Description

This disclosure relates to an information processing method.

Conventionally, for image data such as CAD (Computer Aided Design), a color or other specification is made for each constituent surface (face) of a component represented by an image in the image data, and then plate thickness or other specifications are specified according to the color specified for each constituent surface, thereby creating instructions for design and analysis.

However, with conventional technology, the user had to perform coloring processing on each of the multiple constituent surfaces of various shapes and sizes that make up a component, making it difficult to easily color components according to their surfaces.

The problem that this disclosure aims to solve is to provide an information processing method that can easily achieve coloring according to the constituent surfaces.

The information processing method according to the present disclosure includes a divided face information generation step of generating divided face information for each constituent surface of a member represented by an image of image data, in which the same first identification information is set for pixels constituting the same constituent surface, and the divided face information generation step sequentially checks each of a plurality of pixels constituting the image data, which is composed of a plurality of pixels that are two-dimensionally arranged and have defined color information, in a predetermined order, and if color information of a specified color is defined for the confirmed pixel, sets a first setting value that is predetermined according to the specified color for the confirmed pixel, and if color information of the specified color is not defined for the confirmed pixel, and if only the first setting value corresponding to the specified color or no first setting value is set for other pixels around the confirmed pixel, in accordance with other pixels above, below, left, and right of the confirmed pixel, sets a value obtained by adding 1 to a first count number of a first counter as a first setting value for the confirmed pixel, and sets the first count number after the addition as the first count value for the confirmed pixel, and sets the set first setting value as the first identification information for the pixel of the first count value. , if only one first setting value equal to or greater than the initial value of the first count number of the first counter plus 1 is set for other pixels above, below, to the left, and right of the confirmed pixel, the first setting value is set as the first setting value of the confirmed pixel and the current first count value is set for the confirmed pixel; if two or more first setting values equal to or greater than the initial value of the first count number of the first counter plus 1 are set for other pixels above, below, to the left, and right of the confirmed pixel, the minimum of the two or more first setting values is set as the first setting value of the confirmed pixel and the current first count value is set for the confirmed pixel; and the first identification information for the first count values of the confirmed pixel and the other pixels above, below, to the left, and right of the confirmed pixel is changed to the minimum of the first identification information for the confirmed pixel and the other pixels above, below, to the left, and right of the confirmed pixel; and a first replacement processing step for replacing the set first setting value with the first identification information for the set first count value for each of the multiple pixels constituting the image data.

The information processing method disclosed herein makes it possible to easily achieve coloring according to the constituent surfaces.

Below, an embodiment of the information processing method according to the present disclosure will be described with reference to the attached drawings.

Figure 1 is a functional block diagram of an example of an information processing device 10 that executes the information processing method of this embodiment.

The information processing device 10 is a device that makes it easy for a user to specify coloring for each face of an object represented by an image of image data such as CAD data.

A face represents a surface of a component that is made up of multiple surfaces. A component is an object represented by image data to be processed by the information processing device 10. A component is, for example, an exterior part that constitutes a structure such as a vehicle, a part that constitutes the structure, etc., but is not limited to these.

The information processing device 10 includes a processing unit 12, a communication unit 14, a memory unit 16, a display unit 18, and an input unit 20. The processing unit 12, the communication unit 14, the memory unit 16, the display unit 18, and the input unit 20 are communicatively connected via a bus 19 or the like.

The communication unit 14 communicates wirelessly or wired with an information processing device external to the information processing device 10 via a network or the like. The memory unit 16 stores various types of information. The display unit 18 displays various types of information. The display unit 18 is, for example, a display that displays images. The information processing device 10 may further include a speaker that outputs sound. The input unit 20 accepts operation input by a user. The input unit 20 is, for example, a pointing device such as a mouse, a keyboard, etc. The display unit 18 and the input unit 20 may be integrated into one unit to form a touch panel.

The processing unit 12 performs various information processing operations.

Figure 2 is a hardware configuration diagram of an example of the processing unit 12.

The processing unit 12 is a hardware configuration that utilizes a normal computer, with a CPU (Central Processing Unit) 11A, a ROM (Read Only Memory) 11B, a RAM (Random Access Memory) 11C, an I/F 11D, etc., interconnected via a bus 11E.

The CPU 11A is a calculation device that controls the processing unit 12 of this embodiment. The ROM 11B stores programs that realize various processes by the CPU 11A. The RAM 11C stores data necessary for various processes by the CPU 11A. The I/F 11D is an interface for sending and receiving data.

The program for executing information processing executed by the processing unit 12 of this embodiment is provided by being pre-installed in ROM 11B or the like. Note that the program executed by the processing unit 12 of this embodiment may be provided by being recorded on a computer-readable recording medium such as a CD-ROM, flexible disk (FD), CD-R, or DVD (Digital Versatile Disk) in a format that can be installed on the information processing device 10 or in a format that can be executed.

Let's go back to Figure 1 and continue the explanation.

The processing unit 12 includes an image data reading unit 12A, a divided face information generating unit 12B, a specified shape inside/outside information generating unit 12E, and a coloring processing unit 12J. The divided face information generating unit 12B includes a first setting unit 12C and a first replacement processing unit 12D. The specified shape inside/outside information generating unit 12E includes a receiving unit 12F, a second setting unit 12G, a third setting unit 12H, and a second replacement processing unit 12I.

The image data reading unit 12A, the divided face information generating unit 12B, the first setting unit 12C, the first replacement processing unit 12D, the specified shape inside/outside information generating unit 12E, the receiving unit 12F, the second setting unit 12G, the third setting unit 12H, the second replacement processing unit 12I, and the coloring processing unit 12J may be partly or entirely realized by, for example, having a processing device such as a CPU execute a program, i.e., by software. Also, partly or entirely of these units may be partly or entirely realized by hardware such as an IC (Integrated Circuit). Also, partly or entirely of these units may be partly or entirely realized by a combination of software and hardware. Also, at least one of these units may be configured to be mounted on an external information processing device communicatively connected to the information processing device 10 via a network or the like.

