[0001]
[Industrial application fields]
The present invention relates to a method and an apparatus for creating an image of a plurality of rectangular blocks having the same width but different lengths, and an image in which an appropriate pattern is pasted on the rectangular blocks.
[0002]
[Prior art]
Conventionally, as shown in FIG. 11, an image in which an appropriate pattern such as a wood grain pattern is cut out as a rectangular block and pasted in a tile shape is known, and such an image is used for wallpaper, flooring, etc. Widely used for building materials. In addition, although the case where a grain pattern is used is shown in FIG. 11, the pattern cut out to a rectangular block is not limited to the grain pattern, and a stone pattern or any other pattern can be used. Also, the rectangular blocks in FIG. 11 have the same horizontal block width, and the vertical block lengths in FIG. 11 are not all the same, and are within a predetermined length range. It is normal.
[0003]
When an image as shown in FIG. 11 is created, conventionally, an operator actually cuts and arranges a rectangular block from a printed material with an appropriate pattern by hand, or creates such an image on a computer. When creating an image, an image with an appropriate pattern for cutting out the rectangular block is displayed on the screen, the area to be cut out is specified, and the position of the cut out rectangular block is further determined. It was necessary to specify by inputting the coordinate value.
[0004]
However, when such an image is used as a building material such as flooring or wallpaper, the size of the image to be created is often a large image of about 1 m × 1 m. However, the correction work was very troublesome.
[0005]
Therefore, the applicant of the present application automatically creates a rectangular block and pastes a pattern in Japanese Patent Application No. 10-240672 in order to reduce the burden on the operator when creating an image as shown in FIG. A method and apparatus are proposed. As a result, the operator simply sets the size (width, height) of the created image, the fixed-length block width, the maximum value and the minimum value of the block length, which are variable lengths, as shown in FIG. Patterns can be generated automatically. In this apparatus, each block is managed by a block number (1 to 9 in the example of FIG. 12) by the upper left coordinates of the block, the block width (horizontal direction in the drawing), and the block length (vertical direction in the drawing). .
[0006]
An actual building material product is created by creating an image in which a plurality of block patterns composed of a plurality of blocks as shown in FIG. 12A are arranged vertically and horizontally, and printing the image. At this time, an image in which two block patterns of FIG. 12A are arranged vertically is as shown in FIG. 12B, but the joint of each block pattern becomes conspicuous as shown by the left and right arrows. There is a problem.
[0007]
[Problems to be solved by the invention]

[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing an embodiment of an image creating apparatus according to the present invention, in which 1 is a specification setting device, 2 is a pasted image input device, 3 is a block shape generating device, 4 is a pasted pattern extracting device, Reference numeral 5 denotes a block shape correcting device, 6 denotes an image composition device, 7 denotes a display device, 8 denotes a storage device, and 9 denotes an input device.
[0013]
First, the outline of each apparatus shown in FIG. 1 will be described.
The specification setting device 1 is for setting various specifications relating to an image to be created. Here, at least the size of an image to be created (hereinafter referred to as a created image), the width of a rectangular block (hereinafter simply referred to as a block), and the maximum and minimum values of the block length are set.
[0014]
The pasted image input device 2 is for inputting an image as a basis of a picture to be pasted on each block generated by the block shape generating device 3. Note that only one image or a plurality of images may be input.
[0015]
The block shape generation device 3 automatically generates a block based on the maximum value and the minimum value of the created image size, block width, and block length set by the specification setting device 1.
[0016]
The pasted pattern extraction device 4 is for automatically extracting the pattern pasted to each block generated by the block shape generation device 3 from the image input from the pasted image input device 2. In addition, when an instruction to change the paste pattern of a certain block is given, the paste pattern extracting device 4 automatically adds a new paste pattern from the input paste image to the block. The extraction process is also performed.
[0017]
The block shape correcting device 5 is used when correcting the length of the block generated by the block shape generating device 3.
[0018]
The image composition device 6 corresponds to the block generated by the block shape generation device 3, the pattern extracted by the pasted pattern extraction device 4, or the block corrected by the block shape correction device 5, and the corrected block. Then, the pasted picture extracted by the pasted picture extracting device 4 is synthesized.
