  In the present invention, an original image is displayed on a color monitor, an extraction area is designated, colors in the extraction area are extracted, and an array of color values is obtained. This array is expanded and displayed as a preview image as a border pattern. The operator changes the color extraction area according to the preview image, and when the color extraction area is confirmed, the extracted color is developed into a stripe pattern to form a border pattern. This makes it easy to create a border pattern. Furthermore, since a wide variety of images such as landscape images, animals and plants can be used as the original image, a novel and original border pattern can be easily designed. In addition, since the color extraction area can be changed while checking the preview image, it is possible to easily create a border pattern that can be accepted by the operator.

  The border pattern is an important pattern in the design of the knitted fabric, and can be converted into a pattern that can be knitted by a knitting machine by limiting the number of colors of the created border pattern.

  In the following, an optimum embodiment for carrying out the present invention will be shown.

  1 to 3 show a border pattern design device, a design method, and a design program, taking the knit design device 2 as an example. The knit design apparatus 2 is realized by an appropriate computer, 4 is a bus, 6 is an image input, for example, an image input by a scanner or a digital camera. 8 is a color monitor, 10 is a keyboard, 12 is a stylus, and a mouse may be used. The operator designates the color extraction area by designating an area on the color monitor 8 with the stylus 12 or the like. The color extraction area may be, for example, a straight line, a free curve, or a figure with a width such as a rectangle. Further, the operator can move or rotate the color extraction area on the original image, and can change the length or bend it.

  The color extraction unit 14 extracts colors from the color extraction area designated by the stylus 12 and outputs an array of colors. For example, when the color extraction area is a straight line having a width of 1 pixel, the color of each pixel is extracted as it is. When the color extraction area is a free curve with a width of 1 pixel, the color of each pixel is extracted along the free curve. When the color extraction area is a figure having a width corresponding to a plurality of pixels such as a rectangle, for example, an average of colors of a plurality of pixels in the width direction is output.

  The image operation unit 16 develops the color arrangement extracted by the color extraction unit 14 in a stripe pattern parallel to the vertical direction or the horizontal direction, for example, to form a border pattern. Further, the image operation unit 16 rotates the color development direction by, for example, 90 °, converts the color extracted by the color extraction unit 14 in the color space, deletes or changes the color specified by the operator in the border pattern, etc. Perform the operation. The color image developed in a striped pattern by the image operation unit 16 is displayed as a preview image on the monitor 8, and the operator can change or confirm the color extraction area using a pointing device such as the stylus 12.

  A preview data storage unit 18 stores a border pattern preview image created by the image operation unit 16 or a color array obtained by compressing the border pattern preview image. When the preview image is determined, the design data storage unit 20 stores this as design data. Note that the preview data storage unit 18 and the design data storage unit 20 may be a single storage unit, and the preview image and the design image may be handled as the same image. A pattern data storage unit 22 stores pattern data representing the shape of the knitted fabric. Even if the shape of the knitted fabric is rectangular or the shape of each part such as the front and back of clothing such as a sweater, it is equipped with a front and back body, etc. It may be connected.

  The unfolding unit 24 unfolds the design data in the knitted pattern when the operator confirms the color extraction area, and fills the knitted pattern with a border pattern. The data conversion unit 26 converts the pattern data in which the border pattern has been developed by the development unit 24 into knitting data. In the knitting of the border pattern, the border pattern is realized by switching the carrier for supplying the colored yarn. Therefore, preferably, the knitting data includes a carrier control command and a color image of the yarn supplied to each carrier. The number of courses that are knitted using carriers is preferably an even number for each carrier. The knitting data is converted into a simulation image in which individual loops of the knitted fabric are realistically represented by the loop simulation unit 28, and displayed on the color monitor 8, for example. The knitting data is converted into knitting data of a knitting machine such as a flat knitting machine 32, and is output by communication or via the removable disk 30 or the like. The data conversion unit 26 does not necessarily need to create knitting data that can drive the actual flat knitting machine 32, and it is sufficient if the loop simulation unit 28 can create knitting data sufficient to create a loop simulation image.