The image data reading unit 12A reads the image data to be processed. First, the image data reading unit 12A acquires the image data to be processed. For example, the image data reading unit 12A acquires the image data to be processed from an external information processing device via the storage unit 16 or the communication unit 14.

Figure 3 is a schematic diagram of an example of image data 28 to be processed. For example, image data 28 is CAD data and is represented by a bitmap file or the like. Figure 2 shows, as an example of image data 28, a schematic diagram of data representing an image of a component B, such as an exterior part of a vehicle. Component B is made up of a plurality of faces F. As shown in Figure 3, component B is made up of a plurality of faces F, and the plurality of faces F are made up of a plurality of types of shapes and a plurality of types of sizes. In the image data 28, these faces F are separated by frames FR.

The image data reading unit 12A reads the image data 28 using an application such as VBA (Visual Basic for Applications) and stores the pixels that make up the image data 28 in the memory unit 16 as image data in which the pixels are arranged two-dimensionally.

Figure 4 is a schematic diagram of an example of image data 30 after being read by the image data reading unit 12A.

The image data 30 is made up of a plurality of pixels P that are two-dimensionally arranged and have color information defined. In detail, the image data 30 is configured by two-dimensionally arranging a plurality of pixels P along each of the x-axis direction and the y-axis direction in a two-dimensional plane consisting of the x-axis direction and the y-axis direction perpendicular to the x-axis direction. Therefore, the position coordinates of each pixel P that constitutes the image data 30 are defined by the x-coordinate and the y-coordinate. In addition, for each pixel P, color information of the corresponding pixel that constitutes the image data 28 is defined. The color information is represented, for example, by RGB values. The RGB values are expressed, for example, in 256 gradations for each of the R value, G value, and B value.

The image data reading unit 12A reads and processes the image data 28 on VBA, converting it into image data 30 consisting of a plurality of pixels P arranged two-dimensionally and with defined color information, and stores it in the memory unit 16. The sizes of the image data 30 in the x-axis direction and the y-axis direction match the sizes of the image of the image data 28 in the x-axis direction and the y-axis direction, respectively. For the sake of explanation, in this embodiment, the explanation will be given assuming 10 x 10 image data 28 with 10 pixels in the x-axis direction and 10 pixels in the y-axis direction.

As shown in FIG. 4, the image data 30 is composed of a plurality of pixels P constituting each of a frame region 30A corresponding to each frame FR of the face F of the member B, a face region 30B corresponding to the face F, and a background region 30C which is the background G outside the member B.

Let's go back to Figure 1 and continue the explanation.

The divided face information generating unit 12B generates divided face information for each face F of the member B represented by the image of the image data 30, in which the same first identification information Ch1 is set for the pixels constituting the same face F.

The split face information generating unit 12B includes a first setting unit 12C and a first replacement processing unit 12D.

The first setting unit 12C sequentially checks each of the multiple pixels P that make up the image data 30, which is composed of multiple pixels P that are two-dimensionally arranged and have defined color information, in a predetermined order, and performs the following processing.

Figures 5A to 5G are explanatory diagrams of an example of processing by the first setting unit 12C.

As shown in FIG. 5A, first, the first setting unit 12C prepares two-dimensional array information 32. The first setting unit 12C prepares two-dimensional array information 32 with a size in which the number of pixels in the x-axis direction is the number of pixels in the x-axis direction of the image data 30 + 1, and the number of pixels in the y-axis direction is the number of pixels in the y-axis direction of the image data 30 + 1.

Then, the first setting unit 12C sets a first setting value representing "0" for pixels P that are blank spaces in the image data 30 in the two-dimensional array information 32. The first setting value is a numerical value that the first setting unit 12C sets for each pixel P that constitutes the two-dimensional array information 32.

As shown in FIG. 5B, the first setting unit 12C then checks each of the multiple pixels P constituting the image data 30 in the two-dimensional array information 32 in a predetermined order (see the direction of arrow R). The predetermined order represented by the arrow R indicates that each pixel P is checked in order along the direction of arrow R from pixel P at one end of the x-axis direction to pixel P at the other end, and then the process of moving one pixel P in the y-axis direction and checking each pixel P in order along the direction of arrow R from pixel P at one end of the x-axis direction to pixel P at the other end is repeated.

The first setting unit 12C sequentially checks each of the multiple pixels P that make up the image data 30 in the two-dimensional array information 32 along the direction of the arrow R, and if color information of a specified color is defined for the checked pixel P, sets a first setting value that is predetermined according to the specified color to the checked pixel P.

In detail, the first setting unit 12C judges whether the color information of the pixel P at the confirmed pixel position in the image data 30 is the specified color designated as the frame FR. Specifically, it judges whether the pixel P at the confirmed pixel position is a pixel P that constitutes the frame region 30A in the image data 30. Then, if the color information of the confirmed pixel P is the specified color designated as the frame FR, the first setting unit 12C sets "1" as the first setting value for the pixel P at that pixel position.

The first setting unit 12C also determines whether the color information in the image data 30 of the pixel P at the confirmed pixel position is a specified color designated as background G. Specifically, it determines whether the pixel P at the confirmed pixel position is a pixel P that constitutes the background region 30C in the image data 30. If the color information of the confirmed pixel P is a specified color designated as background G, the first setting unit 12C sets "0" as the first setting value for the pixel P at that pixel position.

Therefore, when color information of a specified color is defined for a pixel P confirmed by the first setting unit 12C, a first setting value that is predetermined according to the specified color is set for the confirmed pixel P, so that, as shown in FIG. 5C, the first setting value "1" is set for the pixel P that constitutes the frame region 30A in the two-dimensional array information 32, and the first setting value "0" is set for the pixel P that constitutes the background region 30C.

