[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device capable of recording, for example, a captured image, and a recording method for recording the captured image.

[0002]

2. Description of the Related Art In recent years, digital cameras such as digital still cameras and digital video cameras have become widespread. In these digital cameras, image data of a captured image can be recorded in a built-in recording medium such as a flash memory or a recording medium such as a memory or a disk that can be inserted into the main body. In the present situation, the capacity of these storage media is also being increased, and for example, in the case of still image data, a large number of image data can be recorded and stored. It has become.

Further, as these digital still cameras have been enhanced in function, various photographing conditions such as exposure (shutter speed, aperture) or white balance can be variably set. Those equipped with the function that can do have become popular.
By using this function, the user can set the shooting conditions suitable for the shooting conditions and shoot so that an image closer to his image can be obtained. For example, when shooting a moving subject when watching sports, for example, full-time AF (Auto Focus), high sensitivity, shutter speed priority, etc. are set as appropriate settings, and a still subject is captured. When shooting, settings such as low sensitivity and aperture priority are made.

When the user sets the above-mentioned photographing conditions, for example, a predetermined operation is performed according to a GUI (Graphical User Interface) displayed on a screen such as an LCD (liquid crystal display) provided in the camera body. To be done.

[0005]

By the way, although the higher the number of setting items of the above-mentioned photographing conditions becomes, the higher the function becomes. Become. As a result, for example, a person may miss a photo opportunity.

Further, in the conventional digital still camera, with the increase in the storage capacity as described above,
For example, there is a model capable of recording a very large number of shot images of several hundreds or more on one medium. However, when a large number of image data are recorded on one medium as described above, it is a very difficult task for the user to find a desired one from the hundreds of image data. For this purpose, for example, the concept of group classification by folders may be introduced, and the user may organize the image data in the folder in the medium. In this case, for example, when the number of pieces of image data recorded and recorded has accumulated to some extent, the user moves any image data to any folder by performing a predetermined operation on the digital camera, for example. However, even in such a case, since the operation for storing the image data in the folder is a manual operation, it is troublesome.

[0007]

In view of the above problems, the present invention is configured as a recording apparatus as follows. That is, first, an image pickup means for picking up an image to obtain an image signal, a signal processing means for performing required signal processing on image data obtained based on the image signal obtained by the image pickup means, and the signal processing means. And a recording unit for recording the image data obtained by the method on a predetermined recording medium. Then, the image data recorded on the recording medium can be managed by being divided into groups, and each group is associated with imaging record mode information formed from setting information on one or more imaging record condition items. Management information storage means for storing management information for managing the group and selection means operable for selecting the group are provided, and recording by the recording means is executed. At this time, setting means for setting, to the image pickup means or the signal processing means, the setting content indicated by each setting information forming the image pickup recording mode information associated with the group selected by the selecting means, The image data recorded on the predetermined recording medium by the recording unit should belong to the group selected by the selecting unit. To be managed by, and to include a management information forming means for forming the management information.

According to the present invention, the recording method is as follows. That is, first, a signal processing procedure for performing required signal processing on image data obtained based on an image captured by the image capturing unit, and a recording process for recording the image data obtained by the signal processing procedure on a predetermined recording medium. Make steps and procedures executable. Then, the management information stored in a predetermined storage unit manages the image data recorded on the recording medium by grouping, and each group is formed from setting information about one or more imaging recording condition items. A management procedure for managing the image pickup recording mode information in association with each other, a selection procedure for selecting the group according to the operation, and a selection procedure selected by the selection unit when recording by the recording unit is executed. A setting procedure for setting the setting content indicated by each setting information forming the image capturing / recording mode information associated with a group to the image capturing unit or the signal processing unit can be executed. Further, as the management procedure, a process of forming the management information so that the image data recorded on a predetermined recording medium by the recording procedure is managed so as to belong to the group selected by the selecting unit. Was made executable.

According to the above arrangement, it is possible to manage a set of set values for various image pickup recording conditions such as exposure adjustment, white balance adjustment, image size and compression rate adjustment, etc., as image pickup recording mode information. In addition,

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. In the case where the recording device of the present embodiment is installed in a portable video camera in which a camera device part and a recording device part capable of recording and reproducing images (still images or moving images) and sound are integrated. Take as an example. In addition, the recording / reproducing device section mounted in the video camera of the present embodiment has a configuration for recording / reproducing data corresponding to a so-called mini disc (MD: Mini Disc) known as a type of magneto-optical disc. It is supposed to be taken. The description will be given in the following order. 1. Disk format 2. Internal structure of video camera 3. Configuration of media drive unit 4. 4. Example of disk structure corresponding to this embodiment Script 6. Correlation between folder and imaging recording mode information 7. Folder editing process 8. Shooting / image recording control processing operation 9. Modification

1. Disc Format The recording / reproducing device section mounted in the video camera of this example is compatible with a format called MD data, which records / reproduces data corresponding to a mini disc (magneto-optical disc). . As the MD data format, two types of formats called MD-DATA1 and MD-DATA2 have been developed. However, the video camera of this example has a higher density recording capability than MD-DATA1. It is said that recording / reproducing is performed in conformity with the above format. Therefore, first MD
The disk format of DATA2 will be described.

1 and 2 conceptually show an example of a track structure of a disc as MD-DATA2. 2 (a) and 2 (b) are a cross-sectional view and a plan view, respectively, showing, in an enlarged manner, the portion enclosed by the broken line A in FIG. As shown in these figures, two types of grooves (grooves), namely a wobbled groove WG provided with wobble (meandering) and a non-wobbled groove NWG not provided with wobble, are previously formed on the disc surface. It is formed. And these wobbled groove WG and non-wobbled groove NWG
Exist in a double spiral shape on the disk so that lands Ld are formed therebetween.

In the MD-DATA2 format, the land Ld is a recording track (track on which data is recorded).
However, since the wobbled groove WG and the non-wobbled groove NWG are formed as described above, the track Tr is also used as a recording track.
・ Two tracks of A, Tr, and B are independent,
It will be formed in a double spiral shape. The track Tr · A is a track in which the wobbled groove WG is located on the outer peripheral side of the disc and the non-wobbled groove NWG is located on the inner peripheral side of the disc.
On the other hand, the tracks Tr and B are tracks in which the wobbled groove WG is located on the inner circumference side of the disc and the non-wobbled groove NWG is located on the outer circumference side of the disc.
That is, it can be considered that the wobble is formed only on one side on the outer peripheral side of the disk with respect to the track Tr · A, and the wobble is formed on only one side on the inner peripheral side of the disk as the track Tr · B. . In this case, the track pitch is the distance between the centers of the adjacent tracks Tr.multidot.A and the tracks Tr.multidot.B, and the track pitch is 0.95 .mu.m as shown in FIG. 2B.

Here, the wobble formed in the groove as the wobbled groove WG is formed based on a signal in which the physical address on the disc is encoded by FM modulation + biphase modulation. Therefore, it is possible to extract the physical address on the disc by demodulating the reproduction information obtained from the wobbling given to the wobbled groove WG during recording and reproduction. Further, the address information as the wobbled groove WG is commonly effective for the tracks Tr.A and Tr.B. That is, the track Tr.A located on the inner side and the track Tr.B located on the outer side across the wobbled groove WG share the address information by the wobbling given to the wobbled groove WG. . Note that such an addressing method is also called an interlace addressing method. By adopting this interlace addressing method, for example, it is possible to reduce the track pitch while suppressing crosstalk between adjacent wobbles. For a method of recording an address by forming a wobble on the groove, see A.
Also called a DIP (Adress In Pregroove) method.

Further, as described above, the identification of which of the tracks Tr.A and Tr.B sharing the same address information is traced can be performed as follows. For example, in the state where the main beam traces the track (land Ld) by applying the 3-beam method, the remaining two side beams trace the grooves located on both sides of the track traced by the main beam. It is possible to do so.

As a specific example, FIG. 2B shows a state in which the main beam spot SPm traces the track Tr · A. In this case, of the two side beam spots SPs1 and SPs2, the inner side beam spot SPs1 traces the non-wobbled groove NWG and the outer side beam spot Ss.
Ps2 will trace the wobbled groove WG. On the other hand, although not shown, if the main beam spot SPm is tracing the track Tr · B, the side beam spot SPs1 traces the wobbled groove WG and the side beam spot SP
s2 will trace the non-wobbled groove NWG. In this way, the main beam spot SPm
When tracing track Tr / A and track T
In the case of tracing r · B, the wobbling groove WG and the non-wobbled groove NWG are inevitably exchanged as the groove to be traced by the side beam spots SPs1 and SPs2.

Side beam spots SPs1 and SPs2
As a detection signal obtained by the photodetector due to the reflection of, a different waveform is obtained depending on which one of the wobbled groove WG and the non-wobbled groove NWG is being traced. By determining which of the side beam spots SPs1 and SPs2 is tracing the wobbled groove WG (or the non-wobbled groove NWG), the main beam is track Tr.
It is possible to identify which of Tr and B is being traced.

