the payment completion product and the estimated quantity of the product to be taken out; and output information indicating that the abnormality is detected.

## Claims

### Claim 1

A store exit management system comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
acquire a payment completion code from a portable terminal operated by a customer when a product was registered and paid for through the portable terminal;
acquire a quantity of a payment completion product associated with the payment completion code;
estimate, from an image obtained by imaging goods of the customer leaving a store, a quantity of a product to be taken out by the customer;
detect an abnormality based on the acquired quantity of the payment completion product and the estimated quantity of the product to be taken out; and
output information indicating that the abnormality is detected.

### Claim 2 (depends on 1)

The store exit management system according to claim 1, wherein the at least one processor is further configured to execute the instructions to:
detect the abnormality based on a difference between the estimated quantity of the product to be taken out and the quantity of the payment completion product.

### Claim 3 (depends on 2)

The store exit management system according to claim 2, wherein the at least one processor is further configured to execute the instructions to:
detect the abnormality in a case where a difference between the estimated quantity of the product to be taken out and the quantity of the payment completion product exceeds a threshold value.

### Claim 4 (depends on 1)

The store exit management system according to claim 1, wherein the at least one processor is further configured to execute the instructions to:
detect the abnormality in a case where the estimated quantity of the product to be taken out is larger than the quantity of the payment completion product.

### Claim 5 (depends on 1)

The store exit management system according to claim 1, wherein the at least one processor is further configured to execute the instructions to:
detect the abnormality in a case where the estimated quantity of the product to be taken out is smaller than the quantity of the payment completion product.

### Claim 6 (depends on 1)

The store exit management system according to claim 1, wherein
the quantity of the payment completion product is a volume of the payment completion product, and
the quantity of the product to be taken out is a volume of the product to be taken out.

### Claim 7 (depends on 1)

The store exit management system according to claim 1, wherein
the quantity of the payment completion product is the number of the payment completion products, and
the quantity of the product to be taken out is the number of the products to be taken out.

### Claim 8 (depends on 1)

The store exit management system according to claim 1, wherein the at least one processor is further configured to execute the instructions to:
estimate the quantity of the product to be taken out from the image obtained by imaging the goods of the customer leaving the store and an image obtained by imaging goods of the customer before holding the product to be taken out.

### Claim 9 (depends on 1)

The store exit management system according to claim 1, wherein the at least one processor is further configured to execute the instructions to:
control a store exit gate through which the customer leaving the store passes to make the store exit gate impassable in a case where the abnormality is detected.

### Claim 10 (depends on 1)

The store exit management system according to claim 1, wherein the at least one processor is further configured to execute the instructions to:
output the number of the payment completion products to a notification device in response to acquisition of the payment completion code.

### Claim 11

A store exit management method comprising:
acquiring a payment completion code from a portable terminal operated by a customer when a product was registered and paid for through the portable terminal;
acquiring a quantity of a payment completion product associated with the payment completion code;
estimating, from an image obtained by imaging goods of the customer leaving a store, a quantity of a product to be taken out by the customer;
detecting an abnormality based on the acquired quantity of the payment completion product and the estimated quantity of the product to be taken out; and
outputting information indicating that the abnormality is detected.

### Claim 12

A recording medium that non-transiently records a program for causing a computer to execute the steps of:
acquiring a payment completion code from a portable terminal operated by a customer when a product was registered and paid for through the portable terminal;
acquiring a quantity of a payment completion product associated with the payment completion code;
estimating, from an image obtained by imaging goods of the customer leaving a store, a quantity of a product to be taken out by the customer;