When the color information of the specified color is not defined for the confirmed pixel P in the two-dimensional array information 32, the first setting unit 12C performs the following processing according to the other pixels P surrounding the confirmed pixel P with the following priority:

First, the first setting unit 12C determines, for a confirmed pixel P for which color information of a specified color is not specified, whether or not only a first setting value corresponding to the specified color is set for other pixels P above, below, to the left, and to the right of the confirmed pixel P, or whether no first setting value is set at all.

In detail, for a confirmed pixel P for which color information of a specified color is not specified, the first setting unit 12C determines whether only the first setting value "1" corresponding to the specified color is set for other pixels P above, below, to the left, and to the right of the confirmed pixel P, or whether no first setting value is set. If this condition is met, the first setting unit 12C adds "1" to the first count number of the first counter and sets the value as the first setting value for the confirmed pixel P.

Up and down refers to the direction along the y-axis direction in the two-dimensional array information 32. Left and right refers to the direction along the x-axis direction in the two-dimensional array information 32. Other pixels P above, below, to the left and right refer to other pixels P adjacent to the confirmed pixel P in the x-axis direction and the y-axis direction, respectively.

The first counter is a counter for counting the first count number, which is a variable for managing allocation numbers, and the initial value of the first count number of the first counter is "1".

Specifically, as shown in FIG. 5D, a scene is assumed in which pixel P35, which is a pixel P at pixel position (x, y) = (3, 5), is the confirmed pixel P. In this case, only "1" or nothing is set as the first setting value for the other pixels P above, below, left and right of the confirmed pixel P35.

In this case, the first setting unit 12C sets the first setting value of the confirmed pixel P35 to "2", which is the value obtained by adding "1" to the initial value "1" of the first counter, which is the current first count number (see FIG. 5D).

The first setting unit 12C also sets the first count number after the addition as the first count value of the confirmed pixel P, and sets the first identification information Ch1 for the pixel P of the first count value to "2", which is the first setting value.

Therefore, the first setting unit 12C sets a first setting value of "2" for pixel P35, and sets a first count value of "2" for pixel P35. The first setting unit 12C also sets "2" as the first identification information Ch1 for the first count value "2", which is the first count number for pixel P35. Therefore, the first identification information Ch1(2)=2 is set. The number in parentheses following the first identification information Ch1 represents the first count value.

Next, the first setting unit 12C determines whether, for a confirmed pixel P for which color information of a specified color is not specified, only one first setting value is set for other pixels P above, below, to the left, and to the right of the confirmed pixel P, the first setting value being equal to or greater than the initial value of the first count number of the first counter plus 1.

In detail, for a confirmed pixel P for which color information of a specified color is not specified, the first setting unit 12C judges whether or not only one first setting value is set for other pixels P above, below, to the left, and to the right of the confirmed pixel P, the sum of the initial value "1" of the first count number of the first counter and "1" being equal to or greater than "2". If this condition is met, the first setting unit 12C sets the set first setting value as the first setting value for the confirmed pixel P.

Specifically, as shown in FIG. 5E, a case is assumed in which pixel P36, which is a pixel P at pixel position (x, y) = (3, 6), is the confirmed pixel P. In this case, the other pixels P above, below, left and right of the confirmed pixel P36 have only one first setting value "2" set, which is equal to or greater than the sum "2" of the initial value "1" of the first count number of the first counter plus "1".

In this case, the first setting unit 12C sets the first setting value "2" as the first setting value of the confirmed pixel P36 (see FIG. 5E).

The first setting unit 12C also sets the current first count value to the confirmed pixel P.

Therefore, the first setting unit 12C sets the first set value "2" for pixel P36 and sets the current first count value "2" as the first count number for pixel P35. Thus, the first set value "2" is set for pixel P36, and the first identification information Ch1 for the first count value "2" is set as first identification information Ch1(2)=2.

As shown in FIG. 5F, similar processing is performed on pixels P38, P39, and P44 at pixel positions (x, y) = (3, 8), (3, 9), and (4, 4), respectively, so that the first set value "3" is set for pixels P38 and P39, and the first set value "4" is set for pixel P44. Furthermore, pixels P38 and P39 are set to the first identification information Ch1(3) = 3, which is the first identification information Ch1 for the first count value "3". Furthermore, pixel P44 is set to the first identification information Ch1(4) = 4, which is the first identification information Ch1 for the first count value "4".

Next, the first setting unit 12C determines whether, for a confirmed pixel P for which color information of a specified color is not specified, other pixels P above, below, to the left, and to the right of the confirmed pixel P have a first setting value of 2 or more set, which is equal to or greater than the initial value of the first count number of the first counter plus 1.

In detail, for a confirmed pixel P for which color information of a specified color is not specified, the first setting unit 12C judges whether or not two or more first setting values, which are equal to or greater than the sum "2" obtained by adding "1" to the initial value "1" of the first count number of the first counter, are set for other pixels P above, below, to the left and right of the confirmed pixel P. If this condition is met, the first setting unit 12C sets the minimum value of the two or more first setting values as the first setting value for the confirmed pixel P.

Specifically, as shown in FIG. 5F, a scene is assumed in which pixel P45, which is a pixel P at pixel position (x, y) = (4, 5), is the confirmed pixel P. In this case, the other pixels P above, below, left and right of the confirmed pixel P45 have a first setting value of 2 or more set, which is equal to or greater than the sum "2" obtained by adding "1" to the initial value "1" of the first count number of the first counter.

In this case, the first setting unit 12C sets the first setting value of the confirmed pixel P36 to "2", which is the minimum of the first setting values "2" and "4" that are equal to or greater than the sum "2" of the above-mentioned values on the top, bottom, left and right, as the first setting value of the confirmed pixel P45 (see FIG. 5F).

