Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.
Hereinafter, a combination of colors or a combined color is referred to as a color scheme. Adding a plurality of colors is also called a color scheme.
Note that the color described below may include an achromatic color.

The color arrangement information referred to below is information indicating the color arrangement. That is, the color combination indicates the color combination.
Further, the color arrangement sample described below is information including a plurality of pieces of color arrangement information. That is, a plurality of color schemes are shown by the color scheme sample. Hereinafter, a plurality of color schemes indicated by the color scheme sample as information are also referred to as color scheme samples.
Moreover, the color scheme sample group described below is a set of color scheme samples. Both a set of color scheme samples as information and a set of color scheme samples as a plurality of color schemes are referred to as a color scheme sample group. The number of color arrangement samples included in the color arrangement sample group may be one, or two or more.

  FIG. 1 is a schematic block diagram showing a functional configuration of a color arrangement support apparatus according to an embodiment of the present invention. In the figure, the color arrangement support device 100 includes a display unit 110, an operation input unit 120, a template image acquisition unit 130, a storage unit 180, and a control unit 190. The storage unit 180 includes a color arrangement information storage unit 181, a template image storage unit 182, and an adjacent relationship information storage unit 183. The control unit 190 includes an initial candidate image generation unit 191, a similar color scheme acquisition unit 192, and a next generation candidate image generation unit 193.

  The color arrangement support device 100 supports color arrangement on an image. Specifically, the color arrangement support device 100 acquires an image whose area is designated by the user, and presents a candidate image with a color added to each area of the obtained image. The color arrangement support device 100 repeats the presentation of new candidate images until an image that the user likes is obtained. The color arrangement support device 100 is configured using, for example, a computer.

The display unit 110 has a display screen such as a liquid crystal panel, and displays various images. In particular, the display unit 110 displays the candidate image. That is, the display of the candidate image by the color arrangement support device 100 is performed by the display unit 110 displaying the candidate image.
The operation input unit 120 includes operation devices such as a mouse and a keyboard, for example, and receives user operations. In particular, the operation input unit 120 receives a selection operation for a candidate image displayed on the display unit 110 and an operation for instructing display of a new candidate image.

The template image acquisition unit 130 acquires a template image. The template image here is an image whose area is designated by the user, and includes a plurality of areas. Further, the candidate images referred to here are images that are colored for each area of the template image.
The template image is used as an original image of candidate images that the color arrangement support apparatus 100 presents to the user. Specifically, the color arrangement support device 100 presents an image with a color for each region of the template image as a candidate image.

  FIG. 2 is an explanatory diagram illustrating an example of a template image. In the figure, the difference in color is indicated by the difference in pattern. The user designates the region of the template image by assigning the same color to the same region, and each of the portions A11, A12, and A13 is one region. On the other hand, the same color is given to the parts A14 and A15, and the color arrangement support apparatus 100 handles the parts A14 and A15 together as one area. Specifically, the color arrangement support apparatus 100 assigns the same color to the portions A14 and A15 when generating candidate images.

In the example of FIG. 2, since the area is designated by color, there may be no area boundary line. The line drawn in the template image is drawn as a line also in the candidate image.
Note that the numbers “0”, “1”, “2”, and “3” attached to each area in FIG. 2 indicate the identification numbers for identifying the areas for explanation in FIG. It is. These identification numbers need not be displayed on the template image.

  Note that the method of specifying the template image area by the user is not limited to the method of adding a color as described above. For example, the user may draw the boundary of the area with a line. In this case, the color arrangement support apparatus 100 handles each part delimited by a line as an area. Further, when it is desired that the separated portions such as the portions A14 and A15 in FIG. 2 be one region, the user should describe information for identifying the region as in the identification number shown in FIG. Also good.

Alternatively, the user may generate a template image by inserting a basic figure such as a circle or a triangle using a drawing tool. In this case, the color arrangement support device 100 treats each inserted basic graphic as a region.
Note that when the user designates an area with a color, as described above, the color arrangement support device 100 may treat a portion with the same color as one area. Alternatively, the color arrangement assisting apparatus 100 may treat the separated parts as different areas even when the same color is given. When an image is complicated and divided into many parts, it is conceivable that the user unintentionally gives the same color to a plurality of parts. In this case, the color arrangement support apparatus 100 can reflect the user's intention more accurately by treating the separated parts as different areas even if the same color is given. It should be noted that the user may be able to set whether the distant portions with the same color are to be one region or different regions.

  Various methods can be used as a method by which the template image acquisition unit 130 acquires a template image. For example, the template image acquisition unit 130 includes a communication circuit, and receives a template image from another device as image data. Alternatively, the template image acquisition unit 130 may be configured to include a connection interface of a storage device such as a USB (Universal Serial Bus) flash memory, and image data of the template image may be read from the connected storage device. Alternatively, the template image acquisition unit 130 may activate a drawing tool and acquire a template image drawn by the user.

The storage unit 180 stores various information. The storage unit 180 may be configured using a storage device built in the color arrangement support apparatus 100, or may be configured using an external storage device.
The color arrangement information storage unit 181 stores in advance a color arrangement sample including a plurality of color arrangement information that is information indicating color arrangement (in other words, the storage unit 180 is color arrangement information that is information indicating color arrangement in the color arrangement information storage unit 181). Singular or multiple color arrangement samples including a plurality of color arrangement samples). Here, it is before the color arrangement support device 100 generates a candidate image. The color arrangement information stored in the color arrangement information storage unit 181 is used by the color arrangement support apparatus 100 to generate a candidate image.

