The controller 38 interacts with device subsystems such as the display 22, the constant memory 24, random access memory (RAM) 26, a keyboard or keypad 32, speaker 34, an additional input device 28 (e.g., mouse, touch screen, scroll ball, scroll wheel, multi-position navigation key, touch pad, microphone and/or other input devices of user data) and other subsystems of the device.

The operating system 54 and an application program (application) 58 used by the controller 38 are stored in permanent memory 24 (which, for example, may include a hard disk, flash memory or other persistent storage device). In illustrative embodiments, the implementation of the application program 60 color selection is stored in permanent memory 24, by configuring the controller 38 and the device 10 to perform the functions of the display and select a color on sannich below. The color library 62, which contains the information about colors is also stored in permanent memory 24. The application 60 color selection, the color library 62, the operating system 54 and a special application 58 for operation of the device can be fully or partially temporarily loaded into a volatile memory, such as memory 26 and executed by the controller 38.

In illustrative embodiments, implementation, CIELAB color data stored in the color library 62 or retrieved from the database for use in models of psychophysical perception, which are described below. In at least some illustrative embodiments, the implementation of such data CIELAB represent values that correspond to the colours, visible under the light source D65 under the standard angle of view of 10 degrees.

In at least some illustrative embodiments implement the display 22 of the device 10 is calibrated screen, which is pre-configured and tested for color display, within strict limits, to represent the actual colors that are visible in certain lighting conditions. For example, a calibrated display 22 may be provided on the device color selection 10 located at the point of retail sale, for example in the store paints. In some embodiments, the exercise device color selection 0 may be a device without specially calibrated screen, which is owned and operated by interior designer or a regular customer.

Now, after a General overview of the illustrative areas, which can be implemented in the system color picker, will be examined in more detail the operation of the system color selection in the context of the application 60 to select a color and the color library 62 stored in the device color selection 10, as shown in figure 1. In this regard, figure 2 shows an example of a visual graphical user interface 200 to select a color that can be displayed on the display 22 of the device 10. Visual interface 200 has a first and second region 202 and 204 of the display color. The first area 202 of the display color displays a color palette or group of colors selected by the user as a matrix of color elements 211, each of which represents a unique color. In one illustrative embodiment, the color elements 211 are presented as an electronic version of a fan of flowers (fan deck), in which the color elements are arranged vertically on the color depth (increasing from top to bottom with increasing depth of color changes the saturation and reduced brightness) and horizontally shade, although alternative can be used, and other layout color elements 211, and the elements do not have to be displayed in adrichem format for example, the color elements 211 in the display area of the color groups 202 may alternatively be located in the color wheel or can be used another way to represent colors.

Visual interface 200 includes a marker 230 navigate and select that moves across the display 22 in response to user input through the user input device 28 and/or keyboard 62, in order to facilitate the choice of color elements 211 and allow the user to select and use the various functions of the visual interface 200.

In one illustrative embodiment, different color groups can be displayed in the display area of the color group 202, and the interface 200 includes a panel 205 "color groups", which allows the user to choose which color group display. In the illustrative embodiment, the panel color groups allows the user to select a color group for the area 202 of the display depending on: (i) emotional reactions that cause the color ("color emotion") and (ii) levels of color harmony for these colors. With respect to color emotions panel 205 color groups include an option primary select group in the form of the scale 208 "Exciting-Calming", which has four discrete levels, selectable by the user to each of the which is reserved for a specific color group, as will be discussed in more detail below. In relation to color harmony, panel 205 color groups is a secondary option group selection in the form of user-selectable options 210 "All colors" or "Harmony", which, respectively, allow the user or to view all color elements 211 for the selected color group "Exciting-Calming", or to view only a subset of the color elements 211 that fall under a given level of harmony, as will be described in more detail below.

