Description

  The present invention is obtained by converting RGB of first document data (hereinafter referred to as photographic document RGB data) in which the color of an image is represented by R (red), G (green), and B (blue) as first color information. The present invention relates to an editing apparatus that lays out second document data (hereinafter referred to as photographic document CMYK data) indicated by C (cyan) M (magenta) Y (yellow) K (black) as second color information.

  Conventionally, in the printing plate making industry, photographic original CMYK data in which the color of an image is represented by CMYK has been used for editing. The photographic original CMYK data was previously generated from a positive film or the like using a drum scanner or the like. In other words, the generated photographic original CMYK data is input to a computer and transferred to the layout department for editing, and the layout department uses the photographic original CMYK data for editing.

  On the other hand, due to the recent spread of digital cameras, higher performance and higher image quality, there is a tendency to increase the number of submissions using digital data obtained by digital cameras. However, since the digital data of the digital camera is photographic original RGB data indicating the color of the image in RGB, it is necessary to convert it into photographic original CMYK data for use in editing.

  For example, the conventional procedure from submission of RGB data to generation of raster data used for printing is as follows: (1) convert photographic original RGB data into photographic original CMYK data; (2) use photographic original CMYK data. The layout image data is created by editing (layout), and (3) the layout image data is converted into raster data (RIP processing) to generate print image data used for printing. The procedure for first performing color conversion in this way is called upstream color conversion.

  However, since the color reproduction gamut by CMYK is smaller than the color reproduction gamut by RGB, the color reproduction gamut is compressed and converted from the photographic original RGB data to the photographic original CMYK data. Therefore, conversion from the photographic original RGB data to the photographic original CMYK data tends to occur when the converted color does not become the intended color due to the difference in the color reproduction areas of RGB and CMYK. Further, it is easier to obtain the intended color by converting the photographic original RGB data again than performing color adjustment using the photographic original CMYK data in which the color reproduction range is compressed. Therefore, when printing is performed based on the printing image data and a color defect is found in the printed matter, first, the original photographic original RGB data must be searched, and the operation must be repeated from (1). And had to spend time. If the original photographic original RGB data is not at hand (for example, if it has been erased), color adjustment may be performed using the photographic original CMYK data, and the color may not be as expected.

  In addition, a processing apparatus has been proposed that lays out a photographic original RGB data and attaches a file indicating color conversion to create layout image data, and performs color conversion based on the attached file to generate raster data ( For example, see Patent Document 1.) According to the processing apparatus described in Patent Document 1, it is possible to perform reconversion by changing the attached file. However, it cannot be applied to upstream color conversion in which photographic original CMYK data is laid out on layout image data conventionally performed in the printing plate making industry.

  Hereinafter, various embodiments of an editing apparatus according to the present invention will be described in detail with reference to the drawings.

<First Embodiment>
<Control configuration>
An editing apparatus according to a first embodiment of the present invention will be described. The editing apparatus according to the present embodiment is a so-called PC (Personal Computer) and includes a computer main body, a keyboard, a monitor, and the like. Further, a predetermined program is incorporated in the computer main body, and this program is executed to perform image processing described later.

  The functions of the editing apparatus according to this embodiment will be described with reference to FIG. FIG. 1 is a functional block diagram for explaining a control configuration of the editing apparatus according to the first embodiment.

  The accepting means 21 accepts the photographic original RGB data (first original data) and sends it to the managing means 22. The photographic original RGB data indicates a pixel by the intensity of each light of RGB (first color information), and indicates the intensity as a gradation value. Here, the gradation value is a value that indicates the intensity of light step by step using a numerical value from 0 to 100 or from 0 to 255. For example, black is indicated as (R0, G0, B0), and white is indicated as (R255, G255, B255) when using gradation values 0 to 255. The accepting means 21 is connected to means for receiving photographic original RGB data transmitted from the terminal device via a network, a digital camera, a scanner, etc. via a cable or the like, and photographic original RGB data obtained by photographing. Or a medium on which a photographic original RGB data is recorded, for example, a recording medium such as a CD-ROM (compact disk-read only memory) is detachable, and a photograph written on the mounted recording medium It comprises means for reading the original RGB data. Further, it may be a means for acquiring photographic original RGB data created using application software that operates on an editing apparatus.

  The input unit 20 includes an input device such as a keyboard and a pointing device such as a mouse / trackball for performing various inputs and operations. Then, signals corresponding to various inputs and operations are output to the management means 22.

  The management unit 22 receives the received photographic original RGB data and stores it in the image data storage unit 23. In addition, in response to an instruction to convert the color of the target photographic original RGB data using the input unit 20, the photographic original RGB data to be converted is read from the image data storage unit 23, and color conversion indicating the content of the color conversion is performed. The information is sent to the color conversion means 24 together with the information. This color conversion information is input using the input means 20 together with a color conversion instruction.

