Description

  The present invention relates to an electronic writing processing program for converting contents written by an operator into electronic data.

  2. Description of the Related Art Conventionally, there has been known an electronic writing apparatus that converts contents written by an operator into electronic data (see, for example, Patent Document 1). In this prior art, when a user performs a desired description using a writing tool (electronic pen) on a writing medium (paper medium) in an electronic writing device (reading device), a plurality of writing tools that move by a writing operation are used. Stroke data including position data is generated and transmitted to the operation terminal (PC). The operation terminal receives the stroke data and stores the received stroke data.

JP 2014- 211754 A

  Here, for example, the operator uses a correction tool (a so-called correction pen or correction tape) as the writing tool, so that a character or image already described on the writing medium is painted in white, or a coloring tool (a so-called fluorescent tool) is used as the writing tool. In some cases, these characters or images are colored by using a pen (hereinafter, these are collectively referred to as “overcoating” where appropriate). Unlike normal pens or the like, these correction tools and coloring tools often have a writing posture that is greatly inclined with respect to the writing medium. As a result, on the actual writing medium, the electronic data obtained as described above is obtained even though the corrective / coloring tool is correctly overcoated so as to overlap the character or image to be overcoated. In the data, there is a possibility that the stroke data of the overcoat portion by the correction tool / coloring tool is shifted (not correctly superimposed) with respect to the stroke data of the character or image to be overcoated.

  An object of the present invention is to provide an electronic writing processing program that can perform correct electronic data reflecting the intention of overcoating by an operator and can improve convenience.

  In order to achieve the above object, the electronic writing processing program of the present invention includes a plurality of position data of the writing tool accompanying movement of the writing tool with respect to the writing medium, and stroke data corresponding to the writing on the writing medium by the writing tool. The operation procedure of the operation terminal connected to the electronic writing device that transmits information by communication, the receiving procedure for receiving the stroke data from the electronic writing device, and the stroke data received in the receiving procedure. A storage procedure to be stored; a detection procedure for detecting a topcoat image written on the writing medium based on the stroke data stored in the storage procedure; and a case in which the topcoat image is detected in the detection procedure Among the stroke data stored in the storage procedure, the first stroke data to be overcoated The determination procedure to be determined and the second stroke data stored in the storing procedure corresponding to the top-painted image are shifted in correspondence with the position of the first stroke data and superimposed on the first stroke data. The first shift processing procedure is executed.

  In the present invention, the contents written by the operator using the writing instrument can be converted into electronic data. That is, when an operator performs a desired description using a writing tool on a writing medium made of a predetermined paper medium or the like in an electronic writing device, stroke data including a plurality of position data of the writing tool that is moved by the writing operation is obtained. It is generated and transmitted to the operation terminal. The operation terminal receives the stroke data (reception procedure) and stores the stroke data in an appropriate storage unit (storage procedure) when the electronic writing processing program is executed in the calculation unit.

  Here, for example, the operator uses a correction tool (a so-called correction pen or correction tape) as the writing tool, so that a character or image already described on the writing medium is painted in white, or a coloring tool (a so-called fluorescent tool) is used as the writing tool. In some cases, these characters or images are colored by using a pen (hereinafter, these are collectively referred to as “overcoating” where appropriate). Unlike normal pens or the like, these correction tools and coloring tools often have a writing posture that is greatly inclined with respect to the writing medium. As a result, on the actual writing medium, the electronic data obtained as described above is obtained even though the corrective / coloring tool is correctly overcoated so as to overlap the character or image to be overcoated. In the data, there is a possibility that the stroke data of the overcoat portion by the correction tool / coloring tool is shifted (not correctly superimposed) with respect to the stroke data of the character or image to be overcoated.

  In the present invention, in order to deal with the above, first, based on the stored stroke data, an overprint image (for example, a white solid-coated belt-shaped region by the correction tool or the coloring tool described above) written on the writing medium. Is detected (detection procedure). When the top coating image is detected, stroke data (first stroke data) to be subjected to top coating processing is determined from the stored stroke data (determination procedure). At this time, for the reasons described above, in the electronic data, there is a positional deviation between the stroke data (second stroke data) corresponding to the overpainting image and the first stroke data. Therefore, in the first shift processing procedure, the second stroke data corresponding to the top coating image is shifted in correspondence with the position of the first stroke data, and is superimposed on the first stroke data.

  As a result, the above-described positional deviation is eliminated, and the second stroke data of the overpainting image and the first stroke data of the character / graphic image to be overcoated can be superimposed on the electronic data. As a result, it is possible to perform correct electronic data reflecting the intention of the operator to correct by the white paint or the transparent coloring, so that the convenience can be improved.

  According to the present invention, correct electronic data reflecting the intention of overcoating by the operator can be performed, and convenience can be improved.

