Japanese Patent Laid-Open No. 9-259221

  However, there are some forms that are horizontally long because they are composed of delivery notices, original marks, receipts, etc., as in the case of tax public funds, and the entire form does not fit within the scanning area of the scanner. . When such a form is read by a scanner, the size of the form area included in the image data varies each time the form is read. Therefore, in an apparatus that generates ruled line feature information composed of N × M ruled line features by dividing a ruled line pattern image into an N × M matrix as in the above apparatus, image data that does not include the entire form is stored. In this case, the division size of the ruled line pattern is changed, so that the identification success rate is lowered.

  In view of the above problems, the object of the present invention is to extract a ruled line pattern from image data of a form having a ruled line, and to identify the form format based on the extracted ruled line pattern, including the entire form. An object of the present invention is to provide a form processing apparatus capable of improving the form-form identification performance even with no image data.

The present invention adopts the following configuration in order to solve the above points.
The form processing apparatus according to the present invention is a protrusion determination that determines whether or not an image of the entire form is acquired from the form image data in the form processing apparatus including a generation unit that generates feature information influenced by the external dimensions of the form. A complementary image data processing unit for generating complementary image data by adding complementary image data of a predetermined size to the form image data when it is determined that an image of the entire form has not been acquired. It supplies to a part.

  In the above configuration, the form processing apparatus determines the form format by comparing the feature information storage unit in which the feature information for each form is registered with the generated feature information and the registered feature information in the feature information storage unit. And a portion.

  The feature information is characterized by ruled line feature information of the form.

  The generation unit divides a form image data acquired from a form provided with ruled lines into a plurality of N × M matrices, and generates ruled line feature information indicating the characteristics of the ruled lines for each divided block. .

  The registered feature information in the ruled line feature information storage unit is generated based on complementary image data obtained through the protrusion determination unit and the image complement processing unit.

  It further includes a ruled line pattern image generation unit that converts the complementary image data into a ruled line pattern image showing only ruled lines and supplies the ruled line pattern image to the generation unit.

  According to the present invention, in a form processing apparatus that extracts a ruled line pattern from image data of a form having a ruled line and identifies a form format based on the extracted ruled line pattern, image data is included in the image data that does not include the entire form. Since it complements, the identification performance in identifying a form format can be improved.

  Hereinafter, embodiments of the present invention will be described in detail using examples.

<Configuration of Example>
A form processing apparatus 100 according to an embodiment of the present invention is connected to an image reading apparatus 200 via a network 10 as shown in FIG. Here, the form processing apparatus 100 is installed in a financial institution, for example, and is used for the process of identifying the form format based on the ruled line pattern described in the form 1.

  The image reading apparatus 200 is an apparatus that optically reads the form 1 and outputs it as image data. In other words, when the image reading apparatus 200 receives an image request signal (to be described later) from the form processing apparatus 100, the image reading apparatus 200 optically scans the form 1 set in a reading unit (not shown) of the apparatus to quantize, for example, black and white binary. The image data consisting of the electrical signal is generated. In this image data, the ruled lines and characters of the form 1 are represented by black bits, and the paper portion of the form 1 is represented by white bits. In the image data, the background area excluding the area of the form 1 is represented by black bits. Here, the image reading apparatus 200 is, for example, a stand type scanner. The image data generated by the image reading apparatus 200 is transmitted to the form processing apparatus 100 under the control of a control unit (not shown).

  The form processing apparatus 100 is an apparatus operated by an operator for registering and identifying the form format of the form 1 from the image data of the form 1, and the communication unit 101 connected to the image reading apparatus 200 via the network 10. The control unit 102 that controls the entire apparatus, the temporary storage unit 103, the display unit 104, the input unit 105, the image data storage unit 106, the protrusion determination unit 107, the image complement processing unit 108, and a ruled line pattern image A generation unit 109, a ruled line feature information generation unit 110, a registered ruled line feature information DB 111, a registered ruled line feature information management unit 112, and a form format determination unit 113 are provided.

  The image data storage unit 106 is a storage unit that stores image data acquired from the image reading apparatus 200.

  When an operator operating the form processing apparatus 100 instructs to read the image data of the form 1 set in the image reading apparatus 200 via the keyboard provided in the input unit 105, the control unit 102 generates and generates an image request signal. An image request signal is transmitted to the image reading apparatus 200.

