DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an image processing apparatus according to an embodiment of the present invention will be described. The image processing apparatus according to the present embodiment is mounted on a portable video camera in which a camera device unit and a recording / reproducing device unit capable of recording and reproducing images (still images or moving images) and audio are integrated. Take the case as an example. Further, the recording / reproducing device section mounted on the video camera of the present embodiment adopts a configuration for recording and reproducing data corresponding to a so-called mini disk, which is known as a kind of magneto-optical disk. The description will be made in the following order. 1. Disk format 2. 2. External configuration of video camera 3. Internal configuration of video camera 4. Configuration of media drive section 5. Example of disk structure corresponding to this embodiment 6. Thumbnail image generation processing 7. Outline of script Editing process of the present embodiment 8-1. Information input according to guide function 8-2. Editing process

1. Disc format The recording / reproducing device section mounted on the video camera of this example is assumed to be compatible with a format called MD data, which records / reproduces data in correspondence with a mini disc (magneto-optical disc). . As this MD data format, two types of formats called MD-DATA1 and MD-DATA2 have been developed, but the video camera of this example is capable of recording at higher density than MD-DATA1. It is assumed that recording and reproduction are performed in accordance with the format. So first, MD
-Disc format of DATA2 will be described.

FIGS. 1 and 2 conceptually show an example of a track structure of a disk as MD-DATA2. FIGS. 2A and 2B are a cross-sectional view and a plan view, respectively, showing an enlarged portion enclosed by a broken line A in FIG. As shown in these figures, two types of grooves (grooves) are previously formed on the disk surface: a wobbled groove WG provided with wobbles (meandering) and a non-wobbled groove NWG provided with no wobble. It is formed. The wobbled groove WG and the non-wobbled groove NWG
Exist in a double spiral on the disk so as to form a land Ld therebetween.

In the MD-DATA2 format, the land Ld is used as a track. Since the wobbled groove WG and the non-wobbled groove NWG are formed as described above, the track Tr / A is used as the track. , Tr and B are independently formed in a double spiral (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 disk and the non-wobbled groove NWG is located on the inner peripheral side of the disk. On the other hand, the track Tr · B is a track in which the wobbled groove WG is located on the inner peripheral side of the disk and the non-wobbled groove NWG is located on the outer peripheral side of the disk. In other words, it can be considered that wobbles are formed only on one side of the outer circumference of the disk with respect to the track Tr · A, and wobbles are formed only on one side of the inner circumference of the disk with respect to the track Tr · B. . In this case, the track pitch is the track Tr adjacent to each other.
・ It is the distance between each center of A and track Tr ・ B,
The track pitch is 0.95 μm as shown in FIG.
It has been.

Here, the wobbles formed in the groove as the wobbled groove WG are formed based on a signal in which the physical address on the disk is encoded by FM modulation + biphase modulation. For this reason, it is possible to extract the physical address on the disk by demodulating the reproduction information obtained from the wobbling given to the wobbled groove WG at the time of recording / reproduction. Further, the address information as the wobbled groove WG is commonly effective for the tracks Tr · A and Tr · B. In other words, the track Tr · A located on the inner periphery of the wobbled groove WG and the track Tr · B located on the outer periphery share the address information by the wobbling given to the wobbled groove WG. . 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 in a groove, A
Also called DIP (Adress In Pregroove) method.

The identification of which one of the tracks Tr.A and Tr.B sharing the same address information is being traced can be performed as follows. For example, in a state where the main beam is tracing a track (land Ld) by applying a three-beam method, the remaining two side beams trace grooves located on both sides of the track being traced by the main beam. It is possible to make it.

FIG. 2B shows, as a specific example, 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 S
Ps2 traces the wobbled groove WG. On the other hand, although not shown, if the main beam spot SPm traces the tracks Tr and B, the side beam spot SPs1 traces the wobbled groove WG and the side beam spot SP
s2 traces the non-wobbled groove NWG. Thus, the main beam spot SPm
Tracing the track Tr · A and the track T
In the case of tracing r · B, the grooves to be traced by the side beam spots SPs1 and SPs2 are necessarily replaced by the wobbled groove WG and the non-wobbled groove NWG.

Side beam spots SPs1, SPs2
As a detection signal obtained by the photodetector due to the reflection of light, different waveforms are obtained depending on which 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 traces the wobbled groove WG (or the non-wobbled groove NWG), the main beam is moved to the tracks Tr · A,
Which of Tr and B is being traced can be identified.

FIG. 3 shows the main specifications of the MD-DATA2 format having the track structure as described above.
It is a figure shown in comparison with D-DATA1 format.
First, in the MD-DATA1 format, the track pitch is 1.6 μm and the pit length is 0.59 μm / bi.
t. 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 a method of addressing, a method is used in which a groove (track) is formed by a single spiral, and a wobbled groove in which wobbles are formed as address information on both sides of the groove.

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

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

On the other hand, in the MD-DATA2 format which can be supported by the video camera of this embodiment, the track pitch is 0.95 μm and the pit length is 0.39 μm / b.
It can be seen that both are shorter than the MD-DATA1 format. For example, in order to realize the pit length, the laser wavelength λ = 650 nm and the aperture ratio NA of the optical head are set to 0.52, thereby narrowing the beam spot diameter at the in-focus position and expanding the band as the optical system. .

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

Also 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 for recording / reproducing is 589 kB / s. It is said. As a result, a recording capacity of 650 MB can be obtained. Compared with the MD-DATA1 format, this means that a high-density recording of about four times is realized. For example, assuming that a moving image is recorded in the MD-DATA2 format, the moving image
In the case where the compression encoding by 2 is performed, it is possible to record a moving image of 15 minutes to 17 minutes, depending on the bit rate of the encoded data. Also, assuming that only the audio signal data is recorded, the ATR
When a compression process using AC (Adaptive Transform Acoustic Coding) 2 is performed, recording can be performed for about 10 hours.

At the time of recording, the video signal processing unit 3 performs a compression process on the digital image signal supplied from the camera block 2 and the digital audio signal obtained by collecting sound by the microphone 202, and compresses the compressed data. The data is supplied to the subsequent media drive unit 4 as user recording data. Further, an image generated from 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. Further, at the time of reproduction, demodulation processing is performed on user reproduction data (data read from the disk 51) supplied from the media drive unit 4, that is, image signal data and audio signal data that have been subjected to compression processing, and these are reproduced. , And output as a reproduced audio signal.

In this example, as a compression / expansion processing method of image signal data (image data), MPEG (Moving Picture Experts Group) 2 is adopted for moving images, and JPEG (Joint Photographic) is used for still images.
Coding Experts Group). Also, the audio signal data compression / expansion processing method includes ATR
AC (Adaptive Transform Acoustic Coding) 2 shall be adopted.

The data processing / system control circuit 31 of the video signal processing unit 3 mainly controls the video signal processing and the audio signal data compression / expansion processing in the video signal processing unit 3 and the video signal processing unit 3. Executes the process for controlling the input and output of the data passing through. The data processing / system control circuit 31

The video controller 38 is made to execute. The video controller 38 includes, 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). Have been.

As a basic operation at the time of recording in the video signal processing unit 3, image 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 supplies the processed 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 subjected to compression processing in accordance with the MPEG2 format, and a bit stream of compressed data as a moving image (MPEG2 Bit stream). In the MPEG2 video signal processing circuit 33, for example, when extracting image data as a still image from image signal data as a moving image and performing compression processing on the extracted image data, the compressed image data as a still image in accordance with the JPEG format is used. Is generated. It should be noted that JPEG was not adopted and MPEG
As compressed image data in the second format, an I picture (Intra Picture), which is regular image data, may be treated as still image data. MPEG
The image signal data (compressed image data) compression-encoded by the two video signal processing circuit 33 is written into the buffer memory 32 at a predetermined transfer rate and temporarily stored. In the MPEG2 format, as is well known, a so-called encoding bit rate (data rate) is used as a constant bit rate (CBR).
ate) and a variable bit rate (VBR), and the video signal processing unit 3 can cope with these.

