  As shown in FIG. 1, the system according to the present embodiment includes a recording device 1 that creates a recording medium 9 and a data management device 10 that uses the recording medium 9. The recording device 1 includes smart media and compact flash. (Registered Trademark), Memory Stick (Registered Trademark), SD Memory Card, Multimedia Card, etc., Media Loading Unit 2 for Loading Recording Medium (hereinafter referred to as Media 8), Digital Camera 7 (Digital Still Camera and Digital Movie Camera) And image data and the like are downloaded from the server 16 via a communication network 15 such as the device connection unit 3 for connecting a photographing device such as a mobile phone 7a with a camera or the like by wire, wireless or infrared. Input control means such as network connection unit, media 8 and digital camera CD-R / RW or DVD ± R / RW in which image data read from 7 or downloaded from the server 16 or image data converted into a format reproducible by a DVD player, DVD recorder, game machine or the like is recorded, A recording medium loading unit 4 for loading a recording medium 9 such as a DVD-RAM or a Blu-ray disc, an operation unit 6 such as a button, a keyboard, or a mouse, and a display unit 5 such as an LCD or CRT (displayed as the operation unit 6 in the figure). The touch panel which combines the part 5 is shown.).

  Further, the data management device 10 includes at least a recording medium loading unit 14 for loading the recording medium 9 and a recording unit such as a hard disk 11 for storing image data. The means of the data management apparatus 10 is shown in a block diagram as shown in FIG. That is, the input control means 17 for reading image data and identification information from the recording medium 9 loaded in the recording medium loading unit 14 for loading the recording medium 9, the identification information of the loaded recording medium 9, and the image data already stored. The identification information comparing means 18 that compares the identification information of the recording medium that has been stored and registered in the database, and the data structure of the image data recorded on the loaded recording medium 9 (if necessary) Data structure comparison means 19 for comparing the type and quantity of image data of each type and the data structure of the already stored image data, and recording the image data in the recording means such as the hard disk 11 and the database Recording control means 20 for registering information, display means 12 such as a monitor, and operation means 13 such as a keyboard and a mouse.

  Note that each of the above units may be configured as hardware in the data management apparatus 10, or a computer is configured as a management program that causes at least the identification information comparison unit 18 and the recording control unit 20 to function. It may be configured to be installed in the data management apparatus 10 and executed. 1 shows a case where a personal computer is used as the data management apparatus 10, the form of the data management apparatus 10 is also arbitrary. For example, a dedicated set-top box as shown in FIG. As shown in FIG. 4, a portable writer, as shown in FIG. 4 as an HDD recorder, DVD recorder or game machine equipped with arithmetic processing means, as shown in FIG. 5, as a car navigation device equipped with arithmetic processing means, etc. You can also.

  Next, a procedure for creating the recording medium 9 using the recording apparatus 1 having the above configuration will be described with reference to the flowchart of FIG.

  First, in step S101, the media 8 is loaded into the media loading unit 2 of the recording apparatus 1, the digital camera 7 or the camera-equipped mobile phone 7a is connected to the device connection unit 3, or the network connection unit is connected to the communication network 15. At the same time, the recording medium 9 is loaded into the recording medium loading unit 4. The recording medium 9 may be a recording medium in which no data is recorded, or the user may purchase a recording medium in which other programs such as a management program and a slide show program, and music data are recorded in advance. . Next, in step S102, the image data recorded on the digital camera 7 or the medium 8 (still image data, moving image data, data including image information, etc. are collectively referred to as image data) or the server 16 is recorded. The image data is read, and image data to be recorded on the recording medium 9 is selected using the display unit 5 and the operation unit 6 as necessary.

  Next, in step S103, music data to be used as BGM for reproducing the image data as a slide show with music is read from the media 8, the server 16, the storage unit of the recording apparatus 1, and the like as necessary. Note that the music data may be selected by the user, or music data set as a default in advance may be used.

  Next, in step S104, reduced image data such as thumbnail image data or screen nail image data obtained by reducing the data size of the read image data is created as necessary. The reduced image data only needs to have a data size smaller than the input image data. For example, the reduced image data may be image data with a reduced number of pixels, color data, or image data with a reduced color reproduction range.

  Next, in step S105, if necessary, the read image data can be read by a video player (Video-CD format, DVD-Video format, DVD player, DVD recorder, HDD recorder, game machine, etc.). HDTV format data). The method for creating the moving image data from the image data is not particularly limited. For example, when still image data is displayed like a slide show, data with a difference 0 corresponding to the slide display time is added to the still image data. The moving image data may be generated by generating moving image data or adding difference data based on the slide effect set by the slide show program to the still image data.

