Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an editing apparatus and an editing method for editing, for example, images and sounds.
Further, the present invention relates to a recording / reproducing apparatus capable of performing the above-described editing. In addition, the present invention relates to a storage medium storing a program for editing an image and a sound.

[0002]

2. Description of the Related Art In recent years, video cameras in which an image pickup device such as a camera and a recording / reproducing device such as a video deck are integrated have become widespread.

In such a video camera, for example, various kinds of editing can be performed on image data recorded on a recording medium.
As one of such edits, voice information such as narration and music is additionally recorded in an image already recorded on the recording medium in synchronization with the reproduction time. What is called after-recording (hereinafter, also simply referred to as "after-recording") is known. This is often used in editing for so-called electronic albums.

[0004] Such dubbing is usually performed, for example, as follows. First, a user who performs editing pre-records audio data as audio material for post-recording. Then, the user reproduces the audio data for post-recording while reproducing the image data as the editing source already recorded by the video camera. At this time, while watching an image to be reproduced, adjustment is performed so that audio data for after-recording that can be heard as reproduction sound is inserted at a desired timing. Then, the image data and the audio data thus reproduced are combined using a so-called dubbing technique to create a new track (file). This new track becomes the post-record edited track.

[0005]

However, the above-described apparatus for performing post-record editing does not currently have a user interface for visually recognizing the reproduction time timing of images and sounds. For this reason, it is almost necessary to rely on the intuition of the user in synchronizing the reproduction time of the image and the sound, so that the dubbing editing work is very troublesome.

In addition, in the case of the above-described editing method, in order to create a new track on which post-record editing has been performed, in terms of signal processing, the original image and sound as a material must be copied ( Dubbing) and recording it again on a recording medium. In other words, the editing track is created by the image and audio data copied from the source material. Therefore, the newly edited track has a data size corresponding to the image and audio data copied from the copy source material, so that the recording capacity of the recording medium is reduced accordingly. . Such a problem becomes a problem particularly when, for example, the recording capacity of the recording medium is not so large.

[0007]

Embodiments of the present invention will be described below. As the editing device and the recording / reproducing device of the present embodiment, a portable video camera in which a camera device unit and a recording / reproducing device unit capable of recording / reproducing images (still images or moving images) and audio are integrated. Take the case where it is installed as an example. The recording / reproducing device mounted on the video camera according to the present embodiment is a so-called mini-disc (MD: Mini Disc) which is known as a type of magneto-optical disc.
And a configuration for recording and reproducing data. 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 Script 8. Operation screen display 9. Post-record editing 9-1. Operation procedure 9-2. Program configuration 9-3. Processing operation

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 the 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, a land Ld is a recording track (a track on which data is recorded).
Since the wobbled groove WG and the non-wobbled groove NWG are formed as described above, the track Tr is also used as the recording track.
-The two tracks A, Tr and B are independent of each other,
It will be 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 a distance between the centers of the adjacent tracks Tr.A and Tr.B, and the track pitch is 0.95 μm as shown in FIG. 2B.

Here, the wobble formed in the groove as the wobbled groove WG is formed based on a signal in which a 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. Also, regarding 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 as described above 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 where 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, the MD-DATA2 format which can be supported by the video camera of this embodiment has a track pitch of 0.95 μm and a pit length of 0.39 μm / b.
It can be seen that both are shorter than the MD-DATA1 format. For example, in order to realize the above pit length, the laser wavelength λ = 650 nm, the aperture ratio NA of the optical head is set to 0.52, and the beam spot diameter at the in-focus position is reduced, and the band as the optical system is expanded. .

As described with reference to FIGS. 1 and 2, a land recording system is adopted as a recording system, and an interlace addressing system is adopted as an address system. 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 and reproduction 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.

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 section 3, the image signal 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.

The MPEG2 video signal processing circuit 33 performs compression processing on the input image signal data in accordance with the MPEG2 format while using, for example, the memory 34 as a work area, and generates a bit stream (MPEG2) of compressed data as a moving image. 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 configured to generate 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 by VBR, for example, the motion detection circuit 35 performs motion detection in the range of several tens to 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 determined 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 via the inside. 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 from the disk 51 and decoded in accordance with the MD-DATA2 format by the processing of the MD-DATA2 encoder / decoder 41 (in the media drive unit 4) Data processing / system control circuit 31
Will be transmitted. 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, 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.

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 composed of the lens block 1 and the camera block 2 as a matter of course. It is possible to display and output almost in real time. In addition to the reproduced image and the captured image, as described above, a message display using characters, characters, or the like 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.

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

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 it 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

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.

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.

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.

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 CLV processor 111 receives the clock CLK from the equalizer / PLL circuit 104 and the groove information GFM via the ADIP band pass 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.

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 that has been processed up to this point is read from the buffer memory 42 and transmitted to the RL via the data bus 114.

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 irradiation timing of a laser pulse. 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, it is possible to make the jitter of the recording pit extremely small. That is, the laser strobe magnetic field modulation method is a recording method advantageous for high-density recording.

The magnetic head drive circuit 119 of the media drive unit 4 operates so that a magnetic field modulated by 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, an example of a data structure of the disk 51 according to the present embodiment will be described. First, data units called sectors and clusters will be described as the format of MD-DATA2. A sector is a minimum unit for physically reading data from a disk.
An SA (Physical Sector Address) is assigned. The cluster is a minimum unit of physical data writing to the disk, and is formed by a set of 16 consecutive sectors having a PSA of 0h to Fh. Each cluster is assigned a PCA (Physical Cluster Address). A sector in a lead-in area (pre-mastered area) described later can be uniquely specified by the PCA. Further, as for the clusters in the recordable area, the clusters having the same PCA exist for each of the tracks Tr.A and Tr.B.

FIG. 9 conceptually shows an example of a data management form of the disk 51 according 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 are set as management information. PTOC is
Required management information is recorded in a pit form. This P
The contents of the TOC cannot be rewritten. RTOC
For example, basic information necessary for managing data recorded on a disc is recorded. For example, in the case of this example, as data recorded on the disk, tracks (sometimes synonymous with files) and folders (structures for managing tracks by grouping them) are used for recording and reproducing. Information is stored. Note that RT
The contents of the OC are sequentially rewritten in accordance with, for example, the results of data recording on the disk and the results of editing processing such as deletion of tracks (files) and folders.

The user data is managed as a volume folder (Volume Folder) located in one root folder. In the present embodiment, the 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, a volume index track (VIT: Volume Index Track) of a predetermined size (for example, 12 clusters) is placed. This volume index track is, for example, the PT
If the OC and RTOC are the main management information, they are defined as areas in which the sub-management information is recorded.
Data) has a table in which information for managing properties, titles, and packet data forming a track is recorded.

Also, as a track managed in the volume folder, a thumbnail track (Thumbnail Pictu
re Track) can be placed as an option.
In the present embodiment, one still image with 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 a correspondence with a file (track) recorded on the disc and a 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. FIG. 9 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, a folder has a structure for managing tracks or folders in one 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. Although detailed description is omitted here, the image data (Imag
e) is also stored.

By the way, the PTO which is the management information is
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,
The data 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).

FIG. 10 shows the data management form shown in FIG. 9 corresponding to the physical structure of the disk 51. The lead-in area shown in this figure is a pit area on the innermost circumference of the disc, in which PTOC information is recorded.

A recordable area is formed around the lead-in area via a transition area. This recordable area is a magneto-optical recording area where magneto-optical recording and reproduction can be performed. In the recordable area, as described above with reference to FIGS. 1 and 2, two tracks, ie, the tracks Tr.A and Tr.B, are formed on a double spiral.