[0019]
The display device 7 pastes an image of a block generated by the block shape generation device 3, an image of a block corrected by the block shape correction device 5, and a pattern extracted with respect to the block synthesized by the image synthesis device 6. This is for displaying a rare image or the like, and is composed of known display means such as a color CRT.
[0020]
The storage device 8 stores an image to be pasted in association with each block of the determined block image, and is configured by a large-capacity storage unit such as a hard disk device.
[0021]
The input device 9 is for performing input or activation with respect to each of the above-described devices, and includes a keyboard, a mouse, and the like.
Note that the image creating apparatus as described above can be configured by a personal computer or the like.
[0022]
Next, the processing operation of the image creating apparatus shown in FIG. 1 will be described together with the image creating method. First, a specification is set by the input device 9 using the specification setting device 1 and a paste image is input from the paste image input device 2. When an image of a desired pattern is stored in a storage medium such as a floppy disk, the pasted image can be input by setting the storage medium in the pasted image input device 2 and capturing the desired image. Can be read and input with a color scanner, and if the desired image data is in the database, the image data can be imported by the pasted image input device 2 via the network. good. Here, although one image is input as a pasted image, a plurality of image data may be input.
[0023]
In the specification setting device 1, the maximum value and the minimum value of the created image size, block width, and block length are input as parameters. Here, as the created image size, the horizontal value (X direction) is set to width, the vertical direction (Y direction) is set to height, the block width is set to bw, the maximum block length is set to bhmax, and the minimum value is set to Assume that bhmin is set. Here, it is assumed that the width direction of the block is the horizontal direction (X direction) of the created image.
[0024]
When the specification setting and the input of the pasted image are completed as described above, the operator activates the block shape generation device 3 by the input device 9. Then, the block shape generator 3 generates a block based on the specification set by the specification setting device 1. The process will be described with reference to the flowchart shown in FIG.
[0025]
The block shape generation device 3 first determines whether or not the parameters set by the specification setting device 1 are appropriate (step S1). The parameter determination in step S1 is determined according to the flowchart of FIG.
[0026]
First, the maximum number nmax and the minimum number nmin of the number of blocks that can be generated in one column are obtained by the following equations (step S21).
nmax = height / bhmin, nmin = height / bhmax
Since nmax and nmin must both be integers, in the above formula, the decimal part is rounded down.
[0027]
Next, it is determined whether nmax = nmin is satisfied (step S22). If it is determined to be no here, the parameter is determined to be appropriate. Conversely, if it is determined yes, it is determined whether nmin × bhmax = height holds (step S23). If “yes” is determined here, the parameter is determined to be appropriate. Conversely, if it is determined to be no, it is determined whether nmax × bhmin = height holds (step S24). If “yes” is determined here, the parameter is determined to be appropriate. Conversely, if it is determined to be no, the parameter is determined to be inappropriate.
The following is a description of the theory on which the processing from step S22 to step S24 is performed. In the block shape generation device 3, processing is performed so as to fit exactly within the height height of the image within the range of the set maximum and minimum block lengths, but the maximum number nmax and the minimum number of blocks If nmin is the same, the number is not flexible. In order to confirm this, the determination process of step S22 is performed. When nmax and nmin are the same, if the height is divisible by nmax or nmin, the block shape generation device 3 can generate a block, so the determination processing in steps S23 and S24 is performed. Therefore, the same result is obtained even if the order of steps S23 and S24 is changed.
[0028]
Returning to the flowchart of FIG. 3, when it is determined in step S1 that the parameters are not appropriate, the operator is prompted to reset the parameters. After the orthogonal coordinate system as shown in FIG. 2 is set, the process proceeds to step S2. In FIG. 2, the top left vertex of the created image is the origin (0, 0). Then, the pointer is first placed at the origin (0, 0), i = 1, j = 1 (step S2), and the first block in the first column is determined by the processing from step S3.
