Creation of Simulation Image in User PC In this embodiment, a background image is displayed on the display unit of the user PC, simulation information including curtain attachment position information in the background image is received, and a curtain attachment scheduled object (window A curtain image to be attached to a wall including a wall), and the generated curtain image and the background image are combined to generate a curtain attachment simulation image in which the curtain is attached to the curtain attachment object in the background image, and the user PC Output to the display.

  FIG. 32 is a simulation screen in which a curtain is not attached (a background image of a room where the user desires to attach a curtain is displayed). Here, as the simulation information, the setting positions 360-1 and 360-2 of the product (curtain) in the background image 310 (displayed indoor image) displayed on the simulation screen may be designated by the cursor.

  And based on the setting positions 360-1 and 360-2 designated as simulation information, the horizontal width 350 and the height 352 of the curtain to be installed may be calculated and displayed. Obtain the number of screen pixels from the parameters of the PC being used, and obtain the layout location specification information (for example, the size of the room, the height to the window, the size of the window, etc.) The number of pixels per 1 cm is apportioned from the number of screen pixels obtained to obtain the number of pixels per 1 cm (unit pixel number parameter) in the background image displayed on the user's PC, and the setting positions 360-1 and 360 specified by the user -2 determines the number of pixels on the vertical and horizontal sides of the rectangle specified based on -2 (rectangles having the setting positions 360-1, 360-2 as diagonal vertices, hereinafter referred to as "specified rectangle") The horizontal width 350 and the height 352 of the curtain can be obtained based on the number of pixels on the vertical and horizontal sides of the rectangle and the unit pixel number parameter.

  In the present embodiment, in addition to the acquired PC screen pixels, the pixel number parameters (for example, the display size of the user screen and the number of pixels of the background image display area) (P1) and the acquired room size (P2) are used as parameters. Etc. may be held.

  FIG. 6 is a flowchart showing a flow of processing for displaying a simulation screen on which a background image is displayed from the generation of the background image.

  Indoor images (digital images) taken from the front of a digital camera, etc., including the window, the size information of the window, the location information of the window, the left and right walls adjacent to the wall, the ceiling, and the floor. A close-up image (digital image) obtained by close-up is acquired through the network in association with the user ID (step S110).

  A background image is generated based on the indoor image and the close-up image of the front, left and right walls, floor, and ceiling, and the generated background image is stored in the server in association with the user ID (step S120).

  The number of screen pixels is obtained from the parameters of the PC being used (step S130).

  The number of screen pixels may be read from the screen parameters of the PC used (user PC) when starting up the software of this embodiment (when starting up the program).

  Next, the acquired location position specifying information (for example, the room size, the height to the window, the window size, etc.) and the number of pixels per 1 cm are apportioned from the obtained screen pixel number and displayed on the user's PC. The number of pixels per 1 cm (unit pixel number parameter) in the background image is obtained (step S140).

  A simulation screen on which the background image is displayed is displayed on the display unit of the user PC (step S150). The background image may be displayed by replacing the window size information specified by the user and the window arrangement position specifying information (length, unit: centimeter) with the number of pixels on the user's screen.

  If there is no digital image, the room may be set on the simulation screen.

  The designation of curtain setting positions 360-1 and 360-2 is accepted from the simulation screen (step S160).

  Vertical and horizontal directions of rectangles specified based on the user-specified setting positions 360-1 and 360-2 (rectangles having the setting positions 360-1 and 360-2 as diagonal vertices, hereinafter referred to as “specified rectangles”) The number of pixels on the side is determined (step S170).

  The horizontal width 350 and the height 352 of the curtain are obtained based on the specified number of pixels on the vertical and horizontal sides of the rectangle and the unit pixel number parameter (step S180).

2-5. Curtain Image Creation Processing The curtain is divided into a race 410, a drape 420, and a balance 430 as shown in FIG. 33, and each product is displayed overlapping the background image 310.
(1) Representation method of width direction of lace and drape To generate a curtain image with a crease as shown in FIG. 34 (A) for the specified product (lace and drape) width, the following Process.