The second area 204 on the visual display 200 serves as a workspace for the evaluation of user-selected pre-flowers. In one illustrative embodiment, the user can choose the desired color from the color elements 211 displayed in the first area 202 of the display using the marker 230 (for example, by double-clicking on the desired color element 211 or by dragging the desired color of the item). After the user selects a color element 211 of the display area of the color groups 202, increased the estimated color element 228 representing the selected color is displayed in the second region 204 of the display. In the shown example, three selected by the user prior color element 228(1), 228(2) and 228(3) shown in the second region 204 of the display, which which may also contain other information about the selected color elements, including, for example, their names 232 and identification codes 234.

The interface 200 also has a third region 206 of the display, which includes a number of linear scales to display information about color harmony pre-selected color elements 228 and emotions caused by the pre-selected color elements. In particular, it is shown the third region 206 of the display contains the scale 212 color harmony and the following color emotions: "Attractive-Unattractive" 214; "Exciting-Calming" 216; "Warm-Cold" 218; "Light-Dark" 220; "Clean-Dirty" 222; "Happy-Sad" 224 and "Funny-Serious" 226. In the shown version of the interface 200 shown only the first word in each of the scales color emotions. In the area of feedback 206 in various embodiments, the implementation can be included smaller scales, additional scale or other scales of color harmony and/or emotions. In some embodiments, the implementation of the colour harmony can be removed, and in some embodiments, the implementation of color emotions can be removed.

As clear from the above description, a visual interface 200 is based on the evaluation of color harmony and color emotion when displaying color groups or to provide feedback on the selected colors. Illustrative is the variants of implementation, evaluation of colour harmony and evaluation of colour emotions used for visual interface 200, determined by quantitative mathematical models derived from psychometric data obtained from the real subjects of the subjects based on their psycho-physical reactions to color. To facilitate further understanding of the proposed system color selection will now be explained the color library 62 and quantitative models used for evaluation of color harmony and evaluation of color emotions.

In one illustrative embodiment, the model used in color selection according to an illustrative options for the implementation of the present invention mimic the human psychophysical perception of colors and combinations of colors and were developed using the data obtained from the subjects of the subjects that showed single colors and combinations of up to three colors and were asked to judge the color by making categorical decisions using bipolar scales the color of emotion and color harmony. For example, to develop a model of colour harmony for combinations of three colors, conducted an experiment on psychophysical perception, is which subjects the subjects were evaluated 6545 tri-color wheels, which contained all possible combinations of the three colors, created from 35 samples of different colors (see table 1, shown in Figure 4), each of which was selected from the CIELAB color space (light source D65 and a standard angle (10 degrees). These 35 different samples of the colors were selected to cover a large color gamut color space CIELAB. Figure 3 shows a diagram of a screen for an experiment in which each subject was shown the color wheel shown separately on a calibrated CRT monitor in a darkened room. Each subject was assessed by the degree of harmony for each of the color wheel, using the scale from 10 categories from "very harmonious" to "extremely disharmonious", after he explained that "harmonious" means "forming a pleasing or consistent whole" and "dis - " means "lack of harmony". The law of categorical judgment of Torgerson [Torgerson, W.S., "Theory and Methods of Scaling, John Wiley & Sons, New York, 1958] was used to convert the experimental data on the scale intervals. Obtained on the scale of values called assessments of color harmony, showing the degree of harmony for each of the color wheel; the higher the score, the more harmonious color wheel seemed subjects. Based on the results of such a test was atrabotana model of colour harmony, described below.

Similar tests were performed to develop models for each of the seven scales of color emotions 212-226 described above. For example, to develop models of color emotions was conducted psychophysical experiment using 35 monochrome plots (using the colors shown in the table 1, figure 4) and 90 tri-color wheel as incentives. Figure 5 and 6 respectively shows a solid plot and tri-color wheel, presents the subject to a subject on a calibrated CRT monitor in a darkened room. Each subject was assessed by the degree of color emotions for each color area and each of the color wheel, using the scale from 10 categories for each of the seven scales of color emotions, after he reported the following dictionary values assigned to each of the scales:

