Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a recording medium used for recording motion pictures is a tape-shaped medium and therefore recorded pictures are invariably arranged sequentially on the tape in the recorded order to be necessarily stored by the tape, making it inevitable to be initiated from a head of the tap in the order of time for appreciation thereof. <P>SOLUTION: In order to record motion pictures, not a sequential medium such as a tape but an electronic camera is used which can record on a random- access medium such as a hard disc generating one piece of picture files every recording time of each cut. Then, a large number of the picture files having running times from several seconds to several tens of ones are automatically grouped according to specific conditions such as a recording time range and site or the like so that users reproduce the picture files continuously within the group by the group without having a consciousness of existence of each picture file. <P>COPYRIGHT: (C)2004,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image data management method for an electronic moving image camera which digitally encodes and records a moving image.

[0002]

2. Description of the Related Art In the past, moving images have been widely used from 8 mm movies using an optical film to video cameras using a magnetic recording video tape. In particular, video cameras using VHS-C cassettes and 8 mm video cassettes are very popular for home use.

[0003]

The recording medium used by these moving image photographing cameras is a tape-shaped medium, and the photographed images are always continuously arranged on the tape in the order of photographing. Therefore, the photographed images are always stored in tape units, and when viewed, it is necessary to view them in time order from the beginning of the tape. In order to solve this problem, a method has been developed in which an index signal is applied in the middle of the tape and the index position is fast-forwarded to find the required location. Among these, Victor's <Pocket Digital Movie> DV1 records the captured image as a digital signal on a video tape, and the reproduction operation is performed from a personal computer, so that the reproduction image from a certain time to a certain time of the tape is reproduced. Has been defined as one unit, and a system for reproducing images in an arbitrary order other than the order recorded on the tape has been developed and put on the market. However, since this method also uses a medium called tape, it takes time to display the specified image, and the management of the image on the tape is expressed only by the relative time counted from the beginning of the tape. The management of recorded images was troublesome. It is also possible to save the images of multiple specified units as a series of program-like images with titles, but these operations must be performed after shooting, while viewing the shot images. Was by no means easy.

[0004]

According to the present invention, an image is not a sequential medium such as a tape but can be randomly accessed like a hard disk so that one unit of an image file is generated for each shot. An electronic camera that records on media is used. Then, a large number of image files of several seconds to several tens of seconds generated at the time of shooting are automatically divided into groups according to specific conditions such as a shooting time range and place, and the user is aware of the existence of each image file. It is solved by making it possible to continuously reproduce the image files in the group in units of groups.

BEST MODE FOR CARRYING OUT THE INVENTION A specific example of an embodiment of an image data management method for an electronic video camera according to the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an electronic video camera according to the present invention. In the camera unit 10000, the light 10011 from the subject to be photographed is focused on the sensor 10010 through the lens 10012. Sensor 10010
The virtual image of the subject input to is converted into an electric signal and recorded in the image memory 10030 through the signal processing circuit 10020. In the case of a moving image, these operations are performed, for example, at a speed of 60 frames per second, and the image data stored in the image memory is sequentially converted into compression-encoded moving image data by the compression / expansion circuit 10040. . Compressed moving image data (hereinafter referred to as image data) is stored in the camera 1000.
The data is stored in a PCMCIA card type hard disk drive (HDD) 10200 attached to 0. At this time, the date and time at the time of photographing and the photographing time of the photographed file are read out from the timer 10051 and stored together in the HDD 10200 as auxiliary information of the image data.
The camera controller 10050 controls these operations. The image data stored in the HDD 10200 is
After being decoded again by the compression / expansion circuit 10040 and returned to the image memory again, it is output to the outside of the camera as a video output signal 10031, and the moving image can be viewed on a TV or the like.

For compression-encoded image data, the HDD 10200 is removed from the camera, and the personal computer PC1010
The image data can be transferred to the PC 10100 by inserting it into 0. In addition, the HDD 1020 is connected via the I / F 10060 without replacing the HDD card.
The image data recorded in 0 can be transferred to the PC 10100. Further, without using the HDD 10200, it is also possible to directly compress a captured image using the I / F 10060 while directly compressing it. PC1010
0 on the bus 10111 with the CPU 10110 as the core,
I / F 10120 that connects to the camera 10000,
It is composed of a memory 10130 and a storage medium 10140 for storing image data.

