  Hereinafter, embodiments of a display processing device, a display processing method, and a program will be described in detail with reference to the accompanying drawings.

(First embodiment)
FIG. 1 is a schematic diagram of a display processing apparatus 10 according to the present embodiment.

  The display processing device 10 is a device that controls display of a preview image. The display processing device 10 may be a portable portable terminal or a fixed terminal.

  The display processing device 10 includes a photographing unit 12, a display processing unit 14, a storage unit 16, an input unit 18, and a display unit 20. The photographing unit 12, the display processing unit 14, the storage unit 16, the input unit 18, and the display unit 20 are electrically connected by a bus 22.

  Note that the display processing device 10 may be configured to include at least the display processing unit 14 and the storage unit 16, and has a configuration in which at least one of the imaging unit 12, the input unit 18, and the display unit 20 is provided as a separate body. There may be.

  The photographing unit 12 photographs the observation environment in the real space of the preview image displayed on the display unit 20. Thereby, the imaging unit 12 acquires a background image as a captured image of the observation environment in the real space. The observation environment observed by the user is, for example, an office, an exhibition hall, a station premises, a station platform, or various buildings.

  The imaging unit 12 is a known imaging device. The photographing unit 12 performs photographing of the observation environment and obtains a background image when the photographing is instructed by an operation instruction of the input unit 18 by the user. Note that the display processing device 10 may be configured not to include the photographing unit 12. In this case, the background image may be stored in the storage unit 16 in advance.

  The input unit 18 receives various operations from the user. The input unit 18 is, for example, a voice recognition using a mouse or a microphone, a button, a remote control, a keyboard, or the like.

The display unit 20 displays various images. The display unit 20 is a known display device such as an LCD (Liquid Crystal Display) or a projector that projects an image.
In the present embodiment, a preview image to be described later is displayed on the display unit 20.

  In addition, it is good also as a touch panel which comprised the input part 18 and the display part 20 integrally.

  The display processing unit 14 is a computer including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The display processing unit 14 controls each unit provided in the display processing device 10. The display processing unit 14 may be configured by a circuit other than the CPU.

  In the present embodiment, the display processing unit 14 performs display control using a 3D graphic engine such as OpenGL (Open Graphics Library).

  The storage unit 16 is a storage medium such as a memory or a hard disk drive (HDD), and stores various programs and various data for executing processes described later.

  In the present embodiment, the storage unit 16 stores a texture information table and environmental history information in advance.

  FIG. 2 is a schematic diagram illustrating an example of the data structure of the texture information table. The texture information table is a table in which texture information is associated with reflection information. The texture information table is not limited to the data format of the table as long as the texture information and the reflection information are associated with each other. For example, the texture information table may be a database.

  The texture information is information indicating the texture (visual effect) used when displaying the preview image. In the present embodiment, the texture information is described as indicating the type of paper quality of the recording medium to be image formed.

  The type of paper quality is determined in advance for each type so that the difference in paper quality is confirmed by the user when viewing the paper on which the image is formed. In the present embodiment, the paper quality types include mirror-coated paper, gloss paper, matte paper, and the like, but other types may be included.

  The reflection information corresponding to the texture information is information used to express the texture corresponding to the corresponding texture information (that is, the type of paper quality of the image formation target paper). The reflection information includes, for example, specular reflection, diffuse reflection, environmental reflection, self-light emission, and specular reflection index.

  Specular reflection indicates the reflection intensity of specular reflection. The diffuse reflection indicates the reflection intensity of diffuse reflection. The environmental reflection indicates the reflection intensity of the environmental reflection.

  Self-emission indicates the amount of light emitted from the object itself. The amount of light indicated by the self-emission is not used in normal preview image display, but may be used as an effect when the paper on which the image is to be formed is a paper type that contains a large amount of fluorescent brightening agent.

  The specular reflection index is a parameter for controlling the attenuation of the amount of light according to the distance between the display surface pseudo-arranged in the three-dimensional space in the preview image and the light source supported by the display processing unit 14. is there.

  In the present embodiment, a case where the texture information table is stored in the storage unit 16 in advance will be described. Note that each piece of information registered in the texture information table can be updated appropriately according to an operation instruction of the input unit 18 by the user.

  The environmental history information is information indicating the history of environmental information input or set in the past. The environmental information includes a background image, a light source position, a light source effect, and brightness.

  The environment information may be information including at least the light source effect and the brightness. In the present embodiment, a case will be described in which the environment information includes a background image, a light source position, a light source effect, and brightness.

  FIG. 3 is a diagram illustrating an example of the data structure of environment history information. The environment history information is information in which environment identification information (hereinafter referred to as environment ID), environment name, background image, light source position, light source effect, and brightness are associated with each other. The environment history information may be a database or a table, and the data format is not limited.

  The environment ID is information for uniquely identifying the corresponding environment name, background image, light source position, light source effect, and brightness. The environment name indicates the name of an observation environment in which a user observes a print image in which document data is formed on paper or a preview image in which a print result of document data is estimated.

