Abstract

A camera system including a camera which performs data communication with external equipment. The external equipment is connected to a communication terminal in the camera via a connector, such as a cable. The camera and the external equipment initially perform communication at a predetermined initial communication speed via the communication terminal and cable. The camera system includes a device to transmit a communication speed change command to the camera at the initial value of communication speed, and a device to change the initial value of communication speed to a high speed based upon the received communication speed change command. The camera system further includes a device to restore the communication speed to the original initial value of communication speed by generating a communication end command which is transmitted to the camera during communication with the external equipment.