The electronic pen 3 is a so-called electromagnetic induction pen, and includes a metal core 37, a detection switch 33, a button-type battery 34, a coil 35, and a substrate 36 provided inside the tip. Prepare. The core 37 includes a pen tip 31 that protrudes to the outside and an ink storage portion 32. Ink is stored in the ink storage portion 32, and the ink is supplied to the pen tip 31. Thereby, the operator can visually describe a desired character or image (hereinafter abbreviated as “character etc.” as appropriate) on the paper medium 70 using the electronic pen 3. In the following description, in the electronic pen 3, the direction in which the pen tip 31 is provided is referred to as the front end direction, and the direction opposite to the front end direction is referred to as the rear end direction.

  The CPU 401 is electrically connected to the ROM 402, RAM 403, memory 404, operation unit 405, display unit 406, and communication control unit 407.

  The ROM 402 stores various programs that are executed by the CPU 401 to control the operation terminal 4.

<Flow of electronic data conversion>
6A to 6C for an example of the flow of converting the contents written on the paper medium 70 on the placement unit 24 into electronic data by the operator using the electronic writing instrument W in the basic configuration. However, it will be explained.

  FIG. 6A shows an example where the operator has written desired characters on the paper medium 70 using the electronic pen 3.

  In the example shown in FIG. 6A, the operator uses the electronic pen 3 to write a group of character strings “1, Ah” in the upper left of the paper medium 70 and write a group of character strings “ 2, ABC "is written in the left horizontal writing. Note that the left horizontal writing is a writing method in which the writing direction is a horizontal direction from left to right. The magnetic field generated from the coil 35 of the electronic pen 3 when performing the above description is detected by the coordinate detection unit 25. Then, the coordinate data corresponding to each position of the electronic pen 3 when performing the above description is associated with the writing tool ID “ID1” and the time data, and is sequentially stored in the coordinate data storage area 2041 as writing related data. The

  FIG. 6B shows an example in which the operator uses the electronic correction tape 5 to coat characters and the like already written on the paper medium 70 with white.

  In the example shown in FIG. 6B, the operator uses the electronic correction tape 5 and the group of character strings “1, say” described in the upper part of the paper medium 70 in the state shown in FIG. The correction area WE is written in the left horizontal writing in the portion on the paper medium 70 corresponding to the latter half character string “A”, and the character string “A” is overcoated with white. The magnetic field generated from the coil 53 of the electronic correction tape 5 when performing this description is detected by the coordinate detection unit 25. Then, the coordinate data corresponding to each position of the electronic correction tape 5 at the time of the above description is associated with the writing tool ID “ID2” and the time data, and sequentially stored in the coordinate data storage area 2041 as writing related data. Is done.

  FIG. 6C shows an example in which the operator uses the electronic pen 3 to write desired characters or the like on the white topcoat portion of the correction area WE on the paper medium 70.

  In the example shown in FIG. 6C, the operator uses the electronic pen 3 to write the character string “Kakiku” on the white top coat portion on the paper medium 70 in the state shown in FIG. It is described. The magnetic field generated from the coil 35 of the electronic pen 3 when performing this description is detected by the coordinate detection unit 25. Then, the coordinate data corresponding to each position of the electronic pen 3 when performing the above description is associated with the writing tool ID “ID1” and the time data, and is sequentially stored in the coordinate data storage area 2041 as writing related data. The

  When the operator performs a predetermined operation (for example, checking a check column provided in an appropriate part on the paper medium 70) in the electronic writing apparatus 2, a plurality of writing-related items stored in the coordinate data storage area 2041 are stored. Based on the data, stroke data corresponding to the contents written on the paper medium 70 by the electronic pen 3 and the electronic correction tape 5 is generated and stored in the RAM 203. Thereafter, the stroke data stored in the RAM 203 is transmitted to the operation terminal 4. As a result, the operation terminal 4 receives the stroke data and stores it in the RAM 403.

  Here, in the electronic pen 3, the coil 35 is disposed in a portion recessed from the pen tip 31 due to its structure, and in the electronic correction tape 5, the coil 53 is disposed in a portion recessed from the head 51 due to its structure. Has been placed.

  For example, when the operator writes characters or the like on the paper medium 70 using the electronic pen 3 as in the example of FIGS. In many cases, it is used without being inclined so much that the value of the coordinate data detected by the coordinate detection unit 25 is not shifted from the actual coordinates on the paper medium 70.

  On the other hand, for example, when the operator uses the electronic correction tape 5 to coat characters and the like already written on the paper medium 70 in white as in the example of FIG. The coordinate data detected by the coordinate detection unit 25 may deviate from the actual coordinates on the paper medium 70 in many cases. As a result, on the actual paper medium 70, although the correction area WE is correctly written by the electronic correction tape 5 so as to overlap the character to be corrected and the white overcoat is performed, on the electronic data, There is a possibility that the position of the stroke data in the correction area WE may be shifted (not correctly superimposed) with respect to the position of the stroke data corresponding to the character to be corrected.

