1. An information processing apparatus comprising

a processor configured to

acquire, from a read image, a predetermined item, and a value corresponding to the item, the read image being obtained by reading a document, the read image being subjected, prior to acquisition of the item and the value, to preprocessing and character recognition, and

in response to not successfully acquiring at least one of the item and the value, change a setting on the preprocessing or a setting on the character recognition in accordance with an acquisition or non-acquisition state of the item and the value, and then perform the preprocessing or the character recognition,

wherein the processor is configured to, in response to successfully acquiring the item and the value and determining that the acquired value does not correspond to the item, perform the preprocessing or the character recognition.

2. The information processing apparatus according to claim 1 ,

wherein the processor is configured to previously store a candidate of the value corresponding to the item, and if the candidate and the value are not considered as identical, determine that the value does not correspond to the item.

3. The information processing apparatus according to claim 2 ,

wherein the preprocessing comprises a plurality of predetermined processes, and

wherein the processor is configured to, in response to not successfully acquiring at least one of the item and the value from a result of the preprocessing performed with the setting changed and from a result of the character recognition performed with the setting changed, again perform preprocessing different from the preprocessing, or character recognition different from the character recognition.

4. The information processing apparatus according to claim 3 ,

wherein the processor is configured to, in response to applying all of the plurality of processes and not successfully acquiring at least one of the item and the value from a result of the character recognition performed with the plurality of processes applied, provide notification of a failure to acquire the item and the value.

5. The information processing apparatus according to claim 2 ,

wherein the processor is configured to, in response to not successfully acquiring at least one of the item and the value, identify where the item and the value are located.

6. The information processing apparatus according to claim 1 ,

wherein the preprocessing comprises a plurality of predetermined processes, and

wherein the processor is configured to, in response to not successfully acquiring at least one of the item and the value from a result of the preprocessing performed with the setting changed or from a result of the character recognition performed with the setting changed, again perform preprocessing different from the preprocessing, or character recognition different from the character recognition.

7. The information processing apparatus according to claim 6 ,

wherein the processor is configured to, in response to applying all of the plurality of processes and not successfully acquiring at least one of the item and the value from a result of the character recognition performed with the plurality of processes applied, provide notification of a failure to acquire the item and the value.

8. The information processing apparatus according to claim 6 ,

wherein the processor is configured to, in response to not successfully acquiring at least one of the item and the value, identify where the item and the value are located.

9. The information processing apparatus according to claim 1 ,

wherein the processor is configured to, in response to not successfully acquiring at least one of the item and the value, identify where the item and the value are located.

10. The information processing apparatus according to claim 9 ,

wherein the processor is configured to, in response to not successfully acquiring the item and the value, determine whether an item and a value located in an area different from the item and the value have been successfully acquired.

11. The information processing apparatus according to claim 10 ,

wherein the processor is configured to, in response to successfully acquiring the item and the value located in the different area, change a setting on removal of a background pattern and a watermark.

12. The information processing apparatus according to claim 1 ,

wherein each of the preprocessing and the character recognition comprises a plurality of processes, and a priority is set for each of the plurality of processes, and

wherein the processor is configured to change the at least one setting in accordance with the priority.

13. An information processing system comprising:

an information processing apparatus including a processor, the processor being configured to

acquire, from a read image, a predetermined item, and a value corresponding to the item, the read image being obtained by reading a document, the read image being subjected, prior to acquisition of the item and the value, to preprocessing and character recognition, and

in response to not successfully acquiring at least one of the item and the value, change a setting on the preprocessing or a setting on the character recognition in accordance with an acquisition or non-acquisition state of the item and the value, and then perform the preprocessing or the character recognition,

wherein the processor is configured to, in response to successfully acquiring the item and the value and determining that the acquired value does not correspond to the item, perform the preprocessing or the character recognition;

a preprocessing apparatus that performs the preprocessing; and

a character recognition apparatus that performs the character recognition,

the preprocessing apparatus and the character recognition apparatus performing, in response to an instruction from the information processing apparatus, processing for facilitating character recognition.

14. The information processing system according to claim 13 ,

wherein the processing for facilitating character recognition includes at least one of removal of a background pattern, removal of a watermark, inversion of white-on-black text, removal of shading, removal of a colored background, changing of a dictionary, and changing of an OCR engine.

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

acquiring, from a read image, a predetermined item, and a value corresponding to the item, the read image being obtained by reading a document, the read image being subjected, prior to acquisition of the item and the value, to preprocessing and character recognition;

in response to not successfully acquiring at least one of the item and the value, changing a setting on the preprocessing or a setting on the character recognition in accordance with an acquisition or non-acquisition state of the item and the value, and then performing the preprocessing or the character recognition; and

in response to successfully acquiring the item and the value and determining that the acquired value does not correspond to the item, perform the preprocessing or the character recognition.