  Next, the input image data, the generated reduced image data, and the converted moving image data are recorded on the recording medium 9. At this time, the data can be recorded on any recording medium 9. Alternatively, data recording may be permitted only to the recording medium 9 that is normally created. In the latter case, for example, in step S106, with reference to position information (for example, physical address) stored in advance in the storage unit, it is determined whether or not specific identification information is written in advance in the position. Data recording can be started only when the identification information is written.

  In that case, since the identification information is provided to prevent unauthorized data recording, if the recording location and contents of the identification information are easily known, the identification information itself is also copied and the unauthorized data In other words, at least part of the identification information cannot be accessed by the OS of the computer (that is, outside the logical address area), specifically inside the logical address area of the disk type recording medium. It is preferable that data is written in this area.

  Here, the structure of a general recording medium 9 will be described with reference to FIG. 15. The CD-R is formed on a polycarbonate substrate 100 with an organic dye layer 101 such as cyanine, phthalocyanine, or azo and a reflective layer such as silver. 102 and an overcoat layer 103 are laminated to form a pit by applying a laser beam of a predetermined power to the organic dye layer 101 to decompose the dye and deform the substrate to record information. However, since the optimum value of the laser power differs depending on the type of the laser head that irradiates the laser beam and the type of the organic dye layer 101 used, the CD-R is necessary for reliably writing and reading information. It is necessary for the drive side to recognize what kind of pigment is used to manufacture the disk. Therefore, information such as the type of dye used for the CD-R and the name of the manufacturer that produces the CD-R is written in the innermost circumference at the manufacturing stage of the recording medium 9, and the information is read by the drive firmware. The laser power is adjusted by controlling the laser head. As described above, the innermost area of the disc is used as an area for recording information on the features of the CD-R, and is usually an area that cannot be accessed by the OS. By writing the identification information of the recording medium 9, it is possible to prevent the identification information itself from being copied.

  The specific configuration of the identification information is arbitrary, but since the manufacturer's name is recorded in advance outside the logical address area of the recording medium 9 as described above, the manufacturer's name and the recording medium 9 are recorded. By using the number assigned to the identification information as identification information, it can be easily and reliably identified whether or not the recording medium 9 is properly created.

  The data is recorded on the recording medium 9 in which the identification information is written. However, since the recording area where the data can be read is limited in the image reproducing device, the converted moving image data, the association file, etc. in step S107. (Hereinafter collectively referred to as an image reproduction device data group) is transferred to a predetermined folder for writing, and then the image reproduction device data group is read out from the folder and stored in the recording medium 9. Record inside the logical address area. Thereafter, in step S108, before recording the data for the computer device, the session is temporarily closed in order to classify the data area usable in the image reproduction device.

  In step S109, image data and an application such as a slide show program, a setting file, an information file, music data, and the like (hereinafter collectively referred to as a computer device data group) are provided in advance. After transferring to a predetermined folder for writing, the computer device data group is read from the folder and recorded outside the data group for image reproduction device previously recorded on the recording medium 9 to complete the series of writing processes. To do.

  Various types of information are recorded on the recording medium 9 created in the above procedure as shown in FIG. 14, and outside the innermost logical address area of the disk type recording medium 9, a predetermined format (preferably a file) Non-format data format) identification information is recorded, a data group for image reproduction equipment is recorded inside the logical address area outside it, if necessary, and a computer equipment data group containing image data outside that Is recorded.

  Further, the recording structure of the recording medium 9 created by the above procedure is as shown in FIG. 9, for example, and the computer equipment data group includes image data, thumbnail image data, screen nail image data in the “PS_Roll” folder. A plurality of types of image data (image data group), an information file (info.txt) in which various information related to the recording medium 9 is recorded, a slide show program in the “APPL” folder, a slide show setting file, an automatic startup file It is composed of other data groups such as (Autorun.inf), and the image playback device data group associates the image data in the “VCD” folder as data for Video-CD format, DVD-Video format, HDTV format, etc. Files, image data to be displayed on the TV screen in the “SEGMENT” folder, video data in the “MPEGAV” folder, It consists of an application for displaying still image data on the TV screen in the “DAT” folder. Further, in the information file (info.txt), for example, the identification information of the recording medium 9 (which may be the same as or different from the identification information recorded outside the logical address area of the recording medium 9) or recording The title of the medium 9, shooting date / time information, the number of image data groups (rolls) recorded in the recording medium 9, identification information (roll ID) of each image data group, and the like are recorded.

