Apparatus for and a method of communicating between a camera and external equipment
First Claim
1. A camera system, comprising:
- a camera including a communication terminal;
an external device connected to the communication terminal of the camera, the camera and the external device performing communication at an initial communication speed via the communication terminal;
a communication speed change command device to transmit a command to the camera to change the initial communication speed; and
a communication speed change device to change the communication speed based on the communication speed change command,wherein after the communication speed is changed, communication between the camera and the external equipment is performed at the changed communication speed.

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.

12. A system for performing communication between a camera and an external device, comprising:
-
an equipment type command generator to send an equipment type command to the camera at an initial predetermined baud rate to determine whether the camera is a type which is compatible with the external device; an equipment type generator to receive the equipment type command from the equipment type command generator, and to confirm that the camera is a type which is compatible with the external device; and a speed change device to send a baud rate change command to the camera to change the initial communication speed when the equipment type generator confirms that the camera is a type compatible with the external device.
