DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prints an optically readable encoded image obtained by encoding audio and image data and various other data that can be handled by a computer. The present invention relates to a method for manufacturing a printed matter.

[0002]

2. Description of the Related Art Conventionally, optical reading such as one-dimensional or two-dimensional barcodes obtained by encoding data such as voice and image data and other various data that can be handled by a computer is known. It is already known to print possible coded images on various prints, such as books, magazines or newspapers.

A specific example thereof is disclosed in Japanese Patent Application Laid-Open No. 6-231466 by the present applicant.

According to the disclosure in the above publication,
A large amount of data such as voice can be printed directly on paper in the form of a dot code as an encoded image.Therefore, in printed matter such as books, magazines, or newspapers, in addition to characters, pictures, photographs, and even voice, By printing and manually reading the dot code with a dedicated reading device, a new value is provided that allows the user to easily listen to the sound while watching the character, picture, or photograph.

The physical format of the dot code is as shown in FIG.

That is, the dot code 1 is composed of a plurality of blocks 2 arranged two-dimensionally adjacently.

Each block 2 is composed of a black dot or a white dot (FIG. 5) in which data divided for each block of data such as audio to be recorded corresponds to its value "1" or "0". In (A), white, which is the color of paper as a print medium, is read instead of the white dots.) The data dot pattern portion 3 that exists as a dot image according to a predetermined two-dimensional array, and the data dot pattern A marker 5 having a fixed number of continuous blacks arranged at the four corners of each block 2 used to find a reference point for reading each dot (data dot 4) in the section 3
And a block address pattern 6 including an error detection or error correction code disposed between the markers 5 so that each of the blocks 2 can be identified at the time of reading.

In FIG. 5A, straight lines drawn in the vertical and horizontal directions in the block 2 are imaginary lines for indicating the coordinate position of each data dot 4 for convenience.

FIG. 5B is a diagram showing an electrical functional block configuration of a reading device 7 for manually scanning the dot code 1 and optically reading the dot code 1.

That is, L for illuminating the dot code 1
A reading unit 8 including an illumination unit composed of an ED or the like, an optical system that forms an image of reflected light from the dot code 1, and an area sensor such as a CCD that captures light formed by the optical system; A binarization processing unit 9 for binarizing the output image signal with a predetermined binarization threshold; and a binarization processing unit 9
A binarized image memory 10 for storing binarized image data binarized by the above, and reading out the binarized image data stored in the binarized image memory 10 to detect each data dot 4, and A restoration unit 11 that assigns a value of “1” or “0” to each detected data dot 4 and outputs the data, a demodulation unit 12 that demodulates the data output by the restoration unit 11, A reproducing unit 1 that reproduces and outputs data such as original sound by performing an error correction process using a Solomon code or the like and a decompression process of the data subjected to the error correction process.
3 and an output unit 14 configured by a speaker, a CRT screen, or the like, which outputs data such as the original sound reproduced by the reproduction unit 13 in such a manner that the reader can recognize it.

Here, when the restoring unit 11 reads out the binarized image data stored in the binarized image memory 10 and detects each of the data dots 4, the restoring unit 11 first reads out the binarized image data from the binarized image data. A marker 5 is found, and a reading reference position of the data dot 4 is obtained based on the barycentric position of the found marker 5, and the data dot pattern portion is obtained from the obtained reading reference position of the data dot 4. A dot reading point for reading each data dot 4 in 3 is detected, it is determined whether the detected dot reading point is white or black, and a value of “1” or “0” is assigned to output data. It is configured to be.

The demodulation section 12 is a section for performing a process for returning the data such as audio input as a recording target to the original data before modulation since the data has been subjected to a modulation process in advance.

That is, this modulation process is a process which has been previously performed in the restoration section 11 to make it easier to find the marker 5 first. The data dots 4 in the data dot pattern section 3 and the marker 5 is applied to the input data such as voice so that the number of continuous black dots in the data dot pattern portion 3 is smaller than the number of continuous black dots forming the marker 5. Processing.

According to the above-described dot code 1 and the reading device 7, even if the entire size of the dot code 1 is larger than the imaging field of view of the reading device 7, in other words, the dot code 1 is read. Even if it is not possible to capture an image in one shot by the device 7, each address given to each block 2 is stored in the data dot 4
In addition, if the data can be detected in block units, the data contained in each block can be collected and the entire original data can be reconstructed.

