1. An electronic device comprising:
a first camera;
a first communication circuitry configured to establish a cellular communication connection;
a second communication circuitry configured to establish a short-range communication connection;
at least one processor; and
memory for storing instructions that, when executed by the at least one processor, cause the electronic device to:
establish the short-range communication connection with an external device comprising a second camera using the second communication circuitry,
establish the cellular communication connection with a counterpart device using the first communication circuitry,
determine an image format can be supported by the electronic device, the external device and the counterpart device,
when performing a video call with the counterpart device using the second camera, receive, via the second communication circuitry from the external device, second image data in the determined image format, which is acquired from the second camera of the external device, and transmit, via the first communication circuitry to the counterpart device, the second image data, and
when an event related to camera switching is detected while transmitting the second image data to the counterpart device, transmit, via the first communication circuitry to the counterpart device, first image data in the determined image format, which is acquired from the first camera.
