Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an image and audio recording device.

[Prior Art] As a device capable of simultaneously recording images and audio, there is a video recording device.
In addition to tape recorders, there are still video cameras. In still video cameras, the audio is time-compressed, flags and control codes are added, and then FM
It is modulated and recorded on one track of a still video floppy. The control code includes information on the time compression rate and the track number of the corresponding video track, which enables time expansion during playback and simultaneous playback of the corresponding videos.

[Problems to be Solved by the Invention] Conventionally, the above-mentioned still video cameras are equipped with only one microphone for human voice input, and therefore, when the microphone is directed toward the subject, the photographer has to manually input the microphone. There was a problem in that the narration could not be recorded clearly, and conversely, when the microphone was directed toward the photographer, the voice of the subject could not be clearly recorded.

To solve this problem, it would be possible to install a microphone for the subject and a microphone for the photographer (narration microphone), and to be able to switch between them using a switch or adjust the mixing ratio of these microphone outputs, but such a device However, if the photographer's microphone is selected by the changeover switch, or if the mixing ratio is not large enough to record the subject's audio, self-timer shooting or remote control (hereinafter referred to as remote control) may be used. ) When photographing, there is a problem in that the voice of the subject cannot be clearly recorded.

Therefore, an object of the present invention is to provide a recording device that solves these problems.

[Means for Solving the Problems] A recording device according to the present invention includes an imaging means, a plurality of audio input means having mutually different characteristics, and records an image taken by the imaging means and/or an input sound by the audio input means. It is characterized by comprising a recording means for recording on a medium, and a control means for setting and controlling each of the above-mentioned audio input means according to the imaging mode. The present invention also provides an imaging means, a plurality of audio input means having characteristics corresponding to mutually different imaging modes,
a recording means for recording on a recording medium an image taken by the imaging means and/or an input sound by the audio human power means; and a recording means for recording on the recording medium the output of the audio input means having characteristics according to the imaging mode at the time of predetermined photographing. and warning generating means for generating a predetermined warning when the system is not configured to operate normally.

[Function] With the above means, during predetermined shooting such as remote control shooting or self-timer shooting, the setting that gives priority to the audio from the subject side is changed, and a warning requesting such a change is issued. Therefore, voice recording will not fail.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a block diagram of the configuration of an embodiment of the present invention, and FIG. 2 shows an operation flowchart thereof.

System control circuit 54 using a microcomputer etc.
After initialization, the controller sequentially determines whether or not the remote control release switch, self-timer switch 60, and release switch 62 included in the remote control transmitter 58 have been pressed (S1, S2, and S6). ). Remote controller·
Information as to whether the release switch has been pressed is sent to the system control circuit 54 via the remote control receiver 56.

When the remote control release switch is pressed (Sl)
, and when the self-timer switch 60 is pressed (S
In step 2), it is checked whether the selection by the microphone changeover switch 64 is the subject side microphone 10 (S3), and if the subject side microphone 10 is selected, video and audio recording is executed. If 10 is not selected, connect the switch 18 to the a contact side and turn the microphone 1 on the subject side.
Select 0 (S4), set the microphone switching flag indicating microphone switching (S5), and execute video and audio recording (S7).

If the release switch 62 is pressed without pressing the remote control release switch or the self-timer switch 60 (S6), video and audio recording is immediately executed (S7).

When images and audio are thus recorded on the magnetic disk 48 (S7), the system control circuit 54 checks the microphone switching flag (S8), and if it is set, switches the switch 18 to the b contact side (S9). ).

5I will end when the main switch (not shown) turns off.
O), otherwise return to Sl and repeat the above routine.

The video and audio recording operation will be briefly explained. The system control circuit 54 rotates the magnetic disk 48 at a predetermined speed,
The magnetic head 46 is moved to a predetermined track. The PG detection coil 50 detects the rotational phase of the magnetic disk 48, and the timing signal generation circuit 52 generates a timing signal of the rotational phase. The system control circuit 54 sends the timing signal to the clock generation circuit 76 to cause the image sensor 70 to output an image signal. The output of the image sensor 70 is recorded on the magnetic disk 48 by a process circuit 72, a pre-emphasis circuit 74, a switch 40, an FM modulation circuit 42, a recording amplifier 44 and a magnetic head 46. After this recording is completed, the system control circuit 54 moves the magnetic head 46 to another track for recording audio.