  When the control unit 102 acquires image data from the image reading apparatus 200 as a response to the image request signal, the control unit 102 stores the acquired image data in the image data storage unit 106. Then, when the image data is stored, the control unit 102 executes a control program in a memory (not shown), and displays an image data display screen for allowing the operator to refer to the image data on a display provided in the display unit 104.

  When the operator who operates the form processing apparatus 100 indicates that the form 1 displayed on the image data display screen is a registration form, the registration of the form format is instructed to the image data via the keyboard provided in the input unit 105. The control unit 102 executes a memory control program (not shown) to display a form identification number input instruction screen for allowing the operator to input a form identification number for identifying the form 1 on a display provided in the display unit 104.

  The operator then refers to the form identification number input instruction screen displayed on the display unit 104 of the form processing apparatus 100 and inputs the form identification number for identifying the form 1 from the keyboard provided in the input unit 105. When the “registration” button, for example, on the identification number input instruction screen is pressed, the control unit 102 stores the acquired form identification number in the temporary storage unit 103 and also stores the image data of the registration form 1 in the protrusion determination unit 107. Instructs the protrusion judgment. In this embodiment, the operator inputs the form identification number for identifying the form 1 at the time of registration via the input unit 105. However, a form identification number (form ID etc.) is previously stored in the registration form 1 itself. A form identification unit (not shown) that is provided may automatically identify the form 1.

  On the other hand, an operator who operates the form processing apparatus 100 issues an instruction to determine the form format of the image data of the identification form 1 as the processing target displayed on the image data display screen via the keyboard provided in the input unit 105. Then, the control unit 102 instructs the protrusion determination unit 107 to determine whether the image data of the identification form 1 is protruding.

  When the image reading apparatus 200 reads the form 1 from the form area included in the image data, the protrusion determination unit 107 does not fit within the photographing area of the apparatus as shown in FIG. It is the determination part which determines whether it had been. In other words, when the protrusion determination unit 107 receives an instruction to determine the protrusion, it scans the image data held in the temporary storage unit 103, and if a white pixel exists at the image end of the image data as shown in FIG. Judge that there is. When the protrusion determination unit 107 determines that the protrusion is present, the control unit 102 instructs the image complement processing unit 108 to perform image complement processing.

  On the other hand, the protrusion determination unit 107 determines that there is no protrusion when there is no white pixel at the image end of the image data. When the protrusion determination unit 107 determines that there is no protrusion, the control unit 102 instructs the ruled line pattern image generation unit 109 to generate a ruled line pattern image and transfers the image data held in the image data storage unit 106.

  As shown in FIG. 2, the image complement processing unit 108 has a protruding portion due to the large length of the form 1, and image data in the middle part of the form as shown in FIG. If it is obtained, a complementary area to be complemented is generated so that the size in the length direction of the middle part of the form becomes a preset size (210 mm) as shown in FIG. It is a processing unit that generates complementary image data combining the complementary regions. That is, when receiving the instruction for the image complementing process, the image complementing processing unit 108 first scans the image data held in the temporary storage unit 103, and the four vertices “LT” constituting the middle part of the form as shown in FIG. (LTx, LTy), LB (LBx, LBy), RT (RTx, RTy), and RB (RBx, RBy) ”, and since a white pixel exists at the right end of the image data, the protruding direction is set to the right. get.

  Next, the image complementation processing unit 108 calculates the size in the length direction of the mid-form of the image data, and sets the A4 horizontal size (210 mm) set in advance and the size in the length direction of the mid-form area. The size in the length direction of the complementary region is calculated from the difference between the two. Here, 210 mm is, for example, 210 × 240 / 25.4≈1984 dots on an image having a resolution of 240 dpi. Therefore, if the size in the length direction of the intermediate area of the form is, for example, 1500 dots, the image complement processing unit 108 The size of the complementary region in the length direction is calculated to be 1984 dots-1500 dots = 484 dots.

  Then, when the image complement processing unit 108 calculates the size (484 dots) of the length dimension of the complement region, the coordinates of four vertices “RT (RTx, RTy), RB (RBx, RBy), R as shown in FIG. A complementary region constituted by “T (RTx + 484, RTy), R′B (RBx + 484, RBy)” is generated. Here, the complement region is entirely composed of white pixels.

