Description

  The present invention relates to a color arrangement support device, a color arrangement support method, and a color arrangement support program.

In recent years, with the spread of graphic tools, it has become easier for ordinary people to design color schemes for web pages and the like using a personal computer. However, the color scheme of ordinary people is often not advanced, and when a typical color scheme is adopted, the design becomes uniform and the user's preference and personality cannot be reflected.
Therefore, Patent Document 1 describes a color arrangement method that can reflect user preferences and individuality. Non-Patent Document 1 proposes a system for designing a web page color scheme using interactive evolutionary computation as a color scheme that reflects user preferences and personality. This allows the user to select a favorite image from a plurality of images created based on the genetic algorithm, creates a plurality of images based on the genetic algorithm from the selected image, and further selects the user's favorite image. By repeating the selection of an image, the system performs an optimal color scheme design in consideration of user preferences.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an example of a candidate image designation / selection screen of the color arrangement support device 10 according to the first embodiment of the present invention.
The color arrangement support device 10 generates a plurality of candidate images having different color arrangements, and determines the color arrangement of the images by causing the user to designate the candidate images. This figure shows nine candidate images a1 to a9 displayed on the display unit by the color arrangement support device 10.
In FIG. 1, the corresponding color arrangement regions of the nine candidate images a1 to a9 have a color arrangement in which the color information of the color elements indicating brightness is the same. Here, in the color element indicating brightness, a bright color has high attractiveness, and a dark (not bright) color has low attractiveness.
In other words, the candidate images a1 to a9 are the same images in a portion having a high attractiveness and a portion having a low attractiveness.

If the candidate image displayed on the candidate image designation / selection screen includes an image for determining the color scheme, the user of the color scheme assistance apparatus 10 designates the image.
On the other hand, if the candidate image displayed on the candidate image designation / selection screen does not have an image for determining the color arrangement, the user of the color arrangement support apparatus 10 selects a favorite image from the candidate images. The color arrangement support device 10 generates a new candidate image from the selected image based on a genetic algorithm (GA) and displays it on the candidate image designation / selection screen.
Then, the user of the color arrangement support device 10 makes the same designation or selection, and the color arrangement support device 10 repeats generation of the same candidate image. In this way, the user of the color arrangement support device 10 finally designates a candidate image and determines the design based on the color arrangement of the image.

Here, in the present embodiment, colors are expressed using an HLS (Hue Luminance Saturation) color space, that is, hue, luminance, and saturation (color elements).
The luminance represents the brightness of the color, and takes a value of 0% to 100% in the HLS color space. The brightness approaches white as it approaches 100%, and the color becomes brighter. As the brightness approaches 0%, it approaches black and the color becomes darker. In general, in a design such as a web, the luminance is often set to be high for a portion that is desired to be conspicuous, and the luminance is set to be low for a portion that is not desired to be conspicuous.
For example, when generating candidate images, by maintaining the brightness, it is possible to maintain the intention of the user who wants to emphasize the color scheme of the basic image, reflecting the user's preference and personality can do.

The hue represents the type of color and takes a value of 0 to 360 degrees associated with an angle in the HLS color space. Values of 0 to 360 degrees in hue HLS space are associated with colors such as red, blue, and yellow. Note that the hue is expressed using an angle in the HLS space.
Saturation represents the vividness of the color, and takes a value of 0% to 100% in the HLS color space. Saturation indicates that the color becomes brighter as it approaches 100%, and the color becomes less vivid (dull or blurred) as it approaches 0%.

The color arrangement support device 10 maintains the color information (hereinafter referred to as maintenance color element information) determined by the user for the maintenance color elements that are part of the color elements of the candidate image, and the new candidate image. Is generated.
In the present embodiment, the maintenance color element is luminance as a color element indicating brightness. However, the present invention is not limited to this. For example, the maintenance color element may be a combination of luminance and saturation, luminance and hue, and luminance, saturation, and hue.
Also, the brightness of the HLS color space and the brightness of the HSV color space can be associated with each other. That is, maintaining brightness is equivalent to maintaining brightness.

FIG. 2 is a schematic configuration diagram illustrating the configuration of the color arrangement support device 10 according to the present embodiment.
2, the color arrangement support device 10 includes a use color information storage unit 100, a basic image input unit 101, a basic image information storage unit 102, a basic image group maintenance unit 103, an image group generation unit 104, an image designation unit 105, an image A selection unit 106 is included.

  The use color information storage unit 100 stores a plurality of highly independent colors (hereinafter referred to as color palettes) obtained by combining discrete values selected in advance with regard to hue, saturation, and luminance. That is, the use color information storage unit 100 stores information on a color selected in advance and having high independence as use color information.