(1) Exciting-Calming

Exciting: causing great enthusiasm and desire

Soothingly: to make (someone) balanced and calm

(2) Attractive-Unattractive

Attractive: offering attractive or enjoyable experience

Unattractive: not having a pleasant or attractive views

(3) Warm-Cool

Warm: related enough or comfortable high temperature

Cold: related to a sufficiently low temperature

(4) Light-Dark

Dark: little or no light

(5) Clean-Dirty

Clean: no dirt, blots or stains

Dirty: coated or filthy unclean substance

(6) Happy-Sad

Happy: feeling or showing pleasure or contentment

Sad: causing a feeling, or leading to a feeling of depression

(7) a Funny-Serious

Funny: funny, entertaining or pleasant

Serious: acting or speaking sincerely and honestly not joking and not hiding

On the basis of the estimates submitted by the participants of the tests, the following models of psychophysical human perception have been developed and used in illustrative embodiments of implementation of the present invention to determine the evaluation of color emotions:

(1) Exciting-Calming

For single color model used to determine an estimation of the psychophysical perception of color emotions on a scale of "Exciting-Calming", the following:

where L*, a* and b* represent the three coordinates of CIELAB for this color. As is well known in this field, these three parameters L*, a* and b* in the CIELAB model represent the three dimensions of color space as follows: L* coordinate of the brightness, showing the color brightness level; a* - coordinate of the red/green when the eat +a* indicates red, and a* indicates the green; and b* coordinate yellow/blue, with +b* indicates yellow, and-b* indicates blue. This model CIELAB further described in the publication "Colorimetric CIE (international Commission on illumination), 3rd edition, publication CIE 15: 2004, ISBN 3901906339.

(2) Attractive-Unattractive

For single color model used to determine an estimation of the psychophysical perception of color emotions on a scale of "Attractive-Unattractive", the following:

where L*, a* and b* represent the three coordinates of CIELAB for this color.

(3) Warm-Cool

For single color model used to determine an estimation of the psychophysical perception of color emotions on a scale of "Warm-Cold", the following:

where C*abhaband L* represents the saturation, hue and brightness of CIELAB for this color.

(4) Light-Dark

where L*, a* and b* represent the three coordinates of CIELAB for this color.

(7) a Funny-Serious

For single color model used to determine an estimation of the psychophysical perception of color emotions on a scale of "Funny-Serious", the following:

where L*, a* and b* represent the three coordinates of CIELAB for this color.

Evaluation of color emotions for colour combinations

For simulation evaluation of color emotions for combinations of two or three colors on six of the seven above-mentioned color scales emotions (excluding scale "Attractive-Unattractive") apply the additivity property that the evaluation of color emotions calculated individually on the above models for each of the colors in the combination, and then average the assessment of colour emotions for all combinations. In particular, for a combination of two colors evaluation of colour emotions can be defined as the way:

where E is the evaluation of colour emotions for a combination of two colors; E1 and E2 represent the evaluation of color emotions of the two constituent colors in this combination.

Similarly, when the combination of the three color evaluation color emotions can be defined as follows:

where E is the evaluation of colour emotions for a combination of three colors and E1-E3 represent the evaluation of color emotions of the constituent colors in this combination.

Thus, evaluation of colour emotions on a scale of "Exciting" for a combination of two or three colors can be determined by averaging the evaluation of color emotions "Exciting-Calming"defined separately for each of the constituent colors in this combination. Evaluation of color emotions for colour combinations for each of the other color scales emotions (excluding scale "Attractive-Unattractive") can be defined in the same way. It is predicted that at least in some embodiments, the evaluation of color emotions for combinations of more than three colors can be assigned to the same methods of averaging, so that the evaluation of colour emotions for any combination of colors can be determined by averaging all estimates emotions of all the colors in this combination.

Evaluation of color e is the otzia for colour combinations using a scale of "Attractive-Unattractive"

Although in some illustrative embodiments, the implementation can use a direct averaging individual estimates colour emotions on a scale of "Attractive-Unattractive" to determine a rough estimate on a scale of "Attractive-Unattractive" for color combinations, the test results show that the correlation between simulated on the model results and the actual results of the tests for colour combinations using averaging is not the same exact scale "Attractive-Unattractive"as for the other six estimates colour emotions. Accordingly, in at least some illustrative embodiments, the implementation uses a different model for the assessment of colour emotions for colour combinations on a scale of "Attractive-Unattractive", and made the difference between adjacent and non-adjacent colors, and in this respect reference is made to Fig.7, which shows combinations of the three colors, including color A, color b and color, where color is related to color and color and color and color And are not adjacent, since they are separated from each other.