  FIG. 7 shows an example in which image data is converted into a state where the position of the stroke data in the correction area WE is shifted from the position of the stroke data such as characters to be corrected.

  In the upper part of FIG. 7, each stroke data generated corresponding to the description on the paper medium 70 in the state shown in FIG. 6C is shown between a plurality of positions of each stroke data for convenience of explanation. Each position of the stroke data in the correction area WE is indicated by “◯”. Note that the band-like area indicated by the symbol “WE ′” is a state in which lines are drawn between a plurality of positions of the stroke data of the correction area WE. In the example shown in the upper part of FIG. 7, the position of the stroke data in the correction area WE is deviated (not correctly superimposed) from the position of the stroke data of the character string “A” for the above reason. In this state, when image data corresponding to the description content on the paper medium 70 in the state shown in FIG. 6C is generated, the stroke of the character string “That” depends on the position of the stroke data in the correction area WE. Since all of the data positions are not superimposed, the portion of the position where the data is not superimposed remains without being erased. In this case, as in the example shown in the lower part of FIG. 7, on the generated image data, the white overcoat image WE ″ generated based on the stroke data of the correction area WE is shifted to a position shifted from the original position. For this reason, a part of the character string “Ah” has been imaged.

<Features of this embodiment>
The feature of the present embodiment is that correct electronic data is created that reflects the operator's intention of correction by white overcoating. The details will be described below.

  In the present embodiment, when stroke data is received and stored in the RAM 403 in the operation terminal 4 as described above, the stroke data is sequentially acquired from the RAM 403, and a line is formed between a plurality of positions of the acquired stroke data. Rendered and imaged.

  At this time, if the acquired stroke data is the stroke data of the correction area WE, based on the stroke data of the correction area WE, the entry direction of the correction area WE by the electronic correction tape 5 (hereinafter referred to as “correction direction” as appropriate). Is determined). For example, in a plurality of coordinate data related to the stroke data of the correction area WE, if the change amount of the X coordinate value is larger than the change amount of the Y coordinate value and the change of the X coordinate value tends to increase, the correction direction is “ If the change amount of the X coordinate value is larger than the change amount of the Y coordinate value and the change of the X coordinate value tends to decrease, the correction direction is “from right to left”. If the change amount of the Y coordinate value is larger than the change amount of the X coordinate value and the change of the Y coordinate value tends to increase, the correction direction is “vertical direction from top to bottom”. If the change amount of the Y coordinate value is larger than the change amount of the X coordinate value and the change of the Y coordinate value is decreasing, the correction direction is determined as “vertical direction from bottom to top”. .

  Thereafter, a calculation process is performed for calculating a shift amount for shifting the stroke data of the correction area WE in correspondence with the position of stroke data to be subjected to an overcoating process described later. Hereinafter, the content of this calculation process will be described with reference to FIG.

  FIG. 8 shows the stroke data acquired until the calculation process is performed among the stroke data generated corresponding to the description on the paper medium 70 in the state shown in FIG. 7 is shown in the same manner as the upper part of FIG. In the example illustrated in FIG. 8, the correction direction is determined to be a lateral direction from left to right.

  In FIG. 8, in the calculation process, first, a known appropriate character recognition process (for example, OCR process) is performed on what has been drawn and imaged so far, and a coordinate range 60 of each character or the like that has been character-recognized is obtained. Detected. Then, a search range 61 corresponding to the correction direction is set, and whether or not a predetermined position corresponding to the correction direction in the coordinate range 60 is included in the search range 61 for each character or the like recognized above. If it is determined and there is a character or the like whose predetermined position is included in the search range 61, the shift amount is calculated.

  For example, when the correction direction is a horizontal direction from left to right as in the example shown in FIG. 8, the X coordinate range related to the search range 61 is a plurality of coordinate data related to the stroke data of the correction region WE. From the value obtained by subtracting a predetermined value from the X coordinate value Xa of the position (leftmost position) Ta indicated by the coordinate data with the earliest time indicated by the associated time data, the predetermined value is added to the X coordinate value Xa of the position Ta. The range is set up to the added value. Further, the Y coordinate range related to the search range 61 is obtained by subtracting a value of ½ of the line thickness w previously associated with the writing instrument ID associated with the coordinate data from the Y coordinate value Ya of the position Ta. The value is set to a range from the value obtained by adding the half value of the thickness w and the predetermined value to the Y coordinate value Ya of the position Ta. Thereafter, it is determined whether or not the position of the lower left end in the coordinate range 60 is included in the search range 61 for each character that has been recognized, and the position of the lower left end is within the search range 61. When there is a character or the like included (in the example shown in FIG. 8, the position Tb of the lower left end in the coordinate range 60 of the character “A” is included in the search range 61), the shift amount is calculated. Done. That is, the shift amount of the X coordinate is related to the X coordinate value of the position of the left lower end portion related to the character or the like whose position of the lower left end portion is included in the search range 61 (in the example shown in FIG. It is calculated by subtracting the X coordinate value Xa of the position Ta from the X coordinate value Xb of the position Tb of the lower left end. Further, the shift amount of the Y coordinate is related to the Y coordinate value of the position of the left lower end portion relating to the character or the like whose position of the lower left end portion is included in the search range 61 (in the example shown in FIG. It is calculated by subtracting the value obtained by adding the Y coordinate value Ya of the position Ta and the half value of the thickness w from the X coordinate value Yb of the position Tb of the lower left end.