For example, when performing image compression processing using VBR, for example, the motion detection circuit 35 performs motion detection on the image data within a range of several tens to several hundreds of frames before and after in macroblock units to determine that there is motion. If this is done, the detection result is transmitted to the MPEG2 video signal processing circuit 33 as motion vector information. In the MPEG2 video signal processing circuit 33, the quantization coefficient for each macroblock is calculated by using the required information such as the motion vector information so that the image data after the compression and encoding has a certain required data rate. It will be decided.

The audio compression encoder / decoder 37 includes:
A / D converter 64 (display / image / audio input / output unit 6)
For example, the sound collected by the microphone 202 is input as digital sound signal data. The audio compression encoder / decoder 37 performs compression processing on the input audio signal data in accordance with 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 is temporarily stored here.

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 a 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. Has a function for Buffer memory 3
The compressed image data and the compressed audio signal data stored in 2 are read out sequentially at a predetermined timing during recording, and transmitted to the MD-DATA2 encoder / decoder 41 of the media drive unit 4. However, for example, the operation of reading data stored in the buffer memory 32 during reproduction and the operation of recording the read data from the media drive unit 4 to the disk 51 via the deck unit 5 are performed intermittently. No problem. The control of writing and reading data to and from the buffer memory 32 is executed by, for example, the data processing / system control circuit 31.

The operation at the time of reproduction in the video signal processing section 3 is roughly as follows. At the time of reproduction, compressed image data and compressed audio signal data (user reproduction data) read out 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
Is transmitted to The data processing / system control circuit 31 temporarily stores the input compressed image data and compressed audio signal data in the buffer memory 32, for example. 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 at a transfer rate at which the reproduction time axis can be matched.
The compressed audio signal data is supplied to a video signal processing circuit 33, and the compressed audio signal data is supplied to an audio compression encoder / decoder 37.

In the MPEG2 video signal processing circuit 33,
Decompresses the input compressed image data,
It is transmitted to the data processing / system control circuit 31. In the data processing / system control circuit 31,
The decompressed image signal data is supplied to the video D / A converter 61 (in the display / image / audio input / output unit 6). The audio compression encoder / decoder 37 performs an expansion process on the input compressed audio signal data,
/ A converter 65 (in display / image / audio input / output unit 6)
To supply.

In the display / image / audio 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 is 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. Thereby, the display of the reproduced image is performed on the display unit 6A. Further, in the display unit 6A, not only an image obtained by reproducing from the disk 51 but also a captured image obtained by photographing with a camera part including the lens block 1 and the camera block 2 is naturally displayed. It is possible to display and output almost in real time. Further, in addition to the reproduced image and the captured image, as described above, a message display such as a character or a character for notifying the user of a required message in accordance with the operation of the device is also performed. Such a message display should be output from the data processing / system control circuit 31 to the video D / A converter 61 so that required characters, characters, and the like are displayed at predetermined positions under the control of the video controller 38, for example. Processing for synthesizing image signal data such as required characters and characters may be performed on the image signal data. That is, in this example, the video controller 38 and the data processing / system control circuit 31 have the functions of a character generator and an on-screen display.

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, if a connection is made to an external monitor device or the like via the video output terminal T1, an image reproduced by the video camera can be displayed on the external monitor device.

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

At the time of recording, the media drive section 4 encodes the recording data in accordance with the MD-DATA2 format so as to conform to the disc recording and transmits the encoded data to the deck section 5. By performing decoding processing on the read data, reproduction data is obtained and transmitted to the video signal processing unit 3.

Recording data (compressed image data + compressed audio signal data) is input from the data processing / system control circuit 31, the recording data is subjected to a predetermined encoding process in accordance with the MD-DATA2 format, and the encoded data is temporarily stored. The data 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 input via the RF signal processing circuit 44 and the binarization circuit 43 is subjected to MD-DAT.
A decoding process according to the A2 format is performed, and the data is transmitted to the data processing / system control circuit 31 of the video signal processing unit 3 as reproduction data. Also at this time, if necessary, the reproduced data is temporarily stored in the buffer memory 42, and the data read therefrom at a required timing is transmitted to the data processing / system control circuit 31 for output. Such write / read control for the buffer memory 42 is performed by the driver controller 46. For example, even when the servo or the like is deviated due to disturbance or the like at the time of reproduction of the disk 51 and reading of a signal from the disk becomes impossible, the read data is not stored in the buffer memory 42 during the period. If the reproduction operation for the disc is resumed, the chronological continuity as the reproduction data can be maintained.

The RF signal processing circuit 44 includes a disk 51

The optical head 53 performs high-level laser output for heating the recording track to the Curie temperature during recording, and performs relatively low-level laser output for detecting data from reflected light by the magnetic Kerr effect during reproduction. . Therefore, the optical head 53

The operating section 7 is provided with each of the operating elements 300 to 300 shown in FIG.
311 and the like, and various operation information of the user by these operators are supplied to, for example, the video controller 38. The video controller 38 supplies, to the camera controller 25 and the driver controller 46, operation information and control information for causing each unit to execute necessary operations according to a user operation.

The external interface 8 is provided so that data can be transmitted between the video camera and the external device. For example, as shown in FIG. It is. The external interface 8 is not particularly limited here, but may be, for example, IEEE 1394 or the like. For example, when an external digital imaging device and the video camera of this embodiment are connected via the I / F terminal T3, it becomes possible to record an image (audio) captured by the video camera on the external digital imaging device. . In addition, image (audio) data reproduced by an external digital image device or the like is captured via the external interface 8 so that MD-
It is also possible to record on the disk 51 in accordance with the DATA2 (or MD-DATA1) format. Further, for example, a file as character information used for inserting a caption can be captured and recorded.

The power supply block 9 supplies a required level of power supply voltage to each functional circuit unit using a DC power supply obtained from a built-in battery or a DC power supply generated from a commercial AC power supply. The power supply on / off by the power supply block 9 is controlled by the video controller 38 in accordance with the operation of the main dial 300 described above.

Information detected by the data reading operation of the optical head 53 from 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 the reproduction RF signal to the binarization circuit 43.

LK is input, error information is obtained by 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 a spindle error signal SPE. In addition, the clock CLK includes, for example, the RLL (1, 7) demodulation circuit 106 and the like.
It is used as a clock for processing in a required signal processing circuit system.

The Viterbi decoder 105 has an equalizer / P

7) The data stream is subjected to demodulation.

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 is developed on the buffer memory 42. The data stream expanded on the buffer memory 42 in this manner 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 descramble / E
The DC decoding circuit 117 performs a descrambling process and an EDC decoding process (error detection process). The data processed so far is the reproduction data DA
TAp. The reproduction data DATAp is transmitted at a transfer rate according to the transfer clock generated by the transfer clock generation circuit 121, for example, from the descrambling / EDC decoding circuit 117 to the data processing / processing of the video signal processing unit 3.
The data is transmitted to the system control circuit 31.

The transfer clock generation circuit 121 is, for example,
When a crystal clock is used for data transmission between the media drive unit 4 and the video signal processing unit 3 and data transmission between functional circuit units in the media drive unit 4,
This is a portion for generating a transfer clock (data transfer rate) having a frequency appropriately determined. Further, it generates a clock of a required frequency to be supplied to each functional circuit unit of the media drive unit 4 and the video signal processing unit 3 according to the operation state of the video camera.

The detection information (photocurrent) read from the disk 51 by the optical head 53 is transmitted to the matrix amplifier 1
07 is also supplied. The matrix amplifier 107 performs required arithmetic processing on the input detection information, thereby obtaining a tracking error signal TE, a focus error signal FE, and groove information (absolute address information recorded as a wobbled groove WG on the disk 51) GFM. Are 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 stored in the ADIP bandpass filter 108.
Supplied to

The groove information GFM band-limited by the ADIP band-pass filter 108 is supplied to an A / B track detection circuit 109, an ADIP decoder 110, and a CLV.
It is supplied to the processor 111. In the A / B track detecting circuit 109, based on the input groove information GFM, for example, the track currently being traced is determined by the method described in FIG.
A, TR or B is determined, and the track determination information is transmitted to the driver controller 46.
Output to The ADIP decoder 110 decodes the input groove information GFM to extract an ADIP signal, which is absolute address information on the disk, and outputs the signal to the driver controller 46. The driver controller 46 executes necessary control processing based on the track discrimination information and the ADIP signal.

