CHECKOUT SYSTEM AND METHOD FOR OPERATING CHECKOUT SYSTEM
First Claim
1. A checkout system, comprising:
- a terminal to register sales of a commodity; and
a commodity reading device including an image pickup part to acquire an image of the commodity; and
a display device;
wherein,the commodity reading device detects the commodity from the acquired image, and computes a similarity coefficient between the detected commodity image and a standard image for each commodity from a list of commodities to determine candidate matches for the commodity from the acquired image and display the candidate matches on the display device.

Abstract
A checkout system of an embodiment of the present disclosure has an image pickup unit, a computing unit, a display control unit, a receiving unit, and a registering unit. The image pickup unit takes pictures of a commodity at a prescribed frame rate. The computing unit computes a similarity coefficient between standard images of each commodity and the acquired image to identify possible matches to the acquired image. The display control unit displays information corresponding to the candidate matches with a high similarity coefficient on a display unit. The similarity coefficient is determined on the basis of a comparison between images of the object acquired by the image pickup unit and a standard image. The receiving unit receives selection of the commodity information on the display unit. The registering unit executes a registration treatment according to the selected information.
