When a shutter release operation is performed at an electronic still camera, an MPU records image data output from an image capturing element into a CF card. The MPU also stores the image data in a transfer buffer memory of an interface circuit. The image data stored in the transfer buffer memory are transferred to a transfer buffer memory provided at an interface circuit of a personal computer connected via an IEEE-1394 cable. The MPU of the personal computer reads out the image data having been taken into the personal computer from the transfer buffer memory and records them in a specific recording area in a recording device.
