Abstract

PURPOSE:To easily read a handwritten document including a graphic by judging image information written in a frame as characters and judging image information that crosses the frame as graphics. CONSTITUTION:When inputting characters, one character is written in an inner frame 17, and when inputting a graphic, the graphic is drawn unconscious of the inner frame 17. A reading section 8 reads the image information from a paper 7 and stores in an image storage section 13. A position detecting section 14 calculates positional information 18 from image information by a mark 9 and marks 91-94 and sends to a judging section 19. The judging section 19 judges image information 21 from the image storage section 13 from the positional information 18, and when the image information 21 is at the position of the inner frame 17, converts it to character code 24 by a converting section 20, and when the information crosses the middle frame 17 and extends to adjoining inner frame, stores the image data 21 as it is in a storage section 25.

Description

[Detailed Description of the Invention] [Summary] In reading and inputting characters and figures recorded on paper, paper on which a frame shape forming a square is printed is used, image information written within the frame is determined to be text, Person who determines that image information that exceeds the frame is a figure [Field of application for Graduation I-] The present invention relates to an improvement in an input method for reading and inputting characters and figures.

It is desired to simplify the method of reading and inputting paper on which a mixture of characters and figures are recorded.

[Conventional technology]

A conventional example will be explained using figures. FIG. 4 is a block diagram illustrating a conventional example.

Conventionally, a method using a tablet board 1 has been used to manually create characters and graphics. Tabshiso 1 ~ Board 1
A character area 2 and a graphic area 3 are provided. When inputting characters, by writing one character at a time in the tree notation 4 of the character area 2, the processing device 5 performs a discrimination process, and the characters are output to the output device (display device, printer, etc.) 6. . On the other hand, when inputting a figure, by drawing a desired figure in the figure area 3, the figure information I [3 is manually inputted.

As an input tool, you can use a stylus or a special pen, or you can write (or draw) characters or figures directly on the tablet board 1, or you can place a translucent paper on the top of the tablet board 1 and write it. Write letters and shapes from above
(or drawing) method etc. is adopted.

[Problem to be Solved by the Invention 1] As is clear from the above, the conventional method of manually inputting characters and figures has the problem of requiring a tablet board and special input tools.

[Means for solving problems]

In a system in which information recorded on paper 7 is read by a reading unit 8 and stored in a storage unit 25, an inner frame 17 forming a square 11 and marks 9 and 91 to 94 indicating the position of the inner frame 17 are printed. A paper 7, an image storage unit 13 that stores the input information 12 from the reading unit 8, and a position detection unit that outputs position information 1 [115] detected based on the image information of the four corner marks 91 to 94 in the input information 12. 14, and position information j indicating the position of the inner frame 17 based on the position information 15.
8, and determines whether the image data 21 specified by the position information 18 in the image storage unit 13 is located within the inner frame 17, and If the data exceeds the range of , send the image data 21 to section 10 25,
A determining unit 19 that starts the converting unit 20 when the data is within the inner frame 17; a converting unit 20 that compares the image data 21 and the character pattern 23 and outputs a character code 24 when they match; and the character pattern 23. and a character pattern section in which are stored.

[Effect]

The reading unit 8 reads the paper 7 and calculates 21 from the image information from the marks 9 and 91 to 94 in the inner frame 17.
If it is within the position, convert it to the character call l'24, or write the image information? When the image data 821 exceeds the inner frame 17 and extends to the adjacent inner frame 17, the image data 21 is stored in the storage unit 25 as is.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings. FIG. 2 is a block diagram for explaining one embodiment of the present invention, and FIG. 3 is a plan view of a sheet for explaining one embodiment of the present invention.

In the input method shown in FIG. 2, the paper 7 is written on the paper 7 in advance, and the paper 7 is inserted into the inner frame 17 forming the squares 11 as shown in FIG. 3 (al).
is, for example, blue (marks 91 to 94 are printed with diagonal lines on the right). Marks 91 to 94 are for detecting the position of the four corners of the paper 7, and mark 9 is for detecting the position of the inner frame 17. In addition, FIG. 3 (bl is a partially enlarged view of the sheet 7, and the boundary line 10i11 borders the inner frame Ii'iJ), and the space S indicates the interval between the marks 9.

When entering characters, write one character in each of the inner frames 17. When inputting a figure, the figure is drawn across each square of the inner frame 17. In other words, when inputting a figure, the figure is drawn without being aware of the inner frame 17.

The reading and inputting of characters and figures recorded on the paper 7 using the method described in L will be explained with reference to FIG.

■When the reading unit 8 reads the paper 7, the read input information (1゛ throat image information) 12 is stored in the image storage unit 1.
3. At this time, the image information of the mark fully stamped on the paper 7 is also read and stored at the same time, but since the inner frame 17 is blue, it is not read. Based on the mark image information corresponding to the mark 91 at the tenth left corner of the paper 7 shown in FIG.
Position information 15 corresponding to marks 91 to 94 is detected.

(2) The processing section 16 calculates the position information 18 of the inner frame 17 based on the position information 15, and sends this to the determination section 19. Note that the inner frame is a tree-shaped portion that forms the squares 11 as shown in FIG. 3 [b].

■The determination unit 19 accesses the image storage unit 13,
The address based on the given location information 18, that is, the address shown in FIG. 3 (
As shown in bl, the space between the inner frame 17 and the boundary line 10 is scanned in bit order to check the presence or absence of image information. Note that the boundary line 10 is calculated from the center position of the space S between the marks 9 shown in FIG. 3+11). When no image information is detected, the position information 18 is notified to the conversion unit 20.

(2) The conversion unit 20 takes out the image data 21 of the address based on the position information 18 from the image storage unit 13, compares it with the character pattern data 23 of the character pattern unit 22, and when they match, the corresponding character Output code 24. Note that characters that cannot be read as characters are output as image data 21 as is.

■Character code 24 L: I storage section (data storage) 2
It is stored in 5.

■If image information is found between the inner frame 17 and the boundary line 10 through the determination process in the above paragraph (■), the image data 21 at that address is stored in the storage unit 25 as is.
Transfer to.

Through the above processing, when the input information 12 on the paper 7 is read by the reading section 8, the information in the inner frame 17 is changed to the character code 2.
4, and the rest are ignored as graphic information and stored in the storage unit 25 as graphic image data 21.

〔Effect of the invention〕

The present invention facilitates the reading of handwritten documents including graphics,
Furthermore, since the read information is compressed, the capacity of the storage f# section can be reduced, and the transfer efficiency of the read information can be improved.
