Abstract

An electronic device according to the present disclosure includes a display and at least one processor. The display shows a background image and a display object arranged on the background image, the background image including a plurality of colors. The at least one processor controls the display. When a first color that occupies the largest area in a first region including at least part of the background image and a second color that occupies the largest area in the display object included in the first region are similar, the at least one processor uses a third color different from the first color and the second color to enhance the display object.

First claim

1 . An electronic device comprising:
a display configured to show a background image and a display object arranged on the background image, the background image including a plurality of colors; and at least one processor configured for controlling the display to
identify a first color that occupies the largest area in a first region including at least part of the background image,
identify a second color that occupies the largest area in the display object included in the first region,
determine whether or not the first color and the second color are similar, and
when the first color and the second color are similar, use a third color different from the first color and the second color to enhance the display object.

2 . The electronic device according to claim 1 , wherein
the at least one processor is configured to
identify the first color by calculating a first RGB value of the first color, identify the second color by calculating a second RGB value of the second color, and
determine that the first color and the second color are similar when a distance in an RGB color space between a first point corresponding to the first RGB value and a second point corresponding to the second RGB value is smaller than a predetermined threshold value, and
a distance in the RGB color space between the first point and a third point corresponding to an RGB value of the third color is larger than the predetermined threshold value.

3 . The electronic device according to claim 1 , wherein the third color includes a complementary color of the first color.

4 . The electronic device according to claim 1 , wherein when the first color and the second color are similar, the at least one processor is configured to change the second color to the third color to enhance the display object.

5 . The electronic device according to claim 1 , wherein when the first color and the second color are similar, the at least one processor is configured to change a color that occupies the largest area, among colors used for the background image, to the third color in a second region to enhance the display object, the second region having a smaller area than the first region and including the display object included in the first region.

6 . The electronic device according to claim 5 , wherein when the first color and the second color are similar, the at least one processor is configured to change all colors used for the background image to the third color in the second region to enhance the display object.

7 . The electronic device according to claim 1 , wherein
the at least one processor is configured to divide the background image into a plurality of regions, and the first region is one of the plurality of regions.

8 . The electronic device according to claim 1 , wherein the first region includes the background image entirely.

9 . The electronic device according to claim 1 , wherein the electronic device includes a mobile terminal.

10 . An image processing method for controlling a display of an electronic device by at least one processor included in the electronic device, the display being configured to show a background image and a display object arranged on the background image, the background image including a plurality of colors, the at least one processor being configured to control the display, the image processing method comprising:
identifying a first color that occupies the largest area in a region including at least part of the background image; identifying a second color that occupies the largest area in the display object included in the region; determining whether or not the first color and the second color are similar; and when the first color and the second color are similar, using a third color different from the first color and the second color to enhance the display object.
