DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings.

  A seal manufacturing system 1 according to this embodiment includes an image processing apparatus 100 and a seal manufacturing apparatus 200 as shown in FIG. The seal manufacturing system 1 determines a shape (hereinafter referred to as a cutout shape) in which the image processing apparatus 100 cuts out the seal, and manufactures a seal with the seal manufacturing apparatus 200 based on the determined cutout shape. Here, the image processing apparatus 100 determines whether or not the seal having the determined shape is sufficiently easy to handle. If the image processing apparatus 100 determines that the seal is not sufficiently easy to handle, the image processing apparatus 100 forms a cutout shape so as to be a sufficiently easy to handle shape. Correct it.

  Note that whether or not the seal is sufficiently easy to handle is determined based on whether or not the seal has a sufficiently wide width. Specifically, if the seal has a portion whose width is narrower than a predetermined threshold, it cannot be said that it is sufficiently easy to handle. For example, since such a narrow portion does not have sufficient strength, it is easy to break or break at the portion. For this reason, although a predetermined threshold value changes with kinds of seal, those skilled in the art can determine an optimal threshold value by experiment.

Next, the hardware configuration of the image processing apparatus 100 constituting the seal manufacturing system 1 will be described.
The image processing apparatus 100 includes a personal computer, and includes a control device 100a, a temporary storage device 100b, an external storage device 100c, an image output device 100d, an input device 100e, and a display device 100f as shown in FIG.

  The control device 100a is, for example, a CPU (Central Processing Unit), and performs overall control of the image processing device 100 by executing software processing according to a program stored in the external storage device 100c. The temporary storage device 100b is, for example, a DRAM (Dynamic Random Access Memory), and temporarily stores information (data) to be processed when the control device 100a executes a program. The external storage device 100c is, for example, a hard disk drive, and stores a file representing an image, a file representing an image area which is one area of the image, or a setting file representing various settings.

  The image output device 100d is, for example, a communication card, and outputs an image file to the seal manufacturing device 200 by communication. The input device 100e is, for example, a keyboard, and the display device 100f is, for example, a liquid crystal display (LCD). The input device 100e and the display device 100f provide a user interface.

Next, software processing executed by the image processing apparatus 100 using the hardware illustrated in FIG. 1B will be described.
The control apparatus 100a of FIG.1 (b) performs the cutting data production | generation process which produces | generates the cutting data showing a cutting shape as shown in FIG. In addition, the control device 100a includes an image acquisition unit 111, a cutout data acquisition unit 112, a margin setting unit 130, an area reduction unit 140, a division determination unit 150, a margin resetting unit 160, and an area enlargement unit 170 illustrated in FIG. The image cutout unit 180, the cutout image storage unit 191, and the cutout data confirmation storage unit 196 perform the following processing, and the temporary storage device 100b functions as the setting storage unit 120.

  When the image processing apparatus 100 starts the cutout information generation process, the image acquisition unit 111 in FIG. 3A acquires image data representing an image from the external storage device 100c (step S01). Note that the image acquisition unit 111 may download image data from the Internet.

  Next, the cutout data acquisition unit 112 in FIG. 3A acquires cutout data representing a shape (that is, a cutout shape) and a position to cut out the image represented by the image data acquired by the image acquisition unit 111. This is because the image area printed on the sticker is obtained from the image data. Specifically, the cutout data acquisition unit 112 acquires mask data for masking a region that is not cut out from the image represented by the image data from the external storage device 100c. Here, when the image represented by the image data is an image representing a swan as shown in FIG. 4A and the image area representing the swan is cut out as an image area to be printed, the cut-out data acquisition is performed. The unit 112 acquires mask data representing a white image area having a swan shape as shown in FIG. 4B and a black background image area from the external storage device 100c. In general, white is represented by data having a value of 1 for all bits, and black is represented by data having a value of 0. Therefore, white is obtained by performing an AND operation on a bit string constituting mask data and a bit string constituting image data. This is because data representing an area corresponding to the shape and position of the area is cut out from the image data. Note that after the mask data is acquired, the cutout data acquisition unit 112 inverts the brightness of the mask data. This is for generating data representing in black the image area cut out from the image represented by the image data (hereinafter referred to as the cutout area) as shown in FIG. Note that the cutout data acquisition unit 112 may generate mask data based on, for example, an operation of the input device 100e by the user. According to this configuration, an arbitrary image area can be cut out.

