JP 2003-251863 A

  By the way, when the printer is replaced with a printer having a different resolution, the print quality of text as well as the barcode image may be affected. For example, when the resolution assumed by the host (application) differs from the resolution of the printer due to printer replacement, and image data including text information is sent from the host instead of a text print command Etc. In such a case, the image data is enlarged / reduced in the printer driver or the printer, so that the image is destroyed and the print quality of the text is deteriorated. In order to solve such problems, it is desirable to change the application together with the replacement of the printer and generate image data that matches the resolution of the printer, but since changing the application requires a large amount of money, it is a practical solution. Not right.

  In view of such problems, the present invention provides an image processing apparatus capable of maintaining the print quality of text without requiring application changes even when replacement with a printer having a different resolution is performed. An object is to provide an image processing system and a printing method.

  An image processing apparatus according to the present invention includes an image data acquisition unit that acquires first image data having a first resolution in a first direction including text information, and first image data acquired by the image data acquisition unit. Based on the analysis result analyzed by the text analysis unit, the second image data having the second resolution in the first direction including the text information is generated based on the analysis result analyzed by the text analysis unit. And an image data generation unit.

  The image processing system of the present invention includes an execution unit that executes an application that generates first image data having a first resolution in a first direction including text information, and the first image data generated by the application. The image data acquisition unit to acquire, the text analysis unit to analyze the text information included in the first image data acquired by the image data acquisition unit, the text information based on the analysis result analyzed by the text analysis unit An image processing device having an image data generation unit that generates second image data of the second resolution in a first direction including the transmission unit that transmits the second image data generated by the image data generation unit; A reception unit that receives the second image data transmitted by the transmission unit of the image processing apparatus, a print head that performs printing at the second resolution in the first direction, and a reception unit that receives the second image data. A printer having a control unit for printing the second image data to the print head, characterized by comprising a.

  The printing method of the present invention generates first image data having a first resolution in a first direction including text information, analyzes the text information included in the generated first image data, and performs analysis. Based on the result, generating second image data having the second resolution in the first direction including the analyzed text information, and printing the generated second image data at the second resolution. Features.

According to the configuration of the present invention, the first image data having the first resolution in the first direction (the width direction of the printing paper) including the text information is converted into the text using a technique such as OCR (Optical Character Recognition). In order to generate the second image data of the second resolution in the first direction including the text information based on the analysis result, the replacement with the resolution of the printer before the replacement (first resolution) Even when the resolution of the subsequent printer (second resolution) is different, it is possible to prevent deterioration of the print quality of the text without requiring an application change. In other words, if the enlargement / reduction process is simply performed according to the resolution of the printer after replacement, characters may be crushed or deformed, but once the text is analyzed, the second resolution is obtained. There is no such problem because it is converted into corresponding text information.
The “image processing apparatus” may be mounted on the host side or the printer side in a printing system including a host and a printer. In the former case, the image processing apparatus can be implemented as a printer driver.
The “text information corresponding to the second resolution” may be text image data corresponding to the second resolution. According to this configuration, the image processing apparatus can generate second image data including text image data corresponding to the second resolution.

  The image processing apparatus includes a print command generation unit that generates a print command to be printed by the printer based on the analysis result analyzed by the text analysis unit.

  According to the configuration of the present invention, the image processing apparatus can generate a print command that causes the printer to print text information corresponding to the second resolution. In the case of this configuration, the image processing apparatus is mounted on the host side as a printer driver.

  In the above image processing apparatus, a logo image data storage unit that stores logo image data having a resolution different from the first resolution in the first direction and the presence / absence of logo image data included in the first image data are analyzed. A logo analysis unit, and when the logo analysis unit analyzes that the logo image data included in the first image data is present, the image data generation unit converts the logo data image data included in the first image data The second image data is generated by replacing the logo image data stored in the logo image data storage unit.

  In the image processing apparatus, the image data generation unit converts the logo image data stored in the logo image data storage unit into logo image data corresponding to the second resolution, and includes the logo data included in the first image data. The image data is replaced with logo image data corresponding to the second resolution.

According to the configuration of the present invention, even when logo image data is included in the first image data, this is replaced with the logo image data corresponding to the second resolution, thereby preventing the print quality of the logo image from deteriorating. Can do.
Note that the “logo analysis unit” may perform analysis using a matching technique such as pattern matching. In this case, it is only necessary to collate with the logo image data stored in the logo image data storage unit.

