ABSTRACT:
An apparatus for wireless-controlling a camera and for two-direction simultaneous control of an electrically-driven pan head on which the camera is mounted, including a camera-side transmitter-receiver for modulating and transmitting an image signal from the camera and pulse data on the state of the camera, receiving and demodulating the signal transmitted from an operating-side transmitter-receiver, and supplying the demodulated signal to the camera and the pan head; and the operating-side transmitter-receiver for modulating and transmitting control signals based on an input from a control input section, receiving and demodulating the signal from the camera-side transmitter-receiver, and supplying the demodulated signal to an operating-side display. First-direction and second-direction control signals are input through the control input section. A two-direction detector outputs a detection signal when the first-direction and second-direction control signals are simultaneously output. A time-division clock oscillator produces time-division clock when supplied with the detection signal. A tone pulse oscillator receives the first-direction and second-direction control signals, and outputs tone pulse signals corresponding to the control signals in synchronization with the time-division clock. A tone pulse signal discriminator receives the tone pulse signals, and supplies the electrically-driven device with control voltages according to the tone pulse signals.