  After executing step S02 in FIG. 2, the margin setting unit 130 in FIG. 3A reads a clipping margin that is a predetermined threshold value from the setting storage unit 120 (step S03). Next, the margin setting unit 130 initializes the value of the mask offset indicating the amount by which the width of the cutout area is increased with the value of the cutout margin (step S04).

  Next, the area reduction unit 140 executes a minus offset process for reducing the cutout area (step S05). As shown in FIG. 3B, the area reduction unit 140 includes a first format conversion unit 146, a contour line width setting unit 147, a contour line color setting unit 148, and a second format conversion unit 149. .

Here, the minus offset process of step S05 executed by the area reduction unit 140 will be described. The process of step S05 is a process as shown in FIG.
First, the first format conversion unit 146 of FIG. 3B constituting the region reduction unit 140 traces the cutout data and converts it into SVG (Scalable Vector Graphics) format data (step S21). Specifically, the first format conversion unit 146 converts the cut-out data represented in the bitmap format into data in the SVG format as shown in FIG. The data converted into the SVG format is composed of a path tag area surrounded by path tags and a G tag area surrounded by G tags. The path tag area is an area in which path data representing a path representing one continuous area (that is, not divided) is stored. The path data represents the shape and position of the continuous area with one or more coordinate values and commands. The G tag area is an area in which one or more pass tag areas are grouped, and data for determining the presence / absence, width, and color of the outline of the area represented by the grouped pass tag areas is stored. Specifically, as shown in FIG. 6, the G tag region described as “stroke: none” sets the outline of the cutout region to “none”.

  After executing step S21 in FIG. 5A, the area reduction unit 140 in FIG. 3B sets a display line (hereinafter referred to as a stroke) representing the outline of the cutout area to “present (valid)”. (Step S22). The outline of the cutout area is a conceptual line that represents the boundary between the cutout area and the background area, and does not have a line width. On the other hand, the stroke is a line that traces the outline, and has a line width that is changed by setting.

Next, the contour line width setting unit 147 sets the stroke thickness to the cutout margin read in step S03 of FIG. 2 (step S23). Specifically, the contour line width setting unit 147 rewrites a part of the G tag area constituting the cutout data to the description “stroke-width: 131.28205872” as shown in FIG. The cutout area represented by the data in which the G tag area is rewritten has a stroke having a thickness of a set value (that is, the value of the cutout margin “131.28205872”) as shown in FIG. In FIG. 7B, for the convenience of drawing, the stroke color is represented by black different from the actually set white, and the color of the cutout region is represented by white different from the actual black.
Next, the outline color setting unit 148 sets the stroke color of the cutout region to the same white color as the background color (step S24).

  Here, when the contour line width setting unit 147 sets the thickness of the stroke to the value of the trimming margin, the stroke width is set to the margin of the trimming margin on both the inside and outside of the cropped image with reference to the contour line represented by the stroke. Enlarge each by half of the value. When the outline color setting unit 148 sets the stroke color as the background color of the cutout area, the outline area from the outline of the cutout area to the inside by half of the value of the cutout margin (that is, the area represented by the cutout area and the stroke) (The area where and overlap) becomes the same color as the background. For this reason, the cutout area is reduced to a reduced area in which the outline area is removed from the cutout area, as shown in FIG. According to this configuration, the contour area of the image area can be easily removed from the image area.

  After executing step S24 of FIG. 5A, the second format converter 149 of FIG. 3B converts the path data representing the reduced area into bitmap format data (step S25). Thereafter, the area reduction unit 140 ends the execution of the minus offset process.

  2, after the region reduction unit 140 completes the minus offset process, the division determination unit 150 in FIG. 3A performs the bitmap format data generated in step S25 in FIG. The path trace is performed (step S06). Path tracing refers to converting bitmap format data into SVG format data (hereinafter referred to as trace data) in which the image area is represented by path data by tracing the bitmap format data representing the image area. .

