DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. Prior to the description of the embodiments, a brush eye according to the present invention is necessary for understanding the following description. The basic concept of the method of creating the tone hairline pattern will be described.

For example, consider a scar formed when a smooth surface is rubbed only once with a brush. As shown in FIG. 1, the scar has a relatively uniform orientation, position, and center angle. It can be considered that a plurality of arcs are arranged. This is a pattern called a brush tone. Each arc can be considered a hairline. Therefore, in this specification, as shown in FIG.
A pattern in which a plurality of hairlines having relatively uniform orientation, position, and central angle are arranged is referred to as a block pattern. In addition, as described below, in this embodiment, the length, radius, and central angle of each hairline constituting one block pattern are different,
All hairlines are arranged concentrically. Therefore, a large number of block patterns are created, and these block patterns are arranged at appropriate positions in the created image at appropriate angles. In other words, each block pattern can be regarded as a part for creating a brush-tone hairline pattern.

FIG. 2 is a diagram partially showing an example in which a plurality of block patterns are arranged on a created image in this manner. By such processing, a brush-like tone hairline pattern as shown in FIG. 9 is created. The position and angle of each block pattern on the created image and the method of determining the position and angle will be described later. Further, as shown in FIG. 2, when arranging a block pattern on a created image, overlapping of hairlines of block patterns arranged at adjacent positions is allowed.

FIG. 3 shows an embodiment of a brush-like hairline pattern creating apparatus according to the present invention. 3, reference numeral 1 denotes an input unit, 2 denotes an arrangement position determining unit, 3 denotes a block pattern creating unit, 4 denotes a block pattern arranging unit, and 5 denotes a raster image processor (RIP).

The brush-tone hairline pattern creating apparatus shown in FIG. 3 can be constituted by a computer system. That is, the input means 1 is an input device including a keyboard and a pointing device, a control device including a CPU, and a GUI (Graphical User Int) using a monitor.
erface), and arrangement position determining means 2,
The block pattern creating unit 3 and the block pattern arranging unit 4 can be configured by installing software for performing processing described below in the control device. Also, R
For the IP5, a general RIP can be used. However, in order to generate a smooth curve by spline interpolation based on data expressed in a vector format as described later and convert it into raster data, the IP5 is particularly required. It is desirable to use the RIP disclosed in Japanese Patent Application Laid-Open No. 2000-57358 previously proposed by the applicant.

[Outline of Each Component] First, an outline of each component of the component shown in FIG. 3 will be described.

(1) Input Means 1 The input means 1 is for inputting values of various parameters for creating a brush-tone hairline pattern. Here, at least the values of the following parameters are input. • Created image size (x-direction size: xsize, y-direction size: ysize) • Number of block patterns (nb) • Number of hairlines in block patterns (maximum value nhlmax)
, Minimum value nhlmin) Hairline interval in block pattern (maximum value dma
x, minimum value dmin) Hairline radius (maximum value rmax, minimum value rmin) Hairline length (maximum value lhlmax, minimum value lhlmi)
n)

The meanings of these parameters are as follows. The created image size is the size of the brush-tone hairline pattern to be created, and its size x in the x direction.
Enter the value of size and the value of size ysize in the y direction. In the following description, as shown in FIG.
The position in the area of the created image is the origin O at the lower left corner of the created image.
The horizontal direction is represented by an x-axis, and the vertical direction is represented by an orthogonal coordinate system having a y-axis.

The number of block patterns is a parameter for determining the number of block patterns to be arranged on the created image, and the number nb is input. In this embodiment, the number of block patterns is input. However, the density ρ (unit: pieces / mm ² ) for arranging the block patterns is input, and xsize and ysize are expressed in units of mm, and nb = [ ρ × xsize × ysize] (1) The number nb of block patterns to be arranged on the created image may be obtained. In equation (1), [] indicates a Gaussian symbol. That is, [a] is the largest integer not exceeding a.

The number of hairlines in a block pattern is a parameter for determining the number of hairlines arranged in one block pattern, and a maximum value nhlmax and a minimum value nhlmin of the number are input.