  For example, as shown in FIG. 34B, a partial image having four folds of a predetermined fold width is created for all fabrics (materials), and the created partial image data is stored in association with the fabric identification ID. . When a cloth or fabric is designated as the simulation information, a partial image corresponding to four folds held in association with the cloth identification ID corresponding to the designated cloth or cloth is read out. Also, based on the horizontal width of the curtain size (in this case, the length, for example, xcm) and the planned horizontal width of the partial basic image for four folds (in this case, the length, for example, BK2 cm), the repetitive size (for example, x / BK2 rounded up number, N). Then, the partial basic image is repeatedly arranged N times from the left side. For example, if the width x is 220 cm and the planned width size BK2 is 40 cm, the number of repetitions N is 6. However, since the repetition is 5 times 40 cm and the last is 20 cm, if six partial basic images are connected, the actual curtain size becomes larger.

  Therefore, in the present embodiment, as shown in FIG. 35, the partial image is shifted from the left end in the width direction and arranged five times (n = 1 to 5), and the last one (n = 6) is the partial basic image. May be arranged from the right end.

  A specific example of generation of a creased curtain image will be described. In FIG. 36, the coordinates of the set position 360-1 are A (X2, Y2), the coordinates of the set position 360-2 are B (X3, Y3), and the coordinates of the vertex C of the rectangle having A and B as the vertices on the diagonal line. (X3, Y2). Coordinate values are given by pixel positions, and X2 = 211, Y2 = 234, X3 = 819, and Y3 = 680. X3 and Y2 of C point are obtained from A and B. Here, X3−X2 = 819−211 = 608 (the number of horizontal pixels between ACs on the screen of the user PC). When this value is converted into cm units using the unit pixel number parameter, it is assumed that 242 cm (variable h1) is obtained. When the variable h1 is divided by the pleat width variable (h2), for example, 242 / 11.5 = 21.043 is rounded off to 21 (variable h3). When the curtain (lace or drape) style is double-opened, an even number may be used as the number of folds (variable h3 = h3 + 1). Note that the variable h2 is a width of one fold, but if another fold width is desired, the fold width can be changed to another value.

  An example of how to obtain the curtain width when generating a curtain image with the calculated number of folds will be specifically described. Assuming that X3−X2 = variable h4, when X2 is 211 and X3 is 819, h4 = 608. Further, assuming that variable h5 = variable h4 / variable h3 (the number of folds), h5 = 608/22 = 27.63.

  A partial image corresponding to the selected fabric is selected from the partial images for each fabric registered in the database in advance. The partial image is an image generated with 4 folds as one unit as shown in FIG. 34 (B), for example. Note that the image shown in FIG. 34B may be generated by synthesizing partial images in the height direction, as will be described later.

  Here, a case where a partial image having 4 folds as one unit is described as an example, but a partial image having 2 folds or 1 fold as one unit may be used. When a partial image having 4 folds as one unit is used, if the width of the 4 folds of the partial image is a variable h6, the variable h6 = variable h5 × 4. Further, if the number of repeated arrangements in the width direction when using a partial image by cloth in units of 4 folds is N, N (carrying integer) = variable h3 / 4. The process of arranging the positions of the partial images for each cloth at a predetermined interval in the width direction is performed until n is the number N of repeated arrangements, where n is a repetitive arrangement variable.

  Here, the horizontal width of the partial image in units of 4 folds as shown in FIG. 34B is a variable h6, and the initial arrangement position is, for example, as shown in FIG. It is assumed that the screen left corner P1 (x1, y1) is arranged, and in the case of n = 2, the four-fold unit partial image is arranged at the screen left corner P1 (x2, y1). The partial image in the case of n = 1 is arranged between x1, x1 + variable h6 in the width direction. The partial image in the case of n = 2 may be arranged to overlap the partial image in the case of n = 1 by 1 pixel (pixel). That is, the partial image may be arranged from the position one pixel before x2 = (x1 + variable h6). For n = 2 to 5, processing is performed from one pixel before (overlapping one pixel), and in the last arrangement (n = N (n = 6 in FIG. 40)), the right (X3 of C in FIG. 38) And the right edge of the partial image (510-R in FIG. 34B) are aligned and arranged.

  A partial image having 4 folds as one unit (referred to as a 4 fold partial image) and a partial image having 3 folds as one unit (referred to as a 3 fold partial image) are prepared, and both ends of the curtain image (n = in FIG. 35). 1 and n = 6) may be arranged with 3 fold partial images, and 4 fold partial images may be arranged in the inner portion (n = 2 to n = 5 in FIG. 35).

  FIG. 52 shows an example of partial images having different vertical lengths.

