Description

  The present invention, for example, when drawing an original picture created by handwriting on a textile fabric or the like in an array of patterns, especially for organizing, correcting, and displaying on a fabric a pattern lacking large pixels generated at the edge of a pattern. The present invention relates to an image correction processing apparatus for obtaining a good design and a recording medium for pattern image correction processing on which computer software for realizing the function on a computer is recorded.

  For example, as a traditional local textile industry in the southwestern part of Ibaraki Prefecture, there is Yuki woven weaving. As for the pattern drawn on the cloth of this Yuki cocoon, the original picture is drawn by hand drawing, and a unit figure called a turtle shell as shown in FIG. 9, that is, a pattern is used. The weaving thread is printed so that the turtle shell pattern is regularly arranged two-dimensionally vertically and horizontally and diagonally on the fabric, and an example pattern as shown in FIG. 12 is drawn on the fabric by the collection of the turtle shell pattern. When drawing a pattern, the shape of the tortoiseshell pattern appears completely at the center of the pattern, but the shape of the tortoiseshell pattern does not appear completely at the portion corresponding to the outline of the pattern. In this contour portion, the contour is drawn with a partial shape of each element constituting the turtle shell pattern called “pillar”, “flyer”, “mountain”, “cross”, etc. as shown in FIG. . Also, the column may be half as long as the shape of the handle. The symbol corrected in this way is the symbol shown in FIG.

  Such Yuki Saori weaving pattern processing methods currently use a mechanism for drawing design designs using image processing software on a personal computer. The image processing software used is software for processing raster images. In a raster image, pixels called pixels are regularly arranged vertically and horizontally on a two-dimensional plane according to a required resolution, and individual patterns such as the above-mentioned turtle shell are displayed.

When using image processing software of a personal computer, the original image is processed using a mask function, which is its basic function, to obtain a pattern image. The mask function is a function for displaying the drawing portion through the mask by applying a mask to the original image drawn in the drawing portion.
For example, with regard to the design of Yuki Kaoru, a mask of turtle shell is created in advance, a pattern is drawn on a virtual fabric by masking the original picture with this mask, and the weaving thread is printed from this pattern. Weave the dough.

  However, a pattern image obtained by such image processing software has a so-called pattern defect in which a part of the pattern is missing in the contour portion. Therefore, in the case of a Yuki tsumugi pattern, when it is drawn on a virtual fabric, the shape of the turtle shell pattern in the contour portion of the pattern becomes extremely rough. In order to obtain the contour pattern of the tortoiseshell pattern that should originally be, it is necessary to manually correct rough portions in each contour portion. This modification is more work as the pattern becomes more complicated.

2. Description of the Related Art Conventionally, there has been proposed a method in which irregularities or the like generated in the contour portion of an image are corrected by image processing using a computer. However, it is not necessarily suitable for correcting the contours of images displayed in a specially shaped pattern such as the Yuki turtle tortoise pattern, and it cannot be used in actual yarn dyeing and fabric weaving. .

  In view of the problems in the conventional image correction processing, the present invention provides a pattern image correction processing apparatus capable of automatically correcting a pattern of a contour portion of a pattern image by a simple operation without using manual operations, and the same It is an object of the present invention to provide a recording medium for pattern image correction processing in which software capable of realizing functions on a computer is recorded.

In the present invention, the first pattern image and the original image that was created masked with a first mask, regularly arranged the pattern displayed in a predetermined shape as a whole by a predetermined pixel group follow the original vertically and horizontally by hand the Ru obtained. Further , except for the pattern in which the pixels mainly in the edge portion of the first pattern image are largely missing, a pattern having no defect at other pattern positions is reproduced. Therefore, a second mask in which virtual windows for detecting a part of the pattern of the first pattern image are arranged is used. The first pattern image is masked with this second mask, for example, a complete pattern is given only at the position where the pattern is detected , and no pattern is given at the position where the pattern is not detected.

