Description

The present invention relates to a technique for changing the color scheme of an image that is a display object on a display using a computer, and relates to a color scheme simulation system that is optimal for a user to efficiently perform intuitive and detailed color scheme design. Is.

  Conventionally, color schemes by various colorologists have been proposed for color schemes, and there are examples of color schemes based on them (Non-Patent Document 1).

  Further, a method has been proposed in which a color scheme corresponding to an image of a main adjective is investigated and plotted on a two-dimensional image map based on a psychological axis (Non-patent Document 2).

  On the other hand, as a technique related to color arrangement design using a computer in recent years, there are, for example, an image changing technique corresponding to a language based on a color code and a color sensation (Patent Document 1), and a technique corresponding to a general emotion phrase related to a color arrangement (Patent Document 2). ). In addition, there is a technique that supports color arrangement based on the impression of an image using a sample image instead of an emotional phrase (Patent Document 3).

  However, it is difficult to apply or apply the color scheme theory in a specific life scene unless it is an expert skilled in color knowledge and design such as a color coordinator.

  This is because color is conventionally expressed as a three-dimensional concept based on hue, saturation, and lightness, which is said to be the three attributes of color. This is because it is roughly divided into tones (color tones) that are combinations of lightness, and it is very difficult to intuitively grasp these patterns.

  In particular, the tones are often two-dimensionally displayed by combining two attributes, brightness and saturation, but when the tone is represented by a color solid, it becomes a ring shape, and its features and forms can be imagined from the tone names. Difficult to do.

  According to the JIS standard (object color color name JIS Z 8102), the tone is “color range with modifiers for lightness and saturation of chromatic colors”. “N” “Bright” “Good” “Koi” “Light” “Soft” “Dull” “Dark” “Very light” “Bright ash” “Ashes” “Dark ash” “Very thin” There are 13 types. They are not represented in three dimensions, although color space regions are set for each hue.

  Also, since various color arrangement theories including tones are based on the assumption of two-dimensional display, the rules are simplified and it is difficult to create a complicated three-dimensional color arrangement pattern. For example, there are color rules that create geometric forms on the hue circle, such as triads (equilateral triangles), split complementarys (isosceles triangles), dyads (regular squares), etc. There is no high harmony, and there is a problem that if they are applied as they are, they cannot be differentiated in an era when there are many color variations like today.

  Further, when the color scheme proposed as a color scheme is to be adapted to various fields, there is a limitation on color variations and the like that exist depending on the field, so that it is necessary to make fine adjustments. For example, it may be difficult to make such fine adjustments while changing the balance of the three colors because the overall impression may be lost just by changing one of the three colors. There was a problem.

  Further, in the adjectives and color schemes described in Non-Patent Document 2, the three color schemes corresponding to the sensitivity words are disclosed, but since they are plotted in a plan view with two original psychological attributes, the color scheme pattern There was a problem that it was difficult to understand the distribution tendency in the color solid.

  In addition, the proposed patents have no relationship between color sense and emotion phrases and color solids, and images and color solids. There was a problem that adjustment could not be performed.

  In consideration of the above-described problems of the prior art, the present invention can efficiently perform intuitive and detailed color scheme design even for a user having no color scheme knowledge, and can perform simple and interactive simulation.

  According to the present invention, even a user who has no color scheme knowledge can efficiently perform an intuitive and detailed color scheme design, and can perform a simple and interactive simulation. It can be reduced.

  For example, when a designer changes the color scheme in an image in fashion, graphic, product, landscape, etc., the details according to the client's request can be changed by changing the color scheme corresponding to the sensitivity word on the color solid. As a result, it is possible to perform simple and interactive simulation even by a user who does not have a color scheme knowledge by selecting a sensitivity word, thereby greatly reducing the effort of selecting a color scheme.

In addition, for example, when a manufacturer develops a product that occupies an important element such as fashion or interior, or when a user selects a color combination, it is possible to check the combination of the color schemes in a color three-dimensional distribution. At the same time, it is possible to change the selected model image by changing one or a plurality of colors at the same time, so that a fine color arrangement can be adjusted. For example, if the basic color scheme is judged to be good, but the impression of the color scheme remains the same, making it a little brighter, brighter, or vibrant will change the color values. However, it is difficult to adjust or judge the degree, but the range bar that rotates the hue of the color solid, raises or lowers the brightness, scales the saturation, and scales the area created by the color scheme By manipulating it,
In addition, for example, by associating a color scheme pattern with a sensitivity word in advance, it is possible to select a color scheme pattern from an intuitive image and change the model image, and at the same time check the color scheme tendency of the sensitivity word from a color solid Become. As a result, it is possible to easily create a color arrangement pattern corresponding to a new sensitivity word. In addition, for example, by looking at the list of sensitivity words and color schemes, it is possible to intuitively understand what kind of sensitivity terms correspond to which color scheme, and selecting them allows you to select a model image. It can be changed in real time, and the effect that the impression and the sensitivity word of the changed model image can be confirmed is obtained.

