  In the present embodiment, three types of reflection attributes are defined as the reflectance. Specifically, in the present embodiment, the reflectance includes a specular light reflectance, a diffused light reflectance, and an ambient light reflectance. The specular light reflectance is a reflectance at which the incident angle and the reflection angle are equal. The diffused light reflectance is a reflectance for irregular reflection. The ambient light reflectance is a reflectance of light obtained by repeated irregular reflection. The reflection color and reflection intensity of each of the specular light reflectance, diffuse light reflectance, and environmental light reflectance are set according to the values of RGB components in the document data. Specifically, in FIG. 3, “(0.5, 0.5, 0.5)” described as an example of the value of the specular light reflectance is the specular light of each of the R component, the G component, and the B component. It shows that the reflectance is “0.5”.

  Note that the reflectance varies depending on the type of paper quality of the recording medium to be printed according to the document data. In the present embodiment, description will be made assuming that the reflectance of each wavelength is the same depending on the type of paper quality.

  The observation environment management table is information that defines light source information indicating light attributes corresponding to observation environment information indicating the observation environment.

  FIG. 4 is a diagram illustrating an example of the data structure of the observation environment management table. The observation environment management table is information in which observation environment information and light source information are associated with each other. Note that the observation environment management table only needs to be information in which observation environment information and light source information are associated with each other, and may be a database or a table, and the data format is not limited.

  The light source information is information indicating the light attribute of the observation environment in the real space specified by the corresponding observation environment information. The light attribute is information for specifying a light source and a reflection amount for producing light at the time of displaying a preview image.

  In the present embodiment, the light source information includes a color temperature. The color temperature is the color temperature of the light source in the observation environment specified by the corresponding observation environment information. The color and brightness indicated by the color temperature can be expressed by the light amount or luminance for each RGB color component. Then, the amount of reflection for rendering the light when displaying the preview image is determined by the product of the light amount of the light source (light source information) and the reflectance of the object (value shown in FIG. 3 above). FIG. 4 shows light amount (luminance) (mirror surface light amount, diffused light amount, environmental light amount) for each RGB color component, which is an item relating to color temperature, as light source information. In this embodiment, the light source type of the light source, the arrangement position of the light source, and the direction of the light source are described as being fixed.

  Each value is input to the observation environment management table according to an operation instruction of the input unit 18 by the user, and is stored in the storage unit 16. Further, the observation environment management table can be updated as appropriate according to an operation instruction of the input unit 18 by the user.

  The observation environment management table is information that defines color temperature (unit “K”) and reflectance (specular light reflectance, diffused light reflectance, ambient light reflectance) indicating the color temperature as light source information. It may be.

  FIG. 5 is a diagram illustrating an example of a data structure different from that in FIG. 4 of the observation environment management table. As shown in FIG. 5, the observation environment management table may be information that defines the color temperature and the light amount (specular light amount, diffused light amount, environmental light amount) that is an item related to the color temperature as the light source information.

  For example, when the observation environment information and the corresponding color temperature are input according to the operation instruction of the input unit 18 by the user, the display processing unit 14 associates the input observation information and the color temperature with the observation environment. Register in the management table. Then, the display processing unit 14 uses a known calculation formula from the registered color temperature, and as light source information, the light amount for each RGB color component (specular light amount, diffused light amount, environmental light amount), which is an item related to the color temperature. ) May be calculated and registered in the observation environment management table. In this case, the user can register the reflection amount, which is an item related to the color temperature, in the observation environment management table by setting the color temperature corresponding to the observation environment information according to the operation instruction of the input unit 18.

  The edit management table is information that defines display color edit information. FIG. 6 is a diagram illustrating an example of the data structure of the edit management table. The edit management table is information in which edit identification information (hereinafter referred to as edit ID), an edit name, and edit information are associated with each other. The edit management table may be any information that defines edit information, and may be a database or a table, and the data format is not limited.

  The edit ID is information for identifying the correspondence between the edit name and the edit information. The edit name is the name of the edit corresponding to the edit information.