The CLV processor 111 receives the clock CLK from the equalizer / PLL circuit 104 and the groove information GFM via the ADIP bandpass filter 108. The CLV processor 111 generates a spindle error signal SPE for CLV servo control based on, for example, 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 performs 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 and the access command from the driver controller 46 input as described above. (A tracking control signal, a focus control signal, a thread control signal, a spindle control signal, and the like) are generated and output to the servo driver 113. In the servo driver 113,
A required servo drive signal is generated based on the servo control signal supplied from the servo processor 112. Here, the servo drive signal includes a two-axis drive signal (two types of focus direction and tracking direction) for driving the two-axis mechanism, a sled motor drive signal for driving the sled mechanism, and a spindle motor drive signal for driving the spindle motor 52. Becomes By supplying such a servo drive signal to the deck section 5, focus control and tracking control on the disk 51 and CLV control on the spindle motor 52 are performed.

When the recording operation is performed on the disk 51, for example, the data processing /
Scramble / ED from system control circuit 31
The recording data DATAR for the C encoding circuit 115
Will be input. This user record data DAT
Ar is input in synchronization with a transfer clock (data transfer rate) generated by the transfer clock generation circuit 121, for example.

Scramble / EDC encoding circuit 11
In step 5, for example, the recording data DATAR is written to the buffer memory 42 and developed, and the data scramble processing and E
DC encoding processing (addition processing of an error detection code by a predetermined method) is performed. After this processing, for example, the ECC processing circuit 116 adds an error correction code according to the RS-PC method to the recording data DATAR developed in the buffer memory 42. The recording data DATaR thus processed is read out from the buffer memory 42 and transmitted to the RL via the data bus 114.
The signal is supplied to the L (1, 7) modulation circuit 118.

The RLL (1, 7) modulation circuit 118 applies RLL (1, 7) 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.

Incidentally, the MD-DATA2 format employs a so-called laser strobe magnetic field modulation system as a recording system for a disk. The laser strobe magnetic field modulation method refers to a recording method in which a magnetic field modulated by recording data is applied to a recording surface of a disk, and a laser beam to be irradiated on the disk is pulsed in synchronization with the recording data. In such a laser strobe magnetic field modulation method, the process of forming a pit edge recorded on a disk does not depend on transient characteristics such as the reversal speed of a magnetic field, but is determined by the laser pulse irradiation timing. For this reason, the laser strobe magnetic field modulation method is compared with, for example, a simple magnetic field modulation method (a method in which a laser beam is constantly irradiated onto a disk and a magnetic field modulated by recording data is applied to a disk recording surface). In this case, the jitter of the recording pit can be extremely reduced. 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 section 4 operates so that a 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 controls the optical head 5 so that the disk is irradiated with a laser pulse synchronized with recording data generated as a magnetic field by the magnetic head 54 based on the input clock.
The third laser diode is driven. At this time, the laser pulse emitted and output from the laser diode is based on a 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 the present embodiment.

5. Next, a description will be given of an example of the structure of a disk 51 according to the present embodiment. FIG. 7 conceptually shows an example of the structure of a disk 51 which is assumed to correspond to the present embodiment. Note that 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 areas are provided as management information areas. In the PTOC, required management information is recorded in a pit form, for example, in a premastered area (pit area) on the innermost circumference of the disk. The contents of the PTOC cannot be rewritten. For example, a magneto-optical recording area in which magneto-optical recording and reproduction can be performed is formed around the premastered area where the PTOC is recorded. Then, first, the RTOC area is provided for a section of a predetermined size in the innermost circumference. The RTOC records, for example, basic information necessary for managing data recorded on a disc. For example, in the case of this example, as data recorded on the disc,
Information for managing a track (which may be synonymous with a file) and a folder (structure for grouping and managing tracks) to be described later during recording and reproduction are stored. The contents of the U-TOC in the management area are as follows:
For example, it is assumed that rewriting is sequentially performed in accordance with the result of data recording on a disc and the result of editing processing such as deletion of tracks (files) and folders.

A data area for recording user data is provided on the outer peripheral side of the RTOC.
In the present embodiment, this data area is a volume folder (Volume Folder) located in one root folder.
er). In the present embodiment, a volume 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 is stored as folders and tracks under the volume folder except for those managed by the PTOC and RTOC.

In the volume folder, first,
A predetermined size (for example, 12 clusters) at a physically innermost position (a management track priority area near the RTOC)
Volume Index Trac
k) is placed. The volume index track is defined as an area in which sub-management information is recorded, for example, if the above-mentioned PTOC and RTOC are the main management information, and includes a track (file), a folder, and auxiliary data (Auxiliary Data). And a table in which information for managing packet data forming a property, a title, and a track related to the track is recorded.

Also, at least the first one cluster is RT
As a track recorded so as to be located in the management track priority area near the OC, a thumbnail track (Thumb
nailPicture Track) can be placed as an option. In the present embodiment, one still image reduced by a predetermined resolution can be included as a thumbnail image in association with each file recorded on the disk. The thumbnail image is treated as a representative image for making the file visually recognizable. The thumbnail track is recorded together with index information indicating the association 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 stored thumbnail images and the like.

For example, image / audio data recorded by the user by photographing or the like is managed on a file basis, 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. In the disk of the present embodiment, a text file such as a document can be stored as a file (track) in addition to moving image data, still image data, and audio data. FIG. 7 shows a state in which a certain file is represented as one track and this track is stored in a certain folder. As described above, the folder has a structure for managing tracks or folders in a group. Therefore, in the structure below the volume folder, an arbitrary number of tracks or folders is stored within the range defined by the maximum number of records that can be stored in the volume folder and the maximum number of levels in the folder hierarchical structure.

An auxiliary data track storing auxiliary data (Auxiliary Data) is stored in the volume folder.
(Auxiliary Data Track) is placed. The information to be stored in the auxiliary data track is arbitrary depending on, for example, an application to be actually applied. In the present embodiment, script information as playback control information is stored.

By the way, the PTO, which is the management information described above,
The information stored in the C, RTOC, or even the volume index track (these information is collectively referred to as “management information” in the present embodiment) is read, for example, when a disc is loaded. 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. Then, at the time of data recording or editing, the management information stored in the buffer memory is rewritten according to the recording result or the editing result, and then, at a predetermined opportunity and timing, the management information is rewritten to the buffer memory. The management information of the disk 51 is rewritten (updated) based on the content of the held management information (however, P
No update is performed for the TOC).

It should be noted that the example of the disk structure shown in this figure is merely an example, and the physical positional relationship of each area on the disk may be changed according to actual use conditions and the like, and data is stored. The structure can be changed.

6. Thumbnail Image Generation Process The thumbnail image stored in the thumbnail track shown in FIG. 7 can be generated by the video camera of the present embodiment. Here, the thumbnail image generation process will be described. deep. Here, a case where a thumbnail image of an image file once recorded on a disc is generated will be described.

As described above, the management information (PTOC, RTOC, volume index track) recorded on the disk 51, for example, is read out at a predetermined timing such as when the disk is loaded, and is stored in the buffer memory 42 (or the buffer memory 42). 32).

The driver controller 46 refers to, for example, management information stored in the buffer memory 42 and records image data designated as a thumbnail image for a file from which a thumbnail image is to be generated. By obtaining an address on the disc and accessing the address to execute a read operation on the disc, image data as a thumbnail image generation source is obtained. This image data is
The data is sequentially transmitted from the media drive unit 4 to the video signal processing unit 3 and supplied to the data processing / system control circuit 31. Unless otherwise specified, the image data specified as the thumbnail image generation source by the management information is assumed to specify, for example, the first frame (or field) image data in the file.

