  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

[Outline of this embodiment]
Products such as pamphlets, flyers, posters, etc. have different workmanship depending on the usage environment of display devices, printing devices, media, and the like. Accordingly, it is necessary to perform confirmation work for displaying and comparing digital data of a product (hereinafter referred to as “product data”) on a display device in a color system corresponding to the use environment. However, when such a confirmation operation is performed on a display device (tablet or the like) with a limited screen size, it is conceivable to compare it with a tab switching operation or the like, but this is inferior in operability and takes time.

  Therefore, in the present embodiment, a display device that displays one product data in a plurality of display modes is proposed. However, in the following, two display modes are taken as an example of a plurality of display modes, and these will be described as a basic mode and an overlap mode.

  First, the basic mode will be described. The basic mode may be a mode in which any color system such as RGB or CMYK is preset and data is displayed in the color system. Here, the basic mode is a mode for displaying an image (hereinafter referred to as “RGB image”) in which the product data is expressed in the RGB color system. The RGB image is preferably an image reflecting the calibration correction of the display device.

  Next, the overlap mode will be described. The superposition mode may be a mode for displaying data in a color system different from the basic mode. Here, the superposition mode is set to a mode in which the RGB image of the product data is once converted into CMYK for printing and then the converted RGB image is displayed. The RGB image for display has at least a lower saturation than the RGB image of the product data. However, since both are RGB images, the RGB image that has passed through CMYK will be referred to as a “CMYK image” in order to make it easier to distinguish them.

  Here, the superposition mode is a mode for displaying a CMYK image, but is not limited thereto. For example, it is a mode for displaying RGB images for other display devices, CUD (color universal design) images for people who have difficulty in identifying colors, images obtained by rendering image data on the texture of a medium (paper, etc.), etc. Also good. In particular, in a mode that displays an image in which image data is rendered on the texture of the medium, an image that takes into account the observation environment such as the illumination direction or changes in the observation environment with time and season may be displayed. You may display the image which added the sound for showing.

  In addition, although the overlap mode is one here, the overlap mode may be two or more. In that case, a mode for displaying an image expressed in a different color system may be assigned to each. Furthermore, the display mode assigned to the overlapping window 32 may be changeable.

  FIG. 1 is a diagram showing an example of a GUI (Graphic User Interface) displayed by such a display device. As shown in the figure, this GUI includes a normal window 31 such as a web browser screen and an overlapping window 32 displayed in an overlapping manner. In the present embodiment, the normal window 31 is set to the basic mode, and the overlapping window 32 is set to the overlapping mode. That is, if the display color of the image of the product data in the normal window 31 is, for example, RGB color, CMYK color, gray, double tone (including colored gray), or sepia, only the area where the overlapping window 32 is overlapped, These display colors are changed to other display colors and displayed. In the figure, the hatched hatching indicates that the display colors of the apples and the ground in the overlapping window 32 are different from those of the normal window 31.

  In FIG. 1, a thick boundary 33 is also shown between the normal window 31 and the overlapping window 32. However, in general, it is easier to compare the image in the normal window 31 and the image in the overlapping window 32 when the boundary 33 is not thick. Therefore, the thickness of the boundary 33 may be eliminated. FIG. 2 is a diagram showing an example of a GUI when the thickness of the boundary between the normal window 31 and the overlapping window 32 is eliminated. However, in order to move or enlarge / reduce the overlapping window 32, an operation for recognizing and grasping the overlapping window 32 (for example, an operation for aligning the mouse pointer) is required. Therefore, it is preferable to display all or a part of the boundary with no thickness, or display only the portion that does not interfere with the comparison even if the boundary has a thickness. In the figure, boundaries 34 a to 34 d are displayed at the four corners of the overlapping window 32 as an example of a portion that does not interfere with the comparison.

  In this manner, movement and enlargement / reduction operations are performed on the overlapping window 32. At that time, one of two meanings is given to the overlapping window 32. Hereinafter, the case where the first meaning is given to the overlapping window 32 will be described as the first embodiment, and the case where the second meaning is given will be described as the second embodiment. .

[First Embodiment]
(Overview)
The first embodiment is an embodiment in the case where it is given meaning that an image of a region where the window overlaps is always displayed in the overlapping mode on the overlapping window 32.

