(23) Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

(24) In an apparatus and method for changing a color of weather presenter's costume in real time based on weather information according to an embodiment of the present invention, overall weather information is transmitted emotionally and intuitively through the color of weather presenter's costume by using the fact that general persons recognize the same color as different colors depending on the degrees of darkness and lightness.

(25) Specifically, in an apparatus and method for changing a color of weather presenter's costume in real time based on weather information according to an embodiment of the present invention, based on an HSV color model, by representing temperature through the hue of weather presenter's costume, representing fine dust level through the saturation of weather presenter's costume, and representing relative humidity through the value of weather presenter's costume, given overall weather information is emotionally and intuitively provided to a viewer.

(26) Referring to FIG. 1, an apparatus for changing a color of weather presenter's costume in real time based on weather information according to an embodiment of the present invention includes a control unit 103 configured to determine a color representing given weather information from a weather forecast database (DB) 115, a color change unit 110 configured to change a color of weather presenter's costume into the determined color, and a memory 109 configured to store a color fuzzy model 104, 106, and 108 for representing weather information in color.

(27) In an embodiment of the present invention, the weather information may include temperature, fine dust level, and relative humidity.

(28) Also, the color fuzzy model is based on an HSV color model in which a color is determined by hue, saturation, and value, the color fuzzy model is to represent temperature, fine dust level, and relative humidity in corresponding hue, saturation, and value respectively, the control unit 103 determines hue, saturation, and value corresponding respectively to given temperature, fine dust level, and relative humidity based on the color fuzzy model, and the color change unit 110 changes a color of weather presenter's costume into a color based on the determined hue, saturation, and value.

(29) The memory 109 includes an input membership function 104 including a temperature membership function 116, a fine dust level membership function 118, and a relative humidity membership function 120 for respectively changing temperature, fine dust level, and relative humidity into linguistic variables perceived by humans, an output membership function 106 including a hue membership function 122, a saturation membership function 124, and a value membership function 126 for respectively representing the temperature, fine dust level, and relative humidity in hue, saturation, and value, and a predetermined fuzzy rule 108 for matching the input membership function 104 to the output membership function 106.

(30) The control unit 103 includes a fuzzy inference unit 100 configured to infer a hue fuzzy set, a saturation fuzzy set, and a value fuzzy set corresponding respectively to given temperature, given fine dust level, and given relative humidity by matching the input membership function 104 to the output membership function 106 based on the predetermined fuzzy rule 108 with respect to each of the given temperature, the given fine dust level, and the given relative humidity, and a defuzzification unit 102 configured to determine a hue coordinate corresponding to the given temperature, a saturation coordinate corresponding to the given fine dust level, and a value coordinate corresponding to the given relative humidity by respectively defuzzifying the inferred hue fuzzy set, saturation fuzzy set, and value fuzzy set.

(31) Operations of the above apparatus for changing a color of weather presenter's costume in real time based on weather information according to an embodiment of the present invention will be described below.

(32) Referring to FIG. 1, the fuzzy inference unit 100 receives numerical data of temperature, fine dust level, and relative humidity from weather forecast database 115 and respectively changes given temperature, given fine dust level, and given relative humidity into linguistic variables perceived by humans, based on the temperature membership function 116, the fine dust level membership function 118, and the relative humidity membership function 120.

(33) FIG. 3 is a diagram illustrating a membership function about temperature, and FIG. 4 is a table illustrating linguistic terms (linguistic variables) about temperature.

(34) Referring to FIGS. 3 and 4, it may be seen that when the temperature is a numerical value of 18 C., the temperature is NORMAL (a degree of membership of 0.5) and WARM (a degree of membership of 0.5).

(35) FIG. 5 is a diagram illustrating a membership function about fine dust level, and FIG. 6 is a table illustrating linguistic terms (linguistic variables) about fine dust level.

(36) Referring to FIGS. 5 and 6, it may be seen that when the fine dust level is a numerical value of 120 g/m.sup.3, the fine dust level is SLIGHTLY BAD (a degree of membership of 0.5) and BAD (a degree of membership of 0.5).

