IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
First Claim
1. An image processing apparatus comprising:
- an interface unit for acquiring a readout image produced by capturing an image formed on a medium;
a storage unit for storing a plurality of templates generated by superimposing different amounts of blurring on a prescribed pattern contained in said image, and for storing the amounts of blurring superimposed on said plurality of templates, respectively; and
a processing unit adapted to detect a pattern region where said prescribed pattern is located on said readout image,calculate the degree of matching between said pattern region and each of said plurality of templates and, based on said degree of matching, identify from among said plurality of templates a template that most closely matches said prescribed pattern located on said readout image, andestimate that the amount of blurring corresponding to said most closely matching template represents the amount of blurring superimposed on said readout image.

Abstract
An image processing apparatus includes: an interface unit for acquiring a readout image produced by capturing an image formed on a medium; a storage unit for storing a plurality of templates generated by superimposing different amounts of blurring on a prescribed pattern contained in the image, and for storing the amounts of blurring superimposed on the respective templates; and a processing unit adapted to detect a pattern region where the prescribed pattern is located on the readout image, calculate the degree of matching between the pattern region and each of the plurality of templates and, based on the degree of matching, identify a template that most closely matches the prescribed pattern located on the readout image, and estimate that the amount of blurring corresponding to the most closely matching template represents the amount of blurring superimposed on the readout image.

8. An image processing method comprising:
-
acquiring a readout image produced by capturing an image formed on a medium; detecting a pattern region where a prescribed pattern contained in said image is located on said readout image; calculating the degree of matching between said pattern region and each of a plurality of templates generated by superimposing different amounts of blurring on said prescribed pattern and, based on said degree of matching, identifying from among said plurality of templates a template that most closely matches said prescribed pattern located on said readout image; and estimating that the amount of blurring corresponding to said most closely matching template represents the amount of blurring superimposed on said readout image.

9. A computer readable recording medium having an image processing computer program recorded thereon for causing a computer to:
-
acquire a readout image produced by capturing an image formed on a medium; detect a pattern region where a prescribed pattern contained in said image is located on said readout image; calculate the degree of matching between said pattern region and each of a plurality of templates generated by superimposing different amounts of blurring on said prescribed pattern and, based on said degree of matching, identify from among said plurality of templates a template that most closely matches said prescribed pattern located on said readout image; and estimate that the amount of blurring corresponding to said most closely matching template represents the amount of blurring superimposed on said readout image.