In the innermost circumference of the recordable area,
An RTOC area is provided for each of the tracks Tr.A and Tr.B. Then, in the RTOC area of the track Tr · A, information of the RTOC having a size of four clusters is repeatedly recorded three times. And following this, 12
A cluster size volume index track is arranged. Following the volume index track, a thumbnail track can be arranged as an option. It is defined that at least the first cluster is located as a thumbnail track in the RTOC area. Then, for example, when the number of thumbnail image data increases as the number of files increases and exceeds the capacity of the thumbnail track in the RTOC area, it is possible to additionally record in a recordable data area described later. . At this time, the thumbnail track on the recordable data area is managed by a volume index track (or RTOC).

Following the thumbnail track in the RTOC area, an area for recording script and image data as auxiliary data can be set as an option. Further, when the script and image data exceed the recordable capacity in the RTOC area, they are additionally recorded in the recordable data area in a form managed by the volume index track (or RTOC). You can go.

Then, a recordable data area is provided from the address position indicated by the recordable data area start address W. AV data, ie, track (file) data, is recorded in this recordable data area. The thumbnail image data and auxiliary data described above can also be recorded.

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

The above description relates to the track Tr · A. However, as can be seen from FIG. 10, the area setting of the track Tr · B is similar to that of the track Tr · A.
However, the RTOC area is undefined at this stage. That is, the RTOC area includes the track Tr
Only A is used substantially.

Note that the example of the disk structure shown in FIGS. 9 and 10 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. The structure in which the data is stored can be changed.

6. Thumbnail Image Generation Processing The thumbnail images stored in the thumbnail tracks shown in FIGS. 9 and 10 can be generated by the video camera of the present embodiment. Let me explain. Here, a case where a thumbnail image of an image file already 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 disk and accessing the address to execute a read operation on the disk, 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
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 (number of pixels) enough to be displayed in a substantially full size on the display screen. 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 with respect to the 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. 9) 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 (for example, 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. 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 presentations 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 is <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
<Seq><video src = “video 1”><video src = “video 2”><video src = “video 3”></seq> or <seq><play video 1 ><Playvideo2><playvideo3></seq>

Also, the file video1 → video
2 → video3 and video1
For audio1 which is a file of audio data
<Seq><par><video src = “video1”><audio src = “audio1”></par><video src = “video2”><video src = ”video3” The description will be performed as in "></seq>.

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 an image file of video1 is displayed (reproduced), <par><video src = “video1”><image src = "Scratch1" begi
n = “5s”></par> The description is made as follows.

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”>.

[0125] 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 ">.

In order 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 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
Interpretation and script description (generation) corresponding to MIL
, 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, for example, in the editing stage (or the stage of performing a recording operation). It is to be kept in the area. Then, the script held in the buffer memory 32 in this manner is recorded on a disk at a predetermined opportunity or timing. The data of this script is shown in FIG. 9 and FIG.
Auxiliary Data Trac described in
k) is stored as a script file. By recording the script on the disc in this way, the next time the disc is newly loaded, the script recorded on the disc 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. Display of Operation Screen In the video camera of the present embodiment, an operation screen is displayed on the display panel 67 when searching for a file recorded on the disc and performing various editing and setting processes. As this operation screen, various kinds of information about the currently loaded disc and files recorded on the disc are presented. Then, various operations for a certain purpose are realized by using a pressing operation on the operation screen (hereinafter referred to as a pointing operation) and an operation on various operating elements in combination.
Here, as the operation screen of the present embodiment, a so-called thumbnail display for presenting a corresponding thumbnail image (small image) for each file recorded on the currently loaded disc is also performed. That is, the user can visually confirm the contents of the file (track) recorded on the disc by viewing the thumbnail image displayed on the operation screen. Further, a file search, reproduction, and the like can be performed by operating the thumbnail image.

FIG. 11 shows an example of a display form of an operation screen displayed on the display panel 67 of the video camera according to the present embodiment. This operation screen is displayed as an initial screen when, for example, a reproduction / edit mode is set in a state where a disc is loaded.

In this figure, first, an information display area A1 is provided in the upper part of the display area. In the information display area A1, various types of information required by the user are presented. Here, the remaining battery level display area A1-1, the sports mode display area A1
-2, a reproduction mode display area A1-3, a remaining recording time display area A1-4, and a disc icon A1-5.

In the remaining battery level display area A1-1, the remaining battery level is indicated by a battery symbol and time. Although detailed description is omitted here, in the video camera of the present embodiment, as a playback mode, for example, a sport mode in which a user can confirm the movement of a motion of a subject or the like photographed by performing frame-by-frame playback or the like is performed. It can be set. In the sport mode display area A1-2, when the sport mode is set, for example, as shown in the figure, the character "SPORT" notifies that the sport mode is currently set. In the reproduction mode display area A1-3, various special reproduction modes such as shuffle reproduction, repeat reproduction, and reproduction between A and B are presented by characters, symbols, and the like. The remaining recording time display area A1-4 indicates the remaining recordable capacity of the disc by time. The disc icon A1-5 displays, for example, that a disc is loaded, and when a pointing operation is performed on the disc icon A1-5, various information on the currently loaded disc is displayed from the operation screen shown in FIG. Is displayed,
It is possible to switch to the display of the disc information screen.

Below this information display area A1, a thumbnail display area A2 is provided. Here, up to 9
It is possible to display thumbnail images (for nine files), and here, a state is shown in which thumbnail images SN of A to I are displayed. Although not shown here, for example, actually, as each thumbnail image SN,
For example, if the file is a recorded file, an image extracted from the recorded file is displayed as a still image.

Here, the arrangement order of the thumbnail images SN in alphabetical order of A to I basically follows the reproduction order. That is, in the present embodiment, the thumbnail images can be displayed in a predetermined arrangement order according to the file reproduction order specified by the script. However, if an operation such as sorting is performed, thumbnails are displayed according to the sort order.

In this case, the number of thumbnail images that can be displayed at one time is nine. For example, when the number of tracks (files) recorded on the disc is more than nine, and thus the number of thumbnail images is also more than nine, Is performed by pointing and performing, for example, a drag operation on a scroll bar A4 displayed on the right side of the thumbnail display area A2 to scroll the thumbnail images displayed in the thumbnail display area A2 or switch pages. It can be displayed while being displayed.

[0136] Various icons are superimposed on each thumbnail image SN displayed in the thumbnail display area A2. As these icons, the moving image icon i1 indicates that the file corresponding to the thumbnail image on which the icon is superimposed is a file in which a moving image is recorded. In the case of FIG. 11, it is recognized that the thumbnail images (A, B, C, D, E) are moving image files.

The icon displayed on the thumbnail image (G) is a still image icon i2, which indicates that the file is a still image file. What is displayed on the thumbnail image (H) is the interview file icon i3, which indicates that it is an interview file recorded in the above-described interview mode. Also, the group icon i4 is displayed on the thumbnail image (I). In the video camera according to the present embodiment, as a management on the thumbnail display, a plurality of files that are continuous in the order of reproduction are grouped together and displayed as one thumbnail image. can do. The group icon i4 is thus superimposed on the thumbnail image corresponding to the grouping.

The icon displayed on the thumbnail image (F) is a memo file icon i5. In the video camera according to the present embodiment, as an editing function, the content that the user has written down can be created as one independent file. If such a memo file is inserted and reproduced, for example, before an arbitrary file, the title-like content of the file can be displayed by the memo file. The memo file icon i5 indicates that the file is a memo file.