  Further, for example, when the correction direction is the horizontal direction from right to left, the X coordinate range related to the search range 61 is the time data associated with the coordinate data among the plurality of coordinate data related to the stroke data of the correction area WE. Set to a range from the value obtained by subtracting a predetermined value from the X coordinate value of the position (rightmost position) indicated by the coordinate data with the earliest time to the value obtained by adding the predetermined value to the X coordinate value of the rightmost position Is done. Further, the Y coordinate range related to the search range 61 is obtained by subtracting a value of ½ of the line thickness w previously associated with the writing instrument ID associated with the coordinate data from the Y coordinate value of the rightmost position. The value is set to a range from the value obtained by adding the half value of the thickness w and the predetermined value to the Y coordinate value Ya of the rightmost position. Thereafter, it is determined whether or not the position of the lower right corner in the coordinate range 60 is included in the search range 61 for each character that has been recognized, and the position of the lower right corner is within the search range 61. When there is a character or the like included, the shift amount is calculated. That is, the shift amount of the X coordinate is obtained by subtracting the X coordinate value of the rightmost position from the X coordinate value of the position of the right lower end portion of the character or the like whose position of the right lower end portion is included in the search range 61. It is calculated by. Further, the shift amount of the Y coordinate is calculated based on the Y coordinate value of the rightmost position and the thick value from the Y coordinate value of the position of the right lower end part of the character or the like whose position of the right lower end part is included in the search range 61. It is calculated by subtracting a value obtained by adding a half value of the length w.

  Further, for example, when the correction direction is a vertical direction from top to bottom, the X coordinate range related to the search range 61 is the time data associated with the coordinate data among the plurality of coordinate data related to the stroke data of the correction region WE. From the X coordinate value of the position (top position) indicated by the coordinate data with the earliest time indicated, a value 1/2 and a predetermined value of the line thickness w associated in advance with the writing tool ID associated with the coordinate data are obtained. The range is set from the subtracted value to the value obtained by adding the half value of the thickness w to the X coordinate value of the uppermost position. Further, the Y coordinate range related to the search range 61 is a range from a value obtained by subtracting the predetermined value from the Y coordinate value at the uppermost position to a value obtained by adding the predetermined value to the Y coordinate value Ya at the uppermost position. Is set. Thereafter, it is determined whether or not the position of the upper left end in the coordinate range 60 is included in the search range 61 for each character or the like that has been recognized, and the character or the like in which the position is included in the search range 61 If there is a shift, the shift amount is calculated. That is, the shift amount of the X coordinate is calculated from the X coordinate value of the position of the upper left end portion of the character or the like whose upper left end position is included in the search range 61 to the thickness from the X coordinate value of the uppermost position. It is calculated by subtracting a value obtained by subtracting a value half of w. Further, the amount of shift of the Y coordinate is obtained by subtracting the Y coordinate value of the uppermost position from the Y coordinate value of the position of the upper left end portion of the character or the like whose position of the upper left end portion is included in the search range 61. Is calculated by

  Further, for example, when the correction direction is a vertical direction from bottom to top, the X coordinate range related to the search range 61 is the time data associated with the coordinate data among the plurality of coordinate data related to the stroke data of the correction region WE. A value 1/2 and a predetermined value of the thickness w of the line associated in advance with the writing tool ID associated with the coordinate data from the X coordinate value indicated by the coordinate data with the earliest time indicated (the lowest position). Is set to a range from a value obtained by subtracting ½ to a value obtained by adding a value of ½ of the thickness w to the X coordinate value of the lowest position. Further, the Y coordinate range related to the search range 61 is from a value obtained by subtracting the predetermined value from the Y coordinate value at the lowest position to a value obtained by adding the predetermined value to the Y coordinate value Ya at the lowest position. Set to range. Thereafter, it is determined whether or not the position of the lower left end in the coordinate range 60 is included in the search range 61 for each character that has been recognized, and the character or the like whose position is included in the search range 61. If there is a shift, the shift amount is calculated. That is, the shift amount of the X coordinate is calculated from the X coordinate value of the position of the lower left end portion of the character or the like whose position of the lower left end portion is included in the search range 61 to the thickness from the X coordinate value of the uppermost position. It is calculated by subtracting a value obtained by subtracting a value half of w. Further, the amount of shift of the Y coordinate is obtained by subtracting the Y coordinate value of the uppermost position from the Y coordinate value of the position of the lower left end portion of the character or the like whose position of the lower left end portion is included in the search range 61. Is calculated by

