Description

  The present invention relates to a data generation program and a recording apparatus, and more particularly, to a data generation program that converts input image data into moving image data having a predetermined resolution, and a recording apparatus that records the converted moving image data on a recording medium.

  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). In addition, still image data and moving image data obtained by shooting with a digital camera are converted into data in a format such as Video-CD or DVD-Video that can be played back by an image playback device such as a DVD player or DVD recorder. There is also a service for writing to a recording medium such as -R or DVD-R.

JP-A-5-182373 (page 4-6, Fig. 3)

  Digital cameras record high resolution (high pixel count) data so that high-definition photo prints can be created when shooting still images, but in order to reduce the volume of data when shooting movies It is recorded as data having a lower resolution (smaller number of pixels) than still image data.

  Here, when still image data is reproduced as a slide show on an image reproducing device, the still image data is a predetermined format of moving image data (for example, MPEG1 when recording on a CD-R, MPEG2 when recording on a DVD-R). In this case, the still image data is converted into a standard number of pixels of moving image data (for example, in the case of MPEG1, 90 minutes on a CD-R having a capacity of about 700M, regardless of the number of pixels). (The number of pixels of about 352 × 240 set so that a moving image of about a degree can be reproduced).

  For this reason, even if high-resolution still image data is recorded by a digital camera, there is a problem that the image reproducing device can reproduce only an image with a low resolution with a reduced number of pixels. In addition, since the playback time of the slide show is at most about several minutes to several tens of minutes, there is a sufficient margin in the capacity of a recording medium such as a CD-R, and data is created with a higher number of pixels than the standard number of pixels. Therefore, it is hard to say that the current CD-R writing service fully utilizes the capacity of the recording medium.

  In addition, the above-mentioned problems are caused by converting still image data to DVD-Video standard data for recording on DVD-R, or converting still image data to HDTV standard data for recording on Blu-ray discs. This also occurs in the same manner, and not only when image data is recorded on a recording medium, but also when it is recorded on internal storage means such as a hard disk drive.

Particular music data is recorded by compressing the music data dividing means may be configured to perform split after stretching the specific music data.

  In the present invention, it is preferable that the first number of pixels is a standard number of pixels in the standard of moving image data, and the second number of pixels is a maximum number of pixels in the standard of moving image data.

  In the present invention, at least a part of the specific information may be recorded outside the logical address area of the recording medium, and the specific information is provided by a manufacturer of the recording medium. It is preferable that information to be specified and identification information of the recording medium are included.

  As described above, in the data generation program of the present invention, when the input image data is still image data, the number of pixels of the still image data is converted to the maximum resolution (maximum number of pixels) of the standard of the moving image data. When data is created and the input image data is movie data, it is converted to the standard resolution (number of pixels) of the movie data standard, and the movie data created from still image data and the entered movie data Are converted into Video-CD, DVD-Video, and HDTV format data as separate segments, so that an image based on still image data can be reproduced with high resolution. In addition, since music data is divided in correspondence with the display time of the image and the music data divided into the respective moving image data is synthesized, the data for the image playback device divided into segments can be created. It becomes possible to synthesize music data.

  According to the data generation program and the recording apparatus of the present invention, the following effects can be obtained.

  The first effect of the present invention is that even when data in which still image data and moving image data are mixed is converted into video-CD, DVD-Video, or HDTV format data that can be reproduced by an image reproducing device, the still image data is converted into still image data. The image based on it can be reproduced with high resolution.

  The reason is that when the input image data is still image data, the number of pixels of the still image data is set to the maximum resolution of the standard of moving image data (for example, more than 352 × 240 pixels in the case of CD-R, preferably 702 × 480 pixels, DVD-R has more than 720 × 480 pixels, preferably 1024 × 768 pixels, and Blu-ray disc has more than 700 pixels in the vertical direction, preferably 1280 × 1024 pixels) If the input image data is moving image data, the standard resolution of the moving image data standard (for example, 352 × 240 pixels for CD-R, DVD-R In the case of Blu-ray disc, about 700 pixels in the vertical direction), and moving image data created from still image data. Video-CD input and a video data as separate segments and, because are converted DVD-Video, the data of the HDTV format.

