Melange Yarn Image Creation Apparatus, Melange Yarn Image Creation Method, and Melange Yarn Image Creation Program

Abstract

For formation of a yarn image of melange yarn, layers of image having multiple types of fibers of differentiated colors arranged randomly are piled one upon another into a stack of multiple layers. The degree of transparency is determined from the brightness of each of the fibers, and an image synthesis is carried out with respect to the image layers piled one upon another, thereby forming a yarn image of melange yarn. Thus, a yarn image can be formed without any test production of melange yarn. Further, there can be realized a real expression of texture sensation owing to vertical piling of differentiated colors.

1 . A mélange yarn image creation apparatus for creating a mélange yarn image, characterized by: 
 means for providing a plurality of vertically overlapping image layers in which a plurality of types of fiber having different colors and a predetermined transparency are disposed at random; and    means for creating said mélange yarn image by image-synthesizing said vertically overlapping image layers in accordance with said transparency of each of said fiber types.    
   
   
       2 . The mélange yarn image creation apparatus according to  claim 1 , characterized in further comprising means for determining said transparency of each of said fiber types using a value of each of said fiber types and as an increasing function of said value.  
   
   
       3 . The mélange yarn image creation apparatus according to  claim 1 , characterized in further comprising means for modifying a resolution of said yarn image in said image layers such that a yarn image in which said fiber types are mixed evenly is created by relatively increasing said resolution of said yarn image, and a yarn image in which said fiber types are mixed unevenly is created by relatively reducing said resolution of said yarn image.  
   
   
       4 . A mélange yarn image creation method for creating a mélange yarn image, characterized in comprising the steps of: 
 providing a plurality of vertically overlapping image layers in which a plurality of types of fiber having different colors and a predetermined transparency are disposed at random; and    creating said mélange yarn image by image-synthesizing said vertically overlapping image layers in accordance with said transparency of each of said fiber types.    
   
   
       5 . The mélange yarn image creation method according to  claim 4 , characterized in that said transparency of each of said fiber types is determined using a value of each of said fiber types and as an increasing function of said value.  
   
   
       6 . A mélange yarn image creation program for creating a mélange yarn image, characterized in comprising: 
 a command for providing a plurality of vertically overlapping image layers in which a plurality of types of fiber having different colors and a predetermined transparency are disposed at random; and    a command for creating said mélange yarn image by image-synthesizing said vertically overlapping image layers in accordance with said transparency of each of said fiber types.