  FIG. 3 is a diagram illustrating an example of a state when the overlapping window 32 is moved in the first embodiment. In this figure, the overlapping window 32 is moved to the cloud position. Therefore, clouds and sky are displayed in the overlapping window 32. And that the display color is different from the normal window 31 is indicated by hatching.

  Thus, for example, if the basic mode is a mode for displaying RGB images and the superposition mode is a mode for displaying CMYK images, it is possible to know what CMYK image the RGB image of the product data becomes.

  A display system that realizes such display will be described below. As such a display system, two embodiments can be considered from the viewpoint of a method for generating a superimposed image.

(Configuration of the display system of the first embodiment)
FIG. 4 is a block diagram illustrating a configuration example of the display system 10 in the first embodiment. In the display system 10, the server 20 as an example of a holding device includes a product data storage unit 41, a basic mode image generation unit 42, a basic mode image storage unit 43, an overlap mode image generation unit 44, and an overlap mode. An image storage unit 45 and a superimposed image generation unit 46 are included. The client 30 as an example of a display device includes an operation reception unit 48 and an image output unit 49.

  The product data storage unit 41 stores product data. In the present embodiment, product data is used as an example of original data.

  If the product data stored in the product data storage unit 41 is, for example, document data, the basic mode image generation unit 42 performs processing for converting the product data into an image displayed in the basic mode, thereby performing basic processing. Generate a mode image. In the present embodiment, as an example of the first image processing, a process for converting to an image displayed in the basic mode is used, and as an example of the first image, a basic mode image is used.

  The basic mode image storage unit 43 stores the basic mode image generated by the basic mode image generation unit 42.

  The overlay mode image generation unit 44 performs a process of converting the entire product data stored in the product data storage unit 41 or a designated page into an image displayed in the overlay mode, thereby performing an overlay mode image. Is generated. In the present embodiment, as an example of the second image processing, processing for converting into an image displayed in the superposition mode is used.

  The overlap mode image storage unit 45 stores the overlap mode image generated by the overlap mode image generation unit 44.

  The overlapping image generation unit 46 generates an overlapping image by cutting out an image of an area specified by the operation received by the operation receiving unit 48 from the overlapping mode image stored in the overlapping mode image storage unit 45. In the present embodiment, a superimposed image is used as an example of the second image.

  The operation reception unit 48 receives an operation for designating an area on the normal window 31 from the input device 96 (see FIG. 11). As such an operation, first, there is an operation for creating an overlapping window 32 on the normal window 31 (hereinafter referred to as “creation operation”). There is also an operation for moving the overlapping window 32 on the normal window 31 (hereinafter referred to as “moving operation”). Further, there is an operation (hereinafter referred to as “enlargement / reduction operation”) for enlarging or reducing the overlapping window 32 on the normal window 31. Here, such an operation may be performed by pressing a button with a mouse, pressing a touch panel with a finger, pressing a key on a keyboard, or a gesture. In the present embodiment, an operation reception unit 48 is provided as an example of a reception unit that receives designation of an area on the first image.

  The image output unit 49 outputs the basic mode image stored in the basic mode image storage unit 43 to the display mechanism 95 (see FIG. 11) as an image to be displayed in the normal window 31, and displays the image in the overlapping window 32. The superimposed image generated by the superimposed image generation unit 46 is output to the display mechanism 95 (see FIG. 11). At that time, the image output unit 49 adjusts the display position of the overlapping window 32 on the normal window 31 according to which of the creation operation, the movement operation, and the enlargement / reduction operation is received by the operation reception unit 48.

(Operation of the display system of the first embodiment)
FIG. 5 is a flowchart showing an operation example of the display system 10 in the first embodiment. This operation is started when an instruction is given to display a designated page of designated production data among the production data stored in the production data storage unit 41.

  When the operation starts, first, the basic mode image generation unit 42 generates a basic mode image by performing image processing corresponding to the basic mode on the specified page of the specified product data (step) 401). The image processing may be performed on the entire designated product data, but here it is performed only on the designated page. As a result, the basic mode image is stored in the basic mode image storage unit 43.

  Next, the image output unit 49 outputs the basic mode image stored in the basic mode image storage unit 43 to the display mechanism 95 (see FIG. 11) (step 402). Thereby, the display mechanism 95 displays the normal window 31 including the basic mode image.

