Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an information processing method and apparatus, and particularly to a code 1
The present invention relates to a method for reading and decoding recorded information, and a processing device directly used for carrying out the method.

[Conventional technology]

As a method for mechanically and automatically processing the information to be transmitted,
Broadly speaking, there are two methods: one is to read and process original data such as character codes as is, and the other is to encode and display the transmitted information and then read and process the code.

An example of reading the former source data as is is 0CR.
Typical examples include (optical character reader) and OMR (optical code reader).

A typical example of reading the latter code is using a bar code. Also recently, “Ten noji”.

There are known examples of using code of the form.

[Invention or problem to be solved]

When information is processed by the above-mentioned OCR or the like, it is advantageous in that the original data can be used as is without the need to convert it into a -1 code. However, the display format of the original data varies, and even in the case of machine printing, there are differences in font and shading, and in the case of handwritten characters, many deformed characters appear, making it difficult to prevent reading errors. There is a limit. Therefore, it is necessary to standardize the font, and a dedicated writer is also required.

On the other hand, when a barcode is used, the barcode itself is a machine-printed bar arrangement, so the incidence of reading errors due to the diversity of the original data is extremely low. but,
Barcodes are displayed with each bar having a different thickness and spacing, so they require highly accurate printing technology.
It takes time and money. Furthermore, barcodes are difficult to read by humans and require a dedicated reading device, and on the other hand, handwritten display is almost impossible.

SUMMARY OF THE INVENTION An object of the present invention is to provide an information processing method and apparatus that can accurately display and read even handwritten information and process information with relatively simple handling.

[Means to solve the problem]

In order to solve the above-mentioned conventional problems and achieve the object of the present invention, the first invention of the present application is such that information to be transmitted is converted into a display format different from the display format of the transmitted information in a certain correspondence relationship. In an information processing method in which a display code displayed on a display medium is read and decoded by a reading device, the display code is composed of unit code components (2 to 6) displayed within a rectangular display area (1) or The unit code component includes a reference mark element (2) arranged at one corner of the display area, a reference mark element (2) arranged at one corner of the display area, and a reference mark element (2) parallel to the side of the display area. It is configured by line segment elements (3, 4), diagonal line segment elements (5, 6) in the display area, or a combination thereof, and transmits the configuration pattern of the display code based on the read signal of the display code. This method is characterized in that the decoding process is performed by comparing and collating a predefined dictionary pattern corresponding to the # information.

Further, the second invention of the present application provides information in which the information to be transmitted is converted into a display format different from the display format of the transmitted information in a certain correspondence relationship, and a display code displayed on a predetermined display medium is read and decoded. In the processing device, the code is configured by a unit code component displayed in a rectangular display area or a combination arrangement of the unit code components, and the unit code component is located at any one corner of the display area. It is composed of a reference mark element arranged at a corner, a line segment element parallel to the side of the display area, a diagonal line segment element in the display area, or a combination thereof, and the information processing device reads the display code. A reading means (101) for converting into an electrical signal, a dictionary pattern memory (106) in which a dictionary pattern corresponding to the configuration pattern of the unit code component is stored in advance, and comparing and collating the read signal and the dictionary pattern. It is characterized by comprising a decoding means (105) for decoding.

[Effect]

According to the invention of this illumination 1, the information to be transmitted is displayed via a display code having a unique form according to the present invention, and when reading and processing this display code, advanced printing technology is required. The simple format allows information to be transmitted with an extremely low error rate.

This is because the display code is expressed by a combination of the reference mark in the display area and the presence or absence of line segment elements in the display area, and has a relatively simple configuration.

According to the present invention, the display code is read by the reading means, and the contents of the code are decoded by comparison with a dictionary pattern prepared in advance.

In this case, since the display code has a simple configuration, there is no need for a complicated device configuration, and since the signals to be processed are not complex, the processing speed is improved and high-speed information transmission is possible.

〔Example〕

Next, examples of the present irradiation temperature 1 and the second invention will be described based on the drawings.