For example, the hues of the color palette are 0 degree, 30 degrees, 45 degrees, 60 degrees, 65 degrees, 90 degrees, 150 degrees, 180 degrees, 210 degrees, 270 degrees, 285 degrees, and 333 degrees.
If a hue having a constant value (angle) difference is selected as a hue to be used as color information of the color palette, the bluish color increases. Therefore, the above-mentioned 12 hues are selected as hues that are easy to distinguish, that is, hues of highly independent colors.

The basic image input unit 101 inputs the basic image (FIG. 3) for which the maintenance color element information is determined by the user to the color arrangement support device 10.
Here, the basic image input by the basic image input unit 101 is, for example, an image in which a color scheme is applied to a web page, and is an image in which a user of the color scheme supporting apparatus 10 has previously performed a rough color scheme. The rough color scheme means, for example, a color scheme in which the luminance is increased by increasing the luminance of a portion to be conspicuous and lowering the luminance of a portion not desired to be conspicuous.

  For example, the basic image input unit 101 causes the user to create a design as a collection of regions (color arrangement regions) to be colorized from now on, and the use color information storage unit 100 stores the color of each color arrangement region of the design. Image data of a basic image is created by selecting from the use colors of the color information, and this is input to the color arrangement support device 10.

  Further, for example, the basic image input unit 101 reads the data of the current image selected by the user, and detects a region arranged in the same color included in the image. The basic image input unit 101 may input image data of a basic image by reading the color information of the detected area as a color arrangement area.

The basic image information storage unit 102 stores image data of a basic image.
Specifically, the basic image information storage unit 102 stores position information of each color arrangement area of the basic image and color information (FIG. 4) of the color arrangement area. There may be a plurality of basic images.

  Here, the maintenance color element information of the basic image stored in the basic image information storage unit 102 is also maintained in the generated candidate image, as will be described later. That is, the maintenance color element information storage unit 1021 stores the color information determined by the user for the maintenance color element of the candidate image.

The basic image group maintaining unit 103 generates a new candidate image while maintaining the position information of each color arrangement area and the maintenance color element information of the color arrangement area in the image data of the basic image.
Here, the basic image group maintenance unit 103 generates a new candidate image while maintaining the maintenance color element information stored in the basic image information storage unit 102 in the intersection image generation unit 1042 and the mutant image generation unit 1043. Let Details of the generation processing of the intersection image generation unit 1042 and the mutant image generation unit 1043 will be described later.

The image group generation unit 104 first generates a plurality of initial candidate images while maintaining the maintenance color element information of the basic image stored in the basic image information storage unit 102. Here, the image group generation unit 104 uses the color information randomly selected from the color palette stored in the usage color information storage unit 100 for the usage color information (hue and saturation) other than the maintenance color element (luminance) of the basic image. The initial candidate image is generated by changing the hue and saturation of the color information.
Note that the initial candidate image may be generated from the basic image by the intersecting image generation unit 1042 and the mutation image generation unit 1043. The plurality of initial candidate images may include a basic image.

  The image group generation unit 104 includes an image group storage unit 1041, a cross image generation unit 1042, and a mutant image generation unit 1043.

The image group storage unit 1041 stores image data of some images selected by the image selection unit 106 described later. Note that the image data of some of the images selected by the image selection unit 106 is N pieces of image data that is equal to or less than the number K of candidate images.
Note that N may be a different value for each selection performed by the image selection unit 106 that is repeatedly performed. The number K of candidate images is a predetermined value.

  The image group storage unit 1041 stores the image data of the initial candidate image generated by the image group generation unit 104. The image group storage unit 1041 stores image data of candidate images generated by the intersection image generation unit 1042 and the mutant image generation unit 1043. Here, the image data of the initial candidate image and the image data of the candidate image generated by the cross image generation unit 1042 and the mutation image generation unit 1043 are K pieces of image data.

The intersection image generation unit 1042 and the mutation image generation unit 1043 generate image data of K candidate images from the N image data selected by the image selection unit 106.
Note that the image data generated by the intersection image generation unit 1042 and the mutant image generation unit 1043 may include N pieces of image data selected by the image selection unit 106. For example, when K = 9 and N = 3, the intersecting image generation unit 1042 generates four image data, the mutant image generation unit 1043 generates two image data, and the generated image data, The three image data selected by the image selection unit 106 may be combined into image data of nine candidate images.