The first setting unit 12C also sets the current first count value to the confirmed pixel 45.

Therefore, the first setting unit 12C sets the first setting value "2" for pixel P45 and sets the first count number for pixel P45 to the current first count value of "4". Thus, the first setting value "2" is set for pixel P45, and the first identification information Ch1 for the first count value "4", that is, first identification information Ch1(4)=4, is set.

Then, the first setting unit 12C further changes the first identification information Ch1 for the first count value of the confirmed pixel 45 and the other pixels P above, below, left, and right of the confirmed pixel 45 to the minimum value among the first identification information Ch1 of the confirmed pixel 45 and the other pixels P above, below, left, and right of the confirmed pixel 45.

In detail, the first identification information Ch1 for the confirmed pixel 45's first count value "4" is Ch1(4) = 2. Also, the first identification information Ch1 for the first count value "2" for pixel P35 adjacent to the upper side of the confirmed pixel 45 is Ch1(2) = 2. Also, the first identification information Ch1(4) for the first count value "4" for pixel P44 adjacent to the left side of the confirmed pixel 45 is Ch1(4) = 4.

Therefore, in this case, the first setting unit 12C changes the first identification information Ch1(4)=4 for the first count value "4" of pixel P44 to the first identification information Ch1(4)=2 so that the value of the first identification information Ch1 for these pixels P becomes the smallest value, "2."

The first setting unit 12C sequentially checks each of the multiple pixels P constituting the image data 30 in the two-dimensional array information 32 along the direction of the arrow R, and if the color information of the specified color is not defined for the confirmed pixel P in the two-dimensional array information 32, the above process is performed according to the above priority depending on the other pixels P surrounding the confirmed pixel P, so that a first setting value is set for each pixel P constituting the two-dimensional array information 32, as shown in FIG. 5G. In addition, first identification information Ch1 according to the first count value of each pixel P is set for each pixel constituting the two-dimensional array information 32. In the state shown in FIG. 5G, one of the first count values "2" to "8" is set for each confirmed pixel P for which color information of the specified color is not defined. In addition, the first identification information Ch1 for each of the first count values "2" to "8" of each pixel P is set to any one of the following: first identification information Ch1(2) = 2, first identification information Ch1(3) = 3, first identification information Ch1(4) = 2, first identification information Ch1(5) = 2, first identification information Ch1(6) = 6, first identification information Ch1(7) = 3, first identification information Ch1(8) = 3.

Let's go back to Figure 1 and continue the explanation.

The first replacement processing unit 12D replaces the first set value set for each of the multiple pixels P constituting the image data 30 represented by the two-dimensional array information 32 with the first identification information Ch1 for the set first count value.

Figure 5H is a schematic diagram showing a state in which the first setting value set for each pixel P has been replaced with the first identification information Ch for the first count value set for each pixel P. Through the replacement process by the first replacement processing unit 12D, the first setting value set for each pixel P in the two-dimensional array information 32 shown in Figure 5G, in which color information for the designated color representing the frame FR or background G is not specified, is replaced with the value of the first identification information Ch1 for the first count value set for each pixel P (see replaced pixel area S1 in Figure 5H).

By this replacement process, as shown in FIG. 5I, for each face F of member B represented by the image of image data 30, divided face information 34 is generated in which the same first identification information Ch1 is set for pixels P constituting the same face F.

In detail, as shown in FIG. 5H, pixels P in the divided face information 34 to which a first setting value other than "1" representing the frame FR or "0" representing the background G or margin is set become face area 30B constituting face F (see FIG. 5I). Furthermore, pixels P constituting face area 30B are set to a first setting value of "2" or greater (see FIG. 5H and FIG. 5I). Furthermore, pixels P constituting the same face F are set to the same first setting value (see FIG. 5H and FIG. 5I).

Let's go back to Figure 1 and continue the explanation.

The specified shape inside/outside information generating unit 12E generates specified shape inside/outside information in which the same second identification information is set for pixels P that constitute a specified coloring range in the image of the image data 30.

The specified shape inside/outside information generating unit 12E includes a receiving unit 12F, a second setting unit 12G, a third setting unit 12H, and a second replacement processing unit 12I.

The reception unit 12F receives the specification of the range to be colored in the image of the image data 30.

Figures 6A to 6D are diagrams illustrating an example of specifying the coloring range.

For example, the reception unit 12F displays an image of the image data 30 on the display unit 18. The user operates the input unit 20 while visually checking the displayed image of the image data 30, thereby specifying the coloring target range, which is the area in the image that the user wants to color.

Specifically, for example, the reception unit 12F displays an image of the image data 30 shown in FIG. 6A on the display unit 18. The user draws an outline frame 40 of the range to be colored by operating the input unit 20 while viewing the image. Note that the shape and range of the outline frame 40 of the range to be colored may be any shape and range desired by the user, and is not limited to the form shown in FIG. 6A. For example, consider a scene in which the outline frame 40 of the range to be colored shown in FIG. 6A is drawn by the user operating the input unit 20.

In this case, the reception unit 12F stores the information on the vertex coordinates of the outline frame 40 of the range to be colored in the two-dimensional array information 42.

6B, the reception unit 12F acquires the position coordinates of each vertex of the outline frame 40 of the range to be colored in the image data 30, and stores in the two-dimensional array information 42 for each vertex a percentage position indicating which relative position in the entire image of the image data 30 the position coordinates of each vertex correspond to. For example, assume that the position of a certain vertex in the outline frame 40 of the range to be colored in the x-axis direction is a position corresponding to the center of the entire image of the image data 30 in the x-axis direction. In this case, the reception unit 12F stores 0.5 as the percentage position of the vertex in the x-axis direction. Also assume that the position of a certain vertex in the outline frame 40 of the range to be colored in the y-axis direction is a position corresponding to 20% from the origin in the entire image of the image data 30 in the y-axis direction. In this case, the reception unit 12F stores 0.2 as the percentage position of the vertex in the y-axis direction in the two-dimensional array information 42.

