Abstract
A camera remote control device locally displays information that is derived in the camera. A remote control beam is transmitted from a remote control unit and received by a photo detector on the camera through a light intercepting lens. The received signal is processed in an arithmetic circuit and a CPU and a confirming signal is returned from a light emitting diode in the camera to a receiving circuit in the remote device, as a completion signal. The remote device is responsive to the completion signal to display the state of the camera.