  In the image processing apparatus, the first image data acquired by the image data acquisition unit is image data printed on a recording sheet having a first width in the first direction, and is generated by the image data generation unit. When the second image data is image data printed on a recording sheet having a second width different from the first width in the first direction, the image data generation unit converts the second image data to the second image data. It is generated according to the width.

  According to the configuration of the present invention, the same effect can be obtained not only when the resolution is different, but also when the number of dots and the length of the recording paper used in the printer before and after replacement are different. For example, when a printer having a recording paper width of 512 dots is replaced with a printer having a paper width of 752 dots, the image processing apparatus enlarges the image data by about 1.46 times, so that it looks good in accordance with the paper width. Although the print result can be realized, the print quality of the text is deteriorated by this enlargement process. For this reason, by applying the present invention, even when image data enlargement / reduction processing is performed in the image processing apparatus in order to absorb the difference in paper width used in the printer before and after replacement, deterioration of text print quality is prevented. be able to.

  The image processing apparatus image data generation unit generates third image data different from the second image data based on the analysis result analyzed by the text analysis unit.

According to the configuration of the present invention, since the third image data is generated by the image processing apparatus, an additional function such as adding coupon data to receipt data generated by an application can be realized.
The “third image data” is not limited to the coupon data described above, and data such as a receipt, a guarantee, a quality certificate, and an advertisement may be generated.

[First Embodiment]
Hereinafter, an image processing apparatus, an image processing system, and a printing method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The first embodiment exemplifies a case where image data including text and / or a logo image is printed, and the image processing apparatus of the present invention is mounted as the printer driver 12.

  FIG. 1 is a system configuration diagram of a printing system SY (image processing system). The printing system SY includes a PC 1 serving as a host device and a printer 2 that performs printing based on a print command from the PC 1. The personal computer (hereinafter referred to as “PC”) 1 and the printer 2 are connected via a network such as a cable or a LAN.

  The PC 1 has an application 11 that generates image data corresponding to a predetermined resolution and paper (number of dots and length in the paper width direction and conveyance direction), a printer driver 12 corresponding to the printer 2, and an image to be printed. A display 13 for displaying various information such as data, and a keyboard 14 and a mouse 15 for inputting various information are provided. Examples of the application 11 include a POS (Point Of Sales) application for issuing an accounting receipt and a form application used in a medical field. On the other hand, the printer 2 includes a printer control unit 21 that performs various controls such as data input / output control and printing control with the PC 1, and a printing mechanism 22 including a print head and a paper transport mechanism.

  The printer 2 of the present embodiment corresponds to a long sheet having a resolution of 360 dpi / paper width of 752 dots (paper width of 2.0 inches) in the paper width direction (first direction). It is assumed that the printer has been replaced with an old printer (not shown) having a resolution of 180 dpi / paper width of 512 dots (paper width of 2.8 inches) in the width direction (first direction). In this embodiment, it is assumed that “the resolution in the paper width direction” and “the resolution in the paper conveyance direction (paper longitudinal direction) (perpendicular to the paper width direction)” are the same. Hereinafter, unless otherwise specified, it means “resolution” = “resolution in the paper width direction”. The application 11 generates image data corresponding to the resolution and paper width of the old printer (first image data, hereinafter referred to as “image data for the old printer”). , Text and / or logo images.

  In such a system configuration, enlargement / reduction processing of image data by the printer driver 12 is necessary to absorb the difference in specifications between the printer 2 and the application 11 (corresponding difference in resolution and paper width). Therefore, in this embodiment, text analysis and pattern matching are performed by the printer driver 12, and image data corresponding to the resolution and paper width of the new printer 2 (second image data, hereinafter, "image data for the new printer 2"). The printing quality is ensured. The “logo image” refers to an image similar to logo image data stored in advance in the printer driver 12 (an image having a different resolution).