The data processing / system control circuit 31 first controls the MPEG2 video signal processing circuit 33 for the supplied screen data,
Decompression processing according to the EG2 format is performed, and data decoded to the level of image data in field image units is obtained.

For example, at the stage of image data decoded to the level of the field image unit, usually,
The data is data having an image size (the number of pixels) enough to be displayed on a display screen at almost full size. Therefore,
After the full-size image data in the unit of the field image is obtained, reduction processing is performed on the full-size image data so that processing is performed so that the thumbnail image size actually required is obtained. Become. In order to reduce the image size, for example, the original full-size image data is sampled at appropriate timing for pixel data, and a signal is generated to reconstruct the image data using the sampled pixel data. What is necessary is just to perform a process.

Then, for example, the video controller 38
Generates index information (described with reference to FIG. 7) for the thumbnail image data thus obtained,
Control is performed so that the thumbnail image data is recorded on the thumbnail track of the disk together with the index information. In this way, thumbnail image data corresponding to each file is obtained and recorded on the disc.

In this embodiment, as can be seen from the above description, in addition to image data (including audio data), audio data using only audio, and character information data can be recorded as a file. However, for example, when there is no image data from which the thumbnail image is generated in the file such as audio data and character information data, for example, it is visually determined that the data is audio data or character information data in advance. Prepare image data of a pattern that can be recognized by the user (for example, the RO of the video controller 38).
M, or stored in a predetermined area of a disk), and this image data may be used as a thumbnail image.

7. Outline of Script In the present embodiment, it is possible to perform an editing process on a file (mainly a recorded file) recorded by the video camera, such as specifying a reproduction order and giving a required special effect at the time of reproduction. In performing the editing as described above, in the present embodiment, a script is provided as playback control information capable of giving a required playback output mode for a recorded file. In a 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. In the editing stage, the content of the script is updated to execute the editing process. In addition,
Here, the “script” refers to a procedure writing structure described in a predetermined programming language in order to reproduce and output moving image data, still image data, audio data, and even document data at the same time. Is done.

First, a script used as reproduction control information in the present embodiment will be schematically described.

In this embodiment, SMIL (Synchronized Multimedia Integration Language) is used as a script.
ge). SMIL is a language standardized by W3C (Internet standardization organization) in order to realize, for example, television program broadcasting and presentation on the Internet.
It is intended to realize a chronological presentation or the like based on the grammar of a (super set of TML).

First, the scheduling includes <seq>, <
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 the tags is reproduced synchronously.

Here, for example, in a file assumed to be recorded on a disc, video1, video1
2, for a file of image data represented as video3, video1 → video2 → video3
If you specify to play in the order of Or The description is made as follows.

Also, the file video1 → video

For audio1 which is a file of audio data
If you want to play simultaneously as a post-recording track, Will be described as follows.

A description is also provided for specifying a file to be reproduced synchronously with a certain file, for example, starting from a position several seconds after the reproduction of the certain file. For example, in a case where a caption (for example, an image as character information) is displayed 5 seconds after the image file of video1 is displayed (reproduced), <par><videosrc = “video1”><imagesrc = The description is made as follows: "scratch1" begin = "5s"></par>.

For example, if the user instructs to display the file picture 1 as a still picture file for 5 seconds, <image src = “picture 1” dur
= “5s”>.

[0099] Also, when a so-called frame mute is used to extract and reproduce a part of a certain moving image file, "range" is used. For example, SMPTE (Society of Motion Pictu
re and Television) standard, <video src = “video1” range
= "Smpte: 10: 07: 00-10: 07: 3"
3 ">.

To repeat a file by designating a certain file, "repeat" is used. For example, vi
If the file of video1 is repeated 10 times, <video src = “video1” repe
at = “10”>.

In the present embodiment, such a script called SMIL is used to execute a display control for giving a required display form as a thumbnail display. For this reason, for example, in the video camera system of the present embodiment, this S

, A subset of XML is prepared. For example, the program may be stored in advance in a 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 an application layer of a disc and read out.

In the present embodiment, such a script is generated or updated by the video controller 38 in, for example, an editing stage (or a stage in which a recording operation is being performed). It is to be kept in the area. Then, the script held in the buffer memory 32 in this manner is recorded on the disk at a predetermined opportunity or timing. The script data is stored as a script file for the auxiliary data track (Auxiliary Data Track) described with reference to FIG.
By recording the script on the disk in this way, the next time the disk is newly loaded, the script recorded on the disk is read out, for example,
By holding the data in the buffer memory 32 and referring to the data, it is possible to perform editing and reproduction in accordance with the reproduction order and the like obtained by the previous editing.

8. Function for creating video work of present embodiment 8-1. Overview Next, a description will be given of a video work creation function (editing function) according to the present embodiment. For the function of creating a video work according to the present embodiment, an editing application program (an input instruction program and an editing program) is prepared. The editing application program is a program for editing a video work of a certain genre, and creates a video work according to a preset script. Specifically, at the time of shooting a source (recorded file) serving as a material of a video work, a GUI as a guide function is displayed based on the screenplay so that the user can appropriately perform necessary input operations. The user is prompted to take a picture. Information (including character information) obtained by an input operation performed in accordance with the GUI and a recorded file (image / audio data file) obtained by shooting are handled as editing material information. In the actual editing process, a video work is created by performing editing using the editing material information according to the script structure. However, in this embodiment,
At the time of the editing process, the reproduction order of the recorded file and various editing effects (for example, superimposition and BGM insertion) are specified by the above-described script, instead of directly performing the editing process on the recorded video file. The camera performs editing and reproduction by interpreting the script and performing appropriate signal processing as appropriate.

In the present embodiment, the editing application program is recorded as one file (track) on the disc. A file and a script file recorded by the guide function of the editing application program are also recorded on the same disk. That is, in the present embodiment, an application program for editing a video work for a specific purpose is recorded on a disc, and data and a script as a material necessary for the editing can be recorded. This is to provide a disc specialized for creating and playing back a video work of this specific genre. For the editing application program, for example, a nonvolatile memory may be provided on the video camera side, and the nonvolatile memory may be stored in the nonvolatile memory. That is, it is conceivable that the video camera itself is configured to have a function for creating a video work of a certain genre.

8-2. Input of Information and Photographing According to Guide Function Hereinafter, the process of creating a video work in the present embodiment will be described along one specific example.
Here, as an example, a case in which a golf competition pattern is created as a video work will be described. Therefore, in this case, the user prepares a disc in which an editing program for a golf competition is recorded and which is specialized for creating a video work of the golf competition. Also here, A, B
The case where three users C and C perform a golf competition will be taken as an example. Hereinafter, the term “user” refers to a person who handles the video camera among at least one of A, B, and C.

First, an example of a procedure in which the user inputs information for editing (input of operation information and shooting of editing material) while performing a golf competition will be described with reference to FIGS. In the following description, a program corresponding to an input operation or the like will be sequentially shown as necessary. It is assumed that the program is compatible with the configuration described. Therefore, the variable definition and the class definition in this example in this program will be shown here first. int: an integer video: a variable that holds a reference to a video track class Party {video beginning comment; // a reference to a video track where a comment before going around the course was taken String name; Handy video party shot of party members // reference to video track of starting hole tee shot int teeth_quality; // quality of starting hole tee shot int score [18]; // score of all holes of party member｝ class Hole Ｉｎ int par; float length;｝ class Track ｛video track; int type; int hole; int sho number; int shottype; int personnumber;｝ list of variables int number of parties; // number of parties String course; // name of courses Party party []; // information on members of the number of parties Track [t]; Hole hole [] of the track taken at the end of this course // Information on this course (18 holes)

For example, users (A, B, C)
May carry the video camera of the present embodiment and the disc of the present embodiment (hereinafter simply referred to as “golf disc”) specialized for creating a video image of a golf competition to go to a target golf course. To be. For example, at a stage before a round at a golf course, a golf disc is loaded into a video camera, and a guide function display of an editing application program recorded on the disc is operated by a predetermined operation. As an operation for this, for example, an editing program is selected and reproduced according to a predetermined operation procedure for normal file reproduction. As a result, the editing program is started, and for example, a menu screen of the editing program is first displayed. Then, the user operates the menu screen to call up the guide function display.