Accordingly, it is possible to print a large amount of data such as voice on a paper surface, and the original data can be easily read using a reading method called manual scanning.

[0016]

By the way, there is still a problem to be solved in the following points with respect to a method of manufacturing a printed matter such as a book, a magazine, or a newspaper on which an encoded image such as a dot code is printed. It has been found.

That is, in manufacturing a printed material on which this type of coded image is printed, whether data such as voice can be reproduced and output as expected by a reader from the coded image actually printed on the paper surface of the printed material. It was necessary to ensure that such confirmation had been made, and a new situation had to be sought to determine how to perform the work for that confirmation.

Specifically, for example, when data actually printed as an encoded image is audio, the audio is actually reproduced and output, and the quality of the sound at that time is directly checked by ear. If the data printed as the encoded image is text data representing characters, the characters can be output and displayed on a screen or the like to visually confirm the correctness. is there.

The present invention has been made in view of the above circumstances, and an encoded image equivalent to an encoded image actually printed on the paper surface of a printed matter is printed in advance by a printer, and the equivalent encoded image is printed. It is an object of the present invention to provide a method of manufacturing a printed material that enables a predetermined confirmation of data such as sound included in an encoded image actually printed on the printed paper by using the same.

[0020]

In order to achieve the above-mentioned object, a method for producing a printed material according to the present invention is directed to a method for printing an optically readable encoded image obtained by encoding data such as voice. In the method for manufacturing a printed material to be performed, a first step of performing the encoding process on the data such as the audio to generate the encoded image, and a method of determining the encoded image generated in the first step by a predetermined process A second step of printing by a printer optically readable on a print medium of
A third step of performing a predetermined check on the data such as the sound included in the encoded image printed in the second step, and the first step according to a result of the check in the third step. A fourth step of optically readable printing the encoded image generated in the above on a predetermined print medium,
It is characterized by including.

That is, according to the method of manufacturing a printed matter, an encoded image equivalent to the encoded image actually printed on the paper surface of the printed matter is printed in advance by a printer. By using, predetermined confirmation can be performed on data such as sound included in the encoded image actually printed on the paper surface of the printed matter.

[0022]

Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment] FIG. 2 shows a case where audio data is converted into image data of a dot code 1 consisting of a set of two-dimensional dots, and a printed matter in which this image data (dot code) is printed is created. An authoring encoding system as shown in FIG. At the center of the authoring encoding system is a computer as an information processing device.
This is explained using a system that uses.

That is, a keyboard 101 and a mouse 102, which is a pointing device, for the operator to perform input and control instructions are connected to the PC body 100. Also, P
A display device 103 such as a CRT or a liquid crystal is connected for checking the processing result by the C body 100. And
A DAT (digital audio tape) player 104, an MO (magneto-optical disk) drive device 105, and the like are connected for inputting audio data. Further, a speaker 106 is also connected for confirmation of reproduction of audio data. Then, a printer 107 for encoding the audio data and for printing out the encoded image data thus created is connected. With such an authoring encoding system, encoded image data can be created from audio data.

By the way, the encoded image data which can be created by the authoring encoding system, it is difficult to use an extremely fine dot as a constituent unit due to problems of printing resolution and reading resolution of a reading device (scanner). difficult. Therefore, it is necessary to use a dot having a certain size as a constituent unit. The audio data has a considerably large data amount depending on the sampling frequency, bit rate, and time. Therefore, when audio data is converted into dot code image data, it is necessary to perform a considerably large compression process in order to reduce the size of the dot code including audio data of a certain length. . In addition, if the compression rate is to be increased as the compression processing in this case, the compression rate is limited in the reversible compression processing. Therefore, if the compression processing by the irreversible compression is performed, the compression rate can be increased. In this case, since the audio data is lossy compression, the audio data obtained by expanding and restoring the compressed audio data does not return to the same as the original audio data before the complete compression. Therefore, there may be a case where the sound quality deteriorates in the sense of hearing. Therefore, in the operation procedure for creating a dot code for printing from audio data, a confirmation operation for checking sound quality is very important.

The problem of sound quality is also greatly affected by the characteristics of the audio circuit of the device that performs reproduction, and the characteristics of output devices such as speakers and earphones. It is necessary to actually print the converted audio data, read it with a reading device (scanner) used in the actual use scene, play it back using an audio circuit, speakers, earphones, etc. actually used for playback and listen to it There is.

