FIELD OF THE INVENTION The present invention relates to a mark recognition device that recognizes mark data such as characters input from an image scanner or various communication terminals (such as a facsimile).

In recent years, mark recognition devices have been developed that use image scanners to read marks displayed so that they can be visually recognized, and recognize the reference pattern closest to the read mark pattern as the mark. If there is a reference pattern similar to a chapter pattern, a mark may be mistakenly recognized as that reference pattern, and there may also be marks that recognition algorithms cannot recognize. For this reason, there is a need for a mark recognition device that can improve the recognition rate by accurately picking up misrecognized marks and unrecognized marks such as "double" and correcting them to correct marks. Ru.

[Prior Art] FIG. 6 is a block diagram showing a general system used as a mark recognition device. In this FIG. 12 is a recognition processing unit that compares the mark pattern read by the image scanner 11 with a plurality of reference patterns and recognizes the reference pattern closest to the mark pattern as a mark; This is a display device having a display screen 1.3a that visually displays the mark recognized by the recognition processing section 12.

The display state of the display device j3 is controlled by a main controller 14 such as a personal computer. As shown, it is visually displayed on the display screen 13a of the display device ＠-3.

Furthermore, the main controller J4 has a function as candidate mark display means. This candidate mark display means is the display screen 1
3a When a mark that should be corrected among the marks displayed on 3a is identified by keyboard operation, mouse operation, etc., the identified mark is identified as a candidate mark to be corrected (i.e., a candidate mark for a misrecognized mark). ; mark patterns with similar feature amounts) are displayed on the display screen 13a.

With this configuration, the mark read by the image scanner 11 is processed by the recognition processing unit 12 for each mark, and the mark pattern is transferred to a plurality of references stored in a storage device (not shown) or the like. The pattern is compared and the reference pattern closest to the mark pattern is recognized as the mark. The recognition result is output to the main controller 14, and is visually displayed on the display screen 13a, as shown in FIG. In addition, in FIG. 7, four parts where "wa" was mistakenly recognized as "ne" are clarified and shown.

Since the recognition processing unit 12 itself cannot normally make a judgment to correct a misrecognized mark, the operator refers to the recognition result displayed on the display screen 1.3a and, if it is a text, corrects the misrecognized mark. With this in mind, we pick up misrecognized marks, unrecognized marks, etc., and decide which marks should be revised from a group of other marks with similar patterns.

In addition, when determining a revised mark, the operator uses the function of the candidate mark display means in the main controller 14 to
By specifying a misrecognized mark (for example, "Ne" in FIG. 7) with the cursor 13b, candidates for marks to be corrected (candidate marks) for that specific mark are displayed in the window 13c on the display screen 13a. can be displayed. Then, the operator can select a corrected mark from among these candidate marks, and can use the function of the candidate mark display means to assist in correcting a misrecognized mark or the like. For example, the seventh
In the case of "ne" in the figure, "ne", "wa", "tsu", "wa", etc. are displayed in the window 13c.

[Problems to be Solved by the Invention] However, in such conventional mark recognition devices, automatic search is not performed, and the operator refers to the recognition results displayed on the display screen 13a of the display device 13 character by character. Then, the operator determines whether the mark is misrecognized or unrecognizable while grasping the meaning of the text, etc., and then makes corrections.The efficiency of improving the recognition rate and shortening the correction time is left to the operator. There was a problem in that the burden on the operator was extremely heavy.

Furthermore, even if the function of the candidate mark display means is used, conventionally, the display position of the candidate mark window 13c on the display screen 13a is the position shown in FIG. 7, regardless of the position of the specified mark. Since the specific mark is fixed to the window 13c, the specific mark may become invisible due to the window 13c, and in such a case, operations such as left/right or up/down scrolling are time-consuming.

The present invention aims to solve the above-mentioned problems, and provides a mark recognition device that improves the recognition rate and shortens the time to correct incorrectly recognized marks while reducing the burden on the operator. The purpose is =7.

[Means to solve the problem] FIG. 1 is a block diagram of the principle of the present invention.

In this Figure 1, 1 is a mark reading means for reading a mark displayed so that it can be visually recognized, and 2 is a mark reading means for comparing the mark pattern read by this mark reading means 1 with a plurality of reference patterns. a mark recognition means that recognizes a reference pattern closest to the mark pattern as a mark;
3 is a display means for visually displaying the mark recognized by the mark recognition means 2; 4 is for controlling the display state in the display means 4; it has a candidate mark display means 5 and a same pattern display means 6; are doing.

