Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording apparatus for recording audio information and video information to which audio information is added by using a disk-shaped recording medium such as an optical disk or a magneto-optical disk.

[0002]

2. Description of the Related Art Conventionally, magnetic tapes have often been used as recording media for video camera recorders. A semiconductor memory is generally used as a recording medium of an electronic still camera for capturing a still image. On the other hand, in recent years, as recording densities of optical discs and magneto-optical discs have increased and drive devices for these recording media have been downsized, optical discs and optical discs have been used as recording media for video camera recorders and electronic still cameras. A disk using a disk-shaped recording medium such as a magnetic disk is being put to practical use.

On the other hand, some electronic still cameras have come to record not only image information but also audio information. For example, there is an electronic still camera provided with audio input means such as a microphone so that a still image can be recorded for several seconds to several tens of seconds at the same time.

[0004]

A recording apparatus using a disk-shaped recording medium such as an optical disk or a magneto-optical disk requires a complicated servo operation, unlike a recording apparatus using a recording medium such as a magnetic tape. Some servo operations are not always continuous during recording. That is, for example, in the case of a magnetic tape,
The servo control for stabilizing the running of the magnetic tape and the servo control for the rotation of the rotary head drum for recording a signal on the magnetic tape may be stabilized, and these servo controls are basically continuous during the recording operation. Done.

On the other hand, in the case of an optical disk, for example, a spindle servo for stabilizing the rotational speed of the disk, a thread servo for setting a position in the disk radial direction of an optical pickup for generating a laser beam for irradiating the disk, and A tracking servo that sets the irradiation position of the laser beam on the track on the disk, a focus servo that focuses the laser beam on the signal recording layer of the disk, etc. are required, and complicated processing is required as the processing required for recording It is.

Also, some servo controls required for these disk recording processes may be intermittent operations. For example, in the case of a sled servo for moving an optical pickup in the radial direction of a disk, it is often necessary to largely move the pickup when first moving the optical pickup to a target track position. Further, after the recording is started, if the recording track is divided into a plurality of distant places on the disc, a large thread feed may occur temporarily. In addition, the focus servo generally involves a relatively large movement when initially focusing on the signal recording surface of the disc, and once the focus is achieved, the servo continues to focus on the focus position. Control may be performed.

[0007] When there is such a non-continuous servo operation, noise generated by the servo operation is generated.
However, there is a problem that annoying noise is added to the sound to be recorded by mixing into the sound being recorded. That is, for example, even in the case of a video camera using a conventional magnetic tape as a recording medium, noise of a motor or the like that drives a tape traveling system,
Although it is mixed into the sound being recorded at a certain level, such noise is noise that is continuously mixed at a substantially constant level from the start to the end of recording, and is not very annoying.

On the other hand, since the noise generated by the servo operation of the disk is not always continuous as described above, the noise intermittently mixes with the sound being recorded. Would be unpleasant. In particular, at the start of recording, it is necessary to move the optical pickup to a target recording position on the disc to focus on the track at that position, and relatively loud noise is generated. Is mixed.

FIG. 5 shows a process in which a conventional electronic still camera using a disk as a recording medium captures a sound for several seconds at the same time as capturing a still image and records the captured image information and audio information on the disk. FIG. 5 is a timing chart showing an example of the time series. FIG. 5A
Is a command sent from the control unit of the camera to the disk drive unit that drives the disk, FIG. 5B shows an operation executed under the control of the control unit, and FIG. 5C shows an operation performed by the user.

[0010] In this example, when the camera is operating in a state where it can take a picture, the disc drive section shown in FIG.
As shown in (1), the servo is turned on to perform servo control on the loaded disk. Then, when the user operates the shutter button, one image (one frame or one field) of still image information is captured and recorded at that timing, and at the same time as the image is captured, the voice capture is started. A 10-second sound is recorded. Therefore, as shown in FIG. 5C, at the timing when the user completely presses the shutter button (so-called full-pressed state), as shown in FIG. 5B, the input of the sound from the microphone or the like built in the camera is started. , The voice input lasts for 10 seconds. For image import,
Although not shown in FIG. 5, at the timing when the user completely presses the shutter button, a process of capturing one still image by the photographing unit is executed.

[0011] Then, when the voice input is completed, as shown in FIG. 5B, a process of acquiring file information is executed under the control of the control unit. The process of acquiring the file information is, for example, acquiring information on which address (track) of the disc the information should be written. After this file information is obtained, the captured image information is
Perform image conversion processing to convert to a format for recording,
Obtain image information and audio information to be written on the disc.

