Is transferred to the server system 100 via. The material data PCD of a publication is stored in the hard disk 210 of the client device 200, and this material data PCD is transferred to the server system 100 when an on-demand publication is ordered. When the server system 100 executes the layout simulation and the bookbinding simulation and transfers the data (real simulation data RSD) to the client device 200,
The browser 202 displays the simulation result. A normal personal computer can be used as the client device 200.

On-demand printing / binding system 300
Is a device for creating a book according to the print / bookbinding data PD supplied from the server system 100. The completed book is delivered to the user. Note that in this system, as will be described later, the client device 200 and the server system 10 until the print / bookbinding data PD is completed.
0 only interactively exchanges various data and parameters. Therefore, there is an advantage that it is not necessary to send a bound book or the like to the user in advance, and only the finally bound book needs to be shipped to the user.

FIG. 2 is an explanatory diagram showing the overall flow of processing using this on-demand publishing system. The user uses the client device 200 to create the material data PCD
Are prepared (FIG. 2 (A)). In this embodiment, when the user accesses the server system 100 and orders printing / bookbinding, color calibration is first performed (FIG. 2).
(B)). This color calibration is a process for correcting the appearance of colors in the client device 200, and details thereof will be described later. Next, the user selects the material data P
When the CD is transferred to the server system 100, the layout execution unit 104 of the server system 100 executes the page layout simulation (FIG. 2 (C)). This page layout simulation is a process of arranging the material provided by the user according to the specified layout. At this time, the image is subjected to scaling, gradation conversion, color correction, sharpness processing, and the like. Also, regarding the characters, the font and size are adjusted. The simulation result is the client device 200.

When the contents of the book are confirmed, a bookbinding simulation is performed (FIG. 2 (D)). In this bookbinding simulation, the server system 100 creates bookbinding simulation data for displaying the three-dimensional bookbinding state of the publication. When this bookbinding simulation data is transferred to the client device 200, the three-dimensional bookbinding state of the publication is displayed by the browser 202 of the client device 200. In this way, when the user confirms the bookbinding state and the user issues a final delivery instruction,
The print / bookbinding data PD is transferred from the server system 100 to the on-demand printing / bookbinding system 300. The on-demand printing / bookbinding system 300 creates a book according to the printing / bookbinding data PD, and the completed book is delivered to the user.

B. Detailed procedure for on-demand publishing: Figure 3
6 is a flowchart showing a detailed procedure of on-demand publishing in the embodiment. The left side of FIG. 3 shows the process executed by the client device 200, and the right side shows the process executed by the server system 100. When the user first accesses the address for publishing a personal book provided by the server system 100 via the network NET (C100), the order screen is displayed on the server system 100.
From the client device 200 (S100),
The browser 202 of the client device 200 is displayed. FIG. 4 shows an example of the order screen. This order screen has fields for entering the user's name, address, delivery method, and the like. Although illustration is omitted, the order screen is prepared for a plurality of pages, and in addition to the personal information, the user can order contents (type of publication (book, book,
Set necessary items such as a booklet) and color / monochrome distinction).

When the input on the order screen is completed and the order contents including the personal information are transferred to the server system 100, the server system 100 stores (registers) the information in a database (not shown) ( S102).
When the order is placed in this manner, color calibration of the user environment is executed (C104, S104). This color calibration provides the server system 100 with color calibration information for calibrating the color reproducibility on the screen of the client apparatus 200, and the client apparatus 200.
The above is for ensuring natural color reproduction.

FIG. 5 is a flow chart showing the detailed procedure of color calibration. When the user presses the color calibration start button on the screen (not shown) (C2
00), the server system 100 transmits a Web page including an item image group for color calibration (S2).
00), the page is displayed by the client device 200 (C202). FIG. 6 shows an example of a web page including a plurality of item images. In this example,
In addition to the pictures of apples, pictures of bananas, sea, mountains, people, and sky are displayed. As the item image, an item that an ordinary person seems to clearly remember in color is prepared in advance. The user selects a plurality of images to be used as reference images for color calibration from these item images. At this time, it is preferable that an explanation is given to the user on the page so that the user selects an item image that the user can have if he / she remembers the color.

When a plurality of item images are selected, the server system 100 receives information indicating the selected item images, and whether or not the color space distribution of these images is sufficient for color calibration. Is analyzed (S2
02). In order to perform this processing, for example, the color space (for example, RGB color space) is divided into equal blocks, each block is given an ID, and the ID of the color space block of the color that each item image has It may be registered in the system 100 in advance. In this way, when the user selects some item images, it can be determined whether the selected item image group includes all the important color space blocks. For example, in the selected item image group, the color in the first color space block in which the R component is main, the color in the second color space block in which the G component is main, and the B component are main. It is possible to determine whether or not the selected item image group is sufficient for color calibration by including all of the colors in the third color space block.

When the selected item image group is insufficient for color calibration, the item image group having the missing color is transmitted to the client device 200 (S204, C206) and the item image is added to the user. A screen (not shown) prompting the user to make a selective selection is displayed on the client device 200.