  In addition, for example, a list of sensitivity words and color schemes cannot be confirmed at a time when the number of patterns becomes enormous, but it is similar by rearranging the color schemes from various numerical values obtained from the color scheme geometry. Can be seen in order of the sensibility tendency. For example, the area of a triangle formed by connecting three points of a three-color color scheme in a color solid has a tendency to give a more active impression as the size is larger. By rearranging in the order of “in descending order”, in terms of sensitivity words, “lively” color schemes, “active” color schemes, and “active” color schemes can be viewed in order. Therefore, an effect that the efficiency of color arrangement pattern selection can be improved is obtained.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an overall view of a color arrangement simulation system according to the present embodiment.

  The color scheme simulation system 10 can easily select a color variation of a product corresponding to a sensitivity word, for example, by setting a color scheme area of the product image characterized by the color and changing the color scheme of the color scheme area on the screen. It is a color scheme simulation system.

  Here, the color arrangement simulation system 10 includes a color arrangement simulation device 11, a communication network 12, and a plurality of user terminals 16 (possible).

  The color arrangement simulation apparatus 11 is a computer device having input / output means such as product model image data and character information necessary for rearrangement and search of color arrangement patterns. For example, a computer device having an interface connectable to devices such as a keyboard, a mouse, a USB memory, a digital camera, a scanner, a monitor, a television, and a printer can be used as the color arrangement simulation device 11.

  The color arrangement simulation apparatus 11 includes three databases, ie, a model image database 13 as a first database, a color arrangement pattern database 14 as a second database, and a color information database 15 as a third database. It may be dispersed. In that case, the color arrangement simulation apparatus 11 includes means for connecting and processing databases provided in different computers.

  Although not shown, the color arrangement simulation device 11 includes a communication control device that enables connection to a communication network.

  The model image database 13 stores a large amount of image data for searching for model image data and color arrangement areas and displaying them in a color solid.

  The color arrangement pattern database 14 accumulates color information constituting the color arrangement pattern list. For example, it includes information such as a sensitivity word name, a color value constituting a color arrangement pattern corresponding to the sensitivity word name, and an area occupied when the color value is plotted on a color solid.

  The color information database 15 stores various color information constituting the color solid for searching the image data and displaying it on the color solid. That is, color information such as color values and color differences necessary for displaying a color solid such as Munsell color system, L * A * B * color system, RGB color space, HSV color space, and HLS color space.

  The communication network 12 is a computer network that can connect the color arrangement simulation apparatus 11 (the model image database 13, the color arrangement pattern database 14, and the color information database 15) and the user terminal 16 to each other. The communication network 12 may be a local area network or a wide area network such as the Internet.

  The user terminal 16 is, for example, a terminal device provided with a network interface that can be connected to the communication network 12. It is optional and may be one or more. The user terminal 16 accesses the first to third databases provided in the color arrangement simulation device 11 via the communication network 12, searches the color arrangement region of the model image data provided in the color arrangement simulation device 11, and performs the color arrangement geometry. It is possible to acquire and view the result of the means for displaying in a color solid.

  FIG. 2 is an apparatus diagram when the color arrangement simulation system 100 according to the present embodiment is realized by a single computer.

  The color arrangement simulation system 100 includes an input device 101 as input means, an output device 102 as display means, a CPU 103, a main storage unit 104, and a bus 105.

  Further, the color arrangement simulation system 100 includes a search key input control unit 106, a rearrangement key input control unit 107, an image information input control unit 108, a color arrangement information input control unit 109, a color information input control unit 110, and an image data output control unit 111. And a control unit such as a color solid output control unit 112 and a color arrangement pattern output control unit 113.

  The color arrangement simulation system 100 is connected to a model image database 114, a color arrangement pattern database 115, and a color information database 116. FIG. 9 is a structural example of the color arrangement pattern database 115.

