Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the production of line drawing relief patterns used for the purpose of preventing counterfeiting of banknotes, stock certificates, bonds, and other securities.

[0002]

2. Description of the Related Art In securities, a line drawing relief pattern by a line drawing expression is often used on a ticket surface in order to provide a forgery prevention effect. For this line drawing relief pattern,
A relief is made by sculpture clay or hand-carved sculpture, and this is called a stylus-type relief engraving machine. It is traced in the X direction by scanning, and the vertical movement of the stylus in the Z direction at that time is changed in the Y direction. By converting into a variation, the original relief was reproduced as a line drawing relief pattern on a two-dimensional plane as a displacement of a straight line group. Such a method of producing a relief by sculpture or sculpture has a problem in that the production cost and time are increased because an extremely skilled worker or a craftsman manually performs the method. In addition, since the relief engraving machine uses a mechanical scanning method, there is a limitation that a line drawing pattern for expressing a relief shape is limited to straight lines.

In order to solve the problem caused by the manual work, a method of drawing a line drawing relief pattern by computer processing has been proposed today. As a known elementary algorithm by computer processing, for example, as disclosed in Japanese Patent Application Laid-Open No. 5-120450, a binary image composed of a picture area and a background area is stored in a computer in the form of raster data or contour data. The reference lines are defined on the binary image at predetermined intervals so as to be parallel to each other, and the inclination angle and the peak point are determined in advance as parameters that affect the three-dimensional appearance of the line drawing relief pattern. There is a method in which a parallel line is created based on a reference line, and the parallel line is formed so as to be bent at a boundary between a background portion and a picture portion of a binary image serving as a motif. In addition, Japanese Patent Application Laid-Open No. 5-158207
As disclosed in Japanese Unexamined Patent Application Publication, a gradation image composed of a set of pixels in which any one of density values 0 to 255 is defined is prepared in a computer, and a plurality of parallel images are arranged on this image at predetermined intervals. Define a reference line, binarize the input gradation image, extract the contour line that fits the image, and convert the pixels on the reference line into pixels in the internal area of the picture and pixels in the external area based on the contour line. For the pixels in the inner region, there is a method of defining a displacement point at each scale position of the density value and creating a line based on a reference line. Further, JP-A-5-15
As disclosed in JP-A-8208, JP-A-5-158209 and JP-A-5-158210, a line drawing relief pattern having a line drawing as a motif is prepared in a computer as digital data. Is defined, a line is created based on this baseline,
There has been proposed a method in which a line is formed so as to bend in the vicinity of the intersection with a line drawing to be a motif, or in the vicinity of the intersection by replacing a reference line with a detour line. However, in the computer processing method using the algorithm disclosed in the above publications, there is a problem that the transfer line group is limited to a straight line or a limited curve similarly to the mechanical method, and the relief pattern can only draw a simple rising curve.

[0004] More recently, the technology for generating a line drawing of a geometric function curve by computer processing has advanced, and the technology for creating a line drawing relief pattern can also be applied to a complicated geometric function curve line drawing of a motif pattern. Has become. As a result, in addition to the above-mentioned publication, there are some which are realized as computer software. For example, Barco Graphics (Belgium) has already commercialized and sold software having a line drawing relief pattern generation function. However, as shown in FIG. 2, the line drawing relief pattern that can be drawn by the software by the internal processing is the size of the boundary line at the rising edge of the line d of the line drawing relief pattern at the boundary line of the binary image A or the outline data. In addition to generating from the distance c outside b, the object line d of the relief line can be controlled only by the rising angle and circularity of the relief line. Although it can be used, there is a problem that only a simple rising curve can be drawn in the relief pattern.

As a method for solving the above-mentioned problem, when a line drawing relief pattern having a complicated shape is desired to be created, a gradation image of raster data consisting of a set of pixels having a density value of 0 to 255 called a template is defined. It can be realized by using. The method for generating a line drawing relief pattern using the template is described as follows.
55 is a method of converting a density value into relief height information from a gradation image composed of a set of pixels in which any one of 55 is defined. However, in the above-mentioned method using the template, for example, in the relief template creation software of Yura (Hungary), the binary image A shown in FIG. In this case, the rising shape of the relief is controlled by four types of dilation processing by converting the boundary line of the connected component of the binary image into a grayscale image as shown in FIG. The pattern A "is a line drawing relief pattern generated from the outside of the boundary line. Therefore, a template for creating a three-dimensional line drawing relief pattern with a fine and complex contour line cannot be obtained. Even after the pattern is formed, there is a problem that the line is flat and there is no intonation.