  When the complement region is generated, the image complement processing unit 108 generates complement image data as shown in FIG. 6 in which the complement region is combined with the mid-form region of the image data. Here, in the complementary image data, the background part excluding the form area is composed entirely of black pixels.

  When the image complement processing unit 108 generates complement image data, the control unit 102 stores the complement image data in the temporary storage unit 103. Then, after storing the complementary image data, the control unit 102 instructs the ruled line pattern image generation unit 109 to generate a ruled line pattern image and transfers the complementary image data.

  The ruled line pattern image generation unit 109 extracts ruled line pattern image data indicating only the ruled line pattern by extracting only the ruled line part excluding characters included in either the image data stored in the image data storage unit 106 or the complementary image data. It is the production | generation part to produce | generate. That is, when the ruled line pattern image generation unit 109 receives the image data of the registration form 1 together with an instruction to generate the ruled line pattern image information, the ruled line pattern image generation unit 109 scans the image data to extract the ruled line part, Ruled line pattern image data is generated in which a bit, a paper portion of the form 1 is represented by a white bit, and a background excluding the area of the form 1 is represented by a black bit. Here, details of generation of ruled line pattern image data are described in the cited document 1, and thus description thereof is omitted.

  As described above, when the ruled line pattern image generation unit 109 receives the complementary image data together with the generation instruction of the ruled line pattern image information, the ruled line pattern image generation unit 109 scans the complementary image data to extract the ruled line part, Generate ruled line pattern image data in which the paper portion of the form 1 is represented by white bits and the background excluding the area of the form 1 is represented by black bits.

  When the ruled line pattern image generation unit 109 generates ruled line pattern image data, the control unit 102 stores the generated ruled line pattern image data in the temporary storage unit 103 and instructs the ruled line feature information generation unit 110 to generate ruled line feature information. To do.

  The ruled line feature information generating unit 110 divides the form area of the ruled line pattern image data into an N × M matrix, obtains ruled line features indicating the characteristics of the ruled line pattern for each divided area, and these N × M ruled line features. It is a production | generation part which produces | generates the ruled line characteristic information which consists of. That is, when the ruled line feature information generation unit 110 receives an instruction to generate ruled line feature information, the ruled line feature information generation unit 110 divides the form area of the ruled line pattern image data held in the temporary storage unit 103 into preset N × M matrices. Ruled line features (ruled line shape, number of lines, length (coordinates), etc.) indicating the characteristic of the ruled line pattern for each region are obtained, and ruled line feature information including these N × M ruled line features is generated. Here, the details of the ruled line feature information generation are described in the cited document 1, and thus the description thereof is omitted.

  When the ruled line feature information generation unit 110 generates the ruled line feature information, the control unit 102 stores the ruled line feature information in the temporary storage unit 103.

  Then, after storing the ruled line feature information, the control unit 102 instructs the registered ruled line feature information management unit 112 to register the ruled line feature information when performing the form processing based on the registration of the form format.

  On the other hand, when the form processing based on the determination of the form format is performed, the control unit 102 instructs the form format determination unit 113 to determine the form format.

  The registered ruled line feature information DB 111 associates the ruled line feature information acquired from the image data of the various registration forms 1 with the registered ruled line feature corresponding to the form identification number input via the input unit 105 by the operator for identifying various forms. It is a database that is stored as information.

  The registered ruled line feature information management unit 112 is a management unit that manages registered ruled line feature information held in the registered ruled line feature information DB 111. That is, upon receiving an instruction to register ruled line feature information, the registered ruled line feature information management unit 112 registers registered ruled line feature information in which the form identification number held in the temporary storage unit 103 and the ruled line feature information are associated with each other. New registration is made in the information DB 111.

  When the registered ruled line feature information management unit 112 newly registers the registered ruled line feature information, the control unit 102 executes a memory program (not shown) to notify the operator that registration of the ruled line feature information of the form identification number has been completed. A ruled line feature information registration completion notification screen is displayed on a display provided in the display unit 104.

  Then, when the operator refers to the ruled line feature information registration completion notification screen displayed on the display unit 104 of the form processing apparatus 100, the operator grasps that registration of the form format of a certain form identification number has been completed.