  Reference numerals 960 to 966 indicate a plurality of partial images having different vertical lengths with a given unit length (for example, a length corresponding to 4 folds) with respect to the same fabric. 960 is a partial image corresponding to a length of 80, 961 is a partial image corresponding to a length of 110, 962 is a partial image corresponding to a length of 140, and 963 is a partial image corresponding to a length of 170. 964 is a partial image corresponding to a height of 200, 965 is a partial image corresponding to 200, and 966 is a partial image corresponding to 230.

By repeatedly arranging the partial images 960 in the horizontal direction, an image of a curtain having a height of 80 can be generated. By repeatedly arranging the partial images 961 in the horizontal direction, an image of a curtain having a height of 110 can be generated. By repeatedly arranging the partial images 962 in the horizontal direction, an image of a curtain having a height of 140 can be generated. By repeatedly arranging the partial images 963 in the horizontal direction, an image of a curtain having a height of 170 can be generated. By repeatedly arranging the partial images 964 in the horizontal direction, an image of a curtain having a height of 200 can be generated. By repeatedly arranging the partial images 965 in the horizontal direction, an image of a curtain having a height of 230 can be generated. By repeatedly arranging the partial images 966 in the horizontal direction, an image of a curtain having a height of 260 can be generated.
(2) Expression Method for Length of Lace or Drape FIG. 37 is a diagram for explaining a technique for expressing the length of a race or drape. As shown in the figure, a partial image having a predetermined length (for example, 40 cm) from the top of the header with a width of every 4 folds is set to a partial image 550 and a predetermined length (for example, 40 cm, the length of the partial A image) A partial image (which may be the same or different) may be a B partial image 550, and a partial image following the B partial image 560 may be a C partial image 570.

  Select one of the A partial image 550, the B partial image 560, and the C partial image 570 from the database according to the specified header and the specified curtain height, and arrange them in the height direction to generate, for example, a partial image for four folds. . By doing so, it is possible to more realistically reproduce the pattern pitch width of the fabric pattern (print, jacquard, etc.).

  For example, an image arranged in the height direction according to the curtain length (distance P1 (Y2-Y3) between BC in FIG. 36) may be arranged as shown in FIG. FIG. 38A shows that the A partial image is arranged once and a partial image satisfying the curtain length is generated. FIG. 38B indicates that a partial image satisfying the curtain height is generated by arranging the A partial image once and the B partial image once in the height direction. FIG. 38C indicates that the partial image satisfying the curtain length is generated by arranging the A partial image once, the B partial image once, and the C partial image once in the height direction. FIG. 38D shows that a partial image that satisfies the curtain length is generated by arranging the A partial image once, the B partial image once, and the C partial image twice. FIG. 38E indicates that a partial image satisfying the curtain height is generated by connecting the A partial image once, the B partial image once, and the C partial image three times in the length direction.

  For example, the case where the height is 180 cm corresponds to the case of FIG. 38E, and the partial image having a length of 40 cm is arranged five times in the length direction, so the length in the length direction is 200 cm. Since the required height this time is 180 cm, it can be realized by reducing the length of 200 cm by 10% in the length direction.

  39A and 39B are diagrams for explaining the arrangement method of the partial images in the height direction.

A reduction of 10% may be realized by overlapping each partial image in the height direction. For example, in FIG. 36, if Y2 is 234 and Y3 is 680 (in FIG. 36, the pixel value is the origin (0, 0) at the upper left end O of the screen), a partial image is pasted from Y axis 234 to 680 in case of,
Number of pixels in the length direction = 680−234 = 446
Length per partial image = Number of pixels in the length direction / Number of partial image placements
= 446/5 = 89.2
It becomes. In this case, since the decimal point has little meaning, it is set to 89 or 90. The first partial image 610 ′ (A) is arranged in y (1) S to y (1) E, and the second partial image 620 ′ (B) is arranged in y (2) S to y (2) E. The third partial image 630 ′ (C) is arranged in y (3) S to y (3) E, and the fourth partial image 640 ′ (C) is converted to y (4) S to y (4) E. The last partial image 650 ′ (C) is arranged in y (5) S to y (5) E. In this way, the partial images overlap and are arranged in the shaded portion, thereby realizing a reduction of 10%. Here, y (1) to y (6) are as follows.

