Description

  The present invention relates to an image processing apparatus, an image processing system, and a printing method that perform image processing for printing a symbol image.

  Conventionally, Patent Document 1 has been proposed as a technique related to printing of symbol images (for example, barcode images). Patent Document 1 relates to a printer having a function of interpreting a barcode code drawing command transmitted from a host and developing an image. By enabling an operator to input a barcode enlargement / reduction ratio, This prevents bar codes from shrinking or extending due to differences in engine characteristics, resolution, conveyance direction, and the like.

[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. In the first embodiment, an example in which the image processing apparatus of the present invention is mounted as a printer driver will be described.

  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 includes an application 11 for generating a barcode image (symbol image), a printer driver 12 corresponding to the printer 2, a display 13 for displaying various information such as image data to be printed, and a keyboard 14 for inputting various information. And a mouse 15. As the application 11, a form application used in a medical field is assumed. 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 this embodiment corresponds to a resolution of 360 dpi, and is assumed to be replaced with an old printer with 300 dpi. The application 11 generates image data corresponding to a 300 dpi old printer, and the image data includes image data (information) of a barcode image. In such a system configuration, the print quality of the barcode image deteriorates due to the difference in resolution. For this reason, in this embodiment, the printer driver 12 absorbs the difference in resolution and maintains the print quality of the barcode image.

  FIG. 2 is a simplified flowchart showing a rough flow of the printing process according to the first embodiment. First, the application 11 generates a barcode image in which a numerical value “12345678” is created for 300 dpi, for example (S01). Next, the printer driver 12 analyzes the barcode image using the barcode reader function and converts the barcode image into a numerical value “12345678” (S02). Thereafter, the numerical value “12345678” is converted into a barcode image that can be guaranteed at 360 dpi of the new printer 2, and a print command is issued to the printer 2 (S 03). Based on the print command, the printer 2 prints a barcode image for 360 dpi on a predetermined print sheet (S04).

  Actually, the application 11 does not generate only the barcode image, but generates image data (D1) including the barcode image (B1) as a part (see FIG. 4A and the like). Then, the printer driver 12 determines whether or not the acquired image data includes a barcode image. If the barcode image is included, the printer driver 12 performs each process illustrated in FIG. Hereinafter, functions of the printer driver 12 will be described in detail.

  FIG. 3 is a functional block diagram of the printer driver 12 according to the first embodiment. The printer driver 12 includes an image data acquisition unit 120, an analysis unit 130, an information conversion unit 140, a print position designation unit 150, an image data generation unit 160, and an image data output unit 170 as main functional configurations.

  The image data acquisition unit 120 acquires first image data including image data (information) of a barcode image corresponding to the resolution of the old printer (first resolution, 300 dpi in the present embodiment) from the application 11. The analysis unit 130 analyzes the barcode image information corresponding to the resolution of the old printer included in the first image data. Here, “analysis” refers to reading the first image data as an image and decoding the barcode image.

  The information conversion unit 140 converts the analysis result of the analysis unit 130 into print information (barcode image information) for printing a barcode image corresponding to the resolution of the new printer 2 (second resolution, 360 dpi in the present embodiment). Convert. In this embodiment, “print information” is converted into image data of a barcode image corresponding to the resolution of the new printer 2. That is, the numeric string that is the analysis result of the analysis unit 130 is converted into image data of a barcode image for 360 dpi.

  The print position designation unit 150 designates the print position of the image data (print information) of the barcode image in the image data (second image data). A method for specifying the print position will be described later. The image data generation unit 160 generates second image data in which the print information (barcode image image data) converted by the information conversion unit 140 is arranged at a position based on the designation of the print position designation unit 150. The image data output unit 170 outputs the second image data generated by the image data generation unit 160 to the printer 2.

