SUMMARY OF THE INVENTION Therefore, according to the present invention, there is provided an audio control type audio / video recording apparatus for controlling an audio / video recording operation by a control audio. Control voice storage means for storing the obtained control voice, voice storage control means for controlling writing and reading of the control voice storage means, and input voice fetched from the voice capture means and stored in the control voice storage means. Voice pattern comparing means for comparing with a control voice, control signal generating means for generating a control signal based on a comparison result of the voice pattern comparing means, and control voice for suppressing a control voice component included in the input voice Suppression means, audio suppression control means for controlling the control audio suppression means based on the control signal, and capturing of video An image capture unit is provided with recording means for recording the video captured by the audio and video capturing means which is output from the control sound suppression means based on the control signal.

In the audio control method of the audio / video recording apparatus, when a control audio is input from the audio capture unit and stored in the control audio storage unit in advance, and when the audio is input from the audio capture unit, one of the control audio is input. Then, the input voice is compared with the control voice stored in the control voice storage means, and when the input voice can be identified as the same, a control signal for commanding the control operation represented by the control voice is generated to generate the control operation. On the other hand, the control audio component of the input audio is suppressed, and the input audio is recorded in the recording unit together with the video captured from the video capturing unit.

Therefore, a control signal for operating the audio / video recording device can be generated by using one audio capturing unit. Further, by suppressing the control sound input from the sound capturing means by the control sound suppressing means, it is possible to prevent the control sound from being recorded in the recording means.

Further, in a voice control type audio / video recording apparatus for controlling a recording operation of voice and video by a control voice, a voice capturing means for capturing voice and a control voice for storing control voice captured by the voice capturing means. A storage means, a voice storage control means for controlling writing and reading of the control voice storage means, and a voice pattern comparison for comparing the input voice fetched from the voice capture means with the control voice stored in the control voice storage means.

Recording means for recording the video captured by the control means, and the control means for instructing the recording means to stop recording. Based on the signal, the input speech for instructing the recording stop is provided a rewind control means to rewind the recording means immediately before the position recorded.

In the audio control method for an audio / video recording apparatus, the control audio including the stop of recording is input from the audio capture unit and stored in the control audio storage unit in advance, and then the audio is input from the audio capture unit. On the other hand, on the other hand, when the input voice is compared with the control voice stored in the control voice storage means and can be identified as the same, a control signal for instructing the control operation represented by the control voice is generated. On the other hand, the input sound is recorded on the recording means together with the video captured from the video capturing means, and when the input voice can be identified as the control voice for instructing the stop of the recording, the recording is performed. Stop recording the means,
Also, the recording position of the recording means is configured to be rewound to just before the position where the input sound is recorded.

Therefore, the sound of the stop control recorded in the recording means is overwritten and deleted at the next recording. Therefore, even if the process of suppressing the control sound from the sound recorded in the recording means is not performed, the sound of the stop control does not remain in the recording of the recording means.