  Further, the second effect of the present invention is that music data can be synthesized even in a configuration for creating data for an image reproducing device divided into segments.

  The reason is that the music slide playback time of the image based on the still image data is not calculated based on the playback time of the music data and the playback time of the input video data. This is because the music data is calculated and divided in correspondence with the display time of the image, and the divided music data is synthesized into each moving image data.

  In a preferred embodiment of the recording apparatus of the present invention, a data input means for inputting still image data and moving image data from a digital camera or media, a type of the input image data, and an input image When the data is still image data, the number of pixels of the still image data is set to the maximum number of pixels of the standard of moving image data (for example, in the case of CD-R, the number of pixels is larger than 352 × 240, preferably 702 × 480 pixels, In the case of R, the number of pixels is larger than 720 × 480, preferably 1024 × 768 pixels, and in the case of a Blu-ray disc, the number of pixels is larger than 700 pixels in the vertical direction, preferably 1280 × 1024 pixels. If the input image data is moving image data, the standard resolution of the moving image data standard (for example, 35 for CD-R). 2 × 240 pixels, 720 × 480 pixels in the case of DVD-R, and about 700 pixels in the vertical direction in the case of Blu-ray disc), and moving image data created from still image data and input as necessary Data conversion in which each piece of moving image data is combined with music data divided in association with the playback time of the image, and then each piece of moving image data is converted into Video-CD, DVD-Video, HDTV format data as one segment Means and data recording means for recording the input image data and the converted data on a recording medium such as a CD-R / RW, DVD ± R / RW, DVD-RAM, Blu-ray disc, etc. Yes, image data from a DVD player, DVD recorder, etc. can be reproduced from a mixture of still image data and video data. Even when converted into a reproduction data in vessel, it is possible to reproduce an image based on the still image data at high resolution.

  In order to describe the above embodiment in detail, a data generation program and a recording apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5 are external views schematically illustrating the configuration of the recording apparatus according to the present embodiment, and FIG. 6 is a block diagram illustrating functions of the recording apparatus.

A recording medium (hereinafter, referred to as a medium 8), and a photographing apparatus (hereinafter, referred to as a digital camera 7) such as a digital camera 7 or a camera-equipped mobile phone 7a. Data connection means such as a device connection unit 3 for connection by means of a network, a network connection unit for downloading data from a server 17 via a communication network 16 such as the Internet, input still image data, moving image data, music data, etc. Data converted from data, application data, etc. A recording medium loading unit 4 for loading a recording medium 9 such as a CD-R / RW, DVD ± R / RW, DVD-RAM, or Blu-ray disc to be recorded; an operation unit 6 such as a button, a keyboard, a mouse, and an LCD; And a display unit 5 such as a CRT (a touch panel having both the operation unit 6 and the display unit 5 is shown in the figure).

  Further, the function of the recording apparatus 1 is shown in a block diagram as shown in FIG. That is, the data input means 10 for inputting still image data, moving image data, music data, etc. from the digital camera 7 or the media 8 using the media loading unit 2, the device connection unit 3, the network connection unit, etc., the display unit 5 and the operation Unit 6 and data generation means 11 for generating standard data such as Video-CD, DVD-Video, HDTV and the like that can be used in an image reproducing device such as a DVD player or a DVD recorder from the input image data, Data recording means 15 for recording still image data, moving image data, generated data, and the like on the recording medium 9 loaded in the recording medium loading unit 4 is provided.

