Abstract: A method for providing a preview and an electronic device for displaying a preview are provided. The electronic device includes a camera module, a display, a processor operatively connected to the camera module and the display, and a memory operatively connected to the processor, wherein the memory stores instructions which, when executed, cause the processor to acquire original image frames through the camera module, display, on the display, first preview image frames corresponding to the acquired original image frames, receive an input for requesting dynamic-tone-mapping-based recording, perform the dynamic-tone-mapping-based recording in response to the reception of the input, and while performing the dynamic-tone-mapping-based recording, generate second preview image frames by performing dynamic-tone-mapping processing to first preview image frames acquired after a time point at which the input is received, and display the generated second preview image frames on the display. Various other embodiments are possible.

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.