The hairline interval in the block pattern is
It is a parameter for determining the interval between adjacent hairlines in a plurality of hairlines arranged in one block pattern, and its maximum value dmax and minimum value dmi
Enter n. In the following, the first hairline from the innermost hairline, the second hairline,..., And the interval between the kth hairline and the (k + 1) th hairline are referred to as the kth interval. Then, let the k-th interval be dk.

The hairline radius is a parameter for determining the radius of each hairline arranged in the block pattern, and has a maximum value rmax and a minimum value rmi.
Enter n.

The hairline length is a parameter for determining the length of each hairline arranged in the block pattern, and its maximum value lhlmax and minimum value lhlmin are input. Parameters other than the above parameters will be described each time.

(2) Arrangement Position Determining Means 2 Arrangement position deciding means 2 converts a block pattern created by a block pattern creating means 3 to be described later into any position on the created image based on the parameters input by input means 1. At what angle, where to place it,
And an arrangement angle at each arrangement position. Then, the arrangement position determining means 2 assigns a serial number to the determined arrangement position in the order of coordinate values, and notifies the block pattern arrangement means 4 of the coordinates of the determined arrangement position and the arrangement angle at each arrangement position. Note that the serial numbers may be assigned in any order in the order of the coordinate values. For example, the serial numbers may be assigned in ascending order of the y coordinate values of the arrangement positions and in ascending order of the x coordinate values.

(3) Block Pattern Creation Means 3 The block pattern creation means 3 creates nb block patterns based on the parameters input by the input means 1. There are various methods for expressing each created hairline. For example, a block pattern can be represented by raster data, or an arc representing a hairline can be represented by a mathematical expression.
The block pattern creating means 3 defines a predetermined number of control points on the generated hairline, and expresses the control points with the coordinates of the control points. That is, one hairline is expressed in a vector format including a coordinate value sequence of a predetermined number of control points. Then, the block pattern creating means 3
Assigns serial numbers from 1 to nb to the created block patterns in an appropriate order, for example, in the order of creation, and notifies the block pattern arranging unit 4 of the numbers. The data structure of each block pattern at this time is as shown in FIG. 5, for example. FIG. 5 shows an example of vector-format data for the k-th block pattern, and it is assumed that n hairlines are arranged in the block pattern. This data describes that there are m control points on each hairline, and further writes the coordinate values of the m control points taken on each hairline. However, as will be described later, the coordinate value of the control point of each hairline of each block pattern created by the block pattern creation means 3 is not a coordinate value on the created image but a relative value with the virtual center position of each block pattern as the origin. Coordinate values.

(4) Block pattern arranging means 4 The block pattern arranging means 4 is notified from the block pattern creating means 3 to the arrangement position notified by the arrangement position deciding means 2 at the arrangement angle designated to the arrangement position. These block patterns are allocated and arranged by associating the numbers of the arrangement positions with the numbers of the block patterns. What is actually performed is the process of converting the coordinate values of each control point. This will be described later.

(5) RIP5 The data of the brush-like hairline pattern is completed by the processing of the block pattern arranging means 4. In this embodiment, since the data is expressed in the vector format, a printing plate is prepared. In order to create an embossed plate, it is necessary to convert it to a raster image. Therefore R
IP5 is provided. RIP5 is not the essence of the present invention, and a general RIP can be used as long as it can develop a raster image based on vector format data. In particular, RIP5 is disclosed in Japanese Patent Application Laid-Open No. 2000-57358. It is desirable to use an existing RIP.
RI disclosed in JP-A-2000-57358
If P is used, not only can data in vector format be developed into a raster image, but also additional expressions such as width can be provided.

[Explanation of Operation] Next, the operation of the brush-tone hairline pattern forming apparatus shown in FIG. 3 will be described. First,
The operator inputs at least the above parameter values through the input means 1. The parameter value input from the input unit 1 is notified to the arrangement position determining unit 2 and the block pattern creating unit 3. When receiving the parameter values from the input unit 1, the arrangement position determination unit 2 starts the arrangement position determination process, and the block pattern creation unit 3 starts the block pattern creation process.