  On the other hand, the overlap mode image generation unit 44 generates an overlap mode image by performing image processing corresponding to the overlap mode on the specified page of the specified product data (step 403). The image processing may be performed on the entire designated product data, but here it is performed only on the designated page. Thereby, the overlap mode image is stored in the overlap mode image storage unit 45.

  Thereafter, the operation accepting unit 48 accepts an operation on the normal window 31 from the input device 96 (see FIG. 11) (step 404). Then, the type of operation is determined (step 405). Thereby, the determined type of operation is transmitted to the superimposed image generation unit 46.

  It is assumed that the type of operation transmitted to the superimposed image generation unit 46 is an operation for creating the overlapping window 32. In this case, the overlapping image generation unit 46 generates an overlapping image by cutting out the image of the area specified by the creation operation from the overlapping mode image stored in the overlapping mode image storage unit 45 (step 406). Then, the image output unit 49 outputs the overlap image to the display mechanism 95 (see FIG. 11) so that the overlap window 32 including the overlap image is displayed in the area designated by the creation operation on the normal window 31. (Step 407).

  In addition, it is assumed that the type of operation transmitted to the superimposed image generation unit 46 is a movement operation of the overlapping window 32. In this case, the superimposed image generation unit 46 generates an overlapped image by cutting out an image of the area specified by the moving operation from the overlapping mode image stored in the overlapping mode image storage unit 45 (step 408). Then, the image output unit 49 outputs the overlapped image to the display mechanism 95 (see FIG. 11) so that the overlapped window 32 including the overlapped image is displayed in the area designated by the moving operation on the normal window 31. (Step 409). At this time, the display mechanism 95 may erase the overlapping window 32 displayed in the movement source area.

  Furthermore, it is assumed that the type of operation transmitted to the superimposed image generation unit 46 is an enlargement / reduction operation of the overlapping window 32. In this case, the superimposed image generation unit 46 generates an overlapped image by cutting out an image of an area designated by the enlargement / reduction operation from the overlapping mode image stored in the overlapping mode image storage unit 45 (step 410). Then, the image output unit 49 outputs the superimposed image to the display mechanism 95 (see FIG. 11) so that the superimposed window 32 including the superimposed image is displayed in the area designated by the enlargement / reduction operation on the normal window 31. (Step 411). At this time, the overlapping window 32 displayed in the area before enlargement / reduction may be deleted.

  Thereafter, the process returns to step 404, and the operation reception unit 48 receives the operation on the normal window 31 again from the input device 96 (see FIG. 11). Although not shown in the figure, when the operation receiving unit 48 receives an operation for ending the display of the product data, the operation of this flowchart is also ended.

  As described above, in the first embodiment, the server 20 generates a superimposed image, and the client 30 performs server-side processing for calling it from the server 20. This is a simple configuration for generating an initial superimposed image. It is also suitable for large-scale systems such as cloud services.

  However, in the first embodiment, when a general server configuration or a system configuration with network restrictions is adopted, if the size of the product data is large, a problem of processing cost arises. For example, there is a problem of delay due to the necessity of a large amount of memory and delay due to network access. There is also a problem of processing that cannot be prepared in advance. An example of this problem is that the display contents cannot be changed smoothly when a size change such as enlargement / reduction is instructed.

  Thus, for such a problem, a method of sharing the processing on the server side only with the processing on the client side according to the amount of processing load can be considered. As processing on the client side, for example, a (web) application distributed to the client can freely execute arbitrary processing on the client side application, and is compatible with a web browser (GUI in HTML5). For example, switching of JavaScript (registered trademark) or expansion by a dedicated plug-in can be used. It is desirable to arbitrarily switch between the server side processing and the client side processing according to the server, network load, client resource, and the like. As a method for measuring the load here, a known method such as a method using a waiting time for processing can be considered.

(Configuration of the display system of the second embodiment)
FIG. 6 is a block diagram showing a configuration example of the display system 10 in the second embodiment. In the display system 10, the server 20 as an example of a holding device includes a product data storage unit 51. The client 30 as an example of a display device includes a basic mode image generation unit 52, a basic mode image storage unit 53, a superimposed image generation unit 56, an operation reception unit 58, and an image output unit 59. .