  The form format determination unit 113 collates the ruled line feature information generated by the ruled line feature information generation unit 110 with the registered ruled line feature information held in the registered ruled line feature information DB 111, and the matching rate is equal to or higher than a preset threshold value. It is a determination unit that outputs a form identification number of registered ruled line feature information as a determination result. In other words, when the form format determination unit 113 receives an instruction to determine the form format, the form format determination unit 113 compares the ruled line feature information held in the temporary storage unit 103 with the registered ruled line feature information held in the registered ruled line feature information DB 111 to match. A form identification number of registered ruled line feature information whose rate is equal to or higher than a preset threshold is output as a determination result. Here, details of the collation of ruled line feature information are described in the cited document 1, and thus the description thereof is omitted.

  On the other hand, the form format determination unit 113 outputs a determination result indicating that identification is impossible when the matching rate of the ruled line feature information and all the registered ruled line feature information held in the registered ruled line feature information DB 111 is smaller than the threshold.

  When the form format determination unit 113 outputs a determination result indicating the form identification number, the control unit 102 executes a program in a memory (not shown) and notifies the operator of the form identification number as a result of the form format determination. A number notification screen is displayed on a display provided in the display unit 104.

  The operator grasps the form format of the identification form 1 included in the image data displayed on the display unit 104 by referring to the form identification number notification screen displayed on the display unit 104 of the form processing apparatus 100.

  On the other hand, when the form format determination unit 113 outputs a determination result indicating that authentication is not possible, the control unit 102 executes a memory program (not shown) and the operator cannot authenticate the form 1 as the determination result of the form format. Is displayed on a display provided in the display unit 104.

  The operator cannot recognize the form format of the form 1 included in the image data displayed on the display unit 104 by referring to the form format authentication impossible notification screen displayed on the display unit 104 of the form processing apparatus 100. To figure out.

<Operation of Example>
Next, the operation of the embodiment of the form processing apparatus 100 of the present invention will be described.

  First, the operation in the case of performing registration processing in the form format based on the image data of the registration form 1 will be described with reference to the flowcharts of FIGS.

  When an operator operating the form processing apparatus 100 instructs to read the image data of the registration form 1 on which only the ruled lines set in the image reading apparatus 200 are printed via the keyboard provided in the input unit 105, the control unit 102 An image request signal is generated, and the generated image request signal is transmitted to the image reading apparatus 200.

  When receiving an image request signal from the form processing apparatus 100, the image reading apparatus 200 optically scans a registration form 1 set in a reading unit (not shown) of the apparatus, and the ruled line portion of the form 1 has a black bit. Image data including a quantized black-and-white binary electric signal in which the paper portion of the form 1 is represented by white bits is generated. The image data generated by the image reading apparatus 200 is transmitted to the form processing apparatus 100 under the control of a control unit (not shown).

  When the control unit 102 of the form processing apparatus 100 acquires the image data via the communication unit 101, the control unit 102 stores the acquired image data of the registration form 1 in the image data storage unit 106 (step S101). Then, when the image data is stored, the control unit 102 executes a control program in a memory (not shown), and displays an image data display screen for allowing the operator to refer to the image data on a display provided in the display unit 104.

  When an operator who operates the form processing apparatus 100 instructs the registration of the form format to the image data of the registration form 1 displayed on the image data display screen via the keyboard provided in the input unit 105, the control unit 102 Then, a memory control program (not shown) is executed, and a form identification number input instruction screen for allowing the operator to input a form identification number for identifying the form 1 is displayed on a display provided in the display unit 104.

  The operator then refers to the form identification number input instruction screen displayed on the display unit 104 of the form processing apparatus 100 and inputs the form identification number for identifying the form 1 from the keyboard provided in the input unit 105. When the “registration” button, for example, on the identification number input instruction screen is pressed (step S102), the control unit 102 stores the acquired form identification number in the temporary storage unit 103 and the protrusion determination unit 107 determines whether the image data protrudes. Instruct. In this embodiment, the operator inputs the form identification number for identifying the form 1 at the time of registration via the input unit 105. However, a form identification number (form ID etc.) is previously stored in the registration form 1 itself. A form identification unit (not shown) that is provided may automatically identify the form 1.

  When the protrusion determination unit 107 receives an instruction for determination of protrusion, it scans the image data held in the temporary storage unit 103, and if a white pixel exists at the image end of the image data as shown in FIG. 3 (step S103). , It is determined that the protrusion is present (step S104). When the protrusion determination unit 107 determines that the protrusion is present, the control unit 102 instructs the image complement processing unit 108 to perform image complement processing.