FIG. 2 is an explanatory diagram showing an example of the format of image data photographed and encoded by the electronic video camera according to the present invention. As shown in FIG. 2A, for example, MPEG (Moving Picture), which is a famous moving image compression method, is used.
In the case of "Experts Group", first, I-PICTURE (Intra-PICTU) is added at the beginning of the image file 20000.
There is a still image called RE) 20010 that represents the entire screen. Then, the difference information 20020 in which the image changes in the time axis direction follows. The image length 20030 with these as one unit is a variable length. Basically, by inserting an I-PICTURE in an appropriate time unit designated in advance, the expansion of the error due to the difference is reset, and other than that, If the difference information reduces the efficiency of moving image coding due to extreme image changes (such as camera panning), a new I
-PICTURE is inserted. FIG. 2B shows I-PICT.
URE = I and difference data P-PICTURE (Pre-
It is explanatory drawing which shows the relationship with PICTURE) = P in more detail. The vertical bar on the left side of each I represents a minimum unit break of the moving image data, and I20040 and P20050 are used to interpolate and generate full screen information corresponding to the P frame. Then, using that and P20051, full screen information corresponding to the next P frame is generated. Therefore, the moving image file described in this format is I
-It is possible to divide the PICTURE starting position as a boundary.

FIG. 3 is an explanatory view showing an example of a moving image taken by a conventional video camera using a video tape. Video cameras that use magnetic tape always record captured images in chronological order. Time axis 300
The images 30000 taken are lined up along 50.
In the figure, each square box represents a one-shot photographed image (cut by the photographing button START-STOP unit). This videotape shows an image of a mountaineering trip to Shinshu, and the first five cuts show a set 30010 of images taken on the first day of mountaineering when climbing Happoone. The next 7 cuts show a set 30020 of images taken on the second day of mountain climbing, the next 6 cuts show a set of images 30030 taken when taking a walk around Azumino after descending, and the last 4 cuts are the return trip. 3 shows a set 30040 of images taken during the driving of the. These cuts are arranged sequentially on the magnetic tape as shown in the figure.For example, when you want to see the scene of Azumino walk when the tape is completely rewound, fast forward the tape and skip the Azumino walk. It is necessary to bring the play pointer to the beginning of the set of images. Depending on the video camera,
It is possible to put an index at the head of this set, and by designating, for example, the second index from the head, an image of a walk in Azumino can be viewed. However, in order to see the specific scenes taken, it is necessary to perform operations such as fast-forwarding and rewinding the tape,
This is a problem in viewing a video image taken using a magnetic tape because the operation is complicated and takes time. For this reason, in most cases, the video images taken are always viewed continuously from the beginning to the end.

FIG. 4 is an explanatory diagram showing a recording image on the HDD of image data taken by the electronic video camera according to the present invention. Reference numeral 40000 denotes an internal image of the HDD, and each rectangular frame indicates a cluster that is a unit of read / write access to the HDD data. Figure 3 here
Image data corresponding to the set 30010 in
It is described in five places in D. Specifically, there are five locations from 40020 to 40024, and the HDD
Since the new data is written in the empty area in the HDD, the image data of one set is not always written continuously. However, due to the random accessibility of the HDD, these data can be accessed to any data in basically the same time, and the time is short. The specified image data can be instantly called and viewed in any order.

FIG. 5 is an explanatory view showing a method of managing image data using the electronic video camera according to the present invention. The image data 50000 shows one cut of the image data captured by each square frame, and the order of arrangement in the figure is the same as in FIG. 3, but the substance of each image data is described in the HDD shown in FIG. Therefore, the image data arranged horizontally in this figure can be accessed and reproduced at almost the same time with respect to any of the data.

Here, the first four, the next five, and the next five
The image data set is divided into groups, and the last three groups. This classification is the same as the description of FIG. 3, but since the image data is stored on the HDD here, it is necessary to wait for the fast-forwarding of the tape even when wanting to view the image of the third group, Azumino Walk. There is no such thing, and you can call up and enjoy the images of the group of Azumino walks in an extremely short time.

Further, according to the present invention, a group called Azumino travel digest video 50050 can be defined in addition to a group in which continuous image data are collected. This can be realized by storing the image data in the HDD shown in FIG. 4, but specified ones are selected from a large number of image data in a random order, grouped and defined as one program. It is possible to

FIG. 6 is an explanatory view showing a method of the first embodiment in which the image data is grouped automatically at the time of photographing. A square frame 60000 is each cut of the captured image and is captured in the order of time 60040. The present embodiment has an algorithm that pays attention to the difference in the shooting time of the shots that are shot, and that cuts shot at intervals within a fixed time belong to the same group. For example, if the shooting interval is 30 minutes or more, and if the groups are to belong to different groups, the cut 60011 and the cut 60013 will be displayed in the time interval 600.
Since 12 is within 30 minutes, they belong to the same group, group 1 (60010), but cut 60013
Since the time 60050 between the cuts 60021 exceeds 30 minutes, a new group 2 (60020) is created at the time of photographing the cuts 60021 and the cuts 60021 belong to the group. Similarly, for a cut that has an interval (60060) of 30 minutes or more, a group 3 (60030) is newly established and belongs to that group. By this method, it is possible for the user to automatically perform grouping without classifying images to be taken at the time of shooting.