United color model "Attractive-Unattractive" consists of two parts, where one (AttractiveArefers to adjacent colors is another AttractiveNto nonadjacent to the colours as shown in Equations (10) and (11) respectively.

For related colors:

where

IC=0.6tanh(1.8-0.05ΔCI)

ILsum=-1.2+0.012Lsumwhere Lsum=L*1+L*2

IΔL=0.15+0.16tanh(-2+0.19ΔL), where ΔL=|L*1-L*2|

IH=ISY1+ISY2

ISY=EC(IS+EY)

EC=0.5+0.5tanh(-2+0.5C*ab)

IS=-0.08-0.14sin(hab+50°)-0.07sin(2hab+90°)

EY=[(0.22L*-12.8)/10]exp{(90°-hab)/10-exp[(90°-hab)/10]}

where L*, C*aband hab- brightness, saturation and hue in the CIELAB system, respectively (with subscript indices 1 and 2 used in the above variables to denote the scores given by the first and second colors, respectively, in the combination of two colors).

For non-contiguous colors:

Model for assessment of color emotions on a scale of "Attractive-Unattractive" for colour combinations with consideration of adjacent and non-adjacent colors is as follows:

Model color harmony

In relation to color harmony, on the basis of the estimates presented subjects subjects were designed following the model used in illustrative embodiments, the implementation of this breath is retene to determine estimates of color harmony for colour combinations. Again, at least in some illustrative embodiments, implementation, made the difference between adjacent colors and non-adjacent colors in the color combinations and model of colour harmony includes two parts, namely CHAto assign the evaluation of color harmony for a pair of adjacent colors in the color combination (see Equation 13, below) and CHNto assign the evaluation of color harmony for a pair of non-adjacent colors in the color combination (see Equation 14 below). After determining the estimated color harmony for all pairs of colors in the color combination of the average assessment, as described below, to determine the evaluation of color harmony for all combinations (see Equation 15 below).

In illustrative embodiments, the implementation of color harmony (CHAfor two adjacent colors is determined by the following equation:

where:

HC=0.04+0.53tanh(0.8-0.045ΔC)

HL=HLsum+HΔL

HLsum=0.3+0.5tanh(-4+0.029Lsum) where Lsum=L*1+L*2

HΔL=0.14+0.15tanh(-2+0.2ΔL) where ΔL=|L*1-L*2|

HH=HSY1+HSY2

HSY=EC(HS+EY)

EC=0.5+0.5tanh(-2+0.5C*ab)

HS=-0.08-0.14sin(hab+50°)-0.07sin(2hab+90°)

EY=[(0.22L*-12.8)/10]exp{(90°-hab)/10-exp[(90°-hab)/10]}

where ΔH*aband ΔC*abrepresent the CIELAB color difference in hue and saturation, respectively; L*, C*aband habrepresent the brightness, saturation and hue of the CIELAB respectively (subscripts 1 and 2 are used in the above variables to denote the scores given by the first and second colors, respectively, in the combination of two colors).

In illustrative embodiments, the implementation of two non-adjacent colors is color harmony CHNdetermined by the following equation:

where:

HC,N=0.2+0.65tanh(1.7-0.045ΔCN)

where ΔH*aband ΔC*abare the color values of the CIELAB difference between non-adjacent colors on the hue and saturation, respectively.

The values of the color harmony for all color combinations can then be determined by averaging the estimates of SN for all color pairs (adjacent or nonadjacent) as follows:

where n is the total number of pairs of colors in the color combination, and CHAand CHNare estimates harmony for adjacent and non-adjacent colors, respectively.

