Description

  The present invention relates to a recording apparatus and a recording program for recording a plurality of types of data.

  In recent years, various services related to photography have been provided. For example, when a user takes a picture with a digital camera and brings a digital camera or digital camera media in which still picture data or moving picture data of the photograph is recorded to a photo shop such as a minilab, the digital camera uses a recording device at the photo shop. In addition, there is a service for reading still image data and moving image data from a medium and writing it on a recording medium such as a CD-R or DVD-R (for example, Patent Document 1 below). Still image data and moving image data obtained by photographing with a digital camera are converted into data in a Video-CD format or a DVD-Video format that can be played back by an image playback device such as a DVD player or a DVD recorder. There is also a service for writing to a recording medium such as -R or DVD-R.

  It is preferable that a plurality of image data obtained by photographing is managed in order of date and time such as photographing order because of its characteristics. Here, in the digital camera, a file name generated using a serial number is assigned to the image data obtained by shooting, and therefore the image data recorded on one digital camera or media is the file name as it is. In this case, the image data can be managed in the order of photographing.

  However, when inputting image data from a plurality of digital cameras or media, the file name is uniquely generated for each digital camera or each medium. Therefore, even if these image data are arranged in descending or ascending order of the file name, Therefore, a plurality of image data cannot be managed in the shooting order. In addition, when the file names are duplicated, the image data cannot be recorded, or the image data is overwritten, so that a plurality of image data cannot be recorded on the recording medium. The above problem is not limited to the case where image data is input from a plurality of digital cameras or media, but also occurs when image data is further added from a digital camera or media to a recording medium on which image data has been once recorded.

  When the file name is composed of a symbol and a serial number for determining the type of image data, a plurality of types of image data (for example, still image data and moving image data) are arranged in descending or ascending order of the file name. Since these image data are divided for each type, image data in which a plurality of types are mixed cannot be managed in the shooting order. Furthermore, such a problem occurs not only in image data but also in other types of data such as audio data, and also occurs when image data and audio data coexist.

  The present invention has been made in view of the above problems, and its main purpose is to record at least still image data among a plurality of types of data on a recording medium so that it can be managed based on date and time information.

Data type specifying means 13 for specifying whether it is still image data, moving image data, audio data, etc., and information described in the header and the management file The date and time information associated with at least still image data among multiple types of data (such as shooting date and time, creation date and time, modification date and time for still image data or video data, recording for audio data) Date / time, creation date / time, modification date / time, etc. In the following, as representatives thereof, the date / time information extracting means 14 for extracting the shooting date / time for still image data or moving image data, and the recording date / time for sound data) Renaming means 15 for renaming at least the file name of still image data to a file name numbered based on date and time information, and a thumbnail image in which the data size of the image data is reduced as necessary Create reduced image data, such as data and screen nail image data, and save image data to a DVD player, DVD recorder, Data generation means 16 for generating data in Video-CD format, DVD-Video format, HDTV format and the like that can be read by an image playback device such as a DD recorder or game machine; data renamed by the rename means 15; Accordingly, a data recording unit 17 that records data generated by the data generation unit 16 in a recording unit such as the recording medium 9, a display unit 5, and an operation unit 6 are provided.

  Although FIG. 1 shows an unmanned terminal (kiosk) installed in a store such as a photo shop or a convenience store as the recording device 1, the form of the recording device 1 is arbitrary, for example, as shown in FIG. A computer device such as a personal computer, a dedicated set-top box as shown in FIG. 3, a portable writer as shown in FIG. 4, an HDD recorder having an arithmetic processing function as shown in FIG. A DVD recorder, a game machine, or the like may be used, or a car navigation device having an arithmetic processing function may be used. Each of the above units may be configured as hardware in the recording device 1, but at least a recording that causes the computer to function as the data type specifying unit 13, date / time information extracting unit 14, renaming unit 15, and data recording unit 17. It is good also as a structure which comprises as a program and installs this recording program in the recording apparatus 1, and performs it.

  Next, a procedure for recording a plurality of types of data on the recording medium 9 using the recording apparatus 1 (recording program) having the above configuration will be described with reference to the flowchart of FIG. In the following, a case where data is input from the two media 8 will be described, but the data input source, the number, the combination, and the like are arbitrary. In addition, as the data to be input, three types of data of still image data, moving image data, and audio data are used, but the type of data is also arbitrary, and a configuration in which a plurality of types of data including at least still image data is input If it is. In the following, a case where a plurality of types of data is recorded on the recording medium 9 will be described.

