Abstract
A system includes a computer and digital camera connected to each other; automatic image transfer or remote control can be achieved readily, and a power supply route is simple. A card connector for an I/O card and a back connector thereof are linked by a power supply line. When the I/O card is connected to a digital camera, power supplied over an interface cable joined with the back connector is supplied to the digital camera. Moreover, when the I/O card is connected to the digital camera, a start-up instruction signal is sent from the I/O card to the digital camera. A CPU in the digital camera executes start-up processing.
