Description

Barcode instruction generator

The present invention relates to a technique for displaying a barcode image with high reading accuracy on a display such as a terminal device.

Conventionally, when paying usage fees for electricity, water, gas, etc., payment was made by presenting a payment slip printed with a barcode to a convenience store. However, in recent years, it has been attempted to make such payment by presenting a barcode displayed on a display such as a mobile phone.

Japanese Patent Laid-Open No. 2003-115025

However, it is very difficult to read a barcode displayed on the display at a reading rate close to 100%.

Therefore, the present inventor does not have a problem in the way of development so far, such as creating an instruction for displaying the barcode on the display using a format common to the instruction for printing the barcode. I thought.

When I examined this, it was true. Specifically, in the print command for printing the barcode on the paper, the width of the bar is defined by the unit of “point (pt)”, and the command for displaying on the display using this point is given. There was a problem in that it was generated.

This point is a unit for determining the size of characters when printing with a printer, and is defined as a length of 1/72 inch (about 0.35 mm). That is, in the print command, the width of the bar is defined in units of points such as “1 point” and “2 points”.

On the other hand, the display is composed of “pixels”. For example, if the display is “326 PPI (Pixel Per Inch)”, 1 pixel is 0.077 mm. When points are used in the display command for such a display, the width of “1 point” is “0.35 ÷ 0.077 = 4.545 pixels”. However, since it is not possible to perform pixel control below the decimal point, a device including a display rounds up or down the decimal point such as “5 pixels” or “4 pixels” as a width to be displayed for such a display command. Truncate and interpret and execute. Then, the barcode displayed as a result of such interpretation and execution will be transformed from the original barcode, and the information that the barcode should show cannot be read accurately. is there.

In order to solve the above-described problems, the present invention provides the following barcode command generation device. That is, as a first invention, a content information acquisition unit that acquires content information to be indicated by a barcode, and a barcode definition within a range in which each bar constituting the barcode from the acquired content information can be read and calculated by the reading device A print command generation unit that generates a print command using the print width unit of the printing device so as to achieve a specified print width ratio, and a range in which each bar constituting the barcode can be read and calculated by the reading device from the acquired content information And a display command generation unit that generates a display display command using a display display width unit of the display device so as to have a display definition width ratio defined by the barcode definition.

<Embodiment 1>
<Overview>

The barcode command generation device of the present embodiment generates a barcode printing command from content information to be indicated by the barcode, and generates a display display command for displaying the barcode on the display.
<Configuration>

FIG. 1 is a diagram showing an example of functional blocks in the barcode command generation device of this embodiment. Note that functional blocks of the apparatus and system described below can be realized as a combination of hardware and software. Specifically, if a computer is used, a CPU, a main memory, a bus, or a secondary storage device (a hard disk, a non-volatile memory, a storage medium such as a CD or a DVD, a read drive for the medium, etc.), information Input devices used for input, printing equipment, display devices, other hardware components such as external peripheral devices, interfaces for external peripheral devices, communication interfaces, driver programs for controlling these hardware, Other examples include application programs and user interface applications. Then, by CPU processing according to the program developed on the main memory, the data input from the input device or other interface and held in the memory or hard disk is processed and stored, An instruction for controlling the software is generated. Alternatively, the functional blocks of this system may be realized by dedicated hardware.

Each embodiment described in the present specification can be realized not only as an apparatus but also as a method. Moreover, a part of such an apparatus can be configured as software. Furthermore, a software product used to cause a computer to execute such software and a recording medium on which the product is fixed are naturally included in the technical scope of each embodiment described in this specification (this specification The same throughout.)

As shown in FIG. 1, the “barcode command generation device” (0100) of this embodiment includes a “content information acquisition unit” (0101), a “print command generation unit” (0102), and a “display”. Display command generation unit "(0103).

The “content information acquisition unit” (0101) has a function of acquiring content information to be indicated by a barcode.