  First, in step S101, a recording medium 9 such as a CD-R / RW, DVD ± R / RW, DVD-RAM, or Blu-ray disc is loaded into the recording medium loading unit 4 of the recording apparatus 1. Any recording medium may be used as the recording medium 9, but only a recording medium in which predetermined identification information is written can be used in order to prevent unauthorized copying of data. Reads the identification information from the specific area of the recording medium 9 in step S102. At that time, since the identification information is provided for recording data on an appropriate recording medium, if the recording location and contents of the identification information are easily known, the identification information itself is also copied, Since data cannot be recorded, at least a part of the identification information is information that cannot be recorded by the computer OS, specifically, information in the program memory area, and guidance given at the time of CD-R molding. It is preferable to use information by groove modulation (ATIP).

  Here, the structure of a general recording medium will be described with reference to FIG. 9. 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 102 such as silver. And a protective 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. The laser power has an optimum value depending on the type of the laser head that irradiates the laser light and the type of the organic dye layer 101 to be used. Therefore, in order to reliably write information, the CD-R type or laser It is necessary for the drive side to recognize the recommended recording power. Therefore, information such as the disc application code and recommended laser recording power is written as guide groove modulation (ATIP) information at the manufacturing stage of the recording medium, and the information is read by the drive firmware. The laser power is adjusted by control. Since such guide groove modulation (ATIP) can only be created at the time of manufacture, copying at the user level can be prevented.

  The specific configuration of this identification information is arbitrary, and it can be used as identification information by appropriately setting lead-in start time, maximum lead-out start possible time, etc., other than guide groove modulation (ATIP). It is possible to easily and reliably identify whether the recording medium is properly created.

  Next, when the identification information is recorded in a predetermined area of the recording medium 9, the medium 8 is loaded into the medium loading unit 2 of the recording apparatus 1 or the digital camera 7 is loaded into the device connection unit 3 in step S103. Or a camera-equipped mobile phone 7a or a network connection unit connected to the communication network 10, and in step S104, using the data input means 12, a plurality of digital images including the still image data from the digital camera 7, the media 8, and the server 11 are used. Read data of type. At that time, data to be written on the recording medium may be selected using the display means 5 and the operation means 6.

  Here, it is assumed that data is input from the two media 8 as described above, and data as shown in FIG. 10 is recorded on each medium. Specifically, as shown in FIG. 10A, the first media includes four still image data (DSC00001.jpg, DSC00002.jpg, DSC00003.jpg, DSC00006.jpg) and two moving image data ( DSC00004.mpeg1, DSC00005.mpeg1) and one audio data (DSC00007.mp3) are recorded, and the second medium has two still image data (DSC00101.jpg, DSC00102.jpg), one video data (DSC00103.mpeg1), and two audio data (DSC00104.mp3, DSC00105.mp3) are recorded, and each data includes date and time information (still image data) associated with the data. And video data describe the shooting date and time, and audio data the recording date and time). In this example, jpeg is used as still image data, mpeg1 is used as moving image data, and mp3 is used as audio data. However, the format of each data is arbitrary, and bmp, gif, and tiff are used as still image data. , Exif (Exchangeable image file format), etc. Data in a format such as avi or mov may be used as moving image data, and wav may be used as audio data.

  Next, in step S105, the type of the read data is specified using the data type specifying unit 13. The type of data can be specified by referring to the extension of each data, information described in the header, a management file in which information related to these data is described, and the like.

  Next, in step S106, date / time information extraction means 14 is used to extract date / time information from at least still image data among a plurality of types of data. This date / time information can be extracted with reference to information described in the header of each data, the management file, or the like. For example, in the case of exif data, date information such as shooting date and time is included in the exif information, so that the date information can be extracted by reading the information of the item. In addition, when the information file is a dedicated file recommended in the photographic industry (for example, a file with an extension of pvm), the image header information recorded at the time of shooting is recorded in the file of this format. The date and time information can be extracted from them. When only still image data is managed by date information, it is not necessary to extract date information for other types of data.