Equation (13) for determining color harmony for two adjacent colors includes the following assumptions:

<> (a) equal hue and equal saturation: any two adjacent colors, changing only in brightness, strive to appear to be harmonious in combination;

(b) high brightness: the higher the brightness value of each color component in a pair of adjacent colors, the greater the probability that this couple will seem harmonious;

(c) unequal brightness: changes the brightness (less than approximately 15 units of color difference in CIELAB) between the component colors in a pair of adjacent colors can reduce the harmony of the pair;

(d) the influence of shade: among the different shades of blue is most likely to create harmony in the combination of two colors, red is the least likely to create harmony. In addition, bright yellow more often create harmony in the combination of two adjacent colors than dark yellow (for example, khaki). On the other hand, of the four principles of color harmony, mentioned in the previous paragraph, only the "(a) the principle of equal hue and equal saturation on the results of research plays a significant role in the harmony of non-adjacent colors that are included in Equation (14).

In alternative embodiments, the evaluation of colour emotion and colour harmony can be modeled using other equations, in addition to the above, which is proposed as one example of the simulation of reaction is the second person on the color. For example, it should be noted that each of the above equations involves constant values in some embodiments, the implementation of the values of these constant values may differ from those listed above. For example, in at least some configurations, for each of the models, except model "Warm-Cold"constants in the above equations can range from 50% to 150% of above values. At least in some configurations for the model "Warm-Cold" constants in the above equations can range from 50% to 110% of above values. In other embodiments, the implementation can be applied to other models of psychophysical perception, instead of or in addition to the models described above. As mentioned above, the model used to implement the proposed methods and devices color selection, simulate psychophysical perception of colour emotions for single colours and colour combinations. Color harmony applies to any combination of colors, while seven color emotions described above can be applied to a single colors and combinations of colors. In this regard, as used herein, the term "psychophysical perception of man" refers to the human response to color or combination of colors at the counter is olonesti more basic sensory perception, such as a basic perception of color. For example, the perception of what color is warm or the color combination is "harmonious", is a reaction or feeling, and hence the psychophysical perception of the person, feeling that the color is "green" or has a specific tint or saturation, is more basic sensory perception. By using mathematical models of psychophysical human perception, which is based on data obtained from a set of subjects of subjects of the herein described embodiments of simulate typical human reactions to colors and color combinations and use this information to assist users in choosing the color. Thus, in illustrative embodiments, the implementation described here are methods and devices for color selection can offer virtual second opinion to your own feelings or color the emotions of the user, which may increase the user's confidence in the choice of color, especially in the situation when the user is confused when considering the numerous colors in a short time. Furthermore, in illustrative embodiments, the implementation described here are methods and devices for color selection can be used to separate some of the total number of possible color options, asking the military to the user, and to reduce confusion when considering the huge number of possible choices.

Now will be described in more detail library colors used in illustrative embodiments of the invention. In one illustrative embodiment, the color library 62 is divided into four different color groups (E1, E2, E3, E4) using the results of Equation (1). Each color group, which is assigned to one of four possible positions on the color scale "Exciting-Calming" 208, presents on the panel 205 color groups on the visual interface 200. In this regard, table 2 Figa is part of the file 62-1 library of colors for color groups (color group E1), which is assigned to the leftmost button on the color scale "Exciting-Calming" 208. As shown in Figa, file 62-1 color library contains for each color: (a) a unique color code (in the column "Code"); (b) the color name; (c) values CEILAB for color, including three coordinates of CIELAB color (L* (brightness), a* and b*)and C*ab (saturation) and hab(shade) CIELAB. Is E color emotions "Exciting-Calming", calculated according to equation (1)provided for each color on Figa, although this information can be taken from the library file colors, as it is may be determined according to the CIELAB values. Returning to Figure 2, in the shown embodiment, the color elements 211, shown in the display area of the color group 202, arranged in rows and columns, at least in one illustrative embodiment, the library file colors 62-1 contains information for each color that defines the location of such color in the matrix of color elements 211 (presented at Figo the leftmost column, entitled "Row-Column"). In the illustrative embodiment, each column represents a color page or a strip of paint, which includes several colors along the color depth, and color that are included in each column were selected manually. When classifying library by color groups calculate the average rating "Exciting-Calming" for each color of the page or column, and color columns then refer to the corresponding color group based on the average evaluation of the "Exciting-Calming".