  When the shift amount is calculated as described above, among the stroke data acquired up to this point, the position is separated from the position of the stroke data in the correction area WE by the calculated shift amount. Stroke data of a certain character or the like is determined as stroke data (corresponding to the first stroke data) to be overcoated corresponding to a white overcoated portion by entering the correction area WE on the paper medium 70. Then, the stroke data of the correction area WE is shifted with the calculated shift amount. Hereinafter, the contents of this shift processing will be described with reference to FIG.

  In FIG. 9, in the shift process, each position of the stroke data in the correction area WE is shifted by adding the shift amount to the value indicated by each coordinate data related to the stroke data in the correction area WE. As a result, the position of the stroke data in the correction area WE is superimposed on the position of the stroke data to be overpainted (in the example of FIG. 9, the stroke data of the character example “A”).

  When the shift process is performed as described above, the stroke data that is the target of the overcoating process in which the position is superimposed by the stroke data of the correction area WE subjected to the shift process is erased. In this erasing process, based on the stroke data to be overcoated in the overlapped part so that an image based on the stroke data to be overcoated in the part where the position is superimposed by the stroke data of the correction area WE is not displayed. What is drawn and imaged is hidden.

<Control flow>
Next, a control procedure executed by the CPU 401 of the operation terminal 4 based on the electronic writing processing program stored in the memory 404 in order to realize the above contents will be described with reference to FIG.

  In FIG. 10, the process shown in this flowchart is started when the power of the operation terminal 4 is turned on, for example.

  First, in step S <b> 10, the CPU 401 is generated based on stroke data (coordinate data, writing tool ID, and a plurality of writing related data including time data) corresponding to the description on the paper medium 70 transmitted from the electronic writing apparatus 2. Data) is received via the communication control unit 407. The procedure of step S10 corresponds to the receiving procedure described in each claim.

  Thereafter, in step S20, the CPU 401 stores the stroke data received in step S10 in the RAM 403. The procedure of step S20 corresponds to the storage procedure described in each claim.

  In step S30, the CPU 401 sequentially acquires the stroke data stored in the RAM 403 in step S20 from the RAM 403 in time series.

  Thereafter, in step S40, the CPU 401 determines whether stroke data has been acquired in step S30. If the stroke data can be acquired in step S30, the determination in step S40 is satisfied, and the process proceeds to step S50.

  In step S50, the CPU 401 detects the writing instrument ID related to the stroke data acquired in step S30. When the writing tool ID “ID1” is detected in step S50 (when a character or the like written on the paper medium 70 is detected by the electronic pen 3), that is, the stroke data acquired in step S30 is a character or the like. If it is stroke data, the process proceeds to step S60.

  In step S60, the CPU 401 draws a line with a thickness of a line previously associated with the writing tool ID “ID1” between a plurality of positions indicated by a plurality of coordinate data related to the stroke data acquired in step S30. And image it. Thereafter, the process returns to step S30 and the same procedure is repeated.

  On the other hand, when the writing instrument ID “ID2” is detected in step S50 (when the correction area WE written in the paper medium 70 is detected by the electronic correction tape 5), that is, the stroke acquired in step S30. If the data is the stroke data of the correction area WE, the process proceeds to step S70. The procedure of step S50 corresponds to the detection procedure described in each claim.

  In step S70, the CPU 401 determines the correction direction based on the stroke data of the correction area WE acquired in step S30.

  In step S80, the CPU 401 performs character recognition processing on the image drawn and imaged in step S60 based on the stroke data acquired in step S30 up to this point, and each character that has been character-recognized. The coordinate range 60 is detected, and the information is stored in the RAM 403.

  Thereafter, in step S90, the CPU 401 sets the search range 61 according to the correction direction determined in step S70.

  In step S <b> 100, the CPU 401 sequentially acquires information on the coordinate range 60 of each character and the like recognized in step S <b> 80 and stored in the RAM 403 from the RAM 403.

  Thereafter, in step S110, the CPU 401 determines whether or not the information of the coordinate range 60 has been acquired in step S100. When the information of the coordinate range 60 can be acquired in step S100, the determination in step S110 is satisfied, and the process proceeds to step S120.