Here, the color arrangement information will be described with reference to FIGS. 3 and 4. First, the color arrangement sample group indicated by the color arrangement information will be described with reference to FIG. 3, and then the data structure of the color arrangement information will be described with reference to FIG.
FIG. 3 is an explanatory diagram illustrating an example of a color sample group. In the figure, the difference in color is indicated by the difference in pattern.

In the example of FIG. 3, the color scheme sample group includes a plurality of color scheme samples, and each of the color scheme samples indicates a plurality of color schemes obtained by combining three colors.
In the example of FIG. 3, themes such as “Pure” and “Vivid” are shown in each of the color arrangement samples. By combining a plurality of color schemes as a color scheme sample, the color schemes are classified by theme.

  FIG. 4 is an explanatory diagram illustrating an example of a data structure in which the storage unit 180 stores a color arrangement sample group. This figure shows an example of the data structure when the storage unit 180 stores the color arrangement sample group shown in FIG. In FIG. 4, the storage unit 180 stores the color arrangement sample group as tabular data, and one row indicates one color arrangement information. The color arrangement information shown in one row includes items of “classification”, “color arrangement number”, and “lightness”, “hue”, and “saturation” for each of colors 1 to 3.

The “classification” item indicates the classification of the color sample swatches such as “pure” and “vivid”. Hereinafter, the classification indicated in the classification item is referred to as a classification of color arrangement information.
The item “color arrangement number” indicates an identification number for identifying a color arrangement. In the example of FIG. 4, a serial number for each classification of color arrangement information is used as the color arrangement number. Therefore, the color arrangement information can be uniquely specified by the combination of the color arrangement information classification and the color arrangement number.
Note that N shown in FIG. 4 is a positive integer indicating the number of color arrangement information classified as pure. It is preferable that N is a relatively large number so that the color arrangement support device 100 can display various candidate images. That is, it is preferable that the color arrangement sample includes a certain number of color arrangements.

“Color 1”, “Color 2”, and “Color 3” respectively correspond to colors included in the color scheme. The combination of “Color 1”, “Color 2”, and “Color 3” corresponds to a combination of three colors in the color scheme.
The color of color 1 is shown by the combination of the lightness, hue, and saturation shown in the items of “lightness”, “hue”, and “saturation” of color 1. Similarly, the color of the color 2 is shown by the combination of the lightness, hue, and saturation shown in the “lightness”, “hue”, and “saturation” items of the color 2. The color of the color 3 is indicated by the combination of the lightness, hue, and saturation shown in the items of “lightness”, “hue”, and “saturation” of the color 3.

The number of colors indicated by one color arrangement information is not limited to three illustrated in FIG. 4 and may be two or more.
In addition, the number of colors indicated by the color scheme information may be the same for all the color scheme information. For example, all color arrangement information may indicate combinations of three colors. Alternatively, there may be color arrangement information with different numbers of colors. For example, color arrangement information indicating a combination of three colors and color arrangement information indicating four colors may be mixed.

Note that the color expression format in the color arrangement information stored in the storage unit 180 is not limited to the display format based on lightness, hue, and saturation exemplified in FIG. For example, the storage unit 180 may store colors using combinations of pixel values of red, green, and blue (R, G, and B).
The number of color arrangement samples included in the color arrangement sample group may be one or more. When only one color arrangement sample is included in the color arrangement sample group, the “classification” item may not be included in the data structure in which the storage unit 180 stores the color arrangement sample group.

The template image storage unit 182 stores the template image acquired by the template image acquisition unit 130.
The adjacency information storage unit 183 stores adjacency information indicating the adjacency of the areas included in the template image.

FIG. 5 is an explanatory diagram illustrating an example of adjacency information. In the same figure, the adjacent relationship of the area | region in the template image of FIG. 2 is shown.
Each row and column in FIG. 5 is associated with the region in FIG. 2 by an identification number, and “1” indicates that the region is adjacent, and “0” indicates that the region is not adjacent. Yes.
For example, in FIG. 2, the area of identification number 0 and the area of identification number 1 are adjacent. Therefore, a value “1” indicating that there is an adjacency is stored in the column C11 where the row with the identification number 0 and the column with the identification number 1 intersect. Similarly, the value “1” is also stored in the column C12 where the row of the identification number 1 and the column of the identification number 0 intersect.
On the other hand, in FIG. 2, the area of identification number 0 and the area of identification number 3 are not adjacent. Therefore, a value “0” indicating no adjacency is stored in the column C21 where the row with the identification number 0 and the column with the identification number 3 intersect. Similarly, the value “0” is also stored in the column C22 where the row with the identification number 3 and the row with the identification number 0 intersect.

  The adjacency information storage unit 183 stores adjacency information in a tabular data structure, for example, as in the example of FIG. Alternatively, the adjacency information storage unit 183 stores, for each combination of two areas, the identification information of the two areas and “1” and “0” indicating the presence / absence of the adjacency in association with each other. The adjacency information may be stored in the data structure.

  The control unit 190 controls each unit of the color arrangement support apparatus 100 to execute various functions. The control unit 190 is realized, for example, when a CPU (Central Processing Unit) included in the color arrangement support device 100 reads out and executes a program from the storage unit 180.

The initial candidate image generation unit 191 generates, for each of a plurality of color arrangement information included in the color arrangement sample, a candidate image in which a template image is colored based on the color arrangement indicated by the color arrangement information.
Specifically, the initial candidate image generation unit 191 selects color arrangement information included in the color arrangement sample selected by the user from among the color arrangement information stored in the color arrangement information storage unit 181 (that is, according to the theme selected by the user). A plurality of (color scheme information) are selected at random. Then, for each selected color arrangement information, the initial candidate image generation unit 191 generates a candidate image by adding a color to the template image based on the color arrangement indicated by the color arrangement information. Details of processing performed by the initial candidate image generation unit 191 will be described later.
Hereinafter, the candidate image generated by the initial candidate image generation unit 191 is referred to as a first generation candidate image.