  The document data indicates image data of a print target or a preview image display target whose print result is estimated. The background image is a background image of the observation environment specified by the corresponding observation environment name. The environment history information may be in a form that does not include a background image. In this case, the background image may be separately stored in the storage unit 16. Further, the background image may be an image acquired from the photographing unit 12, or may be information acquired from an external device (not shown).

  The light source position indicates the position of the light source in the three-dimensional virtual space according to the observation environment specified by the corresponding observation environment name. As shown in FIG. 3, the light source position is represented by three-dimensional coordinates (XYZ coordinates). The light source position is indicated by a unit (for example, cm) in real space, for example. This takes into account the ease of setting by the user.

  The light source effect indicates the effect of light that the light source arranged in the three-dimensional virtual space (hereinafter simply referred to as virtual space) gives to the document surface of the document data to be displayed. The document surface represents a display image in which document data is displayed in a virtual space.

  In the present embodiment, the light source effect is represented by an intensity ratio between the intensity of direct light from the light source arranged in the virtual space to the document surface and the intensity of indirect light from the light source to the document surface.

  Direct light is light that is emitted from a light source such as the sun, a spotlight, or a fluorescent lamp, and reaches the document surface directly. Indirect light is light that reaches the document surface after being irradiated from a light source and reflected by another object or the like. For this reason, the higher the intensity of the direct light, the stronger the reflection of the light emitted from the light source on the original surface, and the lower the intensity of the direct light, the weaker the reflection of the light on the original surface. On the other hand, since indirect light is scattered, brightness is also given to an area on the document surface that is not irradiated with direct light. Therefore, the stronger the indirect light intensity, the brighter the original surface, and the lower the indirect light intensity, the darker the original surface.

  In the example shown in FIG. 3, “direct light“ 1.0 ”” and “indirect light“ 1.0 ”” as light source effects corresponding to the environment name “office” include direct light and indirect light. The intensity ratio is 1.0 to 1.0.

  The brightness indicates the brightness of light irradiated on the document surface from the light source arranged in the virtual space. That is, the brightness indicates the overall brightness of the document surface.

  Note that each of the background image, the light source position, the light source effect, and the brightness corresponding to each environment name can be appropriately changed by an operation instruction of the input unit 18 by the user.

  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.

  In the present embodiment, the display surface overlaid on the background image is a document display surface. The document display surface is an image obtained by setting the light attribute of the observation environment on the document surface on which the document data is displayed, and converting the document surface with the light attribute into a two-dimensional image viewed from the viewpoint position. Details of the display processing of the document display surface and the preview image will be described later.

  In the present embodiment, a case will be described in which the preview image is an image in which a document display surface is arranged on a background image. However, the preview image may be an image including the document display surface and may have a form not 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 in the virtual space.

  FIG. 4 is a functional block diagram of the display processing unit 14.

  The display processing unit 14 includes a first acquisition unit 14A, a second acquisition unit 14B, a calculation unit 14C, a display control unit 14D, a third acquisition unit 14E, and an adjustment unit 14F.

  Part or all of the first acquisition unit 14A, the second acquisition unit 14B, the calculation unit 14C, the display control unit 14D, the third acquisition unit 14E, and the adjustment unit 14F cause a processing device such as a CPU to execute a program, for example. That is, it may be realized by software, may be realized by hardware such as IC (Integrated Circuit), or may be realized by using software and hardware in combination.

  The first acquisition unit 14A acquires document data to be displayed. The display target means a target to be displayed as a preview image.

  The first acquisition unit 14A acquires, for example, document data instructed by the operation of the input unit 18 by the user.

  For example, the display control unit 14 </ b> D displays a list of document data stored in the storage unit 16 on the display unit 20. The user selects the document data to be displayed by operating the input unit 18 while referring to the displayed document data list. The input unit 18 outputs identification information of the selected document data to the display processing unit 14. The third acquisition unit 14 </ b> E of the display processing unit 14 acquires the document data by reading the document data corresponding to the identification information acquired from the input unit 18 from the storage unit 16.

  The first acquisition unit 14A may acquire document data from a communication unit (not shown) from an external device (not shown).

  The first acquisition unit 14A stores the acquired document data in the storage unit 16 as display target document data.

  Further, the first acquisition unit 14A may further acquire texture information. In this case, the first acquisition unit 14A acquires document attribute information including document data to be displayed and texture information of paper (recording medium) on which the document data is printed. The first acquisition unit 14A may acquire the original data to be displayed. However, in the present embodiment, as an example, a case will be described in which the first acquisition unit 14A acquires document attribute information including display target document data and texture information.

  In the present embodiment, the first acquisition unit 14 </ b> A acquires document attribute information from the input unit 18.

  The document data acquisition method by the first acquisition unit 14A is as described above. The acquisition of the texture information by the first acquisition unit 14A may be performed by the following method, for example. For example, the display control unit 14D displays a list of texture information (paper quality types) registered in the texture information table (see FIG. 2) stored in the storage unit 16 in a selectable manner on the display unit 20. When any of the texture information displayed on the display unit 20 is selected by an operation instruction of the input unit 18 by the user, the input unit 18 outputs the selected texture information to the first acquisition unit 14A. The first acquisition unit 14A acquires the texture information received from the input unit 18.

  The second acquisition unit 14B acquires environment information. The environmental information includes the first brightness and the first intensity ratio.