In this way, when a plurality of item images having sufficient colors for color calibration are selected,
A screen for executing color calibration is displayed on the client device 200, and color calibration of the selected item image group is executed (C208). FIG. 7 shows an example of the color calibration execution screen. At the bottom of this screen, three selected item images (also referred to as “reference images”) are displayed in color. Moreover, an adjustment bar for adjusting the hue, the saturation, and the lightness is displayed on the item image. The user moves the scales of the adjustment bar so that the colors of the plurality of item images displayed at the bottom all match the memory color of the user. In addition to hue, saturation, and lightness, it is preferable to be able to set highlight points and shadow points, change contrast, and the like. In addition,
As the item image, it is preferable to use not only a color image but also a gray chart including a plurality of achromatic patches having different densities.

When the setting of the adjustment bar is completed, the corresponding color calibration parameter is transmitted from the client device 200 to the server system 100 (C210 in FIG. 5). The server system 100 uses the color calibration look-up table LU based on the color calibration parameters.
Generate T1. This lookup table LUT1
Is, for example, RGB data before color calibration and RG after color calibration.
Used to convert to B data.

By performing such color calibration, the color of an arbitrary image transferred from the server system 100 to the client device 200 is displayed so that a color as realistic as possible is displayed in the user's environment. Can be calibrated. The image that the user observes greatly depends on the environment of the user (particularly the spectral characteristic of the light source and the output characteristic of the display device). Therefore, by performing the color calibration suitable for the environment of each user, the color not depending on the user environment Reproduction can be realized. In particular, the item image (reference image) used for color calibration
Includes items (items) that many people are familiar with, and by using such item images, it is possible to set appropriate color calibration parameters according to the user environment. The screen of FIG. 7 corresponds to the color calibration parameter setting screen of the present invention.

When the color calibration is completed, a page for transmitting material data is displayed on the screen of the client device 200 (C106 in FIG. 3). Figure 8
The 1st Web page used for transmission of material data is shown. This Web page is a screen for selecting a paper layout template, and includes menus and fields relating to various items as described below. (1) Character direction (vertical writing / horizontal writing): (2) Document type (coterie magazine, album, book, etc.): (3) Paper size: (4) Layout type displayed on screen (all, for one image, (For 2 images, etc.): (5) Template menu: (6) Correspondence between page range and template number:

For each page of the printed matter, the user can select a layout template (one that does not include an image,
One or more). When such a template selection screen is used, a layout template can be selected for each page, so that the layout on the page is highly flexible and the user can easily create a preferred layout.

When the layout template is designated in this way, the material upload screen of FIG. 9 is displayed.
This page contains menus, windows, and fields for the following items: (1) Batch designation of texts and images / Page designation: (2) Window showing template contents of each page: (3) Designation of text file (text file): (4) Designation of image file:

When, for example, batch designation of sentences is selected in the menu of "lump designation of texts and images / page designation", only one text file is transferred, and the texts are automatically assigned in order from the first page. To be On the other hand, when the page designation of the text is selected, the text file is designated for each page. The same applies to images.

In the window showing the template contents of each page, only the template itself is displayed, and the result of actually laying out the user's material (text file or image file) is not displayed. The actual layout process is executed by the server system 100 after the setting of FIG. 9 is completed and the material data is transferred to the server system 100.

For an image, color correction (lightness, hue, saturation, contrast, etc.) may be required. Therefore, it is preferable to set the color correction information for the image using the same screen as that shown in FIG. At the time of setting the color correction information at this time, it is preferable to display the image in which the color of each image is calibrated using the lookup table LUT1 created by the color calibration.

In this way, when the material data (text or image) is transmitted (C106, S106 in FIG. 3) and the template information and color reproduction information are transmitted to the server system 100 (C108, S108), the server system 100 is sent.
Executes a layout simulation (S11
0).

FIG. 10 is a flow chart showing the detailed procedure of the layout simulation. In the layout simulation, first, the color conversion table LUT3 for color correction is created from the color correction information (color correction parameter) supplied from the client device 200 (S30).
0). Then, the color conversion table LUT3 and the color conversion table LUT1 for color calibration are combined to create the color conversion table LUTs for layout simulation (S302). Next, the layout process of the page is executed (S304). In this layout process, a layout simulation of each page is performed using a layout template and material data, and a color conversion table LUT for images is used.
Color correction is performed using s. The layout-completed data obtained by the layout simulation is transmitted to the client device 200. The laid out pages are displayed one by one on the screen of the client device 200. The screen of the laid-out page includes, for example, the image on the paper surface as shown in FIG.

The user confirms the layout displayed on the screen of the client device 200 page by page, and corrects the color of the image and the template if necessary (C1 in FIG. 3).
10, C108). When the color of the image (that is, the color correction information) or the template is corrected, the server system 100 executes the layout simulation again (S10).
8, S110, S112).