FIG. 3 shows the main specifications of the MD-DATA2 format having the track structure as described above.
FIG. 6 is a diagram showing a comparison with the DATA1 format. First, the MD-DATA1 format has a track pitch of 1.6 μm and a pit length of 0.59 μm / bit.
Becomes Further, the laser wavelength λ is set to 780 nm and the aperture ratio NA of the optical head is set to 0.45. As a recording method, a groove recording method is adopted. That is, the groove is used as a track for recording and reproduction.
As an address method, a method is used in which a groove (track) is formed by a single spiral and then a wobbled groove in which wobbles are formed as address information on both sides of this groove is used.

As a recording data modulation method, EFM (8
-14 conversion) method is adopted. As an error correction method, ACIRC (Advanced Cross Interleave Reed-
Solomon Code) is adopted, and convolutional type is adopted for data interleaving. Therefore, the data redundancy is 46.3%.

In the MD-DATA1 format, CLV (Constant Linear V) is used as a disk drive system.
erocity) is adopted, and as the linear velocity of CLV,
It is set to 1.2 m / s. The standard data rate during recording and reproduction is 133 kB / s, and the recording capacity is 140 MB.

On the other hand, as the MD-DATA2 format that the video camera of this example can support, the track pitch is 0.95 μm and the pit length is 0.39 μm / b.
It is set to it and both are shorter than the MD-DATA1 format. In order to realize the above pit length, for example, the laser wavelength λ = 650 nm and the aperture ratio NA = 0.52 of the optical head are used to narrow the beam spot diameter at the focus position and widen the band as an optical system. .

As described with reference to FIGS. 1 and 2, the land recording method is adopted as the recording method, and the interlace addressing method is adopted as the address method. Further, as a recording data modulation method, the RLL (1, 7) method (RLL;
Run Length Limited) is adopted, the RS-PC method is used as the error correction method, and the block completion method is used for the data interleave. As a result of adopting each of the above methods, the data redundancy can be suppressed to 19.7%.

Even in the MD-DATA2 format, CLV is adopted as a disk drive system, but its linear velocity is 2.0 m / s, and the standard data rate at the time of recording / reproducing is 589 kB / s. It is said that As a recording capacity, 650 MB can be obtained, and when compared with the MD-DATA1 format, high-density recording of slightly more than 4 times is realized. For example, assuming that a moving image is recorded in the MD-DATA2 format, MPEG is used for moving image data.
When the compression coding by 2 is performed, it is possible to record a moving image of 15 to 17 minutes in time depending on the bit rate of the encoded data. In addition, assuming that only audio signal data is recorded, ATR is applied to audio data.
When compression processing by AC (Adaptive Transform Acoustic Coding) 2 is performed, recording can be performed for about 10 hours.

2. Internal Configuration of Video Camera FIG. 4 is a block diagram showing an internal configuration example of the video camera of this example. In the lens block 1 shown in this figure, for example, an optical system 11 that actually includes an imaging lens, a diaphragm, and the like is actually provided. The camera lens 201 shown in FIG. 6 is included in the optical system 11. Further, the lens block 1 includes a focus motor for causing the optical system 11 to perform an autofocus operation, and a zoom for moving the zoom lens based on an operation of a zoom key (not shown) provided outside the housing. The motor, the diaphragm adjustment motor for adjusting the diaphragm, etc.
It is provided as the motor unit 12.

The camera block 2 is mainly provided with a circuit section for converting the image light taken by the lens block 1 into a digital image signal. For the CCD (Charge Coupled Device) 21 of this camera block 2,
An optical image of the subject that has passed through the optical system 11 is provided. C
In the CD 21, an image pickup signal is generated by performing photoelectric conversion on the optical image, and the sample hold / AGC (A
Utomatic Gain Control) circuit 22. The sample hold / AGC circuit 22 performs gain adjustment on the image pickup signal output from the CCD 21 and performs waveform shaping by performing sample hold processing. The output of the sample hold / AGC circuit 2 is the video A / D
By being supplied to the converter 23, it is converted into digital image signal data.

The CCD 21, sample hold / AG
The signal processing timing in the C circuit 22 and the video A / D converter 23 is controlled by the timing signal generated by the timing generator 24. The timing generator 24 inputs a clock used for signal processing in a data processing / system control circuit 31 (inside the video signal processing circuit 3) described later, and generates a required timing signal based on this clock. To be done. As a result, the signal processing timing in the camera block 2 is synchronized with the processing timing in the video signal processing unit 3. Camera controller 2
The reference numeral 5 executes required control so that the functional circuit sections provided in the camera block 2 operate properly. Further, in the case of this example, based on various setting values supplied from the video controller 38 described later, autofocus, shutter speed adjustment, exposure adjustment, sensitivity adjustment, etc. are performed on the lens block 1 and / or the camera block 2. It also controls the operation. For example, in the case of auto focus control, the camera controller 25 controls the rotation angle of the focus motor based on focus control information obtained according to a predetermined auto focus control method. As a result, the image pickup lens is driven so as to be in the just focus state.

At the time of recording, the video signal processing unit 3 compresses the digital image signal supplied from the camera block 2 and the digital audio signal obtained by collecting the sound by the microphone 202, and outputs the compressed data. It is supplied to the media drive unit 4 in the subsequent stage as user recording data. Further, the image generated by the digital image signal and the character image supplied from the camera block 2 is supplied to the viewfinder drive unit 207 and displayed on the viewfinder 204. During reproduction, demodulation processing is performed on user reproduction data (read data from the disk 51) supplied from the media drive unit 4, that is, compressed image signal data and audio signal data, and these are reproduced image signals. , Output as a reproduced audio signal.

In this example, as a compression / decompression processing method of image signal data (image data), MPEG (Moving Picture Experts Group) 2 is adopted for moving images and JPEG (Joint Photographic) for still images.
Coding Experts Group) has been adopted. Also, the audio signal data compression / expansion processing method is ATR.
AC (Adaptive Transform Acoustic Coding) 2 shall be adopted. Further, in this example, for still images, for example, GIF (Graphics Interchange Fo
rmat), TIFF (Tagged Image File Format) format, and other files in formats other than JPEG.

The data processing / system control circuit 31 of the video signal processing unit 3 mainly controls the video signal processing unit 3 and the video signal processing unit 3 by controlling the compression / expansion process of image signal data and audio signal data. Executes the process to control the input / output of data passing through. In addition, the data processing / system control circuit 31
The control processing for the entire video signal processing unit 3 including
The video controller 38 is made to execute. The video controller 38 is configured to include, for example, a microcomputer and the like, and can communicate with the camera controller 25 of the camera block 2 and a driver controller 46 of the media drive unit 4 described later via, for example, a bus line (not shown). Has been done.

As a basic operation at the time of recording in the video signal processing unit 3, the image processing data supplied from the video A / D converter 23 of the camera block 2 is input to the data processing / system control circuit 31. The data processing / system control circuit 31 supplies the input image signal data to, for example, the motion detection circuit 35. The motion detection circuit 35 performs image processing such as motion compensation on the input image signal data while using the memory 36 as a work area, and then supplies the image signal data to the MPEG2 video signal processing circuit 33.

In the MPEG2 video signal processing circuit 33, for example, while using the memory 34 as a work area, the input image signal data is compressed according to the MPEG2 format, and a bit stream (MPEG2) of compressed data as a moving image is applied. Bitstream) is output. In addition, in the MPEG2 video signal processing circuit 33, for example, when image data as a still image is extracted from image signal data as a moving image and compression processing is performed on this, compressed image data as a still image according to the JPEG format. Is configured to generate. In addition, the MPEG2 signal processing circuit 33
In addition to the image data compression / expansion processing, the video controller 38 can perform image size conversion and image editing processing that gives a predetermined special effect to the original image data. ing. Further, the still image data may be compressed image data in a required format such as JPEG and GIF according to an instruction from the video controller 38. As the compressed image data in the MPEG2 format, I picture (Intra Pic
(ture) may be treated as image data of a still image. The image signal data (compressed image data) compressed and encoded by the MPEG2 video signal processing circuit 33 is written to the buffer memory 32 at a predetermined transfer rate and temporarily held, for example. In the MPEG2 format, as is well known, as a so-called coding bit rate (data rate), a constant speed (CBR;
Constant Bit Rate) and variable speed (VBR; Variable)
Both Bit Rate) are supported, and the video signal processing circuit 33 can handle both of them.

For example, in the case of performing image compression processing by VBR, the motion detection circuit 35 detects the motion of the image data within a range of several tens to several hundreds of frames in units of macro blocks, and determines that there is motion. For example, the detection result is transmitted to the MPEG2 video signal processing circuit 33 as motion vector information. MPEG2 video signal processing circuit 33
Then, in order to set the image data after compression encoding to a certain required data rate, while using the required information including the above motion vector information, the quantization coefficient for each macroblock is determined. To be done.