  The brightness indicates the brightness of light emitted from the light source arranged in the virtual space to the document surface of the document data to be displayed arranged in the virtual space. The first brightness indicates brightness and is brightness included in the environment information acquired by the second acquisition unit 14B.

  The intensity ratio indicates the light source effect that the light source arranged in the virtual space gives to the document surface, and indicates the intensity ratio between the direct light intensity from the light source to the document surface and the indirect light intensity. The first intensity ratio is an intensity ratio that indicates the intensity ratio (that is, the light source effect) and is included in the environmental information acquired by the second acquisition unit 14B.

  For example, the second acquisition unit 14B acquires environment information instructed by an operation of the input unit 18 by the user. Specifically, the display control unit 14D performs control to read environment history information (for example, see FIG. 3) from the storage unit 16 and display it on the display unit 20 in a selectable manner. The user operates the input unit 18 to select a desired environment ID or environment name from the displayed environment history information. The input unit 18 outputs the received environment ID or environment name to the display processing unit 14. In the second acquisition unit 14B of the display processing unit 14, each of the light source effect (intensity ratio) and brightness corresponding to the environment ID or environment name received from the input unit 18 is stored in the storage unit 16 as environment history information. And obtained as the first intensity ratio and the first brightness.

  The method for acquiring the first brightness and the first intensity ratio is not limited to the method selected from the environment history information.

  For example, the user may be able to input an intensity ratio (first intensity ratio) or brightness (first brightness) as a light source effect by an operation instruction on the input unit 18. In this case, the display control unit 14D may display an optical effect adjustment screen for adjusting the optical effect on the display unit 20, for example.

  FIG. 5 is a diagram illustrating an example of the optical effect adjustment screen 60. The optical effect adjustment screen 60 includes a slide bar 60B and a thumb 60A indicating an adjustment position on the slide bar 60B. A character “direct light” is displayed on one end side in the extending direction of the slide bar 60B, and a character “indirect light” is displayed on the other end side.

  The user can adjust the intensity ratio between “direct light” and “indirect light” by adjusting the position of the thumb 60A on the slide bar 60B. For example, the intensity ratio of “direct light” and “indirect light” can be adjusted to the same value (1.0: 1.0) by positioning the thumb 60A in the center of the extending direction of the slide bar 60B. it can.

  Further, the user increases the ratio of the direct light to the indirect light as the thumb 60A is positioned on the “direct light” side in the extending direction of the slide bar 60B according to the operation instruction of the input unit 18, As the position is increased, the ratio of indirect light to direct light can be increased.

  The input unit 18 acquires the position of the thumb 60A in the extending direction of the slide bar 60B, which is instructed by an operation by the user, and outputs an intensity ratio corresponding to the position of the thumb 60A to the display processing unit 14. The second acquisition unit 14B of the display processing unit 14 may acquire the intensity ratio received from the input unit 18 as the first intensity ratio.

  It should be noted that the relative ratio of the intensity when the direct light is irradiated and when the direct light is not irradiated can be easily set by setting one of the direct light and the indirect light as 1.0. For this reason, the user can easily adjust the intensity ratio by indicating the light source effect not by the actual light intensity value but by the ratio of direct light and indirect light.

  Similarly, the first brightness may be acquired from the input unit 18 via a brightness adjustment screen or the like.

  Then, the second acquisition unit 14B stores the acquired environment information including the first brightness and the first intensity ratio in the storage unit 16 as setting information.

  Note that the second acquisition unit 14B may acquire environment information including a background image and a light source position in addition to the light source effect (first intensity ratio) and the first brightness. In the present embodiment, as an example, a case where the second acquisition unit 14B acquires environment information including a light source effect (first intensity ratio), first brightness, a background image, and a light source position will be described. .

  For example, the second acquisition unit 14B acquires environment information instructed by an operation of the input unit 18 by the user. Specifically, the display control unit 14D performs control to read environment history information (for example, see FIG. 3) from the storage unit 16 and display it on the display unit 20 in a selectable manner. The user operates the input unit 18 to select a desired environment ID or environment name from the displayed environment history information. The input unit 18 outputs the received environment ID or environment name to the display processing unit 14. In the second acquisition unit 14B of the display processing unit 14, each of the light source effect (intensity ratio), brightness, background image, and light source position corresponding to the environment ID or environment name received from the input unit 18 is stored in the storage unit. 16 is read out from the environment history information stored in 16 and acquired as the first intensity ratio, the first brightness, the background image, and the light source position.

  The second acquisition unit 14B stores the acquired environment information in the storage unit 16 as setting information for the document data to be displayed acquired by the first acquisition unit 14A.

  Note that the light source position and the background image acquisition method are not limited to the method selected from the environment history information. For example, a desired light source position is input by the operation of the input unit 18 by the user. The second acquisition unit 14B may acquire the light source position by receiving the light source position from the input unit 18. Further, an image to be used as a background image among images stored in the input unit 18 is selected according to an operation instruction of the input unit 18 by the user. Then, the second acquisition unit 14B may acquire the selected image as a background image, and the second acquisition unit 14B uses the image captured by an operation instruction of the imaging unit 12 by the user as the background image. You may get it.