The similar color arrangement acquisition unit 192 selects color arrangement information indicating a color arrangement similar to the color arrangement of the candidate image selected by the user. Specifically, the similar color scheme acquisition unit 192 selects color scheme information indicating a color scheme that satisfies the similar condition in relation to the color scheme that is the basis of the candidate image selected by the selection operation among the plurality of candidate images. In particular, the similar color arrangement acquisition unit 192 selects the color arrangement information from the color arrangement information included in the color arrangement sample selected by the user. The similarity condition here is a predetermined condition set as a condition where two color schemes are similar.
The color arrangement information selected by the similar color acquisition unit 192 is used for processing to generate a candidate image having a color arrangement similar to the candidate image selected by the user. Hereinafter, the process of generating a candidate image having a color scheme similar to the candidate image selected by the user is referred to as crossover.

The next-generation candidate image generation unit 193 performs crossover based on the candidate image selected by the similar color scheme acquisition unit 192. Specifically, the next generation candidate image generation unit 193 generates a candidate image with a color added to the template image based on the color scheme selected by the similar color scheme acquisition unit 192.
Further, the next generation candidate image generation unit 193 generates a candidate image with a color added to the template image based on the color scheme indicated by the color scheme information selected at random from the color scheme sample selected by the user. Hereinafter, the process of generating a candidate image based on randomly selected color arrangement information is referred to as mutation.
Details of processing performed by the next generation candidate image generation unit 193 will be described later.

Next, an outline of processing performed by the color arrangement support device 100 will be described with reference to FIGS. Note that in FIGS. 6 to 9, different colors are indicated by differences in patterns.
FIG. 6 is an explanatory diagram showing another example of a template image. Also in the template image of FIG. 6, the area is designated by the user as in the case of the template image of FIG. 2. In the template image of FIG. 6, the background is not colored. As a result, the background is also excluded from the region to be colored in the candidate image. That is, the background is not colored even in the candidate image.

FIG. 7 is an explanatory diagram illustrating a display example of a first generation candidate image displayed on the display unit 110. The display screen of the display unit 110 shown in the figure includes an area A21 for displaying candidate images and an area A22 for displaying push buttons for receiving user operations.
Twelve first generation candidate images generated by the initial candidate image generation unit 191 are displayed in the area A21. The initial candidate image generation unit 191 randomly selects 12 pieces of color arrangement information from the color arrangement sample selected by the user, and generates a candidate image by applying the color arrangement indicated by the color arrangement information to the template image for each selected color arrangement information. doing.

In addition, among the 12 candidate images displayed by the display unit 110, three candidate images of images P11, P12, and P13 are selected by the user. The selection of the candidate image is performed, for example, when the operation input unit 120 receives a selection operation of the candidate image by mouse click or touch on the touch panel.
The candidate image selected by the user is used by the next generation candidate image generation unit 193 to generate a candidate image by crossover. Specifically, the similar color arrangement acquisition unit 192 selects color arrangement information indicating a color arrangement similar to the color arrangement of the selected candidate image. Then, the next generation candidate image generation unit 193 generates a candidate image based on the color scheme selected by the similar color scheme acquisition unit 192.

  Note that the number of candidate images displayed on the display unit 110 is not limited to 12 shown in the example of FIG. 7 and may be two or more. However, if the number of candidate images displayed on the display unit 110 is too small, the user's options may be narrowed, and it may take time until an image that the user likes can be obtained. On the other hand, if the number of candidate images displayed on the display unit 110 is too large, the user may not be able to select candidate images, or it may take time for the user to select candidate images. From this point, the number of candidate images displayed by the display unit 110 is considered to be about 12.

In the area A22, four push buttons B11 to B14 are shown. The push button is pressed, for example, when the operation input unit 120 receives an operation on the display area of the push button by a mouse click or a touch on the touch panel, similarly to the selection of the candidate image.
The push button B11 (“enlarge” button) is a push button for enlarging and displaying the candidate image. When the user selects any of the candidate images displayed in the area A21 and presses the push button B11, the display unit 110 displays the selected candidate image in an enlarged manner. Thereby, the user can confirm the candidate image in detail.

  The push button B12 (“clear” button) is a push button for canceling the selection. When the user wants to cancel the selection of the candidate image, the user presses the push button B12. Then, the control unit 190 puts all candidate images displayed on the display unit 110 into a non-selected state. In accordance with this, the display unit 110 cancels the display of selection of candidate images (in the example of FIG. 7, the display that surrounds the candidate images with a square).

  The push button B13 (“next generation” button) is a push button for instructing generation of a new candidate image. When the user wants to obtain a new candidate image, the user selects some of the candidate images displayed on the display unit 110 and presses the push button B13. For example, the user presses the push button B13 while selecting three candidate images as in the example of FIG. Then, the next generation candidate image generation unit 193 performs crossover and mutation to generate a candidate image. Then, as in the example of FIG. 8 to be described later, the display unit 110 sets the selected candidate image, the candidate image generated by crossover, and the candidate image generated by mutation as the next-generation candidate images. indicate.

  Note that the number of candidate images selected when the user wants to obtain a new candidate image may be fixed or variable. For example, the user may always select three candidate images. Alternatively, the user may select a relatively favorite candidate image within a predetermined number of ranges (for example, a range of 1 to 6).

  The push button B14 (“end” button) is a push button for confirming the image. When the user likes any of the candidate images displayed on the display unit 110, the user selects a favorite candidate image and presses the push button B14. Then, the color arrangement support device 100 outputs the selected candidate image as a final image, and ends the process.