  The product data storage unit 51, the basic mode image generation unit 52, the basic mode image storage unit 53, the operation reception unit 58, and the image output unit 59 are respectively the product data storage unit 41 and the basic mode image in the first embodiment. Since it is the same as the generation unit 42, the basic mode image storage unit 43, the operation reception unit 48, and the image output unit 49, description thereof will be omitted.

  The superimposed image generation unit 56 converts the image of the area specified by the operation received by the operation receiving unit 58 out of the basic mode images stored in the basic mode image storage unit 53 into an image displayed in the overlapping mode. By performing the process, a superimposed image is generated. In the present embodiment, as an example of the second image processing, a process of converting into an image displayed in the overlap mode is used, and an overlap image is used as an example of the second image.

(Operation of the display system of the second embodiment)
FIG. 7 is a flowchart showing an operation example of the display system 10 in the second embodiment. This operation is started when an instruction is given to display the designated page of the designated product data among the product data stored in the product data storage unit 51.

  When the operation starts, first, step 501 and step 502 are executed. However, step 501 and step 502 are the same as step 401 and step 402 in FIG.

  Thereafter, the operation reception unit 58 receives an operation on the normal window 31 from the input device 96 (see FIG. 11) (step 503). Then, the type of operation is determined (step 504). Thereby, the determined type of operation is transmitted to the superimposed image generation unit 56.

  It is assumed that the type of operation transmitted to the superimposed image generation unit 56 is a creation operation of the overlapping window 32. In this case, the superimposed image generation unit 56 cuts out the image of the area specified by the creation operation from the basic mode image stored in the basic mode image storage unit 53, and performs image processing corresponding to the overlapping mode on this image. By doing so, a superimposed image is generated (step 505). Then, the image output unit 59 outputs the overlap image to the display mechanism 95 (see FIG. 11) so that the overlap window 32 including the overlap image is displayed in the area designated by the creation operation on the normal window 31. (Step 506).

  In addition, it is assumed that the type of operation transmitted to the superimposed image generation unit 56 is a movement operation of the overlapping window 32. In this case, the superimposed image generation unit 56 cuts out the image of the area specified by the moving operation from the basic mode image stored in the basic mode image storage unit 53, and performs image processing according to the overlapping mode on this image. By doing so, a superimposed image is generated (step 507). Then, the image output unit 59 outputs the overlapped image to the display mechanism 95 (see FIG. 11) so that the overlapped window 32 including the overlapped image is displayed in the area designated by the moving operation on the normal window 31. (Step 508). At this time, the display mechanism 95 may erase the overlapping window 32 displayed in the movement source area.

  Furthermore, it is assumed that the type of operation transmitted to the superimposed image generation unit 56 is an enlargement / reduction operation of the overlapping window 32. In this case, the superimposed image generation unit 56 cuts out the image of the area specified by the enlargement / reduction operation from the basic mode image stored in the basic mode image storage unit 53, and performs image processing corresponding to the overlapping mode on this image. By doing so, a superimposed image is generated (step 509). Then, the image output unit 59 outputs the superimposed image to the display mechanism 95 (see FIG. 11) so that the superimposed window 32 including the superimposed image is displayed in the area designated by the enlargement / reduction operation on the normal window 31. (Step 510). At this time, the display mechanism 95 may erase the overlapping window 32 displayed in the area before enlargement / reduction.

  Thereafter, the process returns to step 503, and the operation receiving unit 58 receives the operation on the normal window 31 from the input device 96 (see FIG. 11) again. Although not shown in the figure, when the operation receiving unit 58 receives an operation for ending the display of the product data, the operation of this flowchart is also ended.

  As described above, in the second embodiment, the server 20 does not generate a superimposed image and the client 30 generates a superimposed image every time an operation is accepted, and is sometimes referred to as client-side processing.

  However, even in the second embodiment, when a tablet or the like having a low calculation specification (including battery life) is employed, there is a problem of processing cost.