  On the other hand, the protrusion determination unit 107 determines that there is no protrusion when there is no white pixel at the image end of the image data. When the protrusion determination unit 107 determines that there is no protrusion (step S105), the control unit 102 instructs the ruled line pattern image generation unit 109 to generate a ruled line pattern image and transfers the image data held in the image data storage unit 106. .

  Upon receiving an instruction to generate ruled line pattern image information and image data, the ruled line pattern image generation unit 109 scans the image data to extract a ruled line part, and generates ruled line pattern image data (step S106).

  Upon receiving an instruction for image complement processing, the image complement processing unit 108 first scans the image data held in the temporary storage unit 103, and the four vertices “LT (LTx LTx) constituting the mid-form area as shown in FIG. , LTy), LB (LBx, LBy), RT (RTx, RTy), and RB (RBx, RBy) ”, and since a white pixel exists at the right end of the image data image, the protruding direction = right is acquired. (Step S107).

  Next, the image complementation processing unit 108 calculates the size in the length direction of the mid-form of the image data, and sets the A4 horizontal size (210 mm) set in advance and the size in the length direction of the mid-form area. Due to this difference, 210 mm, for example, is 210 × 240 / 25.4≈1984 dots on an image with a resolution of 240 dpi. Therefore, if the size in the length direction of the intermediate area of the form is, for example, 1500 dots, the length of the complementary area The size of the direction is calculated to be 1984 dots-1500 dots = 484 dots (step S108).

  Then, when the image complement processing unit 108 calculates the size (484 dots) of the length dimension of the complement region, the coordinates of four vertices “RT (RTx, RTy), RB (RBx, RBy), R as shown in FIG. A complementary region constituted by “T (RTx + 484, RTy), R′B (RBx + 484, RBy)” is generated (step S109). Here, the complement region is entirely composed of white pixels.

  When the complement region is generated, the image complement processing unit 108 generates complement image data as shown in FIG. 6 in which the complement region is combined with the mid-form region of the image data (step S110). Here, in the complementary image data, the background part excluding the form area is composed entirely of black pixels.

  When the image complement processing unit 108 generates complement image data, the control unit 102 stores the complement image data in the temporary storage unit 103. Then, after storing the complementary image data, the control unit 102 instructs the ruled line pattern image generation unit 109 to generate a ruled line pattern image and transfers the complementary image data.

  Upon receiving an instruction to generate ruled line pattern image information and complementary image data, the ruled line pattern image generation unit 109 scans the complementary image data to extract a ruled line part, and generates ruled line pattern image data (step S111).

  When the ruled line pattern image generation unit 109 generates ruled line pattern image data, the control unit 102 stores the generated ruled line pattern image data in the temporary storage unit 103. After storing the ruled line pattern image data, the control unit 102 instructs the ruled line feature information generating unit 110 to generate ruled line feature information and transfers the ruled line pattern image data.

  Upon receiving the ruled line feature information generation instruction and the ruled line pattern image data, the ruled line feature information generating unit 110 divides the form area of the ruled line pattern image data into a preset N × M matrix, and the ruled line for each divided area. Ruled line features (pattern shape, number, length (coordinates), etc.) indicating pattern characteristics are obtained, and ruled line feature information including these N × M ruled line features is generated (step S112).

  When the ruled line feature information generation unit 110 generates the ruled line feature information, the control unit 102 stores the ruled line feature information in the temporary storage unit 103.

  Then, after storing the ruled line feature information, the control unit 102 instructs the registered ruled line feature information management unit 112 to register the ruled line feature information when performing the form processing based on the registration of the form format.

  Upon receiving an instruction to register ruled line feature information, the registered ruled line feature information management unit 112 registers registered ruled line feature information in which the form identification number held in the temporary storage unit 103 and the ruled line feature information are associated with each other. Is newly registered (step S113).

  When the registered ruled line feature information management unit 112 newly registers the registered ruled line feature information, the control unit 102 executes a memory program (not shown) to notify the operator that registration of the ruled line feature information of the form identification number has been completed. For this purpose, a ruled line feature information registration completion notification screen is displayed on a display provided in the display unit 104 (step S114).

  Then, when the operator refers to the ruled line feature information registration completion notification screen displayed on the display unit 104 of the form processing apparatus 100, the operator grasps that the registration of the ruled line feature information of a certain form identification number has been completed.