y (1) = 234,
y (2) = y (1) + 89 = 323
y (3) = y (2) + 89 = 412
y (4) = y (3) + 89 = 501
y (5) = y (4) + 89 = 590
y (6) = y (6) + 90 = 680
By subdividing in this way, the amount of image data (partial image data) stored in the server can be reduced, and the amount of data exchanged between the server and the client PC can be reduced, thereby shortening the image processing time. I can do it.
(3) Partial Image Creation Method FIGS. 40A to 40C are diagrams for explaining a partial image creation method. First, a three-dimensional model of a 4-fold curtain part as shown in FIG. Here, the vertical and horizontal sizes may be assumed to be 11.5 cm between the pleats, and the settings are 92 pixels vertically, 360 pixels vertically, and 46 × 180 cm.

  Next, as shown in FIG. 40B, a material (such as a fabric texture) 620 is mapped to a four-fold three-dimensional model 610 by a rendering technique.

Here, the sizes of the three-dimensional model 610 and the material 620 are matched.
The taken-in dough assumes a 46cm square. Since a double fold design requires double material, a texture having a double length K2 (K1 × 2) is prepared in the horizontal direction. In the vertical direction, the material 620 is pasted four times at different positions.

  Then, the two-dimensional image on which the material is mapped is stored as a partial image with transparent background. For example, as shown in FIG. 40C, a 3-fold partial image and a 4-fold partial image may be prepared.

  41A to 41E are examples of curtain image creation. 630 in FIG. 41A is a curtain image in a closed state in which partial images are combined vertically and horizontally to have a predetermined width and height. Reference numeral 640 in FIG. 41B denotes an open curtain image 640 generated by reducing the closed curtain image 630 in the horizontal direction. Reference numerals 650-1 and 650-2 in FIG. 41C are an upper partial image 650-1 and a lower partial image 650-1 that are generated by dividing the curtain image 640 in an open state vertically. 660-1 and 660-2 in FIG. 41D are images obtained by modifying the upper partial image 650-1 and the lower partial image 650-1 that are divided in order to generate an image in which the curtain is narrowed down in the middle. It is. In FIG. 41E, reference numeral 670 denotes a curtain image in a state of being narrowed down in the middle generated by combining the deformed upper partial image 660-1 and lower partial image 660-1.

  Each image in FIGS. 41A to 41E may be created in advance and stored in a server or the like as image data, or may be generated in real time during simulation.

  For example, when the curtain image in the closed state shown in FIG. 41A is generated, partial images are prepared in advance, and the processing of arranging the partial images by connecting them vertically and horizontally can be performed in real time. . In this way, the amount of data to be stored can be reduced, and the processing time (time required for data transmission, etc.) can be shortened.

  For example, when the curtain image in the open state shown in FIG. 41B is generated, a partial image in the open state may be generated and stored in advance.

For example, when generating the curtain image 670 in a state of being narrowed down in the middle of FIG. 41E, the upper and lower partial images 660-1 and 660-1 modified in advance in FIG. 41D are generated. You can also memorize it. In this way, since the processing to be performed in real time is only the arrangement of the partial images, the processing load can be reduced and the processing time can be shortened.
(4) Method of Expressing Top Decoration (Balance) As shown in FIGS. 22 to 29, on the simulation screen of the present embodiment, the state of the curtain with the top decoration to which the top decoration (balance) is added for a given curtain Can be simulated.

  As the upper decoration (balance) information, a swag overlapping pattern (array sample) or information 450 of each swag (the length of the swag 452 or the number of pleats of the swag 454) may be specified.

  Reference numeral 400 in FIG. 23 denotes a designation field for a swag overlap pattern (array sample). For example, array sample display images 410 to 418 in which overlap patterns (array samples) are schematically displayed in the simulation information designation field on the simulation screen may be displayed, and the swagger overlap pattern may be designated.

  23. When the array sample image 418 is selected as the simulation image of the simulation screen of FIG. 23 (a style in which three swags overlap each other and a middle swag overlaps the left and right swags), the upper curtain image Is displayed.

  The swag overlap order may be stored in advance in association with the swag overlap pattern (array sample).

  42A to 42C are diagrams for explaining the relationship between the swag overlap pattern (array sample) and the swag overlap order.

  Each of them has three swags (right swag SW1, central swag SW2, left swag SW3), and each swag is overlapped differently.