  Next, in step S107, the renaming unit 15 is used to rearrange various read data for each type specified by the data type specifying unit 13 based on the date information extracted by the date information extracting unit 14, and a plurality of data is sorted. Of the data of the type, at least the file name of the still image data is renamed to a file name numbered based on the date / time information according to a predetermined rule. For example, when renaming all types of data, the various data shown in FIG. 11A is classified by data type, as shown in FIG. 11B. When the data is rearranged in order of date and time, the order is as shown in FIG. 11C, and the file name generation rule is CCYYMMDDxxxxxx (CC: type of data ("OR" for still image data, "MV" for video data) , Audio data is “VC”), YYMMDD: number specifying the date of writing (here, 03/04/16), xxxxxx: sequential number), the rearranged data is as shown in FIG. As shown in (d), still image data has a file name with a serial number from OR030416000001 to OR03041600006, moving image data has a serial number from MV030416000001 to MV03041600003, and audio data has a serial number from VC030416000001 to VC03041600003.

  Next, in step S108, 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 using the data generation unit 16 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 S109, if necessary, the data generation means 16 is used to generate moving image data based on the read image data, and then, if necessary, music to be BGM is recorded in the moving image data. Music data is synthesized, and the synthesized moving image data can be played back by the image playback device 30 such as a DVD player, DVD recorder, HDD recorder, game machine (data in Video-CD format, DVD-Video format, HDTV format, etc.) ). 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, the moving image is generated by adding data with a difference of 0 corresponding to the slide display time to the still image data. Data may be generated, or moving image data may be generated by adding difference data based on the slide effect set by the slide show program to still image data.

  Next, in step S110, various types of data are written to the recording medium 9. At that time, since the area where the data can be read is limited in the image reproducing device, the data is first generated using the data recording unit 17. Data for image playback equipment, associated files, etc. (hereinafter collectively referred to as image playback equipment data group) are written inside the recording medium 9 and the session is closed if necessary. Original data renamed every time, reduced image data and information files as required, music data used as BGM, and the like (hereinafter collectively referred to as a computer equipment data group) are data reproduction equipment data group. End the writing process outside.

  As shown in FIG. 8, various information is recorded on the recording medium 9 created in the above procedure, and outside the innermost logical address area of the disk-type recording medium 9, a predetermined format (preferably data that is not a file name expression) Format) identification information is recorded, a data group for image reproduction equipment is recorded inside the logical address area on the outer side, and a data group for computer equipment including original data renamed for each type is recorded on the outer side. Is recorded.

  Further, for example, as shown in FIG. 12, various data are recorded in the recording medium 9 created in the above procedure, and still image data renamed with reference to date / time information in the “PS_Roll” folder, Original data such as movie data renamed with reference to date / time information as needed in the “MOVIE” folder, audio data renamed with reference to date / time information as needed in the “VOICE” folder Is recorded, and if necessary, thumbnail image data, screen nail image data, information file (info.txt), slide show program in the “APPL” folder, slide show setting file, auto start file (Autorun.inf) ) And the like, and the data group for the computer equipment is configured, and the image data in the “VCD” folder is converted into Video-CD format, DVD-Vid. File to be linked as eo format, HDTV format data, image data to be displayed on TV screen in “SEGMENT” folder, video data in “MPEGAV” folder, still image data to be displayed on TV screen in “DAT” folder A data group for an image reproduction device is configured by an application for the purpose.

  In order to facilitate management when recording the original data or the like when backing up to a data management device or the like, a folder can be configured according to a predetermined rule, and a unique name can be given to the folder. . For example, as shown in FIG. 12, folders (ROYYMMDDyyy_XXXXXXAABxxx, YYMMDD: writing year) indicating the storage location of image data for each medium 8, each device, and each film in the lower hierarchy of the folder (PS_Roll) indicating the storage location of image data Number specifying month and day, yyy: Sequential number for each day, XXXXXX: Random ID number, AA: Manufacturer code (00 to ZZ), B: Product category of software and equipment (0 to Z), xxx: Sequential number) Can be managed and data management can be further facilitated by recording various renamed data in the folder.

  As described above, the recording apparatus 1 of the present embodiment reads a plurality of types of data such as image data and audio data, classifies the read image data and audio data for each type, and obtains date and time information from at least still image data. After extracting and renaming at least the still image data file name to the file name numbered according to the date and time information, it is recorded on the recording medium 9 together with the reduced image data, the data for image reproduction equipment, etc. Among them, at least still image data can be recorded on a recording medium so as to be managed in order of date and time.

  In the above-described embodiment, the case where data composed of still image data, moving image data, and audio data is recorded has been described. However, the present invention is not limited to the above-described embodiment. The same applies to the case of including data of a type.