  The edit information is information that defines the edit value of the display color. The display color indicates the display color when the preview image is displayed on the display unit 20. In the present embodiment, the preview image includes a document display surface. The document display surface is obtained by setting the light attribute corresponding to the observation environment information designated by the user on the document surface on which the document data is displayed. The display color indicates the display color of the original display surface.

  In the present embodiment, the edit value of the display color includes a tint adjustment value, a brightness adjustment value, and the like. The edit value of the display color may include another edit value (for example, a gamma correction value) related to the display color.

  The brightness adjustment value is a value indicating the brightness of the display color.

  The color adjustment value is indicated by a parameter indicating the strength of each color component for adjusting the color. In this embodiment, as an example, a case will be described in which the color adjustment value is represented by a coefficient relating to “redness” (denoted as coefficient s) and a coefficient relating to “blueness” (denoted by coefficient t). Note that the adjustment value of the color is not limited to reddish and blued, but may further include coefficients relating to colors other than reddish and blued.

  The edit management table can be updated as appropriate according to an operation instruction of the input unit 18 by the user.

  For example, the user inputs a color adjustment value in advance via a color adjustment screen or the like. FIG. 7 is a schematic diagram illustrating an example of an adjustment screen 60 for inputting a color adjustment value.

  As shown in FIG. 7, the adjustment screen 60 includes a slide bar 60B and a thumb 60A indicating the adjustment position on the slide bar 60B. A “red” character is displayed on one end side of the slide bar 60B in the extending direction, and a “blue” character is displayed on the other end side.

  The user can adjust the coefficient “s” related to “redness” and the coefficient “t” related to “blueness” by adjusting the position of the thumb 60A on the slide bar 60B. According to an operation instruction of the input unit 18, the user may increase redness as the thumb 60A is positioned on the “redness” side in the extending direction of the slide bar 60B, and increase blueness as the thumb 60A is positioned on the “blueness” side. it can.

  The display processing unit 14 obtains the position of the thumb 60A in the extending direction of the slide bar 60B, which is instructed by an operation instruction of the input unit 18 by the user, thereby obtaining a coefficient s regarding “redness” according to the position of the thumb 60A. The coefficient “t” related to “blue” may be acquired as a color adjustment value and registered in the edit management table.

  For example, when the position of the thumb 60A in the extending direction of the slide bar 60B is located in the center of the extending direction, the display processing unit 14 acquires a color adjustment value with coefficient s = coefficient t = 0. In addition, when the position of the thumb 60A is on the “redness” side from the center in the extending direction of the slide bar 60B, the display processing unit 14 keeps the coefficient t = 0 and positions the thumb 60A on the “redness” side end. As the value increases, the value obtained by increasing the value of the coefficient s toward 1.0 (maximum value) is acquired.

  Further, when the position of the thumb 60A is on the “blue” side from the center in the extending direction of the slide bar 60B, the display processing unit 14 keeps the coefficient s = 0 and positions the thumb 60A on the “blue” side end. As the value increases, the value obtained by increasing the value of the coefficient t toward 1.0 (maximum value) is acquired.

  Then, the display processing unit 14 stores the coefficient s related to “redness” and the coefficient t related to “blueness” in the edit management table as color adjustment values.

  Returning to FIG. 1, the description will be continued. The display processing unit 14 mainly performs control to display a preview image of document data on the display unit 20.

  The preview image includes a display surface on which an image obtained by editing the document data is displayed. In the present embodiment, a case will be described in which the preview image is an image in which a display surface on which an image obtained by editing document data or the like is superimposed on a background image (details will be described later). In the present embodiment, the display processing unit 14 realizes display of a preview image by a 3D graphic engine such as OpenGL, for example.

  As described above, the background image is a captured image of the observation environment in the real space where the preview image is displayed. In the present embodiment, the display surface overlaid on the background image is a document display surface. The document display surface is an image in which at least the light attribute of the observation environment is set on the document surface on which document data is displayed. Details of the display processing of the document display surface and the preview image will be described later.

  In the present embodiment, the preview image is a three-dimensional image in which a background image is arranged in a virtual three-dimensional space (hereinafter sometimes referred to as a virtual space), and an original display surface is arranged in the three-dimensional space on the background image. A case where the model is an image projected on a two-dimensional surface will be described.