  The calculation unit 14C calculates color information of the light source according to the first brightness and the first intensity ratio acquired by the second acquisition unit 14B. The calculation unit 14C reads the first brightness and the first intensity ratio included in the setting information stored in the storage unit 16 and calculates color information.

  In the present embodiment, the color information includes specular light color information, diffused light color information, and ambient light color information. Then, the calculation unit 14C calculates a first ratio of direct light to indirect light and a second ratio of indirect light to direct light from the first intensity ratio. For example, when the first intensity ratio between direct light and indirect light is 1.0 to 0.6, the calculation unit 14C calculates 0.625 (a value of 1 / 1.6) as the first ratio. Then, 0.375 (value of 0.6 / 1.6) is calculated as the second ratio.

  Next, the calculation unit 14C calculates each of color information of specular light, color information of indirect light, and color information of ambient light as color information. Specifically, the calculation unit 14C calculates a multiplication value of the first brightness and the first ratio as color information of specular light. In addition, the calculation unit 14C calculates a multiplication value of the first brightness and the first ratio as the color information of the diffused light. In addition, the calculation unit 14C calculates a multiplication value of the first brightness and the second ratio as the color information of the ambient light.

  Specifically, the calculation unit 14C calculates the color information using the following formulas (1) to (3).

Color information of specular light = S × T (1)
Color information of diffused light = S × T (2)
Color information of ambient light = S × K (3)

  In addition, in Formula (1)-Formula (3), S shows brightness. Note that S is 0.0 ≦ S ≦ 1.2. In Formula (1) or Formula (2), T represents the first ratio of direct light to indirect light. T is 0.0 ≦ T ≦ 1.0. Moreover, in Formula (3), K shows the 2nd ratio of indirect light with respect to direct light. K is 0.0 ≦ K ≦ 1.0.

  The calculation unit 14C substitutes the first brightness included in the setting information as the brightness for S in the expressions (1) to (3), and calculates the intensity ratio for T from the first intensity ratio. The color information is calculated by substituting the first ratio and substituting the second ratio calculated from the first intensity ratio for K as the intensity ratio.

  The display control unit 14D performs control to display the preview image on the display unit 20. The preview image is an image obtained by estimating the print result of the document data received as a display target.

  The display control unit 14D 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, when the color information is calculated by the calculation unit 14C, the display control unit 14D first arranges the document surface of the document data to be displayed acquired by the first acquisition unit 14A in the virtual space.

  Then, the display control unit 14D arranges the color light source of the color information calculated by the calculation unit 14C at a predetermined position in the virtual space.

  When the second acquisition unit 14B acquires the environment information including the light source position, the display control unit 14D arranges the light source at the light source position included in the acquired environment information. At this time, as described above, the light source position is shown in units in real space. For this reason, the display control unit 14D converts the acquired unit of the light source position into a unit used in the virtual space, and arranges the light source at the light source position after the unit conversion.

  Further, the display control unit 14D sets reflection information and light attributes corresponding to the acquired texture information on the document surface arranged in the virtual space.

  Specifically, the display control unit 14D displays the reflection information corresponding to the texture information acquired by the second acquisition unit 14B on the original surface on which the original data acquired by the first acquisition unit 14A is displayed, and the second acquisition unit 14B. The light attribute specified by the acquired environment information is set.

  The display control unit 14D acquires reflection information corresponding to the texture information acquired by the second acquisition unit 14B by reading it from the texture information table (see FIG. 2), and sets it on the document surface.

  The light attribute includes the position of the light source, color information indicating the color of the light of the light source, and the direction of the light source in the 3D engine. In the present embodiment, the direction of the light source is set in advance. The display control unit 14D sets the color information calculated by the calculation unit 14C as color information indicating the light color of the light source. In addition, the display control unit 14D sets the light source position included in the environment information acquired by the second acquisition unit 14B as the position of the light source. At this time, unit conversion is performed as described above.

  Next, the display control unit 14D sets a normal vector at the time of displaying the document surface, and an arrangement position of the document surface in the virtual space. For example, the display control unit 14D 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 14D texture-maps the reflection information corresponding to the texture information and the document surface set with the light attribute at a predetermined arrangement position in the virtual space.

  Then, the display control unit 14D performs control for displaying an image including the document display surface obtained by converting the document surface into a two-dimensional image viewed from the viewpoint position on the display unit 20 as a preview image obtained by estimating the print result of the document data. Do. In the present embodiment, as an example, it is assumed that the viewpoint position is located on the normal line of the document surface. Note that the viewpoint position is not limited to that located at the normal line of the document surface.

  A 3D graphic engine may be used to convert a document surface arranged in the virtual space into a two-dimensional image viewed from the viewpoint position.

  In the present embodiment, the display control unit 14D arranges the background image included in the acquired environment information behind the document surface in accordance with the display area of the virtual three-dimensional space. Then, the display control unit 14D superimposes the document surface on the background image. Then, the display control unit 14D prints the document data on the background image including the document display surface obtained by converting the document surface into a two-dimensional image visually recognized from the viewpoint position located at the normal line of the document surface. Control is performed to display the result on the display unit 20 as an estimated preview image.