In this way, a satisfactory layout is completed,
When the user gives an instruction to complete the layout (C112), the server system 100 executes the bookbinding simulation (S114). FIG. 11 shows a bookbinding simulation (C1
12 is a flowchart showing the detailed procedure of S114). The client device 200 transmits the light source information and the bookbinding information to the server system 100 (C400, C4).
02). The light source information is information indicating the type of light source used in the environment of the user (that is, the light source used for illuminating the screen). The type of light source is selected from a plurality of options prepared in advance such as a daylight fluorescent lamp, a high color rendering fluorescent lamp, and an incandescent lamp. The binding information includes the paper type (paper quality) of the page, the cover type (color or material), the binding method, and the like. The light source information and the bookbinding information are set on a Web page (not shown) for inputting these information.

The server system 100 uses the light source information and the bookbinding information as well as the layout information, color calibration information, and color correction information set in the previous steps to generate a virtual book.

FIG. 12 is a flowchart showing the procedure for creating a virtual book. Here, first, the color conversion table LUT3 for color correction and the color conversion table LUT1 for color calibration are combined to create a color conversion table LUTt for bookbinding simulation. In addition, the color conversion table LUT2 relating to various light sources is also the above-mentioned two tables LUT1 and LU as necessary.
Synthesized with T3. Here, the color conversion table LUT2 regarding the light source is for reproducing the color appearance when the book is observed with a light source different from the light source of the current user environment (for example, outdoors). That is, the color conversion table LUT2 relating to the light source is a table showing the relationship between the color appearance under the light source of the user environment and the color appearance under the other type of light source. When using the color conversion table LUT2 relating to the light source, a plurality of types of color conversion tables LUTt are created. In the bookbinding simulation,
Using one or more color conversion tables LUTt as described above, a virtual book representing a three-dimensional bookbinding state of the book is generated. The color conversion table LUTt is mainly used for color correction of the color image in the material.

FIG. 13 shows a display example of a virtual book. FIG. 13A illustrates a state in which a hard cover book is closed. This book is a result of a simulation based on various shape data shown in the figure and the material of the cover. The material (texture) of the cover is similar to the actual cover. Various shape data are obtained from the result of the layout simulation.
The virtual book displays a three-dimensional bookbinding state,
The user can observe the bookbinding state from various angles by changing the viewpoint three-dimensionally. Further, it is possible to update and display the page of the bound publication.
Note that such virtual book data is, for example, VR
It can be realized by using ML or the like. further,
The user can observe the appearance of the book under the plurality of light sources by selecting one of the plurality of light sources as the observation condition of the book.

FIG. 13B shows a state in which a slightly thin booklet is opened. Although omitted here for convenience,
It is preferable that sentences and images actually laid out are pasted on the pages of this booklet. The user receives such virtual book data and confirms the bookbinding state (C406 and C408 in FIG. 11). At this time, the user can also observe the double-page spread while updating it. FIG. 14 shows a method of simulating the shape of the opening degree of a book. In this example, it is assumed that the left-side page can be approximated by an arc having a radius RL, and the right-side page can be approximated by an arc having a radius Rr1 at a portion close to the spine and a portion outside this can be a deformation Rr2. It is assumed that it can be approximated by an arc.

These radii RL, Rr1 and Rr2 are determined in accordance with the following rules, for example. (1) The ratio of the radii Rr1, RL is proportional to the number of left and right pages. Rr1 / RL = k1 [number of right side pages] / [number of left side pages] (2) The ratio of the radius Rr2 and the arc center position DL of the left side page is also proportional to the number of left and right pages. Rr2 / DL = k2 [number of right pages] / [number of left pages]

Note that k1 and k2 are coefficients, and different values are set depending on the paper quality of the page or cover, binding method, and the like.

Since the user can confirm the three-dimensional bookbinding state as shown in FIG. 13 on the client device 200, the bookbinding state can be confirmed in a state close to reality without actually holding the bookbinding sample. It is possible to In particular,
In this embodiment, since the book is displayed after color calibration is performed using the color calibration information (color calibration) that reflects the user's environment, it is possible to display a book close to an actual book. .

If the bookbinding state is unsatisfactory, the color correction information, the layout information, the bookbinding information (paper quality, etc.) are adjusted appropriately, and the layout simulation and the bookbinding simulation are executed again (C108 to C112 in FIG. 3). S
108-S114). At this time, when the items affecting the layout simulation are not changed (for example, only the material of the cover is changed), the layout simulation is not executed and only the bookbinding simulation is executed.

If the bookbinding state is satisfactory, the user presses a formal order button (not shown) provided on the bookbinding simulation result screen to instruct bookbinding (C114). Upon receiving this formal order (S116), the server system 100 transfers the print / bookbinding data to the on-demand printing / bookbinding system 300, and causes the book to be created. The book thus completed is delivered to the user. When creating print / bookbinding data, the table L used in the color calibration is used.
The color of the image is reproduced by using the table LUT3 for color correction without using the UT1 or the table LUT2 corresponding to the light source. By doing so, it is possible to create a printed matter that correctly reflects the color correction set by the user.

As described above, in the present embodiment, all the steps from the start of the order for making a book to the check of the bookbinding state are interactively performed via the network, so that the user can make a proof print or a bookbinding sample. Without actually shipping to
Book creation can be performed. Therefore, the user can easily order and obtain the book for himself.
