As shown in FIG. 3C, image data captured by the CCD camera 10a is read from the image data storage unit 9c and displayed on the data processing screen.

The character recognizing unit 1a refers to the dictionary table 8b and recognizes the captured image data as characters, and temporarily stores the image data as recognition data in the recognition data storage unit 9d. The attribute determining unit 1b refers to the attribute data table 8c to determine an attribute item of the recognition data, and stores the attribute item in the reference data storage unit 9e as address book data to which the attribute item is added. The comparing unit 1c compares the data in the target data storage unit 9f with the data in the reference data storage unit 9e for each attribute item.

For example, here, in the “affiliation” item,
Character data "translation center" is stored in the target data storage unit 9f.
Is stored, and reference data “software development unit” is stored in the reference data storage unit 9e. As a result of the comparison,
Since the character data “translation center” does not match the reference data “software development department”, the reference data “software development department” is specified as character data to be updated.

FIG. 4 is a view showing an example of the data processing screen (2) according to this embodiment. As shown in FIG. 4A, an update content confirmation window 33 is displayed to prompt the user to make a change. Under "Affiliation" item, "Translation Center"

FIG. 5 is a diagram showing the character positions of a business card used in this embodiment. As shown in FIG. 5, in general, three patterns are often found in the character layout (layout) of a business card, and in many cases, personal names are often described in the largest type (font). FIG. 5A shows a horizontal business card printed in horizontal writing, FIG. 5B shows a vertical business card printed in vertical writing, and FIG. 5C shows a vertical business card. It was printed in horizontal writing.

In order to recognize the characters of the photographed image data, first, characters having the largest font are cut out.
Next, it is determined from the extracted characters whether the text is written vertically or horizontally. A well-known method is used for the character extraction processing and the determination of vertical writing and horizontal writing. For example, in the character cutout process, one horizontal row of pixels is taken out and the sum is obtained.
There is a method of summing the pixels in the vertical column of the portion where the total is large, and setting the large portion as a region where the character exists.

For example, the determination of vertical writing and horizontal writing is as follows.
There is a method of detecting the width of the line and the width between characters in each rectangle by utilizing the fact that the line spacing is wider than the character spacing, and comparing the two to determine the character direction. The character string 50, which is the largest font cut out, is recognized with reference to the dictionary table 8b based on the determination whether the vertical writing is horizontal writing, and is stored in the recognition data storage unit 9d of the RAM 9.

Next, if the image is written horizontally, the character string 51 above the character string 50 having the largest font is cut out and character recognition is performed by referring to the dictionary memory unit 8b, and is stored in the recognition data storage unit 9d of the RAM 9. Remember. When the image is written vertically, the character string 52 on the right side of the character string 50 having the largest font is cut out and character-recognized and stored in the recognition data storage unit 9d of the RAM 9.

Further, another character string group is cut out and, after character recognition, temporarily stored in the recognition data storage section 9d. The recognition data stored in the recognition data storage unit 9d is compared with the attribute data stored in the attribute data table 8c for each row, and a matching attribute is specified, the attribute is added, and stored in the reference data storage unit 9e. You.

FIG. 6 is a diagram showing the storage contents of the attribute data table according to this embodiment. As shown in FIG.
When the attribute content matches the attribute content of the symbol table 8c-1, the numerical value immediately after the matched character string is stored in the reference data storage unit 9e as company TEL data. FAX symbol table 8
If the content matches the content of c-2, the numerical value immediately after the matched character string is used as company fax data in the reference data storage unit 9e.
To memorize. It should be noted that, in order to identify a telephone number, the fact that numbers are arranged in a certain number or more may be used as a judgment standard.

If the contents match the contents of the group symbol table 8c-3, the entire matched character string is stored in the reference data storage section 9e as company name data. Post code table 8c
In the case where the contents match with the contents of -4, the matched position is stored in the reference data storage unit 9e as position data. If the contents match the contents of the place name symbol table 8c-5, the entire matched character string is stored in the reference data storage unit 9e as company address data. If the contents match the contents of the postal symbol table 8c-6, the numerical value immediately after the matched character string is stored in the reference data storage unit 9e as company postal data.

If the contents match the contents of the mail symbol table 8c-7, the alphabet or numerical value immediately after the matched character string is stored in the reference data storage section 9e as mail address data. If the contents match the contents of the URL symbol table 8c-8, the alphabet or numerical value immediately after the matched character string is stored in the reference data storage unit 9e as URL data. When the attribute is specified by this data processing, the recognition data is stored in the reference data storage unit 9e together with the corresponding attribute.

The comparing section 1c compares the reference data in the reference data storage section 9f with the character data in the target data storage section 9f selected by the user for each item, thereby detecting non-matching data as update data. An update content confirmation window is displayed (FIG. 4A).

At this point, the user selects "O" on the update content confirmation screen.
When the "K button" is checked, a confirmation signal is output from the tablet control unit 3 to the update unit 1d, and the update unit 1d that has received the confirmation signal updates the target data in the target data storage unit 9f, and updates the main data storage unit 9a.

Step S43: It is determined whether or not all items have been compared. If comparison has not been performed for all items, the process returns to step S33, and the processing from step S33 to step S43 is repeated until the comparison is completed for all items. If all items have been compared, the process ends.

When updating the address book data stored with the attribute added in advance to the main data storage unit, if the read address book data does not include the same personal name data as the personal name data in the reference data storage unit 9e. Since the recognition data (personal name data) can be stored as new address book data in the main data storage unit 9a (database), the same data can be prevented from being registered repeatedly.

Although the personal name data is used as a keyword (attribute) to match the existing address book data with the fetched image recognition data, the personal name may be updated. Therefore, in that case, another attribute such as a company name may be used as a keyword. When data common to a plurality of persons, such as a company name and a company address, is updated, other data may be updated accordingly.

Although the contents of the present invention have been described using the main data storage section as a database and a stored address book as an example, the same means can be applied to data correction for databases having other data contents. Needless to say, the processing is possible.

According to the present invention, when updating the character data stored in the character data storage unit with the attribute added thereto in advance, the character image data is read from the paper on which the character is recorded by the image reading unit. Thus, the character data to be updated can be automatically determined and updated. Therefore, it is possible to easily and quickly change or modify the contents of the address book or the like, which is conventionally troublesome.