When the processing is completed so far, a recording process for writing the prepared image information and audio information to the disc is executed. That is, as shown in FIG. 5A, the control unit sends a write command (WHITE) to write information on a predetermined track of the disk. This writing is performed in units of one packet. For example, when the image information and the audio information here are composed of two packets, as shown in FIG. Write to disk. Then, after the writing is completed, a command of the synchronizing cache is sent to the drive, data write completion processing of the cache memory is performed, and when a command indicating that the processing has been returned is returned to the control unit, the write processing is terminated. Even after the writing process is completed, the servo control of the disk remains on as long as the camera stands by in a state where it can capture images.

As described above, in the conventional electronic still camera, during the audio input shown in FIG. 5B, the servo operation of the disk is performed, and noise generated by the servo operation at that time is generated by the audio. There was a problem that it was picked up by a microphone that performs input.

The present invention has been made in view of such a situation, and when recording information including sound using a recording medium, noise generated by driving the medium or the like is recorded. It is an object of the present invention to prevent the audio information from being mixed into the received audio information.

[0015]

According to the present invention, there is provided input means for inputting voice information, storage means for storing voice information input to the input means, and voice input to the input means and stored in the storage means. Recording means for recording information on a recording medium;
A servo means for setting the recording medium in a state in which recording can be performed by the recording means; and a predetermined servo operation by the servo means is not performed while inputting audio information for recording by the input means. And control means for controlling the recording means to record the sound information stored in the storage means on a recording medium while executing the servo operation by the servo means after the input of the sound information in units.

According to the invention, while one unit of audio information is being input by the input means, the servo means does not execute a predetermined servo operation. Therefore, noise generated due to the servo operation is not included in the sound being input by the input means, and it is possible to effectively prevent noise accompanying the servo operation from being mixed into the recorded sound.

[0017]

1, MPEG2, MPEG4, etc.). If the video data is still image data, JPEG (Joint
Data encoded by an encoding method suitable for still image data, such as the Photograhic coding Expers Group (Photograhic coding Expers Group) method. The video data and the audio data encoded by the compression encoding circuit 18 are stored in the memory 14 until a reading instruction is given.

When there is a read instruction from the user interface control microcomputer 30 or the like, the memory 1

01 is performed to record video data and audio data. The configuration of the CD-R drive unit 100 will be described later.

Processing for recording by the recording apparatus of this embodiment is as follows.
It is executed based on the control of the user interface control microcomputer 30. That is, the user interface control microcomputer 30 sends a command for controlling a photographing operation, a voice input operation, a recording operation on a medium, and the like to each unit via the bus line 19 so that each processing unit executes the corresponding operation. It is.

User interface control microcomputer 30

A voice input operation, a recording operation on a medium, and the like are executed. The shutter operation unit 40 includes a shutter button 4
The shutter button 41 includes a shutter half-press detection switch 41a that detects a state where almost half of the shutter button is pressed, and a shutter full-press detection switch 41b that detects a state where the shutter button is almost completely pressed. It is arranged.
When the shutter button 41 is pressed, a half-pressed state is first detected by the shutter half-press detection switch 41a, and then a fully-pressed state is detected by the shutter full-press detection switch 41b. The shutter half-press detection switch 41a functions as a so-called shutter lock switch, and is a switch for starting a process at a previous stage for capturing an image or the like.
As the processing at the previous stage here, for example, an operation of locking the focus position in the optical system can be considered. The shutter full-press detection switch 41b functions as a so-called shutter switch, and is a switch for starting capture of an image or the like.

Although not shown in FIG. 1, a monitor or a viewfinder for displaying an image obtained by photographing with the photographing system or displaying an image recorded on the mounted CD-R 101 may be provided. good.

Next, the configuration of the CD-R drive unit 100 will be described with reference to FIG. CD-R drive unit 1
The disk 101 mounted on the disk drive 00 is driven to rotate by a spindle motor 102, and the laser light emitted from the laser light source 111 in the optical pickup 110 irradiates the signal recording surface to record data on the disk and reproduce the recorded data. Is performed. The radial position of the disk 101 of the optical pickup 110 is
It is determined by driving.