The audio compression encoder / decoder 37 includes
A / D converter 64 (display / image / sound input / output unit 6
For example, the sound collected by the microphone 202 is input as digital audio signal data via (inside). The audio compression encoder / decoder 37 performs compression processing on the audio signal data input according to the ATRAC2 format as described above. This compressed audio signal data is also written into the buffer memory 32 by the data processing / system control circuit 31 at a predetermined transfer rate and temporarily stored therein.

As described above, the compressed image data and the compressed audio signal data can be stored in the buffer memory 32. The buffer memory 32 mainly absorbs the speed difference between the data transfer rate between the camera block 2 or the display / image / audio input / output unit 6 and the buffer memory 32 and the data transfer rate between the buffer memory 32 and the media drive unit 4. It has a function for. Buffer memory 3
The compressed image data and the compressed audio signal data accumulated in 2 are sequentially read at a predetermined timing during recording and are transmitted to the MD-DATA2 encoder / decoder 41 of the media drive unit 4. However, for example, the operation of reading the data stored in the buffer memory 32 during reproduction and recording the read data from the media drive unit 4 to the disc 51 via the deck unit 5 is performed intermittently. I don't mind. The data writing / reading control with respect to the buffer memory 32 is executed by the data processing / system control circuit 31, for example.

The operation of the video signal processing unit 3 during reproduction is roughly as follows. At the time of reproduction, compressed image data and compressed audio signal data (user reproduction data) read from the disk 51 and decoded according to the MD-DATA2 format by the processing of the MD-DATA2 encoder / decoder 41 (in the media drive unit 4), Data processing / system control circuit 31
Will be transmitted to. In the data processing / system control circuit 31, for example, the input compressed image data and compressed audio signal data are temporarily stored in the buffer memory 32. Then, for example, the compressed image data and the compressed audio signal data are read from the buffer memory 32 at a required timing and a transfer rate so that the reproduction time axis is aligned, and the compressed image data is MPEG2.

In the display / image / sound input / output unit 6,
The image signal data input to the video D / A converter 61 is converted into an analog image signal here, and branched and input to the display controller 62 and the composite signal processing circuit 63. The display controller 62 drives the display unit 6A based on the input image signal. As a result, the reproduced image is displayed on the display unit 6A. Further, in the display section 6A, not only the display of the image obtained by reproducing from the disc 51, but naturally, the captured image obtained by photographing with the camera part including the lens block 1 and the camera block 2 is also displayed. It is possible to display and output in almost real time. In addition to the reproduced image and the captured image, the G
A UI (Graphical User Interface) is also displayed. Such GUI display is image signal data to be output from the data processing / system control circuit 31 to the video D / A converter 61 so that the required GUI is displayed at a predetermined position under the control of the video controller 38, for example. On the other hand, a process of synthesizing required image signal data may be executed.

A touch panel 6B is combined with the display section 6A to form a display panel 67. The touch panel 6B detects the position information of the pressing operation performed on the display unit 6A, and outputs this as operation information to the video controller 38.

The composite signal processing circuit 63 converts the analog image signal supplied from the video D / A converter 61 into a composite signal and outputs the composite signal to the video output terminal T1. For example, by connecting to an external monitor device or the like via the video output terminal T1, it becomes possible to display an image reproduced by the video camera on the external monitor device.

In the display / image / audio input / output unit 6, the audio signal data input from the audio compression encoder / decoder 37 to the D / A converter 65 is converted into an analog audio signal here, and the headphone / line terminal is used. T
It is output to 2. Further, the analog audio signal output from the D / A converter 65 is also branched and output to the speaker 205 via the amplifier 66, whereby the reproduced sound or the like is output from the speaker 205. Become.

In the media drive unit 4, the recording data is mainly encoded according to the MD-DATA2 format during recording so as to be suitable for disc recording and transmitted to the deck unit 5, and at the time of reproduction, from the disc 51 in the deck unit 5 during reproduction. Reproduced data is obtained by performing decoding processing on the read data and transmitted to the video signal processing unit 3.

When recording, the A2 encoder / decoder 41
Recorded data (compressed image data + compressed audio signal data) is input from the data processing / system control circuit 31, the record data is subjected to a predetermined encoding process in accordance with the MD-DATA2 format, and the encoded data is temporarily stored. It is stored in the buffer memory 42. Then, the data is transmitted to the deck unit 5 while being read at a required timing.

At the time of reproduction, the digital reproduction signal read from the disk 51 and inputted through the RF signal processing circuit 44 and the binarization circuit 43 is MD-DAT.
Decoding processing according to the A2 format is performed and the reproduced data is transmitted to the data processing / system control circuit 31 of the video signal processing unit 3. Even at this time, if necessary, the reproduction data is temporarily stored in the buffer memory 42, and the data read out from the buffer memory 42 is transmitted and output to the data processing / system control circuit 31 at a required timing. The writing / reading control for the buffer memory 42 is executed by the driver controller 46. It should be noted that, for example, during reproduction of the disk 51, even when the servo or the like is disengaged due to disturbance or the like and the signal cannot be read from the disk, the read data is accumulated in the buffer memory 42 within the period. If the reproduction operation for the disc is restored, it is possible to maintain the time-series continuity of the reproduction data.

The RF signal processing circuit 44 includes a disk 51.
By performing the required processing for the read signal from
For example, a servo control signal such as an RF signal as reproduction data, a focus error signal for servo control of the deck portion 5, a tracking error signal, or the like is generated. RF
The signal is binarized by the binarization circuit 43 as described above and input to the MD-DATA2 encoder / decoder 41 as digital signal data. In addition, the generated various servo control signals are supplied to the servo circuit 45. In the servo circuit 45, based on the input servo control signal,
The required servo control in the deck section 5 is executed.

In this example, MD-DATA1

The optical head 53 outputs a high level laser output for heating the recording track to the Curie temperature during recording, and a relatively low level laser output for detecting data from the reflected light by the magnetic Kerr effect during reproduction. . Therefore, although not shown in detail here, the optical head 53 is equipped with a laser diode as a laser output unit, an optical system including a polarization beam splitter, an objective lens, and the like, and a detector for detecting reflected light. There is. The objective lens provided in the optical head 53 is held by a biaxial mechanism, for example, so as to be displaceable in the radial direction of the disk and in the direction of approaching and separating from the disk.

Information detected by the data read operation of the optical head 53 with respect to the disk 51 (photocurrent obtained by detecting laser reflected light by a photodetector)
Is supplied to the RF amplifier 101 in the RF signal processing circuit 44. The RF amplifier 101 generates a reproduction RF signal as a reproduction signal from the input detection information and supplies it to the binarization circuit 43. The binarization circuit 43 binarizes the input reproduction RF signal to obtain a digital reproduction RF signal (binarized RF signal). This binarized RF signal is supplied to the MD-DATA2 encoder / decoder 41, and first, the AGC / clamp circuit 103.

The frequency of the clock CLK corresponds to the current disk rotation speed. Therefore, the CLV processor 11
In 1, the clock C is output from the equalizer / PLL circuit 104.
Error information is obtained by inputting LK and comparing with a reference value corresponding to a predetermined CLV speed (see FIG. 3), and this error information is used as a signal component for generating the spindle error signal SPE. The clock CLK includes, for example, the RLL (1,7) demodulation circuit 106,
It is used as a clock for processing in the required signal processing circuit system.

The Viterbi decoder 105 includes an equalizer / P
The binarized RF signal input from the LL circuit 104 is decoded according to the so-called Viterbi decoding method. As a result, the reproduced data as the RLL (1,7) code string can be obtained. This reproduction data is RLL (1,

7) The data stream is demodulated.

The data stream obtained by the demodulation processing in the RLL (1,7) demodulation circuit 106 is written to the buffer memory 42 via the data bus 114 and expanded on the buffer memory 42. The data stream expanded on the buffer memory 42 in this way is first subjected to error correction processing in error correction block units according to the RS-PC system by the ECC processing circuit 116, and further descrambled / E.
The DC decoding circuit 117 performs descramble processing and EDC decoding processing (error detection processing). The data processed so far is the reproduction data DA.
TAp. This reproduction data DATAp has a transfer rate according to the transfer clock generated by the transfer clock generating circuit 121, and is, for example, from the descramble / EDC decoding circuit 117 to the data processing / data processing of the video signal processing unit 3.
It will be transmitted to the system control circuit 31.

The transfer clock generation circuit 121 is, for example,
When performing data transmission between the media drive unit 4 and the video signal processing unit 3 based on a crystal clock, or data transmission between the functional circuit units in the media drive unit 4, transfer of an appropriate frequency is appropriately performed. It is a part for generating a clock (data transfer rate). Also,
A clock having a required frequency to be supplied to each functional circuit unit of the media drive unit 4 and the video signal processing unit 3 is generated according to the operation state of the video camera.

The detection information (photocurrent) read from the disk 51 by the optical head 53 is the matrix amplifier 1
It is also supplied to 07. In the matrix amplifier 107, the tracking error signal TE, the focus error signal FE, and the groove information (absolute address information recorded as the wobbled groove WG on the disc 51) GFM are obtained by performing necessary arithmetic processing on the input detection information. Etc. are extracted and supplied to the servo circuit 45. That is, the extracted tracking error signal TE and focus error signal FE are supplied to the servo processor 112, and the groove information GFM is supplied to the ADIP band pass filter 108.
Is supplied to.