As shown in FIG. 6C, a part of the outline frame 40' of the range to be colored specified by the user may be positioned so as to extend beyond the image size of the image data 30. In this case, the reception unit 12F adjusts the outline frame 40 so that the part of the outline frame 40' of the specified range to be colored that extends beyond the image size of the image data 30 conforms to the outline of the image size.

Then, as shown in Fig. 6D, the first setting unit 12C may store the relative position of the position coordinates of each vertex of the outline frame 40 of the coloring range after trimming in the two-dimensional array information 42. Specifically, the first setting unit 12C may determine the relative position of vertex "3'" of the outline frame 40 of the coloring range after trimming from the ratio of the distance L1 between vertex "3" of the outline frame 40' of the coloring range before trimming and vertex "2" in the image, and the distance L2 between vertex "3'" of the outline frame 40 of the coloring range after trimming and vertex "2" in the image, in Fig. 6D, and store this in the two-dimensional array information 42.

Let's go back to Figure 1 and continue the explanation.

The second setting unit 12G sets an outer frame value representing the outer frame 40 to pixels P that overlap the outer frame 40 of the range to be colored in the two-dimensional array information 42 consisting of a plurality of pixels P, and sets an outer frame value to pixels outside the frame of the image.

Figures 7A and 7B are explanatory diagrams of an example of processing by the second setting unit 12G.

As shown in FIG. 7A, the second setting unit 12G prepares two-dimensional array information 42. The two-dimensional array information 42 is similar to the two-dimensional array information 32. That is, the second setting unit 12G prepares two-dimensional array information 42 with a size in which the number of pixels in the x-axis direction is the number of pixels in the x-axis direction of the image data 30 + 1, and the number of pixels in the y-axis direction is the number of pixels in the y-axis direction of the image data 30 + 1.

Then, the second setting unit 12G uses the relative positions of each vertex of the outline frame 40 stored in the two-dimensional array information 42 by the reception unit 12F to set "1" as the outline value representing the outline frame 40 for the pixels P through which the outline frame 40 of the range to be colored passes.

Furthermore, the second setting unit 12G sets the outside frame value to "0" for pixels P outside the frame of the image of the image data 30 in the two-dimensional array information 42 (see Figure 7B).

Let's go back to Figure 1 and continue the explanation.

The third setting unit 12H sequentially checks, in a predetermined order, each of the pixels P that constitute the two-dimensional array information 42 and that do not have the outer frame value "1" or the outer frame value "0" set, and performs the following processing.

Figures 7C to 7I are explanatory diagrams of an example of information processing by the third setting unit 12H.

As shown in FIG. 7C, the third setting unit 12H sequentially checks, in a predetermined order, each of the pixels P that constitute the two-dimensional array information 42 and that do not have the outer frame value "1" or the outer frame value "0" set thereto. The predetermined order is the direction along the arrow R, and is the same as described above.

The third setting unit 12H performs the following processing for a confirmed pixel P in the two-dimensional array information 42 for which the outer frame value or the outer frame value is not set, according to the other pixels P surrounding the confirmed pixel P, with the following priority:

First, for a confirmed pixel P for which the outer frame value or the outer frame value has not been set, if the outer frame value "0" is set for the other confirmed pixels above, below, to the left, and to the right, or no second setting value is set, the third setting unit 12H sets the outer frame value "0" as the second setting value for the confirmed pixel P, and does not set the second identification information Ch2.

Up and down refers to the direction along the y-axis direction in the two-dimensional array information 42. Left and right refers to the direction along the x-axis direction in the two-dimensional array information 42. Other pixels P above, below, to the left and right refer to other pixels P adjacent to the confirmed pixel P in the x-axis direction and the y-axis direction, respectively.

Specifically, as shown in FIG. 7D, assume that the confirmed pixel P is pixel P11, which is the pixel P at pixel position (x, y) = (1, 1). In this case, the other pixels P above, below, left and right of the confirmed pixel P11 are set to the outer frame value of "0" or are not set to anything.

In this case, the third setting unit 12H sets the outer frame value "0" as the second setting value for the confirmed pixel P11 and does not set the second identification information Ch2.

Next, the third setting unit 12H determines whether or not the border value or the outer border value is not set for the confirmed pixel P, and whether or not the border value "1" is set for the other pixels P above, below, to the left, and to the right of the confirmed pixel P, or whether or not any second setting value is set. If this condition is met, the third setting unit 12H adds "1" to the second count number of the second counter and sets the value as the second setting value for the confirmed pixel P.

The second counter is a counter for counting the second count number, which is a variable for managing allocation numbers, and the initial value of the second count number of the second counter is "1".

Specifically, as shown in FIG. 7E, assume that the confirmed pixel P is pixel P73, which is the pixel P at pixel position (x, y) = (7, 3). In this case, the other pixels P above, below, to the left and right of the confirmed pixel P73 are set to the outer frame value of "1" or are not set to anything.

In this case, the third setting unit 12H sets the second setting value of the confirmed pixel P73 to "2", which is the value obtained by adding "1" to the initial value "1" of the second counter, which is the current second count number (see FIG. 7E).

The third setting unit 12H sets the second count number after the addition as the second count value of the confirmed pixel P, and sets the second set value "2" as the second identification information Ch2 for the pixel P of the second count value.

Therefore, the third setting unit 12H sets the second set value "2" for pixel P73 and sets the second count value "2" for pixel P73. The third setting unit 12H also sets "2" as the second identification information Ch2 for the second count value "2", which is the second count number of pixel P73. Therefore, the second identification information Ch2(2)=2 is set. The number in parentheses following the second identification information Ch2 represents the second count value.