As for various servo controls required at the time of recording and reproduction, the detection output of the return light detection unit 112 in the optical pickup 110 is processed by the RF processing unit 104, and the servo control is performed within the RF processing unit 104. To obtain a good signal component. That is, a focus error signal FE, a tracking error signal TE, a clock component FMCK, and the like are obtained, and these signals are supplied to the servo processing unit 105. The servo processing unit 105 controls the servo processing so that each signal converges within a predetermined range. Generate control data. The servo control data generated by the servo processing unit 105 is supplied to each of the servo driving units 121 to 124 via the analog filter unit 109.

More specifically, a focus drive unit 121 for driving a focus coil for performing focus adjustment of an optical system in the optical pickup 110, and adjustment of a track position of laser light emitted from the optical pickup 110 (tracking adjustment) A tracking drive unit 122 that drives a tracking coil that performs
3 drives the optical pickup 110 to set the position of the optical pickup 110 in the radial direction of the disk, and the spindle drive unit 1 controls the rotational speed of the disk 101.
24, a servo control loop is formed by the driving of each of the drive units 121 to 124. Each servo control using the servo processing unit 105 is executed according to an instruction from the recording control unit 20.

A mirror signal, which is a signal proportional to the reflectance of the signal from the disk generated by the RF processing unit 104, is supplied to the mechanical control unit 107. The mechanical control unit 107 determines the number of tracks straddled when the optical pickup 110 is threaded from the state of the supplied mirror signal, and supplies the recording control unit 20 with data indicating the radial position of the optical pickup 110. I do.

In the recording apparatus of the present embodiment, after performing the above-described servo control, recording on the disk 101,
Reproduction from the disc 101 is executed. That is, the video data and the audio data to be recorded on the disc are supplied from the recording control unit 20 to the signal processing unit 106 to be signals to be supplied to the optical pickup 110, and this signal is supplied to the optical pickup 110, It is recorded on a predetermined track on the signal recording surface of the disc. The signal read from the signal recording surface of the disk by the optical pickup 110 is supplied to the signal processing unit 106 via the RF processing unit 104, and is converted into reproduction data of a predetermined format. Via the recording control unit 20,
This is supplied to the other blocks of the device.

The CD-R drive section 100 of the present embodiment is provided with an ATAPI (At Attachment Packet Interface).
ce), which is a standard interface for communicating with other blocks.
The commands that the player receives for disc recording and playback are:
This is a command specified by the ATAPI.

Next, in the CD-R drive section 100, the servo processing section 10 is controlled based on the control of the recording control section 20.
The state in which the servo control is executed at 5 or the like will be described with reference to the flowchart of FIG. First, the recording control unit 20
It waits for an access command from the user interface control microcomputer 30 or the like (step S11), and determines whether or not the access command has been received (step S11).
12). If the access command has not been received, the process waits in standby at step S11. Then, when the access command is received, it is determined whether or not the disk is servoed as the current operation status (step S13). If the servo is not operating, a command to apply the servo is generated. Then, each servo control is executed by the servo processing unit 105 (step S1).
4). In the case of this example, the command received by the recording control unit 20 in a state where the servo is not operated includes a command for executing a seek operation. When this command is received, the processing in step S14 is performed. Then, the servo is turned on. However, when a command to execute a seek operation has already been received in the servo-on state, only the seek operation (operation to move the pickup to the corresponding position) specified by the command is performed.

When it is determined in step S13 that the servo operation has already been performed, and when a command for applying the servo is generated in step S14, the process proceeds to step S1.
The process proceeds to step S5, where a command for executing an operation corresponding to the access command received in step S12 is sent to the mechanical control unit 107 in the drive unit 100 to execute the corresponding operation. Then, the process waits until the operation is executed (step S16). Then, step S12
It is determined whether or not the command received in (1) is a seek operation (that is, an operation of performing thread feed for moving the optical pickup in the radial direction of the disk) to obtain a target radial position (track position) ( Step S1
7). When it is determined that the seek operation is performed,
It returns to step S11.

If it is determined in step S17 that the operation is not a seek operation, the count of a timer set in the recording control unit 20 is started (step S1).
8). Then, the count value of the timer is counted up in synchronization with the clock supplied to the recording control unit 20 (step S19). Here, it is assumed that the count-up is performed in units of 1 ms. Then, it is determined whether or not the count value of the timer has reached X [ms] (step S2).
0). This X [ms] is, for example, 120 [ms].