  Next, the division determination unit 150 counts the number of paths that the trace data has (that is, the number of path data) (step S07). Here, the reduced region shown in FIG. 7C is divided into two continuous regions at a portion narrower than the cutout margin (that is, the base portion of the swan's neck) as a result of removing the contour region. . These two continuous areas are represented by trace data having two paths (that is, path tag areas) as shown in FIG. This is because one continuous area is usually represented by one path.

  Next, the division determination unit 150 determines whether or not the region has been divided as a result of removing the contour region from the cutout region. Specifically, the division determination unit 150 determines whether or not the number of paths included in the trace data is larger than the number of paths before the cutout area is reduced. That is, since the number of paths before the cutout area is reduced is the value “1”, the control device 100a determines whether or not the number of paths included in the trace data is greater than or equal to the value “2” (step S08). ). According to this configuration, it can be easily determined whether or not the cutout region has a portion thinner than a predetermined threshold value. In particular, since the number of continuous regions constituting the cutout region before and after the removal of the contour region is determined by the number of passes, it can be more easily determined whether or not the cutout region has a portion thinner than a predetermined threshold value. As a specific example, for all points on the outline of the cutout region, the distance to the nearest other point is calculated, and it is determined whether or not all the calculated distances are longer than a predetermined threshold. In comparison, it can be easily determined whether or not the cutout region has a portion whose width is narrower than a predetermined threshold.

  In step S08, when the division determination unit 150 determines that the number of passes is greater than or equal to the value “2” (step S08; Yes), the margin resetting unit 160 further increases the mask offset by the cutout margin. The value is reset (step S09).

  Next, the area enlarging unit 170 executes a plus offset process for enlarging the cutout area generated from the mask data (step S10). As shown in FIG. 3C, the region enlargement unit 170 includes a cutout information generation unit 171, a first format conversion unit 176, a contour line width setting unit 177, a contour line color setting unit 178, and a second format conversion. Part 179.

Here, the plus offset process of step S10 executed by the area enlargement unit 170 will be described. The process of step S10 is a process as shown in FIG.
First, the cutout information generation unit 171 in FIG. 3C constituting the region enlargement unit 170 acquires cutout data in the same manner as the process in step S02 in FIG. 2 (step S31). Next, the first format conversion unit 176 converts the cutout data acquired in step S31 into SVG data (step S32), similarly to step S21 in FIG.

  Next, similarly to step S22, the region enlargement unit 170 validates the stroke of the cutout region represented by the SVG data acquired in step S32 (step S33). After that, the contour line width setting unit 177 sets the stroke thickness to the mask offset, similarly to step S23 (step S34). Next, unlike step S24, the outline color setting unit 178 sets the stroke color to the same black as the color of the cutout region (step S35).

  That is, in steps S34 and S35, when the outline width setting unit 177 sets the stroke thickness to be thicker than before setting and the outline color setting unit 178 sets the stroke to the same color as the cutout region, the stroke and The cutout area is integrated with the appearance. For this reason, an area represented by a stroke is added to the cutout area, and the position of the outline of the cutout area moves outward. Therefore, the cutout region shown in FIG. 4C is corrected to an enlarged region wider than the mask offset as shown in FIG. 9A. According to this configuration, when the image region has a portion thinner than the predetermined threshold, the portion can be corrected to be thick. Further, according to this configuration, the image area can be easily enlarged by setting the width and color of the contour line.

  After executing the process of step S35 of FIG. 5B, the second format conversion unit 179 of FIG. 3C converts the path data representing the enlarged cut-out area into bitmap format data as in step S25. (Step S36). Next, the area enlargement unit 170 sets the data obtained by converting the pass data into a bitmap as cut data (step S37). Thereafter, the area enlargement unit 170 ends the execution of the plus offset process.

  In step S10 in FIG. 2, after the region enlargement unit 170 in FIG. 3A completes the plus offset process, the region reduction unit 140 performs a minus offset process on the enlarged region (step S05). That is, the area reduction unit 140 removes the outline area of the enlarged area from the enlarged area.