FIG. 7 is an explanatory view showing a method of the second embodiment in which the grouping of image data is performed automatically at the time of photographing. A square frame 70010 is each cut of the captured image. In the present embodiment, attention is paid to the place where each cut is photographed, and PHS (Personal Handyph
There is an algorithm that cuts taken at almost the same place belong to the same group by using the base station number of "one system". Here, PHS is a system that allows you to use a wireless telephone with less power than an ordinary mobile phone by using base stations installed at intervals of about 300 m. Connect to a base station close to the
Can get Although the system configuration is not shown, for example, in FIG. 1, a PHS is connected to a portable PC such as a sub-notebook and the captured image data is directly transferred to the remote place by the PHS. The base station number may be used, or the PHS may be connected to an electronic camera having a PC function. Here, it is not necessary to represent the current position of the electronic camera by an address or coordinates from the PHS base station number, and it is sufficient to determine that the electronic camera belongs to a specific base station. In this figure, it is assumed that the PHS base station numbers A, B, and C are used for image capturing. The image data shot near the base station number A belongs to the group 1 (70020), and the image data shot near the base station number B belongs to the group 2 (Group 2).
The image data captured in the vicinity of the base station number C is made to belong to the group (70040). Similar to FIG. 6, when a new PHS number is recognized, a new group is created and the captured image data is made to belong to it, so that the image data linked to the location can be automatically divided into groups. . The location may be detected by using a location information detection method such as GPS (Groval Positioning System), but the PHS according to the present invention.
The method using the base station can be used even in an underground shopping center where GPS cannot be received. Here, although the present embodiment has been described as an example of using PHS, the same use can be made in a communication system in which the ID of a base station near the communication device can be known using the wireless communication device. It is possible.

FIG. 8 is an explanatory view showing a method of the third embodiment in which the grouping of image data is performed automatically at the time of photographing. In FIG. 8A, a rectangular frame 80000 is each cut of the captured image, and the time 80
The photographs were taken in the order of 010. In this embodiment, the user has an algorithm in which a user defines a new group at the time of shooting and causes the shots to be shot to belong to a designated group in chronological order. The camera has a switch for designating open-close (OPEN-CLOSE), and a plurality of cuts taken from when the switch is opened to when the switch is closed belong to one group. Specifically, during the first open-close (8
All cuts taken in 0020) are in group 1
All the cuts that belong to (80021) and are taken during the next open-close (80030) belong to Group 2 (80031), and the cuts that are taken during the next open-close (84040) are , All belong to Group 3 (84041). Since the user can switch on, start shooting, and switch off when shooting belonging to the group is finished, it is possible to divide the shots taken into groups, reflecting the user's intention and pre-grouping. It is possible to easily manage captured image data without the complicated procedure of selecting a name. FIG. 8B is an example of a specific shape of the open-close switch. Electronic video camera 80050
There is a switch 80051 next to, which is Open80
The switch is operated by switching to either 060 or Close 80061. Also, if this switch is configured by using the safety cover 80071 of the photographing switch 80070 of the camera, a new group is created when the cover is opened, and some cuts are photographed there. The group can be closed by closing the safety cover when closing the camera for moving. Also, if the main switch of the camera is turned off without closing, the procedure to automatically close the group will be operated, or the group that was previously used will be used when the main switch is turned on next time. Either do the close processing of, or take either method.
Further, the date and time at the time of opening and at the time of closing are recorded as additional information of the group and used as information necessary for selecting the group when accessing the group such as later viewing of images.

FIG. 9 is an explanatory view showing a means for easily grouping cuts already taken. The square frame 90000 is each cut of the captured image,
The photographs were taken in the order of 0010. The present embodiment has an algorithm in which each cut is assigned to a designated group by designating a time range in which the user has photographed. A time stamp is added to each shot taken so that the time when the cut was generated can be referred to at any time. Group 1 is from 9:00 to 11:30
It is a collection of cuts taken up to, Group 2 from 11:30 to 13:50, Group 3 at 13: 5.
It is a collection of cuts taken after 0. This operation is performed after the shooting is finished, and may be performed on the camera, or after transferring to the PC shown in FIG.
You may go on. Further, if the schedule is known in advance even before shooting, it is also possible to define a group in which a time range is specified in advance and have shots automatically belong to the group. Further, the time zone can be specified not only at the start time and the end time but also before or after a certain time.