Then, in step S20, the count value becomes X
When it is determined that the time has exceeded [ms], a command to turn off the servo operation is issued (step S21), the servo control being executed by the servo processing unit 105 in the drive unit 100 is turned off, and the process proceeds to step S11. Return to judgment.

If it is determined in step S20 that the count value of the timer has not exceeded X [ms], it is determined whether a new command has been received (step S22). Step S19
And the timer continues counting up. When a new command is received in step S22,
The timer stops counting up, resets the count value to the initial value, and returns to step S15.

Turning off the servo operation in step S21 is a process of stopping the servo control. Therefore, for example, the rotation of the disk by the spindle motor 102 is on standby while being performed. However, since servo control is not performed, there is a high possibility that the rotation speed of the disk by the spindle motor 102 is not within a certain range required for recording and reproduction. Here, although not shown in this flowchart, when no command is supplied to the recording control unit 20 for a predetermined time (for example, 30 seconds) after the servo is turned off, the rotation drive by the spindle motor 102 is stopped. It is.

Next, an operation example when a still image is captured by the recording apparatus of this embodiment will be described with reference to the timing chart of FIG. FIG. 4 shows an electronic still camera, which is a recording device of the present embodiment, captures a few seconds (here, 10 seconds) of audio at the same time as capturing a still image, and records the captured image information and audio information on a disc. FIG. 6 is a timing chart illustrating an example of a process to be performed in a time series. FIG. 4A
FIG. 4B shows a command sent from the user interface control microcomputer 30 or the like to the recording control unit 20 for driving the disk, and a disk drive operation executed in response to the command. FIG. FIG. 4C shows an operation performed by the user.

In this example, as shown in FIG. 4A, the disk drive unit 100 is normally in a servo-off state, as shown in FIG. 4A. However, there is a possibility that only rotation drive of the disk by the spindle motor is performed, but even in this case, servo control of the rotation speed is not performed, but rough speed control for rotating at a certain speed is performed. Only.

In this state, as shown in FIG. 4C, at the timing when the user interface control microcomputer 30 detects that the user has completely pressed the shutter button 41 and the shutter full-press detection switch 41b is turned on, the user interface control microcomputer 30 turns on the CCD. One frame (one frame or one field) of still image information output from the imager 12 is captured, and as shown in FIG. 4B, capture of the sound picked up by the microphone 15 for 10 seconds is started.

When the voice input for 10 seconds is completed, a process for acquiring file information is executed under the control of the user interface control microcomputer 30, as shown in FIG. 4B. The process of acquiring the file information is, for example, acquiring information on which address (track) of the disc the information should be written.

In the case of this example, at the time of the process of acquiring the file information, as shown in FIG. 4A, the user interface control microcomputer 30 sends a command for causing the recording control unit 20 to execute a seek operation. The instruction for the seek operation in the command at this time is an instruction to move the optical pickup to an address (track) determined to be writable with the acquired file information.

By sending a command to execute this seek operation, the processing of step S14 in the flowchart of FIG. 3 is executed, the servo section is turned on in the drive section 100, and the optical pickup is moved to the corresponding track of the disk. Wait for writing. At this time, the position of the optical pickup in the radial direction of the disk is not only set to the designated position by the thread servo, but also the rotation speed of the disk is controlled to be constant by the spindle servo, and the tracking control is While following the designated track, the focus servo brings the laser beam into focus on the signal recording surface of the track that has followed. In this state, it waits until information to be written on the disc is sent.

After the file information is obtained, the user interface control microcomputer 30 performs image conversion processing and audio conversion processing for converting the captured image information and audio information into a recording format, and outputs the obtained information to the disc. Obtain image information and audio information to be written.

When the processing is completed up to this point, a recording process for writing the prepared image information and audio information to the disc is executed. That is, as shown in FIG. 4A, the control unit sends a write command (WHITE), sends image information and audio information to the disk drive unit 100, and causes the disk to write information. This writing is performed in units of one packet,
For example, when the image information and the audio information here are composed of two packets, as shown in FIGS. 4A and 4B, two write commands are sent, and the information of two packets is written to the disk by the intermittent operation.

When writing is performed by such an intermittent operation, the time from the end of one writing to the start of the next writing is, for example, several tens [ms]. But it is set not to exceed 120 [ms]. In the process of acquiring the file information, the time from sending the seek command to the recording control unit 20 to sending the write command is, for example, about 990 [ms] on average, and about 1330 [ms] at maximum. .

