As a result, the terminal device 110 according to an embodiment of the present invention grasps the display method of the terminal device 110 and displays the color on the screen currently being output through the display of the terminal device 110 according to the display method. By changing the power to a predetermined color to reduce the power consumption, it is possible to reduce the power consumption of the terminal device 110 generated when the screen is output through the display.

According to an embodiment of the present invention, the color database 112, which stores power consumption information for when a plurality of colors are output for each of a plurality of display scheme information, indicates a similarity of colors between the plurality of colors. Color similarity information may be additionally stored.

In this regard, the color similarity information may be additionally stored in the color database 112 as shown in the example of Table 3 below.

Red green blue ... Red 100 20 25 ... green 20 100 70 ... blue 25 70 100 ... ... ... ... ... ...

Here, the numbers described in each cell in Table 3 refers to an index indicating the degree of color similarity.

In this case, the color converter 115 refers to the extracted at least one representative color with reference to the color database 112 based on the display method information of the terminal device 110 extracted through the display extractor 113. It is possible to convert a color having a predetermined power consumption reduction ratio and at the same time having a predetermined color similarity.

For example, as shown in Table 1 above, information is stored in the display database 111, and display model information for the terminal device 110 is identified as "bcde1" so that the display extracting unit 113 displays the display database 111. Assume that the display method information of the LCD system corresponding to "bcde1" is extracted from.

In addition, as shown in Tables 2 and 3, information is stored in the color database 112, and the screens outputted through the display of the terminal device 110 by the representative color extracting unit 114 are 25 areas. As a result of extracting the representative colors for each area divided by 25, the color converting unit 115 stores a plurality of colors stored for the LCD system of the color database 112 as shown in Table 2 above. The 25 representative colors have a predetermined power consumption reduction ratio and a selected color similarity with reference to power consumption information about colors and color similarity information stored in the color database 112 as shown in Table 3 above. You can convert to color.

If the representative color of any one of the 25 representative colors is green, the color similarity selected in association with the color conversion for the green is 70%, and the selected power consumption reduction ratio is set to about 7%. In this case, the color converter 115 may convert the green color to blue color with reference to the color database 112.

Here, the selected power consumption reduction ratio and the selected color similarity information may be set by the user, and the user may adjust the power consumption reduction ratio and the color similarity in real time with respect to conversion of the representative color.

In this regard, the terminal device 110 may further include a user interface (UI) output unit 120.

The UI output unit 120 may output the configured UI by configuring a predetermined type of UI guiding adjustment of a power consumption reduction ratio and color similarity associated with color conversion of the extracted at least one representative color.

In this regard, FIG. 2 illustrates an example of a UI that may be output through the UI output unit 120.

As illustrated in FIG. 2, the UI output unit 120 may output a predetermined scroll bar 210, and the user may adjust the power consumption reduction rate and color similarity in real time using the indicator 220. .

If the user moves the indicator 220 at the position of the first step 231 of the left part of the scroll bar 210, the color converter 115 is currently output through the display of the terminal device 110. Colors can be converted while changing the target value of the power consumption reduction rate as long as the color present does not fall within a range of specific color similarities.

For example, when the user moves the indicator 220 from the left to the right within the position of the first step 231 of the scroll bar 210, the color converter 115 displays the color in real time to increase the power consumption reduction rate. While converting, the color can be changed within a range of predetermined color similarities.

In addition, when the user moves the indicator 220 at the position of the second step 232 of the middle portion of the scroll bar 210, the color converter 115 is currently output through the display on the terminal device 110 and Without changing the range of color similarity for a given color, the color can be converted while changing the target value of the power consumption reduction ratio.

For example, when the user moves the indicator 220 from left to right within the position of the second step 232 of the scroll bar 210, the color converter 115 may reduce the power consumption rate without limiting the color similarity. Color can be converted in real time.

Finally, when the user moves the indicator 220 at the position of step 3 233 of the right portion of the scroll bar 210, the terminal device 110 lowers the brightness itself of the display relative to the terminal device 110. As a result, the power consumption can be reduced.

According to an embodiment of the present invention, the terminal device 110 may further include a conversion information storage unit 119.

When the color conversion for the at least one representative color is completed in the color conversion unit 115, the conversion information storage unit 119 displays the display method information extracted by the display extraction unit 113 and the color for the at least one representative color. The conversion completion information is stored in correspondence with each other.

As a result, when the color conversion for the representative color is completed through the color conversion unit 115, the conversion information storage unit 119 stores color conversion completion information, so that the terminal device 110 may reduce power consumption later. Without performing the process again, the color conversion can be performed immediately, thereby improving performance of the terminal device 110 related to color conversion for reducing power consumption.
