Abstract

An electronic device and a method of extracting a color in the electronic device are provided. The electronic device includes a display unit configured to display an image and a controller configured to extract at least one color value from the image, and to extract a color value satisfying a range of color deviation from the extracted color values.

First claim

What is claimed is:

1. A method of extracting a color in an electronic device, the method comprising:
extracting a plurality of colors, each of which is represented by an RGB triplet having an R value, a G value, and a B value, from an icon image;
selecting a predetermined number of colors from the extracted a plurality of colors based on a portion occupied by each of the plurality of colors within the icon image;
determining at least one color, among the predetermined number of colors, having an R value, a G value, and a B value satisfying a range of color deviation, wherein the color deviation comprises a difference between a maximum of the R, G and B values and a minimum of the R, G and B values determined in advance;
extracting a color from the at least one color based on a priority;
determining the extracted color as a representative color of the icon image; and
displaying the representative color as a background color of a screen of an application related to the icon image.

2. The method of claim 1 , wherein the plurality of colors comprises dominant colors of the icon image, and object colors from the icon image.

3. The method of claim 2 , further comprising: selecting the predetermined number of colors from the extracted dominant colors and the extracted object colors.

4. The method of claim 3 , wherein the predetermined number of colors are selected in a descending order of area from the dominant colors and the object colors.

5. The method of claim 1 , wherein the color deviation is a numerical value corresponding to the difference.

6. The method of claim 1 , further comprising:
extracting an average color using the plurality of colors.

7. The method of claim 1 , further comprising extracting a color having a highest priority from the at least one color based on a size of a portion occupied by the at least one color within the icon image.

8. An electronic device comprising:
a display unit configured to display an icon image; and
at least one processor configured to:
extract a plurality of colors, each of which is represented by an RGB triplet having an R value, a G value, and a B value, from the icon image,
select a predetermined number of colors from the extracted plurality of colors based on a portion occupied by each of the plurality of colors within the icon image,
determine at least one color, from among the predetermined number of colors, having an R value, a G value, and a B value satisfying a range of color deviation, wherein the color deviation comprises a difference between a maximum of the R, G and B values and a minimum of the R, G and B values determined in advance,
extract a color from the at least one color based on a priority,
determine the extracted color as a representative color of the icon image, and
display the representative color as a background color of a screen of an application related to the icon image.

9. The electronic device of claim 8 , wherein the plurality of colors comprises dominant colors of the icon image and object colors in the icon image.

10. The electronic device of claim 9 , wherein the at least one processor is further configured to select the predetermined number of colors from the extracted dominant colors and the extracted object colors.

11. The electronic device of claim 10 , wherein the at least one processor is further configured to select the color in a descending order of area from the extracted dominant color and the extracted object color.

12. The electronic device of claim 8 , wherein the color deviation comprises a numerical value corresponding to the difference.

13. The electronic device of claim 8 , wherein the at least one processor is further configured to extract an average color using the plurality of colors.

14. The electronic device of claim 8 , wherein the at least one processor is further configured to extract a color having a highest priority from the at least one color based on a size of a portion occupied by the at least one color within the icon image.

15. A non-transitory computer-readable storage medium with an executable computer program stored thereon, wherein the computer program instructs at least one processor to perform operations for:
extracting a plurality of colors, each of which is represented by an RGB triplet having an R value, a G value, and a B value, from an icon image;
selecting a predetermined number of colors from the extracted a plurality of colors based on a portion occupied by each of the plurality of colors within the icon image;
determining at least one color, among the predetermined number of colors, having an R value, a G value, and a B value satisfying a range of color deviation, wherein the color deviation comprises a difference between a maximum of the R, G and B values and a minimum of the R, G and B values determined in advance;
extracting a color from the at least one color based on a priority;
determining the extracted color as a representative color of the icon image; and
displaying the representative color as a background color of a screen of an application related to the icon image.