Next, for a confirmed pixel P for which the outer frame value or the outer frame value is not set, if a second setting value equal to or greater than the sum "2" obtained by adding 1 to the initial value of the second count number is set for other pixels P above, below, to the left, and right of the confirmed pixel P, and if the outer frame value "0" is not set for other pixels P above, below, to the left, and right of the confirmed pixel P, the third setting unit 12H sets the minimum value of the second setting values equal to or greater than the sum "2" as the second setting value for the confirmed pixel P.

Specifically, as shown in FIG. 7F, a scene is assumed in which pixel P83, which is a pixel P at pixel position (x, y) = (8, 3), is the confirmed pixel P. In this case, a second setting value of 1 or more is set to the other pixels P above, below, to the left, and to the right of the confirmed pixel P83, which is equal to or greater than the sum "2" obtained by adding "1" to the initial value "1" of the second count number of the second counter, and the outer frame value "0" is not set to the other pixels P above, below, to the left, and to the right.

In this case, the third setting unit 12H sets the second setting value of the confirmed pixel P83 to "2", which is the minimum value of the second setting values "2" that are equal to or greater than the sum "2" of the above-mentioned values above, below, left and right (see FIG. 7F).

The third setting unit 12H also sets the current second count value to the confirmed pixel 83.

Therefore, the third setting unit 12H sets the second set value "2" for pixel P83 and sets the second count number of pixel P83 to the current second count value "2". Thus, the second set value "2" is set for pixel P83, and the second identification information Ch2(2)=2, which is the second identification information Ch2 for the second count value "2", is set.

Then, the third setting unit 12H further changes the second identification information Ch2 for the second count value of the confirmed pixel 83 and the other pixels P above, below, left, and right of the confirmed pixel 83 to the minimum value of the second identification information Ch2 of the confirmed pixel 83 and the other pixels P above, below, left, and right of the confirmed pixel 83. In the pixel 83 in the state shown in FIG. 7F, the only pixel P to which the second identification information Ch2 is set among the pixels P above, below, left, and right of the pixel 83 is pixel 73, and second identification information Ch2(2)=2 is set for pixel 73. Therefore, in this case, the second identification information Ch2 is not changed.

The third setting unit 12H sequentially checks each of the pixels P constituting the image data 30 in the two-dimensional array information 42 along the direction of the arrow R, and performs the above process on the confirmed pixels P to which the outer frame value "1" or the outer frame value "0" is not set, so that the outer frame value "1", the outer frame value "0", or the second setting value is set for each pixel P constituting the two-dimensional array information 42, as shown in FIG. 7G. In addition, the second identification information Ch2 corresponding to the second count value of each pixel P is set for the pixels P constituting the two-dimensional array information 42 to which the second setting value is set. In the state shown in FIG. 7H, the second count value "2" to "4" is set for each pixel P to which the second setting value is set (the pixels P to which the second setting value is set in FIG. 7G) In addition, the second identification information Ch2 for each of the second count values "2" to "4" of each pixel P is set to either second identification information Ch2(2)=2, second identification information Ch2(3)=2, or second identification information Ch2(4)=2.

Let's go back to Figure 1 and continue the explanation.

The second replacement processing unit 12I replaces the set second setting value with the second identification information Ch2 for the set second count value for each of the multiple pixels P that constitute the image data 30 represented by the two-dimensional array information 42.

Figure 7H is a schematic diagram showing a state in which the second setting value set for each pixel P has been replaced with the second identification information Ch2 for the second count value set for each pixel P. Through the replacement process by the second replacement processing unit 12I, the second setting value set for each of the pixels P constituting the outer frame 40 of the range to be colored in the two-dimensional array information 42 shown in Figure 7G has been replaced with the value of the second identification information Ch2 for the second count value set for each of the pixels P (see replaced pixel area S2 in Figure 7H).

As a result of this replacement process, as shown in FIG. 7H, the same second identification information Ch2 is set within the outline frame 40 of the range to be colored specified by the user in the image of the image data 30, an outline value of "1" is set for pixels P that overlap the outline frame 40, and an outline value of "0" is set for pixels P that form the outside of the outline frame 40, generating specified shape inside/outside information 44.

Note that, although not present in the examples shown in Figures 7D to 7G, the third setting unit 12H may set a second setting value of 1 or more to other pixels above, below, to the left and right of a confirmed pixel P to which the outer frame value "1" or the outer frame value "0" has not been set, the second setting value being equal to or greater than the sum "2" obtained by adding 1 to the initial value of the second count number, and the outer frame value "0" may be set to other pixels above, below, to the left and right of the confirmed pixel.

Specifically, as shown in FIG. 7I, a scene is assumed in which pixel P45, which is pixel P at pixel position (x, y) = (4, 5), is the confirmed pixel P. In this case, the third setting unit 12H sets the outer frame value "0" as the second setting value for the confirmed pixel P45.

Let's go back to Figure 1 and continue the explanation.

The coloring processing unit 12J performs coloring processing according to the face F of the member B represented by the image represented by the image data 30, using the image data 30 read by the image data reading unit 12A, the divided face information 34 generated by the divided face information generating unit 12B, and the specified shape inside/outside information 44 generated by the specified shape inside/outside information generating unit 12E.

Figure 8A is a schematic diagram of an example of image data 30 read by the image data reading unit 12A. Figure 8B is a schematic diagram of an example of divided face information 34 generated by the divided face information generating unit 12B. Figure 8C is a schematic diagram of an example of specified shape inside/outside information 44 generated by the specified shape inside/outside information generating unit 12E.

The coloring processing unit 12J performs one of the following coloring processes, for example: coloring online only, coloring within the specified shape frame, coloring faces F that contact the specified shape frame, or coloring faces F that are completely contained within the specified shape frame.

For example, the coloring processing unit 12J receives an instruction to execute any of the coloring processes by a user operating the input unit 20. The coloring processing unit 12J executes the coloring process represented by the execution instruction.

