Therefore, it has been proposed to form a symbol representing each character forming a document on a sheet on which the document is recorded. That is, it has been proposed to create a document in which human-readable symbols such as letters and numbers, which are easily recognized by humans, and machine-friendly symbols that are easily recognized by machines are mixed.

The benefit of this proposal is that the machine symbols formed on the document are automatically recognized by the machine.
The point is that a document file that can be processed by a personal computer or a word processor can be obtained very easily without requiring key input work or the like. Therefore, the function of a recording medium such as a flexible disk can be added to the paper itself on which the document is recorded.

[0004]

However, the mechanical symbols recorded on the paper represent only the character codes that make up the document, and the arrangement of the text, the size of the font, and the size of the blank space are not shown. Such layout information is not included. Therefore, even if a document file can be obtained, reproduction of the original document in accordance with its layout requires further processing by a computer or a word processor, and reproduction of the original is not always easy.
Therefore, for example, when the original is written or the original becomes dirty due to dust or the like, it takes a considerable amount of labor and time to reproduce the original according to the layout.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described.
It will be described in detail with reference to the accompanying drawings. FIG. 1 is a conceptual diagram for explaining the concept of document reproduction according to an embodiment of the present invention. First, the structure of the original 1 to be reproduced will be described. The manuscript 1 has a first character area C1 formed on the upper stage,
It has a second character area C2 formed in the middle tier and a third character area C3 formed in the lower tier. In the middle, the second
A photo area P is formed alongside the character area C2.
Further, below the third character region C3, there is a first code region MC1 corresponding to the first character region C1, a second code region MC2 corresponding to the second character region C2, and a third character region C3. The third code area MC3 is formed in order from left to right. There is no code area corresponding to the photo area P. Reference numeral 80 denotes writing or stains, which did not initially exist on the surface of the original 1.

First, second and third code areas MC1,
In MC2 and MC3, the character codes of the characters included in the first, second and third character areas C1, C2 and C3 are represented by machine symbols. A two-dimensional code can be given as an example of the mechanical symbol. One example of a two-dimensional code is a multi-stage barcode consisting of barcodes stacked in multiple stages. As a specific example of the multi-stage barcode, a PDF417 code can be cited. The PDF417 code is described in detail in Japanese Patent Laid-Open No. 5-290204, for example.

Code areas MC1, MC2 and MC3
Are arranged according to certain rules. That is, the code area corresponding to the leftmost character area on the uppermost stage of the original 1 is formed on the leftmost side of the lower end of the original 1. The code area corresponding to the upper part of the document 1 is formed on the left side. For character areas having the same starting point (upper left corner) height, the code areas corresponding to the character areas located on the left side are arranged on the left side.

In this embodiment, the original 1 is read by the digital copying machine 10 and code areas MC1 and MC2 are read.
Based on the two-dimensional code formed on MC3 and MC3, reproduced image 1A free from dirt 80 is created. The digital copying machine 10 is provided with a document table 11 made of transparent glass on the upper surface. The document 1 is placed on the document table 11 face down and is read while being held down by the document holder 12. A start key 13 for starting document reading and an input key group 14 including a plurality of keys for making various settings are provided on the upper surface of the digital copying machine 10 in front of the document table 11. There is.

FIG. 2 is a sectional view showing the internal structure of the digital copying machine 10. Below the document table 11, a scanner unit 15 as a reading unit for reading a document image is provided. An image forming unit 30 for forming a reproduced image of a document on a sheet supplied from a sheet supply unit (not shown) is provided below the scanner unit 15. Scanner unit 1
Reference numeral 5 includes a light source 16 such as a halogen lamp for scanning the original while illuminating it. The light generated from the light source 16 is reflected in the horizontal direction by the first reflecting mirror 21 that is transported together with the light source 16. The light from the first reflecting mirror 21 has its optical path folded back by the second reflecting mirror 22 and the third reflecting mirror 23, passes through the lens 17 and the moire filter 18, and enters the one-dimensional CCD sensor 20. The light source 16 and the first reflecting mirror 21 are conveyed along the document table 11. Further, the second and third reflecting mirrors 22 and 23 are transported along the document table 11 at a speed half the transport speed of the light source 16 and the like. The light source 16 and the first to third reflecting mirrors 21, 2
2 and 23 have an optical motor 25 as a drive source.