  In addition, when the input image data is still image data, the data generation unit 11 sets the number of pixels (hereinafter referred to as the first pixel) set as a standard among the number of pixels that can be set according to the moving image data standard. For example, the number of pixels is 352 × 240 pixels for a CD-R, 720 × 480 pixels for a DVD-R, and about 700 pixels in the vertical direction for a Blu-ray disc. For example, in the case of CD-R, the number of pixels is larger than 352 × 240, preferably 702 × 480 pixels, and in the case of DVD-R, the number of pixels is larger than 720 × 480, preferably 1024 ×. In the case of a 768-pixel Blu-ray disc, the data is resized to data with more than 700 pixels in the vertical direction (preferably 1280 × 1024 pixels), and the input data is moving image data The resolution converting means 12 for resizing the data to the standard set number of pixels (first number of pixels), and if necessary, the predetermined music data is reproduced together with the display of the image based on the still image data. The music data dividing means 13 for dividing the still image music data and the moving image music data to be reproduced together with the reproduction of the moving image, the moving image data created based on the still image data and the input moving image data, respectively. Data conversion means 14 for converting the data into data that can be used by the image reproducing device as a segment. Further, the data recording means 15 reads the identification information written in the recording medium 9 loaded in the recording medium loading unit 4 as necessary, and whether the recording medium 9 is permitted to record data. The recording medium identification means 15a for judging whether or not is provided.

  Each of the above means may be configured as hardware in the recording apparatus 1, or a data generation program for causing the computer to function as the resolution converting means 12, the music data dividing means 13, the data converting means 14, etc. is installed. The above means may be executed by the data generation program. 1 shows a kiosk-type recording apparatus 1 that can be installed in a store such as a photo shop or a convenience store. However, the recording apparatus 1 can take any form, for example, a personal computer as shown in FIG. Or a dedicated set-top box as shown in FIG. 3, a portable writer as shown in FIG. 4, or a DVD recorder or HDD recorder as shown in FIG. Etc. may be used.

  Next, a procedure until data is recorded on the recording medium 9 using the recording apparatus 1 having the above-described configuration will be described with reference to a flowchart of FIG. 7, a schematic diagram of FIG. 8, and a data structure example of FIG. To do. In the following, a case where still image data and moving image data are converted into data of the Video-CD standard will be described, but the present invention can be similarly applied to a case of converting into data of a standard such as DVD-Video or HDTV. In addition, music data is synthesized so that music is reproduced as BGM when displaying an image based on still image data and an image based on moving image data. However, if BGM is not used, it is necessary to synthesize music data. There is no.

  First, in step S 101, the medium 8 is loaded into the medium loading unit 2 of the recording apparatus 1, the digital camera 7 is connected to the device connection unit 3, or the network connection unit is connected to the communication network 16. A recording medium 9 such as a CD-R / RW, a DVD ± R / RW, a DVD-RAM, or a Blu-ray disc is loaded and stored in the digital camera 7 or the medium 8 using the data input means 10 in step S102. Still image data, moving image data, and music data recorded in the server 17 are input. The recording medium 9 loaded in the recording medium loading unit 4 may be an unused recording medium in which no data is recorded, or a recording medium in which an application or the like is recorded in advance. The music data may be input by the data input means 10, or the recording device 1 may be provided with storage means in advance and the music data stored in the storage means may be used.

  Next, in step S103, it is determined whether to synthesize music data. Here, in the conventional recording apparatus, the moving image data created from the still image data and the input moving image data are collectively converted into data that can be reproduced by the image reproducing device, but the recording apparatus 1 of the present embodiment. Then, since the moving image data created from the still image data and the input moving image data are each converted as one segment data, it is necessary to synthesize the music data separately for each image data. Therefore, in this embodiment, when combining music data, the music data is divided into the number of segments of music data by using the music data dividing means 13 in step S104.

  As a method for dividing the music data, for example, the time for sliding display of each still image data is calculated from the playback time of the music data and the playback time of the moving image data, and the music data is stopped based on the display time of these images. The image data is divided into still image music data to be played back when the image data is displayed on the slide and moving image music data to be played back when the movie data is played back. As shown in FIG. 8, it is assumed that three still image data (DSC00001.jpg, DSC00002.jpg, DSC00003.jpg) and one video data (DSC00005.avi) are input and played back in this order. When music data (BGM1.mp3) is played back as BGM during playback of image data, for example, the case where the playback time of music data is 50 seconds and the playback time of moving picture data is 20 seconds is shown in FIG. This will be specifically described with reference to the flowchart of FIG.