  Although the recording structure of the image data group is arbitrary, in order to facilitate management when the image data group is backed up to the data management apparatus 10 or the like, a folder is configured according to a predetermined rule, and the folder is stored in the folder. It is preferable to give a unique name. For example, as shown in FIG. 9, a folder (ROYYMMDDyyy_XXXXXXAABxxx, here RO030416001_12345601C001) indicating the storage location of image data for each medium 8, device, and film in the lower hierarchy of the folder (PS_Roll) indicating the storage location of image data YYMMDD: Number that identifies the date of writing, yyy: Sequential number for each day, XXXXXX: Random ID number, AA: Manufacturer code (00 to ZZ), B: Software, device Product category (0 to Z), xxx: Sequential number can also be used.

  Next, a procedure for saving the image data group recorded on the recording medium 9 created by the recording device 1 in an area (here, the hard disk 11 of the data management device 10) that is saved and managed by the management program is shown in FIG. This will be described with reference to the flowchart of FIG.

  First, in step S201, the recording medium 9 is loaded into the recording medium loading unit 14 of the data management apparatus 10. In step S202, the identification information comparison unit 18 reads the information file from the recording medium 9 loaded in the recording medium loading unit 14, and the identification information (album ID) of the recording medium 9 described in the information file. And identifying identification information of a registered recording medium on which image data has already been stored, by referring to a database recorded in advance on the hard disk 11 or the like, and identifying information on the loaded recording medium 9 And the identification information of the registered recording medium are compared.

  Next, if the identification information is different in step S203, it is determined that the image data recorded on the recording medium 9 is not stored in the hard disk 11, and the input control means 17 is used in step S204. Then, all types of image data are read out from the recording medium 9, and in step S205, a file check is performed such as whether the read image data file is damaged. Then, in step S206, the recording control means 20 is used. The image data is recorded in a recording destination such as the hard disk 11.

  Although the recording structure of the image data stored in the above procedure is arbitrary, in order to facilitate the management of the image data, when the image data is recorded on the recording medium 9 with the data structure as shown in FIG. It is preferable to record the data structure while maintaining it. In this case, the recording structure of the image data is as shown in FIG. 10, and a folder (PS_Roll) indicating the storage location of the image data is created at an arbitrary recording position of the hard disk 11, and each medium 8 is provided in the lower hierarchy. A folder (RO030416001_12345601C001) indicating the storage location of image data for each device and film is created, the original image data (OR030416000001.jpg to OR030416000010.jpg) is stored in the folder, and the storage location of thumbnail image data Thumbnail image data (TH030416000001.jpg to TH030416000010.jpg) is stored in the folder (THM) indicating the screen, and screen nail image data (SC030416000001.jpg to SC030416000010.jpg) is stored in the folder (SCREEN) indicating the storage location of the screen nail image data. Stored. In order to facilitate management when storing image data of a plurality of rolls, a folder (PSYYMMDDyyy_XXXXXXAAB: YYMMDD, yyy, XXXXXX, AA) indicating the storage location of the migrated image data in the upper hierarchy of the PS_Roll folder. , B has the same meaning as above).

  Next, in step S207, information about the recording medium 9 is registered as a database so that image data is not stored redundantly when the same recording medium 9 is loaded. The contents of this database are not particularly limited as long as information that can prevent the storage of image data of the same recording medium 9 is registered. For example, an album table in which album information is described, It can be composed of a roll table in which image data group (roll) information is described, a file table in which information on each image data is described, and an exif table in which information on image data in the exif format is described. .

  The album table records identification information (album ID) of the recording medium 9, title of the recording medium 9 (album title), shooting date / time information, and type of stored image data (for example, whether original image data is recorded). Album status indicating whether only reduced image data is recorded), album type indicating whether the album is registered as a favorite, album link indicating whether image data in the album is linked, etc. The roll table is made up of an album ID, image data group (role) identification information (role ID), the total number of images indicating the quantity of image data in the roll, roll creation date / time information, and the like. Roll ID, file name, frame number, file type, file save destination, image rotation Rotation information indicating whether or not the file is linked, file link indicating whether or not the file is linked, storage status indicating whether or not there is original image data, and the exif table includes a role ID and a file name It can be composed of shooting date / time information, image title, image memo, and the like.

  If both pieces of identification information are the same in step S203, in step S208, the data configuration comparison unit 19 determines the data configuration of the image data recorded on the recording medium 9 loaded in the recording medium loading unit 14 (for example, In addition to specifying the type of image data and the quantity of image data of each type, information in a database pre-recorded on the hard disk 11 or the like (in the case of the above configuration, the album type and roll of the album table) With reference to the total number of images in the table, etc., the data structure of the already stored image data is extracted and compared. If the data structure is the same in step S209, it is determined that there is no image data to be newly stored, and the recording control unit 20 prohibits the recording of the image data. If necessary, the data management is performed in step S213. As shown in FIG. 16, a display screen 21 on which a message indicating that the image data recorded on the recording medium 9 has already been stored in a recording destination such as the hard disk 11 is displayed on the display means 12 of the apparatus 10. Display and finish the process.

