Abstract

In the case where a table region is erroneously recognized, the edition of a character is facilitated. An information processing apparatus selects one selectable region from an image. According to the change of the position of the region selected by a selecting unit, a region that is included in the region before the position change and that is not included in the region after the position change is set to a new selectable region.

First claim

What is claimed is:

1. An information processing apparatus comprising:
a memory; and
at least one processor in communication with the memory, wherein the at least one processor performs:
executing an image analysis of a document image to identify cells within a table region included in the document image;
controlling to display the document image and frames corresponding to the identified cells, wherein the frames are displayed on the displayed document image;
selecting, based on a user instruction, one frame from the displayed frames;
controlling to further display handles for changing position of the selected one frame when the one frame is selected based on the user instruction;
changing the position of the selected one frame based on a user operation of the displayed handles;
determining whether the selected one frame is reduced beyond at least one character of characters included in the selected one frame by the change of the position of the selected one frame based on the user operation of the displayed handles; and
automatically generating, when it is determined that the selected one frame is reduced beyond at least one character of characters included in the selected one frame, a new frame which includes at least one character in the selected one frame and which does not include at least one character in an area except the reduced frame, wherein the new frame is not generated automatically when it is determined that the selected one frame is not reduced beyond at least one character of characters included in the selected one frame.

2. The information processing apparatus according to claim 1 ,
wherein a first character included in the reduced frame is associated with the new frame.

3. The information processing apparatus according to claim 2 ,
wherein the at least one processor further performs generating another new frame including at least one character in the area except the reduced frame.

4. The information processing apparatus according to claim 1 ,
wherein each of the cells that are identified by the image analysis of the document image is a circumscribed rectangle of a white pixel block within the table region.

5. The information processing apparatus according to claim 1 ,
wherein the document image is obtained by scanning a document.

6. The information processing apparatus according to claim 1 ,
wherein the at least one processor further performs coupling, if the selected one frame is enlarged by the change of the position of the selected one frame based on a user operation of the displayed handles and the enlarged frame includes another frame, the enlarged frame and the another frame included in the enlarged frame.

7. The information processing apparatus according to claim 1 ,
wherein the position of the reduced frame is automatically aligned to a position of a ruled line of the table region if a position changed based on the user operation of the displayed handles is approximately equal to the position of the ruled line of the table region.

8. A non-transitory computer-readable medium storing an application program for controlling a computer to:
execute an image analysis of a document image to identify cells within a table region included in the document image;
display the document image and frames corresponding to the identified cells, wherein the frames are displayed on the displayed document image;
select, based on a user instruction, one frame from the displayed frames;
display handles for changing position of the selected one frame when the one frame is selected based on the user instruction;
change the position of the selected one frame based on a user operation of the displayed handles;
determine whether the selected one frame is reduced beyond at least one character of characters included in the selected one frame by the change of the position of the selected one frame based on the user operation of the displayed handles; and
automatically generate, when it is determined that the selected one frame is reduced beyond at least one character of characters included in the selected one frame a new frame which includes at least one character in the selected one frame and which does not include at least one character in an area except the reduced frame, wherein the new frame is not generated automatically when it is determined that the selected one frame is not reduced beyond at least one character of characters included in the selected one frame.