  Therefore, it is conceivable to switch between the configuration of the first embodiment and the configuration of the second embodiment in accordance with the load amount for changing and displaying the superimposed image. For example, if the change of the superimposed image is mainly due to color conversion or enlargement / reduction, the load amount is small, so the configuration of the second embodiment is often effective. In addition, with regard to the processing over a plurality of pages, a part of the processing may be performed by the client 30, and if the memory amount and calculation performance of the client 30 do not satisfy the standard, a request for the remaining processing may be sent to the server 20. Further, since the load amount varies depending on the application function of the client 30 in the generation of the superimposed image, the configuration of the first embodiment and the configuration of the second embodiment may be switched accordingly. Furthermore, if the time from when the processing request is sent until the image is displayed is ignored, it is the server side processing that can be processed safely and completely. Alternatively, processing may be performed by the server 20.

  In other words, in this system, the server 20 generates two or more display mode images from the product data and sends them to the client 30, and the client 30 generates other display mode images according to the operation. The display system 10 includes means for displaying the images and means for switching the means for generating these images according to the display load amount.

  In the first embodiment, the example in which the components of the display system 10 are divided into the server 20 and the client 30 is shown, but the present invention is not limited to this. You may provide the component of the display system 10 in the display apparatus which is one computer.

[Second Embodiment]
(Overview)
The second embodiment is an embodiment in the case where it is given meaning that the display content up to that time is retained in the overlapping window 32 regardless of the image of the region where it overlaps.

  FIG. 8 is a diagram illustrating an example of a state when the overlapping window 32 is moved in the second embodiment. Also in this figure, the overlapping window 32 is moved to the cloud position. However, in the overlapping window 32, clouds and sky are not displayed, and the apple and the ground displayed in FIG. 1 are displayed in the display color as they are.

  In FIG. 8, the overlapping window 32 is moved, but the overlapping window 32 is not moved, and the overlapping window 32 is moved relative to the normal window 31 by turning pages in the normal window 31. It may be. This facilitates confirmation of an image based on the same data across a plurality of pages. At this time, a plurality of overlapping windows 32 may be displayed side by side.

  A display system that realizes such display will be described below.

(Display system configuration)
FIG. 9 is a block diagram showing a configuration example of the display system 10 in the present embodiment. In the display system 10, the server 20 as an example of a holding device includes a product data storage unit 61, a basic mode image generation unit 62, a basic mode image storage unit 63, a superposition mode image generation unit 64, and a superposition mode. An image storage unit 65, a superimposed image generation unit 66, and a superimposed image storage unit 67 are included. The client 30 as an example of a display device includes an operation receiving unit 68 and an image output unit 69.

  The product data storage unit 61, the basic mode image generation unit 62, the basic mode image storage unit 63, the superposition mode image generation unit 64, the superposition mode image storage unit 65, the operation reception unit 68, and the image output unit 69 are each a first one. Same as the product data storage unit 41, the basic mode image generation unit 42, the basic mode image storage unit 43, the superposition mode image generation unit 44, the superposition mode image storage unit 45, the operation reception unit 48 and the image output unit 49 in this embodiment. Therefore, explanation is omitted.

  When the operation accepting unit 68 accepts the creation operation of the overlap window 32, the overlapped image generation unit 66 cuts out an image of the area specified by the creation operation from the overlap mode image stored in the overlap mode image storage unit 65. As a result, a superimposed image is generated and stored in the superimposed image storage unit 67. When the operation accepting unit 68 accepts an operation for moving the overlapping window 32, the previously generated overlapping image is read from the overlapping image storage unit 67. Further, when the operation accepting unit 68 accepts an enlargement / reduction operation of the overlap window 32, the previously generated overlap image is read from the overlap image storage unit 67, and enlarged or reduced to generate a new overlap image. In the present embodiment, a superimposed image is used as an example of the second image.

  The superimposed image storage unit 67 stores the superimposed image generated by the superimposed image generation unit 66. In the present embodiment, a superimposed image storage unit 67 is provided as an example of a storage unit that stores the second image.

(Display system operation)
FIG. 10 is a flowchart showing an operation example of the display system 10 in the present embodiment. This operation is started when an instruction is given to display the designated page of the designated product data among the product data stored in the product data storage unit 61.

  When the operation starts, first, steps 601 to 603 are executed. However, step 601 to step 603 are the same as step 401 to step 403 in FIG.

  Thereafter, the operation accepting unit 68 accepts an operation on the normal window 31 from the input device 96 (see FIG. 11) (step 604). Then, the type of this operation is determined (step 605). Thereby, the determined type of operation is transmitted to the superimposed image generation unit 66.

