Method for controlling camera and electronic device therefor

An electronic device, comprising:

• a first camera;
• a second camera having an angle of view set to be included in an angle of view of the first camera;
• a display;
• and
• a processor configured to:
• set a multi-camera mode, wherein the first camera is activated and the second camera operates in an idle mode, wherein the second camera in the idle mode performs initial setting of the second camera and controls an image sensor of the second camera to maintain a deactivated state,
• obtain a first image via the first camera,
• display, on the display, the first image obtained via the first camera,
• determine whether information is detected in the first image which corresponds to the second camera, and
• when the information detected in the first image is determined to correspond to the second camera:
• activate the second camera, wherein the information is determined to correspond to the second camera based on a determination that an image attribute in the first image obtained via the first camera corresponds to an image area of the second camera,
• display, on the display, at least one object corresponding to activation of the first camera and the second camera, and
• when the information detected in the first image is determined not to correspond to the second camera, maintaining the second camera in the deactivated state while the first camera is activated in the multi-camera mode.