  In the three-dimensional model, the horizontal direction of the display screen of the display unit 20 is the x axis, the vertical direction is the y axis, and the direction perpendicular to the display screen is the z axis. The preview image may be a two-dimensional model in which a background image and a document display surface are arranged in a two-dimensional space.

  In the present embodiment, the case where the preview image is an image in which the document display surface is arranged on the background image is described. However, the preview image may be an image including the document display surface without including the background image. Further, the preview image may be an image including another display surface.

  As other display surfaces, for example, a display surface on which a transparent image formed using a colorless developer is displayed, or a surface effect image that defines a surface effect applied to paper using a colorless developer is displayed. Although a display surface etc. are mentioned, it is not restricted to these.

  When the preview image includes a plurality of display surfaces, the preview image may be an image in which the plurality of display surfaces are arranged at different positions along the z-axis direction.

  FIG. 8 is a functional block diagram of the display processing unit 14. The display processing unit 14 includes a receiving unit 14A, an editing unit 14B, and a display control unit 14C.

  Part or all of the reception unit 14A, the editing unit 14B, and the display control unit 14C may be realized by causing a processing device such as a CPU to execute a program, that is, by software, or an IC (Integrated Circuit). Such hardware may be used, or software and hardware may be used in combination.

  The accepting unit 14A accepts selection of document data to be displayed and selection of observation environment information. The accepting unit 14A accepts selection of document data, selection of observation environment information, and selection of editing information from the input unit 18.

  For example, the display control unit 14C reads a document management table (for example, see FIG. 2) from the storage unit 16, and displays the document data registered in the document management table on the display unit 20 in a selectable manner. For example, the display control unit 14C displays a list of document names registered in the document management table on the display unit 20 in a selectable manner. The user operates the input unit 18 to select the document name of the document data to be displayed from the displayed list of document names. The input unit 18 outputs a signal indicating the document name selected by the user to the display processing unit 14. The receiving unit 14A of the display processing unit 14 receives selection of document data to be displayed by reading document data corresponding to information indicating the document name received from the input unit 18 from the document management table.

  Further, for example, the display control unit 14C reads an observation environment table (see, for example, FIG. 4) from the storage unit 16, and displays a list of observation environment names of observation environment information registered in the observation environment table on the display unit 20. To do. The user operates the input unit 18 to select an environment for observing the preview image from the displayed list of observation environment names. The input unit 18 outputs a signal indicating the observation environment name selected by the user to the display processing unit 14. The receiving unit 14A of the display processing unit 14 receives the selection of the observation environment information by reading the observation environment information of the observation environment name received from the input unit 18 from the observation environment table.

  Further, for example, the display control unit 14C reads the edit management table (for example, see FIG. 6) from the storage unit 16, and displays a list of edit names corresponding to the edit information registered in the edit management table on the display unit 20. To do. The user operates the input unit 18 to select an edit name for editing the display color of the document data from the displayed list of edit names. The input unit 18 outputs a signal indicating the edit name selected by the user to the display processing unit 14. The receiving unit 14A of the display processing unit 14 receives selection of editing information by reading editing information corresponding to the editing name received from the input unit 18 from the editing management table.

  Note that an adjustment value (a color adjustment value or a brightness adjustment value) indicated by the editing information may be input according to an operation instruction of the input unit 18 by the user. In this case, for example, when an instruction area for instructing input of predetermined new editing information on the display unit 20 is instructed by an operation instruction of the input unit 18 by the user, the display control unit 14C displays the adjustment screen 60. (See FIG. 7) may be displayed on the display unit 20. Then, when the position of the thumb 60A on the adjustment screen 60 is adjusted by an operation instruction of the input unit 18 by the user, the receiving unit 14A receives information indicating a color adjustment value according to the adjusted position. The accepting unit 14A accepts an edit name corresponding to the color adjustment value from the input unit 18 via an input screen (not shown). Then, the reception unit 14A associates the received color adjustment value with the edit name and registers them in the edit management table. Further, the receiving unit 14A may receive the input color adjustment value as a selection of editing information.