  In step S120, the CPU 401 determines that the predetermined position corresponding to the correction direction determined in step S70 in the coordinate range 60 for the character or the like whose information in the coordinate range 60 is acquired in step S100 is the step S90. It is determined whether or not it is included in the search range 61 set in. If the predetermined position of the character or the like is not included in the search range 61, the determination in step S120 is not satisfied, and the same procedure is repeated by returning to step S100. On the other hand, when the predetermined position of the character or the like is included in the search range 61, the determination in step S120 is satisfied, and the process proceeds to step S130.

  In step S130, the CPU 401 determines that the stroke data of the correction area WE acquired in step S30, the correction direction determined in step S80, and the predetermined position is included in the search range 61 in step S120. The shift amount is calculated based on the predetermined range related to the character or the like.

  Then, in step S140, the CPU 401 determines a position separated from the position of the stroke data in the correction area WE by the shift amount calculated in step S130 among the stroke data acquired in step S30 up to this point. Is determined as stroke data to be overcoated. The procedure of step S140 corresponds to the determination procedure described in each claim.

  Thereafter, in step S150, the CPU 401 shifts the stroke data of the correction area WE acquired in step S30 with the shift amount calculated in step S130, and determines the position of the stroke data in the correction area WE as described above. It is superimposed on the position of the stroke data to be overcoated in step S140. The procedure of step S150 corresponds to the first shift processing procedure described in each claim.

  In step S160, the CPU 401 does not display an image based on the stroke data to be overcoated in the portion whose position is superimposed by the stroke data of the correction area WE shifted in step S150 in step S180 described later. In addition, an erasing process is performed to hide the image drawn and imaged in step S60 based on the stroke data to be overcoated in the superimposed portion. Note that the CPU 401 may perform the erasure process of hiding the stroke data as the top coating process target of the superimposed portion from the RAM 403 while making the above-mentioned non-display. The procedure of step S160 corresponds to the first erasure processing procedure described in each claim. Thereafter, the process returns to step S30 and the same procedure is repeated.

  When the same procedure is repeated from step S160 to step S30 as described above, the writing tool ID “ID2” is detected in step S50 for the other stroke data, and the correction direction determined in step S70 is the first. If it is the same as the correction direction determined in step S70, the CPU 401 skips steps S80 to S130, and in step S140, from the position of the stroke data in the other correction area WE, the previous step S130. The stroke data of characters and the like at positions separated by the shift amount calculated in step S3 is determined as stroke data to be overcoated, and in step S150, using the shift amount calculated in the previous step S130, Shift processing of stroke data of the correction area WE It may be.

  On the other hand, in step S110, if the information of coordinate range 60 could not be acquired in step S100, the information of coordinate range 60 such as all characters recognized in step S80 and stored in RAM 403 has already been acquired. However, it is considered that the predetermined position of any character or the like is not included in the search range 61, and the determination in step S110 is not satisfied, and the process proceeds to step S170.

  In step S170, the CPU 401 performs predetermined error processing, and then returns to step S30 and repeats the same procedure.

  On the other hand, if the stroke data cannot be acquired in step S30 in step S40, it is regarded that the stroke data stored in the RAM 403 has been acquired in step S20, and the determination in step S40 is not satisfied. The process moves to S180.

  In step S180, the CPU 401 displays the image generated at this time on the display unit 406. Thereafter, the processing shown in this flowchart is terminated.

<Effects of this embodiment>
As described above, in the present embodiment, as described above, on the actual paper medium 70, the electronic correction tape 5 correctly applies the white overcoat so as to overlap the character to be corrected. Regardless, on the electronic data, it corresponds to the possibility that the position of the stroke data of the white overcoat portion by the electronic correction tape 5 is shifted (not correctly superimposed) with respect to the position of the stroke data such as characters to be corrected. Therefore, based on the stroke data stored in the RAM 403, the correction area WE written on the paper medium 70 is detected by the electronic correction tape 5. When the correction area WE is detected, the stroke data to be overcoated among the stroke data stored in the RAM 403 is determined. At this time, for the reason described above, there is a positional shift between the stroke data of the correction area WE and the stroke data to be overcoated on the electronic data. Therefore, the position of the stroke data in the correction area WE is shifted in correspondence with the position of the stroke data to be overcoated, and is superimposed on the position of the stroke data to be overcoated.

  Thereby, the positional deviation is eliminated, and the position of the stroke data of the correction area WE and the position of the stroke data such as the character to be corrected can be superimposed on the electronic data. As a result, it is possible to perform correct electronic data reflecting the intention of correction by white overcoating by the operator, so that convenience can be improved.

  In the present embodiment, in particular, the image generated based on the stroke data that is the target of the top coating process in which the position is superimposed by the stroke data of the correction area WE subjected to the shift process is erased. As a result, when the operator uses the electronic correction tape 5 to apply characters or the like to be corrected (corresponding to the stroke data to be overcoated) in white, the intention is reflected on the electronic data. It is possible to prevent the image generated based on the stroke data to be subjected to the overcoating process corresponding to the shape from being deleted or displayed.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described.