  The LUT storage unit 26 is an RGB → CMYK lookup table indicating a conversion relationship between RGB and CMYK (second color information), or an RGB indicating a relationship between RGB and L * a * b * color system values → A color profile such as an L * a * b * look-up table or a CMYK → L * a * b * look-up table indicating the relationship between CMYK and L * a * b * color system values is stored.

  For example, a plurality of RGB → CMYK lookup tables having different conversion relationships are stored. A plurality of color profiles are also stored. For example, a monitor profile indicating the color characteristics of the monitor, an RGB profile such as sRGB indicating the color reproduction range for RGB, and a CMYK profile indicating the color reproduction range for CMYK. and so on. In addition to this, a printer profile indicating the color characteristics of a printer, a color characteristic output by a printing machine, various profiles such as a print profile for each of a plurality of paper types, a LUT (Look up table) indicating color conversion characteristics, and the like There are color profiles.

  The color conversion unit 24 converts the target photographic original RGB data using, for example, a look-up table stored in the LUT storage unit 26 indicated by the color conversion information input using the input unit 20, and converts the color of the image to CMYK. Photo manuscript CMYK data (second manuscript data) indicated by gradation values of each color is generated.

  The color conversion information may be identification information such as a name or a number indicating a lookup table stored in the LUT storage unit 26, for example. In addition, if the LUT storage unit 26 stores, for example, an image type such as a landscape or a person in association with a lookup table, the image type can be used as color conversion information.

  Further, the color conversion unit 24 includes a function as an image processing unit that performs image processing related to colors such as so-called γ correction, sharpness, and contrast, and the color conversion information includes information on whether or not to perform these image processings. In this way, the color conversion means 24 may perform the above-described image processing together with conversion to photographic original CMYK data based on the color conversion information. Since this image processing is related to color, it is called “conversion” including image processing.

  Further, the management unit 22 attaches identification information (file name or the like) to the photographic original CMYK data generated by the conversion and stores it in the image data storage unit 23. Then, the correspondence between the photographic original CMYK data and the original photographic RGB data to be converted is written in the database 25.

  The database 25 is a database having a function as correspondence relationship storage means for storing the correspondence relationship between the photographic original CMYK data and the photographic original RGB data from which color conversion is performed. FIG. 2 shows an example of the configuration of the database 25. As shown in FIG. 2, for example, the file name of the photographic original CMYK data and the file name of the photographic original RGB data are associated with each other to indicate the correspondence. The file name of the photographic original CMYK data may correspond to the address of the photographic original RGB data in the image data storage means 23. Further, management such as writing and updating is performed by the management means 22.

  The layout unit 27 reads out the photographic document CMYK data to be laid out from the image data storage unit 23, and based on the photographic document CMYK data to be laid out input using the input unit 20 and an instruction of a desired position, the photographic document. Layout image data in which an image based on CMYK data is arranged at a desired position is created. For example, the upper left corner of the photographic original CMYK data is used as a reference point, and the coordinate position of the reference point is determined based on the instruction. For example, this coordinate position becomes layout information. However, the layout information is not limited to the coordinate position of the reference point, and may be information indicating a region, for example. As shown in FIG. 3, the layout image data includes layout image data identification information (file name, etc.), layout information of photo original CMYK data, and photo original CMYK data with identification information attached thereto. . FIG. 4 shows an example of an image indicated by the layout image data. As shown in FIG. 4, the layout image data indicates an image in which images based on, for example, photographic original CMYK data are arranged according to the layout information. The layout image data is temporarily stored in the memory 28.

  The display control unit 30 causes the display unit 29 to display, for example, the image shown in FIG. 4 based on the layout image data. Further, an input menu screen is generated based on an input from the input means 20 or a program and displayed on the display means 29. This input menu screen is used for various inputs to the displayed image, for example. For example, the input menu screen is a menu that is displayed by so-called right-clicking the mouse. For example, a print instruction, a re-conversion instruction, color conversion information, and the like are selectably displayed.

  When the RIP processing unit 31 receives a printing instruction from the input unit 20, the RIP processing unit 31 converts the layout image data into raster data (bitmap data) and sends the raster data to a printing apparatus (not shown). The data converted into the raster data may be called print image data.

  Further, for example, when there is a problem in color conversion when looking at the printed matter, the editing apparatus according to the present embodiment uses the input unit 20 to instruct the conversion of a specific photo original CMYK data image again. be able to. For example, the display control means 30 is displayed on the display means 29 by right-clicking at a position where an image to be reconverted on the displayed image using a pointing device such as a mouse or a trackball of the input means 20 is displayed. Display the input menu screen, select color conversion information for reconversion, and instruct reconversion.

  The management means 22 is specified with reference to the database 25 and a function as a specification means for specifying the photo original CMYK data specified based on the information indicating the position where the right-click is performed and the layout information of the layout image data. It has a function as a discriminating means for discriminating photographic original RGB data corresponding to the photographic original CMYK data. The photographic original RGB data is read from the image data storage means 23 and is supplied to the color conversion means 24 together with the color conversion information for reconversion. send.

