发明名称 Digital camera which detects a connection to an external device
摘要 An electronic camera and method of operating an electronic camera which detects whether an external device such as a personal computer is properly connected to the camera and in a state which permits communication. The camera monitors a data terminal ready (DTR) signal of an RS-232 connection in order to determine that the external device is properly connected and in a state which permits communication. Once the proper connection is detected, the camera can either transmit or receive images and/or audio from the external device. Accordingly, a specific switch which places the camera in a communication mode can be eliminated. Further, a single switch may be utilized for both controlling whether the camera records or plays images when there is no device connected, and which controls whether the camera transmits or receives images and/or audio when an external device is determined to be connected.
