DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the drawings.
(Outline of mosaic image creation system according to this embodiment)

  As shown in FIG. 1, a mosaic image creation system (hereinafter simply referred to as “this system”) 100 according to the present embodiment includes a server device 110 and a mosaic image creation device (hereinafter simply referred to as “creation device”). 1. The system 100 receives image data 180 from a user 260 and creates a mosaic image 32 using the imitation jewelry 24 such as rhinestones as a raw material and the image data 180 as an original image.

The server device 110 is connected to the user terminal 250 via the communication network 240, acquires the image data 180 from the user terminal 250, and controls the creation device 1 to create the mosaic image 32 based on the image data 180. An instruction 34 is created. On the other hand, the creation device 1 creates the mosaic image 32 with the imitation gem 24 on the substrate 30 by installing the imitation gem 24 on the substrate 30 in accordance with the control instruction 34 notified from the server device 110.
(Operational principle of server device according to this embodiment)
The operation principle of the server device 110 according to the present embodiment will be described with reference to FIGS. FIG. 2 is a functional block diagram of the server device 110.

  As shown in FIG. 2, the server apparatus 110 includes an image data acquisition unit 112, a jewel information storage unit 120, a color distance calculation unit 130, a jewel allocation unit 140, a contour extraction unit 150, a dithering unit 160, and an arrangement information notification unit 170. Have

  The image data acquisition unit 112 acquires image data 180 that is an original image of the mosaic image 32 from the user terminal 250 via the communication network 240. As shown in FIG. 3, the image data 180 is general image data, and is image data in a format in which color information based on, for example, an RGB color model is defined for each pixel.

  Here, the data format of the image data 180 is not particularly limited as long as color information is specified for each pixel constituting the image data 180. As shown in FIG. 4, the arrangement format of the pixels constituting the image data 180 may follow any arrangement rule shown in (a) to (c), or may follow other arrangement rules. . Further, the image data 180 may be configured to selectively limit the processing target portion of the server apparatus 110, or may be obtained by appropriately enlarging / reducing the original data.

  The jewel information storage unit 120 stores jewel identification information 210 for identifying the color of the imitation jewel 24 and color information for specifying the color of the imitation jewel 24 in association with each other. Here, the color information may be color information defined by the RGB color model, or may be color information defined by another model. As shown in FIG. 5, the jewel information storage unit 120 adopts, for example, an RGB color model, (jewel identification information 210, R <red> element, G <green> element, B <blue> element) = (red , 255, 0, 0), (green, 0, 255, 0),..., (Color A, 50, 100, 150).

  That is, the jewel information storage unit 120 stores information for specifying the color of each imitation jewel 24 for each imitation jewel 24 having a different color. Here, the color of the imitation jewel 24 varies depending on the observation position among the imitation jewels 24, and there is a background that the quality of the mosaic image 32 is determined by the contents defining the color. Therefore, the beauty of the mosaic image 32 can be adjusted by adjusting the color information stored in the jewelry information storage unit 120. For example, the color information stored in the jewel information storage unit 120 may be an average value of color information in all pixels of image data obtained by photographing the imitation jewel 24 from the plane direction. The color of the imitation jewel 24 varies depending on the observation position because the imitation jewel 24 is processed and polished such as facets and cuts.

  The color distance calculation unit 130 calculates the color distance 200 between the color information of one pixel and the color information corresponding to all the gem identification information 210 stored in the gem information storage unit 120 for each pixel constituting the image data 180. calculate. For example, when the number of pixels of the image data 180 is 100, and 50 pieces of gem identification information 210 are stored in the gem information storage unit 120, the color distance calculation unit 130 has 50 pixels per pixel. The color distance 200 is calculated, and for the entire image data 180, the number of pixels 100 (number) × 50 (number) = 5,000 is calculated.

  When the RGB color model is adopted, the color distance color distance calculation unit 130 calculates a color distance 200 between two points (here, a color distance between AB) according to (Equation 1).

  The jewel assigning unit 140 assigns jewel identification information 190 corresponding to the minimum value in the color distance 200 calculated by the color distance calculating unit 130 to each pixel constituting the image data 180. That is, the gem assigning means 140 assigns the imitation gem 24 having the closest color when replacing each pixel constituting the image data 180 with the imitation gem 24.

  The contour extraction unit 150 performs edge detection processing on the image data 180, detects (extracts) pixels constituting the contour line in the image data 180, and indicates a flag indicating that the detected pixel is a contour line (Identification information) is given.

  The dithering means 160, for each pixel constituting the image data 180, jewel identification information 190 assigned to the processing target pixel 220 and jewel identification information 190 assigned to the pixels 230 located around the processing target pixel 220, And whether the difference between the color information of the processing target pixel 220 in the image data 180 and the color information of the peripheral pixel 230 in the image data 180 is equal to or greater than a predetermined value.

  Subsequently, the dithering unit 160 identifies the gem corresponding to the second smallest value in the color distance 200 calculated by the color distance calculation unit 130 for the processing target pixel 220 determined to satisfy the two conditions described above. Information 190 is newly allocated. That is, the dithering means 160 replaces the jewel identification information 190 once assigned to each pixel by the jewel assigning means 140 with the jewel identification information 190 different from that assigned by the jewel assigning means 140 for the pixels satisfying the predetermined condition. Perform the process.

  As shown in FIG. 6, eight pixels 230 are arranged around the processing target pixel 220. However, in the processing performed by the dithering unit 160, all eight pixels may be used as the pixel 230. For example, a mode in which two pixels located on the left side and the upper side of the processing target pixel 220 are selectively used may be used. Accordingly, in the processing performed by the dithering means 160, “how many pixels” are used as the pixels 230 can be appropriately determined.

  Note that the dithering unit 160 may be configured to exclude the pixel to which the flag indicating the contour line is given by the contour extracting unit 150 from the processing target pixel 220.

The arrangement information notifying unit 170 generates gem arrangement information 210 in which each pixel position in the image data 180 is associated with the gem identification information 190 assigned by the gem assigning unit 140 and the dithering unit 160, and via the communication network 240. Then, the jewel arrangement information 210 is notified to the creation device 1.

Only the imitation jewel 24 directed in a predetermined direction is extracted by removing it by sweeping. In this case, the orientation of the extracted imitation jewel 24 can be changed in any way by devising the shape of the hole 40 provided in the plate-like body 36.

  Further, consider a case in which the posture changing means 4 advances the imitation jewelry 24 on the conveyance path 38. In this case, the sorting means 6 changes the shape of the conveyance path 38 from the entrance to the exit, and guides the imitation jewel 24 to the hole-shaped receiving port 40 in which only the imitation jewel 24 facing a predetermined direction is accommodated. The imitation jewel 24 facing a predetermined direction is extracted. The sorting means 6 can remove the imitation jewel 24 that faces in a direction other than a predetermined direction. Here, the shapes of the conveyance path 38 and the receiving port 40 are sequentially changed along the traveling direction of the imitation jewelry 24.

  The sorting means 6 extracts the imitation gemstone 24 in a desired direction and appropriately adjusts the timing of guiding the imitation gemstone 24 to the receiving port 40 by appropriately adjusting the shape of the conveyance path 38 and the receiving opening 40. The imitation jewel 24 can be removed. Again, the shapes of the conveyance path 38 and the receiving port 40 change sequentially along the traveling direction of the imitation jewelry 24.