The one-dimensional CCD sensor 20 outputs an image signal representing the optical image of the original image formed on its light receiving surface. This image signal is input to the reading control board 26. The reading control board 26 is an image processing circuit for processing an image signal,
And a read control circuit for controlling the optical motor 25 and the light source 16. The original is read by the one-dimensional CCD sensor 2
0 for electrical main scanning and the sub-scanning direction Y of the light source 16, etc.
This is achieved by the combination with the sub-scanning of the document by the conveyance to the document. The CCD sensor 20 includes a plurality of detection elements arranged in a line along the main scanning direction X (direction perpendicular to the paper surface of FIG. 2). The image of the document on the document table 11 is read for each minute pixel corresponding to each detection element. CCD
The sensor 20 outputs an image signal representing the density of each pixel.

The image forming section 30 forms an image on a recording sheet according to an electrophotographic process. Specifically, the image forming unit 30 includes a drum-shaped photoconductor 31 and a laser exposure device 32 for selectively exposing the photoconductor 31. The laser exposure device 32 generates a laser beam that is modulated according to the image to be recorded. Laser exposure device 3
The surface of the photoconductor 31 before being exposed by 2 is uniformly charged by the main charger 33. Therefore, the photoconductor 1 is selectively exposed by laser light.
An electrostatic latent image corresponding to the image to be recorded is formed on the surface of the. This electrostatic latent image is developed into a toner image by the developing device 34. This toner image is transferred to the transfer charger 3
By the function of 5, the image is transferred onto the sheet conveyed to the transfer area 36. The sheet on which the toner image is transferred is guided to the fixing device 38 by the conveyor belt 37. The fixing device heats and pressurizes the paper between the pair of rollers 38a and 38b to fix the toner particles to the paper. On the other hand, the surface of the photoconductor 31 after the toner image is transferred is cleaned by the cleaning device 39 to remove the residual toner.

FIG. 3 is a block diagram showing the electrical construction of the essential parts of the digital copying machine 10. The image signal output by the CCD sensor 20 is converted into digital image data and temporarily stored in the image memory 41. The image data stored in the image memory 41 is further subjected to image processing such as area discrimination processing and layout detection processing in an image processing unit 42 having a function as a layout detection unit. Of the image data after the image processing, the data of the portion corresponding to the two-dimensional code is input to the decoder 43. The decoder 43 refers to the table 44 and decodes the read symbol. The table 44 stores, for example, a two-dimensional code pattern and a character code in association with each other. In this case, the decoder 43 acquires the character code corresponding to the read symbol from the table 44 and outputs it. The output of the decoder 43 is input to a print data creation unit 60 which is an image creation unit for creating image data representing a reproduced image of a document. Also, the decoder 43
Can be input to a document processing device such as a personal computer or a word processor via an external interface (I / F) 45.

The decoder 43 inputs a signal indicating whether the decoding of the two-dimensional code has succeeded to the CPU 50 via the line 53. In addition to the CPU 50,
From the operation unit 55, an operation signal of the input key group 14, a start key 13 and is input, The display unit 61 for displaying the main Tsu message or the like is connected. CPU50
Controls input / output of image data to / from the image memory 41. The CPU 50 also controls the image processing unit 42 and the reading control circuit 51. Read control circuit 5
1 controls the operation of the optical motor 25 via an interface (I / F) 52 based on a command from the CPU 50, controls the amount of light generated by the light source 16 via an interface (I / F) 56, and The detection operation by the CCD sensor 20 is controlled.

The print data creating section 60 uses the line 63.
The image data stored in the image memory 41 can be acquired via the. Further, the print data creation unit 60 acquires information regarding the layout of the document from the image processing unit 42 via the line 62. The print data creation unit 60 acquires from the font memory 65 a font image corresponding to the character code given from the decoder 43. Then, based on the layout information provided from the image processing unit 42, the image data from the image memory 41 and the font image are combined to create image data representing a reproduced image of the document. This image data is printed by the print function unit 6 including the image forming unit 30 and the like.
6, the reproduced image of the original is formed.

The layout information generated by the image processing unit 42 includes the coordinates of the start and end points of the character areas C1, C2 and C3, the photograph area P, and the code areas MC1, MC2 and MC3. The starting point is the upper left corner of the area,
The end point is the lower right corner of the area. For example, character area C
The start point of 1 is the position indicated by reference numeral 91, and the end point is the position indicated by reference numeral 92. The starting point of a region gives the position of the region. Also. The shape and size of the region can be known based on the starting point and the ending point of the region.