Further, for example, the icon imitating a pencil displayed on the thumbnail image (C, E) is a graffiti icon i6. As an editing function of the video camera of the present embodiment, the user can use the pen 320 or the like to perform an operation trajectory on the panel display unit 67 or paste a stamp image or the like on an image file that has already been recorded.
It is possible to add a graffiti-like image.
The graffiti icon i6 indicates that the file has been scribbled by the scribble function.

A mark icon i7 is displayed on the thumbnail images (B, E). The user can add a mark to an arbitrary file by an operation described later. For example, the user is made to mark a file that is important to him as a reminder. The mark icon i7 indicates that the mark is attached.

A lock icon i8 is displayed on the thumbnail images (A, E). The user can also set “lock” so as not to change or delete any file by performing an operation described later. The lock icon i8 indicates that the file is locked. An effect icon i9 is displayed below the thumbnail images (A, E). In the present embodiment, it is possible to give a special reproduction effect such as various scene changes or mosaics to the file.
Indicates that the file has such a special effect.

In this embodiment, various icons are superimposed and displayed on the thumbnail image in this manner, so that various attributes such as the type of file corresponding to the thumbnail image and various setting conditions can be provided to the user. It is possible to make them visually recognized.

The pointer icon i10 displayed so as to frame the image of the thumbnail image (E) is displayed when the user performs a pointing operation on the thumbnail image with the pen 320 or the like. It is moved and displayed with respect to the image. Then, the thumbnail image in which the pointer icon i10 is arranged and displayed is currently selected. Here, for example, if the user operates the playback / pause key 308, the playback is started from the track on which the pointer icon i10 is arranged and selected.

A menu key area A3 for displaying various menu keys is provided on the left side of the thumbnail display area A2. In this menu key area A3,
In order from the top, a reproduction menu key A3-1, an edit menu key A3-2, a graffiti / effect menu key A3-3, a studio menu key A3-4, and a setting menu key A3-
5. The advanced menu key A3-6 is arranged and displayed.

The reproduction menu key A3-1 is a key for presenting a menu relating to various types of reproduction and setting the reproduction mode. For example, a reproduction mode reflected in the reproduction mode display area A1-3 can be set. The edit menu key A3-2 presents various items related to editing in recorded file units. For example, a track (file) is moved, copied, deleted, track divided, a file is grouped, and a still image is taken out ( For example, selection of a still image to be displayed as a thumbnail image) can be performed. Also,
Here, an operation for displaying the track information and performing a transition to a track information screen on which various settings for each track information can be performed can also be performed.

The graffiti / effect menu key A3-3 is used to set a graffiti function and various special reproduction effects such as scene change (fade-in, fade-out, wipe, etc.), audio special effects, and image special effects (mosaic, sepia processing). Is presented. Further, the video camera of the present embodiment has a function of easily creating a video work by recording and operating the user according to the GUI. Studio menu key A3-4
Presents a menu corresponding to such a simplified video work creation function.

The setting menu key A3-5 is a menu for making various settings such as the brightness of the screen as the display unit 6A, the shade of the panel color, the brightness of the viewfinder, the date and time setting, and the still image setting time. Be presented. The advanced menu key A3-6 presents a menu relating to, for example, a connection function with a personal computer and a demo mode.

A track information display area A5 is provided below the display area. In the track information display area A5, information about the track corresponding to the thumbnail image selected (where the pointer icon i10 is located) in the thumbnail display area A2 is displayed. Here, first, the track number is shown in the track number display area A5-1, and subsequently,
In the date / time / title display area A5-2, the recording date / time and the title assigned to the track are alternately displayed every predetermined time (for example, several seconds). The total time of the track is displayed in the time display area A5-3. Further, the shortcut icons A5-4 correspond to the various icons described above (for example, the moving image icon i1, the still image icon i
2. One of the interview file icon i3, the group icon i4, and the memo file icon i5) is displayed. And this shortcut icon A5-4
When a pointing operation is performed on the track information screen, it is possible to move to a track information screen.

In the thumbnail display area A2, between each of the thumbnail images SN arranged in the horizontal direction, as shown in the figure, an order indication sign icon i11 in which the vertices of the triangle are directed rightward. Is displayed. This is because, for example, after the reproduction of the recorded file corresponding to the thumbnail image SN located on the left side of the order indication sign icon i11 is completed, the thumbnail image S located on the right side thereof is displayed.
N is reproduced. As mentioned above,
In the thumbnail display area A2, the arrangement order of the thumbnail images SN in alphabetical order of A to I is in accordance with the reproduction order (chronological order), but the order indication sign icon i11 is displayed as described above. Thus, the order can be more visually grasped on the thumbnail display area A2.

Here, as an operation example of the menu key area A3, the case of the reproduction menu key A3-1 will be described as an example with reference to FIG. For example, as shown in FIG. 12, when a pointing operation is performed on the reproduction menu key A3-1 with, for example, the pen 320, a first pop-up menu is displayed. First
In this case, the pop-up menu contains "← back",
Menu items of “sport analysis mode”, “play mode”, and “sort” are displayed. When the first pop-up menu is displayed, for example, when the jog dial 303 is rotated (or may be dragged on the screen with a pen or the like), the selected item is moved according to the rotation direction. It is going to go. Then, for example, as shown in the figure, "play mode"
Is selected and the jog dial 303 is pressed (or a pointing operation with a pen for a certain period of time or more may be performed) to display a second pop-up menu.

Here, the second pop-up menu includes
Four items of “normal”, “disk repeat”, “shuffle”, and “intro scan” are displayed. Then, the user can select and determine a desired item from these items by performing the same operation as the above-described operation on the first pop-up menu on the second pop-up menu. The play mode set in this way is reflected, for example, as the display content of the playback mode display area shown in FIG.

9. Post-record editing 9-1. Operation Procedure Next, post-record editing of the present embodiment will be described. The post-record editing here refers to editing in which audio data is added (recorded) later in association with the image data already recorded on the disc and synchronized with the reproduction time of the image data. is there. In general, voices that are audio data added by post-record editing include, for example, narration and so-called BGM.

An example of an operation procedure for performing post-record editing in the video camera according to the present embodiment will be described with reference to FIGS. FIGS. 13 to 16 show examples of display modes on the display panel 67 according to operations performed by the user.

When the user performs some editing, the user operates the main dial 300 to set the playback / edit mode. In the case of the reproduction / edit mode, FIG.
The initial screen is shown as shown in FIG. This screen is, for example, the same screen as that shown in FIGS. 11 and 12. In the following description, this initial screen will be referred to as an "index screen".
It is distinguished from other types of screens that are displayed according to subsequent operations.

When performing post-record editing, a pointing operation is performed on the graffiti / effect menu key A3-3 displayed on the screen shown in FIG. Is done. When such a pointing operation with the pen 320, that is, a pressing operation, is performed, the touch panel 6A provided on the display panel 67 detects the pressed position, and for example, the data processing / system control circuit 31 displays the currently displayed image. By identifying the correspondence with the detected pressing position, it is possible to determine what the instruction corresponding to the pointing operation by the pen 320 is. For example, in the above case, it is determined that an operation for presenting a menu has been performed from the graffiti / effect menu key A3-3. In addition, all the operations described below, including the above-described operations, can be performed by the jog dial 303, which will be described later.

When the pointing operation is performed on the graffiti / effect menu key A3-3 as described above, the setting of the graffiti effect or the special effect is performed as shown in FIG. Is displayed. Since the pop-up menu PUM1 in this case includes “after-recording” indicating post-record editing as an editing item, the user can
For example, the editing item of this “after-recording” is selected and designated by a pointing operation or the like. This causes the display panel 67 to transition to the screen shown in FIG. 14A, which is the initial setting screen for post-record editing. FIG. 14A will be described later.