  For this reason, light from the light source corresponding to the reflectance according to the texture information of the recording medium and the positional relationship between the light source, the document surface, and the viewpoint is set on the document display surface based on the set brightness. It will be reflected. That is, a preview image corresponding to the acquired environment information is displayed on the display unit 20.

  FIG. 6 is a schematic diagram showing a virtual space (virtual three-dimensional space) S for forming a preview image. The display control unit 14D arranges the document surface 31 in the virtual space S. Then, the display control unit 14D sets reflection information corresponding to the acquired texture information and a light attribute on the document surface 31. In addition, the display control unit 14 </ b> D places the background image 30 behind the document surface 31. In addition, the display control unit 14D arranges the light source L in the virtual space at the light source position included in the acquired environment information. The display control unit 14D uses the color information calculated by the calculation unit 14C as the color information of the light source L.

  Then, the display control unit 14D uses the 3D graphic engine to convert the document surface 31 arranged in the virtual space S to the normal line of the document surface 31 (the background image 30 relative to the document display surface 32 on the normal line). Is converted into a two-dimensional image viewed from the viewpoint position P located on the opposite side), and the document display surface 32 is obtained. Then, the display control unit 14D performs control to display an image including the document display surface 32 on the display unit 20 as a preview image 34.

  In the present embodiment, the display control unit 14D displays a two-dimensional image obtained by visually recognizing the document surface 31 disposed in the virtual space S and the background image 30 disposed behind the document surface 31 from the viewpoint position P. Then, control is performed to display on the display unit 20 as the preview image 34 in which the document display surface 32 is arranged on the background image 30.

  7 to 9 are diagrams illustrating an example of the document display surface 32 included in the preview image 34. FIG. 7 to 9 are examples of the preview image 34 in which the first brightness, which is the brightness included in the environment information, is the same, but the values of the first intensity ratios are different from each other.

  Here, as described above, in the present embodiment, the second acquisition unit 14B acquires environment information including the light source effect. In the present embodiment, as described above, the light source effect is the intensity of the direct light from the light source arranged in the virtual space to the document surface and the intensity of the indirect light from the light source to the document surface. Expressed as a ratio. Then, the calculating unit 14C calculates the color information of the light source according to the first brightness that is the brightness included in the acquired environment information and the first intensity ratio that is the intensity ratio included in the environment information. . Further, the display control unit 14D arranges the light source of the calculated color information color at a predetermined position in the virtual space, and converts the document surface arranged in the virtual space into a two-dimensional image viewed from the viewpoint position. An image including the display surface 32 is used as the preview image 34.

  For this reason, the original display surface 32 is in a state in which light attributes including the acquired first brightness and the acquired first intensity ratio as the light source effect are set.

  Therefore, for example, when the ratio of the direct light intensity and the indirect light intensity indicated by the first intensity ratio is the same, the display control unit 14D generates, for example, the document display surface 32A illustrated in FIG. . On the document display surface 32A, both the direct light reflection area A on the document display surface 32A and the reflection area (indirect light reflection area) B other than the area on the document display surface 32A are bright. When a recording medium on which document data is printed is arranged directly under a light source, the recording medium is often visually recognized as shown in FIG.

  On the other hand, when the intensity indicated by the first intensity ratio indicates that “the intensity of the direct light> the intensity of the indirect light” (the intensity of the direct light is greater than the intensity of the indirect light), the display control unit 14D, for example, A document display surface 32B shown in FIG. The direct light reflection area A on the document display surface 32B is bright, but the indirect light reflection area B on the document display surface 32B is dark. As described above, the first brightness of the document display surface 32B is the same as that of the document display surface 32A (see FIG. 7). When visually recognizing the recording medium on which the original data is printed, when there are few objects that are irregularly reflected around the recording medium, or when the color of the surrounding wall is difficult to be reflected, the appearance shown in FIG. On the other hand, the recording medium is often visually recognized.

  Further, when the intensity indicated by the first intensity ratio indicates “direct light intensity <indirect light intensity” (the direct light intensity is weaker than the indirect light intensity), the display control unit 14D displays, for example, FIG. A document display surface 32C shown in FIG. The direct light reflection area A on the document display surface 32C is darker than in FIGS. 7 and 8, and the indirect light reflection area B is brighter than in FIGS. As described above, the first brightness of the document display surface 32C is the same as that of the document display surface 32A (see FIG. 7). When the recording medium on which the document data is printed is visually recognized outside in a cloudy sky, it is often visually recognized as shown in FIG.

  As described above, in the present embodiment, the display control unit 14D can cause the display unit 20 to display the preview image 34 in consideration of the intensity ratio between the direct light intensity and the indirect light intensity.

  Returning to FIG. 4, the third acquisition unit 14 </ b> E acquires an environment information or document attribute information change instruction for the preview image 34 displayed on the display unit 20.

  Specifically, the third acquisition unit 14E includes, for the preview image 34 displayed on the display unit 20, at least one of items (background image, light source position, light source effect, brightness) included in the environment information, or A change instruction for at least one of the items (document data, texture information) included in the document attribute information is acquired.