  Then, the reception unit 14A stores the received information in the storage unit 16 as selection status information indicating a selection status by the user. The accepting unit 14A clears the selection status information every time a preview image is displayed by a process described later.

  FIG. 9 is a diagram illustrating an example of a data structure of selection status information. The selection status information is information in which the document ID of the display target document data received by the reception unit 14A, the environment ID of the received observation environment information, and the edit ID of the received editing information are associated with each other. Note that the selection status information may be actual data (original data, observation environment information, editing information) corresponding to each of these IDs.

  When at least one of the document data to be displayed, the observation environment information, and the editing information is changed or updated by an operation instruction of the input unit 18 by the user, the reception unit 14A registers the latest selected information. The selection status information is updated as appropriate.

  Returning to FIG. 8, the editing unit 14B uses the editing information received by the receiving unit 14A to generate edited document data by editing the display target document data received by the receiving unit 14A. Specifically, the editing unit 14B reads the document data corresponding to the document ID registered in the selection status information (see FIG. 9) from the document management table of the storage unit 16, thereby allowing the editing unit 14A to accept the editing. Get information. Then, the editing unit 14B generates edited document data.

  For example, it is assumed that the reception unit 14A receives a color adjustment value including a coefficient s relating to “redness” and a coefficient t relating to “blueness” as editing information.

  In this case, the editing unit 14B corrects each RGB color value (pixel value) of each pixel of the received document data using each of the following formulas (1) to (3).

R = (1-t) r (1)
G = (1-s−t) g Formula (2)
B = (1-s) b Formula (3)

  Expression (1) is an expression indicating correction of the color value (pixel value) of the R color component of each pixel. In Expression (1), “R” indicates the color value of the R (red) color component of the edited document data (corrected document data). In Expression (1), “r” indicates the color value of the R (red) color component of the document data.

  Expression (2) is an expression indicating correction of the color value (pixel value) of the G color component of each pixel. In equation (2), “G” indicates the color value of the G (green) color component of the edited document data (corrected document data). In Expression (2), “g” indicates the color value of the G (green) color component of the document data.

  Expression (3) is an expression indicating correction of the color value (pixel value) of the B color component of each pixel. In Expression (3), “B” indicates the color value of the B (blue) color component of the edited document data (corrected document data). In equation (3), “b” indicates the color value of the B (blue) color component of the document data.

  In Expressions (1) to (3), “s” is a coefficient s related to “redness”, and “t” is a coefficient t related to “blueness”.

  When the editing information received by the receiving unit 14A includes other adjustment values such as brightness adjustment values and gamma correction values, the editing unit 14B performs editing in accordance with the editing information on the document data. .

  For example, when the editing information further includes a brightness adjustment value, the editing unit 14B adjusts the color according to the received color adjustment value for the document data, and adjusts the received brightness. The edited document data is generated by adjusting the color value of each pixel to the brightness corresponding to the value.

  The display control unit 14C sets the light attribute specified by the light source information corresponding to the received observation environment information on the document surface on which the edited document data that is the document data whose display color has been edited by the editing unit 14B is displayed. Control is performed to display an image including the original display surface on the display unit 20 as a preview image. The preview image is an image obtained by estimating the printing result of the received document data.

  That is, the display control unit 14 </ b> C performs control to generate a preview image and display it on the display unit 20 using a 3D graphic engine (OpenGL in the present embodiment).

  Specifically, first, the display processing unit 14C sets the light attribute specified by the light source information corresponding to the observation environment information received by the receiving unit 14A on the document surface on which the edited document data is displayed. The light attribute is, for example, an attribute specified by the light color of the light source, the position of the light source, and the direction of the light source in the 3D engine. In this embodiment, the position and direction of the light source are set in advance. The color of light from the light source corresponds to the color temperature described above.

  Next, the display control unit 14C sets a normal vector at the time of displaying the document surface, and an arrangement position of the document surface in the virtual three-dimensional space. For example, the display control unit 14 </ b> C reads the normal vector and the arrangement position of the document surface from the storage unit 16. In the present embodiment, it is assumed that the normal vector and the arrangement position of the document surface are predetermined and stored in the storage unit 16.