[0006]

Also, the three-dimensional data obtained by synthesizing them is three-dimensionally displayed as shown in the image c1 of the three-dimensional shape projection file in FIG. 13 and visually raised as shown in FIG. 15 created by the three-dimensional shape control file template c2 shown in FIG. The line drawing relief pattern c3 as described above can be created.

(Details of the three-dimensional data creation means 2) As shown in FIG. 16, the three-dimensional data creation means 2 shown in FIG. 1 calculates binary image data and continuous tone image data when calculating the height of three-dimensional data of the present invention. For data, contour data such as spline curves and Bezier curves are prepared on a computer memory in the form of raster data, and the data is sequentially processed for each data. Note that, in addition to the above data, an area for storing the processing result is prepared in advance on the computer memory. First, by processing F1 in FIG. 16, the heights h1 (x, y), h2 (x, y),... Hn (x,
and y) a data storage area. Next, a binary image data processing method or a contour line information data processing method is selected as a method for calculating the height of the stereoscopic data by selecting the input image F2. When the binary image data processing method is selected, a binary image represented in the form of raster data as shown in FIG. 20 is input to the computer memory by the processing of the binary image input F3. When the contour information data processing method is selected, control point information or vector information such as a spline curve, a Bezier curve, and a cubic function curve, for example, in a Bezier curve as shown in FIG. , Through the processing of the contour line information input F4. Further, using the contour information data, an interpolation point is generated by a known expansion formula corresponding to each curve, and this is raster-expanded on a computer memory to form a translocation pixel G2 as shown in FIG. . At this time, vector data,
Alternatively, interpolation points are prepared sufficiently densely so that outline pixels do not become discontinuous when rasterizing F5. Or, using binary image data expressed in the form of raster data on a computer memory input from the binary image input F3,
A contour pixel G2 can also be obtained from the binary image data by performing the contour extraction F6.

Next, when the binary image data processing is selected by the selection F2 of the input image in FIG. 16, the processing procedure by the image contraction method is executed as shown in FIG. (Image Shrinkage Method) The height of the background area of the input binary image as shown in FIG.
The process of setting pixel G = 0 (whitening) when gi = 0 (white) in the vicinity of pixel G using the contraction filter f near eight pixels (or near four pixels) shown in FIG. Are executed in the order of the raster directions indicated by arrows. Thereby, the contraction filter processing F7 of FIG.
For the binary image on the memory, FIG. 21 when k = 1, FIG. 22 when k = 2,
When k = 3, as shown in FIG. 23, the pattern is alternately and repeatedly applied until the picture portion of the original image, that is, the connected component G1 of the binary image disappears. At this time, the height h of the three-dimensional data determined by the function of the number of repetitions k is set at the contracted pixel position shown in FIG.
By securing f (k) in the computer memory at F8 in FIG. 18, a solid having contour lines reflecting the contour shape of the original image is displayed on the computer memory as shown in FIG. Be built. In this case, ridge lines may be generated depending on the contour shape of the original image. However, if necessary, they are removed by smoothing processing. If the function f (k) of the number of repetitions k is a univalent function of the number of repetitions k, a constant, a linear function, a higher-order function, a trigonometric function, an exponential function, an ellipse, a hyperbola, a parabolic quadratic curve function, Any of spline definition functions and the like may be used, and various three-dimensional representations can be constructed on a computer memory by using these functions. In the present invention, as shown in FIG.
For example, four types of three-dimensional expression methods were prepared as 9. FIG.
In the case where the convex ellipse three-dimensional representation method indicated by a in FIG. 8 is selected, a relief by a convex ellipse as shown in FIG.

(Equation 1) Is used. When the concave ellipse three-dimensional representation method shown as A in FIG. 18 is selected, the relief by the concave ellipse as shown in FIG. 27 is obtained, and the function

(Equation 2) Is used. Here, a and b are constants representing the major axis and the minor axis of the ellipse, respectively, and when k> a, f (k) = b. When the vertical three-dimensional representation method shown as c in FIG. 18 is selected, a vertical rising relief as shown in FIG. 28 is obtained, and the function

[Equation 3] Is used. In the case where the linear stereoscopic representation shown as d in FIG. 18 is selected, a linear startup relief as shown in FIG. 29 is obtained, and the function

(Equation 4) Is used. C is a constant. The function for obtaining the three-dimensional representation is not limited to the equations (1) to (4).