  For example, the third acquisition unit 14E acquires a brightness change instruction. Specifically, the third acquisition unit 14E acquires a first change instruction. The first change instruction is an instruction to change the brightness (first brightness) used for displaying the preview image 34 to the second brightness. That is, in the present embodiment, among the change instructions, the brightness change instruction will be referred to as a first change instruction. Further, the brightness after change included in the first change instruction will be referred to as second brightness.

  The first change instruction is input through an adjustment screen, for example. For example, it is assumed that a predetermined area for inputting a brightness change instruction in the display processing apparatus 10 is instructed by the user operating the input unit 18. Then, the display control unit 14 </ b> D displays a brightness adjustment screen on the display unit 20.

  FIG. 10 is a diagram illustrating an example of the brightness adjustment screen 62. The brightness adjustment screen 62 includes a slide bar 62B and a thumb 62A indicating an adjustment position on the slide bar 62B. A “bright” character is displayed on one end side in the extending direction of the slide bar 62B, and a “dark” character is displayed on the other end side.

  The user adjusts the overall brightness of the document surface 31 by adjusting the position of the thumb 62A on the slide bar 62B. For example, in accordance with an operation instruction of the input unit 18, the user improves the brightness as the thumb 62 </ b> A is positioned on the “bright” side in the extending direction of the slide bar 62 </ b> B, and the darker the position is positioned on the “dark” side In addition, the brightness can be adjusted.

  The input unit 18 obtains the position of the thumb 62A in the extending direction of the slide bar 62B, which is instructed by an operation by the user, and outputs a value indicating brightness according to the position of the thumb 62A to the display processing unit 14. . The third acquisition unit 14E of the display processing unit 14 acquires the brightness received from the input unit 18 as the second brightness.

  Similarly, the third acquisition unit 14E acquires an instruction to change items other than brightness included in the environment information from the input unit 18. The third acquisition unit 14E acquires an instruction to change each item of the document attribute information from the input unit 18.

  Returning to FIG. 4, when the third acquisition unit 14 </ b> E acquires the change instruction, the adjustment unit 14 </ b> F calculates the calculation unit 14 </ b> C and the display so as to regenerate the preview image 34 reflecting each item specified by the change instruction. Controls the control unit 14D.

  Specifically, it is assumed that the change instruction acquired by the third acquisition unit 14E is a first change instruction for changing the brightness of the preview image 34 to the second brightness.

  In this case, when the adjustment unit 14F acquires the first change instruction, the adjustment unit 14F displays color information according to the second brightness that is the brightness after the change indicated by the first change instruction and the first intensity ratio. The calculation unit 14C is controlled to calculate. That is, for the intensity ratio, the adjustment unit 14F uses the first intensity ratio that is the intensity ratio used for calculating the color information of the document display surface 32 in the preview image 34 currently displayed on the display unit 20, and brightness. For, the calculation unit 14C is controlled to calculate the color information using the second brightness instead of the first brightness.

  Therefore, the calculation unit 14C changes only the brightness to the second brightness indicated by the first change instruction while maintaining the first intensity ratio used when the preview image 34 was displayed last time. To do. Then, the calculation unit 14C calculates new color information using the above formulas (1) to (3) using the first intensity ratio and the second brightness.

  That is, the calculation unit 14C may use the second brightness instead of the first brightness as the brightness S in the calculation of the color information using the above formulas (1) to (3).

  Further, the adjustment unit 14F controls the display control unit 14D so that the preview image 34 using the newly calculated color information is displayed on the display unit 20. For this reason, the display control unit 14D generates the preview image 34 in which the brightness is changed from the first brightness to the second brightness without changing the intensity ratio.

  That is, when the third acquisition unit 14E acquires an instruction to change the brightness of the light source arranged in the virtual space, the display control unit 14D displays the intensity ratio between the intensity of the direct light and the intensity of the indirect light as the light source effect. Is maintained and the first brightness indicated by the environmental information is changed to the second brightness, and the display is controlled on the display unit 20.

  11 to 12 are diagrams illustrating an example of the document display surface 32 with the brightness changed. FIG. 11 shows the brightness set on the original display surface 32A shown in FIG. 7 in which the ratio of the direct light intensity to the indirect light intensity is 1.0 to 1.0. It is a figure which shows an example of the document display surface 32D at the time of changing to 2nd brightness brighter than 1st brightness.

  FIG. 12 shows that the brightness set on the document display surface 32A shown in FIG. 7 in which the ratio of the direct light intensity to the indirect light intensity is 1: 1 is darker than the first brightness of the document display surface 32A. It is a figure which shows an example of the original document display surface 32E at the time of changing to 2nd brightness.

  Each time the third acquisition unit 14E acquires a change instruction, each item included in the change instruction and other items (for example, a background image, a preview image 34 generated in response to the change instruction) A new environment ID and environment name are assigned to the light source position, light source effect, and brightness), and registered in the environment history information (see FIG. 3). Thereby, environment history information is updated at any time.

  Further, when the third acquisition unit 14E acquires an instruction to change the observation environment other than brightness, the adjustment unit 14F displays so as to regenerate the preview image 34 reflecting each item indicated by the change instruction. Controls the control unit 14D.