(1) Operation of Arrangement Position Determination Means 2 First, the arrangement position determination processing in the arrangement position determination means 2 is as follows. The arrangement position determining means 2 determines nb positions (arrangement positions) (cx, cy) at which the specified nb block patterns are to be arranged, and an angle at which the block pattern is arranged at each arrangement position. Determine the arrangement angle φ. The coordinate value of the arrangement position determined here is a coordinate value on the created image.

There are the following two methods for determining the arrangement position, and either method may be used. One method is to specify the specified created image size xsize, ysize
And a random number, and in this method, k
The x-coordinate value cxk and the y-coordinate value cyk of the second arrangement position are obtained by the following equations. cxk = xsize × RND (2) cyk = ysize × RND (3) Here, RND is a random number uniformly distributed in a range of 0 to 1. This is the same in the following.

However, in this method, since the arrangement positions are determined at random, the arrangement positions may be uneven in the created image. Another method is to avoid such unevenness in the arrangement position.
The nb arrangement positions are provisionally arranged in a regular grid pattern on the created image, and then the arrangement positions are slightly shifted in the x and / or y directions within a certain range using random numbers. According to this method, there is no regular unnaturalness in the arrangement position,
In addition, it is possible to prevent the arrangement position from becoming uneven on the created image.

The arrangement position determining means 2 determines the arrangement angle φk at the k-th arrangement position by the following equation. φk = 2π × RND (4) Since the arrangement angles are distributed in the range of 0 to 2π (rad) in equation (4), there is no restriction on the arrangement angles, but it is desirable to restrict the arrangement angles. In this case, the value of 2π in Expression (4) may be set to an arbitrary angle to be restricted. For example, the arrangement angle is 0 to π
When it is desired to limit the arrangement angle to within the range of (rad), the arrangement angle may be determined by φk = π × RND (5). Thus, the arrangement angle may be limited.

When the nb arrangement positions and the arrangement angles at each arrangement position are determined in this way, the arrangement position determining means 2 assigns the determined arrangement position and the arrangement angle as one set, assigns a serial number, Pattern arranging means 4
Notify. How to assign serial numbers is as described above.

(2) Operation of Block Pattern Creation Unit 3 The block pattern creation unit 3 creates the specified nb block patterns based on the input parameter values. First, a method of creating a block pattern will be conceptually described. When creating a certain block pattern, it is determined how many hairlines are to be arranged in the block pattern and what the length and radius of each hairline are.

The number nhl of hairlines to be arranged is determined by the following equation. nhl = nhlmin + RND × (nhlmax−nhlmin) (6) The length lhl of each of the nhl hairlines is determined by the following equation. lhl = lhlmin + RND.times. (lhlmax-lhlmin) (7) Further, the radius r1 of the first hairline is determined by r1 = rmin + RND.times. (rmax-rmin) (8).

As described above, the block pattern is created by arranging a plurality of hairlines, that is, circular arcs concentrically. The block pattern creating means 3 generates the distance dk between the kth hairline and the (k + 1) th hairline. Is determined by the following equation. dk = dmin + RND.times. (dmax-dmin) (9) Then, the radius ri of the i-th (i = 2,3,..., nhl) hairline from the second hairline onward is defined as ri = r1 + .SIGMA.d (10) Σd is the sum of d1 to d (i-1). Therefore, the radius of the second hairline is r2 = r1 + d1, and the radius of the third hairline is r3 = r1 + d1 + d2.
It is. The same applies to the radii of the fourth and subsequent hairlines.

Therefore, the center angle of the arc required to create each hairline is uniquely determined from the length lhlk and radius r of each hairline. lh length of kth hairline
If lk and the radius are rk, the central angle θk is as follows: θk = lhlk / rk (11)

From the above values, each hairline can be created. Here, a virtual origin O 'is set at an appropriate position, and as shown in FIG. An orthogonal coordinate system in which the horizontal direction is the x axis and the vertical direction is the y axis is defined. Then, a hairline is created symmetrically with respect to the x-axis or the y-axis about the virtual origin O '. Here, assuming that the hairline is created symmetrically with respect to the y-axis, the k-th hairline of the block pattern is shown in FIG.
The result is as shown in FIG. As is clear from the above description, it is clear that the hairline numbers are the first, second,... From the closest to the virtual origin O '. In FIG. 6B, the length of the hairline is lh
lk, the radius is rk, and the central angle is .theta.k, which are determined as described above.