A pattern image correction processing device according to the present invention is a device that corrects a portion of a pattern displayed in a two-dimensional array such as repeated vertical and horizontal diagonals of the same pattern and lacks the pattern of the same pattern, and has a virtual shape of the same shape. A first mask in which windows are regularly arranged vertically and horizontally, and a second mask in which virtual windows narrower than those windows are coordinately aligned with the individual windows of the first mask and are regularly arranged vertically and horizontally; Processing means for masking the original image with the first mask to obtain a first pattern image; processing means for masking the first pattern image with the second mask to obtain a second pattern image; and Pattern placement means for placing the first pattern at a position corresponding to the coordinates of the second pattern image to obtain a third pattern image.

The pattern of the pattern image is displayed by a plurality of pixel groups. The second mask has a virtual window that corresponds only to a portion of the virtual window of the first mask. A plurality of second masks are provided for having windows corresponding to different portions of the windows of the first mask.

In such a pattern image correction processing device, the first pattern is arranged on the coordinates according to the original image by the first mask, and the first pattern image corresponding to the original image is obtained. Then, using a second mask positioning the first and windows of the window is smaller than the virtual in the same arrangement as the virtual window of the mask, masking the first pattern image, the first pattern image A second pattern image is obtained by arranging another second pattern only at the position where the pattern is detected . For example, in the simplest case, when the pattern is a circle or square, only the narrow pixel at the center is masked with the second mask to obtain the second pattern image.

Then re-place the complete first pattern shape with no chipping at the position of the second pattern image pattern, to obtain a third pattern image. Then, even if there is a missing pattern in the contour portion of the first pattern image, the complete first pattern is rearranged at the position where the second pattern exists in the second pattern image. On the other hand, the first pattern is not rearranged at a position where there is no second pattern in the second pattern image. As a result, in the portion of the pattern that occupies a certain pixel in the missing pattern of the first pattern image, the missing pattern is complemented as a complete pattern, and in the portion of the pattern that does not occupy a certain pixel, The missing pattern is removed. As a result, the pattern is complemented and deleted particularly at the contour portion of the pattern image, and a corrected second pattern image is obtained.

  The pattern image correction processing step in such a pattern image correction processing apparatus can be easily realized by automatically processing an image captured by a computer using a virtual mask. The means for realizing such a function on a computer is configured as a computer program, and the fact that it has been recorded can be set up in the computer by a recording medium.

  Since the present invention can automatically correct the pattern of the contour portion of the pattern image by a simple operation without any manual work, for example, in the background processing of the Yuki tsumugi pattern representing the pattern by the arrangement of the turtle shell pattern, etc. A marked improvement in efficiency can be achieved. In particular, the pattern of the contour portion of the pattern image can be easily corrected regardless of the complexity of the pattern.

The present invention uses a masking function used in an image processing method in a computer, and automatically corrects a pattern defect particularly in an outline portion of an image displayed by regularly arranging patterns having a certain shape. I made it possible.
Hereinafter, examples of the present invention will be described in detail with specific examples with reference to the drawings.

  FIG. 1 is a block diagram showing the configuration of the image correction processing apparatus according to the first embodiment of the present invention. In the figure, reference numeral 1 denotes an entire image correction processing apparatus according to the embodiment, and includes a control unit 2, a display unit 3, a video memory 4, a keyboard 5, and a pointing device 6 such as a mouse as main components. Further, an image input device 12 such as an image scanner or a digital camera for capturing an original image created by handwriting or the like is also attached. These components are connected to each other via a system bus 7.

  The control unit 2 controls the entire image correction processing apparatus 1 according to the present embodiment. The control unit 2 includes a CPU 8 such as a microprocessor, a program memory 9 including a RAM, an I / O interface unit 10, a hard disk device, and an optical recording device. An external storage device 11 such as a reproduction drive is provided. The CPU 8 controls the entire apparatus 1 according to a program stored in a program memory 9 represented by a flowchart described later. The program memory 9 stores the program and is also used as a work area for storing mask data and various data when the CPU 8 executes control processing, and includes a temporary interpolation area for various data.

