Label issuing device and label issuing method

1. A label issuing device comprising:

an imaging portion;

an image output portion that outputs an image captured by the imaging portion;

an object recognition portion that recognizes a specific object by reading a feature amount of the output images;

an information reading portion that reads information related to the recognized object from a file storing the information related to the recognized object;

a label issuing portion that prints the read information related to the object on a label and issues the label;

a normal/defective product determination portion that compares a similarity between the output image and a predetermined reference image with a predetermined threshold to determine that the object is not a normal product when the similarity does not exceed the threshold; and

a defective product notification portion that sends a notification indicating that the object is not a normal product when the normal/defective product determination portion determines that the object is not a normal product.

2. The device according to claim 1 , further comprising a notification portion that sends a notification of the read information related to the object.

3. The device according to claim 1 , wherein the similarity is calculated according to a surface state of the object as the feature amount of the images.

4. The device according to claim 1 , wherein the label issuing portion prints price cut information for the object which is not normal product on a label and issues the label, when the notification indicating that the object is not a normal product is sent by the defective product notification portion.

5. The device according to claim 1 , wherein the label issuing portion prints price cut information for the object which is not a normal product on a label and issues the label, when there is an instruction for a price cut sale after the notification indicating that the object is not a normal product is sent by the defective product notification portion.

6. The device according to claim 5 , wherein the threshold includes a plurality of thresholds, and the price cut information for the object includes a plurality of price cut information pieces for the object which are set in stages corresponding to the plurality of thresholds.

7. The device according to claim 1 , wherein the label issuing portion stops printing the information related to the object which is not a normal product on a label and issuing the label, when the notification indicating that the object is not a normal product is sent by the defective product notification portion.

8. The device according to claim 1 , wherein the label issuing portion stops printing the information related to the object which is not a normal product on a label and issuing the label, when there is an instruction for stopping a sale after the notification indicating that the object is not a normal product is sent by the defective product notification portion.

9. A label issuing method comprising:

outputting an image captured by an imaging portion;

recognizing a specific object by reading a feature amount of the output images;

reading information related to the recognized object from a file storing the information related to the recognized object;

printing the read information related to the object on a label and issuing the label;

comparing a similarity between the output image and a predetermined reference image with a predetermined threshold to determine that the object is not a normal product when the similarity does not exceed the threshold; and

sending a notification indicating that the object is not a normal product when the object is determined not to be a normal product.

10. The method according to claim 9 , further comprising sending a notification of the read information related to the object.

11. The method according to claim 9 , wherein similarity is calculated according to a surface state of the object as the feature amount of the images.