  FIG. 2 shows processing from input of a natural image as an original image to development of a border pattern into pattern data. Natural images such as landscapes, plants, animals, etc. can be input with a digital camera or scanner, or taken out from the library. Next, the natural image is displayed on the color monitor, and the operator designates the color extraction area with a pointing device such as the stylus 12. In FIG. 2, when a linear color extraction area is designated and the operator designates a straight line, the line width is set to one pixel, which is a line segment of a section designated by the operator. In addition to this, when a free curve is drawn with a stylus, the free curve is equivalent to one pixel width. When a rectangular shape or the like is designated as the color extraction area, for example, the color values in the width direction are averaged, and the average color values are arranged along the longitudinal direction of the rectangle.

  The extracted array of color data is stretched in parallel in a striped pattern, converted into design data such as horizontal stripes or vertical stripes, and displayed on the color monitor 8 as a preview image. On the other hand, the operator performs operations such as changing the color extraction area by stretching, shortening, bending, etc., rotating the stripe direction, for example, 90 °, changing the color value, or deleting the specified color. Can do. When the color extraction area is confirmed and other processing such as color value change or deletion is completed, a border pattern is obtained. When the obtained border pattern is used as print data, it can be used as it is.

  However, when used for knitting data, there is a limit to the number of colors that can be used on the knitting machine. That is, when there are more colors than the limit in the border pattern, the adjacent colors are combined into one color, and the total number of colors is within the limit. For example, the operator may designate a desired area in the border pattern in which the number of colors is limited, and create the border pattern by expanding the area so as to repeat. This is an example of editing a border pattern using only a desired area in the original border pattern. Next, the border pattern is developed by filling the pattern data shown in the lower left of FIG. Processing for the convenience of knitting by the flat knitting machine 32 may be performed. For example, when knitting a row of stitches while supplying colored yarn from a carrier is called one course, the number of courses is preferably an even number for each colored yarn. Therefore, the developing unit 24 makes corrections such as making the number of courses for each color yarn an even number. Although the front body of the sweater is displayed in FIG. 2, it is also preferable to develop a border pattern on the front body and the back body in the same way for knitted fabrics in which the front body and the back body of the sweater are seamlessly connected. .

  FIG. 3 shows a border pattern design program 40 according to the embodiment. The program 40 is to be executed by a computer such as a knit design apparatus equipped with an original image input means, a color monitor, and a stylus or mouse for specifying a position on the color monitor. The program 40 implements the color extraction unit 14, the image operation unit 16, the development unit 24, and the like on the knit design apparatus 2 in FIG. 1 on an appropriate computer. The color extraction area acceptance command 41 accepts that an operator specifies a color extraction area for a natural image displayed on a color monitor, and accepts a change or confirmation of the color extraction area when a preview image is displayed. . The color extraction instruction 42 extracts a color from a color extraction area that is temporarily designated or confirmed. The preview image creation command 43 creates a preview image in which the extracted colors are arranged in a striped pattern, and displays it on a color monitor. The image operation command 44 rotates the color extraction area, for example, 90 °, converts the color in the color extraction area or the preview image in the color space, deletes or changes the color specified by the operator, extends the color extraction area, Perform operations such as shortening or bending. The unfolding instruction 45 restricts the types of colors in the border pattern, repeats the border pattern so as to fill the pattern of the knitted pattern, and uses it as knitted design data. The design data can be converted into knitting data by the data converter 26 in FIG. 1 and used for loop simulation and knitting machine control.

In the embodiment, the following effects can be obtained.
(1) Since a wide variety of original images such as landscapes, animals, and plants can be used, the range in which border patterns can be created is extremely wide.
(2) When creating a border pattern, it is only necessary to specify a color extraction area on the color monitor, and the operation is simple.
(3) The color extraction area and the like can be changed until a border pattern that the operator can agree with is obtained.
(4) This makes it easy to design innovative and diverse border patterns.
(5) The border pattern is an important design for the knitting, and the design of the knitting becomes easy.

In the embodiment, an example in which the created border pattern is used for the knitting data is shown, but the present invention is not limited to this. The border pattern can also be used for print data such as knitted fabric, woven fabric, and curtain.