(1) In the case where shift processing is performed by manual operation In the above-described embodiment, the case where automatic shift processing is performed using the calculated shift amount has been described. However, in addition to (or separately from) the above automatic shift processing, The shift process may be performed using a desired shift amount by manual operation. Below, the case where the said shift process is combined with the said automatic shift process is demonstrated. In this modification, the operation unit 405 includes a direction key (for example, an up key, a down key, a left key, a right key, etc.) that indicates a shift direction, and a shift amount corresponding to one operation of the direction key. Are associated in advance.

  Hereinafter, a control procedure executed by the CPU 401 of the operation terminal 4 based on the electronic writing process program in the present modification will be described with reference to FIG.

  In FIG. 11, steps S10 to S180 are the same as those in FIG. 10 described above. When the CPU 401 displays an image generated at this time on the display unit 406 in step S180, the process proceeds to step S200.

  In step S200, the CPU 401 shifts the stroke data of the correction area WE shifted in step S150 via the direction key by the operator or the position of the stroke data of the correction area WE via the operation unit 405. A confirmation operation for confirming is accepted. The procedure of step S200 corresponds to the shift acceptance procedure described in each claim.

  Thereafter, in step S210, the CPU 401 determines the content of the operation received in step S200. If the operation received in step S200 is the shift operation, the process proceeds to step S220.

  In step S220, the CPU 401 shifts the stroke data of the correction area WE with a shift amount corresponding to the operation amount of the shift operation received in step S200 (the type of the operated direction key, the number of operations thereof, etc.). . The procedure of step S220 corresponds to the second shift processing procedure described in each claim.

  In step S230, the CPU 401 performs an erasing process for hiding the image based on the stroke data to be overcoated in the part whose position is superimposed by the stroke data of the correction area WE shifted in step S220. Do. In this modification, the procedures in steps S160 and S230 correspond to the first erasure processing procedure described in each claim. Thereafter, the process returns to step S180 and the same procedure is repeated.

  On the other hand, in step S210, if the operation accepted in step S200 is the confirmation operation, the processing shown in this flowchart is terminated.

  According to this modification, in conjunction with the automatic shift processing, the position of the stroke data in the correction area WE is shifted by the amount of shift desired by the operator by manual operation, so that the position of the stroke data to be reliably overcoated Can be superimposed.

(2) When Shift Processing is Performed Using a Preset Shift Amount In the above-described embodiment, a case has been described in which automatic shift processing is performed using a calculated shift amount, but the present invention is not limited to this. For example, as described above, the electronic correction tape 5 is often used with a large inclination with respect to the paper medium 70, and the inclination is often uniquely determined by the type of the electronic correction tape 5. That is, the amount of misalignment of the correction area WE is also uniquely determined depending on the type of the electronic correction tape 5. Therefore, in the present modification, a shift process is performed using a shift amount associated in advance with the writing instrument ID “ID2” associated with the electronic correction tape 5.

  Hereinafter, the control procedure executed by the CPU 401 of the operation terminal 4 based on the electronic writing process program in the present modification will be described with reference to FIG.

  12, steps S10 to S70, S160, and S180 are the same as those in FIG. 10 described above. When the CPU 401 determines the correction direction in step S70, the process proceeds to step S135.

  In step S135, the CPU 401 calculates the shift amount corresponding to the correction direction determined in step S70 previously associated with the writing tool ID “ID2” related to the stroke data of the correction area WE acquired in step S30. Obtained from the memory 404.

  In step S140 ′, the CPU 401 has moved away from the position of the stroke data in the correction area WE among the stroke data acquired in step S30 up to this point by the shift amount acquired in step S135. Stroke data such as a character at a position is determined as the stroke data to be overcoated. The procedure of step S140 ′ corresponds to the determination procedure described in each claim.

  Thereafter, in step S150 ′, the CPU 401 shifts the stroke data of the correction area WE acquired in step S30 with the shift amount acquired in step S135, and determines the position of the stroke data in the correction area WE. The position is superimposed on the position of the stroke data to be overcoated in step S140 ′. The procedure of step S150 ′ corresponds to the first shift processing procedure described in each claim. The subsequent step S160 is the same as in FIG.

  According to this modification, it is possible to surely correct the positional deviation of the correction area WE and superimpose the position of the stroke data in the correction area WE on the position of the stroke data to be overcoated.

(3) When erasing the unerased portion on the paper medium, that is, when the operator uses the electronic correction tape 5 to apply a character or the like to be corrected on the paper medium 70 as a white overcoat When there is a part that protrudes (so-called unerased part), the stroke data corresponding to the unerased part (or an image generated based on this) may be erased.