The groove information GFM band-limited by the ADIP bandpass filter 108 is the A / B track detection circuit 109, the ADIP decoder 110, and the CLV.
It is supplied to the processor 111. In the A / B track detection circuit 109, based on the method described in FIG. 2B, the currently traced track is track TR.
It is determined which of A, TR and B is set, and the track determination information is used as the driver controller 46.
Output to. Further, the ADIP decoder 110 decodes the input groove information GFM to extract an ADIP signal which is absolute address information on the disc, and outputs it to the driver controller 46. The driver controller 46 executes required control processing based on the track discrimination information and the ADIP signal.

The clock CLK from the equalizer / PLL circuit 104 and the groove information GFM via the ADIP bandpass filter 108 are input to the CLV processor 111. The CLV processor 111 generates a spindle error signal SPE for CLV servo control based on an error signal obtained by integrating a phase error between the groove information GFM and the clock CLK and outputs the spindle error signal SPE to the servo processor 112. The required operation to be executed by the CLV processor 111 is controlled by the driver controller 46.

The servo processor 112 receives various servo control signals based on the tracking error signal TE, the focus error signal FE, the spindle error signal SPE, the track jump command from the driver controller 46, the access command, etc. which are input as described above. (Tracking control signal, focus control signal, sled control signal, spindle control signal, etc.) are generated and output to the servo driver 113. In the servo driver 113,

Scramble / ED from system control circuit 31
Recording data DATAr for the C encode circuit 115
Will be input. This user record data DAT

DC encoding processing (addition processing of error detection code by a predetermined method) is performed. After this processing, for example, the ECC processing circuit 116 adds an error correction code based on the RS-PC method to the recording data DATAr expanded in the buffer memory 42. The recording data DATAr that has been subjected to the processing up to this point is read from the buffer memory 42 and passed through the data bus 114 to the RL.
It is supplied to the L (1,7) modulation circuit 118.

In the RLL (1,7) modulation circuit 118, RLL (1,7) is applied to the input recording data DATAr.
7) A modulation process is performed, and the recording data as the RLL (1,7) code string is output to the magnetic head drive circuit 119.

By the way, in the MD-DATA2 format, a so-called laser strobe magnetic field modulation method is adopted as a recording method for the disc. The laser strobe magnetic field modulation method refers to a recording method in which a magnetic field modulated by recording data is applied to the recording surface of a disk and a laser beam to be applied to the disk emits a pulse in synchronization with the recording data. In such a laser strobe magnetic field modulation method, the formation process of the pit edge recorded on the disc is determined by the laser pulse irradiation timing without depending on the transient characteristics such as the reversal speed of the magnetic field. Therefore, as compared with, for example, a simple magnetic field modulation method (a method in which a disk is constantly irradiated with a laser beam and a magnetic field modulated by recording data is applied to a disk recording surface), a laser strobe magnetic field modulation method is used. In, it is possible to easily make the jitter of the recording pit extremely small. That is, the laser strobe magnetic field modulation method is a recording method advantageous for high density recording.

The magnetic head drive circuit 119 of the media drive unit 4 operates so that the magnetic field modulated by the input recording data is applied from the magnetic head 54 to the disk 51. Further, the RLL (1,7) modulation circuit 118 outputs a clock synchronized with the recording data to the laser driver 120. The laser driver 120 causes the optical head 5 to irradiate the disk with a laser pulse synchronized with recording data generated as a magnetic field by the magnetic head 54 based on the input clock.
3 laser diode is driven. At this time, the laser pulse emitted from the laser diode is based on the required laser power suitable for recording. In this way, the recording operation as the laser strobe magnetic field modulation method is enabled by the media drive unit 4 of this example.

4. Example of Disk Structure Corresponding to this Embodiment Next, an example of the data structure of the disk 51 corresponding to this embodiment will be described. First, a data unit called a sector or a cluster will be described as a format of MD-DATA2. A sector is the minimum unit of physical data read from the disk, and each sector has P
SA (Physical Sector Address) is assigned. A cluster is a minimum unit of physical data writing to the disk, and is formed by a set of 16 consecutive sectors of PSA from 0h to Fh. A PCA (Physical Cluster Address) is assigned to each cluster. Then, the sector in the lead-in area (pre-mastered area) described later can be uniquely specified by the PCA. Further, among the clusters in the recordable area, the clusters having the same PCA are track T
There will be one each for r · A and Tr · B.

Next, a file management system in the MD-DATA2 format will be described.
In the format of MD-DATA2, TMS (Track Management System) is defined as a file management system. This TMS is the most basic rule for allocating a recording area of a disc according to the MD-DATA2 format, and for example, about 5,500 pieces of information can be hierarchically classified and recorded. ing.

In the TMS, tracks and folders are defined to realize a hierarchical management structure. A track is a minimum unit of a group of data that is directly managed by TMS, and is basically synonymous with a file. Each track is represented by a Track Descriptor. The folder has a structure for grouping and managing tracks. Each track and folder belong to a certain folder (Parent Folder), and finally Root Fol.
Construct a tree structure with der as the root. Each folder is represented by a Folder Descriptor. An ID is given to each track / folder.

FIG. 6 shows an example of a hierarchical structure under TMS. In TMS, all tracks and folders are linked by two kinds of links in order to realize a hierarchical folder structure and to define a search order of tracks and folders. One is a link pointing to a parent folder of a track / folder, which makes it possible to recognize which folder the track / folder belongs to. Also,
The other is a link that sequentially connects the tracks / folders that belong to the folder, starting with the Parent Folder. This makes it possible to define the search order of tracks / folders within that folder, and to realize high-speed search. And all tracks / folders on the disc are Root Folder
Since it will be placed in the tree structure with root as the root, the folder in the route starting from Root Folder,
The permutation of its own ID allows it to be uniquely identified on the disc.

For example, in the example shown in FIG.
It is assumed that the ot Folder has an ID of 0000h (h indicates hexadecimal notation). And as its child, there are 3 of Folder 0101h, Track 0088h, and Folder 0201h.
It is supposed to be. And these 3 Folder / Track
As shown in the figure, Folder 0101h → Track 0088h → F
The order is stipulated so that older is 0201h.
In addition, in the Folder 0101h, Track 0077h, Track 0088h,
3 tracks of Track 0070h belong, and these 3
For track playback order, see Track 0077h → Track 008.
8h, Track → 0070h. Also,
Folder 0201h, which is a child of Root Folder, has additional Folder
r 0201h and Track 0120h belong, and the order is Folder
0201h → Track 0120h.

Here, Track 0088h (De
(scriptor Number = 39) and Track 0 belonging to Folder 0101h
088h (Descriptor Number = 26) has the same ID, but these are different Descriptor Numbers.
As can be seen from the fact that they are assigned, they are considered to be independent entities. This is the same for folders, and in the figure, F, which is a child of Root Folder
older 0210h (Descriptor Number = 77) and its children
Folder 0210h (Descriptor Number = 4) corresponds to this.

FIG. 7 conceptually shows an example of a data management mode of the disk 51 which is considered to correspond to this embodiment. The physical format of the disk 51 shown in this figure is as described above with reference to FIGS. In the disk 51, for example, PTOC and RTOC are set as management information. PTOC is
Required management information is recorded according to the pit form. This P
The contents of TOC cannot be rewritten. RTOC
For example, basic information necessary for managing the data recorded on the disc is recorded. It should be noted that the contents of the RTOC are sequentially rewritten, for example, in accordance with the result of data recording on the disk so far and the result of editing processing such as deletion of tracks (files) and folders.

User data is managed as a volume folder placed in one root folder. Volume in this embodiment
Is defined as a complete set of user data, and is defined as having only one volume on one disk. The data contained in this volume will be stored as folders and tracks below the volume folder except those managed by the PTOC and RTOC.

A volume index track (VIT) of a predetermined size (for example, 12 clusters) is placed in the volume folder. This volume index track is, for example, the PT
When OC and RTOC are the main management information, they are defined as an area in which the sub management information is recorded, so to speak, and are track (file), folder, and auxiliary data (Auxiliary).
Data), a property, a title, and a table in which information for managing packet data forming a track is recorded.

As a track managed in the volume folder, a thumbnail track (Thumbnail Pictu
re Track) can be arranged as an option.
In the present embodiment, it is possible to have one still image with a predetermined resolution as a thumbnail image in association with each file recorded on the disc. The thumbnail image is treated as a representative image for visually recognizing the file. The thumbnail track is recorded together with the index information indicating the correspondence with the file (track) recorded on the disc and the storage position of the thumbnail image. The data length of the thumbnail track can be arbitrarily expanded according to the number of thumbnail images stored.