Next, the transit information data processing will be described. When the transit information data processing is selected by the selection F1 of the input image in FIG. 16, the processing procedure shown in FIG. 30 is executed. (Shortest distance calculation method) Normally, one point (one pixel) g inside a contour as shown in FIG. 31 is designated, and pixels adjacent to the designated pixel are successively filled in arithmetic processing using the contour pixel G2 as a distinguishing point. Thus, a picture portion is formed. Next, the distance L from the position of the pixel g (the pixel of the picture portion) inside each contour line G2 to each contour pixel position is determined, and the minimum value (shortest distance) r is calculated by the minimax method F10.
Then, the height F11 of the target pixel position is set to a function h = f (r
(X, y)). By applying this to all the pixels of the picture portion, a solid having contour lines as if the contour line of the original image was contracted inward in the normal direction image was constructed on the computer memory as shown in FIG. You. In this case, ridge lines may be generated depending on the contour shape of the original image. However, if necessary, they are removed by smoothing processing. The function f of the shortest distance r is the same as in the image shrinkage method.
(R (x, y)) may be any of a constant, a linear function, a higher-order function, a trigonometric function, an exponential function, an ellipse, a hyperbola, a parabolic quadratic curve function, a spline definition function, and the like. A three-dimensional shape can be constructed on the memory. Further, as in the image shrinking method, in the present invention, as shown in FIG. 30, for example, four types of expression methods are prepared as the selection F12 of the three-dimensional expression. When the following function shown as A in FIG. 30 is used, a relief by a convex ellipse as shown in FIG. 26 is obtained.

(Equation 5) When the following function shown as a in FIG. 30 is used,
A relief with a concave ellipse as shown in FIG. 27 is obtained.

(Equation 6) a and b are constants representing the major axis and minor axis of the bridge circle, and when r> a, f (r (x, y) = b. The following function shown as C in FIG. 30 was used. In this case, a vertical rising relief as shown in FIG. 28 is obtained.

(Equation 7) When the following function shown as D in FIG. 30 is used,
A linear start-up relief as shown in FIG. 29 is obtained.

(Equation 8) Here, C is a constant. The mathematical expressions for obtaining the three-dimensional expression are not limited to the mathematical expressions (5) to (8).

For example, based on a solid constructed on a computer memory from the gourd-shaped binary image shown in FIG. 33 by the algorithm used in the image shrinkage method or the shortest distance calculation method, as shown in FIG. Although a line drawing relief pattern is created, in the simple outline image as shown in this example,
A relief having a plurality of local maximum points (or local minimum points) in a state in which the outline information is reflected is obtained by an algorithm that connects both ends of the outline of the known binary image shown in FIG.
As shown in FIG. 4, since the maximum point becomes a uniform height, it cannot be realized.

(Details of the three-dimensional data synthesizing means 3) The three-dimensional data synthesizing means 3 shown in FIG. 1 is means for synthesizing a plurality of three-dimensional data created by the three-dimensional data creating means 2. The three-dimensional data combining means 3 will be described in detail with reference to FIG. Note that a smoothing process F13 is performed on the constructed three-dimensional data as needed. The three-dimensional data on the computer memory created by the three-dimensional data combining means (1) is combined by four arithmetic operations or logical operations. First, the height hs (x,
According to the present invention, at least the data storage area F14 of y) is provided, and the height of the synthesized stereoscopic data is obtained by at least seven types of synthesis methods. That is, any combination of the linear sum, the arithmetic product, the arithmetic quotient, the arithmetic average, the difference, the logical operation 1 (logical sum), the logical operation 2 (logical product), and the like may be performed by selecting the synthesis method F15. Various synthetic three-dimensional data can be constructed on the memory. The function for obtaining the synthesized three-dimensional data is not limited to this. For example, the stereoscopic data obtained from the first binary image is h1 (x, y), the stereoscopic data obtained from the second binary image is h2 (x, y), and the n-th stereoscopic data is hn ( x, y), and the synthesized solid data is hs
Assuming that (x, y), a. In the case of a function of a linear sum, the calculation is performed by the following equation (9). From the combined three-dimensional data obtained in this way, the resulting line drawing relief pattern is a line drawing relief pattern c4 shown in FIG.

(Equation 9) B) When the arithmetic product function is selected, for example, the following equation (1
0).

(Equation 10) (C) When an arithmetic quotient function is selected, synthesis is performed using the following equation (11).

[Equation 11] D) When the function of arithmetic mean is selected, the following formula (12)
