JP, 2017-121769, A

  When the image forming apparatus interprets PDL data and draws the drawing data to generate the drawing data, it is desirable not to generate garbled characters.

An image forming apparatus according to an embodiment of the present disclosure is
A storage device that stores fixed-part image data that is image data of a fixed part that does not depend on data to be printed,
By executing the image forming program,
A character code determination unit that acquires PDL data including the fixed unit and a variable value that depends on the data to be printed, and determines whether the PDL data is described by a specific character code.
When the PDL data is described with the specific character code, a data conversion unit that converts the PDL data into image data to generate conversion data,
Optical character recognition of the converted data, it is determined whether the fixed portion included in the converted data includes garbled, if the fixed portion includes garbled, whether the garbled is more than a threshold value And a garbled character determination unit that determines
When the PDL data is not described by the specific character code, or when the garbled characters are more than the threshold value, the fixed part image data is read from the storage device, and the variable value included in the PDL data is read. Interpretation and drawing to generate first drawing data, combining the fixed part image data and the first drawing data to generate first combined data, or when the garbled character is less than or equal to the threshold value Reading the fixed part image data of the garbled part from the storage device, interpreting and drawing the non-garbled part included in the fixed part of the PDL data and the variable value included in the PDL data. To generate second drawing data, and to combine the fixed part image data of the garbled part with the second drawing data to generate second combined data. Drawing section,
A control circuit that operates as a print control unit that outputs the first combined data or the second combined data to the image forming unit.

  According to the present embodiment, the character code determination unit acquires the PDL data including the fixed unit and the variable value that depends on the data to be printed, and determines whether the PDL data is described by the specific character code. to decide. As a result, it is possible to surely determine the case where garbled characters occur (PDL data is not described with a specific character code). Further, the garbled character determination unit performs optical character recognition on the converted data obtained by converting the PDL data into image data, and determines whether the fixed part included in the converted data contains garbled characters. As a result, even if the PDL data is described with a specific character code, it is possible to reliably determine the case where the garbled character occurs. Furthermore, when garbled characters are always generated (PDL data is not described in a specific character code) and when garbled characters are larger than the threshold value, the first portion is used by using the fixed part image data stored in advance in the storage device. Since synthetic data is generated, garbled characters cannot occur. Further, when the garbled character is less than or equal to the threshold value, only the garbled part is used to generate the second combined data by using the fixed part image data stored in advance in the storage device. The amount of data is also saved because the use of image data is minimized.

If the fixed unit does not include garbled characters, the drawing unit interprets and draws the PDL data to generate third drawing data,
The print control unit outputs the third drawing data to the image forming unit.

  According to this embodiment, when the fixed part does not include garbled characters, the drawing unit interprets and draws the PDL data to generate the third drawing data. As a result, if it is determined in advance that the garbled characters will not occur, the fixed part image data is not used, and the data amount is saved.

  The specific character code is Shift_JIS.

  When the image forming program interprets and draws the PDL data described and generated in a font that is not supported by the image forming apparatus, garbled characters occur. For example, PDL data can be generated with various character codes (Shift_JIS and other character codes). However, an image forming program that interprets and draws the PDL data cannot correctly interpret and draw unless the PDL data is described in a specific character code (Shift_JIS). Conversely, the image forming program interprets and draws the PDL data described by a character code other than the specific character code (Shift_JIS) (for example, a character code used to represent a character string including Chinese). Then, the characters are always garbled. On the other hand, according to the present embodiment, the PDL data described by a character code other than the specific character code (Shift_JIS) (for example, a character code used to represent a character string including Chinese) is It can be drawn without garbled characters.