  At this time, the identification information of the newly generated photographic original CMYK data may be the identification information of the previous photographic original CMYK data, or may be newly created and attached. However, when creating a new one, it is necessary to newly write or update the correspondence relationship in the database 25.

  The color conversion unit 24 converts the photographic original RGB data sent from the management unit 22 using a lookup table stored in the LUT storage unit 26 indicated by the reconversion color conversion information, and generates photographic original CMYK data. To do.

  The layout unit 27 replaces the photographic original CMYK data instructed to reconvert layout image data with the photographic original CMYK data obtained by the reconversion.

  The display control unit 30 causes the display unit 29 to display an image based on the layout image data in which the photographic original CMYK data is replaced.

  When the RIP processing unit 31 receives a print instruction from the input unit 20, the RIP processing unit 31 converts the layout image data in which the photographic original CMYK data is replaced into raster data and sends the raster data to a printing apparatus (not shown).

<Color conversion procedure>
Next, a color conversion procedure in the editing apparatus according to the present embodiment will be described with reference to FIGS. FIG. 5 and FIG. 6 are flowcharts showing the conversion procedure, including the re-conversion procedure.

  First, as shown in FIG. 5, when the accepting means 21 receives the photographic original RGB data, the management means 22 stores the photographic original RGB data at a predetermined position in the image data storage means 23 (step S101; hereinafter, step). S101 is abbreviated as S101, and other steps are also abbreviated as well.) In this way, the photographic original RGB data is stored in the image data storage means 23.

  Then, when an instruction to convert the color of the target photographic original RGB data by the operator is input using the input unit 20 together with the color conversion information related to the conversion (S102, Y), the management unit 22 The photographic original RGB data is read from the image data storage means 23, and the target photographic original RGB data and the color conversion information are sent to the color conversion means 24. The color conversion unit 24 converts the target photographic original RGB data using a lookup table indicated by the color conversion information, and generates photographic original CMYK data. The management unit 22 creates a file name, attaches the file name to the generated photographic original CMYK data, and stores it in the image data storage unit 23 (S103). Further, for example, the correspondence relationship in which the file name of the photographic original CMYK data is associated with the file name of the photographic original RGB data is written in the database 25 (see FIG. 2) (S104).

  Next, the operator operates the input means 20 to activate the program, and creates layout image data in which the photographic original CMYK data is laid out. For example, the input unit 20 is used to instruct the photographic original CMYK data to be laid out and the arrangement position (S201, Y).

  The layout unit 27 creates layout image data in which photographic original CMYK data is arranged (S202). The layout image data includes layout image data identification information (such as a file name), photographic document CMYK data layout information, and photographic document CMYK data to which identification information is attached (see FIG. 3). The layout image data is stored in the memory 28, and the display control means 30 causes the display means 29 to display an image based on the layout image data (see FIG. 4) (S203).

  Here, when the input menu screen is displayed on the display unit 29 using the input unit 20 and a print instruction is input (S206, Y), the RIP processing unit 31 converts the layout image data into raster data (bitmap data). The image data for printing is converted to (S207) and sent to the printing apparatus (S208). Then, an image is printed on the printing apparatus based on the printing image data.

  For example, if the operator looks at the printed matter and determines that there is a problem with color conversion, the input menu screen is displayed at that position by right-clicking on the image of the specific photo original CMYK data using the mouse of the input means 20. Then, color conversion information for re-conversion is selected and an instruction for re-conversion is input. The management means 22 receives this re-conversion instruction (S205, Y), specifies the photo original CMYK data designated for re-conversion based on the information indicating the right-clicked position and the layout information of the layout image data, The photographic original RGB data corresponding to the photographic original CMYK data specified with reference to the database 25 is discriminated, the photographic original RGB data is read from the image data storage means 23, and color conversion is performed together with color conversion information for reconversion. The data is sent to the means 24 (S209).

  The color conversion unit 24 converts the photographic original RGB data sent from the management unit 22 using a lookup table stored in the LUT storage unit 26 indicated by the reconversion color conversion information, and generates photographic original CMYK data. (S210).

  Then, the layout unit 27 replaces the photographic original CMYK data for which re-conversion of the layout image data has been instructed with the photographic original CMYK data obtained by the re-conversion (S211). When a print instruction is input from the input unit 20 (S206, Y), the image is printed by the printing apparatus in the same manner (S207) (S208). If the operator looks at the printed matter and determines that there is a problem with the color conversion, the re-conversion is repeated. If there is no problem, for example, the program ends (S204, Y), and this procedure ends.

  As described above, photographic original RGB data is stored, and correspondence between the photographic original CMYK data and the photographic original RGB data from which the color conversion is performed is stored, so that the photograph arranged in the layout image data is stored. Photo original RGB data corresponding to the original CMYK data can be managed. As a result, when the color of the photographic original CMYK data is reconverted, it is possible to automatically read out the photographic original RGB data that is the source of the conversion, and the reconversion can be easily performed.