  In FIG. 42A, in the case of a swag overlap pattern (array sample) 414, the swag overlap order is SW3 → SW2 → SW1 (SW3 is at the bottom) as shown at 415. . In FIG. 42B, when the swag overlap pattern (array sample) 416 is used, the swag overlap order is SW1 → SW2 → SW3 (SW1 is at the bottom) as indicated by 417. . FIG. 42C shows a swag overlap pattern (array sample) 418, the swag overlap order is SW1 → SW3 → SW2 (SW2 should be at the top as shown by 419. SW1. And the order of SW2 may be reversed.

  For the stacking order, the stacking order information of the swags held in association with the overlapping pattern (array sample) of the selected swags is acquired, and the layers are stacked according to the acquired stacking order information of the swags.

  FIGS. 43A to 43C are diagrams for explaining a method of generating a top curtain image.

  FIG. 43A is an example of the partial image of the top decoration. Here, a case where an image of each swag constituting the upper decoration is held as a partial image of the upper decoration will be described as an example. The image of each swag may be prepared for each number of pleats of the swag and the kind of the fabric.

  For each swag image, for example, a three-dimensional model corresponding to one swag (a three-dimensional model may be prepared for each number of pleats of the swag) is generated, and a viewpoint position is set in front of the three-dimensional model, A two-dimensional swag image may be generated by performing perspective projection conversion and mapping the texture of the material corresponding to the fabric.

  Based on the simulation information specified on the simulation screen (for example, the type of curtain cloth), the swag image corresponding to the specified curtain cloth or decoration type is selected.

And based on the specified curtain mounting position information, based on the calculated curtain size information width and the overlapping pattern (array sample) of the selected swag,
The vertical and horizontal enlargement / reduction of the swag image 450 is performed, and the upper decoration curtain image is generated by arranging according to the overlapping order information.

For example, in the case of a swag overlapping pattern (array sample) 418 as shown in FIG. 43 (C), as shown in FIGS. 43 (B) and (C), first, SW1 and SW3 swag images are arranged, The SW2 swag image may be overlaid from above.
(5) Representation method of various decorations When the selected decorations (frills and fringes) are matched with lace, drape, and balance, the following processing may be performed.

  FIG. 44 is a diagram for explaining a method of matching ornaments (decorations such as lace and fringe) with laces and drapes.

  470 is an undecorated curtain image with no decoration (curtain image with only lace and drape without frills and fringes), and 480 is a decorative image with only the decorative portion (the curtain body part such as lace and drape is masked) 490 is a decorative curtain image obtained by combining the non-decorative curtain image 470 and the decorative partial image 480.

  A decorative partial image 480 having the same total number of pixels as the non-decorative curtain image 470 (the same number of vertical and horizontal pixels) is prepared in advance.

  For example, when decorating a lace or drape, set the decoration attachment position to 3 types (bottom side, inside and bottom side, both sides and bottom side), and specify the desired attachment position as simulation information. Select the selected image. For example, decorative images corresponding to each of the three types may be prepared.

  The decorative image 480 may be an image having the same number of pixels as the non-decorative curtain image 470 and a decorative part created by a two-dimensional image creation technique.

A decorative curtain image 490 can be generated by combining the decorative partial image 480 and the non-decorative curtain image 470 corresponding to the selected decorative attachment position. In FIG. 44, the case where the decoration image of the completed curtain is prepared is described as an example, but a decoration image corresponding to the partial image may be prepared. For example, a decoration partial image for each type of decoration arranged over the partial image is stored, a decoration image is selected based on the decoration information specified as simulation information, and the selected decoration image and the partial image are combined. A curtain image may be generated.
(6) Calculation Method of Fabric Usage Amount FIGS. 45 to 49 are diagrams for explaining a calculation method of fabric used for a curtain.

  As shown in FIG. 45, the length of the cloth 700 in the width direction 712 is called the cloth width, and the length in the scale direction is called the main scale. The fabric 700 has a predetermined fabric width (which is determined by the fabric) and can take an arbitrary length in the scale direction.

  FIGS. 46A to 46C are diagrams for explaining an example of a method for joining curtain-sized fabrics. P1 and P2 of the curtain 750 in FIG. 46A are the width and height of the curtain size information set by the user. Since curtains are creased in the width direction, an extra amount of crease is required in the width direction relative to the width of the curtain. For example, when making a double-fold fold, the length of K2 = P2 × 2 + α (the amount of folding, about 10 cm in total on the left and right) is required with respect to the curtain width P2. Further, when the curtain length is P1, the length of K1 = P1 + β (the amount of folding up and down, about 30 in total) is required with respect to the curtain length P1.

