Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) The present invention relates to a format control information processing device for a character reading device that performs registration processing of format control information necessary for character reading processing.

(Prior Art) Conventionally, in an optical character reader (OCR), format control information (FC information) is registered in advance, and based on this FC information, characters recorded on a form to be read are recognized. will be done. The FC information is, for example, control information such as reading line position information on a form, form size, type of recorded characters, character pitch, and font.

By the way, as a method for previously registering FC information in OCR, there is a method in which necessary information is recorded on a control sheet and this control sheet is read into OCR.

The control sheet consists of a header sheet recording header information according to the reading processing mode and a detail sheet recording detail information. Usually, one header sheet is combined with a plurality of detail sheets. The header information is, for example, information about the entire job and processing mode, and the detail information is information about, for example, a form, print style, CRT screen, output editing, etc. in a predetermined job and processing mode.

Here, in conventional OCR, there is one processing mode in one job, and therefore the correlation between header information and detail information is also one specified one. Therefore, when registering FC information in which the correlation between header information and detail information is variable, it is necessary to create and register a plurality of jobs according to the number of combinations.

In addition, in the registration process, OCR is used from the control sheet as described above.
Object information that can be internally processed is created, but as the number of jobs to be registered increases, the number of object information ports also increases.

(Problem to be solved by the invention) In the conventional FC information registration method, job, processing mode,
Since the correlation between header information and detail information is fixed, when registering FC information whose correlation is variable, the registration process takes a lot of time, resulting in lower processing efficiency. Another drawback is that the amount of object information that can be processed within OCR increases significantly.

The purpose of the present invention is to
A character reading device that can efficiently set the correlation between jobs, processing modes, header information, and detail information in a variable manner without particularly increasing the amount of FC information when registering C information. An object of the present invention is to provide a format control information processing device.

[Structure of the Invention] (Means and Effects for Solving the Problems) The present invention provides a character reading device that performs a process of registering format control information for setting header information and detail information for each mode of character reading processing. format! In the control information processing device, a SEQ table stores a header information group corresponding to the type of detail information for each mode, a mode table for selecting and specifying the SEQ table according to each mode, and 81D of header information and detail information. This device includes a flag indicating the presence or absence of information and an ID table having information for indicating the correlation between header information and detail information on the SEQ table.

Such configuration allows jobs, processing modes.

It becomes possible to ensure the correlation between header information and detail information, and to efficiently register FC information in which the correlation is varied.

(Example) The present invention will be described in detail below with reference to the drawings. FIG. 1 and FIG. 2 are block diagrams relating to the same embodiment, respectively. First, an OCR (character reading device) is roughly divided into a control section 20, a scanning system 21, a recognition section 22, and a dictionary memory 23, as shown in FIG.

The scanning system 21 includes a photoelectric conversion element such as a CCD, and optically scans a form to be read to output a character pattern. The recognition unit 22 performs matching processing on the character pattern generated by the scanning system 2■ with dictionary information (standard pattern) stored in advance in the dictionary memory 23, and outputs the recognition result (corresponding character code). do. In this case, the recognition unit 22 performs character recognition processing based on format control information (FC information) output from the control unit 20.

The control unit 20 controls the operation of the entire OCR, and
This circuit performs FC information registration processing, which is the gist of the present invention, and includes a microprocessor (CPU).

FIG. 1 is a block diagram showing a conceptual configuration related to the FC information registration function of the control unit 20 of the same embodiment. CPU
10 performs registration processing of FC information necessary for OCR reading processing based on various control information 11 to I3 given from the outside by a control sheet. Here, control information 11
consists of, for example, the mode name of the processing mode and information that can be set for each mode. The control information I2 is, for example, the ID number of the header sheet, the maximum number of forms read, and the ID number of the detail sheet. Furthermore, the control information I3 is, for example, ID information. This ID information is various information in the form reading process, such as data check, editing nine-screen format, output format, and form reading mode.

CPU10 creates a mode table 11 as shown in FIG. 3 using control information 11 given from the outside.

Furthermore, CPU10 receives control information from the outside! 2
Accordingly, 12 SEQ (sequence) tables as shown in FIG. 4 are created.

The SEQ table 12 is created for each mode name shown in FIG. FIG. 4 shows the SEQ table 12 corresponding to mode name 1.

Furthermore, the CPU 10 receives control information I2. I3 creates an ID table 13 as shown in FIG. In this ID table 13, ID name and SEQ table 1
2 SEQ numbers correspond. For example, ID name (HO
looO) is the ID number of the header information, and corresponds to the SEQ number (01).

Further, for example, the ID name (DO1020) is the ID number of detail information and corresponds to the SEQ number (05). CPU to receives ID information (control information 1) from the outside.
3), the flag of the corresponding ID name is set to "1" in the ID table 13 of FIG. Then, the CPU 10 registers the given ID information in the ID information memory 14 as a real ID. Furthermore, when ID information is deleted from the ID information memory 14, CPU10
sets the flag of the corresponding ID name in the ID table in Figure 5 to "0".
”. At this time, the ID name will be left as is without being deleted.

Next, when performing a reading process on a predetermined document to be read, a processing mode for a predetermined job is specified using a mode name. The mode name is specified by, for example, displaying the mode name corresponding to the processing mode on the CR7 screen at the start of reading, and selecting and specifying it on this screen. CPU10 refers to the SEQ table 12 corresponding to the specified mode name. CPU 1
0 limits the range of the SEQ number (for example, 01 or 02) of the header ID by the SEQ table 12. Next, when the header ID name (number) is specified, the CPU 1O obtains the SEQ number using the ID table 13 shown in FIG. In this case, if the presence/absence flag is "0", an error process will be performed as an undefined ID. Also, the obtained SEQ number is SEQ
If it is outside the range specified in table 12, it will be treated as an undefined TD and an error will be processed.

If ID information exists in determining the header ID name and presence/absence flag, the CPU 10 performs SEQ in FIG.
Header by table 12! Check the detail ID corresponding to D. That is, it is determined whether the SEQ number corresponding to the specified detail ID is registered. If it is not registered, an error will be processed as an undefined ID. In this case, the maximum number of sheets to be read is checked in the SEQ table 12 of FIG.

In this way, in a predetermined processing mode (specified by a mode name) in a predetermined job, header ID information corresponding to a header ID number and a plurality of detail ID numbers correlated with this header ID information are handled. Detail ID information can be registered. That is, for each processing mode, FC information consisting of a plurality of combinations of correlated header ID information and detail ID information can be easily registered. Therefore, in OCR, various reading processes can be performed based on FC information corresponding to each processing mode. In addition, since there is no need to create FC information consisting of a combination of header ID information and detail ID information for each processing mode, the overall
C information 2 will not increase significantly.

In the above embodiment, in the self-processing mode of the correlation between the header ID information and the detail ID information, checking is not necessary due to the SEQ table 12 shown in FIG. In this case, the presence/absence of ID information registration in the ID table 13 of FIG. 5 is simply determined based on the presence/absence flag.

[Effects of the Invention] As detailed above, according to the present invention, in the OCR format control information registration method, F.
When registering C information, jobs and processing modes can be changed without increasing the number of FC information ports.

It is possible to efficiently set the correlation between header information and detail information in a variable manner. Therefore, it is possible to easily and reliably perform character reading processing in various processing modes.