  Further, the color arrangement simulation system 100 includes a color arrangement area accumulation calculation unit 117, a color value change calculation unit 118, a color arrangement change calculation unit 119, a color arrangement geometry change calculation unit 120, a color arrangement pattern rearrangement calculation unit 121, and an image color analysis calculation unit. Computation units such as 122 are provided.

  FIG. 5 is an example of a user interface 300 in the present embodiment. The input device 101 serves as the input means described above, and the output device 102 serves as the display means. Reference numerals 301, 302, and 303 denote parts for displaying three color arrangement regions of the model image, reference numeral 304 denotes a part for displaying the model image, and reference numeral 305 denotes 3 of each sensitivity word when using about 1000 sensitivity words. 306 is an instruction unit for instructing a change in hue, lightness, saturation, and area with an increase / decrease key, and 307 is a specific example in the RGB color space, HSV color space, and Munsell color system. It is a part to input a numerical value. A portion 308 displays a Munsell color system color solid.

  As described above, the user interface 300 displays a model image and a color arrangement area of the model image, and has an area for displaying a color arrangement pattern list and a color solid in which the color arrangement geometry is displayed. In addition, controls for adjusting hue rotation, brightness up / down, saturation magnitude, and area size, which are color arrangement moving elements set to move the color arrangement geometry on the color solid, are arranged.

  A setting control for changing the type of color solid such as RGB, HSV, Munsell, etc. is also arranged.

  Next, an outline of the operation of the present embodiment will be described.

  FIG. 3 is a flowchart for creating a model image database in the present embodiment.

  The image input process (S101) is performed by causing the image information input control unit 108 to accumulate a signal output from the input device 101, that is, a digital image, in the model image database 114. It may be image data from a digital camera or image data from graphic drawing software.

  In the color arrangement area P selection process (S102), the color arrangement area of the input image data is selected. P takes a value from 1 to the maximum value of the color arrangement area, and in this embodiment, one color arrangement pattern is configured with three colors, and therefore the maximum value of the color arrangement area is set to 3.

  In the representative color calculation process (S103) of the color arrangement area P, all the color information of the selected color arrangement area is read, and the image color analysis calculation unit 122 analyzes the representative color to obtain representative color data. .

  In extracting representative colors, the image color analysis calculation unit 122 divides the RGB values of all the pixels in the color arrangement area selected by the color difference by R, G, and B by the parameters of all the pixels and averages them. Is used.

  In extracting the average color, the image color analysis calculation unit 122 uses a method in which the RGB values of all the pixels included in the image are divided by R, G, and B and are averaged and extracted. It is done.

  One value of P is added by the process of incrementing P (S104).

  It is determined whether or not P is smaller than the maximum value of the color arrangement area (S105). If it is smaller, the process repeats from the color arrangement area P selection process (S102).

  If P is larger than the maximum value of the color arrangement area, the model image data, the color arrangement area, and the representative color of each color arrangement area are stored in the model image database (S106). In the present embodiment, since the number of color arrangement regions is 3, data is accumulated when P becomes 4.

  FIG. 4 is a flowchart for changing the color arrangement region of the model image in the present embodiment.

  The user inputs a single sensitivity word from the input device 101 (S200), acquires the color value corresponding to the input sensitivity word from the color pattern database 115 (S201), and sets the color arrangement pattern in order from the acquired color value. The database 115 is rearranged based on the color value (S202).

  As the determination criteria in the close order, for example, input from the input device 101 whether the color arrangement geometry area (the area of a triangle formed by three representative colors on the color solid to be described later) is rearranged in ascending order or descending order Then, the color arrangement pattern database 115 is rearranged based on the area of the color arrangement geometry so as to be in the input order (S204).

  From the rearranged color arrangement pattern database 115, the user selects another color arrangement pattern that is more desirable (S205), and acquires the color value of the selected color arrangement pattern from the color arrangement pattern database 115 (S206).

  Alternatively, as a completely different method, the user inputs a hue change value more likely to be desired from the input device 101 (S207), inputs a brightness change value (# 208), and changes the saturation. A value may be input (S209).

  In this way, when a change instruction that seems to be desired is obtained, the process of moving the color arrangement geometry in the color solid (S210) is obtained by the process of (S200) to (S206) in the change method using the sensitivity word. The vertex of the color arrangement geometry displayed on the color solid is moved in accordance with the color value of the color arrangement pattern. Alternatively, in the case of changing with the changed values of hue, lightness, and saturation, the values are displayed on the color solid according to the changed values of hue, lightness, and saturation obtained by the processing from (S207) to (S209). Move the vertex of the color scheme geometry.

