Abstract

An information processing apparatus is provided. The apparatus registers, in a candidate list, in association with an inspection region of the reference image set on the setting screen, font data as a candidate of reference font data as a reference for character recognition at the time of inspection of a printed product, and sets the reference font data on the setting screen in accordance with a user selection from the candidate list. In the registering, among preregistered registration font data, font data whose similarity with a character string of the inspection region of the reference image exceeds a threshold is registered in the candidate list.

First claim

What is claimed is:

1. An information processing apparatus comprising:
at least one memory configured to store at least one program; and
at least one processor,
wherein the at least one program causes the at least one processor to:
(1) display, on a display, a setting screen including a preview display of a reference image,
(2) register, in a candidate list, in association with an inspection region of the reference image set on the setting screen, font data selected from among preregistered registration font data as a candidate of reference font data as a reference for character recognition at the time of inspection of a printed product, and
(3) set the reference font data in association with the inspection region on the setting screen in accordance with a user selection from the candidate list,
wherein in the registering, among the preregistered registration font data, font data whose similarity with a character string of the inspection region of the reference image exceeds a threshold is registered in the candidate list,
wherein the font data registered in the candidate list associated with a second inspection region included in another page other than a target page is used as the registration font data for generating the candidate list to be associated with an inspection region in the target page, and
wherein the second inspection region is an inspection region that has the largest overlap rate with the target inspection area in the target page and the overlap rate exceeds a threshold value in case where the target page is arranged to overlap the another page.

2. The apparatus according to claim 1 , wherein in the registering, if there is no font data whose similarity exceeds the threshold, all the registration font data are registered in the candidate list.

3. The apparatus according to claim 2 , wherein in the registering, if there is no font data whose similarity exceeds the threshold, the user is notified that there is no font data to be registered in the candidate list.

4. The apparatus according to claim 1 , wherein in the registering, character recognition is performed for the inspection region with reference to the registration font data, and the font data whose similarity exceeds the threshold is registered in the candidate list.

5. The apparatus according to claim 1 , wherein the at least one program causes the at least one processor to:
(1) further set, in the setting, whether to display the candidate list at the time of setting the reference font data, and
(2) register, in the registering, all the registration font data in the candidate list if it is not set to display the candidate list.

6. The apparatus according to claim 1 , wherein the at least one program causes the at least one processor to further register, as the registration font data, a character image selected from an image displayed on the display.

7. The apparatus according to claim 1 , wherein in the setting, names of the font data included in the candidate list are displayed as a list, and the font data selected from the list is set as the reference font data.

8. An inspection system comprising:
an information processing apparatus;
an image forming apparatus; and
an inspection apparatus configured to inspect, using reference font data set by a setting unit, a character image formed by the image forming apparatus,
wherein the information processing apparatus comprises
(A) at least one memory configured to store at least one program, and
(B) at least one processor,
wherein the at least one program causes the at least one processor to
(1) display, on a display, a setting screen including a preview display of a reference image,
(2) register, in a candidate list, in association with an inspection region of the reference image set on the setting screen, font data selected from among preregistered registration font data as a candidate of reference font data as a reference for character recognition at the time of inspection of a printed product, and
(3) set the reference font data in association with the inspection region on the setting screen in accordance with a user selection from the candidate list,
wherein in the registering, among the preregistered registration font data, font data whose similarity with a character string of the inspection region of the reference image exceeds a threshold is registered in the candidate list,
wherein the font data registered in the candidate list associated with a second inspection region included in another page other than a target page is used as the registration font data for generating the candidate list to be associated with an inspection region in the target page, and
wherein the second inspection region is an inspection region that has the largest overlap rate with the target inspection area in the target page and the overlap rate exceeds a threshold value in case where the target page is arranged to overlap the another page.

9. A non-transitory computer-readable storage medium storing thereon a program which, when loaded into a computer and executed, causes the computer to execute a process, the process comprising:
displaying, on a display, a setting screen including a preview display of a reference image;
registering, in a candidate list, in association with an inspection region of the reference image set on the setting screen, font data selected from among preregistered registration font data as a candidate of reference font data as a reference for character recognition at the time of inspection of a printed product; and
setting the reference font data in association with the inspection region on the setting screen in accordance with a user selection from the candidate list,
wherein in the registering, among the preregistered registration font data, font data whose similarity with a character string of the inspection region of the reference image exceeds a threshold is registered in the candidate list,
wherein the font data registered in the candidate list associated with a second inspection region included in another page other than a target page is used as the registration font data for generating the candidate list to be associated with an inspection region in the target page, and
wherein the second inspection region is an inspection region that has the largest overlap rate with the target inspection area in the target page and the overlap rate exceeds a threshold value in case where the target page is arranged to overlap the another page.

10. A setting method for inspection of an image by an information processing apparatus including a preview unit, a registration unit, and a setting unit,
wherein the information processing apparatus
(1) displays, on a display, a setting screen including a preview display of a reference image,
(2) registers, in a candidate list, in association with an inspection region of the reference image set on the setting screen, font data selected from among preregistered registration font data as a candidate of reference font data as a reference for character recognition at the time of inspection of a printed product,
(3) sets the reference font data in association with the inspection region on the setting screen in accordance with a user selection from the candidate list, and
(4) registers, at the time of registering the font data in the candidate list, among the preregistered registration font data, font data whose similarity with a character string of the inspection region of the reference image exceeds a threshold in the candidate list,
wherein the font data registered in the candidate list associated with a second inspection region included in another page other than a target page is used as the registration font data for gene