Online-only coloring is a coloring process that colors the area of face F of component B represented by an image that overlaps with the outline frame 40 of the area to be colored.

Figures 9A to 9C are explanatory diagrams of an example of performing coloring processing with online coloring only.

The coloring processing unit 12J performs coloring on pixels P at pixel positions where an outer frame value of "1" is set (see FIG. 9A) in the specified shape inside/outside information 44 and a first setting value of "2" or more is set in the divided face information 34, among the multiple pixels P that make up the image data 30 (see FIG. 8A). Through this coloring process, the coloring processing unit 12J generates colored image data 36A shown in FIG. 9C. The colored image data 36A is an example of colored image data 36. The colored image data 36A is image data in which a colored pixel area 50, which is an area in the image data 30 that overlaps with the outer frame 40 of the area to be colored, is colored on the face F of the member B represented by the image of the image data 30.

Therefore, when a user instructs the coloring processing unit 12J to execute a coloring process that represents coloring only online by operating the input unit 20, the coloring processing unit 12J can easily create colored image data 36A that selectively colors the areas that overlap with the outline frame 40 of the area to be colored on the face F of the component B represented by the image.

Coloring within a specified shape frame is a coloring process that colors the area inside the outline frame 40 of the area to be colored on the face F of the component B represented by the image.

Figures 10A to 10C are explanatory diagrams of an example of performing coloring processing within a specified shape frame.

The coloring processing unit 12J performs coloring on pixels P at pixel positions where a second setting value of "1" or more is set in the specified shape inside/outside information 44 (see FIG. 10A) and a first setting value of "2" or more is set in the divided face information 34, among the multiple pixels P that make up the image data 30 (see FIG. 8A). Through this coloring process, the coloring processing unit 12J generates colored image data 36B shown in FIG. 10C. The colored image data 36B is an example of colored image data 36. The colored image data 36B is image data in which a colored pixel area 50, which is an area inside the outline frame 40 of the area to be colored, in the face F of the member B represented by the image of the image data 30 is colored in the image data 30.

Therefore, when a user operates the input unit 20 to instruct the coloring processing unit 12J to execute a coloring process that represents coloring within a specified shape frame, the coloring processing unit 12J can easily create colored image data 36B that selectively colors the area inside the outline frame 40 of the area to be colored on the face F of the component B represented by the image.

Coloring the face F that contacts the specified shape frame is a coloring process that colors the area of the face F of the part B represented by the image that contacts the outer frame 40 of the area to be colored.

Figures 11A to 11C are explanatory diagrams of an example of performing coloring processing on a face F that contacts a specified shape frame.

The coloring processing unit 12J identifies pixels P at pixel positions where a second setting value of "1" or more is set in the specified shape inside/outside information 44 (see FIG. 11A) and a first setting value of "2" or more is set in the divided face information 34, among the multiple pixels P that make up the image data 30 (see FIG. 8A). The coloring processing unit 12J also identifies other pixels P in the divided face information 34 that have the same first setting value set as the identified pixel P. Then, the coloring processing unit 12J colors these identified pixels P. Through this coloring process, the coloring processing unit 12J generates colored image data 36C shown in FIG. 11C. The colored image data 36C is an example of colored image data 36. The colored image data 36C is image data in which a colored pixel area 50, which is an area of the face F that contacts the outline frame 40 of the coloring target range in the face F of the member B represented by the image of the image data 30, is colored.

Therefore, when a user operates the input unit 20 to instruct the coloring processing unit 12J to execute a coloring process representing the coloring of the face F that contacts the specified shape frame, the coloring processing unit 12J can easily create colored image data 36C that selectively colors the area of the face F of the member B represented by the image that contacts the outline frame 40 of the area to be colored.

Coloring faces F that are completely contained within a specified shape frame is a coloring process that colors the faces F of a component B represented by an image that are completely contained within the outer frame 40 of the range to be colored.

Figures 12A to 12C are explanatory diagrams of an example of performing coloring processing on a face F that is completely contained within a specified shape frame.

The coloring processor 12J counts the number of pixels P for each first setting value set in the division face information 34 of the multiple pixels P that make up the image data 30 (see FIG. 8A) that have a first setting value of "2" or more set in the division face information 34 as the total number (see FIG. 12B). The coloring processor 12J also calculates the number of pixels P for each first setting value at pixel positions where a second setting value of an outer frame value of "1" or more is set in the specified shape inside/outside information 44 (see FIG. 12A) and a first setting value of "2" or more is set in the division face information 34 as the condition hit number.

Then, the coloring processing unit 12J calculates the difference by subtracting the number of condition hits from the total number for each first setting value equal to or greater than "2" in the divided face information 34.

For the specified shape inside/outside information 44 and divided face information 34 shown in Figures 12A and 12B, the coloring processing unit 12J calculates the following differences.

Regarding the first setting value "2": count "14" - condition hit count "6" = difference 8
Regarding the first setting value "6": count "1" - condition hit count "1" = difference 0
Regarding the first setting value "3": count "14" - condition hit count "14" = difference 0

Then, the coloring processing unit 12J performs coloring on the pixel P in the image data 30 for which the first set value is set, where the difference is zero. Through this coloring process, the coloring processing unit 12J generates the colored image data 36D shown in FIG. 12C. The colored image data 36D is image data in which a colored pixel area 50, which is the face F of the member B represented by the image of the image data 30 and which is completely contained within the outline frame 40 of the area to be colored, is colored.

Therefore, when a user instructs the coloring processing unit 12J to perform coloring processing of a face F that is completely contained within a specified shape frame by operating the input unit 20, the coloring processing unit 12J can easily create colored image data 36D that selectively colors the face F of the member B represented by the image.