  Various methods can be used as a method by which the color arrangement support device 100 outputs an image. For example, the display unit 110 may display an image. Alternatively, a printer may be connected to the color arrangement support apparatus 100, and the color arrangement support apparatus 100 may cause the printer to print an image. Alternatively, the color arrangement support apparatus 100 may transmit image data to another device. Alternatively, a storage device such as a USB flash memory may be connected to the color arrangement support apparatus 100, and the color arrangement support apparatus 100 may write image data in the storage device.

FIG. 8 is an explanatory diagram illustrating a display example of a second generation candidate image displayed on the display unit 110. Here, the candidate image displayed on the display unit 110 next to the first generation candidate image is referred to as a second generation candidate image. Similarly, the candidate image displayed on the display unit 110 next to the Nth (N is a positive integer) generation candidate image is referred to as a (N + 1) th generation candidate image.
FIG. 8 shows a display example of a candidate image when the push button B13 (“next generation” button) is pressed in the example of FIG. In the example of FIG. 8, 12 candidate images are displayed as in the case of FIG. On the other hand, in FIG. 8, the display area of these 12 candidate images is divided into three areas A31, A32, and A33.

In the area A31, candidate images selected by the user in the previous generation are displayed. In the example of FIG. 8, three candidate images of images P11, P12, and P13 selected in FIG. 7 are displayed.
In the area A32, candidate images obtained by crossover based on candidate images selected by the user in the previous generation are displayed. In the example of FIG. 8, the image obtained by crossing based on the image P11, the image obtained by crossing based on the image P12, and the image obtained by crossing based on the image P13 are all. 6 are displayed.
In the area A33, candidate images generated by mutation are displayed. In the example of FIG. 8, three images generated by mutation are displayed.
However, the arrangement of the areas A31, A32, and A33 is not limited to that shown in FIG. Further, the candidate images may be displayed in a mixed manner without being divided for each region.

User operations on the display screen shown in FIG. 8 are the same as those in FIG.
Specifically, when the user selects any of the displayed candidate images and presses the “enlarge” button, the display unit 110 displays the selected candidate image in an enlarged manner.
When the user presses the “Clear” button, the control unit 190 puts all candidate images displayed on the display unit 110 into a non-selected state.
When the user selects several (for example, three) candidate images and presses the “next generation” button, the next-generation candidate image generation unit 193 executes crossover or mutation to generate candidate images, The display unit 110 displays the next generation candidate images.
When the user selects any one of the candidate images and presses an “end” button, the color arrangement support device 100 outputs the selected candidate image as a final image and ends the process.

  As in the case of FIG. 8, the candidate image selected in the previous generation, the candidate image obtained by crossover, and the candidate image obtained by mutation are also displayed on the display screen after the third generation. The In addition, user operations on the third and subsequent generation display screens are the same as those in FIGS.

  FIG. 9 is an explanatory diagram illustrating an example of an image finally selected by the user. As described above, when the user selects one of the candidate images and presses the “end” button, the color arrangement support device 100 outputs the selected candidate image as a final image and ends the processing.

Next, with reference to FIGS. 10 to 12, the process performed by the color arrangement support device 100 will be described in more detail.
FIG. 10 is a flowchart illustrating an example of a processing procedure in which the color arrangement support apparatus 100 performs color arrangement support.
In the process of FIG. 10, the template image acquisition unit 130 acquires a template image (step S101). As described above, various methods can be used as a method by which the template image acquisition unit 130 acquires a template image.

Next, the control unit 190 acquires adjacency information based on the template image obtained in step S101 (step S102). For example, the control unit 190 scans the template image in the vertical direction and the horizontal direction, and generates adjacency information as described with reference to FIG.
Next, the operation input unit 120 accepts a user operation for selecting a color sample (step S103). For example, the display unit 110 displays a color sample theme such as “Pure” or “Vivid”. Here, in addition to or instead of displaying the theme of the color scheme, a sample of the color scheme may be displayed.
Then, the operation input unit 120 receives a user operation for selecting one of the color arrangement samples displayed on the display unit 110.
In this way, the user's preference can be reflected in the candidate image generated by the color arrangement support device 100 by the user selecting the color arrangement sample. The user may be allowed to specify a plurality of color samples. Alternatively, the user may be able to specify the entire color sample group without specifying a specific color sample.

Next, the initial candidate image generation unit 191 generates a first generation candidate image (step S104). Then, as described with reference to FIG. 7, the display unit 110 displays the first generation candidate images (step S105), and the operation input unit 120 receives a candidate image selection operation (step S106).
Then, the control unit 190 determines whether or not a user operation for confirming an image has been performed (step S107). Specifically, the control unit 190 determines whether or not a user operation for pressing the “end” button described above has been performed.

When the control unit 190 determines that the user operation for confirming the image has not been performed (step S107: NO), the next generation candidate image generation unit 193 generates a next generation candidate image in steps S111 to S115. The display unit 110 displays the next generation candidate images.
Specifically, first, as in the example of the region A31 in FIG. 8, the display unit 110 displays the candidate image selected in step S106 (step S111).

Further, the next generation candidate image generation unit 193 generates a candidate image by crossover (step S112), and the display unit 110 displays the candidate image obtained in step S112 as in the example of the region A32 in FIG. (Step S113).
Further, the next generation candidate image generation unit 193 generates a candidate image due to sudden displacement (step S114), and the display unit 110 displays the candidate image obtained in step S114 as in the area A33 of FIG. Step S115).
After step S115, the process proceeds to step S106.

On the other hand, when the control unit 190 determines in step S107 that a user operation to confirm the image has been performed (step S107: YES), the color arrangement support device 100 sets the candidate image selected in step S106 as a final image. Output (step S121).
After step S121, the process of FIG.

