Abstract

An image processing apparatus includes an extractor that receives sheet image data that is generated by reading an image on a medical record sheet onto which basic medical information and encoded information of the basic medical information are printed, and extracts, from the sheet image data, information image data representing a portion where the basic medical information is printed, an image generator that generates reference image data representing the basic medical information, based on the encoded information represented in the sheet image data, and a detector that detects a correction that is to be performed on the basic medical information printed on the medical record sheet, based on a difference between the information image data and the reference image data.

Claims

1. An image processing apparatus comprising:

an extractor that receives sheet image data that is generated by reading an image on a medical record sheet onto which basic medical information and encoded information of the basic medical information are printed, and extracts, from the sheet image data, information image data representing a portion where the basic medical information is printed;

an image generator that generates reference image data representing the basic medical information, based on the encoded information represented in the sheet image data; and

a detector that detects a correction that is to be performed on the basic medical information printed on the medical record sheet, based on a difference between the information image data and the reference image data.

2. The image processing apparatus according to claim 1, wherein the image generator comprises:

a decoding unit that generates decoded information by decoding the encoded information; and

an image reproducing unit that reproduces the reference image data from the decoded information in accordance with an expression condition to be used for comparison with the information image data.

3. The image processing apparatus according to claim 2,

wherein the image reproducing unit reproduces the reference image data from the decoded information in accordance with an expression condition similar to an expression condition for the basic medical information printed on the medical record sheet.

4. The image processing apparatus according to claim 2,

wherein the basic medical information comprises a plurality of items,

wherein the extractor extracts the information image data on a per item basis,

wherein the image reproducing unit reproduces the reference image data on a per item basis, and

wherein the detector detects the correction on a per item basis.

5. The image processing apparatus according to claim 3,

wherein the basic medical information comprises a plurality of items,

wherein the extractor extracts the information image data on a per item basis,

wherein the image reproducing unit reproduces the reference image data on a per item basis, and

wherein the detector detects the correction on a per item basis.

6. The image processing apparatus according to claim 2, further comprising an executing unit that executes an operation related to the correction on the decoded information if the detector has detected the correction.

7. The image processing apparatus according to claim 3, further comprising an executing unit that executes an operation related to the correction on the decoded information if the detector has detected the correction.

8. The image processing apparatus according to claim 4, further comprising an executing unit that executes an operation related to the correction on the decoded information if the detector has detected the correction.

9. The image processing apparatus according to claim 5, further comprising an executing unit that executes an operation related to the correction on the decoded information if the detector has detected the correction.

10. The image processing apparatus according to claim 6, wherein the execution unit executes an operation related to the correction of a portion corresponding to a difference between the information image data and the reference image data in the decoded information.

11. The image processing apparatus according to claim 7, wherein the execution unit executes an operation related to the correction of a portion corresponding to a difference between the information image data and the reference image data in the decoded information.

12. The image processing apparatus according to claim 8, wherein the execution unit executes an operation related to the correction of a portion corresponding to a difference between the information image data and the reference image data in the decoded information.

13. The image processing apparatus according to claim 9, wherein the execution unit executes an operation related to the correction of a portion corresponding to a difference between the information image data and the reference image data in the decoded information.

14. The image processing apparatus according to claim 10, wherein the execution unit outputs information indicating a correction candidate to the portion corresponding to the difference.

15. The image processing apparatus according to claim 11, wherein the execution unit outputs information indicating a correction candidate to the portion corresponding to the difference.

16. The image processing apparatus according to claim 14, wherein the execution unit identifies a character to be modified from the portion corresponding to the difference and outputs, as the correction candidate, information indicating the character to be modified.

17. The image processing apparatus according to claim 15, wherein the execution unit identifies a character to be modified from the portion corresponding to the difference and outputs, as the correction candidate, information indicating the character to be modified.

18. The image processing apparatus according to claim 1, further comprising an output unit that outputs a warning if the detector detects the correction.

19. An image processing method comprising,

receiving sheet image data that is generated by reading an image on a medical record sheet onto which basic medical information and encoded information of the basic medical information are printed, and extracting, from the sheet image data, information image data representing a portion where the basic medical information is printed;

generating reference image data representing the basic medical information, based on the encoded information represented in the sheet image data; and

detecting a correction that is to be performed on the basic medical information printed on the medical record sheet, based on a difference between the information image data and the reference image data.

20. A non-transitory computer readable medium storing a program causing a computer to execute a process for processing an image, the process comprising:

receiving sheet image data that is generated by reading an image on a medical record sheet onto which basic medical information and encoded information of the basic medical information are printed, and extracting, from the sheet image data, information image data representing a portion where the basic medical information is printed;

generating reference image data representing the basic medical information, based on the encoded information represented in the sheet image data; and

detecting a correction that is to be performed on the basic medical information printed on the medical record sheet, based a difference between the information image data and the reference image data.