FIG. 13 (a) → FIG. 13 (b) → FIG.
The operation shown as (a) shows a proper operation procedure, but in the present embodiment, a so-called shortcut operation procedure is used to perform the post-record editing on the index screen shown in FIG. To an operation screen for In the post-record editing of the present embodiment, as described later, in order to specify a range of image data to be post-record edited, a thumbnail image of a file serving as a starting point and a thumbnail image of a file serving as an end point are used. Is required to be specified.

For example, if the thumbnail image (A) in the thumbnail images SN displayed in FIG. 13A is a file serving as a starting point of the post-record editing, the user can select the thumbnail image ( For example, a long-pressing pointing operation is performed on A). Then, in this case, as shown in FIG. 13B, it is attached to the thumbnail image (A),
Pop-up menu PUM that presents various editing items
2 is displayed. Then, the user performs an operation of selecting and specifying the item of “after-recording” from the items presented in the pop-up menu PUM2,
It is possible to specify post-record editing. In this case, the screen shown in FIG.
The screen shifts to the screen of (b).

In other words, if the original operation procedure is proper, the process proceeds as shown in FIG. 13 (a) → FIG. 13 (b) → FIG. 14 (a). FIG. 13 (a) → FIG. 13 (c) → FIG.
It can be advanced as in (b). That is,
An operation procedure corresponding to FIG. 14A can be omitted. As a result, depending on the operation shown in FIG. 13C, it is possible to simultaneously select post-record editing for the editing item and specify the starting point of the range of image data to be edited (post-recording range). You are doing it.

When the operation described with reference to FIG. 13 (a) → FIG. 13 (b) is performed, the screen shifts to the operation screen shown in FIG. 14 (a). Here, FIGS. 14 (a), (b), and (c)
Is a “dubbing range setting screen” for performing an operation of setting a dubbing range for image data to be edited. In FIG. 14A, an operation screen for designating a recording file to be a starting point as a post-recording range is provided, as indicated by "Please select a starting point" for the track information display area A5.

The screen shown in FIG. 14A is initially displayed as an operation screen only for post-record editing, and an operation screen specialized for some kind of editing is thus displayed. When displaying, in this embodiment, for example, the operation stage display 600 is arranged and displayed on the right end side of the information display area A1. As shown in the figure, the operation stage display 600 in this post-record editing includes, for example, three stage marks 601, 60 indicated by a circle.
2, 603 are arranged and displayed in the horizontal direction. Here, the number of stage marks indicates the approximate number of steps for editing. In other words, with regard to post-record editing, the presence of three stage marks indicates that a total of three steps are required. When a plurality of stage marks are displayed, the order of the stages is indicated in the direction from left to right. These stage marks (601, 602, 603) can be switched in two display modes, non-highlighted display and highlighted display.
When highlighted, it indicates that the procedure has already been completed or that the procedure is currently at that stage. Regarding post-record editing, the first step is to set the post-record range, and FIG. 14A shows a screen for setting the post-record range. Therefore, in FIG. 603)
The leftmost stage mark 601 corresponding to the first procedure is highlighted (shown in black in the figure), and the remaining stage marks 602 and 603 are not highlighted. It should be noted that FIG.
14C, the screen for setting the post-recording range is the same as that in FIG. 14A. It is similar.

A stop button BT1 is arranged and displayed in the track information display area A5 of the screens of FIGS. 14A and 14B and 14C described below. When the click operation is performed on the stop button BT1, the screen is returned from the post-recording range setting screen to the index screen, and the post-record editing is also canceled. Note that the cancellation of post-record editing by operating the stop button BT1 is the same in the case of FIGS. 15 and 16 described below.

The following operation can be performed on the screen for setting the starting point of the after-recording range shown in FIG. Here, it is assumed that the user wants to select the recording file A as the starting point of the after-recording range. In this case, the user performs a pointing operation on the thumbnail image SN of the recording file A. Then, the screen is switched to the display shown in FIG. In FIG. 14B, a display indicating that the recording file A is specified as the starting file is displayed. That is, by highlighting the periphery of the thumbnail image SN of the recorded file A by the selection display frame 701, it is indicated that the recorded file A is within the designated post-recording range. Further, for example, as shown in the figure, a starting mark 702 indicating that the recorded file is the starting point is added and displayed. When the recording file A is selected as the starting point in this way, the actual starting point is the reproduction start position of the recording file A. As described above, FIG.
In the case of the operation procedure from 3 (a) to FIG. 13 (c), since the recording file A as a starting point is also specified at the operation stage shown in FIG. 13 (c), this operation is directly performed. The screen shifts to the screen of FIG.

In the screen shown in FIG. 14 (c), the recording information file to be the end point is specified as the post-recording range, as in the case of "Please select end point" for the track information display area A5. Is prompted. Here, it is assumed that the user wants to select the recording file E as the end point of the after-recording range. In this case, the user intends to designate the entire post-recording range from the recording file A, the recording file B → the recording file C → the recording file D, and finally to the reproduction end position of the recording file E. Will be. Therefore, in this case, the user may select the thumbnail image S of the recording file E.
By performing a pointing operation on N, the recording file E is designated as the end point. Then, the display screen is switched to the one shown in FIG.

On the display screen shown in FIG. 14 (c), the post-recording range is displayed so that the post-recording range can be visually recognized in response to the start and end points of the post-recording range being designated by the operation so far. . That is, recording files A, B,
As shown in the drawing, a selection display frame 701 is additionally displayed for each of the recording files A, B, C, D, and E in correspondence with the recording ranges of C, D, and E. And
An end point mark 703 indicating an end point file is additionally displayed for the thumbnail image SN corresponding to the recorded file E which is the end point file. By performing such a display, the user can visually confirm the post-recording range designated by the user, and can also select the display frame 701, the start mark 702, and the end mark 7 as described above.
With the display of 03 or the like, the visual confirmation is very easy to understand. Further, in accordance with the designation of the after-recording range in this manner, the total of the reproduction times of the entire after-recording range is indicated as "total time" in the track information display area A5. Here, as a specific example, it is indicated that the total time of the recording files A, B, C, D, and E is “12:04 (12 minutes and 4 seconds)”.

Then, the user checks the dubbing range by looking at the display shown in FIG. 14 (c), and if he is satisfied with this, the [Next] button displayed in the track information display area A5 A click operation is performed on BT2. As a result, the display panel 67 is displayed as shown in FIG.
The screen is switched to the screen display shown in (a), and the operation proceeds to the next stage. Here, if an operation is performed on the stop button BT1, for example, as described above, FIG.
The screen is returned to the index screen shown in (a), and the previous editing operation can be performed again by the above-described procedure.

By the way, according to the above description, in the present embodiment, first, after specifying an edit item,
The procedure of specifying the edit target is performed. That is, in the case of FIG. 13 and FIG. 14, first, post-record editing is specified as an editing target, and subsequently, a GUI screen for post-record editing is displayed, and a GUI screen for this display screen is displayed. By the operation, an operation for designating an editing target, that is, an after-recording range is performed.

For example, with respect to the selection of the edit item and the specification of the edit target, the edit target is specified in advance, contrary to the above case, and thereafter, what kind of editing is performed on the specified edit target It is also conceivable to perform an operation of designating an editing item for determining whether the item is to be edited. A typical example of such a procedure is an operation such as copying or deleting in a personal computer or the like. That is, the user first specifies a range (designation of an edit target) for a character string or the like. After that, if an operation for executing the copy (designating an edit item) is performed, the character string whose range is specified is copied. Alternatively, if an operation for executing deletion is performed, the character string whose range is specified is deleted.

