Method and apparatus for changing background color of toolbar with dominant color of picture

An apparatus for changing a background color of a toolbar with a dominant color of a picture, comprising:

• a computing device;
• memory storing instructions, when executed by the computing device, configured to cause the computing device to:
• transparentize a background color of a toolbar of a currently running application;
• extract a dominant color of a picture currently displayed on a user interface of the application;
• display, along with the picture, the toolbar using a color based on the extracted dominant color as the background color of the toolbar on the user interface of the application, such that the toolbar and the picture are displayed harmoniously;
• and
• when the displayed picture is moved up and down or left and right with a user operation, keep the background color of the toolbar unchanged from the color based on the extracted dominant color when the displayed picture is not completely moved out of an operation interface;
• and recover the background color of the toolbar to a default color when the displayed picture is completely moved out of the operation interface and the operation interface does not have a picture or a color to display.

A computer-based method for changing a background color of an element bar in accordance with a dominant color of a picture, comprising:

• transparentizing, based on an instruction included in program code executed by a computing device, a background color of an element bar of a currently running application;
• extracting, based on an instruction included in program code executed by the computing device, a dominant color of a picture currently displayed on a user interface of the application;
• displaying, based on an instruction included in program code executed by the computing device, the element bar using a color based on the extracted dominant color as the background color of the element bar, along with the picture on the user interface of the application, such that the element bar and the picture are displayed harmoniously;
• and
• when the displayed picture is moved up and down or left and right with a user operation, keeping the background color of the toolbar unchanged from the color based on the extracted dominant color when the displayed picture is not completely moved out of an operation interface;
• and recovering the background color of the toolbar to a default color when the displayed picture is completely moved out of the operation interface and the operation interface does not have a picture or a color to display.