The image / audio data recorded by the user by shooting or the like is managed in file units, and is placed in the volume folder as a track under the volume folder or in a folder placed below the volume folder. Will be placed. FIG. 7 shows a state in which one certain file is expressed as one track and this track is stored in one certain folder. As described above, the folder is a structure for collectively managing the tracks or folders in one group. Therefore, in the structure below the volume folder, an arbitrary number of tracks or folders can be stored within the range defined by the maximum number of items that can be stored in the volume folder and the maximum number of layers in the folder hierarchical structure.

Further, in the volume folder, auxiliary data tracks in which auxiliary data (Auxiliary Data) are stored
(Auxiliary Data Track) is placed. The information to be stored in the auxiliary data track is arbitrary, for example, depending on the application actually applied. In the present embodiment, script information serving as reproduction control information is stored.

By the way, the PTO which is the management information described above.
The information stored in the C, RTO C, and further the volume index track (these information items are collectively referred to as “management information” in the present embodiment) is read out when the disc is loaded, for example. For example,
It is held in a predetermined area of the buffer memory 42 (or the buffer memory 32) of the media drive unit 4. When recording or editing data, the management information retained in the buffer memory is rewritten according to the recording result or the editing result, and then, the buffer memory is stored at a predetermined opportunity and timing. The management information of the disk 51 is rewritten (updated) based on the content of the management information held (however, P
The TOC will not be updated).

Further, according to the above description, it is understood that the files recorded on the disc can be managed as being stored in the folder.
Moreover, in the present embodiment, when storing the captured image data file in the folder, as shown in FIG. 7, the captured image recording mode information is associated with each folder and It is managed. Although details of the image pickup recording mode information will be described later, the image pickup recording mode information includes setting information about various setting items for the lens block 1, the camera block 2, and the video signal processing unit 3 in order to obtain a required image pickup recording condition.

In the present specification, the disk 51
Among the management information for managing the files recorded in the above, the management information portion having the function of managing the files in units of folders as described above will be particularly referred to as “folder management information”. With this folder management information according to the present embodiment, as described later,
The image capturing / recording condition based on the image capturing / recording mode information is set according to the folder selecting operation, and the file of the image captured according to the image capturing / recording condition is recorded so as to be stored in the folder selected by the folder selecting operation. It is possible.

FIG. 8 shows the data management form shown in FIG. 7 in association with the physical structure of the disk 51. The lead-in area shown in this figure is a pit area in the innermost circumference of the disc, and PTOC information is recorded therein.

A recordable area is formed on the outer circumference of the lead-in area through the transition area. This recordable area is a magneto-optical recording area in which magneto-optical recording and reproduction are possible. In the recordable area, as described above with reference to FIGS. 1 and 2, two tracks of the track Tr.multidot.A and the track Tr.multidot.B are formed in a double spiral shape.

At the innermost circumference of the recordable area,
An RTOC area is provided for both the tracks Tr.A and Tr.B. Then, in the RTOC area of the track Tr · A, the information of the RTOC having the size of 4 clusters is repeatedly recorded 3 times. And, following this, 12
A cluster-sized volume index track is placed. Then, following the volume index track, a thumbnail track can be arranged as an option. As a thumbnail track in this RTOC area, at least the first cluster is defined. Then, for example, when the number of thumbnail image data increases as the number of files increases and exceeds the capacity of the thumbnail track in the RTO C area, additional recording can be performed in a recordable data area described later. . The thumbnail track on the recordable data area at this time is managed by the volume index track (or RTOC).

Further, following the thumbnail track of the RTOC area, an area for recording the script, the image data, and the imaging recording mode information, which are auxiliary data, can be set as an option. Also, with regard to these scripts and image data, when they exceed the recordable capacity in the RTOC area, they are additionally recorded in the recordable data area in a form managed by the volume index track (or RTOC). You can go.

A recordable data area is provided from the address position indicated by the start address W of the recordable data area. AV data, that is, track (file) data is recorded in the recordable data area. Also, the thumbnail image data and the auxiliary data described above can be recorded.

When this recordable data area ends, a lead-out area is formed from the address position indicated by the lead-out area start address L to the outermost circumference.

Although the above description relates to the track Tr.multidot.A, as for the track Tr.multidot.B, the area setting conforms to that of the track Tr.multidot.A, as can be seen from FIG. However, the RTOC area is undefined at this stage. That is, the RTOC area is the track Tr · A.
Only about to be used substantially.

The examples of the disk structure shown in FIGS. 7 and 8 are merely examples, and the physical positional relationship of each area on the disk may be changed according to the actual use conditions. The structure in which the data is stored is subject to change.

5. Script In this embodiment, a file recorded by the video camera (mainly an image data file) can be subjected to editing processing such as giving a required special effect. In performing the editing as described above, in the present embodiment, a script as reproduction control information capable of giving a desired reproduction output mode for a recorded file is prepared. In the video camera, for example, the video controller 38 By interpreting the script, a reproduction output mode (for example, reproduction order) according to the editing result is obtained. Further, in the editing stage, the editing process is executed by updating the contents of the script. The "script" here means a procedure writing structure described in a predetermined programming language in order to reproduce and output moving image data, still image data, voice data, and document data at the same timing. To be taken.

Therefore, first, a script used as reproduction control information in the present embodiment will be briefly described.

In this embodiment, the script is SMIL (Synchronized Multimedia Integration Language).
ge) is adopted. SMIL is a language standardized by W3C (Internet standardization organization) in order to realize, for example, TV program broadcasting and presentation on the Internet, and XML (H
Based on the grammar of TML superset), it is intended to realize a presentation in time series.

First, the scheduling is performed by <seq>, <
It is represented by two tags of par>. <Seq>
Means sequential, that is, serial, and the information enclosed by this tag is reproduced in chronological order. <
par> means parallel, that is, parallel,
The information enclosed by this tag will be reproduced in synchronization.

Here, for example, in a file recorded on a disc, video1, video
2, regarding a file of image data represented as video3, video1 → video2 → video3
<Seq><video src = "video1"><video src = "video2"><video src = "video3"></seq> or <seq><play video1 The description is performed as follows: <play video2><playvideo3></seq>.

In addition, the file video1 → video

For audio1, which is a file of audio data
<Seq><par><video src = "video1"><audio src = "audio1"></par><video src = ”video2”><video src = ”video” The description is performed as in “></seq>”.

A description is also provided for specifying a file to be reproduced in synchronization with a certain file, such as how many seconds after the certain file is reproduced, the reproduction is started. For example, when a caption (for example, an image as text information) is displayed 5 seconds after the video file of video1 is displayed (reproduced), <par><video src = “video1”><image src = "Scratch1" begi
The description is performed as n = “5s”></par>.

For example, if an instruction is made to display the file picture1 as a still picture file for 5 seconds, <image src = “picture1” dur
= "5s">.

Also, so-called frame mute, "range" is used when a part of a certain moving image file is reproduced by being extracted. For example, as a time code, SMPTE (Society of Motion Pictu
<video src = “video1” range as if the standard of “re and Television” is adopted.

It can be described as follows.

Further, "repeat" is used to repeat a specified file. For example vi
If you want to repeat the file of "deo1" 10 times, <video src = "video1" repeat
It is described as at = "10">.

In the present embodiment, such a script called SMIL is used so that display control for giving a desired display form as thumbnail display can be executed. Therefore, for example, in the video camera system of the present embodiment, this S
Interpretation corresponding to MIL and script description (generation)
A subset of XML will be prepared so that This may be stored in advance in the ROM or the like in the video controller 38 as a program to be executed by the video controller 38, or may be recorded in the application layer of the disc so that it can be read.

In the present embodiment, such a script is generated or updated by the video controller 38, for example, at the editing stage (or at the stage of recording operation), for example, a predetermined script in the buffer memory 32. It is supposed to be held in the area. Then, the script thus held in the buffer memory 32 is recorded on the disk at a predetermined opportunity or timing. The data of this script is Auxiliary Data Track described in FIGS. 7 and 8.
However, it will be stored as a script file. By recording the script on the disc in this way, the script recorded on this disc will be read when the disc is newly loaded next time.
For example, by holding the buffer memory 32 and referring to the buffer memory 32, it is possible to perform edit reproduction and the like according to a reproduction order obtained by previous edit.

6. Correlation between Folder and Image-Recording Mode Information By the way, in the video camera of the present embodiment, by setting various setting items during image-recording, the image-recording condition according to the user's preference can be obtained. Is configured as follows. In the present embodiment, as the setting items for obtaining the imaging recording condition as described above,
In FIG. 10, which will be described later, it is shown within a broken line. That is, “sensitivity”, “exposure”, “spot metering,“ focus ”,“ white balance (WB) ”,“ shutter speed ”,“ image size ”,“ compression ratio ”,“ color setting ”,“ blur setting ” By setting the item (1), the image capturing / recording condition according to the user's preference can be obtained.

