Article reading device

Abstract

An article reading device according to an embodiment includes a display device and an image capturing device that generates an image of an article. A processor extracts, from the image, first feature data for recognizing the article and second feature data for determining whether to recognize the article based on the first feature data. The processor determines whether to recognize the article. If it is determined to recognize the article, the processor recognizes the article based on the extracted first feature data, and controls the display device to display a recognition result. If it is determined to not recognize the article, extract a barcode from the image, the processor identifies the article based on the extracted barcode, and control the display device to display an identification result. The processor performs a transaction settlement with respect to the recognition result, if any, and the identification result, if any.

What is claimed is: 
     
         1 . An article reading device for registering an article for purchase, the article reading device comprising:
 a display device;   an image capturing device configured to continuously capture images of an object within an imaging range; and   a processor configured to:
 perform first object recognition on one or more first images captured by the capturing device and attempt to read a code symbol from the first images, 
 when a code symbol is read from the first images,
 acquire article information of an article corresponding to the code symbol, and 
 control the display device to display a first screen showing a button for selecting the article for registration using the article information, and 
 
 when a code symbol is not read from the first images, perform second object recognition on one or more second images captured by the capturing device to identify an article for registration and control the display device to display a second screen showing the second images. 
   
     
     
         2 . The article reading device according to  claim 1 , wherein
 the first screen further shows the first images.   
     
     
         3 . The article reading device according to  claim 1 , wherein
 the second images are enlarged in the second screen.   
     
     
         4 . The article reading device according to  claim 1 , wherein
 the processor is further configured to, when performing the second object recognition, determine one or more candidate articles, and   the candidate articles are also displayed in the second screen.   
     
     
         5 . The article reading device according to  claim 4 , wherein
 one of the candidate articles is selectable for registration through the second screen.   
     
     
         6 . The article reading device according to  claim 4 , further comprising:
 a network interface, wherein   the processor is configured to control the network interface to transmit a result of the second object recognition to a point-of-sale (POS) terminal.   
     
     
         7 . The article reading device according to  claim 4 , wherein
 the processor is further configured to, when no candidate article is determined, control the display device to display a third screen indicating a button to retry the second object recognition.   
     
     
         8 . The article reading device according to  claim 1 , wherein
 the processor is further configured to, before performing the first object recognition, control the display device to display a preset screen showing a plurality of buttons for selecting an article for registration.   
     
     
         9 . The article reading device according to  claim 8 , wherein
 the processor is configured to control the display device to display the first screen in place of the preset screen when the code symbol is read.   
     
     
         10 . The article reading device according to  claim 9 , wherein
 the processor is configured to control the display device to display the preset screen after the button in the first screen is selected.   
     
     
         11 . A method performed by an article reading device for registering an article for purchase, the method comprising:
 performing first object recognition on one or more first images of an object captured by a capturing device and attempting to read a code symbol from the first images,   when a code symbol is read from the first images,
 acquiring article information of an article corresponding to the code symbol, and 
 displaying a first screen showing a button for selecting the article for registration using the article information, and 
   when a code symbol is not read from the first images, performing second object recognition on one or more second images captured by the capturing device to identify an article for registration and displaying a second screen showing the second images.   
     
     
         12 . The method according to  claim 11 , wherein
 the first screen further shows the first images.   
     
     
         13 . The method according to  claim 11 , wherein
 the second images are enlarged in the second screen.   
     
     
         14 . The method according to  claim 11 , wherein
 performing the second object recognition includes determining one or more candidate articles, and   the candidate articles are also displayed in the second screen.   
     
     
         15 . The method according to  claim 14 , wherein
 one of the candidate articles is selectable for registration through the second screen.   
     
     
         16 . The method according to  claim 14 , further comprising:
 transmitting a result of the second object recognition to a point-of-sale (POS) terminal.   
     
     
         17 . The method according to  claim 14 , further comprising:
 when no candidate article is determined, displaying a third screen indicating a button to retry the second object recognition.   
     
     
         18 . The method according to  claim 11 , further comprising:
 before performing the first object recognition, displaying a preset screen showing a plurality of buttons for selecting an article for registration.   
     
     
         19 . The method according to  claim 18 , wherein
 the first screen is displayed in place of the preset screen when the code symbol is read.   
     
     
         20 . The method according to  claim 19 , wherein
 the preset screen is displayed in place of the first screen after the button in the first screen is selected.