  FIG. 2 is a simplified flowchart showing a rough flow of the printing process according to the first embodiment. First, the application 11 generates image data (including text and / or logo images) for the old printer (S01). Next, the printer driver 12 performs text analysis using an OCR (Optical Character Recognition) function and / or logo image detection by pattern matching (S02). Here, it is determined whether or not text is included in the image data for the old printer, and if included (S03: Yes), the text is extracted and the text image corresponding to the resolution and paper width of the new printer 2 is extracted. Data is converted (S04). If no text is included (S03: No), S04 is omitted. Subsequently, the printer driver 12 determines whether or not a logo image is included in the image data for the old printer. If included (S05: Yes), the logo image data for the old printer is used for the new printer 2. (S06). If the logo image is not included (S05: No), S06 is omitted. Thereafter, text image data and / or logo image data for the new printer 2 is transmitted to the printer 2 (S07). The printer 2 prints the received text image data and / or logo image data for the new printer 2 on a predetermined printing paper (S08).

  Note that the image data for the old printer generated by the application 11 may include information other than text and logo images. In this case, image data portions other than text and logo images are enlarged / reduced according to the difference in resolution and paper width of the printer 2 before and after replacement. In this case, the resolution and paper width of the old printer may be set in the printer driver 12, and the enlargement / reduction process may be performed according to the difference in specifications with the new printer 2 that it corresponds to. For example, when the number of dots of the paper width is changed from 512 dots to 752 dots by changing the resolution and paper width length of the printer 2 before and after replacement as in the present embodiment, the image data is about 1. What is necessary is just to enlarge 46 times. If only the resolution is changed from 180 dpi to 360 dpi, the image data may be enlarged twice in the paper width direction. Also, the user may be able to set the enlargement rate or reduction rate. If the image data for the old printer includes a barcode image or a two-dimensional code image, an accurate reading result can be obtained when the printing result is read by a barcode reader or the like by simply performing enlargement / reduction processing. Since there is a possibility of disappearing, it is preferable to perform enlargement / reduction processing excluding these code image areas.

  Next, the functional configuration of the printing system SY will be described with reference to FIG. The application 11 includes an execution unit 110 as a main functional configuration. The execution unit 110 is an execution environment for the application 11.

  The printer driver 12 includes an image data acquisition unit 120, an analysis unit 130, an image data generation unit 160, a transmission unit 170, a logo image data storage unit 180, and an additional image form storage unit 190 as main functional configurations.

  The image data acquisition unit 120 acquires image data for the old printer from the application 11 (execution unit 110). The image data is image data printed on a receipt paper (recording paper) having a paper width of 512 dots by an old printer having a resolution of 180 dpi. The analysis unit 130 includes a text analysis unit 131 and a logo analysis unit 132. The text analysis unit 131 analyzes text information included in the image data for the old printer. Here, “analysis” refers to reading the image data for the old printer as an image and recognizing the text portion. For example, FIG. 4A shows a print result of an old printer (resolution 180 dpi / paper width 512 dots), and an example of receipt image data R1 issued when a POS application is used as the application 11. Show. In the same figure, the code | symbol L1 shows the logo image data for old printers, and the code | symbol T1 shows the text image data for old printers. The text analysis unit 131 reads the receipt image data R1 as an image, and performs character recognition for extracting text from the text image data T1.

  On the other hand, the logo analysis unit 132 analyzes the presence / absence of logo image data included in the image data for the old printer. That is, it is analyzed whether the logo image data L1 corresponding to the resolution of the old printer (resolution 180 dpi) is included. Here, “analysis” refers to reading image data for the old printer (receipt image data R1) and performing pattern matching with the logo image data for the new printer 2 stored in the logo image data storage unit 180. Point to. For example, FIG. 4B shows an example of receipt and coupon image data R2 and C issued by the new printer 2 (resolution 360 dpi / number of dots of paper width 752 dots). The logo analysis unit 132 analyzes whether the logo image data L1 is included in the receipt image data R1 acquired from the application 11, using the logo image data L2 shown in FIG. The coupon will be described later.

  As described above, the logo image data storage unit 180 stores the logo image data for the new printer 2. The additional image form storage unit 190 stores a coupon print form. In the present embodiment, image data corresponding to the specifications of the new printer 2 including the information of the photograph and text (excluding the text 41 indicating the expiration date) shown on the coupon of FIG. Is remembered.