  In this embodiment, the I / O interface unit 10 performs interface control with a hard disk device as the external storage device 11. The hard disk device is an external storage device 11 that records and reads / writes data on a magnetic recording medium on the disk, and stores the created image data and various application programs that are downloaded to the program memory 9 and executed. Yes.

  The display unit 3 displays input symbols, processed symbols, messages to the operator, etc. on the screen, and is composed of a CRT or liquid crystal. The video memory 4 stores image data to be displayed on the screen of the display unit 3. Both the keyboard 5 and the pointing device 6 are operated by an operator to input various data and instruction commands. The image input device 12 captures an original image created by handwriting or the like, and devices such as an image scanner and a digital camera are used.

  Next, graphic processing in the image correction processing apparatus 1 of the present embodiment will be described with reference to the flowchart of FIG. 2 and the image diagrams shown in FIGS. Note that the image diagrams shown in FIGS. 3 to 8 show the symbols displayed using the simplest square pattern as the pattern so that the process of the symbol correction process can be easily understood.

  First, prepare the original picture. The original image is a technique of taking a handwritten image into the image correction processing device 1 that is a computer by the image input device 12 or using image creation software set up in the image correction processing device 1, and a pointing device such as a keyboard 5 and a mouse. 6 and recorded in the external storage device 11. Such an original picture is displayed on the display unit 3 by pixels (pixels) arranged on the screen with a required resolution. An example of the original picture is shown in FIG.

Next, the original image is masked using the first mask built in the image correction processing apparatus 1 which is a computer. For example, the first mask is as shown in FIG. 4, in which virtual windows of the same shape are regularly arranged in the vertical and horizontal directions in order to extract the pixels as the pattern from the original picture. In the example of FIG. 3, square windows are arranged vertically and horizontally at regular intervals. By masking the original image with this first mask, the design is displayed by the vertical and horizontal arrangement of the first pattern of the same shape displayed by the set of a plurality of pixels. FIG. 5 shows a first pattern image obtained by masking the original image with the first mask in this way.

Next, the first pattern image is masked by using a second mask built in the image correction processing apparatus 1 which is a computer. For example, the second mask is as shown in FIG. 6 and has virtual windows arranged at the same interval as the first mask, and each window is coordinated with the virtual window of the first mask. In the corresponding position. However windows of the second mask is sufficient from the virtual window of the first mask small windows that virtual corresponds Zorezore to a portion of the virtual window of the first mask. Most commonly, the virtual window of the first mask corresponds to the center position of the virtual window of the second mask, respectively. In the example of FIG. 6, the second mask has dot-like virtual windows arranged at regular intervals in the vertical and horizontal directions at the same intervals as the virtual windows of the first mask. It corresponds to the center position of the latter virtual window.

When masking the first pattern image by the second mask, for example as in the central portion of the first pattern image, the partial pixels constituting the first pattern is substantially aligned, the second mask On the second pattern image, a dot-like second pattern is displayed . On the other hand, for example, when the pixels constituting the first pattern are not partially present and only partially, such as the contour portion of the first pattern image, the following results are obtained. First, when the pixel of the first pattern exists in the center corresponding to the virtual window of the second mask , the dot-like second pattern is arranged on the second pattern image by the second mask . . On the other hand, the dot-like second pattern is not arranged on the second pattern image in the portion where the pixel does not exist in the central portion of the first pattern corresponding to the virtual window of the second mask. When the first pattern image as shown in FIG. 5 is masked by the second mask as shown in FIG. 6 in this way, the first pattern in which some pixels are missing as in the outline portion of the first pattern image. For, individual patterns can be screened according to the ratio of the remaining pixels. The second pattern image obtained as a result is shown in FIG.

Finally, the third pattern image as shown in FIG. 8 is obtained by rearranging the pixels of the complete first pattern in which no pixels are missing around the dot-like second pattern of the second pattern image. Is obtained. This third pattern image includes all the first pattern pixels including the outline portion, and all the patterns constituting the image are complete first patterns without any defects. The pattern image correction is thus completed.