  Hereinafter, the control procedure executed by the CPU 401 of the operation terminal 4 based on the electronic writing process program in the present modification will be described with reference to FIG.

  In FIG. 13, steps S10 to S180 are the same as those in FIG. 10. In step S160, the CPU 401 performs the overcoating process of the portion where the position is superimposed by the stroke data of the correction area WE shifted in step S150. When the erasing process for hiding the image based on the stroke data is performed, the process proceeds to step S162.

  In step S162, the CPU 401 sets the top coat processing target based on the stroke data such as the character recognized in step S80, including the stroke data that is the top coat processing target whose position is superimposed by the stroke data of the correction area WE. Of the stroke data (stroke data of characters etc. to be corrected), the stroke data that is not superimposed on the position of the stroke data in the correction area WE and has not been erased in step S160 (the stroke of the unerased portion) Data) is determined. If there is unerased portion stroke data, the determination at step S162 is satisfied, and the routine goes to step S164. In this modification, the procedure of step S80 corresponds to a character recognition procedure.

  In step S164, the CPU 401 performs an erasing process for hiding the image based on the stroke data of the unerased portion. Note that the CPU 401 may perform the erasure process in which the stroke data of the unerased portion is deleted from the RAM 403 while being hidden. The procedure of step S164 corresponds to the second erasure processing procedure described in each claim. Thereafter, the process returns to step S30 and the same procedure is repeated.

  On the other hand, if there is no stroke data for the unerased portion in step S162, the determination in step S162 is not satisfied, and the same procedure is repeated by returning to step S30.

  According to this modification, even if there is a portion (an unerased portion) that protrudes from the white topcoat when the operator uses the electronic correction tape 5 to apply a character or the like to be corrected in white overcoat, the electronic data Above, it is possible not to delete or display an image generated based on the stroke data of the unerased portion. As a result, the operator's omission on the actual paper medium 70 can be automatically resolved on the electronic data, and the convenience can be further improved.

(4) When Using Other Correction Tools and Coloring Tools In the above-described embodiment and the like, the case where the electronic correction tape 5 that is a tape transfer type correction tool is used has been described. For example, a container-type correction tool or a pen-type correction tool (so-called correction pen) may be used. Also in this case, the same effect as the above-described embodiment can be obtained.

  Alternatively, in addition to or in place of the correction tool, a coloring tool (a so-called highlighter pen) that colors characters and images already described on the paper medium 70 and the periphery thereof with a transparent color may be used. When using a coloring tool, the operator places a transparent band-like colored region (for overcoating) on the portion on the paper medium 70 corresponding to the character to be colored among the characters already described on the paper medium 70. By writing (equivalent to the icon), characters or the like to be colored can be colored.

  The coloring tool is also often used with a large inclination with respect to the paper medium 70, like the correction tool such as the electronic correction tape 5 described above. For this reason, on the actual paper medium 70, the stroke data of the character or the like to be colored is displayed on the electronic data even though the overpainting is correctly performed by the coloring tool so as to overlap the character or the like to be colored. There is a possibility that the position of the stroke data of the overcoating portion by the coloring tool is shifted (not correctly superimposed) with respect to this position.

  Therefore, if the above-mentioned band-like colored area written in the paper medium 70 is detected by the coloring tool based on the stroke data stored in the RAM 403 as described above, the same method as in the above-described embodiment is performed. The positional deviation is eliminated, and the position of the stroke data of the band-shaped colored region and the position of the stroke data of the character or the like to be colored can be superimposed on the electronic data. As a result, correct electronic data reflecting the intention of transparent coloring by the operator can be performed, so that convenience can be improved.

(5) Others In the above description, when there are descriptions such as “vertical”, “parallel”, and “plane”, the descriptions are not strict. That is, the terms “vertical”, “parallel”, “plane”, etc., allow tolerances and errors in design and mean “substantially vertical”, “substantially parallel”, “substantially plane”, etc. It is.

  In addition, in the above description, when there are descriptions such as “same”, “equal”, “different”, etc., in terms of external dimensions and sizes, the descriptions are not strict. That is, the terms “same”, “equal”, “different”, etc. mean that “tolerance and error in design and manufacturing are allowed”, “substantially the same”, “substantially equal”, “substantially different”, etc. It is. However, if there is a description of a value that becomes a predetermined judgment criterion or a value that becomes a delimiter, such as a threshold value or a reference value, for example, “same”, “equal”, “different”, etc. It is different and has a strict meaning.

  The arrows shown in FIGS. 2 and 5 show an example of the signal flow, and do not limit the signal flow direction.

  Also, the flowcharts and routines shown in FIGS. 10 to 13 are not intended to limit the present invention to the procedures illustrated, but to add or delete procedures or change the order without departing from the spirit and technical idea of the invention. You may do.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