FIG. 10 is an explanatory view showing a method of randomly selecting designated cuts from a plurality of photographing cuts to generate a group. 100000 is a multi-screen that simultaneously displays all the shots taken. The first I-PICTURE of each cut may be displayed as a still image, or the IP in each cut may be displayed each time the PLAY button is pressed.
It may be a format in which ICTURE is displayed one after another. If the fast forward button and the rewind button are used for this function, the operation of advancing or returning the displayed I-PICTURE is also possible. From each of the cuts displayed in this way, one can be created by selecting the cut that will be the digest. The selection of the cut at this time may be performed by moving the selection frame 100010 displayed on the multi-screen 100000 with a cross-shaped cursor (not shown) or a cursor of left and right arrows installed on the camera and selecting the cut.

FIG. 11 is an explanatory diagram showing a method of selecting a group when reproducing an image. The captured image data is classified into groups, and the user can reproduce the image data in the group by merely selecting the group, and does not need to be aware of the existence of each image data file. Figure 11
(A) shows a method of displaying images in each group on a multi-screen and selecting a designated group from them. On the screen 110000, the first I-PICTURE of the image located at the head of each group is displayed as a still image in the multi-screen of 16 screens in this figure. By moving the selection frame 110010 with a cross cursor key or an arrow key (not shown) and selecting with the selection key, the image data registered in the group can be continuously reproduced. The image displayed on the multi-screen is the first I-
In addition to the PICTURE still image display, use, for example, the cross cursor up / down cursors to display I-of the image files in each group.
It is also possible to show all PICTUREs by frame advance and move the selection frame 110010 with the left and right cursors to select. FIG. 11B shows a method of selecting a group from the date and time of shooting, without depending on the visual recognition of the image. A list of groups is displayed on the screen 110020, and the format is the sequential number of the group, the date 110021 and the time 110022 when the group was created or closed, and the total reproduction time 110023 of the image data contained in the group. : Displayed in seconds. Use the cursor keys (not shown) to select the selection frame 110
By moving 024 and selecting a group with the selection button, the image data in the specified group can be automatically reproduced continuously.

FIG. 12 is an explanatory view showing a concrete method of grouping image files according to the present invention. 12
In (a), the image file is FILE0001. MPG
(120,000), FILE0002. MPG (120
010), FILE0121. MPG (120020)
, 121 files are prepared, and what is shown in the figure is an attribute data image of each file. The shooting date, the shooting start time, the length of the file in hours, and other information are attached to the file name.
These pieces of information are added to the image data entity and stored in the HDD. FIG. 12B shows data defining a group, which itself may be a file.
It may be data included in the camera program itself. FILE000 for Group 1 (120030)
2. MPG, FILE0014. MPG, FILE00
07. MPG, and FILE0002. MPG belongs to this data and each address 1200
40 is described. The image files indicated by this address may be changed in order or may be duplicated. Further, the address may directly point to a physical address in the HDD, or may be in the form of instructing by a file name according to the information for managing the file system of the HDD. In this case, the data in the group need only be the relative address and file name from the location of the group in the area where the data exists.

FIG. 13 is an explanatory diagram showing a method of dividing an image file and grouping using the divided files. For example, an MPEG format image file can be divided in units of I-PICTURE as shown in FIG. Here, by dividing one captured image file into smaller scenes in units of I-PICTU and handling them as independent files,
A finer grouping is possible. The original image file FILE0100. MPG (130000) is

It is divided into G (130030) files. The shooting date, time, length, and original file name of each file are described as its attribute data. I
-By dividing the image file in units of PICTURE, the actual image is a regular I-PICTURE.
In addition to the I-PIC that comes in after doing extreme bread
Since division by TURE can be performed, it is possible to remove a scene where the camera is extremely swung in the captured image and use it for group generation, and in fact, the same effect as editing work can be obtained. The group generated using these files is the group 1 (1300 in FIG. 13B).
40). The contents are the same as those in FIG. 12B, and a detailed description will be omitted. Here, in the case of copying a group of captured images to show to another person, when the group 1 is copied, the image body (130050) belonging to the group 1 is automatically copied together. Only the image file body defined in group 1 is contained in it, and it is not the original image data before division. Since only the minimum necessary image data is passed during copying, it is possible to save capacity and protect confidentiality.

FIG. 14 is an explanatory view showing a method of consolidating a plurality of image files, and a method of cutting out a part of the image files and performing grouping, contrary to FIG. The image data normally projected in FIG. 14A has FILE0001. MPG (140000), FILE