The intersection image generation unit 1042 combines the color information of the image data stored in the image group storage unit 1041 and generates a new candidate image of the combined color information.
For example, for the candidate image selected by the image selection unit 106 stored in the image group storage unit 1041, the intersecting image generation unit 1042 obtains color information of a color arrangement region that is at least a partial area of the image and performs color arrangement. Then, the candidate image is generated by changing to the color information of the corresponding color arrangement region of the other candidate image selected by the image selection unit 106.
Details of processing performed by the intersection image generation unit 1042 will be described later.

The mutant image generation unit 1043 changes the color information of the image data stored in the image group storage unit 1041, and generates a new candidate image of the changed color information.
Specifically, the mutant image generation unit 1043 converts a part of the color information to be changed in each color arrangement region of the candidate image selected by the image selection unit 106 stored in the image group storage unit 1041 to the color information to be changed. The candidate image is generated by changing while maintaining some of the interrelationships.
Details of processing performed by the mutant image generation unit 1043 will be described later.

The process of the intersection image generation unit 1042 corresponds to the intersection of the gene algorithm, and the process of the mutation image generation unit 1043 corresponds to the mutation of the gene algorithm.
In addition, the color arrangement support device 10 causes the user to select a candidate image using the image selection unit 106, and performs processing of the cross image generation unit 1042 and generation of a mutant image for a part (N images) of the selected image. Based on the interactive genetic algorithm, a new candidate image (K images) is generated by the processing of the unit 1043, and the user is allowed to select a candidate image by the image selection unit 106. Provide color support.

The image designation unit 105 and the image selection unit 106 display the K candidate images generated by the image group generation unit 104 and stored in the image group storage unit 1041 on the display 20 (candidate image designation / selection screen, FIG. 1).
If the displayed candidate images include candidate images for determining the color scheme, the user designates the candidate images using the input device 21. That is, the image designation unit 105 causes the user to designate an image for which the user determines the color scheme among the candidate images generated by the image group generation unit 104.

On the other hand, if the displayed plurality of candidate images do not include an image for determining a color scheme, the user uses the input device 21 to select some of the plurality of candidate images (N images). select. That is, the image selection unit 106 causes the user to select some of the candidate images generated by the image group generation unit 104.
Details of processing performed by the image selection unit 106 will be described later.
Further, the image selection unit 106 causes the image group storage unit 1041 to store image data of a part of images selected by the user.

The used color information storage unit 100 and the basic image information storage unit 102 hold data, and are realized using a magnetic hard disk device or a semiconductor memory.
Further, the basic image input unit 101, the image group generation unit 104, the image designation unit 105, and the image selection unit 106 are realized by the color arrangement support apparatus 10 reading out and executing a program held in the recording medium or by an electronic circuit. Is done.

Hereinafter, details of processing performed by the image group generation unit 104 and the image selection unit 106 will be described.
First, the basic image will be described.
FIG. 3 is a diagram illustrating an example of a basic image according to the present embodiment. In this figure, the basic image includes color arrangement regions a111, a121, a122, a131 to a136, a141, and a151 to a153.
Here, it is assumed that a121, a122, a131 to a136, and a151 to a153 are arranged in the same color.
Hereinafter, in the basic image and the candidate image, the color arrangement area corresponding to a111 is referred to as color arrangement area 1, the color arrangement area corresponding to a121 and a122 is referred to as color arrangement area 2, and the color arrangement area corresponding to a131 to a136 is referred to as color arrangement area 3. , A color arrangement area corresponding to a141 is referred to as color arrangement area 4, color arrangement area 5 corresponding to a151 to a153.

  FIG. 4 is a diagram illustrating an example of image data of a basic image according to the present embodiment. Here, it is assumed that the basic image is the image a1 (FIG. 1).

In the present embodiment, as described above, the hue of the color arrangement area included in the basic image is assumed to be 12 predetermined hues.
In FIG. 4, 12 hues are associated with values of 0 to 11 as hue values. For example, the hue value “1” is associated with “60” degrees in the HLS color space and indicates yellow.

For example, in FIG. 4, the “color arrangement area 1”, that is, the color arrangement area a111 in FIG. 3, has a luminance of “20”% and a hue of “1”, that is, a hue of 60 degrees and a saturation of “10”%. It represents something.
The value of the HLS color space can be converted into a value of each color space of RGB (Red Green Blue), CMYK (Cyan Magenta Yellow Keytone), and HSV (Hue Luminance Saturation).

Next, processing performed by the image selection unit 106 will be described.
The image selection unit 106 displays the candidate images (for example, K = 9 images) generated by the image group generation unit 104 on the display 20 (candidate image designation / selection screen, FIG. 1).