  Although not particularly illustrated, the PC 1 has an execution unit that executes an application 11 that generates first image data having symbol image information corresponding to the first resolution as a functional configuration other than the printer driver 12, and an image. A transmission unit that transmits the second image data generated by the data generation unit 160 (second image data output from the image data output unit 170) to the printer 2. The printer 2 also includes a receiving unit that receives the second image data transmitted from the transmitting unit, a print head that performs printing at the second resolution, and a print head that receives the second image data received by the receiving unit. And a control unit (printer control unit 21) that performs printing by the (printing mechanism 22).

  FIG. 4 is an explanatory diagram regarding setting of the print position of the barcode image. Each drawing in FIG. 4 shows an image of image data, and does not show a printing result. FIG. 4A shows first image data D1 including a barcode image for 300 dpi (hereinafter referred to as “first barcode image B1”). FIG. 4B shows second image data D2 obtained by enlarging the first image data D1 excluding the first barcode image B1. This is because if the first image data D1 corresponding to 300 dpi is printed as it is by the printer 2 for 360 dpi, it is printed slightly smaller (because the printing range on the prescribed paper becomes narrow), so that the prescribed paper width is achieved. Enlarged to fit. Note that the enlargement rate is specified (input) by the user.

  FIG. 4C shows a state where the print range E1 is designated on the second image data D2. The print range E1 is specified by, for example, displaying the second image data D2 of FIG. 4B on the display 13 and operating the keyboard 14 or the mouse 15 by the user. FIG. 4D shows a state in which a barcode image for 360 dpi (hereinafter referred to as “second barcode image B2”) is arranged in the designated print range E1 of the second image data D2. Show. Here, the second barcode image B2 is arranged in accordance with the reference position of the print range E1 (the center of the print range E1, one of the four vertices of the print range E1, etc.). Further, the second barcode image B2 may be enlarged or reduced according to the size of the print range E1 (horizontal width and / or vertical width). However, when performing enlargement or reduction processing, it is preferable not to simply enlarge or reduce the barcode image, but to adjust the number of dots printed on each bar of the barcode in accordance with the resolution after conversion.

  Thus, since the user can designate the print range E1 of the second barcode image B2 on the second image data D2, the printing of the second barcode image B2 is performed according to the designation of the enlargement / reduction ratio by the user. Even when the area is enlarged or reduced, the appearance of the printed matter is not impaired, for example, the barcode position is shifted.

  In the example of FIG. 4, the print range E1 is specified, but a reference position (print position) of the print range E1 may be specified. In the example of FIG. 4, the first image data D1 is enlarged to generate the second image data D2. However, the enlargement processing is not necessarily required. When the enlargement process is not performed, the print range E1 (or print position) may be specified on the second image data D2 obtained by removing the first barcode image B1 from the first image data D1.

  As described above, according to the first embodiment, the barcode image corresponding to the old printer is analyzed, and the analysis result is converted to the image data for printing the barcode image corresponding to the new printer 2. Even when the front and rear printers 2 have different resolutions, the print quality of the barcode image can be maintained without requiring the application 11 to be changed.

  Further, since the print range E1 of the second barcode image B2 on the second image data D2 can be designated, the print area of the barcode image is enlarged or reduced by the enlargement / reduction processing of the image data due to the difference in resolution. In this case, even if the actual print size on the paper is different by not performing the enlargement / reduction process on the entire image data, the appearance of the printed matter is not impaired.

  In the first embodiment, the user directly designates the print range E1 in order to specify the print position of the second barcode image B2 on the second image data D2. The printer resolution may be designated (resolution designation section). Hereinafter, this configuration will be described as a first modification. FIG. 5 is an explanatory diagram regarding the setting of the print position of the barcode image according to the first modification. FIG. 5A shows the first image data D1 including the first barcode image B1. FIG. 5B shows a second image obtained by enlarging the first image data D1 in accordance with the resolution of the designated old printer and the resolution of the new printer 2 (resolution supported by the printer driver 12). Image data D2 is shown. Here, since the first image data D1 including the first barcode image B1 is enlarged as it is, the quality of the barcode portion cannot be guaranteed. In FIG. 5B, as in the example of FIG. 4, enlargement is performed to fit the specified paper width, but enlargement processing may be omitted to reduce the actual print size.

