摘要:
A photographing apparatus wirelessly transmitting an image and a method of controlling the photographing apparatus are provided, in which, a wireless transmitter wirelessly transmits an image to an external apparatus, and a controller controls the wireless transmitter to transmit to the external apparatus at least one of an image generated through photographing and an image pre-stored in a storage unit. Thus, an image, which is being photographed, can be stored and modulated, and transmitted to prevent the photographed image from disappearing. Also, the image can be stored, and another image can be displayed on an external apparatus to provide convenience to a user.
