Claims20
A photographing apparatus comprising:
- a) an image capturing unit for generating an image signal from an obtained optical image of an object;
- b) a display unit configured to display at least one of an image or photographing apparatus information;
- c) an operation unit configured to receive manual user input instructions for controlling operations of the photographing apparatus;
- d) a signal transmitter/receiver unit configured to
- (i) transmit a signal to a display device external to the photographing apparatus in order to display the image on the display device, and
- (ii) receive a control signal for the photographing apparatus from the display device;
- and
- e) a power source control unit configured to control power supplied to the display unit and the operation unit, wherein the power source control unit reduces the power supplied to at least one of the display unit or the operation unit responsive to the receipt of a control signal, from the display device, by the signal transmitter/receiver unit.
In a photographing apparatus comprising an image capturing unit for generating an image signal by obtaining an optical image of an object, a display unit for displaying an image and an operation unit for instructing operation, a control method comprising:
- a) transmitting a signal to display the image on a display device external to the photographing apparatus;
- b) receiving a control signal for the photographing apparatus from the display device;
- and
- c) reducing power supplied to at least one of the display unit or the operation unit responsive to the receipt of the control signal.
A method for controlling a digital camera used in a system including an external display device and an external remote control unit, the digital camera including a display unit and an operation unit for receiving manual user input instructions for controlling operations of the digital camera, the method comprising:
- a) providing power to both the display unit and the operation unit;
- b) transmitting image information for display on the external display device;
- c) receiving a control signal from the external display device, the control signal being based on a user operation of the remote-control device causing transmission of a remote control command received by the display device;
- and
- d) reducing the power supplied to at least one of the display unit or the operation unit responsive to the receipt of the control signal.