An image forming program according to an embodiment of the present disclosure is
A control circuit of an image forming apparatus having a storage device that stores fixed part image data that is image data of a fixed part that is independent of print target data,
A character code determination unit that acquires PDL data including the fixed unit and a variable value that depends on the data to be printed, and determines whether the PDL data is described by a specific character code.
When the PDL data is described with the specific character code, a data conversion unit that converts the PDL data into image data to generate conversion data,
Optical character recognition of the converted data, it is determined whether the fixed portion included in the converted data includes garbled, if the fixed portion includes garbled, whether the garbled is more than a threshold value And a garbled character determination unit that determines
When the PDL data is not described by the specific character code, or when the garbled characters are more than the threshold value, the fixed part image data is read from the storage device, and the variable value included in the PDL data is read. Interpretation and drawing to generate first drawing data, combining the fixed part image data and the first drawing data to generate first combined data, or when the garbled character is less than or equal to the threshold value Reading the fixed part image data of the garbled part from the storage device, interpreting and drawing the non-garbled part included in the fixed part of the PDL data and the variable value included in the PDL data. To generate second drawing data, and to combine the fixed part image data of the garbled part with the second drawing data to generate second combined data. Drawing section,

  According to the present disclosure, when an image forming apparatus interprets PDL data and draws it to generate drawing data, it is possible to prevent garbled characters.

  Note that the effects described here are not necessarily limited, and may be any effects described in the present disclosure.

1 illustrates a hardware configuration of an image forming apparatus according to an exemplary embodiment of the present invention. 1 shows a functional configuration of an image forming apparatus. 3 shows an operation flow of the image forming apparatus.

  Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

  1. Hardware configuration of image forming apparatus

  FIG. 1 shows a hardware configuration of an image forming apparatus according to an embodiment of the present invention.

  The image forming apparatus 10 includes a control circuit 11. The control circuit 11 includes a CPU 11 a (Central Processing Unit) that is a processor, a RAM 11 b (Random Access Memory), a ROM 11 c (Read Only Memory) that is a memory, a dedicated hardware circuit, and the like, and the entire image forming apparatus 10 includes Manages motion control. The CPU 11a loads the information processing program stored in the ROM 11c into the RAM 11b and executes it. The ROM 11c fixedly stores programs and data executed by the CPU 11a. The ROM 11c is an example of a non-transitory computer-readable recording medium.

  The control circuit 11 includes an image reading unit 12 (image scanner), an image processing unit 14, an image memory 15, an image forming unit 16 (printer), an operation unit 17 (touch panel) including a display unit 17a, an HDD (Hard Disk Drive), and the like. It is connected to a large-capacity non-volatile storage device 18, such as an SSD (Solid State Drive), a facsimile communication unit 19, a network communication interface 13, and the like. The control circuit 11 controls the operation of each of the above-mentioned connected parts and transmits / receives signals or data to / from each part.

  2. Functional configuration of image forming apparatus

  FIG. 2 shows a functional configuration of the image forming apparatus.

  In the control circuit 11 of the image forming apparatus 10, the CPU 11a loads the image forming program 100 stored in the ROM 11c into the RAM 11b and executes the image forming program 100, thereby executing the character code determination unit 101, the data conversion unit 102, the garbled character determination unit 103, and the drawing. It operates as the unit 104 and the print control unit 105.

  The character code determination unit 101 acquires PDL data including a fixed portion that is not dependent on the print target data and a variable value that depends on the print target data, and determines whether the PDL data is described in a specific character code. To judge.

  When the PDL data is described with a specific character code, the data conversion unit 102 converts the PDL data into image data and generates converted data.

  The garbled character determination unit 103 performs optical character recognition on the converted data, determines whether the fixed portion included in the converted data includes the garbled character, and if the fixed portion includes the garbled character, determines whether the garbled character is greater than a threshold value. Determine whether or not.

  The storage device 18 stores the fixed part image data 112. The “fixed portion image data” is image data of the fixed portion that is independent of the data to be printed, and is stored in the storage device 18 in advance. For example, the storage device 18 stores the fixed part image data 112, which is the image data of the entire fixed part, by storing the image data of each of a plurality of parts obtained by dividing the fixed part included in the form (for example, the usage history report). May be stored.

