Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera system for remotely controlling a video camera with a remote commander, a remote commander used for the same, and a video camera.

[0002]

2. Description of the Related Art Conventionally, a video camera system for remotely controlling a video camera with a remote commander has been proposed. In the conventional system, an operation button is provided on the remote commander, and when this operation button is pressed, an operation signal is transmitted. The video camera receives this operation signal, and control is performed according to the received operation signal.

[0003]

However, in the case of a video camera, since it is generally not possible to know the operating state from a remote location, it is unclear whether the operation signal from the remote commander has been accepted. In addition, there is a drawback that even if the operation button is pressed wrongly, the user does not notice it and interferes with shooting.

Therefore, an object of the present invention is to provide a video camera system capable of accurately and surely performing an operation by a remote commander, a remote commander used for the same, and a video camera.

[0005]

A video camera system according to the present invention for achieving the above object includes a microphone for converting a voice into a voice signal and a voice recognition means for recognizing the voice signal and converting the voice signal into an operation signal. And a remote commander having a transmitter for transmitting the operation signal, the receiver receiving the voice signal, and a speaker for converting the voice signal into voice, and a receiver receiving the operation signal. A video camera having a control circuit for instructing control based on the received operation signal, a voice synthesizing unit for synthesizing a voice signal indicating the contents received by the control circuit, and a transmitting unit for transmitting the voice signal. Is.

The remote commander and the video camera according to the present invention for achieving the above object have the above-mentioned configuration.

[0007]

When the operator commands the remote commander to operate by voice, this audio signal is converted into an operation signal and transmitted to the video camera, and the video camera is controlled by this operation signal. The received contents of the video camera are transmitted to the remote commander as an audio signal, and the received contents are output as voice from the speaker of the remote commander. Therefore, the operator can know the content of the operation (the operating state of the video camera) of the control circuit without making a mistake in the content of the operation.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit block diagram of a video camera system showing an embodiment of the present invention. In FIG.
The video camera system is composed of a remote commander A and a video camera B which is remotely operated by the remote commander A.

The remote commander A is provided with a microphone 1, which converts the voice into a voice signal and outputs it to the voice recognition means 2. The voice recognition means 2 has voice patterns such as start, stop, zoom, mode check,
These voice patterns and the input voice signal are compared to identify the operation content from the voice signal, and this is converted into a coded operation signal. When the operation content cannot be identified, an error signal is output to the error LED 3, and when the error signal is output, the error LED 3 lights for a fixed time (several seconds). The operation signal output from the voice recognition means 2 is modulated by the modulator 4 and supplied to the transmitter 5. The transmitter 5 is composed of a light emitting diode and transmits an operation signal as an optical signal.

Further, the remote commander A is provided with a key input section 6 having various operation buttons, which can be operated by the operation buttons. The operation signal of the key input unit 6 is output to the code circuit 7, where it is encoded and supplied to the modulator 4.

Further, the remote commander A has a receiving section 8
Is provided, and the receiving section 8 is configured by a photodiode. The audio signal received by the receiver 8 is demodulated by the demodulator 9 and supplied to the speaker 10.

On the other hand, the video camera B is provided with a receiving section 11 for receiving an operation signal, and the receiving section 11 is composed of a photodiode. The operation signal received by the receiver 11 is demodulated by the demodulator 12 and supplied to the microcomputer 13, which is a control circuit. The detection circuit 14 checks the tape remaining amount, the battery remaining amount, etc., and outputs these detection data to the microcomputer 13.

The microcomputer 13 controls the recording / reproducing system circuit 15, the servo system circuit 16 and the like based on the operation signal and the detection data. When the microcomputer 13 accepts the operation signal, the microcomputer 13 outputs the received contents (video camera operating state), and the mode check signal, the current control contents (video camera operating state) are output to the voice synthesizer 17. ..

The voice synthesizing means 17 synthesizes a voice signal indicating the contents of reception or control, and outputs this voice signal to the modulator 18. The voice signal is modulated by the modulator 18 and is transmitted by the transmitter 19
Is supplied to. The transmitter 19 is composed of a light emitting diode and transmits a voice signal as an optical signal.

When the microcomputer 13 receives an operation signal indicating the generation of a sound effect, it outputs a control signal to the sound effect ROM 20 to read a desired sound effect. ROM20 for sound effects
The voice signal such as the words "2 shots", the word "Kampai", the melody of the wedding march, etc. is stored as an interesting sound effect, and this voice signal is selectively read. The read audio signal is output to the modulator 18 via the D / A modulator 21.

The operation of the above configuration will be described below. For example, when the photographer makes a voice of "start" into the microphone 1 of the remote commander A, the voice recognition means 2 recognizes the operation content from the voice signal, and the operation signal corresponding to this is transmitted from the transmitter 5. When the receiver 11 of the video camera B receives this operation signal, the operation signal is taken into the microcomputer 13. Then, the microcomputer 13 outputs a control signal to the recording / reproducing system circuit 15, the servo system circuit 16, etc., and the video camera B enters the recording mode.

Further, the microcomputer 13 outputs to the voice synthesizing means 17 that the operation signal "start" has been received. Then, the voice synthesizing means 17 outputs a voice signal "start", and the voice signal is transmitted from the transmitter 19. When the receiving unit 8 of the remote commander A receives this voice signal, the speaker 10 outputs a voice of "start". The voice of this start allows the photographer to know that the video camera B has started recording.

When the photographer makes a sound of "mode check" into the microphone 1 of the remote commander A, the mode check signal is taken into the microcomputer 13 in the same manner as above. Then, when recording is currently being performed, the microcomputer 13 outputs the control content of the recording mode (the operating state of the video camera B) to the voice synthesizing means 17, and the current control content is output from the speaker 10 of the remote commander A in the same manner as above. Is output by voice. Therefore, the photographer can know the operating state of the video camera B without looking through the viewfinder of the video camera B, and will not make an operation mistake.

The above operation can also be performed by operating the operation button of the key input unit 6 of the remote commander A. When the microcomputer 13 of the video camera B receives the operation signal, the same operation as described above is performed. A voice such as "start" is output from the remote commander 10.

In this embodiment, the operation of the video camera B itself is remotely controlled. However, if the pan / tilt for changing the orientation of the video camera B is also operated, it becomes more convenient for photographing. .. Further, the microphone 1 of the remote commander A can be used as the microphone of the video camera B by arranging the voice uttered by the microphone 1 of the remote commander A to be recorded on the tape of the video camera B.

In this embodiment, the transmission / reception between the remote commander A and the video camera B is carried out by using an optical signal, but it may be carried out by using an ultrasonic wave or the like.

[0022]

As described above, according to the video camera system of the present invention, it is possible to transmit and receive in both directions between the remote commander and the video camera, and the microphone of the remote commander instructs the operation by voice. When the video camera accepts this operation command, it is configured to output a response audio signal and output it from the speaker of the remote commander, so there is no operation mistake like the operation button and the video camera receives the operation signal of the remote commander. Since it is possible to clearly know whether or not this has been done, there is an effect that the remote operation of the video camera can be performed accurately and reliably.

Further, the remote commander and the video camera according to the present invention enable the above-mentioned accurate and reliable remote operation.