After the writing is completed, the command of the synchronizing cache is sent to the recording control unit 20, the data write completion processing of the cache memory is performed, and when the command indicating that the processing is completed is returned to the control unit, the writing is completed. The process ends. After this writing process is completed,
If no command is supplied for 120 [ms], FIG.
Based on the determination in step S20 shown in the flowchart of FIG. 7, the issuance of the servo-off command in step S21 is issued, and the operation returns to the servo-off state. However, in this state, the disk remains rotating without being servo-controlled. Regarding the rotation of the disk, in the case of this example, if no command is sent for 30 seconds after the last command is issued, the rotation is stopped.

By performing the processing as described above, the microphone 1 can be used during shooting in the still image shooting mode with sound.
5 does not pick up noise generated due to the servo control of the disk 101 as a recording medium, so that good voice recording without noise can be performed. That is, the servo control of the disk is normally in an off state, and the servo operation is in an on state after the audio capturing is completed, so that the noise generated by the thread feed of the optical pickup or the rotation drive of the spindle motor is normally used. However, it does not mix with the recorded audio.

In this example, if no command is supplied for 120 [ms] after recording on the disk, the servo is automatically returned to the off state. It will wait by servo off. Therefore, no useless servo operation is performed,
Useless operation noise does not occur with the servo operation, and the power consumption required for the servo operation can be reduced.

In the above-described embodiment, the recording on the disk as the recording medium is performed intermittently in units of one packet. However, the time until the servo is turned off is intermittently recorded. By setting longer than the maximum time, during intermittent recording in 1 packet unit,
Servo off does not occur. When the seek command is sent and the servo is turned on, the servo is not turned off even if the period of no command has passed for 120 [ms] or more. It is performed continuously and a good servo control state is maintained.

Although the case where the sound is recorded simultaneously with the photographing of the still image has been described here, the present invention can be applied to the case where the moving image is photographed and the continuous sound is recorded simultaneously with the photographing. However, in order to perform the processing of this example, it is necessary to temporarily store video data and audio data in storage means such as a memory, and then turn on the servo control to record the stored data on a medium. Since it is necessary, the continuous time that can be photographed is limited by the capacity that can be temporarily stored by the means for temporarily storing. When a large-capacity storage device such as a hard disk device is used as the temporary storage device, the processing of the present invention can be applied to long-time continuous shooting.

Further, in the above-described embodiment, all the servo controls related to the disk drive are controlled to be turned on / off continuously after the write operation. However, only a part of the servo controls may be controlled. good. For example, the spindle servo control for driving the disk to rotate may be always on, and the thread servo for controlling the position of the pickup may be on / off controlled.

Further, in the above-described embodiment, an example is described in which an optical disk called a CD-R is used as a disk-shaped recording medium. Of course, the present invention can also be applied to a case where audio data and the like are recorded using a disk-shaped recording medium having another configuration. Further, as long as the medium requires the same servo control, the present invention can be applied to a recording apparatus using a medium other than a disk-shaped recording medium as a recording medium.

Also, in the above-described embodiment, the processing in the case where the camera device records the audio simultaneously with the video on the recording medium has been described. However, the audio recording device records only the audio on the disk-shaped recording medium or the like. In this case, it is needless to say that the present invention can also be applied to noise prevention processing accompanying the servo operation.

[0055]

According to the first aspect of the present invention, while one unit of audio information is being input by the input means, a predetermined servo operation is not executed by the servo means.

By doing so, the servo operation is performed only while information is being recorded on the medium, the servo operation is performed at the minimum necessary, and the occurrence of noise due to the servo operation is minimized And the power consumption of the recording apparatus can be reduced accordingly.

According to the invention described in claim 6, in the invention described in claim 5, when recording of one unit of audio information on the recording medium by the recording means is performed in a plurality of times, the division is performed. When a plurality of final recordings are completed, the predetermined servo operation by the servo means is turned off, so that when the recording is divided into a plurality of times, the servo operation is repeatedly turned on and off. Is gone,
It is possible to satisfactorily record information on a medium by dividing it into a plurality of times.

According to the invention described in claim 7, in the invention described in claim 1, the input means is means for inputting image information of a still image or a moving image together with audio information, and the recording means is a recording medium. By recording image information together with audio information, it is possible to perform good audio recording without noise when recording an image taken and recording audio with an electronic still camera or video camera. .