  The image data generation unit 160 generates receipt image data R2 (second image data) and coupon image data C (additional image data) shown in FIG. The image data generation unit 160 prints the image data R2 of the receipt on the number of dots of the paper width (second width) different from the number of dots of the paper width (first width) used in the old printer. , The receipt image data R2 and the coupon image data C are generated in correspondence with the number of dots of the paper width (752 dots) used in the new printer 2. In addition, when generating the image data C of the coupon, it may be generated as separate image data so that the printer 2 performs a cutting process after printing the receipt, and further prints the coupon. You may produce | generate as one image data so that it may be issued in the state in which the coupon was connected. Further, when the printer 2 has a half-cut function, the image data may be generated so that the space between the receipt and the coupon is half-cut.

  First, the image data generation unit 160 converts the analysis result of the text analysis unit 131 into text information corresponding to the new printer 2. In this embodiment, text image data T2 corresponding to the specifications of the new printer 2 (resolution 360 dpi / number of dots of paper width 752 dots) is generated as “text information”. Further, when the logo analysis unit 132 detects the logo image data L1 corresponding to the resolution of the old printer from the image data for the old printer, the logo image data L1 is converted to the logo image corresponding to the specifications of the new printer 2. Replace with data L2.

  In addition, when the text analysis unit 131 detects a predetermined text (keyword) from the text image data T1, the image data generation unit 160 has associated coupon image data C (an image corresponding to the specifications of the new printer 2). Data) is generated and added to the receipt image data R2. FIG. 4B shows a case where a discount coupon for apples is issued with the detection of the keyword “apples”. Further, when generating the image data C of the coupon, the image data generation unit 160 determines an expiration date according to the current date and time, and the expiration date text 41 is printed on the print form read from the additional image form storage unit 190. insert.

  The additional image form storage unit 190 may store a large number of print forms in association with a plurality of types of keywords and products. If the customer ID can be extracted from the analysis result of the text image data T2, the customer database (not shown) is referred to with the customer ID as an argument, and the date of birth corresponds to the birthday of the customer. A coupon may be issued. Further, referring to the customer database, a coupon suitable for the customer may be issued according to the sex, age, and purchase frequency of the customer.

  The transmission unit 170 transmits the image data for the new printer 2 generated by the image data generation unit 160 to the printer 2. On the other hand, the printer 2 (new printer 2) includes a receiving unit 210 and a printing unit 220 as main functional configurations. The reception unit 210 receives image data for the new printer 2 transmitted from the printer driver 12 (transmission unit 170). The printing unit 220 includes the printer control unit 21 and the printing mechanism 22, and prints image data for the new printer 2 received by the receiving unit 210.

  As described above, according to the first embodiment, the text image data T1 for the old printer is subjected to text analysis by the OCR technique, and the analysis result is converted to the text image data T2 for the new printer 2, so that replacement is performed. Even when the resolutions of the front and rear printers 2 are different and enlargement / reduction processing is necessary, the print quality of the text can be maintained without requiring the application 11 to be changed. That is, instead of simply performing enlargement / reduction processing, the text analysis result is converted into image data in accordance with the resolution of the new printer 2, thereby eliminating the problem that characters are crushed or deformed. Further, not only when the resolution is different, but also when the number of dots and the length of the paper width used in the printer 2 before and after the replacement are different, it is possible to prevent the text print quality from being deteriorated.

  Further, even when the logo image data L1 is included in the receipt image data R1, this is replaced with the logo image data L2 corresponding to the new printer 2, so that not only the text but also the print quality of the logo image can be ensured.

  Further, since the coupon image data C (third image data) is generated based on the analysis result of the text analysis unit 131, a coupon printing function can be added without changing the application 11.

  In the above embodiment, the case where the image data of the coupon is generated as the “third image data” is exemplified. Data such as quality certificates and advertisements may be added.

  In addition, the logo image data storage unit 180 and the additional image form storage unit 190 store the logo image data and the additional image form corresponding to the new printer 2. An image form may be stored and the image data reduced according to the specifications (resolution and paper width) of the new printer 2 may be used. According to this configuration, the common logo image data and the additional image form can be used by the printer driver 12 corresponding to various specifications. In consideration of replacement with a printer 2 capable of color printing, a configuration in which logo image data corresponding to color printing and an additional image form are stored may be used. In this case, the monochrome printer driver 12 converts the color data into monochrome data and uses it.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. In the first embodiment, the printer driver 12 converts the text for the old printer into the text image data for the new printer 2, but in this embodiment, the text is converted into a text print command instead of the text image data. It is different in point. That is, in the present embodiment, it is assumed that the printer 2 can interpret the text print command. Hereinafter, a description will be given focusing on differences from the first embodiment. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, the modification applied about the component similar to 1st Embodiment is applied similarly about this embodiment.