[0029]
In step S3, it is determined whether (height-y) is smaller than bhmax. This determination is a process of determining whether or not the remaining length in the y direction, that is, the length of the current pointer in the y direction and the position of y = height is longer than the maximum block length bhmax. If (height-y) is smaller than bhmax, it is determined as no in the determination in step S3. If it is determined to be no in step S3, at least one block can be taken, so one block is defined in step S4. The width w (j, i) of this block is bw determined by the set specifications, and the length h (j, i) is determined by bhmin + RND × (bhmax−bhmin). Here, RND is a random number that generates a value in the range of 0 ≦ RND ≦ 1. Therefore, the length of the generated block in the y direction is not constant, and is determined within the range of bhmax and bhmin. At the same time, the coordinates of the pointer are registered as the coordinates X (j, i) and Y (j, i) of the upper left corner of the j-th column i-th block.
[0030]
Since the processing is performed as described above, the block generated at this time is the block number of the number of rows and columns having the values of j and i, the coordinates of the upper left corner of the block, the width w (j, i), and the length. It is uniquely defined by h (j, i). This is data relating to the block.
[0031]
When the block shape generator 3 generates one block in this way, next, in step S5, the position of the pointer is left in the x direction, the y direction is moved to y + h (j, i), and further The value of i is incremented by 1 as i = i + 1, and the process returns to the determination process in step S3 to perform the process of generating the j-th column i + 1th block. That is, as long as it is determined in step S3 that (height−y) ≧ bhmax, the processes in steps S4 and S5 are repeated. If it is determined in step S3 that (height−y) <bhmax, steps in and after step S6 are performed. Processing will be performed.
[0032]
Next, an example will be described. As shown in FIG. 5, a block is generated for the first column, and the position indicated by P in FIG. 5 (x = 0, y = y _ji ) And the position y in the y direction of point P _ji And y = height is the length Δy. At this time, if Δy is equal to or greater than the maximum block length bhmax, at least one block can be generated in Δy of FIG. 5, so that it is determined to be no in step S3 and the block is defined in step S4. In step S5, the pointer is moved and i is increased. If Δy in FIG. 5 is less than bhmax, the block length h (j, i) determined in step S4 is included in Δy. ) Cannot be taken, it is determined yes in step S3, and the process proceeds to step S6.
[0033]
In step S6, it is determined whether (height-y) is larger than bhmin. This determines whether or not Δy in FIG. 5 can take the minimum block length. When it is determined that no, the j-th column has a range of bhmin ≦ block length ≦ bhmax. Since all the blocks will not fit, in step S7, the pointer position is returned to the position of y = 0 in the y direction without changing the position of the pointer, and the block number of the jth column is set to i = 1. Returning to S3, the block generation process for the first column is performed again. That is, the processes in steps S3 to S7 are repeated until all the block shapes generated in one column satisfy the condition of bhmin ≦ block length ≦ bhmax.
[0034]
If “yes” is determined in step S6, it becomes possible to insert a block into Δy in FIG. 5, so that the process proceeds to step S8 to define the last block in the first column. That is, since Δy in FIG. 5 is not less than bhmin and less than bhmax, the last block in the first column is defined here, and the position of the pointer is (0, y _ji ), Block width w (j, i) is bw, block length h (j, i) is height-y _ji It becomes. In step S8, a numerical value is also given to each variable of the column number nx of the block and the block number ny (j) of the j-th column. nx = j indicates that the block columns up to the j-th column have been generated, and finally nx indicates the number of columns of the block pattern. ny (j) = i indicates that i blocks are generated in the j-th column.
[0035]
Then, the block shape generation device 3 moves the position of the pointer by the block width bw in the x direction, returns it to the position of y = 0 in the y direction, and sets the value of i to i = 1. At the same time, the value of j is incremented by 1 (j = j + 1) (step S9). Therefore, when the pointer is at point P in FIG. 5 and Δy is not less than bhmin and less than bhmax, the pointer is moved to the position indicated by Q in FIG. 5, that is, the top position of the second column, and step S3 is performed. Returning to this, generation of blocks is performed for the second column.