Display Code First, the display code to be processed by the present invention will be explained.

Figure 1 shows the basic structure of the display code. This display code is composed of unit code components displayed within the rectangular display area 1 or a combination arrangement of the unit code components.

The unit code components include a reference mark element (hereinafter referred to as a neutral mark) 2 placed at one corner of the display area 1, and line segments parallel to each side of the display area 1. elements (hereinafter referred to as vertical line 3 and horizontal line 4).

) and diagonal line segment elements in display area 1 (hereinafter, the upward-right diagonal line is referred to as right diagonal line 5, and the upward-left diagonal line is referred to as left diagonal line 6).
There is something like that. These are neutral mark 2, vertical line 3,
It is expressed by a combination of a horizontal line 4, a right diagonal line 5, or a left diagonal line 6, or a combination thereof.

The neutral mark 2 indicates the reference position in the scanning direction when reading the display code, and at the same time indicates the boundary between a plurality of unit code components.0For example, as shown in FIG. If scanning in the right direction based on the position, scan in the direction of the arrow in Figure 2 (a), and if scanning in the opposite direction to the left, scan in the direction of the arrow in Figure 2 (b).
The directionality can be specified even when scanning in any direction, such as downward scanning in Figure 2 (C) and upward scanning in Figure 2 (d). I can do it. Therefore, when a plurality of unit code components are arranged, they can be arranged in a correct order.

Furthermore, when a plurality of neutral marks 2 are arranged in this way, the neutral marks 2 indicate the boundaries between adjacent unit code components, so for example, as shown in FIG. It can be detected that the unit code component currently being read is being read until the next neutral mark appears. That is, the spacing between each element can be made clear. This can prevent reading errors between adjacent unit code components.

There are four basic combinations of unit code components, as shown in FIG. One is when there is only neutral mark 2 as shown in Fig. 3(a), the next is when there is a combination of neutral mark 2 and Mi line 3 or horizontal line 4 as shown in Fig. 3(b), and the next is when there is only neutral mark 2 as shown in Fig. 3(b). In the case of a combination of neutral mark 2 and right diagonal line 5 or left diagonal line 6 as shown in figure (C),
Next, as shown in Figure 3(d), the neutral mark 2, vertical line 3 or horizontal line 4, and right diagonal line 5 or left diagonal line 6
This is the case in combination with

The above unit code components are neutral mark 2,
By giving a meaning to each of the vertical line 3, horizontal line 4, right diagonal line 5, and left diagonal line 6, it is possible to give it a meaning by itself. However, since there is a limit to the amount of information that can be transmitted using only one unit code component, the amount of information that can be transmitted can be increased by combining a plurality of unit code components and arranging them in a certain direction.

Here, FIG. 4 shows the definition of each unit code component. In this example, each unit code component is defined using a hexadecimal code. Since each corresponding quantity 1 system can be understood from this FIG. 4, the explanation will be omitted. The maximum value "F" that can be expressed by the above unit code component is "15'° in decimal notation, and since the configuration pattern at this time is similar to "°umbrella", this is the representation used in the present invention. The code is called the “umbrella mark code”°.

Next, FIG. 5 shows an example of a combination of the above unit code components. The example in Figure 5 is the hexadecimal code °“258 F
” is shown.

The above display codes are displayed on various display media such as forms and product caps. The display method or display mode may be a so-called direct notation method such as handwriting or handwritten machine printing using a mark sheet, a method using magnetic coating that magnetizes only the unit component part, or a stamp or raised dot on the display medium. One possible method is to do this.

Which one to use is appropriately selected depending on the place of use, purpose of use, display medium, etc. In addition, the size should be such that it can be distinguished, and it can be used selectively when checking with the naked eye or depending on the resolution of the reading device, but -
Considering the case where it is used for boat fishing, it is preferable to standardize it.

Kyousou Kasa 1 Next, an understanding device for reading and processing the above display code will be explained. FIG. 6 shows an example of the processing device. This example shows an example in which a display code printed on a form 100 is optically read, and is a non-contact reading type.