“Content information” is, for example, “payers”, “usage charges”, “payment due dates” that are various information included in payment slips, etc., and “product name” that is various information included in the product display , “Price”, “expiration date”, “manufacturer”, “producer information”, and the like. Acquisition of content information is performed via an Internet line, a telephone line, near field communication, an optical reader, or the like. The acquired content information may be stored in a non-volatile storage device such as a flash memory, or may be configured to be temporarily stored in a volatile storage device such as a ROM.

The “print command generating unit” (0102) prints the printing width of the printing apparatus so that each bar constituting the barcode from the acquired content information has a barcode width stipulated in the barcode definition within a range that can be read and calculated by the reading apparatus. It has a function of generating a print command using a unit.

"Barcode definition" is a definition defined by various barcode standards. Information such as the characters and modules that make up a barcode and the dimensions of the minimum element are shown as barcodes and can be read. There are various definitions for this. There are various bar code standards, such as JAN code, CODE39, CODE128, NW-7, ITF, and GS1-128. Among them, CODE39, NW-7, and ITF are called binary codes, and characters (alphabet, numbers, symbols, etc.) are composed of a combination of two types of bars and spaces, thin and thick. The JAN code, CODE128, and GS1-128 are called multi-level codes, and form a character by a combination of more than two kinds of thickness bars and spaces.

“Becomes the printing width ratio specified by the barcode definition within the range that can be read by the reading device” means not only when the printed barcode exactly matches the printing width ratio specified by the barcode definition. This means that the reading device has a print width ratio that includes an error within an allowable range that can be determined as the definition of the barcode.

“The printing width ratio defined in the barcode definition” means the ratio of the width of each bar or space constituting the barcode when the barcode is printed. If the printed barcode does not conform to this print width ratio, it cannot be read as a barcode according to the standard having the barcode definition.

For example, in the CODE 39 described above, the width of the thick bar is set to 2.3 to 3.0 times the width of the thin bar, and the same applies to the space. Therefore, in order to print a CODE39 standard barcode so that it can be read by a reader, the width ratio of the thin bar and the thick bar (thin space and thick space) is 1: 2.3 to 3.0. It must be printed as

Also, the CODE128 standard uses four types of bars with widths of 2 times, 3 times and 4 times based on the thinnest bar. Therefore, the print width ratio in this standard is 1: 2: 3: 4. Similarly, the width between the bars is 1: 2: 3: 4.

The “print command” is a command for causing the printing apparatus to print a barcode or the like on a sheet or the like. For example, a command using a general-purpose document creation application or a drawing application, a dedicated program corresponding to a printing apparatus or printed matter, and the like.

This print command is created using the print width unit of the printing device. The print width unit is a unit for defining the size of a character to be printed, the thickness of a line, and the like, and includes, for example, “point (pt)”. Such print instructions can be generated by conventional techniques for printing barcodes on paper.

When “point (pt)” is used as a printing width unit, the width of the thinnest bar serving as a reference is “1 point” and the remaining three types of bar widths are “2 points” and “3”, respectively. Print commands are generated as “points” and “4 points”. By printing according to the print command generated in this way, the barcode is printed according to the print width ratio defined by the CODE 128, so that reading is performed by the reader without error.

The “display display command generation unit” (0103) is configured so that each bar constituting the barcode from the acquired content information has a display display width ratio stipulated by the barcode definition within a range that can be read and calculated by the reading device. It has a function of generating a display display command using a display display width unit. “Becomes the display display width ratio defined by the barcode definition within the range in which the reading operation of the reading device can be performed” has the same meaning as in the print command.

The display display width unit refers to, for example, “pixel” which is a unit for composing an image on a display. The display display command generation unit generates a display display command so that the display definition width ratio defined by the barcode definition is obtained in units of such pixels.

