Abstract
A data determination apparatus includes: a memory; and a processor coupled to the memory. The processor is configured to: calculate a difference in signal values between each combination of neighboring pixels among a plurality of pixels forming image data of a barcode; compare a sum of a plurality of the differences with a reference value; and detect, based on a result of the comparing, a pixel at a boundary position at which a signal value of the pixel is switched from one of a first value and a second value to a remaining one of the first value and the second value among the plurality of pixels forming the image data.
Claims18
A data determination apparatus comprising:
- a memory;
- and
- a processor coupled to the memory, the processor being configured to:
- calculate a difference in signal values between each combination of neighboring pixels among a plurality of pixels forming image data of a barcode;
- compare a sum of a plurality of the differences with a reference value;
- and
- detect, based on a result of the comparing, a pixel at a boundary position at which a signal value of the pixel is switched from one of a first value and a second value to a remaining one of the first value and the second value among the plurality of pixels forming the image data.
A library apparatus configured to store a plurality of recording media each displaying a barcode, the library apparatus comprising a reading apparatus configured to read a barcode of a recording medium in response to a reading instruction for a barcode, the reading apparatus comprising:
- a memory;
- and
- a processor coupled to the memory, the processor being configured to:
- calculate a difference in signal values between each combination of neighboring pixels among a plurality of pixels forming image data of a barcode;
- compare a sum of a plurality of the differences with a reference value;
- and
- detect, based on a result of the comparing, a pixel at a boundary position at which a signal value of the pixel is switched from one of a first value and a second value to a remaining one of the first value and the second value among the plurality of pixels forming the image data.
A non-transitory computer-readable recording medium having stored therein a data determining program for causing a computer to execute a process comprising:
- calculating a difference in signal values between each combination of neighboring pixels among a plurality of pixels forming image data of a barcode;
- comparing a sum of a plurality of the differences with a reference value;
- and
- detecting, based on a result of the comparing, a pixel at a boundary position at which a signal value of the pixel is switched from one of a first value and a second value to a remaining one of the first value and the second value among the plurality of pixels forming the image data.