As a result, for example, the guide display shown in FIG. 8 is performed on the display unit 6A according to the editing program. The guide display shown in FIG. 8 is for inputting various information required for editing before the round.

Here, first, the display shown in FIG. 8A is performed as a guide display for preparation input before the round. The guide display in FIG. 8A is for inputting the number of people who will round the course. In this case, 3
Since the user is a person, the user performs an operation on the N screen to input that the user is three. As the operation procedure at this time, for example, buttons of “2 persons”, “3 persons”, “4 persons” and “5 persons” and an input window of “more persons” are displayed. By operating the click key 310, a cursor (not shown) is arranged at the button of “three”, and in this state, a click operation is performed on the center portion of the cross / click key 310. In other words, "three"
Select the button and click. This allows
Information that the number of people who make the round is three is input. The program corresponding to this input operation is, for example, numberofparity = 3; Note that the description of such a program, which will be described hereinafter, needs to be stored in order to be used for creating a script described later. What is necessary is just to comprise. Alternatively, it is also conceivable to store and hold in a predetermined area of a memory (for example, the buffer memory 42) inside the video camera.

When the input operation for the guide display of FIG. 8A is completed and, for example, a click operation is performed on a button displayed as “Next”, the display is switched to the guide display shown in FIG. 8B. The guide display in FIG. 8B prompts the photographing of a scene in which each member is expressing an aspiration. For example, here, the current captured image (currently the image signal obtained by the lens block 1 and the camera block 2) is displayed, and then “1” is displayed.
"Shoot today's ambition in about 5 seconds." Is displayed. This “shooting designation frame” is displayed for designating an ideal composition for a subject as a variant material, and is not displayed during actual editing / reproduction (the same applies to the above character display). Display section 6A on which this display is being performed
Is monitored, the user takes a picture of one member who expresses his resolution in about 5 seconds in such a composition that the member almost fits in the designated photographing frame. The recorded file (moving image / audio file) taken here is
For example, video 1 and a file name are added and recorded on a disc to be stored. beginning comment = vid
eo1; is associated with the comment before the first round.

Here, assuming that the photographing of a certain member is completed, the display shown in FIG. 8C is performed as a guide display. In other words, it is asked whether or not the video that has just been shot is satisfactory to the user. At this stage, the user can click on the “Review” button to play back and check the image that was just shot, and if the shooting result is unsatisfactory, click the “Retake” button. By the operation, shooting in the guide display state shown in FIG. 8B can be resumed. Here, if the photographed image is convincing to the user as a result, the user exits the guide display of FIG. 8C by a predetermined operation and shifts to the guide display shown in FIG. 8D.

In the guide display shown in FIG. 8 (d), it is possible to input characters as information on the member just taken, such as a name and a handy, which are actually prepared as input items in advance. Has become. In the present embodiment, characters can be input using the jog dial 311 shown in FIG.
In this guide display, it is assumed that a photograph of the face of the member is displayed. The image of the face photograph can be obtained by generating a thumbnail image from image data of a file in which a scene in which the ambition was previously mentioned is recorded. Such processing is automatically executed by the editing program. Then, when the character input for the required items is completed, for example, a click operation is performed on an “OK” button. At this time, as a program, for example, if a character input is performed for the member photographed for the first time, the program is designated as "party [0]. name = “A”; party [0]. handycap = 20; The member name and handicap are registered.

Here, the guide display shifts when a click operation is performed on the “OK” button.
If the shooting of the scenes expressing the aspirations of all the members has not been completed yet, the process returns to FIG. 8B. In this case, since there are three members, FIG. 8 (b) → FIG.
(C) → The user repeats the procedure described with reference to FIG. 8 (d) three times. In this way, when we have completed the shooting of a scene about all members,
As a program, party [1]. beginning comment = vid
eo2; party [2]. beginning comment = vid
eo3; is recorded as video2 and video3, describing the resolutions of the second and third members, and characters for the second and third members in the guide display of FIG. 8D. According to the input, party [1]. name = “Mr. B”; party [1]. handycap = 8; party [2]. name = “C”; party [2]. handycap = 15;

As described above, FIG. 8B → FIG.
(C) → After the procedure described with reference to FIG. 8 (d) is repeated for all the members, if the “OK” button shown in FIG. 8 (d) is operated, the guide display of FIG. 8 (e) is displayed. Transition.

In the guide display of FIG. 8E, a course to be rounded is selected. For this reason,
In the guide display shown in FIG. 8E, golf course course candidates are displayed. The course of the golf course displayed as a candidate here is assumed to be stored as a database in the editing program.
For example, information such as the number of holes for each course, the number of yards (distance) for each hole, and the number of pars is stored. The user operates, for example, the cross / click key 310 on the guide display shown in FIG. 8E to select a course of the golf course to be rounded from here and perform a click operation (decision operation). Here, it is assumed that “Kashiwa Country Club” has been selected and determined as the course of the golf course. As a result, the program is registered as follows: course = “Kashiwa Country Club”;

As described above, this editing program has a database of courses. In this case, since the Kashiwa Country Club has been registered as described above, all of the Kashiwa Country Club halls have been registered. full length,
Data such as the number of pars can be accessed. About these databases, as a program, hole [? ]. par hole [? ]. It can be accessed from variables such as length. Input operation up to course selection as described above (FIG. 8 (e))
Is completed, in this case, for example, as shown in the guide display of FIG. Is notified that all of the input operations have been completed.

Next, the guide display during the round and the procedure of the user according to the guide display will be described with reference to FIGS. 9 and 10. For example, after the input operation shown in FIG. 8 is completed, a guide display as shown in FIG.
An instruction is given to take a tee shot of the first hole. Then, in the subsequently displayed guide display of FIG. 9B, an operation for selecting a member to be a subject is prompted. Also, in the guide display of FIG. 9B, the face photograph of each member is displayed using the thumbnail image generated from the image data of the file in which the scene in which the ambition was described earlier was recorded. Then, the cursor is moved with respect to the face photograph of each member, and the selection decision operation is performed.

When the selection and determination operation is performed on the guide display shown in FIG. 9B, the display unit 6A changes to the guide display shown in FIG. 9C. Please take a picture at about the time ", and a shooting instruction frame by superimpose and a shooting instruction frame for designating the composition are displayed. Then, in this state, the user takes an image of the player performing a tee shot (performs a recording operation). Also, in this case, when the recording operation is completed, the guide display in which the “review”, “retake”, and “OK” buttons are displayed as shown in FIG. Fig. 8 (b) → (c)
This is the same as the case of photographing according to the procedure of

In this case, when the “OK” button is operated in the guide display shown in FIG.
The display shifts to the guide display of (e), and the user can input the skill level of the tee shot just shot. Here, four buttons of "great", "OK", "Choro", and "Tempura" are presented as candidates, and the user selects a desired button from these buttons and performs a click operation (decision operation). To be. FIG. 9 (b) → FIG. 9 (c) → FIG. 9 (d) →
The guide display display shown in FIG. 9E is repeated for the number of members (three times in this case) so that a tee shot of each member can be taken. 9 (b) → FIG. 9 (c) → FIG. 9 (d) → FIG. 9 (e), the procedure according to the guide display shown in FIG. It is assumed that the input has been completed. At this stage, the recorded files of the tee shots of the three members are video4, v
The recording is performed on a disc with names of video5 and video6. Then, in the program, party [0]. teethshot = video4; party [1]. teethshot = video5; party [2]. In a format of “teeshot = video6;”, the recorded file is associated with the shot of the shot. FIG.
Based on the input operation for the guide display in (e), for example, the function [party [0]. teethshot_quality =
OK; party [1]. teethshot_quality =
GREAT; party [2]. teethshot_quality =
The shot evaluation is registered in a format such as CHORO; In this case, A's shot is OK for OK.
The click operation on the button is performed, and the result of the click operation on the “Great” button is shot for the shot of Mr. B, and the result of the click operation on the “CHORO” button is reflected for the shot of Mr. C.

