Abstract: An electronic device is provided. The electronic device includes a display, a processor electrically connected with the display, and a memory electrically connected with the processor. The memory includes instructions, which, when executed by the processor, cause the processor to change a first image such that the first image including a first amount of data is changed to include a second amount of data that is less than the first amount of data, extract at least one dominant color of at least one partial area of the changed first image, perform a gradient in the at least one partial area of the changed first image based on the extracted at least one dominant color, and control the display to display a second image including the at least one partial area to which the gradient is applied on at least one part of the display.