For example, in the case of generating a display command for displaying a bar code defined by CODE128, the ratio of the widths of the bars is “1: 2: 3: 4”. Here, when the PPI (Pixel Per Inch) of the display is “326 PPI”, one pixel is 0.077 mm. On the other hand, according to the CODE128 standard, it is recommended that the width of the smallest element (width of the thinnest bar) is 0.191 mm or more. Therefore, in order to satisfy this rule, the bar code is displayed with the minimum element width of “3 pixels = 0.231 mm” and the ratio of the widths of the four types of bars as “3 pixels: 6 pixels: 9 pixels: 12 pixels”. Generate instructions.

Also, taking CODE39 as an example, the minimum element width in this case is recommended to be 0.191 mm or more. Therefore, the width of the thin bar constituting CODE 39 is 3 pixels, and the width of the thick bar is 2.3 to 3.0 times the width of the thin bar. Therefore, either 7 pixels, 8 pixels, or 9 pixels are used. can do. Then, the barcode display command is generated with the ratio of the width of the thin bar to the width of the thick bar being, for example, “3 pixels: 8 pixels”.

Note that the space between the bars is displayed on the display by drawing a bar such as white that can be compared with the black bar. Therefore, in this specification, such a space may be expressed using the term “white bar”.

FIG. 2 is a conceptual diagram showing an example of a barcode displayed by the generated display display command. The barcode shown in the figure is based on the CODE128 standard. FIG. 2A shows the entire displayed barcode. FIG. 2B is a conceptual diagram showing the ratio of the widths of the bars constituting the barcode for a part of the barcode shown in FIG. Note that the outline of the white bar is given for convenience of explanation. FIG. 2C is a conceptual diagram showing a part of the barcode shown in FIG. 2B in units of display pixels. Note that the drawing of RGB subpixels is merely omitted, and does not indicate that the drawing is a monochrome display.

As described above, the display width ratio of the black bar and the white bar constituting the CODE128-defined bar code is “1: 2: 3: 4”. For each width, “thinnest: slightly thin: slightly thick”. : "The thickest". Further, in order to satisfy the definition of the recommended width of the minimum element, the width of the thinnest bar is set to “3 pixels”.

In FIG. 2 (a), the bars constituting the portion surrounded by the broken lines are “slightly black bar”, “slightly white bar”, “slightly thick black bar”, “thinnest white bar”, “most fine bar” from the left. It is a “thin black bar”. When these bars are represented by the display width ratio specified by the above bar code, as shown in FIG. 2B, “black 2: white 2: black 3: white 1: black 1” from the left.

As described above, since the width of the thinnest bar is “3 pixels”, when it is expressed on the display based on the width ratio of FIG. 2B, as shown in FIG. To “black 6: white 6: black 9: white 3: black 3”. In this way, by using the pixels of the display as a unit and constructing the barcode with the ratio of the width satisfying the barcode definition rule, it is possible to eliminate the possibility of erroneous reading or unreadable.

Some bar code readers allow a certain amount of error in determining whether the width of the read bar conforms to a predetermined bar code rule. Therefore, in the generation of the barcode display command, instead of demarcating the width of the bar to be displayed in advance based on the barcode specification or the PPI of the display as described above, the value after the decimal point is generated by converting the width in pixels. You may comprise so that the display command which displays a barcode may be produced | generated by controlling whether it rounds up or down. For example, it may be configured to control by rounding off or rounding up the value after the decimal point, or by setting a predetermined condition so as to round up or down according to the value after the decimal point. In the latter control, for example, the condition for rounding down is “0.3 or less”, and the condition for rounding up is “0.7 or more”. If a value below the decimal point that does not meet any of the conditions occurs, it may be configured not to be read, or to try to generate a display display command by another method described above or described later. .

As described with reference to FIG. 2, the width of each bar is defined in units of pixels, and the display display command for displaying the barcode is generated based on the definition. There are also orders.