On FIGU, 8C and 8D shows part of the corresponding files 62-2, 62-3 and 62-3 color libraries, each of which represents a different group of colors that are unique in the range of color emotions "Exciting-Calming". Accordingly, a color group E1 (file 62-1 library) is "very exciting" colors (in one illustrative example the e group E1 consists of 259 colors, with the average 0,78 on a scale of "Exciting-Calming"); color group E2 (file 62-2 library) is "a little exciting colors (in one illustrative example, the group E2 consists of 273 color, with a mean value of 0.15 on a scale of "Exciting-Calming"); color group E3 (file 62-3 library) is "a little soothing colors (in one illustrative example, the group E3 includes 249 colors, with an average value of 0.21 on a scale of "Exciting-Calming"), and color E4 group (file 62-4 library) presents "very soothing colors (in one illustrative example, the E4 group includes 189 colors, with an average value of 0.50 on a scale of "Exciting-Calming"). Although in the illustrative embodiment, each of the four color groups E1, E2, E3 and E4 are defined in separate files the color library 62, in other embodiments, the realization they can be defined in one file and are classified into respective color groups application, select a color 60 on the basis of their estimates of the "Exciting-Calming" (or on the basis of the average marks "Exciting-Calming" for subgroups, such as the color of the column).

Visual interface

A. the display Area color group

Returning to the visual interface 200 of figure 2, in the illustrative embodiment, the implementation of the population, when selected, the leftmost button on the scale of "Exciting-Calming" 206, the color elements 211, the corresponding color group E1 "Very exciting" (file 62-1 library)displayed in the display area of the color group 202. When you select the second button on the scale of "Exciting-Calming" 206, the color elements 211, the corresponding color group E2 "a Little exciting" (file 62-2 library)displayed in the display area of the color group 202, as shown in Fig.9. When you select the third button (i.e. the second from the right) on a scale of "Exciting-Calming" 206, the color elements 211, the corresponding color group E3 "Little soothing" (file 62-3 library)displayed in the display area of the color group 202, as shown in Figure 10. When selected the rightmost button on the scale of "Exciting-Calming" 206, the color elements 211, the corresponding color group E4 "Very soothing" (file 62-4 library)displayed in the display area of the color group 202, as shown in figure 11.

As mentioned above, a color group, shown in the display area of the color group 202 may be further limited by selecting "Harmony" in the elections 210 "All colors" and "Harmony". In the "Harmony of the colors shown in the display area of the color group 202, limited to those colors from a group that by definition otvechayuschiy thresholds harmony. As is clear from equation harmony (13) above, the definition of harmony between a pair of color factor "amount of brightness" (i.e. HLsum) plays an important role in determining the estimated color harmony: the brighter the color is, the more likely that they will create harmony. In the illustrative embodiment, the color elements 211 are arranged vertically on the color depth and horizontal shade. Accordingly, in order to limit the color group to those flowers that have a high probability to harmony, in one illustrative embodiment, the "darker" color removed from the display area of the color group 202 mode harmony. For example, in one embodiment, the selection button "Harmony" option 210 leads to a modification of the interface 200 so that you can see only four of the top row of the selected color group. On Fig shows an example interface 200 in mode "Harmony" with the display of the top four rows of color group E1. Similarly, if each of the color groups E2-E4 is displayed in harmony, only four of the top row are displayed in the area 202 of the display color group.

One possible way to determine the harmony of colors is to use equation harmony (13) to calculate estimates of harmony for each possible combination of color pairs in the group and the village is abusage determine the percentage of those combinations of color pairs in the group, which have a positive evaluation of harmony. For example, the use of this method of calculation harmony in the group assesses color harmony approximately 88% for color group E1, 80% for color group E2, 77% for color group E3, and 61% for the color of E4 group. If each of the four color groups are limited to four upper rows, the computation of the harmony group assesses color harmony approximately 94% for color group E1, 97% for color group E2, 99% for color group E3, and 99% for the color of E4 group. Accordingly, in the illustrative embodiment, the selecting mode harmony of options 210 displays a color group with the assessment of color harmony, at least 94% and above.