However, when such an operation is applied to an editing function such as the video camera of the present embodiment, which is a consumer device, there is a greater degree of freedom in specifying an editing target. Conversely, it may be inconvenient to perform the intended editing. For example, if the specification of the editing target performed by the user is incompatible with the editing intended by the user, the operation of specifying the next editing item is invalidated. In such a case, a general user who usually handles only consumer devices will feel uncomfortable with the operation. On the other hand, according to the operation procedure as in the present embodiment, the editing item is first specified, so that the next GUI image to be displayed includes an editing target suitable for the specified editing item. It is possible to limit the operation to the designation operation. For example, as shown in FIG.
The user can easily be prompted to perform the operation of specifying the after-recording range while displaying a message or the like.
That is, operability is improved.

FIGS. 15 (a), 15 (b) and 15 (c) show image data in the after-recording range designated as described above.
This is a “recording screen” corresponding to a case where an editing operation is performed in which audio data as post-record audio is recorded in association with it. However, as will be understood from the following description, the term “recording” does not necessarily mean that audio is actually recorded as audio data. For example, audio recording of audio data already recorded on a disc Editing for associating a file with the playback time of a moving image is also included. The operation procedures for recording corresponding to FIGS. 15A, 15B, and 15C are shown in FIGS. 14A, 14B, and 14C.
This is the second stage following the post-recording range setting shown in FIG.
Therefore, the operation stage display 600 includes the stage mark 6
Of the 01, 602, and 603, the highlighting proceeds to the two stage marks 601 and 602 from the left.

FIG. 15 (a) shows an initial display state as a recording screen.
For example, a display area as the image display area 605 is provided. The image display area 605 is an area for displaying a reproduced image of the recorded file set as the post-recording range. In the initial state, for example, the first image of the recording file A specified as the post-recording range is in a stationary state. It is assumed to be displayed.

A time information display area 606 is provided on the right side, where both the recording time and the remaining time are to be displayed. The recording time and the remaining time are configured to change with the lapse of time due to the progress of the after-recording sound recording described below.

Further, below the image display area 605 and the time information display area 606, the progress display area 6
07 is provided. In the progress display area 607, a progress bar 608 is provided as described later so as to show the progress of audio data to be added as a post-record sound.
Is displayed.

In this case, a comment "Please record" is displayed in the track information display area A5, so that the user is urged to record the post-record sound. Then, the user is prepared to record the post-recording sound. In the case of the present embodiment, two modes are conceivable as preparations for recording a post-recording voice. One is to prepare for taking in and acquiring voice or audio data from the outside, for example. Here, as a method of acquiring external voice or audio data, for example, there is a method of inputting voice using a microphone 202 of a video camera. There is also a method in which the audio data is acquired by transferring the audio data from another device capable of outputting the audio data via the external interface 8. As another mode, for example, an audio data file already recorded on the disk 51 is designated as the after-recording sound. Although not shown in the operating procedure so far, in the present embodiment, audio data recorded on the disk 51 can be designated as audio to be added to image data by post-record editing. ing.

As described above, the user operates the record button BT3 after preparing for recording after-recording sound. As a result, the display is switched from that shown in FIG. 15A to the display shown in FIG.

When the post-recording is started, thereafter, as shown in FIG. 15B, the image display area 605 displays the recording files A to E designated as the post-recording range.
Will be displayed according to the actual playback time. In addition, as the moving image displayed at this time, a frame image may be displayed according to a specified frame period. For example, frame images sampled at regular intervals may be sequentially displayed and output. Good. When the images are displayed at a constant sampling interval in this manner, although the smoothness of the motion as the reproduced moving image is impaired, the image display area 605 is intended to visually grasp the progress of the reproduced image. Does not cause any problem, and the processing load for displaying a moving image in the image display area 605 can be reduced.

[0177] Further, the display is performed so that the recording time in the time information display area 606 increases as the time during which the post-recording proceeds progresses, and the remaining time decreases as the recording time progresses. Will be done. Furthermore, in the progress display area 607, the progress bar 608 is displayed so as to extend from left to right in accordance with the lapse of the time of post-recording. For the track information display area A5,
A comment "Recording" is displayed to indicate that recording is currently in progress.

If a click operation is performed on the stop button BT4 while recording is being performed as shown in FIG. 15B, the post-recording is stopped at that point.

Then, when the reproduction of the recorded files A to E as the post-recording range is completed, the display state of the recorded screen as shown in FIG. 15C is obtained. That is, for example, in the image display area 605,
The last frame image of the last recorded file E in the after-recording range is displayed. The time information display area 60
As the recording time in No. 6, the time corresponding to the total reproduction time of the post-recording range is displayed, and conversely, the remaining time is displayed as 0 minutes and 0 seconds. At this time, a comment "Recording completed" is displayed in the track information display area A5. And
At this stage, the setting for the synchronous reproduction of the audio data as the post-recording sound with respect to the reproduction time of the image data in the post-recording range has been completed internally according to the result of the current recording. When the stop button BT4 (FIG. 15B) is operated during recording, the image display area 605, the time information display area 606, and the progress display area displayed at the time of the operation are operated. While keeping the state of 607, FIG.
A recording end screen corresponding to (c) is displayed.

With such a recording screen display method, the user measures the timing of inputting the after-recording sound while watching the progress of the reproduced image displayed in the image display area 605, and performs recording. It becomes possible. Particularly in the case of the present embodiment, the progress display area 60
By displaying the progress bar 608 for 7, it is possible to display the time progress up to the present as a ratio to the total playback time as the after-recording range.

Then, for example, when the user displays a recording end screen as shown in FIG.
When the “next” button is operated, the screen is switched to the screen shown in FIG.

The screen shown in FIG. 16A is a "preview screen". When the screen shifts from the recording screen shown in FIG. 15 to this preview screen, the next operation procedure is executed. Mark 60
In addition to 1,602, the stage mark 603 on the rightmost side corresponding to the last procedure is also highlighted. Then, on this preview screen, the result of post-recording performed as described with reference to FIG. 15 is output. In other words, the recording files A to E in the after-recording range are displayed on the display panel 67 in a substantially full size, for example, during a normal playback time. Along with this, the recorded after-recording sound is output from, for example, the speaker 205 at a timing according to the result of the previous recording. By listening to the progress of the image in the post-recording range displayed on the preview screen and the post-recording audio output from the speaker 205 at the same time, the user can edit the recording result of the post-recording audio as intended. It is possible to check whether or not is done. Then, as can be seen from the operation procedures so far, calling the preview screen is a very simple operation without any particularly complicated operation or work.

It should be noted that the image /
Playback of sound is performed by the stop button BT1 and the "back" button BT
5 and the execution button BT6 are repeatedly repeated until an operation is performed. Here, for example, if the result of the after-recording confirmed by the preview has failed and you want to redo the after-recording again,
What is necessary is just to operate the "return" button BT5. By operating the "return" button BT5, the screen returns to the initial recording screen shown in FIG. 15A, and the post-recording can be performed again. On the other hand, if the result of the after-recording confirmed by the preview is successful and the current preview result is to be saved as a post-record file, the execute button BT6 is operated. If the stop button BT1 is operated, the post-record editing is canceled and the screen returns to the index screen (FIG. 13A).

