Abstract: A method and electronic device are provided for providing a high dynamic range (HDR) image. The HDR image is obtained. A first area, in which the HDR image is displayed, and a second area, in which an image is displayed, are identified within a screen. The first area is white point-processed based on a first white point, and the second are is white point-processed based on a second white point that is set for a display of the electronic device and different from the first white point. The screen including the white point-processed first area and the white point-processed second area is displayed on the display.