  If any element in the data structure is different, in step S210, the data structure comparison means 19 specifies image data (difference data) that is not included in the already stored image data, and step S211. Then, the difference data is recorded in a recording destination such as the hard disk 11 using the recording control means 20.

  Specifically, for example, as shown in FIG. 9, original image data and reduced image data (thumbnail image data and screen nail image data) are recorded on the loaded recording medium 9. 11 (a), the data structure comparison means 19 specifies the original image data as difference data, and stores the data already stored in FIG. 11 (b). ), Only the difference data is added to the RO030416001_12345601C001 folder.

  Further, for example, when the image data already stored in the hard disk 11 is only the original image data as shown in FIG. 12A, the data configuration comparison means 19 reduces the reduced image data (thumbnail image data or At least one of the screen nail image data) is specified as difference data, and only the difference data is added to the RO030416001_12345601C001 folder as shown in FIG.

  Further, for example, as shown in FIG. 9, ten pieces of original image data and reduced image data are recorded on the loaded recording medium 9, but the image data already stored in the hard disk 11 is As shown in FIG. 13A, when there are five original image data and ten pieces of reduced image data (thumbnail image data and screen nail image data), the data structure comparison means 19 has five pieces. Original image data (OR030416000006.jpg to OR030416000010.jpg) is specified as difference data, and only the difference data is added to the RO030416001_12345601C001 folder as shown in FIG. 13B.

  Thereafter, in step S212, in order to prevent the image data from being recorded redundantly when the same recording medium 9 is loaded, information regarding the difference data is recorded in the database and the database is updated. As in the above, the contents of this database are not particularly limited as long as information that can prevent the storage of image data on the same recording medium 9 is registered. For example, an album in which album information is described A table, a roll table in which information on each image data group (roll) is described, a file table in which information on each image data is described, and an exif table in which information on image data in the exif format is described. 11 and FIG. 12, the album type of the album table is updated, and in the case of the structure of FIG. 13, the total number of images in the roll table, the file name of the file table, and the like are updated.

  In the above description, when the identification information of the loaded recording medium 9 is the same as the identification information of the registered recording medium in which the image data is already stored, the data structure of the image data is compared. When the information is the same, image data storage may be prohibited immediately without comparing the data structures.

  As described above, in the present embodiment, when the image data recorded on the recording medium 9 is stored in a recording destination such as the hard disk 11 of the data management apparatus 10, first, the identification information of the recording medium is compared, and the identification information is the same. If necessary, compare the data structure of image data (types of image data and the quantity of image data of each type), and if the same image data has already been saved, save the image data. Since the prohibition control is performed, even if the user himself / herself does not determine whether the recording medium 9 is unregistered or registered, the image data recorded on the registered recording medium 9 by mistake is duplicated. Problems such as being stored or being left unsaved can be prevented in advance. In addition, even when image data of a specific type is saved once and then other types of image data are saved, only the difference data is saved and managed, so the image data is reliably saved and managed at the recording destination. can do.

  In the above embodiment, the case where the image data is managed by the management program has been described. However, the present invention is not limited to the above embodiment, and other types of data such as music data and contents are stored by the management program. The same applies to the case of management.

  The management program of the present invention has the following effects.

  The first effect of the present invention is that the user can record only the image data recorded on the unregistered recording medium without determining whether the recording medium is registered or unregistered. .

  The reason is that the management program reads the identification information from the recording medium loaded in the computer and extracts and compares the identification information of the recording medium in which the image data is already stored from the database. In this case, storage to a recording destination such as a hard disk of a computer is prohibited, that is, when the identification information of both is different, storage to the recording destination is permitted and registered in the database, so an image recorded on a registered recording medium This is because data is not stored redundantly.

  The second effect of the present invention is that desired image data can be reliably stored and managed.

  The reason is that if the identification information of the recording medium loaded in the computer is the same as the identification information of the registered recording medium in which the image data is already stored, the image data recorded on the loaded recording medium is further recorded. The data structure (type of image data, quantity of image data of each type, etc.) is compared with the data structure of the already stored image data, and image data (difference data) that is not included in the already stored image data ) Is stored in a recording destination such as a hard disk of a computer. Therefore, even when image data of a specific type is stored once and then image data of another type is stored, only difference data can be stored. Because it can.