When an operation is performed on the execution button BT6, a new post-record file (track) assumed to have been created by the post-record editing is performed inside the video camera.
Create The process of creating a new file corresponding to post-record editing will be described later. Then, as the display screen, from the preview screen shown in FIG.
The screen shifts to the index screen shown in FIG. At this time, on the index screen, a thumbnail image SN corresponding to the new post-record file I corresponding to the current post-record editing is displayed as shown in the figure. Here, the newly obtained post-record file I is treated as the last file in the reproduction order.
As shown in the figure, the thumbnail image SN corresponding to the recording file H which was the last file before the post-record editing was performed.
Is displayed at the next position.

The operations shown in FIGS. 13 to 16 can be performed by an operation involving pointing on the display panel 67 with the pen 320 or the like. However, in the present embodiment, the rotation by the jog dial 303 is performed. All operations on the display panel 67 can be performed by a combination of the operation and the pressing operation. For example, in the case of the operation for the post-recording screen shown in FIG. 14, by rotating the jog dial 303, the click between the thumbnail image in the thumbnail display area and each button key in the track information display area A5 is performed every click. With the cursor (pointer icon i1
0) can be moved. Then, after a cursor is placed on a desired thumbnail image SN or a button key and a selection is made, and a pressing operation on the jog dial 303 corresponding to the determination operation is performed, for example, a file is specified, and a clicking operation on the button key is performed. Is what was done. If the editing operation can be performed by the jog dial 303 in this manner, the jog dial 303 can be used efficiently, and the user can operate the jog dial 303 with only one operation element using the pen 320 or the like. Since the same operation as the operation can be performed on the GUI, the convenience is improved. In addition, when the pen 320 is not at hand, or when one hand is blocked and the like and the pen 320 or the like cannot be operated, the same operation can be performed by using the jog dial 303. Also,
For example, the present embodiment also has an advantage that it can be operated with only one hand holding the video camera of the embodiment.

9-2. Program Configuration Hereinafter, processing operations and the like executed inside the video camera to realize the post-record editing described above will be described. First, FIG.
A program configuration for realizing the post-record editing described in FIG. 6 will be described. FIG. 17 conceptually shows the structure of a GUI program applicable to the present embodiment. Generally, as is well known, a GUI program is converted into an object language that can be executed in advance by a compiler and a linker, and stored in a storage medium. For example, in the case of a computer device, it is stored in a storage medium such as a hard disk. In the following description, the term "program" is used to refer to an executable program. And the GUI
When a program is executed, its data is read from a storage medium, written and stored in a memory such as a RAM capable of high-speed processing, and a CPU (Central Processing Unit) refers to the data to execute information processing and various controls. And a so-called GUI image is displayed on the display device.

FIG. 17 schematically shows the general structure of such a GUI program. The explanation here is
For convenience of giving generality, it is assumed that the computer is operated on a computer device, for example. As shown in this figure, the GUI program 400 is functionally composed of functional blocks of an application 401, a display operation block 402, a dialog manager 403, a device handler 404, and a graphic device interface (GDI) 405. Can be seen as a thing.
The physical device 406 is actually a memory, for example, and is a work area for generating image data as an image (application image) according to an application to be displayed on the display device.

The GDI 405 associates the GUI program 400 which is a so-called logical device, the logical device, and a memory area where the logical device is recorded. Here, the logic device generates so-called image components, such as a button image, a scroll bar, a window frame, and an image input from a video camera or the like, necessary for generating the application image on the display device. It is a program necessary to display. In addition, the logical device may be associated with an actual device constituting a computer device such as a mouse, for example, as a correspondence with a memory area. For example, a button image is displayed on a screen. Sometimes, there is no actual button. The logical device in such a case is called a virtual device.

The application image is formed as bitmap data on the video memory (physical device 406) via the GDI 405 by designating the logical device and its positional relationship. It is generated on the screen of the device, and as a result, is displayed as a display image.

The external operator 407 is, for example, an operating means such as a mouse and a keyboard in the case of a computer device. For example, when an image of a logical device displayed on a display device such as a button is clicked with a mouse, an event occurs. Here, since the address on the video memory is associated with the coordinate position on the screen of the display device,
Which button was clicked is GDI405
Can be detected via the. Such detection is executed by the device handler 404. That is, the device handler 404 detects what logical device is specified by the external operation device 407, and acquires the relevant logical device. Upon acquiring the logical device, the device handler 404 starts communicating with the interaction manager 404.

The interaction manager 404 interacts with the application program 401 about what the logical device has been acquired (input event) and what it means. Here, the application 401
It is created according to the purpose of use of the I program, and the procedure to be executed for the application image displayed on the display device and the input event from the external operator 407 is determined in detail. When the application 401 and the dialog manager 403 determine the configuration of the response application image to the input event, the application 401 notifies the display operation program 402 of the result.

The display calculation program 402 is provided with a function of calculating and determining the display method of the response application image. For example, among the image elements generated before the event input, those which have not changed are not changed. The position of the image element whose position has been changed is specified by calculation, and if a new logical device is needed, the new logical device is read from the memory area where it is recorded, and the application of the response image is stored on the video memory described above. It instructs the GDI 405 to form an image. Although the GUI program has been briefly described above, the elements constituting the above-described GUI program are collectively called objects, and possess respective identifiers.
A class corresponding to a class written in a software description language corresponds to this object (also referred to as an instance).

Next, a description will be given of a configuration example of a GUI program which is configured by applying the basic structure of the above-described GUI program to the video camera of the present embodiment. Here, for convenience of explanation, only the configuration of the GUI program necessary for post-record editing will be described.

Here, in describing the structure of the GUI program for post-record editing, a schematic diagram of FIG. 18 will be referred to. This figure shows a functional portion for realizing a GUI for post-record editing as an internal configuration of the video controller 38 which is a master controller in the video camera of the present embodiment. Here, a CPU 38a, a ROM 38b, and a work RAM 38c are shown. The CPU 38a
Based on various programs stored in the ROM 38b, necessary control processing is appropriately performed. ROM38b
Is constituted by a nonvolatile memory element such as a flash memory.
Stores various programs to be executed. The contents of the program will be described later as necessary. The work RAM 38c includes a CPU 38a
Is used as a work area, and required data is appropriately held.

The CPU 38a reads out the basic system control program 501 stored in the ROM 38b, stores it in the work RAM 31b, and refers to the program to execute basic system functions such as storage area management. Various processing operations can be realized.

A GUI application program 510 is stored in the ROM 38b.
The I application program 510 includes a page image generation task 511, a reproduction order indicator display task 512, a page image selection / marker display task 513, an after-recording audio selection / after-recording progress display task 514, a selected frame reproduction task 515, and the like. Is done.

The CPU 3 responds to the post-record editing operation.
Various controls to be executed by 8a (including display control)
Recording system control program 50 for realizing
2 is stored. Further, a GUI program 503 for achieving the basic functions of the GUI in the video camera of the present embodiment is stored.

Here, for example, the image displayed in the image display area 605 in the recording screen of FIG.
The image displayed on the preview screen shown in FIG. 9A is obtained by skipping frame image data at regular intervals from the original moving image data and reproducing and outputting the image data at the same reproduction speed as the original image data. It is assumed that For example, for each file, the image data for display at the time of post-record editing is collected by thinning the frame image data as described above, and is referred to as a page image here. Then, by referring to the page image generation task 511, the CPU 38a extracts frame images at regular intervals from the original image data of the file recorded on the disk as described above, for example. To generate page image data for one file. Then, for example, the plurality of page image data generated in this way is stored in a free storage area in the buffer memory 32 as a page image database.