Among these setting items, for example, "sensitivity", "spot metering", "white balance (W
B) ”,“ shutter speed ”, and other setting items, the camera block 2 sets the signal processing function corresponding to each item. “Focus” is a setting for controlling the focusing mechanism in the lens block 1. “Exposure” is a setting item that controls the state of the diaphragm in the lens block 1 and controls the signal processing function for the shutter speed in the camera block 2. Further, “image size”, “compression ratio”, “color setting”, “blurring setting”, etc. are settings for controlling the signal processing function in the MPEG2 video signal processing circuit 33.

By the way, the video camera as described with reference to FIGS. 4 and 5 normally records the photographed image data on the disc 51 in the photographing order. However, in recent years, the capacity of storage media has been increasing, and especially still image data that can be recorded and saved as hundreds of files has become widespread.
In such a method of recording images in the order of shooting, it becomes difficult to find a desired captured image. With regard to this problem, it is possible that the user manually manages the image data thus captured in a folder, but the work of moving each captured image data file to a folder is cumbersome and rational. Not a thing.

Therefore, in this embodiment, first, regarding each setting item for setting the above-mentioned image pickup recording condition,
A set of set values arbitrarily set by the user can be registered as one “imaging recording mode information”. And
A plurality of such “imaging recording mode information” can be registered. Specifically, for example, if you want to shoot a fast-moving player such as watching sports, set a high shutter speed for each setting item,
If the sensitivity is set to high sensitivity and the focus is set to full-time auto focus, it is possible to create imaging record mode information suitable for shooting a dynamic subject. Further, if it is used for the purpose of displaying captured image data on a mobile phone, for example, the image size is set to a size suitable for display on the mobile phone. In this way, a set of setting values in which various setting items are set according to the conditions at the time of shooting and the purpose of use of the image can be set as one “imaging and recording mode information”. If the user performs an operation for selecting "imaging and recording mode information" before photographing, the setting for a plurality of setting items in this imaging and recording mode is automatically performed.

Further, in the present embodiment, the above-mentioned image pickup recording mode information is associated with each folder and managed by the folder management information. In addition, the selection of the "imaging recording mode information" at the time of shooting described above is performed by an operation of selecting a folder. That is, by selecting a folder, the “imaging recording mode information” associated with the folder is selected, and the imaging recording condition is set by this “imaging recording mode information”. Further, the image data photographed in the state where the image recording condition is set as described above is configured to be stored in the folder selected by the previous selection operation. By doing so, first, by the operation of one action of selecting a folder, the setting of a plurality of setting items for obtaining the imaging recording condition desired by the user is automatically performed. Further, since the image data to be recorded is stored in the selected folder, the folders can be automatically classified according to the imaging recording conditions set when the image data was recorded.

7. Folder Editing Process By the way, as a folder associated with the above-mentioned image capturing / recording mode information, for example, a plurality of predetermined folders prepared as factory presets may be fixedly used. However, as long as the imaging record mode information should be set according to the user's preference, the folder associated with the imaging record mode information is newly created by the user or the setting contents of the folder already created ( It is preferable to provide a folder editing function such as changing the setting values of various setting items of the imaging recording mode information. Therefore, in the present embodiment, folder editing can be performed as described below.

FIG. 9 shows an example of the procedure of the folder editing operation by the user. First, when the user wants to edit a folder, the mode is changed to the edit mode by, for example, operating the operation unit 7 or the GUI displayed on the display unit 6A. Then, when shifting to the edit mode, a menu list as shown in FIG. 9A is displayed on the display section 6A.

Of the menus displayed here, the "basic folder" edit menu is a menu selected when making changes to the basic folder. The basic folder is a folder in which various set values of the set basic shooting mode are associated. Further, the “customized folder” edit menu is a menu selected when making changes to the already created customized folder. The customized folder is a folder that is created by the user's operation for creating a new folder and is associated with the imaging recording mode information according to various setting values arbitrarily set by the user. If the user wants to change the settings for these folders,
It suffices to operate the GUI of these menus. Also,
The “add folder” menu is a menu for creating a folder with new various setting values. The “delete folder” menu is a menu for deleting the folder currently managed by the folder management information.

Here, for example, the user is a "basic folder".
When it is desired to change the various setting values set in step 1, the cursor is operated as shown in the drawing so as to be aligned with the GUI of the "basic folder" edit menu. Then, by operating the "OK" button (not shown), this "basic folder" can be designated as the editing target.

When the folder is designated in this way, FIG.
A list of menus of setting items is displayed as shown in (b). Here, as the setting item menu, "sensitivity", "exposure", "spot metering", "focus", "white balance (WB)", "shutter speed", "image size", and "compression rate" are displayed as shown in the figure. , “Color setting”, and “Blur setting” are displayed. A specific example of what the setting values of these setting items are will be described later.

The user can select a desired item from each of the menus. For example, when a “sensitivity” selection operation is performed, a setting value selection menu as shown in FIG. 9C is displayed. As shown in the figure, since "sensitivity" is selected in this case, the set values of sensitivity are "auto", "ISO100", "ISO200", "ISO".
Each of "400" is displayed. Then, when the user wants to change the setting to, for example, "ISO100" from the setting of "auto" as the basic setting, the cursor is moved to "ISO10" as shown in the figure.
This value can be selected and determined in accordance with the display of "0".

In the video camera of this example, such menus are displayed in a hierarchy as shown in FIG.
That is, in FIG. 9, when the "edit" operation is performed and the mode is changed to the edit mode, the GUI of the "basic folder", each "customized folder", "add folder", and "delete folder" menu is displayed on the display unit 6A. Is displayed. This is shown in FIG. 9 (a).

Then, in the next hierarchy when the basic folder is selected, as shown in the figure, setting items such as “sensitivity”, “exposure”, “spot metering”, etc. are displayed, and further these items are selected. In the next layer, the setting values as shown in the figure are displayed according to the selected setting item. In the present embodiment, such a hierarchy of setting items and a hierarchy of setting values related to the setting items will be collectively referred to as a “setting menu”. Also,
The setting menu of the "basic folder" will be particularly called "basic setting menu".

Here, as the setting items exemplified in this figure, for example, "sensitivity" can be set to "automatic" or "ISO100" to "ISO400", which can be obtained in the case of film. It is possible to obtain a sensitivity corresponding to the sensitivity of. As "exposure", "automatic", "aperture priority", and "shutter speed priority" can be set. Further, "on / off" can be set as "spot metering", and "automatic", "full time", and "manual" can be set as "focus". Furthermore, "white balance (WB)" can be set to "clear weather", "cloudy weather", or the like, and it is possible to shoot with a value suitable for each selected shooting condition. In addition, "shutter speed" is "1 / 1000s", "1 / 5s"
"00s" and "1 / 100s" can be set.

As the "image size" and the "compression rate", for example, a size of "1800 x 1350", "high quality" or "low quality" can be set. As described above, since the “compression ratio” and the “image size” can be adjusted, the user can easily record the captured image data in a format corresponding to the purpose of web transmission, for example. Further, as the "color setting", the expression of the image data in the "normal" color (for example, 256 gradations),
Expressions in “sepia” and “monochrome” are possible.
Further, the "blurring setting" is a setting item for expressing the image data with a feeling that the focus is blurred, and can be set to ON / OFF.

Next, in FIG. 10, the "setting menu" for the customized folder is displayed as the next hierarchy when each "customized folder" edit menu is selected. The setting menu in this case is as shown in FIG. 11, for example. First, the difference between the "setting menu" and the "basic setting menu" for this customized folder is that there is a new option "use basic setting" in the hierarchy of setting values for each setting item as shown in the figure. It is a point to be added. Then, the user uses this "use basic settings"
When is selected, the setting value of this item is set to the same value as the value currently set in the basic setting. This makes it possible to easily copy the setting contents of the basic setting to the customized folder and set them. As shown in the figure, the list of “setting menu” for this customized folder may be the same as the list of “basic setting menu”, or in addition to this, new setting items may be added, or It can be omitted.

Then, in FIG. 10, when the "add folder" menu is selected in the first hierarchy in which the "edit" operation by the user is performed, "new creation" or "copy" is set as the next hierarchy. A menu for selecting either will be displayed. This "New" menu is a menu that should be selected when setting the setting values for each setting item one by one from the beginning, and the "Copy" menu is based on the folders that have already been set. This is the menu that should be selected when creating a simple folder.

When the user operates the "new creation" menu, the "setting menu" described above is displayed as shown in the figure. Then, by displaying this setting menu, the user can change / determine the setting value of each setting item in the same manner as described above.

When the "copy" menu is selected, all currently stored "customized folders" are displayed as the copy targets, as shown in the figure. Then, in the next layer in which any one of these customized folders is selected, a “setting menu” in which the setting values associated with the selected customized folder are copied is displayed. As a result, the user can create a new folder by selecting the item and changing the set value only for the item whose setting is to be changed in the setting contents of the customized folder selected in the previous hierarchy. In other words, in this case, the user only needs to change the setting values of the setting items that he / she wants to change, and saves the trouble of setting the other settings.

Next, when the "Delete folder" menu is selected in the first hierarchy in which the "Edit" operation by the user is performed, all the "customized folders" saved in the next hierarchy are selected. Display the list. Then, the user can delete the selected folder by designating a specific folder from this list and performing a deletion determination operation.

