Abstract

In a camera device including a recording device which records an image signal and an audio signal, the recording device includes a display device which indicates that the recording device is in the audio signal recording period. When the display device is composed of a sound generating medium, the display device and the sound generation medium are operated alternately so that sound by the sound generating medium does not affect the audio signal.

Claims

1. An audio recording apparatus comprising:

a) means for converting a sound to an audio signal;

b) means for generating a sound representing a recording condition of said apparatus during a conversion operation of said converting means, said sound generated by said generating means being available to said converting means;

c) means for recording the audio converted by said converting means on a medium; and

d) control means for controlling said converting means such that the audio signal converted by said converting means does not include an audio signal corresponding to the sound generated by said generating means without acoustical isolation, wherein said generating means generates a sound representing the duration of the audio signal recorded by said recording means.

2. An apparatus according to claim 1, wherein said medium comprises a disc medium.

3. An apparatus according to claim 1, further comprising means for generating a recording trigger signal.

4. An apparatus according to claim 3, wherein said generating means generates said recording trigger signal in response to manual operation.

5. An audio recording apparatus comprising:

a) means for converting a sound to an audio signal;

b) means for generating a sound representing a recording condition of said apparatus during a conversion operation of said converting means, said sound generated by said generating means being available to said converting means;

c) means for recording the audio converted by said converting means on a medium; and

d) control means for controlling said converting means such that the audio signal converted by said converting means does not include an audio signal corresponding to the sound generated by said generating means without acoustical isolation; and

e) means for converting an image to a video signal and wherein said recording means records the video signal on the medium.

6. An apparatus according to claim 5, wherein said medium comprises a disc medium.

7. An apparatus according to claim 5, further comprising means for generating a recording trigger signal.

8. An apparatus according to claim 7, wherein said generating means generates said recording trigger signal in response to manual operation.

9. An audio recording apparatus comprising:

a) means for converting a sound to an audio signal;

b) means for generating a sound representing a condition of said apparatus;

c) means for recording the audio signal on a medium; and

d) control means for controlling the sound generated by said generating means so as not to be recorded on the medium, wherein said control means controls said converting means and generating means so that said converting and said generating means do not operate simultaneously and wherein said generating means generates a sound representing the duration of the audio signal recorded by said recording means.

10. An apparatus according to claim 9, wherein said medium comprises a disc medium.

11. An apparatus according to claim 9, further comprising means for generating a recording trigger signal.

12. An apparatus according to claim 11, wherein said generating means generates said recording trigger signal in response to manual operation.

13. An apparatus according to claim 9, further comprising means for converting an image to a video signal and wherein said recording means records the video signal on the medium.

14. An audio and video recording apparatus comprising:

a) means for converting a sound to an audio signal;

b) means for generating a sound representing a condition of said apparatus;

c) means for recording the audio signal on a medium; and

d) control means for controlling the sound generated by said generating means so as not to be recorded on the medium, wherein said control means controls said converting means and generating means so that said converting and said generating means do not operate simultaneously and further comprising means for converting an image to a video signal and wherein said recording means records the video signal on the medium.

15. An apparatus according to claim 14, wherein said medium comprises a disc medium.

16. An apparatus according to claim 14, further comprising means for generating a recording trigger signal.

17. An apparatus according to claim 16, wherein said generating means generates said recording trigger signal in response to manual operation.

18. An audio recording apparatus comprising:

a) means for converting a sound to an audio signal;

b) means for generating a sound representing a condition of said apparatus;

c) means for recording the audio signal on a medium; and

d) means for controlling the sound generated by said generating means so as not to be recorded on the medium, wherein said generating means is generating the sound, said control means inhibits the audio signal converted by said converting means from being transmitted to said recording means, and wherein said generating means generates a sound representing the duration of the audio signal recorded by said recording means.

19. An apparatus according to claim 18, wherein said medium comprises a disc medium.

20. An apparatus according to claim 18, further comprising means for generating a recording trigger signal.

21. An apparatus according to claim 20 wherein said generating means generates said recording trigger signal in response to manual operation.

22. An apparatus according to claim 18, further comprising means for converting an image to a video signal and wherein said recording means records the video signal on the medium.

23. An audio and video recording apparatus comprising:

a) means for converting a sound to an audio signal;

b) means for generating a sound representing a condition of said apparatus;

c) means for recording the audio signal on a medium; and

d) control means for controlling the sound generated by said generating means so as not to be recorded on the medium, wherein when said generating means is generating the sound, said control means inhibits the audio signal converted by said converting means from being transmitted to said recording means, and further comprising means for converting an image to a video signal and wherein said recording means records the video signal on the medium.

24. An apparatus according to claim 23, wherein said medium comprises a disc medium.

25. An apparatus according to claim 23, further comprising means for generating a recording trigger signal.

26. An apparatus according to claim 25 wherein said generating means generates said recording trigger signal in response to manual operation.