  Note that the arrangement position of the document surface and the interval between the display surfaces in the case where the preview image includes a plurality of display surfaces may be changed to any interval according to an operation instruction of the input unit 18 by the user.

  Next, the display control unit 14C texture-maps the document surface in which the light attribute is set and the edited document data is displayed at the set position of the document surface in the virtual three-dimensional space. Thereby, a document display surface is generated.

  Then, the display control unit 14C arranges the background image (see FIG. 4) included in the received observation environment information behind the document display surface in accordance with the display area of the virtual three-dimensional space. Accordingly, the display control unit 14C performs control to display an image in which the document display surface is superimposed on the background image on the display unit 20 as a preview image in which the print result of the document data is estimated.

  FIG. 10 is a schematic diagram showing a virtual three-dimensional space for constructing a preview image. The display control unit 14C arranges the document display surface 32 in a virtual three-dimensional space S (corresponding to the virtual space S in FIG. 10). Then, the display control unit 14 </ b> C places the background image 30 behind the document display surface 32. In addition, the display control unit 14C arranges the light source L having the color temperature specified by the light source information selected by the user received by the receiving unit 14A in a virtual three-dimensional space. The arrangement position of the light source L may be stored in the storage unit 16 in advance. The light source information (see FIG. 4) may further include a light source arrangement position. In this case, the display control unit 14C arranges the light source L having the color temperature specified by the light source information received by the receiving unit 14A at the arrangement position specified by the light source information. Further, the light source information may be configured to further include P as the light source type that is the type of the light source. In this case, the display control unit 14C specifies the light source L having the color temperature specified by the light source information received by the receiving unit 14A as the intensity corresponding to the light source type specified by the light source information. What is necessary is just to arrange | position to an arrangement position.

  Then, the display control unit 14C converts the state configured in the virtual space into a two-dimensional image viewed from the viewpoint P using the 3D graphic engine, and displays the preview image 34 on the display unit 20 as a control. Do.

  Next, the flow of display processing executed by the display processing device 10 will be described. FIG. 11 is a sequence diagram illustrating a procedure of display processing executed by the display processing device 10.

  First, when the user operates the input unit 18 and the input unit 18 receives a preview image display instruction, the input unit 18 transmits the display instruction to the reception unit 14A (step S100).

  The accepting unit 14A transmits the accepted display instruction to the display control unit 14C (step S102). When receiving the display instruction, the display control unit 14C reads the document management table (see FIG. 2), the observation environment table (see FIG. 4), and the edit management table (see FIG. 6) (steps S104 to S106).

  Then, the display control unit 14C displays the document data registered in the document management table on the display unit 20 so as to be selectable (step S108). In addition, the display control unit 14C displays a list of observation environment names of the observation environment information registered in the observation environment table on the display unit 20 (step S108). In addition, the display control unit 14C displays a list of edit names registered in the edit management table on the display unit 20 (step S108).

  The user operates the input unit 18 while viewing these lists displayed on the display unit 20 to edit the document data to be displayed, the name of the observation environment for observing the preview image, and the edit for editing the display color. Select a name. Thereby, the accepting unit 14A accepts selection of document data to be displayed, selection of observation environment information, and selection of editing information from the input unit 18 (step S110).

  The receiving unit 14A associates the document ID corresponding to the received document data, the environment ID corresponding to the received observation environment information, and the edit ID corresponding to the received editing information, and stores the selected information as selection status information. (Step S112) (see FIG. 9).

  It should be noted that the processing of step S108 to step S112 is performed by displaying a list, selecting by operating the input unit 18 of the user, and accepting each of selection of document data, selection of observation environment information, and selection of editing information. A series of processes of reception by the unit 14A may be sequentially performed.

  The accepting unit 14A transmits an editing signal including the document ID and the editing ID stored in the selection status information (see FIG. 9) in step S112 to the editing unit 14B (step S114).

  When the editing signal received from the receiving unit 14A does not include an editing ID, the editing unit 14B performs the processes of steps S116 to S124 (see A in FIG. 11).