The image processing unit 42 prints the coordinates of the end point and the start point of each area and area identification information indicating whether the area is a character area, a two-dimensional code area, or another area such as a photograph or an illustration. Input to the data creation unit 60. A known technique can be applied to the area separation processing for detecting each area and determining the type of each area. For example, regarding the separation of halftone image areas such as photographs and character areas, the 17th volume of the Institute of Electronics, No. 5 (1988) No.
Pages 258-266, Journal of the Institute of Image Electronics Engineers of Japan, Volume 13, No. 1 (198
4) Described on pages 29 to 37. The same technique can be applied to the determination of the two-dimensional code area. For example, since the two-dimensional code area is formed by repeating a pattern of a certain characteristic, the standard characteristic amount is previously stored in a memory (not shown), and the standard characteristic amount and the image memory 4 are stored.
The area determination can be performed based on the degree of difference or the degree of similarity with the feature amount extracted from the image data stored in 1.

FIGS. 4, 5 and 6 are flow charts for explaining the processing for creating a reproduced image of the original 1. Place the original 1 on the original table 11 (step S
1) Close the document holder 12, and then press the start key 13
When is pressed, the light source 16 and the like are conveyed in the sub-scanning direction Y, and the surface of the document 1 is scanned (step S2). The image signal output from the CCD sensor 20 during the scanning process is converted into digital image data and stored in the image memory 41. The image processing unit 42 uses the image memory 41.
The above-described area separation processing is performed based on the image data inside (step S3). Specifically, each part of the document is classified into one of a two-dimensional code area, a character area, and another area. Then, each area is detected as a rectangular area, and the coordinates of the upper left corner and the lower right corner of this rectangular area are obtained and stored in a memory (not shown).

Next, it is judged whether the separation of the two-dimensional code area has succeeded (step S4). When the separation of the two-dimensional code area fails, a signal indicating this is sent from the image processing unit 42 via the line 54 to the CPU 50.
Given to. As a result, normal copy processing is performed without using the reading result of the two-dimensional code (step S).
5). Details of the normal copy processing will be described later.

When the separation of the two-dimensional code area is successful, the image data of the separated area is input to the decoder 43. The decoder 43 refers to the table 44 based on the symbol image represented by the image data and
The dimension code is decoded to generate a character code string (step S6). In the next step S7, it is determined whether the decoding process has been successfully completed. The signal indicating the success or failure of the decoding process is sent from the line 53 to the CPU 5
Input to 0. When the decoding process is unsuccessful, the normal copy process is performed (step S5).

When the decoding of the two-dimensional code is successful, the coordinates of the upper left corner and the lower right corner of each character area, which are obtained by the image processing unit 42 and are stored in the memory, become
It is given from the line 62 to the print data creation unit 60 (step S8 in FIG. 5). Print data creation unit 60
If there is an area other than the character area (step S
9) and the coordinates of those areas (the coordinates of the upper left corner and the upper right corner of the rectangular area) are acquired from the image processing unit 42 (step S
10) The images in these areas are cut out from the stored image in the image memory 41 (step S11). If the original includes only the character area, steps S10 and S1
The processing of 1 is omitted.

In step S12, the font stored in the font memory 65 is used to create a reproduced image corresponding to each character area based on the text data (character code) represented by the two-dimensional code. Print data is created. Specifically, the size of the font is selected based on the size of the character area and the number of characters included in the character area so that all the characters fit in the character area. Then, the font of the selected size is read from the photo memory 65, and the print data corresponding to the reproduced image of the character area is created by the read font.

The print data for the character area is obtained in step S.
8 and the layout information acquired in S10,
It is combined with the image data of the other area cut out from the stored image of the image memory 41. As a result, print data corresponding to the entire reproduced image is created (step S1).
3). The print data corresponding to the entire reproduced image is input to the printing unit 66. As a result, the image forming unit 3
The reproduced image of the original is reproduced on the sheet by the action of 0 (step S14). As shown in Figure 1,
Although dirt 80 is present in the area extending over the character areas C1 and C2 of the manuscript 1, the character areas C1 and C2 are
Since it is reproduced based on the two-dimensional code, the reproduced image 1
In A, there is no image corresponding to the stain 80.

The reproduction of the code areas MC1, MC2 and MC3 may be performed based on the image data stored in the image memory 41, but the image representing the two-dimensional code is obtained based on the decoding result of the two-dimensional code. It is preferable that the data is newly generated. In this case, the two-dimensional code is recorded at the position corresponding to the position coordinates of the code areas MC1, MC2 and MC3.