If there is a problem with the sound quality after the trial listening, the parameter (compression ratio, etc.) for performing compression in dot coding is changed, the audio data is processed, or the audio data is recorded again. After that, it is necessary to repeat the process of dot-coding, image-forming, printing, reading and reproducing using a reading device used in an actual use scene, and listening again.

In general, when a printed matter is created, paper information such as characters, pictures, and photographs is processed in a DTP (desktop publishing) environment, proofreading is performed, and the paper layout and color condition of the proofed printed matter are processed. Generally, a method is adopted in which a confirmer confirms the above and makes corrections as necessary, and then shifts to a printing process for mass production. The printing of the proof print may be performed using the same printing machine as the printing for mass production, or may be performed using a dedicated printer.

When the sound quality check of the dot-coded audio data is also performed by the proof printing, the proof printing by the printing machine is suitable for producing a large amount of the same data due to the printing characteristics. However, it is anticipated that a problem may occur in the sound quality in advance, such as printing a small amount of data for the sound quality check as described above, and a plurality of checks may be performed. It is often not economically feasible to print a small amount of data. Also,
Even if there is no problem economically, if you print and listen to the sound quality check and find that there is a problem with the sound quality,
In some cases, it may be necessary to re-record the audio data. However, in consideration of the time required for printing, it takes a very long time to lay out the data, print it out, listen to it, and re-record it.

When sound quality is checked by proof printing by a dedicated printer, the printing resolution of the printing press and the printing resolution of the proof printing printer are often different from each other. If the output dot code is directly output to a proof printer, the size of the imaged dot code will be different. One of the important purposes of proof printing is to check the layout of the paper, and if the sizes are different, the purpose of checking the layout cannot be fulfilled. It is also possible to give priority to dot code size information, convert the resolution, and output it to a proof printer.
In this case, the constituent dots of the dot code cannot be accurately reproduced, and the dot code cannot be read by the reading device. Therefore, the original purpose of reading the dot code by the reading device and checking the sound quality cannot be achieved.

Therefore, the printing of the dot code for checking the sound quality is not performed by proof printing, but by an authoring encoding system that encodes a separate dot code at the stage where the dot code which is the preceding stage is encoded and created. It is convenient to perform output (printing) by a device that can immediately output on the spot by the printer 107 connected to a certain PC or the like. That is, in the present embodiment, in the authoring encoding system that creates print data that is image data for printing dot-coded audio data on a publication or the like, the resolution of the printing machine for printing on the printing machine is The image data that has undergone the combined two-dimensional imaging and the image data that has been subjected to the two-dimensional imaging according to the resolution of each device of the printer 107 that outputs the image data for output by the printer 107 for sound quality checking ( This is hereinafter referred to as a confirmation code.) It is characterized in that a dot code as two image data is created for one original audio data.

Hereinafter, the flow of the encoding operation according to the present embodiment will be described with reference to a code printed matter production operation flowchart shown in FIG.

A, B, and C, which are separated by long vertical dotted lines in FIG. Here, A is an operation performed by a printing company, B is an operation performed by a publisher, and C is an operation performed by an encoding service provider that performs an encoding operation. However, in the work of actually creating a publication, the encoding service is not used, and the publisher performs the encoding work (B and C together) or the printing company performs the encoding work (A
And C together) are also possible. In the case where the publisher itself also serves as the encoding service provider, the following two sound quality checking steps (steps S405 and S406) can be combined into one sound quality checking step. Also, in the figure, the code layout work is described as the work sharing performed by the printing company A, but the code layout work is described as B
It is also commonly done by publishers.

First, the publisher B collects (creates, etc.) sound materials that the user wants to put on the printed matter (step S401). The collected or created audio data is provided by the encoding service provider C
Passed to.

The encoding service provider C encodes the received audio data according to the instruction from the publisher B (step S402).

In this encoding process, first, DAT
The audio data is fetched using the player 104, the MO drive device 105, or the like. It should be noted that the audio data passed from the publisher to the encoding service provider may be DAT, CD, MD, compact cassette, or stored in the MO in the form of digital audio data already loaded on a PC. Therefore, first, as shown in FIG. 2B, it is determined whether the audio data, which is the input data to be processed on the PC, is analog data or digital data (step S50).
1). Then, in the case of analog data, since it is necessary to digitize (binarize) first, digitization is performed at a sampling rate and the number of quantization bits suitable for use in a dot code (step S502). On the other hand, if the data is digital data, it is not necessary to perform the digitization process, but since the sampling rate and the number of quantization bits may be different from the sampling rate and the number of quantization bits used in the dot code, the dot code may not be used. The conversion and adjustment of the sampling rate, the number of quantization bits, stereo / monaural, etc. are performed (step S503). Various parameters are set for the data digitized in this way to perform the next stage of encoding (step S5).
04). Then, according to a parameter setting instruction such as designation of a compression ratio or designation of an error correction strength, encoding processing for compression or error correction is performed (step S505). Thus, the encoding process is completed.