When the candidate mark display means 5 specifies a mark to be modified among the marks displayed on the display means 3a, the candidate mark display means 5 causes the display means 3 to display candidates for marks to be modified for the identified mark. The present invention has a function of selecting an optimum position where a mark candidate does not compete with the display position of the specified mark and marks having the same pattern, and displaying the mark candidate at the optimum position.

Further, when the pattern display means 6 specifies a mark to be modified among the marks visually displayed by the display means 3, the pattern display means 6 distinguishes a mark having the same pattern as the specified mark from other marks. It is displayed on the display means 3 so that it can be displayed.

[Function] With the above-described configuration, in the mark recognition device of the present invention, the marks read by the mark reading means 1 are as follows for each mark:
The mark recognition means 2 compares the mark pattern with a plurality of reference patterns, and the reference pattern closest to the mark pattern is recognized as the mark. The recognition result is output to the main control section 4 and visually displayed on the display means 3.

When the operator specifies a mark to be modified among the marks visually displayed by the display means 3, the same pattern as the specified mark (hereinafter referred to as the specified mark) is displayed by the same pattern display means 6. The mark having the mark is displayed on the display means 3 so as to be distinguishable from other marks. Therefore, the operator can easily distinguish all the marks having the same pattern as the specific mark on the display means 3.

Further, when the operator specifies a mark to be corrected among the marks visually displayed on the display means 3, the candidate mark display means 5 displays candidates for marks to be corrected for the specific mark on the display means 3. It can be displayed in a window etc. At this time, the mark candidate is displayed at the optimum position by selecting the optimum position that does not conflict with the display position of the specific mark and marks having the same pattern by the function of the candidate mark display means 5. Therefore, the specific mark and marks with the same pattern will not be obscured by the display of the candidate mark.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings, but the hardware configuration of the mark recognition device of this example is exactly the same as the general system shown in FIG. 6.

In other words, an image scanner 11 (corresponding to the mark reading means 1 in FIG. 1) that reads marks such as characters and marks displayed so as to be visually recognizable, and a mark pattern read by the image scanner 11. A recognition processing unit 12 (corresponding to the mark recognition means 2 in FIG. A display device 13 (corresponding to the display means 3 in Figure 1) having a display screen 13a that visually displays the mark
and a main controller such as a personal computer (main controller 4 in FIG. 1) that controls the display state of the display device 13.
(equivalent to) 14 are provided.

The difference between the apparatus of this embodiment and the conventional apparatus is that the main controller 14 has the functions of the candidate mark display means 5 and the same pattern mark display means 6 shown in FIG. That's true.

In addition, in this embodiment, the pattern display means 11-6 operates according to the flow shown in FIG. Then, a mark having the same pattern as the specific mark is displayed on the display device 13 so that it can be distinguished from other marks. Here, the recognition result displayed on the display screen 13a actually contains codes such as characters and line breaks in a serial manner. Therefore, when a specific mark is specified with a cursor or the like, the pattern display means 6 recognizes the code of the specific mark as shown in FIG. Search for the same code in the file (Step A2), and display all the marks with the searched code (marks with the same pattern as the specific mark) differently from other marks (reverse display, shading, etc.). etc.) (step A3).

Further, in this embodiment, when the candidate mark display means 5 specifies a mark to be corrected among the marks displayed on the display device 13 using a cursor or the like, the candidate mark display means 5 displays the mark to be corrected for that specific mark. The function includes means for selecting an optimal position for a candidate and displaying the candidate at the optimal position.

Here, the candidate mark display means 5 uses the means explained in FIG. Select a position that does not conflict with the display position.

In the means (candidate mark display processing) shown in FIG. (including pattern marks) is calculated and determined (step B2). Then, based on the determined display position of the specific mark, a position where the display of the candidate mark does not conflict with the specific mark or a mark with the same pattern as this is determined as the optimal display position (step B3). Display candidate marks in a window (step B4)
).