FIG. 11 is a flowchart illustrating an example of a processing procedure in which the initial candidate image generation unit 191 generates a first generation candidate image. The initial candidate image generation unit 191 performs the process of FIG. 11 in step S104 of FIG.
In the process of FIG. 11, the initial candidate image generation unit 191 executes a loop L11 that repeats the process of generating one candidate image by the number of candidate images to be generated (step S201).
In the loop L11, the initial candidate image generation unit 191 randomly selects one color arrangement information included in the color arrangement sample selected in step S103 of FIG. 10 from the color arrangement information stored in the color arrangement information storage unit 181. (Step S202).

  Next, the initial candidate image generation unit 191 executes a loop L12 that performs processing for each region included in the template image (step S203). In the loop L12, processing is performed in order from the region with the largest number of neighbors indicated in the neighbor relation information. In the following, a region that is a processing target in the loop L12 is referred to as a target region.

In the loop L12, the initial candidate image generation unit 191 selects a color to be added to the target area from the colors indicated by the color arrangement information selected in Step S202 (Step S204).
In step S204, the initial candidate image generation unit 191 may select colors in a predetermined order, such as selecting colors in order from the front in the color arrangement information. Alternatively, the initial candidate image generation unit 191 may randomly select a color.

When the initial candidate image generation unit 191 selects colors in a predetermined order, the colors may be selected again in a predetermined order after using each color once. Alternatively, after using each color once, the initial candidate image generation unit 191 may randomly select a color.
In addition, the initial candidate image generation unit 191 may use all the colors indicated by the color scheme information selected in step S202 to color the image. Alternatively, the initial candidate image generation unit 191 may be able to attach only a part of the color indicated by the color arrangement information selected in step S202 to the image.

Next, the initial candidate image generation unit 191 determines whether or not the color selected in step S204 is the same as the color assigned to the area adjacent to the target area (step S205).
When it is determined that the color is the same as the color attached to the region adjacent to the target region (step S205: YES), the initial candidate image generation unit 191 changes the lightness of the color attached to the target region, thereby adjacent to the target region. The color is different from that of the area (step S206).

In step S206, the initial candidate image generation unit 191 may change either one or both of hue and saturation in addition to or instead of brightness.
In addition, the initial candidate image generation unit 191 may always change the colors of adjacent areas (that is, areas adjacent to each other). Alternatively, the initial candidate image generation unit 191 may be able to keep the colors of adjacent regions the same.
Note that in step S206, the initial candidate image generation unit 191 replaces or in addition to the color attached to the target region with at least one of the brightness, hue, and saturation of the color attached to the region adjacent to the target region. One of them may be changed.

Next, the initial candidate image generation unit 191 colors the target area (step S207). After step S206 or when it is determined in step S205 that the color is different from the color assigned to the area adjacent to the target area (step S205: NO), the process proceeds to step S207.
After step S207, the initial candidate image generation unit 191 performs a termination process of the loop L12 (step S208). Specifically, the initial candidate image generation unit 191 determines whether or not the process of the loop L12 has been performed on all regions included in the template image. If it is determined that there is an unprocessed area, the process returns to step S203, and the process of loop L12 is subsequently executed for the unprocessed area. On the other hand, when it is determined that the processing of the loop L12 has been performed on all the regions included in the template image, the loop L12 is terminated.

When the loop L12 is finished in step S208, the initial candidate image generation unit 191 performs a termination process of the loop L11 (step S209). Specifically, the initial candidate image generation unit 191 determines whether or not a predetermined number of candidate images have been generated. For example, in the case of the example described with reference to FIGS. 6 to 9, the initial candidate image generation unit 191 determines whether 12 candidate images have been generated as illustrated in FIG. 7.
If it is determined that the planned number of candidate images has not been generated, the process returns to step S201 to continue generating candidate images. On the other hand, when it is determined that the planned number of candidate images has been generated, the loop L11 is terminated.
When the loop L11 is terminated in step S209, the process of FIG. 11 is terminated.

FIG. 12 is a flowchart illustrating an example of a processing procedure in which the control unit 190 executes crossover. The control unit 190 performs the process of FIG. 12 in step S112 of FIG.
In the process of FIG. 12, the next-generation candidate image generation unit 193 executes a loop L21 that repeats the process of generating one candidate image by the number of candidate images to be generated (step S301).

In the loop L21, the similar color arrangement acquisition unit 192 out of the color arrangement information stored in the color arrangement information storage unit 181 and the color arrangement information included in the color arrangement sample selected in step S103 in FIG. 10, step S106 in FIG. 10. The color arrangement information satisfying the similarity condition is selected in relation to the color arrangement information that is the basis of the candidate image selected in (Step S302).
Here, various conditions can be used as the similar condition. For example, the color arrangement information storage unit 181 stores the color arrangement numbers of similar color arrangement information close to each other. Then, in step S302, the similar color arrangement acquisition unit 192 has a color arrangement number within a predetermined number (for example, within plus or minus 2) before and after the color arrangement number of the color arrangement information that is the basis of the candidate image selected in step S106 in FIG. Select the color scheme information. In this case, the similarity condition is that the absolute value of the difference between the color arrangement numbers is not more than a predetermined value.

  In this case, the similar color arrangement acquisition unit 192 may always select color arrangement information different from the color arrangement information that is the basis of the candidate image selected in step S106 of FIG. Alternatively, the similar color arrangement acquisition unit 192 may be able to select the same color arrangement information as the color arrangement information that is the basis of the candidate image selected in step S106 of FIG. Even when the similar color scheme acquisition unit 192 selects the same color scheme information, the next-generation candidate image generation unit 193 changes the order of selecting colors to change the candidate image different from the candidate image selected in step S106 of FIG. Can be generated.