  FIG. 5 is a simplified flowchart showing a rough flow of the printing process according to the second embodiment. First, the application 11 generates image data for the old printer (S11). Next, the printer driver 12 performs OCR analysis and pattern matching of the logo image (S12). Up to this point, the process is the same as in the first embodiment. Thereafter, the printer driver 12 determines whether or not text is included in the image data for the old printer. If the text is included (S13: Yes), the printer driver 12 extracts the text and converts it into a text print command (S14, Print command generator). The text print command is a print command that can be interpreted by the printer 2. Further, a font size corresponding to the resolution and paper width of the new printer 2 may be designated. Furthermore, not only the resolution and paper width of the new printer 2 but also the number of characters in the paper width direction (line direction) may be considered to specify an appropriate font size. If the text is not included (S13: No), S14 is omitted. Subsequently, the printer driver 12 determines whether or not a logo image is included in the image data for the old printer. If included (S15: Yes), the logo image data for the old printer is used for the new printer 2. (S16). If no logo image is included (S15: No), S16 is omitted. Thereafter, a text print command and / or logo image data for the new printer 2 is transmitted to the printer 2 (S17). The printer 2 interprets the received text print command (S18), and prints the interpretation result and / or logo image data for the new printer 2 on a predetermined printing paper (S19).

  As described above, according to the second embodiment, the printer driver 12 converts the text information included in the image data for the old printer into the text print command instead of the text image data. In comparison, the amount of data transmitted to the printer 2 can be reduced.

  Note that the present embodiment may be combined with the first embodiment, and the user may arbitrarily set whether to convert the extracted text into text image data or text print commands.

[Third Embodiment]
Next, a third embodiment of the present invention will be described with reference to FIG. In the first and second embodiments described above, OCR analysis and pattern matching are performed by the printer driver 12, but in the present embodiment, the printer 2 is different. That is, in this embodiment, the “image processing apparatus” of the present invention is realized by the printer 2. The following description will focus on differences from the above embodiments. In the present embodiment, the modification applied to the same components as those in each of the above embodiments is similarly applied.

  FIG. 6 is a simplified flowchart showing a rough flow of the printing process according to the third embodiment. First, the application 11 generates image data for the old printer (S21). Next, the printer driver 12 instructs the printer 2 to print image data for the old printer (S22). The printer 2 acquires image data for the old printer from the printer driver 12, and performs OCR analysis and logo image pattern matching (S23). Here, it is determined whether or not text is included in the image data for the old printer. If the text is included (S24: Yes), the text is extracted and converted to text image data for the new printer 2 (S25). ). If the text is not included (S24: No), S25 is omitted. Subsequently, the printer 2 determines whether or not a logo image is included in the image data for the old printer. If included (S26: Yes), the logo image data for the old printer is used as the logo image data for the new printer 2. Replace with logo image data (S27). If no logo image is included (S26: No), S27 is omitted. Thereafter, text image data and / or logo image data for the new printer 2 is printed on a predetermined printing paper (S28).

  As described above, according to the third embodiment, since the OCR analysis and pattern matching are performed on the printer 2 side, the processing load on the printer driver 12 can be reduced. Even when the PC 1 is driverless (for example, when the PC 1 is operated by cloud computing), the effects of the present invention can be achieved.

  Although the first to third embodiments have been described above, it is possible to provide each component of the printer driver 12 or the printer 2 described in each embodiment as a program. Further, the program can be provided by being stored in various recording media (CD-ROM, flash memory, etc.). That is, a program for causing a computer to function as each component of the printer driver 12 or the printer 2 and a recording medium on which the program is recorded are also included in the scope of rights of the present invention.

  In each of the above embodiments, the case where the resolution and the paper width of the printer 2 before and after replacement are different is illustrated, but “resolution only” or “paper width only (only the number of dots in the paper width, or the length of the paper width).