[0036]
The block shape generation device 3 repeats the above processing until the x position of the current pointer exceeds the x-direction width width of the created image determined in the specification setting. (Step S10)
[0037]
When it is determined yes in step S10, a block pattern in which a plurality of blocks as shown in FIG. 6A are arranged is created. In FIG. 6, the numbers in parentheses indicate the number of blocks and the number of blocks. The length of the block pattern in the vertical direction (y direction) is height, but the length in the horizontal direction (x direction) is not necessarily the width determined by the specification setting, but the block width determined by the specification setting. Only when bw is a divisor of width, the horizontal length of the block pattern is width.
[0038]
When all the blocks are generated within the set image size, a seamless process for eliminating the boundary line is performed in step S11. This seamless process will be described with reference to the flowchart of FIG.
[0039]
First, variables i and j are initialized (step S31), and processing starts from the first block in the first column. Subsequently, offset which is an offset amount for shifting the block is determined (step S32). The offset is determined by RND × bhmax. RND is a random number generated in the range of 0 ≦ RND ≦ 1. Here, all the blocks in the j-th column are shifted by a predetermined offset amount.
[0040]
Next, the operation of shifting the block by the offset amount offset determined in step S21 is performed. This is performed by adding offset to the y coordinate Y (j, i) of the upper end of the j-th row i-th block (step S33).
[0041]
In step S34, it is determined whether i is equal to ny (j). That is, it is determined whether or not processing has been performed for all blocks in the j-th column. If it is determined to be no, i = i + 1 and i is increased by 1 (step S35), and the process of step S33 is performed again. If “yes” is determined in step S34, the processing has been performed on all blocks in the j-th column, and the process proceeds to step S36.
[0042]
In step S36, it is determined whether j is equal to nx. That is, it is determined whether or not the processing has been performed for all the columns of the block pattern whose number of columns is nx. Here, if it is determined to be no, i = 1 and j is increased by 1 with j = j + 1 (step S37), and the process of step S32 is performed again. If “yes” is determined in step S36, the process has been performed for all the columns of the block pattern, and the seamless process is terminated.
[0043]
The block pattern shown in FIG. 6A is shifted by the offset amount in the y direction for each column as shown in FIG. The downward arrow in FIG. 6B indicates the offset amount, but the offset amount differs depending on each column. In the block shape generation device 3, the portion that protrudes from the original block size (the lower broken line portion in FIG. 6B) of the block pattern of FIG. 6B is assigned to the upper portion of the block size that is blank, A block pattern as shown in FIG. 6C is created and displayed on the display device 7. When actually printing on a product, a state in which a large number of block patterns are arranged is printed. However, when two block patterns shown in FIG. 6C are arranged vertically, as shown in FIG. Become. In FIG. 6D, the portion indicated by the left and right arrows becomes a joint, but the boundary line disappears. Compared with FIG. 12 (b) described above, the effect of the present invention can be clearly understood.
[0044]
Now, the operator observes the block pattern displayed on the display device 7 to determine whether the block is as desired. If not desired, the operator activates the block shape correcting device 5, takes in data relating to the block generated from the block shape generating device 3, and waits for the correction operation by the operator.
[0045]
When correcting the block shape, the operator drags the horizontal bar of the block to be corrected in the block pattern displayed on the display device 7 and moves it up and down by a desired amount. For example, as shown by the arrow in FIG. 8, the i-th block B in the j-th column _ji And i + 1 block B _{ji + 1} If the horizontal bar at the boundary is dragged, at this time, the block shape correcting device 5 determines which column in which column the dragged horizontal bar belongs based on the data relating to the block. In FIG. 8, the dragged horizontal bar is the i-th block B. _ji And the i + 1th block B _{ji + 1} Also belongs to. Therefore, in this case, the block shape correcting device 5 indicates that the horizontal bar is the i-th block B. _ji And the i + 1th block B _{ji + 1} It is judged that it belongs to.
[0046]
Then, if the horizontal bar is dragged in FIG. 8 and is moved upward by δ to the position indicated by the broken line in the figure, the block shape correcting device 5 detects the movement amount, and the block B _ji , I + 1-th block B _{ji + 1} Change the data. In this case, the block shape correcting device 5 _ji For, the pointer coordinates and block width remain the same, the block length is shortened by δ, and the block B _{ji + 1} For, the block width is left as it is, the x coordinate is kept as it is for the pointer coordinates, the y coordinate is changed to a value smaller by δ, and the block length is further changed by δ.