As described above, the video camera of this example displays the menu screen as described above according to the selection operation by the user. By operating the menu screen, the user can perform various editing operations regarding the folder.

In the video camera of this example, the editing operation according to the folder editing operation by the user is realized by the processing operation of the video controller 38. Less than,
The processing operation of the video controller 38 according to such a folder editing operation by the user will be described with reference to the flowchart of FIG.

In FIG. 12, the disk 51 is loaded in the deck portion 5, and the video controller 38
It is premised that at least the folder management information recorded in the RTO C area of the disc 51 and the imaging recording mode information associated with each folder managed by the disc 51 can be read.

First, in FIG. 12, step S101.
Determines whether the user has performed an operation for shifting to the edit mode. If there is an operation for editing, the process proceeds to step S102 to determine which edit menu the user has selected. That is, in this step S102, first, in FIG.
The menu list shown in (1) is displayed on the display unit 6A to prompt the user to select a menu, and the processing for determining the menu operated by the user is executed.

In step S102, if the "basic folder" menu is selected by the user's selection operation, step S103 follows. If the "customized folder" menu is selected, step S107 follows.
If the "add folder" menu is selected, the process proceeds to step S111, and if the "delete folder" menu is selected, the process proceeds to step S120.

First, in step S103 when the "basic folder" menu is selected, the "basic setting menu" described in FIG. 10 is created and displayed on the display unit 6A. Then, in the following step S104,
The user is made to select the setting item to be changed and change the setting value of the selected item. That is, at this time, the user uses the procedure as described above with reference to FIGS.
The setting item to be changed is selected, and the setting value of the selected item is changed.

When the user performs the item selection / setting value change operation in this manner in step S104, it is monitored in step S105 whether or not the user has made a determination operation. Then, if there is a decision operation in this step S105, the step S105
Proceed to 106.

In step S106, the disk 5
In step 1, the process of rewriting the set value of the imaging record mode information stored in association with the basic folder by the folder management information to a value based on the operation of selecting an item and changing the set value in step S104 is executed. Then, when this processing operation is executed, as shown in the figure, the editing processing operation of the basic folder ends, but in reality, the processing operation proceeds to step S102 until the editing mode ending operation is performed. , It will be monitored whether there is a menu selection operation. Note that this FIG.
In the flowchart of the above, "end of processing operation" means
This means the end of the series of processing operations of the selected edit menu, and as described above, it is assumed that the process actually proceeds to step S102 until the edit mode end operation is performed.

If the "customize folder" menu is selected in the previous step 102, the process proceeds to step S107. In this step S107, in order to change the item selection / setting value for the imaging / recording mode information of the selected customization folder, first, as the imaging / recording mode information associated with the selected customization folder. A set value is recognized and a "setting menu" is created based on this recognition.
Then, this is displayed on the display unit 6A, and the subsequent step S
Proceed to 108. In step S108, as in step S104 described above, the user is caused to select an item and change the setting value, and in subsequent step S109, it is monitored whether or not the user has made a determination operation.

In step S109, if there is a determination operation, the process proceeds to step S110, and the set value of the imaging recording mode information stored in association with the selected customization folder is set by the user in step S108. Rewrite the value based on the change operation of the set value. When this processing is executed, the processing operation is ended as shown in the figure.

Next, in step 102, if there is a selection operation of the "add folder" menu, the process proceeds to step S111. In this step S111,
As described above, the GUIs of "new creation" and "copy" are displayed on the display unit 6A, and the user is prompted to perform an operation to select which of these. Then, if "New" is selected, the process proceeds to step S112.

In step S112, a "basic setting menu" is created and displayed on display unit 6A. In this case, the "basic setting menu" is different from the one created in the previous step S103, and the one in which the setting value is not set in each setting item is created. And in this case, the following step S
In 113, the user is made to set the setting value of each item, and in the subsequent step S114, it is monitored whether or not there is a determination operation by the user. If there is a determination operation, the process proceeds to step S115.

In step S115, step S113
In, a new folder associated with the imaging record mode information set by the user's operation is created. That is, a process of recording the setting value of each setting item set by the user on the disk 51 as the imaging record mode information and updating the folder management information so that a new folder associated with the imaging record mode information is created. Is what you do. As a result, when the folder is selected by the user thereafter, each set value as the imaging record mode information is set in each required part as described later. When the folder creation processing in step S115 is executed, the processing operation ends.

In the previous step S111,
When "copy" is selected, the process proceeds to step S116. In step S116,
When creating a new folder, the GUI of each "customized folder" is displayed on the display unit 6A in order to select the folder to be the copy source. Then, among these, each setting value as the imaging recording mode information associated with the folder for which the selection operation has been performed is recognized, and a “setting menu” in which these setting values are copied is created. Further, the "setting menu" created in this way is displayed on the display unit 6A.

In the following step S117, the user is made to select the item to be changed / the setting value of the selected item is changed, and in the following step S118, it is monitored whether or not there is a determination operation by the user. Then, if there is a determination operation, the process proceeds to step S119.

In step S119, step S
Various setting values determined by the user in 117
Recording is performed on the disc 51 as the imaging record mode information, and processing for updating the folder management information is executed so that a new folder associated with the imaging record mode information is created. When this processing is executed, the processing operation ends.

Then, if there is an operation of selecting the "delete folder" menu in the previous step S102, the process proceeds to step S120. In step S120, in order to allow the user to select a folder to be deleted, a process of displaying on the display unit 6A a list showing all customized folders managed on the disk 51 by the folder management information is executed. . Then, as shown in the figure, in step S121, the user is made to perform a designation (selection) operation of a folder to be deleted, and in step S122, it is monitored whether or not there is a determination operation by the user. If the user makes a determination operation, the process proceeds to step S123.

In step S123, step S
In step 121, the folder management information is rewritten so that the folder determined by the user's selection operation is deleted. Then, when this processing is executed, the processing operation ends.

Here, as described above, when a new folder is added in step S115 and step S119, the user who has been able to input an arbitrary folder name in this folder has taken a picture. This is preferable because the convenience in managing the image data is improved. Also, when the editing process is performed on the existing folder in step S110, similarly, it is preferable that the user can input an arbitrary folder name to the edited folder.
Therefore, as for the video camera of the present example, although not described by way of illustration, it is assumed that the following folder name input / change processing can be executed in addition to the folder editing processing operation of FIG. .

In this case, as the processing of FIG. 12, after each of the processing of steps S110, S115, and S119, processing for allowing the user to input / change the folder name is provided, and the folder input in this processing is further provided. It suffices to provide processing for updating the folder management information so that the name and the folder are associated with each other. By doing so, when the folder list screen is displayed as a GUI on the display unit 6A thereafter, the folder name input together with this folder is displayed. In addition,
It is also possible that the above-mentioned editing process can be executed for the basic folder.

8. Shooting / Image Recording Control Processing Operation In the video camera of the present embodiment, various setting values stored as imaging recording mode information are associated with a folder, and when the user selects this folder, these settings are set. The value is set in each required part. Then, the video camera of this example executes a recording control process so that the image thus captured is stored in the selected folder.

The shooting processing operation and recording control processing operation in the video camera of this example according to such a folder selection operation by the user are as shown in the flowchart of FIG. In this figure, the video controller 38 is already in the camera mode (shooting standby state) and the captured image is displayed on the display section 6A by the user's required operation. And

First, in step S201 shown in the figure, the user selects a folder. As a method for allowing the user to select a folder, for example, first, a GUI image of a “folder selection” menu is displayed on the display unit 6A together with a captured image, and the disc 51 is operated in response to the GUI image being operated by the user. Display the folder list for all folders managed above. Then, the user is allowed to select a desired folder from the folder list thus displayed. When the folder selection operation is performed by the user, step S20
Go to 2. At this time, if any folder is not selected because the user does not operate the GUI of the “select folder” menu, the shooting / recording control processing operation after this is “basic”. It is assumed that the imaging record mode information of “folder” is selected.

In step S202, the folder management information is referred to, the image pickup recording mode information associated with the selected folder is read out, and each set value of the image pickup recording mode information is set to the lens block 1 described in FIG. , The camera block 2 and the video signal processing unit 3 are set at required parts. Then, in response to this, in each of the lens block 1, the camera block 2, and the video signal processing unit 3, it is possible to obtain an operation of controlling each required unit so that an operation based on the set value set is obtained. Become. In this way, by transferring the image capture / recording mode information (various setting values) associated with the selected folder to each required unit, the image capture / recording condition corresponding to the selected folder can be obtained.

In this case, for example, if the setting values are the setting items of “exposure” and “focus”, the video controller 38 transfers the parameters of these setting values to the camera controller 25. Then, accordingly, the camera controller 2 controls the operation of the motor unit 12 in the lens block 1, for example, based on these set values.

