Abstract
Abstract A family register document is divided into a plurality of regions, and the type of family register document is identified on the basis of the features of the divided regions. The division result is checked on the basis of stored format information of the family register document corresponding to the identified type. In accordance with another embodiment of the invention, after a family register document is divided into a plurality of regions, characters present in the divided regions are recognized. The recognition result is compared with stored character information, and the type of family register document is identified based on a result of this comparison. According to another embodiment of the invention, ruled lines included in a family register document are extracted, and the type of family register document is identified based on features of the extracted ruled lines. The extraction result is checked based on format information of the family register document corresponding to the identified type. Furthermore, the discrimination result is informed. In a further embodiment, after a family register document is divided into a plurality of regions, and the type of family register document is identified based on features of the divided regions, format information of the family register document corresponding to the identified type is assigned to each of the divided regions, and characters present in the assigned regions are recognized.

Claim 6
Dependent Claim
37 words
The apparatus according to claim 1 , further comprising: correction means for correcting an error in the division result, when a discrimination result of said discriminator indicates that the division result of said divider includes an error.
Claim 7
Dependent Claim
22 words
The apparatus according to claim 1 , further comprising: a display for displaying a result of the discrimination performed by said discriminator.
Claim 8
Dependent Claim
36 words
The apparatus according to claim 1 , further comprising: information means for providing message information indicating an error, when a discrimination result of said discriminator indicates that the division result of said divider includes an error.
Claim 9
Dependent Claim
20 words
The apparatus according to claim 1 , wherein each of the regions is a rectangular region surrounded by ruled lines.
Claim 10
Dependent Claim
57 words
The apparatus according to claim 1 , further comprising: a display for displaying the region which may have caused an error in the division result to be distinguished from the regions free from the error in the division result, when a discrimination result of said discriminator indicates that the division result of said divider includes an error.
Claim 11
Dependent Claim
31 words
The apparatus according to claim 1 , wherein said discriminator performs the discrimination on the basis of a comparison between a part of the plurality of regions and the format information.
Claim 12
Dependent Claim
32 words
The apparatus according to claim 1 , wherein said discriminator performs the discrimination on the basis of a comparison between a key region in the plurality of regions and the format information.
Claim 13
Dependent Claim
80 words
An image processing method, comprising the steps of: an input step of inputting an image; a division step of dividing the input image into a plurality of regions; a determination step of determining features of the regions; and a discrimination step of automatically discriminating whether or not a result of the division has an error, on the basis of a comparison between the features of the regions and format information associated with a predetermined format stored in a format dictionary.
Claim 14
Dependent Claim