  In this case, the editing unit 14B first transmits an edit information acquisition request to the display control unit 14C (step S116).

  Upon receiving the acquisition request, the display control unit 14C displays, for example, the adjustment screen 60 (see FIG. 7) on the display unit 20 (step S118). When the position of the thumb 60A on the adjustment screen 60 is adjusted by an operation instruction of the input unit 18 by the user, the receiving unit 14A receives information indicating a color adjustment value corresponding to the adjusted position (step S120). . The accepting unit 14A accepts an edit name corresponding to the color adjustment value from the input unit 18 via an input screen (not shown) (step S120).

  Then, the reception unit 14A associates the received color adjustment value with the edit name and registers them in the edit management table. At this time, the display control unit 14C may further display a brightness adjustment screen. In this case, the reception unit 14A may acquire the brightness adjustment value and register it in the edit management table. Then, the receiving unit 14A registers the received editing surface in the editing management table in association with the newly registered editing information (for example, the tint adjustment value and the brightness adjustment value), and the new editing ID. Is added to update the edit management table (see FIG. 6). Further, the receiving unit 14A registers the edit ID corresponding to the edit information newly registered in the edit management table in the selection status information (see FIG. 9) (step S122).

  Next, the reception unit 14A transmits the newly registered editing information to the editing unit 14B (step S124).

  By the processing in these steps S116 to S124, new edit information is received, registered (updated) in the edit management table, and registered in selection status information.

  Next, the editing unit 14B generates edited document data obtained by editing the document data corresponding to the document ID received in step S114, using the editing information received in step S114 (or step S124) (step S126).

  By the processing in step S126, the display color when the document data is displayed is edited to the display color indicated by the editing information instructed by the user.

  Next, the editing unit 14B transmits the edited document data obtained by editing the display color of the document data to the display control unit 14C (step S128).

  The display control unit 14 </ b> C reads the environment ID registered in the selection status information stored in the storage unit 16. Then, the display control unit 14C reads the light source information corresponding to the environment ID and the background image corresponding to the environment ID from the observation environment table (see FIG. 4 or FIG. 5) (steps S130 to S132).

  Next, the display control unit 14C sets the light attribute specified by the light source information read in steps S130 to S132 on the original image on which the background image and the edited original data received in step S128 are displayed. The display and the superimposed preview image 34 are controlled to be displayed on the display unit 20 (steps S134 and S136).

  After the preview image 34 is displayed on the display unit 20, an adjustment value (a color adjustment value or a brightness adjustment value) indicated by the editing information is further input by an operation instruction of the input unit 18 by the user. It may be possible. In this case, for example, when an instruction area for instructing input of predetermined new editing information on the display unit 20 is instructed by an operation instruction of the input unit 18 by the user, the display control unit 14C displays the adjustment screen 60. (See FIG. 7) may be displayed on the display unit 20. And what is necessary is just to perform the process of step S118-step S136.

  Further, when executing the process of step S100 again after executing the process of step S136, in the display processing device 10, the receiving unit 14A clears the selection status information (see FIG. 9) stored in the storage unit 16, and the step The process is executed from S100. For this reason, in the present embodiment, the selection status information is cleared every time the preview image 34 is displayed.

  As described above, in the display processing apparatus 10 according to the present embodiment, the storage unit 16 has the document data, the light source information indicating the light attribute corresponding to the observation environment information indicating the observation environment, the display color editing information, and the like. Are stored in advance. The accepting unit 14A accepts selection of document data to be displayed, selection of observation environment information, and selection of editing information. The editing unit 14B uses the received editing information to generate edited document data obtained by editing the display color of the received document data. The display control unit 14C prints the received document data, including an image including a document display surface in which the light attribute specified by the light source information corresponding to the received observation environment information is set on the document surface on which the edited document data is displayed. Control is performed to display the result on the display unit 20 as the estimated preview image 34.

  As described above, in the display processing apparatus 10 of the present embodiment, the document data, the light source information, and the editing information are individually stored, and the document data, the light source information, and the editing information selected by the user are stored. The display color is adjusted and the preview image 34 is displayed using.