For example, it is possible to generate a display command for displaying a barcode by using a bar whose width is defined by “point” and drawing the bar by superimposing the drawing position while appropriately moving the drawing position.

As already described, the width of one point is 4.545 pixels in the case of 326 PPI, and a conventional command draws a bar with a width of “5 pixels” by rounding up. However, even in such a command, the coordinates for specifying the start point and the end point to be drawn may be defined by pixels. Thus, by using a bar having a width of 5 pixels and drawing it while overlapping the drawing position of the bar in the horizontal direction as appropriate, the barcode can be displayed with a width ratio defined by the barcode definition.

FIG. 3 is a conceptual diagram for explaining a display command by the above method. In this example, a bar code “black 6: white 6: black 3: white 3: black 3” is displayed. As shown in FIG. 3A, using a black bar and a white bar having a width of 5 pixels, the start points are sequentially superimposed and drawn in the right direction by 3 pixels. Specifically, first, the black bar is shifted and drawn twice, and then the white bar is shifted and drawn twice. Then, the black bar is drawn once, the white bar is drawn once, and the black bar is drawn once. The last drawn white bar is drawn in order to define the width of the black bar drawn before that. When the drawing is performed by shifting the starting point by 3 pixels in this way, a bar code of “black 6: white 6: black 3: white 3: black 3” is displayed as shown in FIG. 3B. . In actual display, since the outline of the white bar does not exist, a barcode as shown in FIG. 3C is displayed. By drawing in this way, even if the bar width is defined based on the print command, such as points or millimeters, the barcode can be converted without converting the width into pixels. The display can be performed at a specified width ratio of each bar, and an increase in the processing load of the apparatus that displays the barcode may be suppressed.

In this example, since the case where the minimum pixel for satisfying the minimum element width defined by the barcode is 3 pixels is used, the amount by which the start point is shifted is 3 pixels. However, the amount to be shifted may be changed as appropriate according to the PPI of the display to be displayed, the definition of the minimum element width of the barcode to be displayed, and the like.
<Hardware>

FIG. 4 is a schematic diagram showing an example of the configuration of the barcode command generation device when the above functional components are realized as hardware. The operation of each hardware configuration will be described using this figure.

As shown in the figure, the bar code instruction generation device reads a “CPU” (0401) for executing various arithmetic processes and a program for performing various arithmetic processes for execution by the CPU and provides a work area for the program. A “main memory” (0402). With these configurations, a content information acquisition unit, a print command generation unit, and a display display command generation unit are implemented. Also, a storage device such as “HDD” (0403) for holding the acquired content information, various bar code definition rules, information indicating the PPI of the display device, a generated print command, a display display command, etc. A “communication circuit” (0404) for outputting a print command, a display display command, and the like to a device, a display device, and the like via a network is also provided. Then, they are connected to each other via a data communication path such as a system bus (0405) to perform transmission / reception and processing of information.

First, the CPU expands the content information acquisition program stored in the HDD in the work area of the main memory, executes it, and acquires the content information via a communication circuit. Then, the CPU executes the print command generation program, acquires the barcode type from the content information, and reads the barcode width defined by the barcode definition corresponding to the type. And the process which produces | generates the printing command using printing width units, such as a point, is performed. The generated print command is stored in the storage area of the main memory or the HDD.

Also, the CPU executes the display display command generation program, acquires the barcode type from the content information, and reads the barcode width defined in the barcode definition corresponding to the type. And the process which produces | generates a display display command using the pixel which is a display display width unit is performed. The generated display display command is stored in the storage area of the main memory or the HDD.

When the CPU receives a print command or display display command output request via the communication circuit, the CPU executes an output program for outputting the stored print command or display display command. A process of outputting the display command via the communication circuit is executed.
<Process flow>

FIG. 5 is a flowchart showing an example of the flow of processing in the barcode command generation device of this embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. It does not matter (the same applies to Embodiment 2 and later described later).