In FIG. 6, a photoelectric conversion unit 101 optically reads a display code written on a form 1, OO.

Specifically, a scanner using a one-dimensional or two-dimensional image sensor (for example, a CCD image sensor, etc.)
(including hand scanners) can be used. This photoelectric conversion unit 101 reads an optical signal (
video signal) to an electrical signal and outputs it. This video signal is sent to the next binarization section 102.

Since the video signal is an analog signal, the binarization unit 102 converts it into a binary signal of logic “1 pass, 0” for computer processing.The disulfurized display code pattern signal is sent to the cutting unit 103. sent to.

The cutout unit 103 extracts the display code pattern signal pattern by pattern, that is, each unit code component, 1.2 in FIG.
・This is a circuit that facilitates recognition processing by cutting out each F). The extracted pattern signal is sent to normalization section 104.

The normalization unit 104 removes dirt, ie, noise, contained in the extracted pattern signal, and performs alignment necessary when comparing the pattern signal with a dictionary pattern to be described later. The normalized pattern signal is sent to the recognition unit 10
Sent to 5.

The recognition unit 105 compares and matches the normalized pattern signal with the dictionary pattern signal from the dictionary pattern memory 106 and determines the degree of similarity, thereby recognizing or decoding the input normalized pattern signal. .

゛ The dictionary pattern memory 106 contains dictionary patterns (1, 2, 3...F) defined in advance in FIG.
The dictionary pattern is stored therein, and the corresponding dictionary pattern is output in response to a read control command from the recognition unit 105.

The result recognized by the recognition unit 105 is outputted to the outside by the output unit 107. The external output is the post-processing unit 108
and is converted into the original data, which is the display code, in its unconverted state. For example, the display code in Figure 5 is "258F" in hexadecimal code and "61F" in decimal code.
．． 570", or if this were to represent the product number, it would be output at the required level. In other words, it would be output as a hexadecimal code,
The data can be transferred to a music aggregation device or displayed in the form of a product number on a CRT display.

The above processing device is not dedicated to the display code used in the present invention, but can be configured using existing OCR or OMR. In that case, OCR or OMR
This can be realized by registering the storage pattern of the dictionary pattern memory in place of the display code pattern according to the present invention. By making the dictionary pattern memory replaceable as an IC memory as appropriate, it becomes possible to use it in combination with general-purpose OCR and OMR.

In the example of Nijitan Inuri Shui-F, the display code is printed by a machine, and an example of optically reading the code without contact has been described, but other embodiments are listed as follows. .

As a first example, each element of the unit code component of the display code, that is, neutral mark 2, vertical line 3, horizontal line 4
, the right diagonal line 5 and the left diagonal line 6 may be magnetized by magnetic coating and read by a read magnetic head. In this case, the configuration after the binarization section 102 may be the same as that shown in FIG. According to this first example, when displaying (magnetic writing) a display code on a display medium, the write head basically has the same configuration as the read head, and 1
It has the advantage of being able to perform both recording and playback with one machine.

As a second example, the display code may be engraved or embossed instead of being printed, and then read optically.

As a third example, the definition shown in Figure 6 sets the display code to 1.
It may correspond to a hexadecimal code, or it may be defined using a 64-decimal code in order to correspond to more complex and large amounts of information. An example is shown in FIG.

The basic structure of the display code is the same as that shown in FIG. 6, and consists of a combination of a neutral mark and each line segment element. however,
There are a total of six line segment elements, including line segments that are not used in the case of hexadecimal codes2, allowing for a variety of expressions. This can be easily understood from FIG.

〔Effect of the invention〕

As described above, according to the present invention, since the display code of a so-called full mark is used to transmit and process information, there is no need for high-precision printing technology such as barcodes, and accurate printing is possible. Information transmission processing is possible. Further, since the display code of the medium mark has a simple configuration, it can also be read manually.

Further, the information processing device according to the present invention can be configured relatively easily due to the simple form of the display code of the umbrella mark, and it is possible to maintain a high level of reading accuracy. Become.