The coloring processing unit 12J outputs the generated colored image data 36 to the display unit 18. Therefore, by visually checking the colored image data 36 displayed on the display unit 18, the user can easily confirm the colored image data 36 that has been colored in accordance with the execution instructions representing coloring only online, coloring within the specified shape frame, coloring faces F that contact the specified shape frame, or coloring faces F that are completely contained within the specified shape frame.

The coloring processing unit 12J may also display the generated colored image data 36 on a display screen provided by spreadsheet software that can output or set information about pixels for each cell.

The coloring processing unit 12J may also store the generated colored image data 36 in the storage unit 16. The coloring processing unit 12J may also transmit the generated colored image data 36 to an external information processing device via the communication unit 14.

Figure 13 is a flowchart showing an example of the flow of information processing executed by the information processing device 10 of this embodiment.

The image data reading unit 12A reads the image data 28 to be processed and stores it as image data 30 consisting of a plurality of pixels P arranged two-dimensionally and with defined color information (step S100).

The divided face information generating unit 12B generates divided face information 34 for each face F of the member B represented by the image of the image data 30 stored in step S100, in which the same first identification information Ch1 is set for the pixels P constituting the same face F (step S102).

The specified shape inside/outside information generating unit 12E generates specified shape inside/outside information 44 in which the same second identification information Ch2 is set for pixels P that constitute the specified coloring range in the image of the image data 30 stored in step S100 (step S104).

The coloring processing unit 12J uses the image data 30 stored in step S100, the divided face information 34 generated in step S102, and the specified shape inside/outside information 44 generated in step S104 to perform coloring processing according to the face F of the member B represented by the image represented by the image data 30, and generates colored image data 36 (step S106).

Then, the coloring processing unit 12J outputs the colored image data 36 generated in step S106 to the display unit 18 (step S108). Then, this routine ends.

As described above, the information processing device 10 of this embodiment includes a divided face information generating unit 12B. The divided face information generating unit 12B generates divided face information 34 for each constituent surface (face F) of a member B represented by an image of image data 30, in which the same first identification information Ch1 is set for pixels P that constitute the same face F. The divided face information generating unit 12B includes a first setting unit 12C and a first replacement processing unit 12D.

The first setting unit 12C sequentially checks each of the multiple pixels P that constitute the image data 30, which is composed of multiple pixels P that are two-dimensionally arranged and have specified color information, in a predetermined order. If the confirmed pixel P has specified color information of a specified color, the first setting unit 12C sets a first setting value that is predetermined according to the specified color to the confirmed pixel P. If the confirmed pixel P does not have specified color information, and only the first setting value corresponding to the specified color is set to other pixels P above, below, left, and right of the confirmed pixel P in accordance with other pixels P surrounding the confirmed pixel P, or no first setting value is set, the first setting unit 12C sets a value obtained by adding 1 to the first count number of the first counter as the first setting value of the confirmed pixel P, and sets the first count number after the addition as the first count value of the confirmed pixel P, and sets the set first setting value as the first identification information Ch1 for the pixel P of the first count value. Furthermore, when only one first setting value equal to or greater than the sum obtained by adding 1 to the initial value of the first count number of the first counter is set for other pixels P above, below, to the left, and to the right of the confirmed pixel P, the first setting unit 12C sets the first setting value as the first setting value of the confirmed pixel P and sets the current first count value for the confirmed pixel P. Furthermore, when two or more first setting values equal to or greater than the sum obtained by adding 1 to the initial value of the first count number of the first counter are set for other pixels above, below, to the left, and to the right of the confirmed pixel P, the first setting unit 12C sets the minimum value of the two or more first setting values as the first setting value of the confirmed pixel P and sets the current first count value for the confirmed pixel P. The first setting unit 12C further changes the first identification information Ch1 for the first count value of the confirmed pixel P and each of the other pixels P above, below, left, and right of the confirmed pixel P to the minimum value of the first identification information Ch1 for the confirmed pixel P and each of the other pixels P above, below, left, and right of the confirmed pixel P. The first replacement processing unit 12D replaces the set first setting value with the first identification information Ch1 for the set first count value for each of the multiple pixels P that make up the image data 30.

In this way, by performing the above processing, the divided face information generating unit 12B of the information processing device 10 of this embodiment generates divided face information 34 for each constituent surface (face F) of the member B represented by the image of the image data 30, in which the same first identification information Ch1 is set for the pixels P constituting the same face F.

Therefore, the information processing method executed by the information processing device 10 of this embodiment can easily perform coloring processing according to the face F by using the divided face information 34 in which the same first identification information Ch1 is set for the pixels P that constitute the same face F.

Therefore, the information processing method of this embodiment can easily achieve coloring according to the face F (constituent surface).

In addition, according to the information processing method of this embodiment, image data 28 can be processed without using special image editing software, and coloring according to face F can be easily achieved, making it possible to realize versatile coloring processing.

In addition, according to the information processing method of this embodiment, the user can check the colored image data 36 that has been subjected to coloring processing according to the execution instruction by simply issuing an execution instruction indicating coloring only online, coloring within the specified shape frame, coloring faces F that contact the specified shape frame, or coloring faces F that are completely contained within the specified shape frame.

Therefore, in addition to the above-mentioned effects, the information processing method of this embodiment can reduce the amount of work required to create coloring instructions for each face F and colored image data 36 in which coloring has been applied to a specified range.

The programs for executing the above processes executed by the information processing device 10 of the above embodiment may be stored in the HDD. Also, the programs for executing the above processes executed by the information processing device 10 of the above embodiment may be provided in advance in the ROM 11B.

The program for executing the above-mentioned processes executed by the information processing device 10 of the above-mentioned embodiment may be stored in an installable or executable file format on a computer-readable storage medium such as a CD-ROM, CD-R, memory card, DVD (Digital Versatile Disk), or flexible disk (FD) and provided as a computer program product.