When the procedure relating to the tee shot is completed as described above, for example, a guide display shown in FIG. 9F is performed thereafter. In the guide display, thereafter, the user is prompted to arbitrarily photograph a favorite scene (this is synonymous with recording a captured image). In this case, as a candidate for the shooting content, a “landscape” button corresponding to shooting of a landscape, a “comment” button corresponding to shooting of a scene commented by the player, and an optional And a "shot" button corresponding to shooting of the shot. The user selects one of these buttons and performs a click operation in accordance with the content to be photographed.

If a click operation is performed on the “landscape” button under the guide display shown in FIG. 9F, for example, the guide display will be as shown in FIG. 10A.
It is a content that encourages shooting of the landscape. Here, a telop “Please take a landscape” is displayed for the current captured image. The user only has to monitor the captured image while looking at the display section 6A on which the guide display is displayed, and shoot the desired scenery.

Also, if a click operation is performed on the "comment" button on the guide display shown in FIG. 9 (f), a scene in which the player is commenting as shown in FIG. Is displayed. In this guide display, for example, a telop “Take a comment” for the current captured image and a shooting designation frame for deciding the composition are imposed and displayed. The user photographs the commenting user while monitoring the guide display. Although not shown here, when photographing the “comment”, for example, FIG.
By displaying a guide display similar to (b),
An input operation for specifying which player's comment is to be taken is also performed.

Alternatively, if a click operation is performed on the “shot” button on the guide display shown in FIG. 9F, the display shifts to the guide display shown in FIG. 10C. In this guide display, a display for prompting the user to input a hole number at which a shot to be taken is performed, the number of hits in that hole, and a button display for inputting the type of shot (here, “tee”, “iron”) "Trouble" and "Pat" buttons are prepared. Also, although not shown here, for example, a guide display according to FIG. 9B is displayed to specify which player's shot is to be taken. 10 is prompted.
When the input operation for the guide display of (c) is completed, as shown in FIG.
A guide display in which a telop prompting to shoot in about a second and a shooting designation frame are imposed on the captured image is displayed,
The user takes a shot. It is to be noted that the description is omitted here to avoid duplication of description, but also in this case, when the shooting of the shot by the player is completed, for example, the review and the retaking as shown in FIGS. 9D and 9E are performed. And a guide display for inputting shot evaluation may be displayed. Then, the user can perform the above-described processing in FIG.
The procedure described with reference to (f) to FIG. 10 (d) is repeated.

Here, examples of the program contents obtained by the procedures shown in FIGS. 9 (f) to 10 (d) will be described. First, assuming that a trouble shot of Mr. A in the second shot of the fourth hole is recorded as video7 as a countermeasure when a shot is taken, for example, track [0]. track = video7; track [0]. type = SHOT; track [0]. hole = 4; track [0]. Shotnumber = 2; track [0]. Shottype = TROUBL
E; // TROUBLE means a trouble shot. track [0]. personnumber = 0; /
/ Party [0] is Mr. A. Will be registered.

Then, if Mr. B's comment on this shot is recorded as video8, for example, track [1]. track = video8; track [1]. type = COMMENT; track [1]. The additional information is registered as follows: personnumber = 0;

Further, if it is assumed that the scenery is photographed as video 9 after photographing the comment of Mr. B, track [2]. track = video9; track [2]. type = SCENE; track [2]. hole = 4; // additional information is registered in such a manner as to indicate at what hole the image was taken. The additional information includes a content indicating at which hole the scene is photographed. The information of the hole at which the scene is photographed is based on the photographing situation (for example, The information can be recorded by analogy with information such as a hole number input corresponding to a shot shot earlier.

Then, for example, when a predetermined input operation (not shown here) corresponding to the end of the play is performed or when it is estimated that the play has ended from the shooting conditions so far, first, A guide display for score input shown in FIG. The user operates the jog dial 311 with respect to this guide display to input a score value for each member. It should be noted that such a score input screen may be configured so that it can be called up as needed even during play so that a score can be input as appropriate. The program corresponding to the score input includes the following: [0]. score_hole [1] = 3; party [0]. Recording is performed as follows: score_hole [2] = 5;

When it is determined that the input of the scores for all the members has been completed, for example, a guide display shown in FIG. 10F is displayed. This guide display display is for prompting the photographing of the scene where each member is commenting after the play. In this case, the members to be photographed from now on (see FIG. 9B) Is displayed first as a thumbnail image). When the user performs an operation on this screen to select a member to be a subject, for example, as a guide display, a guide display prompting shooting for several seconds as shown in FIG. A guide display for prompting confirmation after photographing as shown in FIG. 9D is performed, and the user confirms photographing and recording state, retakes, and the like according to the display. Then, by following the same procedure, a scene in which all members are commenting is taken. For example, three members' comments are photographed in the order of A, B, and C, and these are respectively file names video10, video11,
Assuming that the program is recorded as a video12 recording file, the program is: party [0]. endcomment = video
10; party [1]. endcomment = video
11; party [2]. endcomment = video
12; is associated with each recorded file in the following manner.

Upon completion of all the procedures so far, program information based on an input operation of necessary information for creating a video work, and a recording file (image / audio information) serving as an editing material, as editing material information. Is obtained.

When the guide display shown in FIGS. 8 to 10 is performed, actually, based on the exposure control value stored in the editing application program, the lens block of the video camera apparatus is used. It is assumed that the program AE (Automatic Exposure) function is being corrected. In other words, according to the script set as the editing application program, it is possible to easily assume under what conditions shooting for collecting editing materials is performed under the guide display. For example, in the case of a golf competition, the situation is to be photographed outdoors. Therefore, a correction value for the AE suitable for the predicted shooting situation is prepared in advance in the editing application program, and the AE correction is automatically performed based on this correction value during shooting according to the actual guide display. For example, in the case of a golf competition, an AE correction value that is optimal for outdoor shooting is prepared in an editing application program, and the correction controls the program AE. As a result, for example, the AE program is controlled so as to maintain an almost optimal state even if the user does not particularly perform an operation such as a program change of the AE. It is something that can be obtained.

8-3. Editing and playback (playback as video work) And in the video camera device of the present embodiment,
According to the script set under the editing application program, the input information obtained as described above is used to perform an editing process for creating a video work using the recorded file as a material. This editing process is realized by a process of constructing a script for designating a playback timing including a playback order of each recorded file, a superimpose on the reproduced recorded file, and the like. Then, by interpreting the script obtained in this way and executing image processing for reproducing the recorded file and for giving a special effect, the reproduction as a video work is performed. The created script is recorded on an auxiliary data track (Auxiliary Data Track) of the disc in which the corresponding editing application program is stored, so that the script is stored.

[0132] First, an example of a playback mode of a video work created by a script described according to the procedure described with reference to Figs. 8 to 10 will be described with reference to Figs. The description contents and the script generation method corresponding to the example of the reproduction mode of the video work described below will be described later.

For example, the user edits a golf editing disc used for shooting at a golf course (at this stage, a recorded file serving as an editing material and a script for editing a video work have already been recorded. ) Is loaded into a video camera and an operation for reproduction is performed. In response to this operation, the video camera reads the script from the disk, and performs the playback of the recorded file and the image / audio signal processing while interpreting the script, thereby reproducing the following video work. Realize.