Next, the division determination unit 150 performs the above-described processing from steps S06 to S08 on the enlarged region reduced by the minus offset processing (steps S06 to S08).
Here, the enlarged region from which the contour portion has been removed by the minus offset processing is a region composed of one continuous region as shown in FIG. For this reason, the division determination unit 150 determines that the number of paths representing the enlarged region from which the outline portion has been removed is the value “1” and does not exceed the value “2” (step S08; No).

  Next, the cutout data confirmation storage unit 196 in FIG. 3A confirms the cutout data representing the enlarged region as a region representing the shape of the seal, and stores the confirmed cutout data in the external storage device 100c to manufacture the seal. It outputs to the apparatus 200 (step S11). Next, the image cutout unit 180 cuts out the image area corresponding to the white area of the mask data from the image represented by the image data, and obtains a cutout image as shown in FIG. 9C (step S12). . Thereafter, the cut-out image storage unit 191 stores cut-out image data representing the cut-out image in the external storage device 100c and outputs the cut-out image data to the seal manufacturing apparatus 200 (step S13). Thereafter, the image processing apparatus 100 ends the execution of the process.

  Note that the seal manufacturing apparatus 200 manufactures a seal having the shape of the enlarged region represented by the cut data based on the cut data output by the image processing apparatus 100 in step S11. In addition, the sticker manufacturing apparatus 200 prints the cutout image represented by the cutout image data output from the image processing apparatus 100 in step S13 on the sticker having the shape of the enlarged region. Here, since the width of the shape of the seal represented by the cutout data is corrected by a cutout margin wider than the shape of the cutout image, the seal manufactured by the seal manufacturing apparatus 200 is as shown in FIG. A margin (margin) is provided from the edge of the sticker to the portion where the cut-out image is printed. According to this configuration, before manufacturing the seal, not only can it be easily determined whether the manufactured seal has a portion thinner than a predetermined one, but the portion can be corrected thickly based on the determination result. Accordingly, a seal that is easy to handle because it is difficult to break and difficult to cut can be manufactured.

  In the present embodiment, the area enlarging unit 170 has been described as enlarging the image area by changing the width and color of the stroke representing the outline of the image area. However, the present invention is not limited to this. For example, the area enlarging unit 170 can employ a configuration in which the size of the image area is directly enlarged by a predetermined ratio in the vertical direction (scanning direction) and the horizontal direction (sub-scanning direction). Further, for example, the region enlarging unit 170 can adopt a configuration in which the image region is expanded by changing pixels outside the outline of the image region by a predetermined pixel value to the color of the pixels constituting the image region.

  Similarly, the area reduction unit 140 has been described as reducing the image area by changing the width and color of the stroke representing the outline of the image area, but the present invention is not limited to this. The reduction method used by the region reduction unit 140 may be a reduction method that divides an image region at a portion thinner than a predetermined value by reduction. For example, the area reduction unit 140 can employ a configuration in which the size of the image area is directly reduced by a predetermined ratio in the vertical direction (scanning direction) and the horizontal direction (sub-scanning direction). In addition, for example, the region reduction unit 140 can adopt a configuration in which the image region is reduced by changing pixels inside the image region by a predetermined value to the color of the pixels forming the background region. Further, for example, the area reduction unit 140 directly reduces the size of the image area by a predetermined ratio in the vertical direction (scanning direction) and the horizontal direction (sub-scanning direction), and then reduces the outline of the reduced image area. From this, it is possible to adopt a configuration in which a pixel that is inside by a predetermined pixel value is changed to the color of the pixel that forms the background region.

  In addition, not only can an image processing communication apparatus provided with a configuration for realizing the functions according to the present invention be provided in advance, but also an existing image processing apparatus can be made to function as the image processing apparatus according to the present invention by applying a program. it can. That is, by applying an image processing program for realizing each functional configuration by the image processing apparatus 100 exemplified in the above embodiment so that a computer (such as a CPU) that controls the existing image processing apparatus can be executed. It can function as the image processing apparatus 100 according to the invention.

  The distribution method of such a program is arbitrary. For example, the program can be distributed by being stored in a recording medium such as a memory card, a CD-ROM, or a DVD-ROM, or can be distributed via a communication medium such as the Internet.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications, within the scope of the gist of the present invention described in the claims, It can be changed.