[0047]
The operator can repeat the above correction operation until a desired block is obtained. When the end of the block correction process is instructed, the block shape correcting device 5 passes the data relating to the corrected block to the pasted pattern extracting device 4 and the image synthesizing device 6.
[0048]
Note that the block shape correcting device 5 can be activated at any time. As described above, not only immediately after the block shape generating device 3 generates a block, but also, for example, image composition described later is performed. Even after being broken, if the synthesized image is not desired, the block pattern used in the synthesized image is displayed on the display device 7, the block shape correcting device 5 is activated, and the above-mentioned It is possible to correct the block pattern by performing the above operation.
[0049]
Now, when the operator observes the block generated by the block shape generating device 3 or the block corrected by the block shape correcting device 5 on the screen of the display device 7, it is desirable that the operator The paste pattern extraction device 4 and the image composition device 6 are activated.
[0050]
When the pasted pattern extraction device 4 and the image composition device 6 are activated, data relating to the block is fetched from the block shape generation device 3 or the block shape correction device 5. The pasted pattern extraction device 4 also captures the pasted image input from the pasted image input device 2.
[0051]
Then, the pasted pattern extraction device 4 recognizes the number of blocks, the size of each block, and the size of the pasted image fetched from the pasted image input device 2 based on the data relating to the fetched blocks, and pastes them. The pattern to be pasted on each block is extracted from the image. An example of the processing for that is shown in the flowchart of FIG.
[0052]
First, the pasted pattern extraction device 4 recognizes the number of rows of blocks, the number of blocks in each row, and the pasted image size (step S41). Here, the number of columns of the block is nx, the number of blocks in the jth column is ny (j), and the size of the pasted image is gw (horizontal direction) × gh (vertical direction).
[0053]
Next, assuming that i = 1 and j = 1 (step S42), the pointer for extracting the paste picture for the first block in the first column is the position of (tx (j, i), ty (j, i)). Put on. Here, the x coordinate tx (j, i) and y coordinate ty (j, i) of the pointer are, for example, RND as a random number generated in a range of 0 ≦ RND ≦ 1,
tx (j, i) = RND × gw
ty (j, i) = RND × gh
(Step S43).
[0054]
Next, it is determined whether either tx (j, i) + w (j, i)> gw or ty (j, i) + h (j, i)> gh is satisfied (step S44). Here, w (j, i) and h (j, i) are the width and length of the j-th column i-th block, which is currently the extraction target of the pasted image, respectively. Therefore, in step S44, it is determined whether or not the paste picture area having the size of the block protrudes from the paste image with the position of the pointer as the upper left vertex.
[0055]
If it is determined in step S44 that the region extracted as the pasted pattern protrudes from the pasted image, the pasted pattern extraction device 4 returns to step S43 and repositions the pointer. Make a decision.
[0056]
However, if it is determined in step S44 that the region extracted as the pasted pattern does not protrude from the pasted image, the pasted pattern extracting device 4 determines that the position of the pointer is the top left vertex. Is extracted and copied, and is registered as a pasted pattern for the j-th i-th block. Then, the value of i is increased by 1 to i = i + 1 (step S45), and it is determined whether or not the increased value of i is larger than the number of blocks ny (j) in the jth column ( Step S46).
[0057]
If the value of i is ny (j) or less in the determination in step S46, the pasted pattern extraction apparatus 4 returns to step S43 and performs a process of extracting the pasted pattern for the j-th column i + 1th block. . However, if the value of i exceeds ny (j) in step S46, the value of i is returned to i = 1, and the value of j is increased by 1 to j = j + 1 (step S47). It is determined whether or not the increased value of j is greater than the number of columns nx of the block (step S48).