Alternatively, in step S302, the similar color arrangement acquisition unit 192 may select new color arrangement information based on the color value indicated by the color arrangement information. For example, the similar color scheme acquisition unit 192 determines the color scheme information that is the basis of the candidate image selected in step S106 in FIG. 10 and the hue value difference of color 1, the chroma value difference of color 1, and the color 1 Lightness value difference, color 2 hue value difference, color 2 saturation value difference, color 2 lightness value difference, color 3 hue value difference, color 3 saturation value difference For both the value difference and the lightness value difference of the color 3, color arrangement information in which the absolute value of the difference is equal to or less than a predetermined value may be selected. In this case, the similarity condition is that the absolute value of the difference between the color values indicated by the color arrangement information is not more than a predetermined value.
In step S302, the similar color arrangement acquisition unit 192 may be able to select color arrangement information satisfying the similarity condition from color arrangement information not included in the color arrangement sample selected in step S103 in FIG.

The processing in steps S303 to S309 is the same as the processing performed by the initial candidate image generation unit 191 in steps S203 to S209 in FIG.
Specifically, the next generation candidate image generation unit 193 executes a loop L22 that performs processing for each region included in the template image (step S303). In the loop L22, processing is performed in order from the region with the largest number of neighbors indicated in the neighbor relation information. As described above, the next-generation candidate image generation unit 193 adds colors in order from the region having the largest number of adjacent regions among the regions included in the template image. Hereinafter, an area that is a processing target in the loop L22 is referred to as a target area.

In the loop L22, the next generation candidate image generation unit 193 selects a color to be added to the target region from the colors indicated by the color arrangement information selected in Step S302 (Step S304).
In step S304, the next-generation candidate image generation unit 193 may select colors in a predetermined order, such as selecting colors sequentially from the front in the color arrangement information. Or you may make it the next-generation candidate image generation part 193 select a color at random.
Further, the next generation candidate image generation unit 193 may use all the colors indicated by the color arrangement information selected in step S302 to color the image. Alternatively, the next-generation candidate image generation unit 193 may be able to attach only a part of the color indicated by the color arrangement information selected in step S302 to the image.

Next, the next generation candidate image generation unit 193 determines whether or not the color selected in step S304 is the same as the color assigned to the area adjacent to the target area (step S305).
When it is determined that the color is the same as the color attached to the region adjacent to the target region (step S305: YES), the next generation candidate image generation unit 193 changes the lightness of the color attached to the target region, thereby changing the adjacent color. The color is different from that of the region to be processed (step S306). As described above, the next generation candidate image generation unit 193 adds different colors to adjacent areas among the areas included in the template image. In particular, when the next-generation candidate image generation unit 193 determines that the color to be applied to the adjacent regions among the regions included in the template image is the same, the next-generation candidate image generation unit 193 attaches a color with a changed brightness to at least one of the adjacent regions. With a different color.

In step S306, the next-generation candidate image generation unit 193 may change either one or both of hue and saturation in addition to or instead of brightness.
Further, the next-generation candidate image generation unit 193 may always change the colors of adjacent regions. Alternatively, the next generation candidate image generation unit 193 may be able to keep the colors of adjacent regions the same.
In step S306, the next generation candidate image generation unit 193 replaces or in addition to the color attached to the target region, and at least the lightness, hue, and saturation of the color attached to the region adjacent to the target region. Any one of them may be changed.

Next, the next generation candidate image generation unit 193 performs coloring on the target region (step S307). After step S306, or when it is determined in step S305 that the color is different from the color assigned to the area adjacent to the target area (step S305: NO), the process proceeds to step S307.
After step S307, the next generation candidate image generation unit 193 performs a termination process of the loop L22 (step S308). Specifically, the next generation candidate image generation unit 193 determines whether or not the process of the loop L22 has been performed on all the regions included in the template image. If it is determined that there is an unprocessed area, the process returns to step S303, and the process of the loop L22 is subsequently executed for the unprocessed area. On the other hand, when it is determined that the processing of the loop L22 has been performed on all the regions included in the template image, the loop L22 is terminated.

When the loop L22 is completed in step S308, the next generation candidate image generation unit 193 performs a termination process of the loop L21 (step S309). Specifically, the next generation candidate image generation unit 193 determines whether or not a predetermined number of candidate images have been generated. For example, in the case of the example described with reference to FIGS. 6 to 9, the next generation candidate image generation unit 193 determines whether or not six candidate images have been generated as indicated by the area A <b> 32 in FIG. 8. .
If it is determined that the planned number of candidate images has not been generated, the process returns to step S301 to continue generating candidate images. On the other hand, when it is determined that the planned number of candidate images has been generated, the loop L21 is terminated.
When the loop L21 is terminated in step S309, the process of FIG. 12 is terminated.

In the process of FIG. 12 (that is, crossover), when the same candidate image as the already presented candidate image is obtained, the display unit 110 may display the candidate image again. Or you may make it suppress the display of the said candidate image by the display part 110. FIG.
Alternatively, in step S302, the similar color arrangement acquisition unit 192 always acquires color arrangement information different from the selected color arrangement information, so that the same candidate as the candidate image already presented by the next generation candidate image generation unit 193 is obtained. You may make it suppress the production | generation of an image.
In the process of FIG. 12, the next generation candidate image generation unit 193 generates a candidate image having the same color scheme as the candidate image selected in step S106 of FIG. It may be possible to do this.