Further, in the means shown in FIG. 4, the display screen 13a is set to 8 in advance.
Divide it into blocks and set simple display rules. For example, as shown in Fig. 4, if the specific mark is in block A, the candidate mark window 13c is displayed in the lower right block, and if it is in block B, the window 13c of the candidate mark is displayed in the upper right block.
The candidate mark is displayed in a window by setting a display rule such that if it is in block C, it is displayed in the upper left block if it is in block D.

With the above-mentioned configuration, in almost the same way as in the conventional case, marks such as characters and marks read by the image scanner 11 are first processed by the recognition processing unit 12 into a plurality of mark patterns for each mark. The reference pattern is compared with the reference pattern, and the reference pattern closest to the mark pattern is recognized as the mark. The recognition result is output to the main controller 14 and visually displayed on the display screen 13a of the display device 13 as shown in FIG. Here, Figure 5 shows a case where the same sentence as shown in Figure 7 is recognized and displayed, and in particular, four parts where "wa" was incorrectly recognized as "ne" are clarified and shown. .

In this embodiment, the operator selects the display screen 1.
Referring to the recognition result displayed on 3a, "wa" is changed to "ne".
If it is determined that it has been misrecognized as
By specifying any "ne" in the file a with a cursor or the like, the same pattern mark display means 6 of the main controller 14 will display the "ne" in the same file on the display screen 1.
3a, all of them are displayed in shading (see the shading display area 13d in FIG. 5). Therefore, the operator may
Screen 13 displays all marks with the same pattern.
At the same time, the function of the candidate mark display means 5 of the main controller 14 allows the user to easily distinguish the mark from other marks on The candidates are displayed on display screen 1 as shown in FIG.
3a, it is displayed in the window 13c at the optimal position that does not conflict with any "ne". In addition, in Figure 5,
Window 13c is shown in three places, but these three
All of the three windows 13c are at optimal positions, and in reality, the window 13c is displayed at one of these positions. Therefore, it is possible to reliably prevent the mark "NE" from disappearing due to window display. This eliminates the need to scroll up, down, left, and right on the screen.

In addition, in Figure 5, as candidate marks for the specific mark “ne”,
"Ne""Wa""T""Wa""b""I""
These are displayed in the window 13c, and the operator selects the candidate mark from among these candidate marks.
Select ``wa'' and correct the misrecognized ``ne''.

As described above, according to this embodiment, the same pattern mark display means 6 displays the specified mark and the mark with the same pattern so that they can be distinguished from other marks, so that the operator can The mark can be easily found on the display screen 13a, and there is no need to search for each mark that may have been misrecognized while understanding its meaning. Therefore, the burden on the operator is greatly reduced, and the recognition rate can be improved and the time required to correct erroneously recognized marks can be reduced.

Further, according to this embodiment, since the candidate mark display means 5 has a means for displaying the candidate mark at the optimum position, the window 13c for displaying the candidate mark can display the specific mark and marks having the same pattern. This eliminates the need for the operator to scroll up, down, left, and right as in the past, leading to a reduction in the time it takes to correct a misrecognized mark.

Although the above embodiment describes the case where the specific mark is "ne", the present invention is of course not limited to this.

In addition, in the above example, when the mark ``Ne'' is specified, all ``Ne'' marks are displayed so that they can be distinguished from other marks. It can also be displayed. In other words.

Now, if the correct word ``no'' in ``(noun) ten'' is misrecognized and becomes ``(noun) + O,'' if you specify ■noun) 10'', the type of (noun) will change. Regardless “(noun)
The rOJ portion of “+O” can also be displayed in a distinguishable manner.

Furthermore, in the quantity ratio embodiment, the case where the image scanner 11 is used as the mark reading means has been explained.
Various communication terminals such as a facsimile may also be used.

[Effect of the invention] As detailed above, the mark recognition device of the present invention (Claim 1
), the same pattern mark display means can display a specified mark and a mark with the same pattern so as to be distinguishable from other marks, so the operator can easily see the specified mark on the display means. It can be found among the displayed marks, greatly reducing the burden on the operator, improving the recognition rate, and shortening the time to correct incorrectly recognized marks.

Further, according to the mark recognition device (claim 2) of the present invention, the candidate mark display means displays the candidate mark at an optimal position (a position that does not conflict with the specific mark and marks with the same pattern). This feature prevents candidate marks from conflicting with specific marks and marks with the same pattern, eliminates the need for operators to scroll the screen, and reduces the time it takes to correct incorrectly recognized marks. This has the effect of further shortening the time.