  It is assumed that the type of operation transmitted to the superimposed image generation unit 66 is an operation for creating the overlapping window 32. In this case, the overlapping image generation unit 66 generates an overlapping image by cutting out the image of the area specified by the creation operation from the overlapping mode image stored in the overlapping mode image storage unit 65 (step 606). Further, the superimposed image is stored in the superimposed image storage unit 67 (step 607). Then, the image output unit 69 outputs the overlap image to the display mechanism 95 (see FIG. 11) so that the overlap window 32 including the overlap image is displayed in the area designated by the creation operation on the normal window 31. (Step 608).

  In addition, it is assumed that the type of operation transmitted to the superimposed image generation unit 66 is a movement operation of the overlapping window 32. In this case, the superimposed image generation unit 66 reads the superimposed image stored in the superimposed image storage unit 67 (step 609). Then, the image output unit 69 outputs the overlapped image to the display mechanism 95 (see FIG. 11) so that the overlapped window 32 including the overlapped image is displayed in the area designated by the moving operation on the normal window 31. (Step 610). At this time, the display mechanism 95 may erase the overlapping window 32 displayed in the movement source area.

  Furthermore, it is assumed that the type of operation transmitted to the superimposed image generation unit 66 is an enlargement / reduction operation of the overlapping window 32. In this case, the superimposed image generation unit 66 reads the superimposed image stored in the superimposed image storage unit 67 (step 611). Further, the superimposed image is enlarged or reduced at an enlargement / reduction ratio corresponding to the area designated by the enlargement / reduction operation (step 612). Then, the image output unit 69 displays the overlapped image display mechanism 95 (FIG. 11) so that the overlapped window 32 including the enlarged or reduced overlapped image is displayed in the area designated by the enlargement / reduction operation on the normal window 31. (See step 613). At this time, the display mechanism 95 may erase the overlapping window 32 displayed in the area before enlargement / reduction.

  Thereafter, the process returns to step 604, and the operation receiving unit 68 receives the operation on the normal window 31 again from the input device 96 (see FIG. 11). Although not shown in the figure, when the operation receiving unit 68 receives an operation for ending the display of the product data, the operation of this flowchart is also ended.

  In the second embodiment, the example in which the components of the display system 10 are divided into the server 20 and the client 30 is shown, but the present invention is not limited to this. You may provide the component of the display system 10 in the display apparatus which is one computer.

[Modification]
(Image defect warning display)
The display system 10 may display a warning on the overlap window 32 for the defect in the image detected by analyzing the overlap image. In other words, it may be configured to notify in which region of the image of the product data the image defect has occurred. Examples of such image defects include that CMYK data (or a mixture of RGB data of different standards) exists even though the product data image should be composed only of RGB data, For example, the gradation of the image is broken and the display color of the image of the product data is out of the color gamut. Since there are various known analysis methods for each of such problems, it is only necessary to detect the problem using this.

(Switch the display of the stacked window)
The display system 10 may switch the size of the overlapping window 32 from a size smaller than the normal window 31 to the same size as the normal window 31. Thereby, when the image in the normal window 31 and the image in the overlapping window 32 are compared, not only a partial difference in the product data but also a difference in the overall impression can be easily understood.

  The display system 10 may switch between displaying and hiding the overlapping window 32. As a result, the difference between the image in the normal window 31 and the image in the overlapping window 32 becomes clearer and can be easily confirmed.

(Processing based on multiple product data)
Up to now, the display system 10 displays an image of one product data in the basic mode and the overlap mode to compare the color states. However, the present invention is not limited to this. In principle, two product data for the same purpose, for example, partially retouched images may be compared to select a better one.

[Computer hardware configuration]
As described above, the present embodiment is realized by the display system 10 including the server 20 and the client 30 or a display device that is one computer corresponding to the function of the display system 10. Therefore, the hardware configuration of the computer 90 will be described assuming that the present embodiment is realized by the computer 90.

  FIG. 11 is a diagram illustrating a hardware configuration example of the computer 90. As shown in the figure, the computer 90 includes a CPU (Central Processing Unit) 91 as a calculation means, a main memory 92 as a storage means, and a magnetic disk device (HDD: Hard Disk Drive) 93. Here, the CPU 91 executes various types of software such as an OS (Operating System) and applications, and implements the above-described processing units.