[0058]
If the value of j is not more than nx in the determination in step S48, the pasted pattern extraction apparatus 4 returns to step S43 and performs processing for extracting the pasted pattern for the first block in the j + 1 column. However, if the value of j exceeds nx in step S48, the pasted pattern extraction device 4 ends the process. Then, when the pasted pattern extraction apparatus 4 extracts the pasted patterns for all the blocks as described above, the pasted pattern extraction apparatus 4 passes the extracted pasted patterns to the image composition apparatus 6.
[0059]
The above is the operation when one image is input as a pasted image. However, when a plurality of images are input as pasted images by the pasted image input device 2, the pasted pattern extracting device 4 When extracting the paste pattern for each block, first, it is possible to select from which image the random image or the like is extracted, and then to perform the above-described processing on the selected image.
[0060]
On the other hand, the image synthesizing device 6 responds to each block based on the data regarding the block received from the block shape generating device 3 or the block shape correcting device 5 and the pasted pattern received from the pasted pattern extracting device 4. A pasted picture to be pasted is displayed and combined with a block image for display.
[0061]
Thus, the operator can confirm what kind of image has been obtained by observing the screen of the display device 7, and if it is not necessary to correct the image, the operator may instruct registration. When a registration instruction is given, the image composition device 6 registers the data relating to the block and the data of each pasted pattern in the storage device 8 in association with each other.
[0062]
However, if the operator wants to change the design of a certain block by observing the composite image, the operator activates the paste pattern extraction device 4 from the input device 9, instructs the correction process, and pastes the paste pattern in the composite image. Specify the point in the block you want to change. This can be done, for example, by clicking on a point in the block with the mouse.
[0063]
When the correction processing is instructed in this way and one point in the block is instructed, the paste picture extracting device 4 recognizes which block is instructed and the size of the block based on the data regarding the block. To do. Then, the paste pattern for the block is extracted. An example of the processing is shown in FIG.
[0064]
The pasted pattern extraction device 4 first checks the pasted image size (step S51), and further performs the processing of steps S52 and S53. The processes in steps S52 and S53 are the same as the processes in steps S43 and S44 in FIG.
[0065]
When a new pasted pattern for the block is extracted in this way, the pasted pattern extracting device 4 passes the pasted pattern to the image composition device 6. Then, the image composition device 6 pastes the new paste picture received from the paste picture extraction device 4 to the block and displays it on the display device 7. Then, the operator can repeat the above-described operation until a desired composite image is obtained.
[0066]
Because it is as described above, it is possible to change the paste pattern of the block by a simple operation of pointing to one point in the block where you want to change the paste pattern. It is what is done.
[0067]
The correction process of the pasted picture extraction device 4 can be started at any time. Therefore, for example, once created composite image data is read from the storage device 8 and displayed on the display device 7, By designating one point inside an appropriate block in the composite image, it is also possible to change the paste pattern of the block. At this time, the pasted pattern extraction device 4 fetches data relating to the block from the image composition device 6 and further fetches a pasted image from the pasted image input device 2 and performs the processing shown in FIG.
[0068]
As described above, according to this image creation method and apparatus, the generation of the block shape and the extraction of the pasted pattern for each generated block can be automatically performed. Compared with this, it can be greatly reduced. In addition, it is possible to easily modify the block shape and change the pasted pattern of the block.
[0069]
The image creating apparatus according to the present invention has been described above together with the image creating method. Next, the case where the created composite image is printed will be described.
[0070]
When printing the composite image created as described above, the data relating to the block used for the composite image to be printed and the data of the pasted pattern of each block are read out from the storage device 8 and loaded into a digital printing apparatus or the like. Then, a printing plate is created and printed. At this time, if the paste pattern is subjected to foaming treatment and the block pattern is printed using foam suppression ink, the paste pattern is foamed. On the other hand, the block pattern is desirable because it can suppress the foaming and become a joint, so that a tile-like image can be printed.

As is well known, the foaming treatment can be performed by coating foamable PVC on a substrate, forming a printing layer on the substrate with ordinary ink, and finally heat-treating. Moreover, in order to suppress foaming, a foamable PVC is coated on a base material, a printing layer is formed thereon with a normal ink, and further, a foam suppression region is printed with the foam suppression ink, followed by heating. What is necessary is just to process. As a result, only the area where the foam suppression ink is not applied is raised.