  The process performed by the next generation candidate image generation unit 193 in step S114 in FIG. 10 (that is, the mutation process) is the same as the process performed by the initial candidate image generation unit 191 in FIG. 11 except for the number of candidate images to be generated. Yes, illustration and description of the flowchart are omitted. The next-generation candidate image generation unit 193 performs the process of the loop L11 until it generates candidate images with a predetermined number of mutations. For example, in the case of the example described with reference to FIGS. 6 to 9, the next generation candidate image generation unit 193 generates three candidate images as shown in the area A <b> 33 of FIG. 8 in step S <b> 209 of FIG. 11. Determine whether or not. Note that the method for generating candidate images by mutation need not be the same as the method for generating candidate images in the initial candidate image generating unit 191, and is not particularly limited. The squaring method, mixed congruential method, linear feedback shift register , Mersenne Twister, or random parameters obtained using chaos random numbers or the like can be used. The parameters here correspond to each color arrangement information. If the parameters are determined, specific color arrangement information is determined (selected).

In addition, when the same candidate image as the already presented candidate image is obtained in the mutation, the display unit 110 may display the candidate image again. Or you may make it suppress the display of the said candidate image by the display part 110. FIG.
Alternatively, the next generation candidate image generation unit 193 may acquire color arrangement information that is different from the already selected color arrangement information, thereby suppressing generation of the same candidate image as the already presented candidate image. .

As described above, the initial candidate image generation unit 191 generates a candidate image in which a template image is colored based on the color scheme indicated by the color scheme information for each of a plurality of color scheme information included in the color scheme sample.
The initial candidate image generation unit 191 can generate a candidate image based on the color scheme indicated by the color scheme information included in the color scheme sample, thereby generating a candidate image having harmony of the color scheme.
Further, the similar color arrangement acquisition unit 192 is similar in relation to the color arrangement information that is the basis of the candidate image selected by the selection operation among the plurality of candidate images based on a predetermined condition set as the similar condition. Acquires color scheme information that satisfies the conditions. Then, the next generation candidate image generation unit 193 generates a candidate image in which a color is added to the template image based on the color arrangement acquired by the similar color arrangement acquisition unit 192.
The next generation candidate image generation unit 193 generates a candidate image based on the color arrangement information that is similar to the color arrangement information that is the basis of the previous generation candidate image, and thus is similar to the previous generation candidate image. Candidate images with harmonious color schemes can be generated.
As described above, the color arrangement support device 100 can generate a candidate image that is harmonious with the color arrangement, and can thereby support a person who is not a design expert to perform a harmonious color arrangement.

In addition, the similar color arrangement acquisition unit 192 includes color arrangement information indicating the color arrangement satisfying the similarity condition in relation to the color arrangement that is the basis of the candidate image selected by the selection operation among the plurality of candidate images in the color arrangement sample. Select from color scheme information. Then, the next generation candidate image generation unit 193 generates a candidate image in which a color is added to the template image based on the color scheme selected by the similar color scheme acquisition unit 192.
Thereby, the next-generation candidate image generation unit 193 can add a color to the template image based on the color arrangement information included in the color arrangement sample, and generate a candidate image that is harmonious with the color arrangement.

The similar color arrangement acquisition unit 192 may select color arrangement information from the color arrangement sample selected by the user. Alternatively, the similar color arrangement acquisition unit 192 may select color arrangement information from the entire color arrangement sample group.
When the similar color scheme acquisition unit 192 selects the color scheme information from the color scheme sample selected by the user, the user's preference indicated by the selection of the color scheme sample is reflected in the obtained candidate image even when the generation advances. Can do.
On the other hand, when the similar color arrangement acquisition unit 192 selects color arrangement information from the entire color arrangement sample group, the color arrangement support apparatus 100 can present more various candidate images.

Further, the next generation candidate image generation unit 193 generates a candidate image in which the template image is colored based on the color scheme indicated by the color scheme information randomly selected from the color scheme sample.
As described above, the next-generation candidate image generation unit 193 can perform mutation based on the color arrangement information included in the color arrangement sample, and generate a candidate image that is harmonious with the color arrangement. In addition, the next generation candidate image generation unit 193 executes the mutation, so that it is possible to propose a color scheme that the user cannot come up with. In this respect, the range of the color scheme can be widened.

Note that the next generation candidate image generation unit 193 may perform mutation by selecting color arrangement information randomly from the color arrangement sample selected by the user. Alternatively, the next generation candidate image generation unit 193 may perform mutation by selecting color arrangement information at random from the entire color arrangement sample group.
When the next-generation candidate image generation unit 193 performs mutation by randomly selecting color scheme information from the color scheme sample selected by the user, the candidate image obtained by the mutation is indicated by the selection of the color scheme sample. User preferences can be reflected.
On the other hand, when the next generation candidate image generation unit 193 performs mutation by selecting color arrangement information randomly from the entire color arrangement sample group, the color arrangement support apparatus 100 proposes a color arrangement that the user cannot come up with in a wider range. And the width of the color scheme can be further expanded.

In addition, the next generation candidate image generation unit 193 adds different colors to adjacent areas among the areas included in the template image.
Here, it is considered that the user intends to change the color for each area when specifying the area of the template image. The next-generation candidate image generation unit 193 can generate a candidate image that more reflects the user's intention by adding different colors to adjacent regions among the regions included in the template image.

Further, when the next generation candidate image generation unit 193 determines that the colors assigned to the adjacent regions among the regions included in the template image are the same, the next-generation candidate image generation unit 193 attaches a color with a changed brightness to at least one of the adjacent regions. With a different color.
Thereby, even when the number of colors indicated by the color arrangement information is limited, the next-generation candidate image generation unit 193 can add different colors to the colors of the adjacent regions, and the candidate more reflects the user's intention. An image can be generated.

