1. An electronic device comprising:
a camera module comprising a first camera having a first field of view (FOV) and a second camera having a second FOV narrower than the first FOV, the second FOV is positioned in the first FOV;
a motion sensor; and
a processor electrically connected to the camera module and the motion sensor,
wherein the second camera comprises:
at least one lens;
a reflective member configured to rotate relative to the at least one lens; and
an image sensor configured to generate an electrical signal based on light incident through the reflective member and the at least one lens, and
wherein the processor is configured to:
obtain an image using the camera module;
obtain, from the motion sensor, first movement information of the electronic device which is shaken, to correspond to the obtaining of the image;
obtain information on movement of the reflective member of the second camera according to at least one of an optical image stabilizer (OIS) correction operation or an object tracking operation during at least a portion of a period in which the image is obtained;
obtain output information by performing an image stabilization operation with respect to the image, based on at least one of the first movement information or the information on the movement of the reflective member; and
output an image corrected by correcting distortion of the image, based on a distortion variation resulting from the movement of the reflective member and the output information.