If the displayed candidate image includes a candidate image for determining a color arrangement, the user designates the candidate image using the input device 21. For example, in FIG. 1, the user likes the color scheme of the image a <b> 2 and specifies the image a <b> 2 using the input device 21 when determining the color scheme as the image a <b> 2.
On the other hand, if there is no candidate image for determining the color arrangement in the displayed candidate image, the user selects a part of the candidate images using the input device 21. For example, in FIG. 1, the user does not have to decide the color scheme, but when the user likes the image a1, the image a2, and the image a9, the image a1, the image a2, and the image a9 ( N = 3 images).

Next, the intersection process performed by the intersection image generation unit 1042 will be described.
FIG. 5 is a diagram for explaining the intersection processing according to the present embodiment.
In this figure, an image a1, an image a2, and an image a9 are assumed to be screens selected by the image selection unit 106. The image b1 and the image b2 are images generated by performing the intersection process.
The color arrangement area a13 of the image a1, the color arrangement area a23 of the image a2, the color arrangement area a93 of the image a9, the color arrangement area b13 of the image b1, and the color arrangement area b23 of the image b2 are the color arrangement area 3. The color arrangement area a15 of the image a1, the color arrangement area a25 of the image a2, the color arrangement area a95 of the image a9, the color arrangement area b15 of the image b1, and the color arrangement area b25 of the image b2 are the color arrangement area 5.

Further, in the present embodiment, the intersection process is at least a partial area of the candidate image selected by the image selection unit 106, and the color information of the color arrangement region to be subjected to the color combination is selected by the image selection unit 106. The candidate image is changed to the color information of the corresponding color arrangement region of the candidate image to generate a new candidate image.
It is assumed that the image to be subjected to the intersection process, the image intersected with the image, and the color scheme area to be changed are selected at random.

In FIG. 5, the image b1 is an image generated by the intersection image generation unit 1042 by changing the color of the color arrangement area 3 (a13) of the image a1 to the color of the corresponding color arrangement area 3 (a23) of the image a2, that is, Represents an image generated by the intersection processing.
In the present invention, for example, like the image b2 in FIG. 5, the color of the color arrangement region 5 (b15) of the image b1 generated by the intersection image generation unit 1042 by the intersection processing is changed to the corresponding color arrangement region 5 of the image a9. The image may be generated by changing to the color (a95) and generated by the intersection process.

FIG. 6 is a diagram illustrating an example of color arrangement data of an image subjected to the intersection process by the intersection image generation unit 1042 according to the present embodiment.
Here, FIG. 6 shows color arrangement data of the image b2 (FIG. 5) obtained by performing the intersection process on the image a1.
Comparing FIG. 6 and FIG. 4, the luminance value does not change, and the hue and saturation of the color arrangement region 3 and the color arrangement region 5 are changed. That is, the basic image group maintenance unit 103 causes the intersection image generation unit 1042 to generate new candidate images while maintaining the maintenance color element information (luminance information) stored in the basic image information storage unit 101.
For example, in FIG. 6, the “color arrangement area 3”, that is, the color arrangement area a13 in FIG. 5, has a luminance of “80”%, a hue of “6” (for example, a hue of 180 degrees), and a saturation of “60”%. It represents that.

Next, the mutation process performed by the mutation image generation unit 1043 will be described.
FIG. 7 is a diagram for explaining the mutation process according to the present embodiment.
In this figure, an image a1 is a screen selected by the image selection unit 106. The image b3 is an image generated by performing a mutation process on the image a1.

In the present embodiment, the mutation process refers to a part or all of the color information to be changed in each color arrangement region of the candidate image selected by the image selection unit 106, and a part or all of the color information to be changed. It means that a new candidate image is generated by changing while maintaining the relationship.
In FIG. 7, the image b <b> 3 is an image that is changed while maintaining the mutual relationship between the hues of the color arrangement area 1 to the color arrangement area 5 of the image a <b> 1. That is, the correlation between the hues of the color arrangement area a11 to the color arrangement area a15 of the image a1 and the correlation of the hues of the color arrangement area b31 to the color arrangement area b35 of the image b3 are the same.
Specifically, the mutant image generation unit 1043 converts the hue represented by Expression (1) as represented by Expression (2).

