Abstract: An electronic device according to one embodiment of the present invention can comprise a display panel, a display controller, a memory, and a processor electrically connected to the display panel, the display controller, and the memory. The memory can store instructions, when executed, which allow the process to: draw an image in response to a periodic synchronization signal; compose the drawl image in response to the synchronization signal after the drawing of the image; transmit the composed image to the display controller in response to synchronization signal after the composing of the image; measure, after the transmitting of the composed image, a first standby time until the next synchronization signal is generated; perform control such that the display panel displays an image in response to the generation of the next synchronization signal; determine a first offset value on the basis of the first standby time; and determine an image composition time point by applying the first offset value to the periodic synchronization Additionally, various examples are possible.
