Abstract

An information reading apparatus that reads information from an image. The apparatus includes: an acquiring module, a first processing module, a second processing module, and an adding module. The acquiring module acquires a whole image containing plural reading subjects. The first processing module performs processing of extracting particular patterns from the respective reading subjects by performing a pattern analysis on the whole image to identify the reading subjects contained in the whole image. The second processing module performs processing of reading pieces of information from the respective reading subjects and recognizing the read-out pieces of information by analyzing the respective particular patterns extracted by the first processing module. The adding module adds current processing statuses for the respective reading subjects contained in the whole image based on at least one of sets of processing results of the first processing module and the second processing module.

Claims

1. An information reading apparatus that reads information from an image, the apparatus comprising:

an acquiring module that acquires a whole image containing plural reading subjects;

a first processing module that performs processing of extracting particular patterns from the respective reading subjects by performing a pattern analysis on the whole image to identify the reading subjects contained in the whole image;

a second processing module that performs processing of reading pieces of information from the respective reading subjects and recognizing the read-out pieces of information by analyzing the respective particular patterns extracted by the first processing module; and

an adding module that adds current processing statuses for the respective reading subjects contained in the whole image based on at least one of sets of processing results of the first processing module and the second processing module.

2. The information reading apparatus according to claim 1, further comprising a display controlling module that displays the current processing statuses added by the adding module on image portions of the respective reading subjects in the whole image.

3. The information reading apparatus according to claim 2, comprising a storage module that stores the whole image which is being displayed in such a manner that the current processing statuses added by the adding module are displayed on the image portions of the respective reading subjects in the whole image.

4. The information reading apparatus according to claim 1, further comprising a reading result storage module that stores, as reading results, identifiers of the respective reading subjects and the processing statuses added by the adding module in such a manner that each of the identifiers and each of the processing statuses are correlated with each other.

5. The information reading apparatus according to claim 1, further comprising a first imaging module that takes a whole image containing plural reading subjects,

wherein the acquiring module acquires the whole image taken by the first imaging module.

6. The information reading apparatus according to claim 1, further comprising a second imaging module that shoots a portion with a defect in an enlarged manner at a certain magnification when the first processing module fails to extract a particular pattern from a reading subject or the second processing module fails to recognize information from a reading subject,

wherein the first processing module extracts a particular pattern by performing a pattern analysis on an enlarged image taken by the second imaging module;

and

wherein the second processing module reads and recognizes information by analyzing the particular pattern extracted from the enlarged image by the first processing module.

7. The information reading apparatus according to claim 6, wherein the second imaging module shoots a portion with a defect in an enlarged manner at a certain magnification and the second processing module reads and recognizes information by analyzing an enlarged image taken by the second imaging module when the first processing module fails to extract a particular pattern from a reading subject or the second processing module fails to recognize information from a reading subject

8. The information reading apparatus according to claim 6, further comprising a dividing module that divides an unextracted region into blocks having certain sizes,

wherein the first processing module fails to extract a particular pattern from the unextracted region,

wherein the second imaging module shoots a portion corresponding to each of the blocks produced by the dividing module in an enlarged manner at a certain magnification,

wherein the first processing module extracts a particular pattern by performing a pattern analysis on an enlarged image taken by the second imaging module;

and

wherein the second processing module reads and recognizes information by analyzing the particular pattern extracted from the enlarged image by the first processing module.

9. The information reading apparatus according to claim 8, wherein the dividing module divides the unextracted region into blocks having certain sizes based on a size of an extracted particular pattern.

10. The information reading apparatus according to claim 6, wherein the second imaging module shoots a portion with a defect in an enlarged manner at a higher magnification that is higher than the certain magnification when the first processing module fails to extract a particular pattern from the enlarged image or the second processing module fails to recognize information by analyzing the particular pattern extracted from the enlarged image,

wherein the first processing module extracts a particular pattern by performing a pattern analysis on an enlarged image taken at the higher magnification;

and

wherein the second processing module reads and recognizes information by analyzing the particular pattern extracted from the enlarged image taken at the higher magnification by the first processing module.

11. The information reading apparatus according to claim 10, further comprising a storage module that stores the enlarged image taken at the certain magnification and the enlarged image taken at the higher magnification that is higher than the certain magnification.

12. The information reading apparatus according to claim 1, further comprising:

an information storage module that stores processing results of the second processing module; and

a storage controlling module that prevent storing into the information storage module,

wherein the acquiring module acquires plural whole images taken sequentially, the plural whole images including a first whole image and a second whole image,

wherein the second processing module performs a processing of reading and recognizing pieces of information from each of the whole images acquired by the acquiring module, and

wherein the storage controlling module prevents duplicative storage of the same information when processing results on the first whole image and the second whole image by the second processing module have the same information.

13. A computer-readable storage medium that stores a program for causing a computer to execute procedures comprising:

acquiring a whole image containing plural reading subjects;

performing first processing of extracting particular patterns from the respective reading subjects by performing a pattern analysis on the whole image to identify the reading subjects contained in the whole image;

performing second processing of recognizing pieces of information from the respective reading subjects by analyzing the respective extracted particular patterns; and

adding current processing statuses for the respective reading subjects contained in the whole image based on at least one of sets of processing results of the first processing and the second processing.