  In addition, the process (S211) of changing the color arrangement of the color arrangement area of the model image is performed with a color arrangement pattern corresponding to the newly formed color arrangement geometry after the movement of the color arrangement geometry on the color solid is completed. Change the color scheme of the color scheme area and display it.

  FIG. 6 is an example of changing the color arrangement geometry displayed on the color solid.

  Since this is an example of a Munsell color system color solid, changing the value of the hue of an arbitrary color arrangement is equivalent to rotating the coordinates of the arbitrary color arrangement horizontally with respect to the bottom surface on the color solid. Changing the value of lightness is equivalent to moving the coordinates of an arbitrary color scheme up and down on the color solid. Changing the saturation value is equivalent to enlarging or reducing the area of an arbitrary color arrangement on the color solid while maintaining the shape. The change from FIG. 6A to FIG. 6B is an example in the case where the hue is changed while the lightness and the saturation are kept as they are. The triangle formed by three representative colors is shown rotating.

  Next, the embodiment of the present invention will be described more specifically.

  Preparations are made for the model image in advance.

  A digital camera that has captured a model image is directly connected to the input device 101 of the color arrangement simulation system. Alternatively, an SD card connected from a digital camera may be connected. The target color arrangement region may be a monochrome document or design, or may already have a color in the image, such as a photo or illustration. In the present embodiment, the image information input control unit 108 reads a photograph of a man wearing dark brown slacks on a thin pink shirt and wearing black leather shoes.

  Next, the color value change calculation unit 118 is activated.

  To select a color arrangement region, click an arbitrary point on the model image with the mouse. The computer reads the color value of the clicked pixel, determines the same color range as the extracted color value based on the color tone level, and recognizes it as one color arrangement region. The number of color arrangement areas is selected as many as the number of color arrangement patterns. Here, since the color arrangement patterns are composed of three colors, color arrangement areas 1 to 3 are selected.

  First, the slack portion was selected as the color arrangement region 1. Since the dark brown was taken with only slacks taken, the entire slacks could be selected with a single mouse click. The result is displayed on the display portion 301 of the color arrangement area 1. At the same time, the color of the slack portion of the model image is displayed with the color value of one pixel.

  Next, a shirt portion was selected as the color arrangement region 2. Since the shadowed part is not selected, the color difference level based on the L: * a * b * color system is changed from ΔE0.5 to ΔE0.55. As a result, the computer recognized the shaded portion that was a little dark pink as the same color as the light pink of the shirt, and set the selected portion as the color arrangement region 2. It is also possible to enlarge or reduce the area using the cursor. The result is displayed on the display portion 302 of the color arrangement area 2. At the same time, the color of the slack portion of the model image is also displayed with the color value of one pixel.

  Next, a leather shoe portion was similarly selected as the color arrangement region 3. The result is displayed on the display portion 303 of the color arrangement area 3. At the same time, the color of the slack portion of the model image is also displayed with the color value of one pixel.

  A known technique can be used for specifying these color arrangement regions.

  Next, each representative color is calculated from each of the color arrangement regions 1, 2, and 3.

  In extracting representative colors, the image color analysis calculation unit 122 extracts the RGB values of all the pixels in each color arrangement area selected based on the color difference by dividing the R, G, and B by the parameters of all the pixels and averaging them. Etc. are used.

  In this way, the error is adjusted so that the impression of the representative color felt by human senses and the impression of the representative color automatically extracted do not change. Note that other representative color calculation methods may be used.

  Next, the representative colors of the calculated color arrangement regions 1 to 3 are displayed in the color solid as follows.

  The color solid itself corresponds to any of the Munsell color system, L * a * b * color system, RGB color space, HSV color space, or HLS color space selected by the color value change calculation unit 118 on the screen. The read color value is read from the color information database 116, and the color solid output control unit 112 displays it on the color solid display portion 308 of the screen. The color value change calculation unit 118 converts each representative color of the color arrangement regions 1 to 3 into a color value corresponding to the selected color system. The color arrangement pattern output control unit 113 displays the representative color of each color arrangement area on the color solid with the converted color value.

  The color arrangement area accumulation calculation unit 117 links the calculated representative colors of the color arrangement areas 1 to 3, the color arrangement areas 1 to 3, and the model image, and accumulates them in the model image database.

  Next, the color arrangement pattern of the color arrangement area of the model image data prepared in this way is changed.

