Image processing apparatus and image processing program
An image processing apparatus includes a processor that acquires document image data that is generated by reading an original document and recognizes character strings that are included in the document image data through character recognition, and the processor selects, as an issuing date of the original document, date information that includes time information from among a plurality of date information pieces in a case in which the plurality of date information pieces are extracted from among the character strings. The processor distinguishes a type of the original document on the basis of the document image data and selects date information as an issuing date of the original document from among the plurality of date information pieces in accordance with the type of the original document in a case in which no date information that includes time information has not been extracted.
1. An image processing apparatus comprising:
a processor that
acquires document image data that is generated by reading an original document,
recognizes character strings that are included in the document image data through character recognition,
distinguishes a type of the original document on the basis of the character strings included in the document image data,
selects, as an issuing date of the original document, date information that includes time information from a plurality of date information pieces in a case in which the plurality of date information pieces are extracted from the character strings, and
selects, from the plurality of date information pieces, date information as the issuing date of the original document in accordance with the type of the original document in a case in which no date information that includes the time information has been extracted from the character strings.
2. The image processing apparatus according to claim 1 ,
wherein the processor distinguishes the type of the original document on the basis of a size of the original document indicated by the document image data.
3. The image processing apparatus according to claim 1 ,
wherein the processor selects, with priority, old date information from the plurality of date information pieces in a case in which the type of the original document is a receipt.
4. The image processing apparatus according to claim 1 ,
wherein the processor selects, with priority, new date information from the plurality of date information pieces in a case in which the type of the original document is a receipt of an accommodation facility.
5. The image processing apparatus according to claim 1 ,
wherein the processor does not extract date information that is described along with a character string that limits a period.
6. The image processing apparatus according to claim 1 ,
wherein the processor does not extract date information that is newer than date and time of generation of the document image data.
7. The image processing apparatus according to claim 1 ,
wherein the processor causes a display unit to display a file name that includes the issuing date as a file name of the document image data.
8. A non-transitory computer readable medium storing computer-executable instructions which, when executed by a processor of an image processing apparatus, cause the processor to execute a process, the process comprising:
acquiring document image data that is generated by reading an original document,
executing a control function of recognizing character strings that are included in the document image data through character recognition,
distinguishing a type of the original document on the basis of the character strings included in the document image data,
selecting, as an issuing date of the original document, date information that includes time information from a plurality of date information pieces in a case in which the plurality of date information pieces are extracted from among the character strings, and
selecting, from the plurality of date information pieces, date information as the issuing date of the original document in accordance with the type of the original document in a case in which no date information that includes the time information has been extracted from the character strings.
9. An image processing apparatus comprising:
a processor that
acquires document image data that is generated by reading an original document,
recognizes character strings that are included in the document image data through character recognition,
distinguishes a type of the original document on the basis of a size of the original document indicated by the document image data,
selects, as an issuing date of the original document, date information that includes time information from a plurality of date information pieces in a case in which the plurality of date information pieces are extracted from the character strings, and
selects, from the plurality of date information pieces, date information as the issuing date of the original document in accordance with the type of the original document in a case in which no date information that includes the time information has been extracted from the character strings.
