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.