In addition, the next generation candidate image generation unit 193 adds colors in order from an area included in the template image in which the number of adjacent areas is large.
As a result, when the next generation candidate image generation unit 193 adds a color to an area having a large number of adjacent areas, the number of areas already colored among the adjacent areas is relatively small, and the color can be freely added. The degree is great. In this regard, the next-generation candidate image generation unit 193 can perform a process of adding a color relatively easily.

As described above, five people (design non-experts) use the color arrangement support device 100 that stores color arrangement samples in advance and the conventional color arrangement support device that does not store color arrangement samples in advance. The following results were obtained when a five-point evaluation questionnaire was conducted. In addition, 5 points have the highest evaluation and 1 point has the lowest evaluation.
Regarding the aesthetic satisfaction, in the conventional color arrangement support device, 5 points are 0 people, 4 points are 1 person, 3 points are 2 people, 2 points are 2 people, 1 point is 0 people.
On the other hand, in the color arrangement support apparatus 100, 5 points are 0 people, 4 points are 2 people, 3 points are 2 people, 2 points are 1 person, 1 point is 0 people.
In this way, the color arrangement support device 100 has a slightly higher evaluation for aesthetic satisfaction than the conventional color arrangement support device.
In the questionnaire, there was an opinion that the color arrangement support device 100 suggested a color arrangement that could not be conceived by oneself.

Further, regarding the ease of work, in the conventional color arrangement support device, 5 points are 0 people, 4 points are 1 person, 3 points are 2 people, 2 points are 2 people, 1 point is 0 people.
On the other hand, in the color arrangement support apparatus 100, 5 points are 1 person, 4 points are 2 persons, 3 points are 2 persons, 2 points are 0 persons, 1 point is 0 person.
As described above, the color arrangement support apparatus 100 was highly evaluated for ease of work than the conventional color arrangement support apparatus.

In addition, when asked which is more satisfactory color scheme, there were 0 people who answered that the conventional color scheme support device, three people who answered that neither could be said, and the color scheme support device of this embodiment There were two people, and the color arrangement support device 100 was highly evaluated.
In addition, when asked which is easier to work, there were 0 people who answered that the conventional color arrangement support device, 0 people who could not say either, and those who answered the color arrangement support device of this embodiment. There were five people, and the color arrangement support apparatus 100 was highly evaluated.

Note that the user may be able to specify a color for at least one region of the template image. For example, the user may specify a collar color in the template image illustrated in FIG.
In this case, the initial candidate image generation unit 191 selects color arrangement information indicating a color arrangement including the designated color. For example, when the user designates the collar color as red, the initial candidate image generation unit 191 selects color arrangement information indicating a color arrangement including red. Then, the initial candidate image generation unit 191 attaches the designated color to the designated area, and colors the other areas as described above. For example, when the user designates the color of the collar as red, the initial candidate image generation unit 191 changes the color of the collar portion to red.

  Similarly, the similar color arrangement acquisition unit 192 selects color arrangement information indicating a color arrangement including the designated color. For example, when the user designates the color of the collar as red, the similar color arrangement acquisition unit 192 selects color arrangement information indicating a color arrangement including red. Then, the next generation candidate image generation unit 193 assigns the designated color to the designated area, and colors the other areas as described above. For example, when the user designates the collar color as red, the next-generation candidate image generation unit 193 changes the color of the collar portion to red.

As described above, when the color of at least one of the regions included in the template image is specified, the next generation candidate image generation unit 193 specifies the specified color among the color schemes indicated by the color scheme information included in the color scheme sample. A template image is colored on the basis of a color scheme including, and a designated color is given to a designated area to generate a candidate image.
Accordingly, the user can specify a favorite color, and the time required for the color arrangement support apparatus 100 to generate a candidate image that the user likes can be shortened.

Alternatively, the user may be able to specify a color or color scheme separately from the template image area.
When the user designates a color, the initial candidate image generation unit 191 generates a first generation candidate image based on color arrangement information indicating a color arrangement including the designated color. In addition, the similar color arrangement acquisition unit 192 selects color arrangement information indicating a color arrangement including the designated color, and the next generation candidate image generation unit 193 uses the crossover candidates based on the color arrangement information selected by the similar color arrangement acquisition unit 192. Generate an image.
When the user specifies a color scheme, the initial candidate image generation unit 191 generates a first generation candidate image based on the color scheme information that satisfies the similarity condition with the color scheme information indicating the designated color scheme. In addition, the similar color scheme acquisition unit 192 selects color scheme information satisfying the similarity condition in relation to the color scheme information indicating the designated color scheme, and the next generation candidate image generation unit 193 selects the color scheme information selected by the similar color scheme acquisition unit 192. Based on the above, a candidate image by crossover is generated.
Thereby, the user can specify a favorite color or color scheme, and the time required for the color scheme support apparatus 100 to generate a candidate image that the user likes can be further shortened.

Alternatively, the user may be able to make a rough designation regarding the color, such as a red color or a blue color.
For example, in addition to the classification described with reference to FIG. 4, the color arrangement information storage unit stores information including items of major classification. In the large classification item, information of a classification that is more general than the “classification” item, such as “red system” and “blue system”, is stored. Then, the initial candidate image generation unit 191, the similar color arrangement acquisition unit 192, and the next generation candidate image generation unit 193 select the color arrangement information included in the designated major classification when selecting the color arrangement information.
Accordingly, the user can specify his / her favorite color even when the detailed preference is not determined, and the time required for the color arrangement support device 100 to generate a candidate image that the user likes can be shortened.

It should be noted that a program for realizing all or part of the functions of the control unit 190 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. You may perform the process of. Here, the “computer system” includes an OS and hardware such as peripheral devices.
Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, and a flash memory, and a storage device such as a hard disk built in the computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