Although the interface 200 figure 2 shows only two discrete choice 210 ("All colors" and "Harmony"), these two discrete choice panel 205 can be replaced or discrete scale with more than two options on the scale of harmony, or continuously sliding scale harmony (similar to the scale 212), or numeric drop-down dial that allows the user to choose the desired level of color harmony for color group. Then only the color of the currently selected color group corresponding to the user selected level of color harmony, will appear as the color elements 211 in the field about what the considerations applying a color group. For example, a user may specify that he wants to see only the color of the color group E1 with the assessment of color harmony 90% and above, which will give less color group E1 is displayed in the area 202, compared to the one shown in Figure 2, but larger than shown in Fig. Assessment of harmony for color groups can be used in other ways. For example, while the above quantitative method of determining color harmony group takes into account only the number of positive ratings harmony for each possible combination of color pairs in a color group, you can use a balanced way, taking into account the value of the positive assessments of harmony in addition to the number of positive ratings harmony.

So, it will be clear that the user interface 200 allows the user to filter the color elements 211 displayed in the work area 202 group, based on the desired characteristics of color perception, which is entered by the user (for example, the level of "Exciting-Calming" and/or the level of harmony).

B. work area and region color information

Returning to Figure 2, as mentioned above, users can choose the color elements 211 of the region 202 a color group, and their chosen color elements appear as tentative the basic color elements 228 in the working area 204 of the interface 200. Running application, color selection 60, the controller 38 calculates the evaluation of color harmony and evaluation of color emotions for preliminary color elements 228 in the workspace 204, using equation modeling harmony and emotions (1)to(15)above. The results are presented graphically on the scales "Harmonious-Inharmonious" 212, "Attractive-Unattractive" 214, "Exciting-Calming" 216, "Warm-Cold" 218, "Light-Dark" 220, "Clean-Dirty" 222, "Happy-Sad" 224 and "Funny-Serious" 226 in the field 206 color information. Although the scale shown in figure 2, presents a continuous horizontal stripes, which are filled in to represent the values of the respective evaluation of color harmony and color emotion, information about color harmony and color emotion can be represented in other formats in other variants of implementation. As a non-limiting example, can be the actual numeric values, you can use a discrete scale, and not continuous (for example, discrete scale may look like a scale 208), and/or you can use the vertical scale, and not horizontal.

At each change of a combination of preliminary color elements 228 in the working area 204 (e.g., adding or deleting user prior tsvetova what about the item 228) information displayed on the scales in the field 206 is updated to reflect the current color combination. In one embodiment, when in the working area 204 is only one preliminary color item scale harmony 212 indicates a zero value, but the color emotions show the corresponding estimates colour emotions for single colours.

As mentioned above, for most models of color emotions when dealing with multi-color combinations, no matter whether related preliminary color or not. However, at least in the case of color harmony and color emotion "Attractive-Unattractive, evaluation specific to the preliminary combination of colors depend on the relative orientation of the preliminary color elements. Accordingly, in illustrative embodiments, the implementation of the relative location of the preliminary color elements 228 in the workspace 204 taken into account when calculating ratings on a scale of harmony 212 and colour emotions "Attractive-Unattractive" 214. For example, the interface 200 shown in figure 2, the preliminary color element 228(2), adjacent to both the preliminary color elements 228(1) and 228(3), which are not adjacent to each other, and this relative position is reflected in the scale of harmony 212 and colour emo is AI "Attractive-Unattractive" 214. On Fig shows the interface 200 with exactly the same pre-color elements, as in figure 2 in the working area 204, however, in this case, the provisions of the preliminary color elements 228(2) and 228(3) converted, leading to other estimates on the scale of harmony 212 and colour emotions "Attractive-Unattractive" 214, while the other color emotions 216-226, which do not depend on the relative positioning of the colors remain the same. In illustrative embodiments implement the user can change the pre-color elements 228 in the workspace 228.

