A multi-imaging apparatus includes: a display unit; an internal imaging device that acquires a first live view image or a first image captured by a main imaging operation thereof; a wireless communication unit that performs wireless communication with an external imaging device that acquires a second live view image or a second image captured by a main imaging operation thereof; and a controller. Here, the controller receives an input of the first live view image from the internal imaging device, receives the second live view image from the external imaging device through the wireless communication unit, and causes the display unit to display the input first live view image and the received second live view image as a multi-live view.