  In addition, when the 3rd acquisition part 14E acquires the change instruction | indication of a light source effect (ratio of the intensity | strength of direct light and indirect light), the adjustment part 14F is the 2nd intensity ratio which is an intensity ratio after a change, and The calculation unit 14C is controlled to calculate the color information using the first brightness that is the brightness before the change. Then, the display control unit 14D may generate the preview image 34 by the same method as described above using the newly calculated color information.

  When the third acquisition unit 14E acquires an instruction to change document attribute information, the adjustment unit 14F regenerates the preview image 34 using each item (original data, texture information) indicated by the change instruction. Next, the display control unit 14D is controlled.

  Next, the flow of display processing executed by the display processing device 10 will be described. FIG. 13 is a flowchart illustrating a procedure of display processing executed by the display processing device 10.

  First, the first acquisition unit 14A acquires document attribute information from the input unit 18 (step S100). In the present embodiment, the document attribute information includes document data to be displayed and texture information as described above.

  Next, the second acquisition unit 14B acquires environment information (step S102). In the present embodiment, as described above, the environment information includes the first brightness, the first intensity ratio (light source effect), the background image, and the light source position.

  Next, the calculation unit 14C calculates the color information of the light source L according to the first brightness and the first intensity ratio included in the environment information acquired in step S102 (step S104).

  Next, the display control unit 14D uses the document attribute information acquired in step S100, the environment information acquired in step S102, and the color information calculated in step S104 to display the preview image 34 on the display unit 20. Display control is performed (step S106).

  Next, the third acquisition unit 14E determines whether or not the environment information or the document attribute information change instruction has been acquired for the preview image 34 displayed on the display unit 20 in step S106 (step S108). If a negative determination is made in step S108 (step S108: No), the process proceeds to step S116 described later.

  On the other hand, if an affirmative determination is made in step S108 (step S108: Yes), the process proceeds to step S110.

  In step S110, the third acquisition unit 14E determines whether or not the change instruction acquired in step S108 is a first change instruction that is a brightness change instruction (step S110). If an affirmative determination is made in step S110 (step S110: Yes), the process proceeds to step S112.

  In step S112, the adjustment unit 14F has the second brightness that is the brightness after change indicated by the first change instruction as the change instruction acquired in step S108, and the first intensity included in the environment information acquired in step S102. The calculation unit 14C is controlled so as to calculate the color information corresponding to the ratio (step S112).

  Next, the adjustment unit 14F controls the display control unit 14D to display the preview image 34 using the color information newly calculated in step S112 on the display unit 20 (step S114). For this reason, the display control unit 14D displays the preview image 34 on the display unit 20 without changing the intensity ratio and changing the brightness from the first brightness to the second brightness.

  Next, the display processing unit 14 determines whether or not to end the display process (step S116). For example, the display processing unit 14 performs the determination in step S116 by determining whether or not a signal indicating the end of the display process has been received from the input unit 18. A signal indicating the end of the display processing is output from the input unit 18 to the display processing unit 14 when a predetermined area in the display processing device 10 is instructed by an operation of the input unit 18 by the user, for example. The display processing unit 14 may perform the determination in step S116 by determining whether or not this signal has been received.

  If an affirmative determination is made in step S116 (step S116: Yes), this routine ends. On the other hand, if a negative determination is made in step S116 (step S116: No), the process returns to step S100. If a negative determination is made in step S116 (step S116: No), the process may return to step S108.

  On the other hand, if a negative determination is made in step S110 (step S110: No), the process proceeds to step S118. In step S118, the third acquisition unit 14E determines whether an instruction to change observation environment other than brightness is acquired in step S108 (step S118). If a positive determination is made in step S118 (step S118: Yes), the process proceeds to step S120.

  In step S120, the adjustment unit 14F controls the display control unit 14D to regenerate the preview image 34 reflecting each item indicated by the change instruction (step S120). Then, the process proceeds to step S116. In addition, when the 3rd acquisition part 14E acquires the change instruction | indication of a light source effect (ratio of the intensity | strength of direct light and indirect light), the adjustment part 14F is the 2nd intensity ratio which is an intensity ratio after a change, and The calculation unit 14C is controlled to calculate the color information using the first brightness that is the brightness before the change. Then, the display control unit 14D may generate the preview image 34 by the same method as described above using the newly calculated color information.

  On the other hand, if a negative determination is made in step S118 (step S118: No), the process proceeds to step S122. In step S122, the third acquisition unit 14E determines whether or not a document attribute information change instruction has been received (step S122). If a negative determination is made in step S122 (step S122: No), the process proceeds to step S116.

  If an affirmative determination is made in step S122 (step S122: Yes), the process proceeds to step S124. In step S124, the adjustment unit 14F controls the display control unit 14D to regenerate the preview image 34 using each item (original data, texture information) indicated by the change instruction (step S124). Then, the process proceeds to step S116.

  As described above, the display processing device 10 according to the present embodiment includes the first acquisition unit 14A, the second acquisition unit 14B, the calculation unit 14C, the display control unit 14D, the third acquisition unit 14E, and the adjustment. Part 14F.