  When the fixed part does not include garbled characters, the drawing unit 104 interprets and draws the PDL data to generate third drawing data. When the PDL data is not described in a specific character code or when the garbled characters are more than the threshold value, the drawing unit 104 reads the fixed part image data 112 from the storage device 18 and interprets the variable value included in the PDL data. Then, drawing is performed to generate first drawing data, and the fixed portion image data 112 and the first drawing data are combined to generate first combined data. When the garbled character is equal to or less than the threshold value, the drawing unit 104 reads the fixed part image data 112 of the garbled part from the storage device 18, and includes the non-garbled part and the PDL data included in the fixed part of the PDL data. The variable value is interpreted and drawn to generate the second drawing data, and the fixed part image data 112 of the garbled part and the second drawing data are combined to generate the second combined data.

  The print control unit 105 outputs the third drawing data, the first combined data, or the second combined data to the image forming unit 16.

  3. Operation flow of image forming apparatus

  FIG. 3 shows an operation flow of the image forming apparatus.

  As a premise, the HyPAS application 200 generates PDL data. The HyPAS application 200 is an application program executable in a specific platform (for example, HyPAS (Hybrid Platform for Advanced Solutions)) environment of the image forming apparatus 10. The PDL data is described by an arbitrary character code (for example, Shift_JIS). “Shift_JIS” is a character code used to represent a character string including Japanese and half-width alphanumeric characters. The PDL data includes a fixed part that does not depend on the print target data and a variable value that depends on the print target data. An example of PDL data generated by the HyPAS application 200 and including a fixed part and a variable value is a usage history report. The usage history report is typically a fixed part (service name, and further items such as date and time of use, number of prints, color mode, etc.), that is, a form value, and a variable value (number as date and time of use, number as number of prints). , Full color, gray scale, monochrome two gradations, etc.) are included as color modes.

  The character code determination unit 101 acquires PDL data from the HyPAS application 200 (step S101). The character code determination unit 101 determines whether the acquired PDL data is described in a specific character code (Shift_JIS in this example) (step S102).

  When the character code determination unit 101 determines that the PDL data is described in a specific character code (Shift_JIS) (step S102, YES), the data conversion unit 102 converts the PDL data into image data (for example, JPEG data). The converted data is generated and converted and stored (step S103).

  The garbled character determination unit 103 performs optical character recognition (OCR) on the converted data (step S104), and determines whether or not the fixed part included in the converted data contains garbled characters (step S105). For example, the garbled character determination unit 103 compares the expected value 111 of the image data of the fixed unit, which is stored in the storage device 18, with the value obtained by OCR. You can judge that it does not include a ghost.

  When the garbled character determination unit 103 determines that the fixed part included in the converted data does not include the character garbled (step S105, NO), the drawing unit 104 interprets and draws the PDL data generated by the HyPAS application 200 and draws the drawn data. (Third drawing data) is generated (step S106).

  On the other hand, when the garbled character determination unit 103 determines that the fixed part included in the converted data includes garbled characters (step S105, YES), the garbled characters are counted (step S107), and as a result of the counting, the character garbled threshold value ( (For example, 50%) is determined (step S108).

  When the garbled character determination unit 103 determines that the garbled character is greater than the threshold value (YES in step S108), the drawing unit 104 reads the fixed part image data 112 from the storage device 18. The drawing unit 104 interprets and draws a variable value included in the PDL data generated by the HyPAS application 200 to generate drawing data (first drawing data). The drawing unit 104 combines the fixed part image data 112 (image data of the entire fixed part) read from the storage device 18 and the first drawing data to generate combined data (first combined data) ( Step S109).