As shown in the drawing, first, content information to be indicated by a barcode is acquired (content information acquisition step: S0501). Then, a printing command using a printing width unit of the printing apparatus is generated from the acquired content information so that each bar constituting the barcode has a printing width ratio defined in the barcode definition within a range in which the reading apparatus can perform reading calculation. (Print command generation step: S0502). Then, a display display instruction using the display display width unit of the display device so that each bar constituting the barcode from the acquired content information has a display display width ratio defined by the barcode definition within a range in which the reading device can perform a read operation. (Display display command generation step: S0503). Note that the order of the print command generation step and the display display command generation step may be reversed.
<Effect>

The barcode command generation device according to the present embodiment generates a command for printing a barcode indicating the information from the information to be indicated by the barcode, and displays a barcode with high reading accuracy on the display. An instruction can be generated.
<Embodiment 2>
<Overview>

The barcode command conversion device according to the present embodiment displays a barcode by maintaining a bar or space width defined by a predetermined barcode definition from a print command for printing a barcode on a printing device. Convert to display instructions for display.

The current status of bar code use is mostly printed on paper. Under such circumstances, instead of generating both a print command and a display display command from the content information to be indicated by the bar code, a print command is mainly generated, and the bar code is displayed from the generated print command as necessary. It is also considered necessary to be able to convert it into a command for display on the screen. Here, when converting from a print command to a command for display on a display, attention must be paid to the following points.

The width specification in the print command for printing the barcode on paper is performed using a unit of “point”, for example. This point is a unit for determining the character size and the like when printing by the printer, and is defined as a length of 1/72 inch. That is, in the print command, the width of the bar is defined in units of points such as “1 point” and “2 points”. For example, since the bar width ratio in the CODE128 standard is “1: 2: 3: 4”, the barcode is printed as “1 point: 2 points: 3 points: 4 points” accordingly. Since 1 point = 0.35 mm, the minimum element width is satisfied.

In order to generate a command for displaying a barcode from such a print command, it is necessary to change the coordinates and width to information for defining on the display. Therefore, a display command is generated in units of pixels constituting the display. For example, there is a “LINE statement” as a command statement for drawing a line or the like on the display. This statement is configured by defining the starting point and ending point of drawing and the line width in units of pixels. A print command is applied to this command statement. It is relatively easy to replace the start point and end point coordinates with the coordinates on the display. On the other hand, it is not easy to replace the width because the length of “point”, which is the unit on the paper, is different from the length of “pixel”, which is the unit on the display.

That is, the width of the bar code defined as “1 point” is 1/72 inch and about 0.35 mm. If this 1 point is replaced with a pixel, for example, in the case of a display of “326 PPI (Pixel Per Inch)”, since 1 pixel = 0.077 mm, 1 point = 4.54 pixels. Similarly, 2 points = 9.09 pixels, 3 points = 13.63 pixels, and 4 points = 18.18 pixels. When such an instruction including a value after the decimal point is generated, it is impossible to display the pixel after the decimal point on the display. Therefore, the display device including the display raises or lowers the decimal point to an integer. It is displayed again according to the rule by value.

However, if the relationship between the above points and pixels is lowered and revised, it becomes “4: 9: 13: 18”, and does not become “1: 2: 3: 4” defined by CODE128. Moreover, when it is advanced and revised, it becomes “5: 10: 14: 19”, and this does not become “1: 2: 3: 4”. In either case, the bar / space width ratio does not comply with the regulations, and the bar code displayed by such a display command is not read and an error occurs.

Therefore, in the barcode command generation device of the present embodiment, the barcode is displayed from the print command so that the bar or space width defined by the predetermined barcode definition is maintained in units of pixels. Convert to display instruction.
<Configuration>

FIG. 6 is a diagram showing an example of functional blocks in the barcode command conversion device of the present embodiment. As illustrated, the “barcode command conversion device” (0600) includes a “print command acquisition unit” (0601) and a “print command conversion unit” (0602). The definitions used in the present embodiment are basically the same as the definitions of the same name in the first embodiment.

