Japanese Patent Application Laid-Open No. Hei 9-23122 discloses an information display device that provides a handling explanation by voice.

[0005]

However, in the above-described conventional video camera and other electronic devices, the operation description can be reproduced without any trouble at the time of reproduction.
Since the reproduced operation guide is collected by the recording microphone, it cannot be used at the time of recording.

The present invention has been made in view of the above points, and an object of the present invention is to propose a camera-integrated recording / reproducing apparatus that can use an operation guide by voice at any operation.

SUMMARY OF THE INVENTION In order to solve this problem, a camera-integrated recording / reproducing apparatus according to the present invention records a video signal and an audio signal captured by a camera unit during recording on a recording medium by a recorder unit. In a camera-integrated recording / reproducing apparatus for reproducing a video signal and an audio signal recorded on a recording medium by a recorder unit during reproduction, an audio synthesizing means for reproducing information on the camera-integrated recording / reproducing apparatus and synthesizing the information with the audio signal is provided. It is provided.

According to the camera-integrated recording / reproducing apparatus of the present invention, the following operations are performed. The recording / reproducing apparatus with a built-in camera records a video signal and an audio signal captured by a camera unit at the time of recording on a recording medium by a recorder unit, and reproduces the video signal and the audio signal recorded on the recording medium by the recorder unit at the time of reproduction. . The voice synthesizing means reproduces information on the camera-integrated recording / reproducing device and synthesizes the information with the audio signal.

During the reproduction operation, when the operator inputs and instructs the output request of the voice guide, the control means supplies a control signal of the guide output to the voice synthesis means. As a result, a voice synthesis signal is output from the voice synthesis means as a guide output, and the guide voice is reproduced.

During the recording operation, when the operator instructs to input a voice guide output request, the control means supplies a control signal for guide output to the voice synthesis means. At this time, the control means controls so that the level of the audio signal to be recorded matches the level of the audio output signal of the guide output. The recorder unit collects the synthesized voice of the voice to be recorded and the output of the guide output. The level of the audio signal collected by the recorder unit is detected by the control unit.

[0011] A transfer function from the output of the speech synthesis signal from the speech synthesis means to the arrival at the recorder section is multiplied by the speech synthesis signal from the speech synthesis means. The speech synthesis signal is subtracted from the speech signal collected by the recorder section to cancel the speech synthesis signal, and only the speech signal to be recorded is supplied to the recorder section. In this manner, the guide voice acts so as to be prevented from being collected and recorded by the recorder unit during recording.

In addition, automatic shooting is performed continuously for 5 seconds.
In the case of the second photographing mode or the like, the operator is signaled with a single sound of “pip-pip-pip-pip” for 5 seconds.

In this case, the handling explanation is made such that the handling explanation data is stored in advance in the memory inside the speech synthesis circuit 61 or the microcomputer 62, and the speech synthesis processing is performed in response to the output request and then output. I do. The microcomputer 62 guides the photographing situation by using the power supply voltage of the power supply block 9 of the camera-integrated disk recorder and the mechanical deck / OP.

The guide output configuration block of the instruction for handling by speech synthesis of the recording system thus configured operates as follows. During the recording operation, when the operator instructs to input a voice guide output request using an operation switch (not shown), the microcomputer 62 supplies a control signal for guide output to the voice synthesis circuit 61. At this time, the microcomputer 62 determines the level of the audio signal from the level detection circuit 75 and the
The control signal to the voice synthesizing circuit 61 and the control signal to the variable amplifier 72 are supplied so that the level of the voice synthesizing signal from 1 coincides.

The converter 73 converts the analog audio signal amplified by changing the level by the variable amplifier 72 into a digital audio signal. The level detection circuit 75 detects the level of the digital audio signal and supplies the detected level signal to the microcomputer 62.

The transfer function circuit 77 outputs the speech synthesized signal from the speech synthesis circuit 61 from the speaker 65 to the microphone 7.
The transfer function until it reaches 0 is multiplied by the speech synthesis signal from the speech synthesis circuit 61 and output. Note that this transfer function is obtained by measuring the time required for the synthesized voice output from the speaker 65 to reach the microphone 70 in advance, experimentally obtaining and storing it. The digital mixer 76 cancels the voice synthesis signal by subtracting the voice synthesis signal from the transfer function circuit 77 from the digital voice signal from the A / D converter 73 and supplies only the voice signal of the digital data to be recorded in the recording system. I do. In this way, it is possible to prevent the guide voice from being collected and recorded by the microphone 70 during recording.