  The first acquisition unit 14A acquires document data to be displayed. The second acquisition unit 14B includes a first brightness of light emitted from the light source L disposed in the three-dimensional virtual space S to the document surface 31 of the document data disposed in the virtual space S, and the light source L serving as the document surface. Environmental information including a first intensity ratio between the intensity of direct light from the light source L to the original surface 31 and the intensity of indirect light as a light source effect applied to the image sensor 31 is acquired. The calculation unit 14C calculates color information of the light source L according to the first brightness and the first intensity ratio. The display control unit 14D arranges the document surface 31 in the virtual space S, arranges the light source L of the color of the calculated color information at a predetermined position, and visually recognizes the document surface 31 from the viewpoint position P. Control is performed to display an image including the original display surface 32 converted into an image on the display unit 20 as a preview image 34 in which the print result of the original data is estimated. The third acquisition unit 14E acquires a first change instruction to the second brightness. The adjustment unit 14F controls the calculation unit 14C to calculate color information according to the second brightness and the first intensity ratio when the first change instruction is acquired, and the preview image using the color information. The display control unit 14D is controlled to display 34 on the display unit 20.

  As described above, in the display processing apparatus 10 according to the present embodiment, the intensity ratio between the intensity of direct light from the light source L to the document surface 31 and the intensity of indirect light as a light source effect that the light source L gives to the document surface 31. Can be displayed on the display unit 20. When the brightness of the light source L is changed, the preview image 34 in which only the brightness is changed is maintained while maintaining the previously set value (first intensity ratio) for the intensity ratio, and the display unit 20 is regenerated. Can be displayed. Therefore, the overall brightness of the document display surface 32 can be adjusted while maintaining the intensity ratio of the light source L on the document display surface 32 included in the preview image 34.

  Therefore, the display processing apparatus 10 of the present embodiment has an effect that it is possible to provide a natural preview image 34 close to the actual observation environment.

  In the present embodiment, as the light source effect that the light source L gives to the document surface 31, an intensity ratio between the intensity of direct light from the light source L to the document surface 31 and the intensity of indirect light is used. Thus, in this embodiment, the light source effect is classified into two types of light, that is, direct light and indirect light. For this reason, it is possible to provide the preview image 34 including the effect of indirect light.

  In addition, the user can easily adjust the overall brightness of the document display surface 32 while maintaining the intensity ratio of the light source L according to the observation environment.

  In the present embodiment, when the third acquisition unit 14E acquires an instruction to change an observation environment other than brightness or an instruction to change document attribute information, the adjustment unit 14F displays each item indicated by the change instruction. The display control unit 14D is controlled so as to regenerate the reflected preview image 34.

  Therefore, the display control unit 14D can regenerate the preview image 34 in which only the items indicated in the change instruction are changed. As a result, for the same environment (environment name or environment ID), the preview image 34 in which the document data, the light attribute, etc. are appropriately changed can be regenerated and displayed on the display unit 20.

  That is, the document attribute information regarding the document data is the same, and various preview images 34 in which at least a part of each item included in the environment information is changed can be easily provided. Similarly, various preview images 34 in which at least a part of each item (original data, texture information) included in the original attribute information relating to the original data is changed can be easily provided with the same environmental information. it can.

  In the present embodiment, the case has been described in which the display processing device 10 is configured to include the imaging unit 12. However, the display processing apparatus 10 may be configured not to include the photographing unit 12. Note that the display processing apparatus 10 is configured to include the imaging unit 12, whereby a background image can be acquired from the imaging unit 12. Therefore, the user can immediately confirm the preview image 34 in which the print result of the document data is estimated at a place where the print result is desired to be observed.

  In addition, by configuring the display processing device 10 to include the photographing unit 12, the display processing device 10 can be applied to a mobile terminal with a camera function, a tablet PC (personal computer) with a camera function, or the like. .

  Note that in the present embodiment, the storage unit 16 has been described as storing the texture information table and the environment history information in advance. However, the storage unit 16 may be configured not to store the texture information table or the environment history information.

  When the texture information table is not stored in the storage unit 16 in advance, the first acquisition unit 14A may acquire the document data as the document attribute information and does not acquire the texture information. Further, the display control unit 14D may be configured not to set the reflection information according to the texture information.

  However, from the viewpoint of providing the preview image 34 in a state closer to the actual observation environment, the form using the texture information is preferable.

  Moreover, although the memory | storage part 16 may be a form which does not memorize | store environmental history information, it is preferable that the memory | storage part 16 memorize | stores environmental history information. Since the storage unit 16 stores the environment history information, the display control unit 14D can provide the user with a history of the environment information selected in the past in a selectable manner.

  Further, in the present embodiment, the case has been described where the environmental information is information including a background image, a light source position, a light source effect, and brightness. However, as described above, the environment information may be information including at least the light source effect and the brightness. However, if the environmental information is information including a background image, a light source position, a light source effect, and brightness, the display control unit 14D obtains a background image acquired by an operation instruction of the input unit 18 by the user, The preview image 34 can be generated using the light source position, the light source effect, and the brightness. For this reason, from the viewpoint of providing the preview image 34 in a state closer to the actual observation environment, it is preferable that the environment information is information including the background image, the light source position, the light source effect, and the brightness.