In this case, first, an opening title as shown in FIG. 11A is displayed together with the output of the sound effect. Subsequently, an image of the member introduction is displayed as shown in FIG. 11 (b). here,
A photo of the member's face is displayed along with its name. The face photograph of this member may be the one used in the guide display of FIG. 9B. That is, FIG.
The thumbnail image used for the guide display in (b) is the one recorded on the thumbnail track of the disc at the time of input operation and shooting at the site.

Subsequently, as shown in FIG. 11 (c), for example, a scene in which Mr. A talks about his resolution is a moving image (video1).
(Recorded file recorded as). At this time, since the recorded file of video 1 is being reproduced, the voice of Mr. A expressing his aspiration is output in synchronization with the voice. Here, a character display (superimpose display Simp) is performed as in "Mr. A who talks about today's enthusiasm". The display of the scene in which this member talks about his aspiration follows A, followed by B and C
Also performed for (video2, video3
Playback).

After that, the scene of the tee shot of each member is displayed. For example, here, FIG.
After the display of the comment scene of each member's aspiration shown in FIG. 11, a state in which the scene where Mr. A is making a tee shot is displayed as shown in FIG. 11D (video 4). . Here, "1H 300yd
The superimposed display Simp indicating the information of the hole as in "par5" and the superimposed display Si explaining the scene "A tee shot!"
mp has been done. Further, a superimpose display Simp is provided by the character "GREAT" which effectively explains that the shot is wonderful. For example, the superimpose display Simp of this "GREAT"
Is displayed in response to an input operation in accordance with the guide display shown in FIG. 9E. In this embodiment, as an editing effect, for example, the superimposition of such a design is performed. The display Simp is configured to be automatically displayed. The display of such a tee shot scene is also performed sequentially for all the members (videos 5, 6). At this time, since the basic display is obtained by playing the recorded file, the recorded sound may be played back and output at the same time, and this can be easily realized. It is.

Thereafter, for example, the image and sound of the recording file arbitrarily photographed at the site after the tee shot are
It is output with some required editing effects. In this case, after the tee shot scene of each member shown in FIG. 11D is displayed, as shown in FIG. 12A, the trouble shot scene (video) of Mr. A is performed.
7) is displayed. Here, the content indicating the information of the hole as the superimposed display Simp and the content indicating that Mr. A is in a trouble shot together with the current score are inserted.

Subsequently, for example, as shown in FIG. 12 (b), by playing back video8, a video of Mr. A commenting after the trouble shot is displayed, and the voice of the comment at this time is also output. Is done. Here, as the superimpose display Simp, a description of the current situation, for example, "Mr. A commenting",
What indicates the progress of the play and the score, such as "4H end current score + 8", are displayed.

In this case, following FIG. 12B, a moving image (or a still image) of a green of a certain hole is shown in FIG. 12C as a scene taken by the user as video9. Is displayed as shown. In this case, BGM prepared by the editing application program is appropriately selected and output as audio. At this time, only BGM may be used as the audio output, or BGM may be combined with the audio obtained by reproducing from the video 9 recorded file and output.

If such display is performed and video output is performed until the end of the game, the display screen is, for example, as shown in FIG. A score indicating the performance of each member so far is displayed. This score display is obtained based on the information obtained by the score input operation shown in FIG.

When the score display is completed, a display as shown in FIG. 13B is performed as the ending title. Here, for example, an image of a smiling character prepared by an editing application program is displayed, and
"So, this time,""Mr. B won!"
A superimposed display Simp that effectively shows the winner is displayed. This winner is specified by referring to the score of each member obtained by the score input operation shown in FIG. When the display of the ending title ends, the reproduction as the video work ends.

8-4. Next, the contents of the script for realizing the display as the video work shown in FIGS. 11 to 13 will be described. As described above, in the video camera of the present embodiment, FIGS.
By using the input information obtained according to the guide display as shown in FIG. 0 in combination with the file as the editing material recorded as the recording file, meta information called a script file is configured. The construction of this script file can be performed, for example, by executing the editing application program at a necessary opportunity (preferably, immediately after) after the information input and shooting according to the guide display are completed. Video controller 3
8 is executed by using a subset of XML installed therein. Here, JAVA A431ppl is added to the superimpose based on the SMIL grammar.
An example using et will be described. <Seq> // Information used is coursename, then time automatically recorded at the time of shooting // titleshow applet displays title // section 1 (corresponding to FIG. 11 (a)) <applet code = ″ titleshow "<param name =" course "value =" Kashiwa CC "name =" date "value =" 98/4/4 08:00:00 "name =" caption "value =" golf competition "/// applet> / // Information used is "party" // Thumbshow applet displays thumbnail of specified image // Section 2 (Fig. 11 (b)) <applet code = "thumbshow"><param name = "partyname" val ue = "A, B, C" name = "partythumb" value = "video1, video2, video3"></applet> // The information used is included in the party // specify the applet applet <Pa> // Display image and caption at the same time <video src = “video2”> // Comment before start <applet code = “superimpose”><Param name = "bottomcaption" value = "Mr. Fukushima talking about today's enthusiasm"</apple></par> // Repeat for three people. // Section 4 (FIG. 11 (d)) <par> // Display image and caption simultaneously <video src = “video5”> // A tee shot <apple code = “superimpose”><param name = ″ bottomcaption ″ Value = ″ A tee shot ″> param name = ″ centercaption ″ value = ″ great ″ paramname = ″ topcaption ″ value = ″ 1H 300 yd par5 ″> // apple> Information contained in the "party" // superimpose applet superimposes the specified text // section 5 (Fig. 12 (a)) <par> // image and caps <Video src = “video7”> // Troubleshooting <apple code = “superimposse”><param name = “bottomcaption” value = “current A of the 2nd trouble +8”> param topcaption "value =" 4H 180yd par3 "></applet></par> // The information used is included in the party // superimpose applet superimposes the specified text // section 6 (Figure 12 (b)) <par> // Display image and caption at the same time <video src = “video7”> // Troubleshooting <apple code = “superimpose”><pa ram name = "bottomcaption" value = "score at the end of 4H + 8" param name = "topcaption" value = "Mr. A to comment"><//applet><//par> // included in the editing application program in advance.

The super in the above script
The image processing for superimposing the text specified by the impose applet may be performed, for example, as follows.

One uses a function of a character generator and an on-screen display realized by the video controller 38 and the data processing / system control circuit 31. That is, in the video controller 38, the interpreted script is su
If the text specified by the peripose applet is to be displayed, the character / symbol information of the specified text is generated. And
The generated characters / symbols are displayed at predetermined positions on the image of the recorded file being reproduced.
The control of the data processing / system control circuit 31 is executed.

The characters of the superimposed display Simp designed such as “Kashiwa CC Golf Competition” in FIG. 11A and “GREAT” in FIG. It is also possible to generate the image data according to the following, for example, for the special design as described above, as a file in a required directory, as data of the application program for editing in advance The image data is read out as needed, and the recording file (video) is read.
If the processing is performed so as to be superimposed on the reproduced image of o) (such image processing is performed by the data processing / system control circuit 31), the processing load of the video controller 38 and the data processing / system control circuit 31 is reduced. It becomes lighter.

For example, the above-described superimpose processing is applied mutatis mutandis to realizing the display of a telop in a guide display with a captured image as a background and the display of a photographing designation frame previously shown in FIGS. Is done. That is, the video controller 38 executes a control process for reading out the telop and the image data file of the designated shooting frame prepared by the editing application program from the disk and supplying the read data to the video signal processing unit 3. The video signal processing unit 3 performs a decoding process on the supplied image data file, for example. Then, in the data processing / system control circuit 31, under the control of the video controller 38, the decoded telop or the image data of the designated photographing frame is displayed at a required position on the captured image supplied from the camera block. Perform image synthesis processing. Then, the image data is displayed and output on the display unit 6A.