The “print command acquisition unit” has a function of acquiring a print command configured by using the print width unit of the printing apparatus so that the print width ratio specified by the barcode definition is obtained. This “print command” is the same as the print command generated by the print command generation unit in the first embodiment. Therefore, the description of the “print command” is omitted. For example, the print command acquisition unit acquires a “print command” from the barcode command generation device according to the first embodiment.

The “print command conversion unit” is a display display width unit of the display device so that each bar constituting the barcode from the acquired print command has a display display width ratio defined by the barcode definition within a range in which the reading device can perform a read operation. It has a function of converting to a display display command using. This “display display command” is the same as the display display command generated by the display display command generation unit in the first embodiment. Therefore, the description of the “display display command” is omitted.

The conversion from the print command to the display display command is performed by converting the print width ratio of the acquired print command into the display display width ratio. For example, as described above, when a print command configured with “1: 2: 3: 4” as the print width ratio of each bar and each space constituting the barcode with “point” as a unit is acquired, The print width ratio is converted into a display width ratio in units of “pixels”.

For example, when converting to the display display width ratio for displaying CODE 128 standard barcode on the “326PPI” display, the print width ratio of “1: 2: 3: 4” with the point as a unit is converted into the pixel unit as it is. Then, “4.54: 9.09: 13.63: 18.18” is obtained, which does not conform to the specified width ratio. For example, “4: 8: 12: 16” or “5:10: 15:20 ". Whether the former or the latter is used, for example, the recommended minimum element width value, the size of the display surface of the display to be displayed, and the terminal equipped with the display to be displayed can change the display direction vertically and horizontally It can be appropriately selected depending on whether or not. A print command is converted into a display display command based on the display width ratio thus converted.

The display display command based on the converted display width ratio is the same as the display display command in the first embodiment. For example, based on the width ratio such as “4: 8: 12: 16”, each bar code width to be displayed is defined in units of pixels and configured to be displayed on the display, or rounded up based on points. A bar having a width of “5 pixels” may be superimposed and drawn while sequentially shifting the start point.
<Hardware>

FIG. 7 is a schematic diagram showing an example of the configuration of the barcode command conversion device when the above functional components are realized as hardware. The operation of each hardware configuration will be described using this figure.

As shown in the figure, the bar code instruction conversion device reads out “CPU” (0701) for executing various arithmetic processes and a program for performing various arithmetic processes for execution by the CPU and provides a work area for the program. A “main memory” (0702). With these configurations, a print command acquisition unit and a print command conversion unit are implemented. In addition, a storage device such as “HDD” (0703) for holding acquired print commands, width ratios of various barcode definition stipulated information, information indicating the PPI of the display device, converted display display commands, etc., and printing A “communication circuit” (0704) for outputting a display display command converted to a device or a display device via a network is also provided. Then, they are connected to each other via a data communication path such as a system bus (0705) to transmit / receive information and process information.

First, the CPU develops a print command acquisition program held in the HDD in the work area of the main memory, executes it, and acquires a print command via a communication circuit. Then, the CPU executes a print command conversion program and executes processing for converting print information into a display display command. Then, the converted display display command is stored in the storage area of the main memory or the HDD.
<Process flow>

FIG. 8 is a flowchart showing an example of the flow of processing in the barcode command conversion device of this embodiment. As shown in the figure, first, a print command configured using the print width unit of the printing apparatus so as to obtain the print width ratio defined by the barcode definition is acquired (print command acquisition step: S0801). Then, a display display instruction using the display display width unit of the display device so that each bar constituting the barcode from the acquired print command has a display display width ratio defined by the barcode definition within a range in which the reading operation of the reading device can be performed. (Print command conversion step: S0802).
<Effect>