  On the other hand, when the garbled character determination unit 103 determines that the garbled character is less than or equal to the threshold value (NO in step S108), the drawing unit 104 reads the fixed part image data 112 of the garbled part (determined in step S105) from the storage device 18. . The drawing unit 104 interprets and draws a part included in the fixed part of the PDL data generated by the HyPAS application 200 that is not garbled (determined in step S105) and a variable value included in the PDL data to draw the drawing data. (Second drawing data) is generated. The drawing unit 104 combines the fixed part image data 112 of the garbled part read from the storage device 18 and the second drawing data to generate combined data (second combined data) (step S110). .

  By the way, when the character code determination unit 101 determines that the PDL data is not described by a specific character code (Shift_JIS) (step S102, NO), the drawing unit 104 reads the fixed portion image data 112 from the storage device 18. . The drawing unit 104 interprets and draws a variable value included in the PDL data generated by the HyPAS application 200 to generate drawing data (first drawing data). The drawing unit 104 combines the fixed part image data 112 (image data of the entire fixed part) read from the storage device 18 and the first drawing data to generate combined data (first combined data) ( Step S109).

  The print control unit 105 transfers the third drawing data (step S106), the first combined data (step S109), or the second combined data (step S110) generated by the drawing unit 104 to the image forming unit 16 (printer). Output (step S111).

  4. Conclusion

  When the HyPAS application 200 interprets and draws the PDL data described and generated in a font that the image forming apparatus 10 does not support, garbled characters occur. For example, the HyPAS application 200 can generate PDL data with various character codes (Shift_JIS and other character codes). However, the image forming program 100 that interprets and draws the PDL data cannot correctly interpret and draw unless the PDL data is described in a specific character code (Shift_JIS). In other words, the image forming program 100 interprets PDL data described in a character code other than a specific character code (Shift_JIS) (for example, a character code used to represent a character string including Chinese). When I draw it, the characters are always garbled.

  As a method of predicting whether or not garbled characters will occur, a method of determining whether or not the image forming apparatus 10 has a font list of fonts describing PDL data can be considered as an example. However, whether or not the image forming apparatus 10 has a font list typically requires a user or a service person to manually check the font list of the image forming apparatus 10, and the characters of all the image forming apparatuses 10 need to be checked. It is not an appropriate method to avoid ghosts. Further, even if the user or the service person checks the font list and determines that the garbled character does not occur, the garbled character may actually occur for some reason. In this case, the occurrence of garbled characters will be discovered only after the actual printing.

  On the other hand, according to the present embodiment, the character code determination unit 101 acquires PDL data including a fixed unit and a variable value that depends on the print target data, and the PDL data is described by a specific character code. It is determined whether or not it has been done. As a result, it is possible to surely determine the case where garbled characters occur (PDL data is not described with a specific character code). Further, the garbled character determination unit 103 performs optical character recognition on the converted data obtained by converting the PDL data into image data, and determines whether the fixed part included in the converted data contains garbled characters. As a result, even if the PDL data is described with a specific character code, it is possible to reliably determine the case where the garbled character occurs. Furthermore, when garbled characters are always generated (PDL data is not described with a specific character code) and when garbled characters are larger than the threshold value, the first image is stored using the fixed part image data 112 stored in advance in the storage device 18. Since the combined data of 1 is generated, garbled characters cannot occur. Further, when the garbled character is less than or equal to the threshold value, only the garbled part is used to generate the second combined data using the fixed part image data 112 stored in advance in the storage device 18, and thus the garbled character cannot occur. Since the use of the fixed part image data 112 is minimized, the amount of data is also saved.

  According to this embodiment, when the fixed part does not include garbled characters, the drawing unit 104 interprets and draws the PDL data to generate third drawing data. As a result, when it is determined in advance that the garbled characters will not occur, the fixed part image data 112 is not used, and the data amount is saved.

  Although each embodiment and each modified example of the present technology have been described above, the present technology is not limited to the above-described embodiments, and various modifications may be made without departing from the scope of the present technology. Of course.