(37) FIG. 7 is a diagram illustrating a membership function about relative humidity, and FIG. 8 is a table illustrating linguistic terms (linguistic variables) about relative humidity.

(38) Referring to FIGS. 7 and 8, it may be seen that when the relative humidity is a numerical value of 85%, the relative humidity is HUMID (a degree of membership of 0.5) and VERY HUMID (a degree of membership of 0.5).

(39) Then, based on the predetermined fuzzy rule 108, the fuzzy inference unit 100 infers the hue fuzzy set corresponding to the temperature by matching the temperature membership function 116 and the hue membership function 122, infers the saturation fuzzy set corresponding to the fine dust level by matching the fine dust level membership function 118 and the saturation membership function 124, and infers the value fuzzy set corresponding to the relative humidity by matching the relative humidity membership function 120 and the value membership function 126.

(40) Meanwhile, referring to FIG. 9, in a cylindrical HSV color model, the color is determined by the hue defined as an angle of 0 to 360 (or 0 rad to 2 rad) and the value and the saturation defined as 0% to 100% (or a real number of 0 to 1) to complement the hue.

(41) FIG. 10 is a diagram illustrating a membership function about hue, and FIG. 11 is a table illustrating linguistic terms (linguistic variables) about hue.

(42) FIG. 12 is a diagram illustrating a membership function about saturation, and FIG. 13 is a table illustrating linguistic terms (linguistic variables) about saturation. The hue of color may be associated with the saturation of air. For this reason, it is useful to represent fine dust information in color saturation. For example, the fine dust level may be intuitively represented by reducing the saturation of color (that is, by making the color darker) as the fine dust level increases. In the HSV color model, the saturation is continuously distributed between 0 to 1 as represented by the membership function about saturation illustrated in FIG. 12.

(43) FIG. 14 is a diagram illustrating a membership function about value, and FIG. 15 is a table illustrating linguistic terms (linguistic variables) about value. The value may be associated with cloudy weather or sunny weather. Since the relative humidity is 100% in a rainy day, it may be represented in black color. For example, the fine dust level may be intuitively represented by reducing the value of color (that is, by making the color darker as gray series) as the relative humidity increases. In the HSV color model, the value is continuously distributed between 0 to 1 as represented by the membership function about value illustrated in FIG. 14.

(52) Rule 8: If [temperature] is [COLD] then [the Hue] is [CYAN.BLUE].

(53) Rule 9: If [temperature] is [VERY COLD] then [the Hue] is [BLUE].

(54) Rule 10: If [temperature] is [EXTREMELY COLD] then [the Hue] is [BLUE.MAGENTA].

(55) Rule 11: If [the fine dust level] is [GOOD] then [the saturation] is [VERY HIGH].

(56) Rule 12: If [the fine dust level] is [NORMAL] then [the saturation] is [HIGH]

(57) Rule 13: If [the fine dust level] is [SLIGHTLY BAD] then [the saturation] is [NORMAL]

(58) Rule 14: If [the fine dust level] is [BAD] then [the saturation] is [LOW].

(63) Rule 19: If [the Relative Humidity] is [HUMID] then [the Value] is [LOW].

(64) Rule 20: If [the Relative Humidity] is [VERY HUMID] then [the Value] is [VERY LOW].

(65) Rule 21: If [the Relative Humidity] is [WET(Rain)] then [the Value] is [DARK].

(66) The defuzzification unit 102 determines a hue coordinate (HC) corresponding to the given temperature, a saturation coordinate (SC) corresponding to the given fine dust level, and a value coordinate (VC) corresponding to the given relative humidity in the HSV color model by respectively defuzzifying the inferred hue fuzzy set, saturation fuzzy set, and value fuzzy set, for example, by using a defuzzification method using a center-of-gravity method.

(67) The color change unit 110 changes a color of weather presenter's costume in a weather forecast broadcast signal into a color on the HSV color model based on the determined hue coordinate (HC), saturation coordinate (SC), and value coordinate (VC).
