Method for controlling refresh rate, and electronic device supporting same

An electronic device comprising:

• a display;
• and
• at least one processor including processing circuitry;
• and
• memory storing instructions that, when executed by the at least one processor individually or collectively, cause the electronic device to:
• obtain an image,
• identify whether a luminance of the display is equal to or greater than a specified luminance, the luminance of the display being an amount of a light, emitted or reflected from a surface of the display, per unit area in a given direction,
• based on the luminance of the display being equal to or greater than the specified luminance:
• identify FPS (frames per second) of the image and motion information of a scene of the image to be displayed through the display, the FPS of the image being a number of frames, included in the image, displayed in one second, and
• based on the FPS of the image and the motion information of the scene, determine a refresh rate of the display, the refresh rate of the display being a number of times at least a portion of the image is displayed per second,
• based on the luminance of the display being less than the specified luminance, determine a refresh rate corresponding to the FPS of the image as the refresh rate of the display, and
• based on the determined refresh rate, display the scene of the image through the display.