  First, a color scheme to be changed is selected from the display portion 305 of the color scheme list. In this color arrangement pattern list, sensitivity words of about 1000 words are arranged vertically, and three colors corresponding to each sensitivity word are arranged horizontally, and by further sorting, The order can be changed.

  Now, assume that “tasteful” is selected from the list of color schemes. The sensitivity word “tasteful” is composed of representative color 1 (R233, G228, B228), representative color 2 (R73, G44, B40), and representative color 3 (R2080, G106, B57). FIG. 9 shows an example of the structure of the color arrangement pattern database. The representative color 1 at the left end of this table is applied to the color arrangement area 1, the central representative color 2 is applied to the color arrangement area 2, and the representative color 3 at the right end is the color arrangement. This is applied to the area 3. It should be noted that an operation unit (not shown) for switching the application relationship may be provided in the user interface 300 so that it can be changed.

  Therefore, when “tasteful” is selected, the leftmost brown is the color of the slack selected in the color arrangement region 1 of the model image. Similarly, white at the center is the shirt color and dark brown is the color of leather shoes. The three color arrangement regions 301, 302, and 303 arranged in the left-right direction on the screen are changed in display with a “tasteful” color arrangement pattern. At the same time, the color of the display portion 304 of the model image is also changed correspondingly. Further, the three representative color triangles on the color solid display unit 308 also move correspondingly.

  Further, when it is desired to change to a sensitivity word slightly different from the sensitivity word “tasteful”, sorting is first performed in the display portion 305 of the color arrangement pattern list. In other words, the data of the three representative colors is calculated from the color scheme such as area, angle, brightness difference, saturation difference, hue difference, average hue, average brightness, average saturation, maximum interior angle difference, and minimum interior angle difference. Each characteristic value is calculated. Therefore, sorting is performed in descending order, ascending order, etc. by using any characteristic value as a rearrangement key to rearrange the color arrangement pattern list. This is performed by the color arrangement pattern rearrangement calculation unit 121. For example, the area is a triangular area formed by three colors as shown in FIG.

  By rearranging in this way, it is possible to easily find a sensitivity word close to “tasteful” even if there are many sensitivity words such as 1000 words. FIG. 7 is an example of the result of rearranging the list of color arrangement patterns in descending order of area.

  To explain further, for example, when selecting a color arrangement pattern from the color arrangement pattern list, the color arrangement pattern list is rearranged in ascending order with “delicious” in order to select and compare color arrangements similar to “delicious”. To do.

The “savory” color scheme can be obtained from the color scheme database.
Area 6289.40
Color difference 2.83
Average brightness 5.62
Average saturation 2.79
Information such as can be obtained.

  These numerical values are calculated by converting the color values held in the color arrangement pattern database with any color value such as Munsell value, RGB value, HSV value, L * a * b * value, etc. according to the type of color solid. can do.

  The average brightness is light, the average saturation is flashy, the brightness difference is firm and soft, the area of the triangle created by the three-color scheme corresponds to the activity, etc. There is a clear correlation with the geometric characteristics of the color solid. The color arrangement pattern rearrangement calculation unit analyzes the correlation between the color arrangements, and rearranges the color arrangement patterns using the sensitivity word “delicious”.

  Next, a method for changing a color arrangement pattern using a color solid without using a sensitivity word will be described. That is, the hue, brightness, and saturation values on the screen are adjusted by clicking the button of the color movement section 305.

Assuming that the color pattern is “tasteful” now, the coordinates in the Munsell color solid are as follows.
1. Color coordinates H = 4.7GY of the representative color in the color arrangement area 1
V = 9.1
C = 0.6
2. Color coordinates H = 2.4YR of the representative color of the color arrangement area 2
V = 2
C = 3.1
3. Color coordinates H = 2.5YR of the representative color in the color arrangement area 3
V = 5.5
C = 10.6
It is assumed that the above-mentioned color arrangement is to be changed to the hue, lightness, and saturation values by directly changing the color arrangement movement portion 306 so as to be close to the “delicious” color arrangement pattern.

That is, the coordinates in the Munsell color solid of the “delicious” color scheme 1. Color coordinates H of the representative color in the color arrangement area 1 = 9.6 GY
V = 6.2
C = 7.4
2. Color coordinates H = 4.7GY of the representative color of the color arrangement area 2
V = 9.1
C = 0.6
3. Color coordinate H = 4.6RP of the representative color in the color arrangement region 3
V = 1.6
C = 0.3