By referring to the reproduction order indicator display task 512, a triangle order indicator icon i11 indicating the file playback order shown in FIG. 11 is displayed in the thumbnail display area A2. CPU3
FIG. 14B shows a state 8a by referring to the page image selection / marker display task 513 during post-record editing.
A selection display frame 701, a start point mark 702, and an end point mark 703 are displayed as shown in FIG.

Further, the CPU 38a refers to the post-recording voice selection / post-recording progress display task 514 and, for example, as described above, the source selected as the post-recording voice material (for example, from the microphone 202 or an external interface, from the outside). The input audio data or audio data recorded on the disc is selected) and loaded into the buffer memory 32, and a control process is performed to output the post-recording audio via the speaker 205. In this case, the audio data for after-recording may be taken into the buffer memory 32 to form the after-recording audio database. At the same time, the CPU 38a also executes control for displaying the progress of the readout amount of the post-recording audio data as a progress bar 608 (see FIG. 13) to indicate the progress of the post-recording. For image display, for example, a predetermined area of the buffer memory 32 is used as a video memory, and bitmap data of an image to be displayed on the display panel 67 is formed in the area as the video memory.

The CPU 38a executes the display in the image display area 605 in the recording screen of FIG. 15 by referring to the selected frame display task 515. That is,
A page image corresponding to the image data specified as the post-recording range is read out from the buffer memory 32, and is read at the same speed as the reproduction speed of the original image data so that the image is displayed as the image display area 605. I do.

The CPU 38a refers to the post-recording system control program 502 to execute control according to an event that has occurred during post-record editing.
That is, the display screen and the processing operation mode are switched when a button such as turning on, stopping, next, and returning the operation stage indicator is clicked. Particularly, for example, when the after-recording is OK, the execution button BT shown in FIG.
When a click operation is performed on No. 6, a process for newly creating a post-recording track is executed.

9-3. Processing Operation Next, based on the above description, a processing operation according to the editing operation including the post-record editing processing of the present embodiment will be described with reference to FIGS. The processing shown in these figures is performed, for example, by the video controller 38.
Function as a master controller, and the data processing / system control circuit 31 and the like execute control processing as necessary. In addition, in the processing flow described below, if necessary, FIG.
The necessary programs stored in the ROM 38b shown in FIG.

First, the video controller 38 operates as shown in FIG.
In step S101 shown in FIG. 7, the process waits for an operation to specify an edit item. Then, when it is determined that the editing item designation operation has been performed, the process proceeds to step S102. In step S <b> 102, display control is performed so that the display of the GUI screen according to the designated edit item is performed on the display panel 67. Here, for example, when it is assumed that an operation that designates post-record editing as an editing item has been performed as described with reference to FIG. 13, the post-record range setting screen shown in FIG. 14A or FIG. Is displayed. As described above, in the present embodiment, the editing item is specified first, and the editing target is specified thereafter. Therefore, the GUI screen after the editing item is specified has The display is such that the selection of the edit target according to the designated edit item is appropriately performed. The processing from step S101 to S102 is a control processing for this.

After the GUI screen corresponding to the specified editing item is displayed in step S102, the user
On the GUI screen, an operation to specify an edit target to be performed according to the specified edit item is performed. For example, in the case of post-record editing, an operation for setting a post-recording range is performed on the thumbnail display, and, for example, in the case of file division, a file to be divided is specified. is there. Then, step S1
In step 03, the process waits for the above-described editing target designation operation to be performed, and if such an operation has been performed, the process proceeds to step S104.

In step S104, it is determined whether or not the edit target is appropriate. For example, depending on the edit item, there may be cases where the designation of the edit target is not suitable for the edit item, or may be meaningless. For example, in the case of post-record editing, there is a case where a file before the previously specified starting file is selected as the end point file. If such an operation has been performed, the process proceeds to step S105, in which the operation is invalid, and a warning display that prompts, for example, a retry is executed. Then, again, step S
The process returns to step 103. This allows the user to redo the operation of specifying the edit target. On the other hand, if the editing target performed by the user is appropriate, the process proceeds to step S106.

[0207] In step S106, a display for indicating the editing target specified by the operation so far is performed. For example, in the case of the post-record editing, the confirmation display of the post-record range by the selection display frame 701, the start mark 702, the end mark 703, and the like as shown in FIG.

In the following step S107, the process waits for the start of an operation for actual editing of the editing target specified as described above. For example, in the case of file division editing, this is the first operation for setting the division position in the file specified as the editing target. FIG.
This is an operation for shifting to the recording screen shown in FIG.

Then, in the next step S108, an editing process to be executed after the editing start operation determined in step S107 is executed. Also in this case, for example, in the case of file division editing, operations such as setting and changing the division position in a file designated as an editing target are performed.
(A) → (b) → (c), necessary control processing for realizing the after-recording operation is performed.

Here, as the editing processing in step S108, a processing operation to be actually executed in response to post-record editing will be described with reference to a flowchart of FIG. Here, first, in step S201, the recording screen shown in FIG. 15 is displayed as the GUI screen. At this time, playback and display of the file specified as the after-recording range in the image display area 605 are performed. At this time, as described above, as image data to be reproduced and output in the image display area 605,
When using the page image created by the page image creation task 511 shown in FIG. 18, the page image created for the image data specified as the post-recording range is stored in the buffer memory 32, and the buffer memory 32 The display image data is generated so that the page image read out from is reproduced in the image display area 605 according to the same reproduction time axis as the original image data. Further, the progress bar 608 in the progress display area 607 is also displayed so as to be changed according to the progress of reading the audio data that is the after-recording audio. The display is performed while changing according to the progress.

On the post-recording screen, for example, audio data obtained by picking up sound by the microphone 202, audio data input via the external interface 8, or audio data recorded on a disc is used as post-recording audio. However, in the next step S202, the audio data input in this way is also loaded into, for example, the buffer memory 32. Although the processing operation is not shown, when audio data is input, the audio data is transmitted to the speaker 20.
5 is also used to execute a control process for outputting the voice. The processing from step S201 to S202 is continued in step S203 until it is determined that the recording is completed or stopped. While this processing is continued, for example, FIG.
The recording screen is displayed as described in (b). Then, for example, it is determined that the recording state has been completed with the display state shown in FIG.
Alternatively, when it is determined that the stop button BT4 is operated to stop, the process proceeds to step S204.

In step S204, a script for post-recording is generated in accordance with the result of the recording process performed in steps S201 → S202. That is, a script is generated for the image data in the designated after-recording range, which is described so that the audio data as the after-recording sound can be reproduced and output in synchronization with the reproduction time. Then, in the next step S205, the script created in this way is written and held in the buffer memory 32. In this way, when the processing corresponding to the after-recording is performed as the processing of step S108, at the end of the processing of step S108, at least the audio data input along with the execution of the post-recording and The script created as described above is held in the buffer memory 32. When the above-described page image is used for reproducing the image data in the image display area 605, this page image is also stored in the buffer memory 32.

The description returns to FIG. The editing process in step S108 is continued until it is determined in the next step S109 that the editing process has been completed. For example, it is determined that the editing has been completed by, for example, elapse of a predetermined time or an operation corresponding to the completion instruction. If so, the process proceeds to step S110 in FIG.

In step S110 in FIG. 20, the operation waits for an operation for instructing the confirmation reproduction, and if it is determined that the operation for instructing the confirmation reproduction is performed, the process proceeds to step S111. Let me go. The confirmation reproduction here is, for example, in the case of file division or the like, based on the designation of the division position performed in the previous step S108, in order to allow the user to confirm whether the designated division position is acceptable. Repeat playback of a position. In the case of post-record editing, preview reproduction is performed on the preview screen shown in FIG.

