KR-20260067723-A - ELECTRONIC APPARATUS AND METHOD FOR CONTROLLING THEREOF

Abstract

The electronic device includes an input/output interface, a memory for storing at least one instruction, and at least one processor for executing at least one instruction. When the at least one processor acquires a first image having a variable refresh rate through the input/output interface and acquires a second image having a fixed refresh rate, it generates a multi-view screen in which the first image and the second image are displayed together by varying the screen refresh rate of the second image based on the current refresh rate corresponding to the variable refresh rate.
