Problems solved by technology

For example, it is difficult to empirically determine the blending of mixed-color yarns or the color vector of yarns from sample knitted fabrics
Although it is considered to disassemble the sample knitted fabric to read the image of the knitted yarn, it is labor-intensive and disassembles the sample knitted fabric

Embodiment Construction

[0059] Figure 1 ~ Figure 12 Represents an embodiment. in figure 1 Among them, 2 is an image simulation device, 4 is a bus, and 6 is a color scanner, which can also be replaced with a digital camera to read the color image of the sample knitted fabric knitted from mixed color yarn. 8 is a frequency distribution diagram generating unit that generates a frequency distribution diagram of the distribution of color values ​​of the read color image. For example, the color space used is a space composed of HLS, the color space merging part is divided into 12 equal parts by the hue H, the color space is divided into 8 equal parts by the luminance L, and the color space is divided into 8 equal parts by the chromaticity S. In this way, the overall color space Divided into 768 groups. Then, after removing unnecessary parts in the color image from the read color image by the sampling unit 18, each pixel of the color image is classified into 768 groups to generate a frequency distribution...

Abstract

Color image of a fabric of melange yarns is read in, a sampling range is determined and histogram of a color value is made. Spice color is extracted for each hue in the histogram and other colors are merged as normal colors in order to decrease the number of colors thus decreasing the number of normal colors constituting melange yarns. Histogram of the color value of melange yarns is simulated bythe normal color and its frequency and the spice color and its frequency. Image of melange yarns can be simulated from a fabric sample of melange yarns.

Description

technical field [0001] The present invention relates to a technique for simulating a yarn image of a melange yarn used by a knitted fabric using the melange yarn. Background technique [0002] Melange yarn is a yarn made of a variety of fibers with different colors. A yarn with a unique impression can be obtained by appropriately selecting a combination of colors of fibers. The color and proportion of the various fibers that make up the melange yarn are called blending. [0003] In the apparel industry, we carry out product planning or order melange yarns with small samples of knitted fabrics using melange yarns. However, in knitted fabric samples, it is not possible to simulate finished garments such as outerwear using melange yarns. Therefore, there is a distance between the sample knitted fabric of melange yarn and the actual finished product. [0004] Yarn images of melange yarns are required for the simulation of finished garments, and it is not easy to generate ya...