8-5. Next, a method of generating a script obtained in an environment in which the editing application program according to the present embodiment is running will be described. Here, as an example, the case of generating the script contents for realizing the display as the video work shown in FIGS. 11 to 13 will be described as an example. For each script section, the input variables and other sets Let's look at how the wizard is generated from this information. Here, the parameter calculation method is described in C ++ language. Section 1 (FIG. 11A) course = co
// The date according to the course selected by the user date = getdate (); // Receive the date from the calendar function provided in the set (for example, the video controller 38). Section 2 (FIG. 11 (b)) for (int i = 0; i <numberofparity; i ++)} // number of names concatenated with reference to the first comment video name = name + party [i]. name + ','; partythumb = partythumb + party [i]. section 3 // Repeat for the number of people (FIG. 11 (c)) bottomcaption = "+ party [i] .name +" san "that talks about today's enthusiasm; video = party [i] .beginment; section 4 (FIG. 11) (D)) video = party [i] .teeshot; bottomcaption = party [i] .name + "san tee shot"; OK: centercaption = "OK";break; case GREAT: centercaption = "GREAT"; bre ap; {topcaption = “1H” + hole [0] .length + “ydpar” + hole [0] .par; section 5 (FIG. 12 (a)) if (track [i] .type = SHOT) ｛bottomcaption = [I] .shotnumber r + "stroke" track [i] .shottype + "of" + party [track [i] .personsonumber] .name + "'s present" + party [track [i] .personnumberr.

Convert to txt file and record on disk. Section 9 (FIG. 13B) First, a member having the smallest total score is searched. If it is the ith person video = party [i]. endcaption = topcaption = ”, so this time,“; bottomcaption ”value = party [i] .name +“ Sanchi ”; The script executes such an operation, and FIG.
This can be derived from the input information obtained by the input operation described with reference to FIG. 10 and the recorded file of the captured image.

8-6. Processing Operation Next, an example of a processing operation for implementing the editing operation described above will be described with reference to the flowcharts of FIGS. Note that the processing operations shown in FIGS. 13 and 14 are performed by the data processing / system control circuit 31, the driver controller 46, and the camera controller 25 as necessary, for example, after the video controller 38 functions as a master controller. Or signal processing).
This processing is a processing operation executed in an environment in which the editing application program is running.

The processing operation shown in FIG. 14 is performed until a script is generated based on, for example, the guide display shown in FIGS. 8 to 10 and information input (including recording of a captured image) performed in accordance with the guide display. Processing is shown. First,
Assuming that an instruction to operate the guide function display of the editing application program is issued by a predetermined operation performed on the operation unit 7 by the user, the video controller 38 proceeds to step S101, in which the video controller 38 Execute control processing for reading the program. And the following step S
At 102, a process for activating an application program for editing is executed using, for example, a RAM inside the video controller 38.

In the next step S103, reference is made to the exposure control value for the imaging optical system of the video camera device included in the editing application program, and based on this exposure control value, the AE ( Executes control for performing exposure correction for the Automatic Exposure function. In this process, for example, the video controller 38
An instruction is issued to execute control for E correction. The camera controller 25 controls the lens block 1 so that the AE is appropriately corrected based on the exposure control value.

Then, in the next step S104,
According to the started editing application program,
The control process for performing the guide display is started. As a result, thereafter, guide display is performed on the display unit 6A, for example.

Step S105 is an input operation sequentially performed in accordance with an instruction prompted by the guide display, and content (input information) obtained by shooting (recording). Here, the input information is an operation input information and a recording file. ) Is executed. That is, as described with reference to FIGS. 8 to 10, for example, the user performs a necessary input operation or a recording according to input of information prompted for each guide display. This is to execute processing for holding information and a recording file obtained by recording as editing material.
Here, the input information (operation input information) obtained by the operation input is stored in, for example, a RAM inside the video controller 38.
It is assumed that the In addition, a recorded file obtained by shooting is recorded as a file (track) in a directory in a folder of the disc. Then, for example, when it is determined that all the information inputs according to the guide display have been performed (that is, the guide display ends), the process proceeds to step S106.

In step S106, a process for reconstructing the held content according to a script preset as an editing application program is executed. That is, the program contents described in parallel with the description with reference to FIGS. 8 to 10 are set.
Here, it is assumed that the process of step S105 is performed after the end of the guide display. However, for example, in actuality, as the process of step S105, acquisition of content (holding of operation input information and recording of a recorded file) is performed. May be performed each time is performed.

When the processing in step S106 is completed, the video controller 38 proceeds to step S107, and uses the contents of the contents reconstructed as described above to write the script set in advance by the editing application program. The processing for generating the script is executed according to. As a result, for example, a script having the above described contents is obtained.

In the next step S108, control processing for recording the script generated as described above as a script file on the auxiliary data track of the disk is executed, and the processing so far is terminated. To be. By the processing so far, a recording file serving as an editing material and a script file in which a description for designating the editing content is recorded in addition to the editing application program recorded in advance on the disc.

Next, the editing operation using the disc obtained as described above, that is, the processing operation for reproducing the video work based on the recorded file as the editing material will be described with reference to the flowchart of FIG. I do.

For example, if a necessary operation for starting reproduction of a video work is performed on the operation unit, the video controller 38 proceeds to the processing shown in FIG. In the processing shown in FIG.
In step 1, the script recorded on the disk is read. The script to be read here is a script created according to the execution of the editing application program in advance and describing the content for reproducing the video work. The script read from the disk is stored in a predetermined area of the buffer memory 32, for example. Further, if the storage capacity of the RAM inside the video controller 38 is sufficient, it is conceivable that the video controller 38 is configured to store the data in the internal RAM.

In step S202, the interpretation of the script file read from the disk as described above is started, and in the subsequent step S203, a reproduction process according to the description contents of the interpreted script is executed. . In other words, a required recording file (and a file such as an audio track for BGM) required according to the description of the script is read from the disk, and a reproduction process for outputting this as an image / audio is executed. The control for the required functional circuit unit is executed.
At the same time, image signal processing for superimposed display of required characters and symbols corresponding to, for example, <applet> tags and the like, and audio signal processing for BGM output and the like are performed. Execute. By the process of step S203, for example, the reproduction / output mode of the image / audio as the video work shown in FIGS. 11 to 13 is obtained.

Then, as the processing in step S204,
If it is determined that the interpretation of the script has been completed, the processing up to this point is terminated. In other words, the reproduction operation up to this point is terminated in a state where the reproduction of the video work has been completed. Although not shown in this figure, for example, if a stop operation is performed, the reproduction of the video work is terminated at that time, and if a pause operation is performed,
The control process is executed such that the image displayed at the time when the pause operation is being performed is maintained, and the progress of the script interpretation is also paused.

In the above embodiment, the configuration for realizing the editing process for creating the video work corresponding to the golf competition has been described. However, this is merely an example, and the video processing according to other purposes is performed. When creating a work,
It can be realized according to the configuration described so far.

Further, the guide display described in the above embodiment, the manner of giving various editing effects in the state of being finished as a video work, and the like can be appropriately changed according to actual situations.
Further, the language of the script used in the present embodiment is not limited to SMIL, and a configuration adopted by another language may be adopted.

For example, in the above embodiment, FIG.
The editing operation example shown in FIG. 10 to FIG. 10 is merely an example, and other operation modes and other display modes may be adopted as long as the operation mode can be simplified by a general user. . As an example, the display unit 6A is configured to have a function as a touch panel, and an operation similar to that described with reference to FIGS. 8 to 10 is pointed to the display unit 6A using a finger or some pointing device. It is also conceivable to do so.

Further, the video camera of the present embodiment is a disk recording / reproducing device based on MD-DATA2 as a video recording / reproducing portion. However, the video recording / reproducing portion has a configuration other than that of the present embodiment. Alternatively, the recording / reproducing apparatus may be a recording / reproducing apparatus compatible with other types of disc-shaped recording media. Furthermore, in the present embodiment, the description has been made on the assumption that the MPEG2 method is used for compressing moving image data. However, for example, a method capable of compressing and encoding other moving image data may be adopted. Also, the compression method for still image data and audio data need not be particularly limited to those exemplified as the present embodiment (JPEG, ATRAC2, etc.).