  Here, a case where the width of the fabric (710 in FIG. 45) is 150 cm and the curtain length P1 is 180 cm will be described as an example. Since the curtain does not join the cloth in the length direction, in such a case, for example, as shown in FIG. 46 (C), the cloth 700 is cut in the direction of a1, a2, a3,. As shown in B), the cut fabrics a1, a2, a3,... Are aligned and joined in the curtain width direction.

  47A to 47C are diagrams for explaining another example of how to join curtain-sized fabrics. Here, the case where the width of the fabric (710 in FIG. 45) is 280 cm and the curtain length P1 is 180 cm will be described as an example. In such a case, since K1 is about 210 cm, the length of the curtain can be taken in the width direction of the fabric. For example, as shown in FIG. By taking the length K2, the curtain can be created because the fabric is not joined to the width clause of the curtain.

  FIG. 49 is a diagram for describing the dough information included in the present embodiment. The fabric information 800 of the present embodiment is stored in the fabric information storage unit. When the present embodiment is implemented stand-alone, the fabric information storage unit may be provided in the user computer. If this embodiment is implemented as a system in which a server and a client PC are connected via a network, the server database functions as a fabric information storage unit, and the fabric information is downloaded to the client PC as necessary. It may be used.

  The fabric information 800 includes a fabric width 820, a vertical repeat 830, a horizontal repeat 840, a unit price (for example, a fabric unit price per unit length) 860, and the like, which may be stored in association with the fabric identification ID.

  The vertical repeat 830 is a repeated width of the pattern in the fabric width direction 720, and the horizontal repeat 840 is a repeated width of the pattern in the fabric width direction 712.

  48A to 48E are diagrams for explaining the vertical repeat and the horizontal repeat. FIG. 48A shows an example of a fabric having a fabric width 710 of 150 cm, a vertical repeat TR30CM, and a vertical repeat TR45 cm (see 850 in FIG. 49). The vertical repeat TR30CM means that the same pattern is repeatedly arranged in 30 cm units in the scale direction 712. The horizontal repeat YR45CM means that the same pattern is repeatedly arranged in units of 30 cm in the width direction 720.

  FIG. 48B is an example of a fabric having a fabric width 710 of 150 cm, a vertical repeat TR0, and a vertical repeat TR45 cm (see 852 in FIG. 49). The vertical repeat TR0 means that pattern matching in the scale direction 720 is not necessary.

  FIG. 48C shows an example of a fabric having a fabric width 710 of 150 cm, a vertical repeat TR45 cm, and a vertical repeat TR0 (see 854 in FIG. 49). The horizontal repeat YR0 means that pattern matching in the width direction 712 is not necessary.

  FIG. 48 (D) shows an example of a fabric having a fabric width 710 of 150 cm, a vertical repeat TR0, and a vertical repeat TR0 (see 856 in FIG. 49). The vertical repeat TR0 and the horizontal repeat YR0 mean fabrics that do not require pattern matching in both the scale direction 720 and the width direction 712 (for example, plain).

  FIG. 48E is an example of a fabric having a fabric width 710 of 300 cm, a vertical repeat TR30 cm, and a vertical repeat TR30 cm (see 859 in FIG. 47). Since this fabric has a fabric width 712 of 300 cm, the length of the curtain in the width direction of the fabric can be taken as shown in FIGS. 47 (B) and 47 (C).

  In the present embodiment, the fabric usage amount of the curtain corresponding to the simulation image generated based on the simulation information is calculated, and the curtain fee is calculated and presented based on the fabric usage amount.

  FIG. 50 is a flowchart of a process for calculating the curtain fee, and FIG. 51 is a diagram showing an example of calculating the used fabric amount.

A charge calculation request is received on the simulation screen (step S210).
The curtain size (curtain width and height), the number of folds, the fold magnification, and the fabric identification ID of the curtain image on the simulation screen are received (step S220). For the curtain size information and the number of folds, information calculated based on the curtain setting position may be used.

  Fabric information such as fabric width information, vertical repeat information, horizontal repeat information and unit price information stored in association with the received fabric identification ID is read from the fabric information storage unit (step S230).

