Abstract: An electronic device includes a display, and at least one processor. The at least one processor is configured to obtain an image; identify whether or not the luminance of the display equals to or is higher than a predetermined luminance; when the luminance of the display equals to or is higher than the predetermined luminance, identify the FPS of the image and the motion information of a scene of the image to be displayed by means of the display, and determine a refresh rate of the display based on the FPS of the image and the motion information of the scene; and, when the luminance of the display is lower than the predetermined luminance, determine a refresh rate corresponding to the FPS of the image as the refresh rate of the display, and display the scene of the image by means of the display based on the determined refresh rate.

Abstract: An electronic device is provided. The electronic device includes communication circuitry configured to communicate with an external electronic device, a processor operatively connected with the communication circuitry, and a memory operatively connected with the processor. The memory may store instructions which, when executed, cause the processor to control the electronic device to: obtain environment information associated with a video playback environment of the external electronic device, decode a high dynamic range (HDR) video, perform color conversion of the decoded HDR video based on the environment information, encode the color-converted video into a standard dynamic range (SDR) format, and transmit the encoded video to the external electronic device via the communication circuitry.

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.