The reproduced image does not necessarily have to be reproduced on the sheet, and print data corresponding to the reproduced image
It may be transferred to an external device such as a personal computer or a word processor. Next, the normal copy process (step S5 in FIG. 4) will be described with reference to FIG. This process is performed when the separation of the two-dimensional code area fails or the decoding of the two-dimensional code is defective. First, the CPU 50 causes the display unit 61 to display
A message indicating that the reading of the two-dimensional code has failed and a message for inquiring whether or not to perform a normal copy using the image data in the image memory 41 as they are are displayed (step S51). When a normal copy is desired, the operator presses the start key 13 within a fixed time (for example, within 10 seconds) (step S52). As a result, the CPU 50 gives an instruction via the line 64 to the print data creation unit 60 to create print data for image reproduction based on only the image data in the image memory 41. As a result, the reproduced image of the document is formed by the function of the printing unit 66 (step S53). If the original 1 has stains 80, the reproduced image also includes an image corresponding to such stains.

If the start key 13 is not pressed within a fixed time after the message is displayed, the process is terminated without performing the document reproducing operation. As described above, according to the present embodiment, the character area, the two-dimensional code area, and the other area are separated, and the information regarding the layout of each area (the coordinates of the upper right corner and the lower left corner of the rectangular area) is detected. Then, for the character area, print data representing a reproduced image is created based on the two-dimensional code. That is, a font having an appropriate size is selected based on the layout information, and the character area is reproduced at the same position as the original. This character area contains a character string obtained by decoding the two-dimensional code. Further, for the area other than the character area, the original image is reproduced using the image data acquired by the scanner unit 15 as it is.

In this way, it is possible to obtain a reproduced image of the original in which the character area and the photograph area are mixed while using the two-dimensional code. Therefore, it is possible to obtain a reproduced image without stains 80 in the character area, and moreover, it is possible to obtain a reproduced image whose layout is almost the same as that of the original. In addition, for example, when characters for explaining a photograph are recorded near the photograph region P, it is possible that two-dimensional codes corresponding to those characters are not recorded. In this case, there is a possibility that the character area and the code area may not be appropriately associated with each other, and the layout according to the original may not be reproduced. In order to prevent such a problem, for example, with respect to the photograph area, an area slightly larger than the actual area may be cut out. As a result, the character string for the description of the photo will be included in the photo area,
It is possible to prevent these character strings from being associated with the code area.

Although the present embodiment has been described above, the present invention is not limited to the above embodiment. For example, in the above embodiment, the two-dimensional coded information is only the character code, but the position information of each character area may be coded together.
For example, the coordinate position of the upper left corner of each character area in the original may be two-dimensionally coded and recorded in the original. To convert the coordinates of each character area into a two-dimensional code, for example, a document before forming the two-dimensional code is read by a scanner to create a bit image. A region separation process is performed on this bit image to extract a character region, and the coordinates of the upper left corner are acquired. The acquired coordinates may be two-dimensionally coded together with the character codes of the characters forming each character area and recorded on the document. The acquisition of the coordinates of the character area at the time of creating the document can also be performed by a manual operation. Specifically, the bit image of the original image is displayed on a display device such as a CRT, and the upper left corner of the character area is pointed by a pointing device such as a mouse. The coordinates of the pointed position may be acquired as the coordinates of the character area.

It is also conceivable that the information of the document created by the word processor is two-dimensionally coded including the control information regarding the layout.
In this case, all layout information such as line spacing, character spacing and fonts is obtained by decoding the 2D code. In this case, if the two-dimensional code can be decoded, the original can be reproduced extremely faithfully.

In the above embodiment, the reproduced image 1A also includes the image of the two-dimensional code, but the reproduction of the two-dimensional code may be omitted if necessary. Further, in the above-described embodiment, the character area and the area other than the character area are all reproduced, but for example, only the character area may be reproduced according to the layout of the document. Further, in the above embodiment, the two-dimensional code is taken as an example of the mechanical symbol, but a barcode recognized as a one-dimensional code may be used as a mechanical symbol for recording characters and the like.

Further, although the above embodiment has been described by taking a digital copying machine as an example, the present invention can be widely applied to an apparatus having an image reading unit such as a facsimile machine or an image scanner. In addition, various design changes can be made within the scope of technical matters described in the claims.

[0039]

As described above, according to the present invention, information regarding the layout of a document is acquired based on the image signal. Then, the information obtained by decoding the mechanical symbols is processed based on the layout information, whereby data representing the reproduced image of the original is created. As a result, while using the information represented by the machinery symbols, can you to create data representing substantially reproduced image of the document as per layout.

Further, the image signal representing the undecoded information is extracted from the image signals output by the reading means, and the information corresponding to this image signal and the decoded information are combined . Information other than the information recorded by the mechanical symbols can be reproduced. As a result, the information recorded by the machine symbol can be reproduced accurately, and other information in the document can be reproduced without omission.