  Based on the curtain length information, the length (K1) of the fabric required in the length direction is obtained (step S240). For example, when vertical repeat is not considered (in the case where there is no vertical repeat, etc.), as shown in FIG. 51, when the number of folds is 20, the curtain length is 180 cm (912), and the fabric width is 150 cm, the length is as shown by 910. The fabric length (K1) required in the direction is 210 cm. When vertical repeat is considered, 150/15 = 14 when the vertical repeat is 15 cm, and the vertical pattern matches without correction. If the vertical repeat is 18 cm, 210/18 = 11.666, so the repeat count is increased to 12 times, and 12 × 18 = 216 is the necessary scale per width. Therefore, when the necessary fabric width (K3) is 4, the total scale is 216 × 4 = 864.

  Based on at least one of the fabric width information 916 and the length (K1) of the fabric required in the length direction, it is determined whether or not the curtain length can be taken with the fabric width (step S250). For example, if the fabric width information and the length of the fabric required in the length direction of the curtain (K1) are compared, if the fabric width information and the length of the fabric required in the length direction <fabric width, the length of the curtain is determined by the fabric width. It may be determined that the curtain can be removed, and if the fabric width is a predetermined size or more (for example, 280 cm or more), it may be determined that the curtain width can be taken with the fabric width.

  It is determined whether or not the curtain length can be taken with one fabric width (step S260). If it is determined that the curtain length can be taken, the fabric required in the curtain width direction based on the curtain width or the number of folds and the widthwise folding width. Is obtained (K2). When the curtain width and the fold magnification are known, K2 = curtain width × fold fold magnification + width direction folding width may be used. If the number of folds 918 and the length of one fold 920 are known, K2 = the number of folds × the length of one fold + the width direction folding width. Then, as shown at 940, based on the length (K2) of the required fabric in the width direction of the curtain, the necessary size of the required fabric is calculated, and the usage amount of the curtain fabric is obtained (step S270).

  In addition, when the length of the curtain can be obtained with one width of the cloth, it is not necessary to join the cloths, so that it is not necessary to consider vertical repeat and horizontal repeat.

  If it is determined that the length of the curtain cannot be obtained with the width of one cloth, the length (K2) of the cloth necessary in the width direction of the curtain is obtained based on the width of the curtain or the number of folds and the folded width in the width direction. The required fabric width (K3) is obtained based on the required fabric length (K2) and the fabric width in the curtain width direction.

  When the length of the curtain cannot be obtained with the width of one cloth, it is necessary to join the cloths as shown in FIGS. 46 (B) and 46 (C). Therefore, if the fabric has horizontal repeats, consider the horizontal repeat value (considering the length that can actually be used in the width direction of 1 width (K4)) and the number of sheets to be joined (required fabric width K3). Ask.

  If the horizontal repeat is 15cm, the horizontal repeat comes into the fabric with a fabric width of 150cm without waste, so no extra cloth is required to correct the pattern matching. Therefore, for example, as shown at 850, the total width / fabric width = 470/150 = 3.1333 (variable A), and the variable A is incremented so that the necessary fabric width (K3) = 4.

  Further, for example, if the horizontal repeat is 55 cm, only two horizontal repeats can be included in the fabric width of 150 cm, so the length (K4) that can actually be used in the width direction of one width is 110 cm. Accordingly, the total width / the actual usable length (K4) = 470/110 = 4.2727 (variable A), and the variable A is raised to obtain the necessary fabric width (K3) = 5.

  Further, the length (K1) of the fabric required in the curtain length direction is obtained. Here, when the fabric has a vertical repeat, the length (K1) of the fabric required in the curtain length direction per width is determined in consideration of the value of the vertical repeat. Based on the length (K1) of the fabric required in the curtain length direction per width and the required fabric width (K3), the scale is calculated to determine the amount of curtain fabric used (step S280).

  For example, when the vertical repeat is 15 cm, 150/15 = 14, and the vertical patterns match without correction. If the vertical repeat is 18 cm, 210/18 = 11.666, so the repeat count is increased to 12 times, and 12 × 18 = 216 is the necessary scale per width. Therefore, when the necessary fabric width (K3) is 4, the total scale is 216 × 4 = 864.

  Then, the curtain fee is calculated based on the usage amount of the curtain fabric and the unit price of the fabric (step S290).