Then, control points are set on the hairline. The number of control points may be registered in the block pattern creating means 3 in advance, or may be input from the input means 1 as a parameter. Here, it is assumed that the number of control points is ncp.

For setting control points on the hairline,
The first control point is taken at one end of the hairline, and the remaining (ncp-1) control points are taken from there toward the other end. Here, the first control point is taken at the position where the x-coordinate value of the hairline is the maximum, that is, in the case of FIG.
In the case of (b), the control points are sequentially set to the left, such as the second control point and the third control point.
Therefore, the central angle between two adjacent control points on the hairline is θ / (ncp−1). Therefore, x of each control point
The coordinate value and the y coordinate value can be easily determined geometrically, and the x coordinate value xkj and the y coordinate value of the jth control point of the kth hairline are ykj, respectively, as follows. xkj = rk × cos {θk / 2− (j−1) × θk / (ncp−1)} (12) ykj = rk × sinjθk / 2− (j−1) × θk / (ncp−1) )｝ (13) where rk is the radius of the k-th hairline, and θk is the central angle of the k-th hairline.

Thus, n on the k-th hairline
Vector-format data consisting of a sequence of coordinate values of cp control points is obtained. Note that the coordinate values of these control points are orthogonal coordinate values defined with respect to the virtual origin O ', and have nothing to do with the coordinate values on the created image. Therefore, the coordinate values of the control points at this point can be called virtual coordinate values.

When the above processing is performed on all the hairlines of the block pattern, vector format data as shown in FIG. 5 is obtained for the block pattern.

When data in vector format is obtained for one block pattern, the block pattern creating means 3 then moves the position of the virtual origin O 'to the approximate center position of the hairline group arranged in the block pattern. Translate to This is because, as described later, when the block pattern is allocated to the corresponding position on the created image determined by the position determining means 2, the position of the block pattern coincides with the position. It is of course possible to arrange the virtual origin O 'so as to match the corresponding arrangement position, but if the radius of the hairline is large, the hairline is separated from the arrangement position. This is not desirable. Therefore, the virtual origin is moved to a position where the hairlines are dense in the block pattern.

The position of the destination of the virtual origin need not be exactly the center of the hairline group arranged in the block pattern. Therefore, for example, when the number of hairlines is an odd number, the middle hairline, that is, the hairline is (2 m−
1) In the case of the number of hairlines (where m is a natural number), it is moved to the position on the y-axis of the m-th hairline to set a new virtual origin O ″, and when the number of hairlines is even 2m, (m-1) What is necessary is just to move to the position on the y-axis of the or the (m + 1) -th hairline and set it as a new virtual origin O ″. Accordingly, when a certain block pattern is composed of three hairlines as shown in FIG. 7, the middle hairline 2
The position on the y-axis of the hairline is set to the new virtual origin O ″
And

By this processing, the coordinate value of the control point on the hairline constituting the block pattern is not changed in the x coordinate value, and the y coordinate value is ykj = rk × sin, where 移動 is the movement amount of the virtual origin. {Θk / 2− (j−1) × θk / (ncp−1)} − △ (14)

By performing the above processing for all the block patterns, the coordinate values of the control points on each hairline can be determined for all the block patterns.

It should be noted that the coordinate values of the control points can be determined by the equations (12) and (14). However, when a raster image is formed based on the coordinate value sequence of the control points determined as described above, Since the centers of the individual hairlines in the block pattern are arranged on a straight line, an unnatural impression may be given. Therefore, by giving a fluctuation to the control point and giving the hairline an appropriate phase difference, it is possible to avoid the above-mentioned unnatural impression. For this purpose, for example, the coordinate values of the control points may be fluctuated by the following equation. xkj = rk × cos ｛θk / 2- (j-1) × θk / (ncp-1) + ψ｝ (15) ykj = rk × sin ｛θk / 2- (j-1) × θk / (ncp- 1) + ψ｝ − △ (16) Here, ψ is a function that takes a value in a predetermined angle range by a random number. The process of giving the coordinate values of the control points fluctuation is not indispensable, and may be performed as needed.