  Next, the operation in the case of performing a form format recognition process based on the image data of the identification form 1 will be described with reference to the flowcharts of FIGS.

  The operation in step S201 in the embodiment is the same as the operation in step S101 in the embodiment.

  When an operator operating the form processing apparatus 100 instructs the image data of the identification form 1 displayed on the image data display screen on the display unit 104 to determine the form format via the keyboard provided in the input unit 105 ( In step S202), the control unit 102 instructs the protrusion determination unit 107 to determine whether the image data protrudes.

  The operations in steps S203 to S212 in the embodiment are the same as the operations in steps S103 to S112 in the embodiment.

  The control unit 102 of the form processing apparatus 100 instructs the form format determination unit 113 to determine the form format when performing the form processing based on the determination of the form format.

  When receiving the form format determination instruction, the form format determination unit 113 collates the ruled line feature information held in the temporary storage unit 103 with the registered ruled line feature information held in the registered ruled line feature information DB 111 (step S213). The form format determination unit 113 collates the ruled line feature information with the registered ruled line feature information, and if there is registered ruled line feature information whose collation matching rate is equal to or greater than a preset threshold value (step S214), the registered ruled line feature information The form identification number of information is output as a determination result.

  When the form format determination unit 113 outputs a determination result indicating the form identification number, the control unit 102 executes a program in a memory (not shown) and notifies the operator of the form identification number as a result of the form format determination. The number notification screen is displayed on the display provided in the display unit 104 (step S215).

  The operator grasps the form format of the identification form 1 included in the image data displayed on the display unit 104 by referring to the form identification number notification screen displayed on the display unit 104 of the form processing apparatus 100.

  On the other hand, the form format determination unit 113 outputs a determination result indicating that identification is impossible when the matching rate of the ruled line feature information and all the registered ruled line feature information held in the registered ruled line feature information DB 111 is smaller than the threshold.

  When the form format determination unit 113 outputs a determination result indicating that authentication is not possible, the control unit 102 executes a memory program (not shown) and notifies the operator that the form 1 is not authenticated as the determination result of the form format. A form-form-authentication notification screen is displayed on the display provided in the display unit 104 (step S216).

  In the present exemplary embodiment, the form processing apparatus 100 defines a pre-set rule in the image complement processing unit 108 for a mid-form area included in image data that does not include the entire form 1 read by the image reading apparatus 200. Although the complement processing is performed so as to be the size area, the operator who operates the form processing apparatus 100 designates the area where the feature of the ruled line should be recognized through the input unit 105 as shown in FIG. You may make it the structure which performs a complementation process with respect to the area | region based. With the configuration described above, the ruled line pattern image generation unit 109 can extract the ruled line pattern only for the area to be recognized, thereby improving the form format identification performance of the form processing apparatus 100.

  In this embodiment, the form processing apparatus 100 is executed from the acquisition of the image data of the form 1 for registration from the image reading apparatus 200 in order to register the ruled line feature information in the registered ruled line feature information DB 111. After the ruled line feature information is generated by the feature information generation unit 110, the ruled line feature information is stored in a storage area of the apparatus main body, and then only the ruled line feature information stored in the storage area is read and the ruled line feature information is registered. It may be configured to be registered in the ruled line feature information DB 111.

  Furthermore, in this embodiment, as a determination of whether or not the entire form 1 is included in the image data, the protrusion determination unit 107 of the form processing apparatus 100 determines whether or not a white pixel exists at the image edge of the image data. Based on this, the process for determining the presence or absence of protrusion is performed. However, when there is a white pixel that is equal to or greater than a preset threshold in the image data, it may be determined that the protrusion is present.

  Then, instead of the above-described configuration of the protrusion determination unit 107 of the form processing apparatus 100 according to the present embodiment, an operator operating the form processing apparatus 100 refers to the image data displayed on the display provided in the display unit 104 and visually protrudes. It may be configured such that the determination is performed and the determination result is input via the input unit 105.

  In the above-described embodiment, the case where the form processing apparatus according to the embodiment of the present invention is introduced to a financial institution has been described as an example. However, the present invention recognizes the case where image data of a form having ruled lines is identified based on the characteristics of the ruled lines. Therefore, it is not limited to use in a financial institution.