The audio signal output from the microphone 10.14 is amplified by an amplifier 12.16, selected by a switch 18, and applied to an encoder 20. The output of the encoder 20 is sent to the A/D converter 22
The data is digitized and stored in the memory 24. When audio data for a predetermined period of time is stored in the memory 24, it is read out at a clock according to a predetermined compression ratio, and converted back into an analog signal by the D/A converter 26. A memory control circuit 28 controls writing and reading of the memory 24 and A/D.
Controls the sampling clocks of converter 22 and D/A converter 26. That is, A/D converter 22, memory 24
, the D/A converter 26, and the memory control circuit 28 function as a time axis compression circuit.

The output of the D/A converter 26 is applied to an adder 32, and a flag generation circuit 36 and a control code generation circuit 38
generate the above-mentioned flag and control code, respectively, and the adder 32 superimposes and adds these. Adder 32
The output of the pre-emphasis circuit 34, switch 40, F
The signal is applied to the magnetic head 46 via the M modulation circuit 42 and the recording amplifier 44, and is recorded on the magnetic disk 48.

In this manner, in the embodiment shown in FIG. 1, in the case of remote control photography or self-timer photography, the sound from the subject side microphone 10 is recorded regardless of the microphone changeover switch 64.

In the embodiment shown in FIG. 1, either the subject side microphone 1o or the photographer side microphone 14 is selected and used, but the present invention can also be applied to a configuration in which the outputs of both microphones 10 and 14 are mixed. . FIG. 3 shows a block diagram of the structure of the modified embodiment, and FIG. 4 shows its operation flowchart. The difference from FIG. 1 is that a mixing circuit 78 is provided in place of the switch 18, and a mixing ratio setting switch 80 is provided in place of the microphone changeover switch 64. Other circuit elements are the same as in FIG. 1 and are given the same reference numerals.

The operation of the modified portion of FIG. 3 will be explained with reference to FIG.

Similar to FIG. 2, when the remote control switch or self-timer switch 60 is pressed (SLl.

12), the system control circuit 82 checks the mixing ratio set by the mixing ratio setting switch 80 (51).
3) If the setting is not such that the audio from the subject side microphone can be clearly recorded, increase the mixing ratio to the subject side microphone 10 or set it to only the subject side microphone 10 (514), set the mixing switching flag (515), and record. Execute (S17). Also, if there is no need to change the mixing ratio (513) and if the release switch 62 is pressed (S16), recording is executed immediately (SI?).
.

After recording (S17), the mixing ratio switching flag is checked (818), and if it is set, the mixing ratio is returned to its original state (S19). The subsequent steps are the same as in FIG.

In this way, in the case of remote control photography or self-timer photography, audio recording can be performed with the mixing ratio increased toward the subject, regardless of the setting of the microphone/mixing ratio setting switch.

FIG. 5 is a flowchart of changing operations in the configuration of FIG. 1. Specifically, if the remote control release switch or self-timer switch 60 is pressed in a situation where the subject-side microphone 10 is not selected, a predetermined warning is given and recording is not performed (S21). This warning may be a warning by emitting light from the display device 66, a warning by displaying text and graphics, or a warning by voice.

FIG. 6 is an operation flowchart for performing the same operation as FIG. 5 in the configuration of FIG. 3. That is, if the remote control release switch or self-timer switch 60 is pressed in a situation where the microphone mixing ratio is not high for the subject-side microphone 10, a predetermined warning is given as in S21 of FIG. No recording is performed (526).

In the above explanation, only two microphones, the subject-side microphone 1o and the photographer-side microphone 14, are used, but the same applies, of course, to the case where three or more microphones are used. Also, even with one microphone, you can switch the directivity or rotate the direction during remote control shooting or self-timer shooting.
Operate so that the subject's voice can be clearly recorded,
Alternatively, a warning may be generated.

Furthermore, although the explanation has been given using a still video camera as an example, it can also be applied to devices that capture and record moving images, and can also be applied to recording devices that use optical disks, magneto-optical disks, solid-state memory devices, etc. as recording media. can.

[Effects of the Invention] As can be easily understood from the above explanation, according to the present invention, in the case of remote control photography or self-timer photography, the voice of the subject can be clearly heard automatically or by generating a warning. will be able to record.