[0037] In the encoding service provider C,
From the data encoded in step S402, an encoded image for confirmation to be output by the printer is generated (step S403). Then, the check code, which is the generated check encoded image, is output by the printer 107 (step S404). After that, the confirmation code output by the printer 107 is read by the reading device, and the reading device decodes and reproduces and outputs the voice. First, the encoding service provider C listens to check the sound quality (step S405).

As a result of the sound quality check, if it is determined to be NG, it is determined whether or not it is necessary for the person in charge of the encoding service provider C to improve the sound quality by editing the audio data, and to improve the sound quality by the editing processing. It is determined whether or not is possible (step S408). The editing processing here includes operations such as adjustment of the sound length by inserting or deleting a silent portion, changes in frequency characteristics by an equalizer, noise removal, and processing of audio data by various filters. The sound quality can be improved by the editing process,
If it is determined that it is necessary, the audio data is edited (step S409). Then, the audio data on which the editing processing has been performed is again performed in step S4.
02 is started again. If it is determined in step S408 that it is not necessary to perform the editing process, sound quality improvement is attempted by adjusting the settings of various encoding parameters, such as changing the compression ratio during the encoding process. Is performed.

Further, if the sound quality is OK as a result of the sound quality check in step S405, the confirmation code printed out by the printer 107 is encoded in order to have the publisher B confirm the sound quality as a final confirmation. It is passed from the service provider C to the publisher B.

At the publisher B receiving the confirmation code, the person in charge reads the confirmation code with a reader,
The sound is reproduced and output, and the sound quality is checked (step S4).
06). If the result of the sound quality check is NG, it is determined whether it is necessary to improve the sound quality by redoing the collection and creation of the sound material, that is, by replacing the sound material (step S407). If it is determined that the sound material needs to be collected and created again, the collection and creation of the above-described step S401 is performed again, and the collected and created sound material is returned to the encoding service provider C. If it is not necessary or impossible to redo the collection and creation of the sound material, the encoding service provider C is requested to improve the sound quality by editing the audio data and changing the parameter settings at the time of encoding. Upon request, the encoding service provider C will redo the encoding in step S402 in accordance with the instruction from the publisher B. On the other hand, if the sound quality is checked as a result of the sound quality check in step S406, the encoding service provider C is instructed to create a print code.

The encoding service provider C instructed by the publishing company B to create a printing code performs encoding again to create an encoded image for printing for printing by a printing machine (step S410). An encoded image for printing is generated from the encoded data (step S411). Then, the created encoded image for printing is passed to the printing company A.

In the printing company A, the coded image for printing is laid out on a printed material by DTP (step S412), and proof printing is performed (step S413). And the proof-printed paper is
Handed over to publisher B.

The publisher B checks the layout received from the printing company A (step S414). Here, if the layout check result is NG, the printing company A is instructed to redo the code layout, and the printing company A instructs the DTP of the above-described step S412.
Layout will be redone. On the other hand, if the layout check result is OK, the publisher B issues a printing start Go instruction to the printing company A.

In response to this Go instruction, printing company A:
Mass printing by the printing machine is started (step S41).
5).

As described above, according to the present embodiment,
The encoding authoring system creates a confirmation code that can be immediately printed out to the printer 107 for sound quality confirmation, and by checking the sound quality, the printing process by the printing machine can be reduced. It is possible to reduce the time and cost of creation.

[Second Embodiment] Next, a second embodiment of the present invention will be described.
An embodiment will be described.