In one illustrative embodiment, the device color picker 10 is configured to generate a warning signal when the selected combination of colors in the workspace 204 are below a predetermined threshold color harmony, which may be pre-installed or may be a value that is configurable by the user. For example, the band used to represent the scale of harmony 212 can change color depending on whether the calculated evaluation harmony above or below the threshold, with the green band is used for color combinations above the threshold, and the red bar is used for color combinations below the threshold. On Fig shows the combination for which the warning signal color is howling harmony Generalova in the form of stripes of a darker color, appearing on a scale of harmony 212, but not on other scales (or on the scale of harmony 212, shown in figure 2 for the same colors in a different order). The warning signal of harmony may have various shapes, including, for example, other visual and/or acoustic stimuli generated by the device color selection 10. In addition, the device color selection 10 may also be configured to issue a warning signal thresholds for all or selected color scales emotions, shown in region 206, if the appropriate evaluation of color emotions will fall below threshold levels. In at least some illustrative embodiments, the implementation timeline, which provides warning signals and thresholds define a warning signal can be configured by the user using the default values set by the designer involved in configuring application of color selection 60.

As shown in Fig, in one illustrative embodiment, the interface 200 includes the option button "Print" 231 through which the user can print the pre-color elements 228, color names 32 and identification number of colors 32 contained in the working area 204.

In some embodiments, the implementation of the application program color selection 60 allows users to import is on a new color library 62 sorts and colors for the respective color groups (for example, color groups E1, E2, E3 and E4), for example, on the basis of the provisions of the colors on the scale of "Exciting-Calming", and the hue and brightness of colors, as shown in Fig.

In at least some illustrative embodiments, the implementation of the data by color contained in the color library 62 may have a form different from the form data CEILAB, including, for example, XYZ data (under illuminant D65, A, F2, TL 84 and others) or the reflectivity data (R%). In such cases, or other format data by color can be converted into a format CEILAB and then used in the above equations, or equations can be modified for a different format. For example, in one embodiment, a dynamic-link library (DLL) is used to calculate values for color emotions (CE) or color harmony (CH), as shown in Fig.

In some illustrative embodiments, implementation of discrete scales are used to represent values of color harmony and color emotion, for example, by using numbers from 1 to 10 to represent discrete degrees on each scale; 10 means the highest degree of the first element in each word pair, meaning "Bright", "Warm", "Exciting", "Funny", "Happy", "Net", "Attractive" and "Harmonious"; 1 means the highest degree of the second e is ment, i.e. "Dark", "Cold", "Soothing", "Serious", "Sad", "Dirty", "Unattractive" and "Disharmonious". In table 6, below, presents values that define the range of values of CE and SN, the corresponding discrete degrees, shown in the left column.

In illustrative embodiments, the implementation described here, embodiments of the system color picker you can use to help people when choosing paint, but it can also be applied in other areas where is is the coordination of colors, for example, when selecting fabrics for upholstery, matching the color of the Wallpaper, the selection of colors in fabrics, colour selection of household appliances, etc.

In some illustrative embodiments, the implementation of some or all assessments of colour emotion and colour harmony of colors and color combinations can be pre-defined and can be stored in lookup tables, which are an integral part of the color library 62.

SUBSTANCE: each value of the discrimination threshold corresponding to each obtained luminance value, which is intended to be assigned for each panel gradation unit, is received by the gradation correcting method. The pixel value corresponding to each discrimination threshold value is obtained for each panel gradation unit. The threshold epsilon-filter value is obtained by the inverse gamma-correction of the relationship between the distinct values of the discrimination threshold corresponding to the panel gradation units and the maximum panel output value. Based on the linear approximation function, they are obtained by the method of the least squares. The threshold epsilon-filter value is defined as the increasing function of the pixel value on the basis of the permitted number of steps of the discrimination threshold values and is changed according to the central pixel value.

EFFECT: reduction of the image distortion caused by the halo effect.