For example, in the case of setting items such as "image size", "compression ratio", or "color setting", the video controller 38 sets the parameters of these setting values to M.
The data is transferred to the PEG2 (JPEG) video signal processing circuit 33. For example, in the case of "image size", MPEG2 (JP
The EG) video signal processing circuit 33 determines the reduction ratio of the captured image from the parameter, and executes the interpolation process together with the thinning of the image based on the reduction ratio. As a result, image data having a size corresponding to the set value can be obtained. If the setting value of "compression rate" is MPEG2,
The (JPEG) video signal processing circuit 33 executes the image compression processing on the photographed image data at the compression rate based on the set parameters, whereby the image data having the set compression rate is obtained. Like Further, for example, when the set value of the set “color setting” is “sepia”, this MPEG2 (JPE
G) In the video signal processing circuit 33, the color tone of the captured image is converted to generate captured image data in sepia color.

In this way, by the processing of this step S202, the picked-up image data according to the picked-up recording conditions of the selected folder can be obtained. And
The captured image data obtained in this way is displayed on the display unit 6A.
It is also reflected in the monitor image displayed above so that the user can confirm it.

In step S202, the process of setting the set value of the image-capture recording mode information associated with the selected folder in each required part is executed, and in the following step S203, it is determined whether or not there is an operation for ending the camera mode by the user. Monitor. That is, in this step S203, for example, by determining whether or not the camera mode / playback mode switching key on the operation unit 7 has been operated, it is monitored whether or not the user has operated to end the camera mode. If the operation to end the camera mode is performed, the processing operation is ended as illustrated, and if not, the process proceeds to step S204.

In step S204, it is determined whether or not the user has performed a photographing operation. If there is no shooting operation, the process proceeds to step S203 as shown in the figure, and it is monitored whether there is a camera mode end operation.

If a photographing operation is performed, the process proceeds to step S205, and the imaged image data currently generated by the camera block 2 and the video signal processing unit 3 (obtained on the display unit 6A) is stored on the disk 51. Execute the process recorded in. That is, in this step S205, the captured image data currently generated by the camera block 2 and the video signal processing unit 3 as described above is converted into the MD-DATA2 format by the MD-DATA2 encoder / decoder 41. Then, a process of recording this on the disk 51 is executed.

In the following step S206, a process of updating the folder management information stored in the RTO C area of the disc 51 is executed so that the image data thus recorded is associated with the selected folder. As a result, the captured image data is displayed in step S
It is stored in the folder selected by the user in 201. When this process is executed, the process proceeds to step S203 as shown in the figure, and the presence / absence of a camera mode ending operation is monitored. If there is an ending operation, the processing operation is ended.

The above is the description of the video camera according to the present embodiment. As described above, the video camera according to the present embodiment has, for example, “exposure” and “white balance (W
B) ”, and various setting items such as“ image size ”and“ color setting ”that meet the imaging and recording conditions can be set. In addition, various “imaging recording mode information” in which these setting items are compositely set can be registered on the above.

Then, the video camera of the present example makes it possible to set folder management information that enables folder management for the data recorded on the disc 51, and associates this folder with various set values as imaging recording mode information. So that it can be managed. Further, this folder management information enables the further captured image data to be stored in the folder selected by the user before capturing. That is,
In the video camera of this example, when a folder selection operation is performed by the user before shooting, the image shooting operation is performed with various setting values associated with the folder, and the shot image data is stored in the selected folder. Will be stored. Thus, conventionally, when managing a folder of captured images for each imaging / recording condition, the user has two tasks, one is to set each setting item and the other is to store the captured image separately for each folder. According to the present example, this can be realized by a single operation of selecting a folder.

Further, the video camera of this embodiment has a folder editing function as described with reference to FIG. Depending on this folder editing function, the user can create a new folder in which the desired imaging record mode information is associated by setting various setting items (imaging record mode information) that match the desired imaging record conditions. become able to. As a result, the user can automatically allocate the captured image to a desired folder, and the ease of managing the captured image is significantly improved.

Further, in the video camera according to the present embodiment, basically only the image photographed according to the set value is stored in the folder, so that the user can store the image stored in the folder. By playing and watching,
The image of the photographed image can be easily known by the setting values set in the folder. Therefore, before shooting, the user can shoot with various setting values that realize the image by only selecting the folder that stores the image that matches the image that the user wants to shoot. Becomes If the folder management of the present embodiment is not adopted, even if the user finds an image that matches the image he or she envisions, it is not possible to know the setting value of the image ( It is difficult (unless the set value is recorded each time the image is taken), and the effect described above cannot be obtained.

9. Modified Example In the present embodiment, it is assumed that the recording destination of the captured image data and the recording destination of the imaging recording mode information and the folder management information are all the disks 51 in the above description. It is also possible to record these data in the memory unit 100 shown in FIG. Then, in this case, a modified example described below can also be realized.

That is, as a modification, first, only some kinds of image pickup recording mode information and its folder management information are stored in the memory section 100 by, for example, factory preset. As the imaging record mode information, for example, one corresponding to the "basic folder" described in the embodiment and several other basic imaging record mode information (for example, "sport mode", "still life close-up mode") Etc.) only. Then, in accordance with the fact that the disc 51 is first loaded in the deck section 5 in this way, these several types of imaging and recording mode information are copied to this disc 51, and these folder management information is also stored in the disc 51. Write in the RTO C area. That is, the first loaded disk 51 is a master disk for performing folder management, which is a feature of the present embodiment. Therefore, thereafter, the captured image data is recorded only on the disc 51 as the master disc, and the folder editing process can be executed only on the information of the disc 51. By thus making it possible to edit only the preset information copied to the disk 51, it is possible to prevent the preset information stored in the memory unit 100 from being erroneously erased or changed.

Further, as the above-mentioned modified example, the following is possible. That is, first, similar to the modification described above, the memory unit 100 is made to store only several kinds of imaging recording mode information and its folder management information by, for example, factory preset. However, in this case, the image data can be recorded in the memory unit 100, and the folder editing process for the preset information in the memory unit 100 can be executed. Further, in the case of this modification, the deck portion 5
The folder management information stored in the memory unit 100, the imaging recording mode information and the image data managed thereby are converted into a data format corresponding to the disk 51 loaded in the disk 51. Make it possible to copy. On the contrary, the folder management information stored in the disk 51,
Also, the imaging and recording mode information and the image data managed thereby can be copied to the memory unit 100. In this modified example, the user determines whether the recording destination of the captured image data and the storage destination of the imaging recording mode information and the folder management information are the memory unit 100 or the disc 51. It is configured to be selectable.

Further, the following modifications are possible as the present embodiment. That is, as described in Chapter 5 of this specification, by utilizing the fact that the video camera of this example can edit the image data by the script, it is possible to set a special effective setting item (for example, Regarding "color setting" and "blurring setting", a script is added to the image data so as to give these effects. According to this modification, the effects of, for example, “color setting” and “blur setting” are not directly applied to the captured image data, and the script added when the image data is reproduced is read. As a result, image processing based on the script comes to be performed. In this case, for example, if the setting value of "color setting" is set to "sepia", the captured image data itself is recorded in a normal color expression.
The video controller 38 adds a script "display in sepia" to the image data. Then, at the time of reproducing the image data, the script is read by the video controller 38, and the video signal processing unit 3 performs the image processing for expressing the image data in sepia color. As a result, this image data is reproduced in sepia color.

In this embodiment, the photographed image data is automatically controlled to be stored in the corresponding folder. Of course, the movement of the image data between folders is performed. Can be done freely.

Further, in the present embodiment, a video camera is taken as an example of the recording device. However, in addition to this, for example, a digital still camera dedicated to image capturing, image data generation based on a captured image, and The present invention is not limited to this as long as it is a photographing device capable of recording image data.

The setting items illustrated as being settable in the video camera of this example are merely examples, and in addition to these, image data suitable for the shooting conditions and the intended use of the shot image data is generated. The setting item is not limited to this as long as it is a setting item for performing the setting and the setting can be realized in the configuration of the camera. Further, in the above embodiment, as can be understood from the fact that, for example, “shutter speed” is given as a setting item, the case where image data of a still image is originally recorded is taken as an example. For example, it is naturally possible to apply to image data recording as a moving image by setting a setting item suitable for moving image recording.

[0167]

As described above, according to the present invention, for example, exposure adjustment, white balance adjustment, and image size and compression rate adjustment set values for generating image data that matches a predetermined image recording condition. The formed image recording mode information can be stored in a predetermined recording medium. Also,
The image data recorded on the recording medium can be managed in a folder.

Then, by setting the folder management information, the image-capture recording mode information thus stored is associated with the folder managed in the recording medium, and the folder is selected by the user's selection operation. This recording / recording mode information (various set values)
It is possible to generate image data based on. Further, the folder management information allows the image data thus generated to be stored in the selected folder.

Thus, when the user intends to manage the captured images in a folder for each image capturing / recording condition, conventionally, the user needs to perform two tasks: setting the image capturing / recording mode information and assigning the captured image to each folder. According to the present invention, what has been done can be realized by one operation of selecting a folder. As a result,
According to the present invention, it becomes possible for a user to manage captured images significantly more easily than ever before.