In the method of the first embodiment, the encoding service provider C performs an encoding process for creating an encoded image for confirmation (step S402 in FIG. 1) and actually performs mass production printing on a printing press. Encoding processing for creating a coded image for printing (step S410 in FIG. 1). Therefore, in the authoring encoding system according to the second embodiment, when the first encoding process, that is, the encoding process for confirmation is performed, the digital data resulting from the encoding process is encoded in the form of intermediate data. The encoded image data created from the data subjected to the encoding process is stored in association with the encoded image data for printing, and when the encoded image for printing is created, the encoded image data is created using the stored intermediate data, whereby the second encoding is performed. It is possible to omit the processing, that is, the encoding processing for creating the encoded image for printing. As a result, the time required for the encoding process can be reduced, and the cost for the encoding process can be reduced.

Hereinafter, the flow of the encoding operation according to the present embodiment will be described with reference to FIG. 3A, focusing on the differences from the first embodiment.

First, as a process corresponding to the encoding process in step S402, an encoding process for creating a confirmation code is performed (step S601). Then, similarly to the confirmation encoded image generation processing in step S403, a confirmation encoded image is created based on the encoded data resulting from the encoding processing in step S601 (step S602). At this time, in the present embodiment, the encoded data created in the previous stage (step S601) used for the generation of the encoded image data for confirmation is used as intermediate data for the encoded image data created for confirmation. It is stored in association with the encoded image data.

The intermediate data in this case is shown in FIG.
Like the data processed in step S505,
Processing such as data compression and error correction coding has been performed,
The data has not been subjected to image data conversion processing. The method of associating the encoded image data with the intermediate data is shown in FIG.
(A), as a header data of encoded image data, a method of storing the header data together in one file,
As shown in FIG. 4B, a method is considered in which the coded image data is provided with link information and the intermediate data is stored at the link destination. Here, in addition to the intermediate data which is encoded data, the original binary encoded audio data, the encoding parameter setting information set at the time of performing the encoding process, and the like are also shown in FIG. Alternatively, as shown in (B), the information may be stored in association with each other.

The advantage of FIG. 4A is that the encoded image data and the intermediate data are surely associated with each other, and the advantage of FIG. 4B is that only the encoded image data is required. In such a case, only encoded image data can be easily taken out, unnecessary data such as unnecessary intermediate data can be omitted, and the data amount can be reduced.

By holding the intermediate data together with the generated encoded image data for confirmation in this way, the sound quality check is OK by the confirmation data on which the encoded image for confirmation is printed, and the encoded image for printing is created. Is issued, in the case of the above-described first embodiment, the encoding process (step S410) is performed again, and the encoded image for printing is generated based on the encoded data created there (step S410). S
411) In contrast to this, according to the present embodiment, when an instruction to create a coded image for printing is received, the code for printing is immediately generated based on the intermediate data stored in association with the coded image data for confirmation. A coded image can be generated (step S603).

The process of generating the encoded image for printing in step S603 may be performed simultaneously with the process of generating the encoded image for confirmation in step S602. Generate encoded image data for printing together with the code for confirmation in advance,
When the sound quality check by the confirmation code is OK and the print encoded image creation instruction is received, the print encoded image data that has been created in advance is extracted and passed, and the result is OK.

Further, the intermediate data, which is encoded data, has a very small data capacity as compared with the encoded image data having a large data capacity, so that it is convenient for data transfer. FIG. 3B shows an example in which only intermediate data according to the present embodiment is used when the encoded image data for printing is transferred from the encoding service provider C to the printing company A in the first embodiment. Shown.

That is, when the encoding service company C receives an instruction to create a coded image for printing from the publisher B, the encoding process (step S41) is performed in the first embodiment.
0), and then performs a print encoded image generation process (step S411). However, when the intermediate data according to the second embodiment is created, the encoding process becomes unnecessary. Thus, the encoding service provider C passes only the intermediate data that is the encoded data (only the right data portion of the link (B) in FIG. 4) to the printing company A. Here, the intermediate data requires a small data capacity as described above.
It becomes easy to use communication means such as a network for data transfer. When data is transferred by communication, it is desirable to add data such as a parity and a checksum in order to find or prevent data omission or garbled during communication.

The printing company A that has received the intermediate data by means of communication or the like generates an encoded image for printing from the received intermediate data (step S901). Then, the generated coded image data is laid out by DTP together with other characters, pictures, photographic data, and the like (step S902), and proof printing is performed (step S9).
Subsequent processes such as 03) are completely the same as in the first embodiment. As described above, by using the intermediate data itself for data transfer, time and cost for data transfer can be reduced.

As described above, in the present embodiment, by saving the intermediate data as a result of performing the encoding process, the encoding process can be reduced, and the man-hour and cost for the encoding process can be reduced. Can be.
