Certain embodiments of the disclosure relate to electronic devices and methods for controlling the display of images each obtained by a respective one of cameras. To that end, an electronic device comprises a first camera having a first view angle, a second camera having a second view angle smaller than the first view angle, a display, and a processor configured to obtain a first image corresponding to an external object using the first camera and a second image corresponding to the external object using the second camera, control the display to display the first image, in response to a request to adjust a magnification of the displayed first image, when the magnification meets a designated first condition, control the display to display a first synthesized image obtained by synthesizing at least a portion of the first image with the second image resized to correspond to at least the portion of the first image, and when the magnification meets a designated second condition, control the display to display a second synthesized image obtained by synthesizing at least a portion of the second image with at least the portion of the first image. Other certain embodiments are also possible.