Although the process of creating a block pattern has been conceptually described above, as can be easily understood from the above description, the block pattern creating means 3 actually arranges the block pattern into the block pattern according to the equation (6). The number of hairlines nhl to be determined is determined, the length lhl of each hairline is determined by equation (7), the radius r of each hairline is determined by equations (8) to (10), and each hairline is determined by equation (11). Is determined for all the block patterns, and the process of obtaining the coordinate value of each control point of each hairline by the equations (12) and (14) is executed. In addition, in the case where the coordinate value of the control point has fluctuation,
The calculations of the equations (15) and (16) are performed.

As described above, when the vector format data is created for all the block patterns, the block pattern creating unit 3 passes the data to the block pattern arranging unit 4.

In the above description, the hairline in the block pattern is created symmetrically with respect to the y-axis of the orthogonal coordinate system centered on the virtual origin O ', but may be created symmetrically with respect to the x-axis. It is possible, and in that case, the coordinate value of each control point can be easily obtained geometrically.

(4) Operation of the block pattern arranging means 4 The block pattern arranging means 4 sets the position of each block pattern received from the arrangement position deciding means 2 at an angle designated by the arrangement position. Then, a process of allocating and arranging the vector format data for each block pattern received from 3 in association with the numbers is performed. As we will see later, this process is
This is nothing but a coordinate transformation for the coordinate values of the control points.

Now, assume that the k-th block pattern is arranged at the k-th arrangement position. The coordinate value of the k-th arrangement position, that is, the coordinate position on the created image is (cxk
, Cyk), and the arrangement angle at the arrangement position is φk.

The block pattern arranging means 4 first performs a process of rotating the coordinate values of all the control points for the k-th block pattern by the arrangement angle θk about the virtual origin O ″. Is, as is well known, the rotation angle θk with respect to the coordinate value (xkj, ykj) of each control point.
By applying a matrix of 2 rows and 2 columns determined by FIG. 8 is a diagram showing the concept.
FIG. 8B shows a state in which the block pattern shown in FIG. 8A is rotated by an angle θk about a virtual origin O ″ as shown in FIG. 8B.

When the rotation processing is performed in this way, the block pattern arranging means 4 next sets the virtual origin O ″ of the object subjected to the rotation processing to the coordinate value of the arrangement position (cxk, cyk). Is performed by adding cxk to the x-coordinate value of each control point, and adding cyk to the y-coordinate value.
Can be performed by adding Therefore, the original coordinate value of the control point is (xkj, ykj), and the coordinate value obtained by rotating the control point by the arrangement angle θk is (x′kj, y′k).
j), the final coordinate value of the control point obtained by the subsequent translation is (x'kj + cxk, y'kj +
cyk). Thus, the coordinate values of the control points correspond to the coordinate values on the created image. That is, the virtual origin O ″ of the block pattern is matched with the arrangement position,
It will be allocated and arranged on the created image.

The block pattern arranging means 4 executes the above processing for all arrangement positions. As a result, all the block patterns are arranged at the arrangement positions determined on the created image at the designated arrangement angle.

By the above processing, data of the brush-like tone hairline pattern is created. Then, if it is desired to form a raster image, the data of the brush-like tone hairline pattern created by the block pattern arranging means 4 may be given to the RIP 5. As described above, R
IP5 is not the essence of the present invention.
Since a known one disclosed in Japanese Patent Application Laid-Open No. 000-57358 may be used, the description is omitted.

As described above, according to the method and apparatus for creating a brush-like tone hairline pattern, a brush-like tone hairline pattern can be automatically created only by inputting a predetermined parameter value. In addition, the design with variations can be easily performed by inputting parameter values.
