Digital camera which detects a connection to an external device
First Claim
1. A method of controlling an electronic camera, comprising the steps of:
- using a switch on the electronic camera for a first function, when the electronic camera is unconnected to a computer;
detecting, by the electronic camera, that the electronic camera is connected to the computer which is a personal computer and the computer is in a state which permits communicating, the personal computer including a display;
using said switch on the electronic camera for a second function which is a function for controlling communicating with the computer, in response to the detecting step detecting that the electronic camera is connected to the computer; and
capturing an image by the electronic camera using a shutter release button of the electronic camera, the shutter release button being different from said switch.

Abstract
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.

5. A method of controlling an electronic camera, comprising the steps of:
-
using a switch on the electronic camera for a first function, when the electronic camera is unconnected to a computer;
detecting, by the electronic camera, that the electronic camera is connected to the computer and the computer is in a state which permits communicating;
using said switch on the electronic camera for a second function in response to the detecting step detecting that the electronic camera is connected to the computer; and
capturing an image by the electronic camera using a shutter release button of the electronic camera, the shutter release button being different from said switch, wherein;
said step of using said switch for the first function uses said switch for the first function which includes displaying images stored in a memory of the camera, and said step of using said switch for the second function uses said switch for the second function which includes transmitting images from a memory of the camera to the computer. - View Dependent Claims (6)