These processes are all performed by computer image processing. The original image, each pattern image, and the virtual mask are recorded in the external recording device as different layers, appropriately read into the program memory, displayed on the computer screen, and the image and the mask are overlaid. Correction processing is performed.
Programming that achieves such a function is recorded on a recording medium such as an optical recording medium, and the programming can be set up by the function of the basic software (OS) of the personal computer.

  Next, the case where the image correction processing method according to the present invention is applied to the correction processing of the woven pattern of Yuki cocoons using the turtle shell pattern as shown in FIG. 9 as individual patterns will be described. Since this is basically the same as the pattern image correction process using the square pattern described above, the description will mainly focus on the differences.

  As already described with reference to FIG. 9, the turtle shell pattern of Yuki Pass is basically hexagonal, and is composed of elements called “pillars”, “flyers”, “mountains”, “crosses” and the like. In Yuki Pass, adjacent turtle shell patterns are adjacent horizontally, vertically, and diagonally in the design of the fabric, and each adjacent turtle shell pattern shares the elements of "pillar", "flyer", and "mountain".

First, the original image is prepared in the same manner as in the above example, and is created in the same manner as in the above example. FIG. 10 shows an example of the original picture.
Next, the original image is masked using the first mask built in the image correction processing apparatus 1 which is a computer. This first mask is as shown in FIG. 11, and the turtle shell pattern of Yuki is regularly arranged in the horizontal, vertical, and diagonal directions. By masking the original image with this first mask, the original image is displayed as an array in the horizontal, vertical, and diagonal directions of the turtle shell pattern. FIG. 12 shows a first pattern image obtained by masking the original image with the first mask in this way.

  Next, the original image is masked using the second mask built in the image correction processing apparatus 1 which is a computer. For example, the second mask is as shown in FIG. 13 and has virtual windows arranged at the same interval as the first mask. However, this window masks only a part of the elements of the turtle shell pattern, and this individual virtual window corresponds to the position of each corresponding turtle shell pattern element of the first mask. For example, the masking pattern of the second mask shown in FIG. 13 is an inverted T-shape that includes only the lower half of the column of the turtle shell pattern shown in FIG. The virtual windows of the lower half of the second mask column and the lower mountain component of the second mask correspond to the positions of the lower half of the first mask column and the lower mountain of the first mask.

  When the first pattern image is masked by the second mask, only the elements of the turtle shell pattern of FIG. 12 are extracted by the inverted T-shaped virtual window of the second mask. After masking, the length of each element of the lower half of the column of the tortoiseshell pattern and the lower end of the column determines whether to add or delete those elements. Of course, those elements are added to the portions where the lengths of the elements appear completely on the masking image, and those elements are not added to the portions where the elements do not appear at all. Further, when the length of each element is incomplete, it is determined by whether or not the pixel of that element exists at a predetermined point of each element. One of them is stored in advance in the channel function, which is the basic function of the image processing software. The channel function is a function that saves the mold and is not usually displayed on the screen.

Processing is performed in this way, the lower half of the column of the tortoiseshell pattern and the lower end of the column are added to the points to be added, incomplete elements are removed from the other points, and the pixel of each element is processed there. The pattern image shown in FIG. 14 is rearranged.
Further, other elements are also provided with a second mask and the same processing is performed. The plurality of second masks are recorded on different layers together with the channel function, and sequentially called and processed.

  By processing all the elements of the tortoiseshell pattern in this way and rearranging the pixels, a tortoiseshell pattern image as shown in FIG. 15 is obtained. This tortoiseshell pattern image corrects the tortoiseshell pattern missing at the contour part, and when this is printed on the binding yarn as an original image and the woven fabric is woven, the contour part tortoiseshell pattern that appears on the fabric is Don't get rough.

  In the example described above with reference to FIGS. 3 to 8, each square pattern was masked with one second mask and processed. On the other hand, in this example of the turtle shell pattern, each element of the turtle shell pattern is treated as an individual pattern, and the process is repeated individually or several by a plurality of second masking. The only difference is that there is no significant difference in basic ideas and procedures.