[0215] In step S111, control processing for confirmation reproduction is executed in response to the confirmation reproduction instruction operation. Here, for example, in the case of the preview of post-record editing shown in FIG. 16A, the script stored in the buffer memory 32 is read, and the reproduction control is executed according to the content of the script. At this time, if a page screen is held in the buffer memory 32, for example, the page screen is read out from the buffer memory 32 and reproduced and output.
The audio data, which is the after-recorded voice read out from, is read out at a necessary timing and reproduced and output in accordance with the description content of the script. As a result, FIG.
As described in the operation of the preview screen in FIG. 6A, the audio data as the post-record audio is reproduced and output as the audio in synchronization with the reproduction image in the post-record range. In the present embodiment, in the post-record editing preview, data temporarily stored in the buffer memory 32 is read out and reproduced and output as described above. For example, reading data from the buffer memory 32 is faster than reading data from a disk, so that the processing load and the like can be reduced.

Then, the process in step S111 is
The process can be repeated until it is determined in step S112 that an execution (decision) operation has been performed, or it is determined in step S113 that an operation for reediting has been performed. If this is made to correspond to post-record editing, as described with reference to FIG. 16A, the operation of repeating preview playback until the execution button BT6 or the “return (re-edit)” button BT5 is operated, This is realized by the above processing.

Here, if it is determined in step S112 that the execution (decision) operation has been performed, the process shifts to a process corresponding to the editing decision after step S114. When an operation for instructing re-editing is performed in step S113, the process returns to step S107 in FIG. Thus, it is possible to start over from the editing operation on the editing target again.

In step S114, a required editing confirmation process corresponding to the currently specified editing item is executed. Then, as an example of this editing confirmation processing, processing corresponding to post-record editing in the present embodiment is as shown in FIG. In FIG. 22, for example, first, in step S301, a script created corresponding to the current post-record editing result is read from the buffer memory 32, and is read out from an auxiliary data track (Auxiliary
Data Track: See FIG. 9 and FIG. 10). Then, in the subsequent step S302, the audio data as the after-recording audio which is also stored in the buffer memory 32 is read out, and this is recorded as, for example, one file. In other words, here, as the editing confirmation processing, processing for recording and saving data (script, audio data) serving as a material for post-record editing, which is held in the buffer memory 32, to a disk. .

The editing confirmation processing of FIG. 20 is continued, for example, in step S115 until it is determined that the processing has been completed. If the processing has been completed, the flow advances to step S116. In step S116,
For example, the management information (R) recorded on the disc is such that the data recorded on the disc by the editing confirmation processing in step S114 is properly managed on the disc.
Update of TOC and VIT (Volume Index Track). For example, in the case of post-record editing, the script is recorded on the disc as a result of the editing confirmation processing, and if audio data was input at the time of recording, this audio data is also newly recorded Become. Therefore, by associating these scripts with the audio data and the recorded files that have already been recorded and to be edited, the management information is updated so that a new post-record file is managed as being formed. To be. At this time, information such as a recording position on the disk such as a script newly recorded this time is also written in the management information.

In the following step S117, a new index screen is displayed based on the contents of the management information updated as described above. For example,
In the case of post-record editing, a thumbnail image SN corresponding to a new post-record track created by the current post-record editing is generated and displayed as in the index screen shown in FIG. It is to let.

Although the processing is not shown in the flow charts shown in FIGS. 19 to 22, if an operation for canceling the editing is performed, the result of the editing processing so far is cleared. The display on the display panel 67 returns to the index screen which is the initial display. For example, in the case shown in FIG. 14 to FIG. 16, the operation is performed on the stop button BT <b> 1.

Although the operation relating to the editing processing according to the present embodiment described above is applied to a video camera, the processing therefor can be performed by software. Is performed by software, for example, in general, it can be realized by a general computer. In such a case, a program constituting the software is installed in a computer or the like.

FIG. 23 shows a configuration example of a computer in which a program for executing the above-described series of processing is installed. The program is stored in a hard disk 705 or a ROM as a recording medium built in the computer.

[0230]

As described above, according to the present invention, as a procedure for various kinds of editing using a thumbnail display (display on a small screen) as a GUI, first, an instruction for an edit item is detected, and then the instruction is given. An instruction operation such as an instruction to be edited performed on a thumbnail image corresponding to an edit item is detected. In this configuration, since the edit item is specified first, the GUI for specifying the next thumbnail image can be adapted to the specified edit item. This has the effect that the operability of is improved.

[0231] In addition, as for the operation for making the above-mentioned designation, for example, a so-called jog dial or the like can be operated with a rotary operation element. In the case of adopting such a form, for example, the same operation can be realized by a rotary operation device attached to the device without using a separate operation means such as a mouse or a pen, which is very useful.

Further, according to the present invention, the number of steps (operation step display) of the editing procedure to be executed in accordance with the specified editing item is displayed and output. The user
By looking at the display indicating the number of steps, the necessary number of steps can be grasped. Also, when displaying the number of steps of the procedure as a display, if a display (stage mark) is made so that the progress of the steps of the procedure can be visually recognized, the user can see this display. ,
The progress of editing up to the present can be easily grasped.

In the present invention, when the editing process involves data input within a certain limited time, as in the case of data recording during post-record editing, for example, In the above, a time progress display (display by a progress bar) is made to visually recognize the lapse of time. As a result, the ratio of relying on intuition and the like as a user's editing operation is significantly reduced. For example, even a general user who is not particularly skilled in editing work can easily perform editing as intended. Is possible.

Further, according to the present invention, when a plurality of editing items are presented in a display mode such as a pop-up menu, for example, the display order in the pop-up menu is determined according to the frequency of instructions or the like. The priority of the edit item is changed. With such a GUI, the editing items frequently used by the user are displayed in such a manner that a higher priority is given to the editing items, so that the operability at the time of instructing the selection of the editing items is improved. become.

When a thumbnail image for displaying a plurality of thumbnail images (small images) is displayed and output, a marker (for example, a reproduction order) indicating the time-series order of data corresponding to these thumbnail images (for example, the reproduction order). Order indication sign icon), which makes it possible to grasp the playback order at a glance by the order indication sign icon rather than, for example, simply displaying the thumbnail images in an array. Become.

As described above, according to the present invention, the operability and the visibility are improved as the GUI screen for the editing operation, so that a more user-friendly function can be provided than before. Things.

In addition, the present invention relates to a method of combining original data stored in a storage medium and additional data to be reproduced and output in synchronization with the reproduction time of the original data, such as post-record editing. When performing additional data editing for creating new data, reproduction control information (script) having description contents for realizing post-recording reproduction is generated according to the editing result. Then, for example, additional data typified by, for example, after-recording audio, and playback control information are stored in a storage medium. On this storage medium, the additional data, the playback control information,
For example, it is managed as new edited data (for example, a new post-record file) by associating it with original data such as image data. With such a configuration, for example, the newly edited file is composed of the original data already stored in the storage medium, the additional data, and the reproduction control information for synchronously reproducing them. What is newly stored in the storage medium is substantially only the reproduction control information and the additional data. Therefore, the data capacity that increases in accordance with the creation of a new edited file can be significantly reduced as compared with the case where data consisting of copied original data and additional data is newly created as new edited data as in the related art. That is, the storage capacity of the storage medium can be significantly reduced. As described above, the present invention generally provides the user with more convenience and usefulness when editing is performed.