Here, k indicates a color arrangement area (color arrangement area 1 to color arrangement area 5). C (k) represents the hue of the HLS space of the color arrangement region k, and n represents a value (0 to 11) corresponding to 12 hues of the predetermined use color.
Expression (2) means that C (k) is converted into a remainder obtained by dividing C (k) + m by 12. Note that m is a value common to all k.
Note that the mutant image generation unit 1043 randomly selects and changes the saturation of the color palette stored in the use color information storage unit 100 for the saturation.

In the present embodiment, with regard to the mutation process, the color scheme is changed while maintaining the difference in value as the 12 hues determined in advance. However, the present invention is not limited to this, for example, the HLS space of each color scheme area. The color arrangement may be changed while maintaining the difference in the values (0 to 360 degrees), that is, the angle difference.
In this case, the image group generation unit 104 converts the hue as shown in Expression (3).

  Here, k indicates a color arrangement area (color arrangement area 1 to color arrangement area 5). A (k) indicates the hue value (angle) of the HLS space of the color arrangement region k, and φ is an arbitrary angle of the hue of the HLS space. Equation (3) means that A (k) is converted into a remainder obtained by dividing A (k) + φ by 360.

FIG. 8 is a diagram illustrating an example of color arrangement data of an image subjected to mutation processing by the mutation image generation unit 1043 according to the present embodiment.
Here, FIG. 8 shows color arrangement data of the image b3 (FIG. 7) obtained by performing the intersection process on the image a1.
Comparing FIG. 8 with FIG. 4, the luminance value does not change, and the hue is changed while maintaining the difference in value from each color arrangement region. That is, the basic image group maintenance unit 103 causes the mutant image generation unit 1043 to generate new candidate images while maintaining the maintenance color element information (luminance information) stored in the basic image information storage unit 102. .
For example, in FIG. 8, the “color arrangement area 3”, that is, the color arrangement area b33 in FIG. 7, has a luminance of “80”%, a hue of “5” (for example, a hue of 150 degrees), and a saturation of “60”%. It represents that.

FIG. 9 is a flowchart showing the operation according to the present embodiment.
The user creates a basic image by coloring the image (S101).
The basic image information storage unit 102 stores the image data of the basic image (S102).
The image group generation unit 104 generates an initial candidate image while maintaining the maintenance color element information (luminance information) of the basic image (S103).

The image designation unit 105 and the image selection unit 106 display the candidate images generated by the image group generation unit 104 on the display 20 (S104).
The image designating unit 105 determines whether a candidate image for determining a color scheme has been designated (S105).
When a candidate image whose color scheme is to be determined is designated in S105, the image designating unit 105 determines a color scheme based on the color scheme of the designated candidate image (S109).

On the other hand, when the candidate image for determining the color arrangement is not designated in S105, the image selection unit 106 selects a part of the candidate images (S106).
Next, the intersection image generation unit 1042 performs intersection processing on a part of the images selected by the image selection unit 106 to generate a new candidate image (S107).
Next, the mutation image generation unit 1043 performs a mutation process on a part of the images selected by the image selection unit 106 to generate a new candidate image (S108).
Next, the color arrangement support device 10 proceeds to the process of S104.

  As described above, the color arrangement support device 10 repeats the selection process by the image selection unit 106, the cross process and the mutation process by the cross image generation unit 1042 and the mutant image generation unit 1043, that is, the color arrangement by interactive evolution calculation. Support the design.

Thus, according to the present embodiment, the color arrangement support device 10 is selected by the user while maintaining the maintenance color element information determined by the user for a part (luminance) of the color elements of the candidate image. The color information of some of the images is combined or the color information is changed to generate a new candidate image.
As a result, the portion that the user wants to stand out is high, the portion that does not want to stand out is low, and the candidate image whose brightness is different from the basic image is not generated, and the probability that the color scheme desired by the user increases, The number of repetitions in the interactive calculation can be suppressed, and an image with a color scheme desired by the user can be provided at an early stage.

In the field of design, it is recommended to use colors with a difference in brightness (lightness) so that persons with color blindness can easily identify the display. For example, W3C (World Wide Web Consortium) provides a guideline for setting a luminance difference between a foreground color and a background color to be a certain level or more.
According to the present embodiment, the color arrangement support device 10 generates the candidate image while maintaining the color information of the luminance determined by the user, and therefore can provide an image with the luminance difference maintained. .

  Further, since the color information of the candidate image is the color information selected from the use color information, the color arrangement support apparatus 10 does not generate a candidate image of other color information, and the color arrangement desired by the user can be obtained earlier. Provided images can be provided. Furthermore, since the color information of the candidate image is color information selected from the use color information, the color arrangement support device 10 does not generate a candidate image of color information with low independence, and the user desires earlier. An image with a color scheme can be provided.
