Abstract
All light-emitting devices 71 to 73 are caused to emit lights, and the colored lights by light-emitting devices 71 to 73 are radiated to two-dimensional barcode 10 to read barcode information only of a black pattern by CMOS imager 20. Information corresponding to this barcode information is displayed on display section 90. When a user selects information by using input section 100 from among all the information, a light-emitting device corresponding to the selection is caused to emit a light, and a reading operation is performed.
Claims4
A barcode reading apparatus for reading barcode information having a pattern represented in black and multiple patterns represented in colors other than black which are different from one another, the barcode reading apparatus comprising:
- light emission means configured to be able to selectively radiate lights of the colors of the multiple patterns to the barcode information;
- reading means for reading the barcode information in the state during which a light is radiated by the light emission means;
- display means for displaying first information corresponding to the barcode information read by the reading means;
- input means to which second information selected by the first information displayed by the display means is inputted;
- and
- control means for, when all the lights of the colors of the multiple patterns are radiated to the barcode information by the light emission means, and the second information selected by the first information corresponding to barcode information of only the black pattern is inputted to the input means, radiating a light of the color corresponding to the second information to the barcode information by the light emission means.
A barcode reading method for reading barcode information having a pattern represented in black and multiple patterns represented in colors other than black which are different from one another, the barcode reading method comprising:
- radiating all the colors of the multiple patterns to the barcode information;
- reading barcode information of the black pattern in the state during which the lights are radiated;
- displaying first information corresponding to the read barcode information;
- and
- when second information is selected from the first information, radiating a light of the color corresponding to the second information to the barcode information.
