Claim 0:
1. An automatic payment system comprising:
first and second conveyer stages arranged along a conveying route on which products are moved;
a slope disposed between the first and second conveyer stages on the conveying route;
at least one first ID sensor facing the first conveyer stage to sense IDs attached to the products when the products overlap the first conveyer stage;
at least one second ID sensor facing the second conveyer stage to sense IDs attached to the products when the products overlap the second conveyer stage;
a bottom ID sensor facing the conveyer route under the slope;
at least one camera configured to provide an image by taking a picture of at least a portion of the conveying route and a sales stand on which the products are displayed; and
a controller configured to control the at least one first ID sensor, the at least one second ID sensor, the bottom ID sensor, and the at least one camera, and generate payment information for the products based on at least one of the detection signals received from the at least one first ID sensor, the at least one second ID sensor, the bottom ID sensor, and the at least one camera,
wherein the controller is configured to allow:
a first image captured at a first frame rate to be received by the at least one camera;
a human object to be detected from the first image;
an event signal to be generated when it is detected that the products are picked up by the human object from the first image;
a second image including the human object to be acquired by controlling the at least one camera to capture the image at a second frame rate higher than the first frame rate in response to the event signal; and
the payment information and the second image to be stored in a database.