  FIG. 5C shows a state in which the barcode image area E2 is automatically trimmed on the second image data D2. FIG. 5D shows a state where a separately generated barcode image for 360 dpi (second barcode image B2) is arranged in the trimmed region (= barcode image region E2). Here, the second barcode image B2 is arranged in accordance with the reference position of the barcode image area E2 (the center of the printing range E1, one of the four vertices of the printing range E1, etc.). Further, the second barcode image B2 may be enlarged or reduced according to the size (horizontal width and / or vertical width) of the barcode image area E2. 5B to 5C show processing steps by the printer driver 12 (image data generation unit 160).

  As described above, according to the first modification, it is possible to accurately perform the process according to the difference between the first resolution and the second resolution only by designating the first resolution. Further, the second barcode image B2 in the second image data D2 can be set at an appropriate position according to the arrangement of the barcode image after the enlargement / reduction processing (= barcode image region E2). it can.

  As a second modification, the enlargement / reduction ratio of the first image data D1 may be determined from information on the print paper size. Although not particularly illustrated, in this case, it is assumed that information about the print paper size is added (or included) to the first image data D1 output from the application 11. The printer driver 12 (image data generation unit 160) determines the enlargement / reduction ratio of the first image data D1 based on the print paper size and the first image data D1. Then, enlargement or reduction processing of the first image data D1 is performed at the determined enlargement / reduction ratio (see FIG. 5B), and the barcode image area E2 after the enlargement or reduction processing (bars for which quality cannot be guaranteed). The position of the second barcode image B2 in the second image data D2 is set according to the trimming area of the code image (see FIG. 5C). As described above, according to the second modification, the second image data D2 is appropriately printed so as to be printed in a size corresponding to the print paper size set in advance in the first image data D1. Enlargement / reduction processing can be performed. Note that the first and second modifications may be combined, and the enlargement / reduction ratio of the first image data D1 may be determined based on the designated first resolution and information on the print paper size. .

[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 performs conversion to the second barcode image B2. However, in the present embodiment, conversion to the second barcode image B2 is performed on the printer 2 side. It is different. That is, in the present embodiment, it is assumed that the printer 2 can interpret a barcode image print command (barcode code drawing 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.

Next, the printer driver 12 analyzes the first barcode image B1 using the barcode reader function, and converts it into a numerical value “12345678” (S12). Up to this point, the process is the same as in the first embodiment. Thereafter, the printer driver 12 converts the barcode image having the numerical value “12345678” into a print command for printing (S13), and the print command and the second image data D2 (enlargement processing of the first image data D1). Or the first image data D1 itself) is output to the printer 2. Based on the print command, the printer 2 converts the numerical value “12345678” into the second barcode image B2 that can be guaranteed at 360 dpi of the new printer 2 (S14), and the second barcode image B2 including the second barcode image B2 is converted. The image data D2 is printed (S15).

  As described above, according to the second embodiment, since the conversion to the second barcode image B2 is performed on the printer 2 side, the processing load on the printer driver 12 can be reduced. Also in this embodiment, the designation by the print position designation unit 150 is possible, and the designation result is output to the printer 2 together with a print command for printing a barcode image. Information indicating the position of the barcode image area E2 on the second image data D2 shown as the first and second modifications is also output to the printer 2 together with the print command for printing the barcode image.

Next, the printer driver 12 outputs the first image data D1 including the first barcode image B1 to the printer 2 (S22). The printer 2 analyzes the first barcode image B1 using the barcode reader function, and converts it into a numerical value “12345678” (S23). Also, the numerical value “12345678” is converted into the second barcode image B2 that can be guaranteed at 360 dpi of the new printer 2 (S24), and the second image data D2 including the second barcode image B2 is printed (S24). S25).

  As described above, according to the third embodiment, since the first barcode image B1 is analyzed and converted into the second barcode image B2 on the printer 2 side, compared to the second embodiment, The processing load on the printer driver 12 can be further reduced. In this embodiment as well, the designation by the print position designation unit 150 may be possible. In this case, display means and input means are required on the printer 2 side.