  First, in step S201, the reproduction time of the music data is acquired with reference to the header information of the music data, and in step S202, the reproduction time of the video data is acquired with reference to the header information of the video data. Next, in step S203, the header portion of the music data (BGM1.mp3 in FIG. 8) is separated from the main data, and in step S204, the main data is decompressed and restored to music PCM data.

  Next, in step S205, the music PCM data is divided in accordance with the reproduction time of the moving image data to create still image music PCM data and moving image music PCM data. Here, since the reproduction time of the moving image data is 20 seconds, the first 30 seconds of the music PCM data are set as still image music PCM data, and the remaining 20 seconds are set as moving image music PCM data. Since there are three still images for slide display, the slide display time for each still image data is set to 10 seconds.

  Next, in step S206, the still image music PCM data is compressed, and a header is added to create still image music data (BGM1S.mp3) (S207). Similarly, in step S208, the moving image music PCM data is created. The data is compressed and a header is added to create moving image music data (BGM1M.mp3) (step S209). In this way, the music data (BGM1.mp3) includes the music data for still images (BGM1S.mp3) in which the first 30 seconds of music is recorded and the music data for movies (BGM1M in which the remaining 20 seconds of music are recorded). .mp3).

  The above description is a dividing method in the case where music playback is also ended when the slide display of still image data and the playback of moving image data ends (that is, the display of the image and the music playback are synchronized). The data division method is not limited to the above description, and the slide time of the still image data is set in advance, and the image is displayed regardless of the music playback time (that is, the image display and the music playback are not synchronized). It is good also as a structure. Further, as described above, the synthesis of music data is not essential, and this step is not necessary when music data is not synthesized.

  Next, data that can be played back by the image playback device is created using the input image data. In this embodiment, the subsequent processing depends on whether the input image data is still image data or moving image data. In step S105, the type of the input image data is determined with reference to the extension of the image data.

  If the input image data is still image data, in step S106, the resolution conversion means 12 is used to obtain the number of pixels of the input still image data by referring to header information and the like. When the number is different from the predetermined second number of pixels, the number of pixels of the still image data is resized to the second number of pixels. The second number of pixels is the maximum number of pixels that can be selected from among the number of pixels that can be set according to the video data standard. For example, in the case of CD-R, the number of pixels is larger than 352 × 240, preferably 702. In the case of DVD × R, the number of pixels is more than 720 × 480, preferably 1024 × 768 pixels, and in the case of a Blu-ray disc, the number of pixels is more than 700 pixels in the vertical direction, preferably 1280 × 1024 pixels. The relationship between the number of pixels of still image data and the second number of pixels may be the same as the case where the number of pixels of still image data is higher or lower than the second number of pixels. When the number of pixels of data is higher, the pixels of still image data are thinned out to obtain the second number of pixels, and when the number of pixels of still image data is lower, the pixels of still image data are complemented to obtain the second number of pixels. If the number of pixels is the same and the number of pixels of the still image data is the same as the second number of pixels, resizing is not necessary.

  Next, moving image data is created based on the resized still image data. However, the image data is usually configured as RGB light emission three primary color data, and it is difficult to increase the degree of compression of the image data in the RGB method. Here, since the resolution of the human eye is not as sensitive to the luminance as the luminance, the image data is converted into the YUV format (the luminance, the difference between the luminance and the red component, and the difference between the luminance and the blue component). It is also possible to configure in the YUV format, and by configuring in the YUV format, the amount of information can be reduced by thinning out the color information. Therefore, in this embodiment, in step S107, the data conversion means 14 is used to convert RGB format data into YUV format data (DSC00001.yuv, DSC00002.yuv, DSC00003.yuv). It should be noted that the data conversion in this step is not essential, and if the recording capacity of the recording medium 9 is sufficient, moving image data may be created directly from RGB format data.

  Next, in step S108, moving image data (here, moving image data in MPEG1 format: Stillmovie.mpg) is created from the still image data converted into the YUV format. The method of creating the moving image data is not particularly limited. For example, when still image data is displayed like a slide show, the slide display time set in step S104 or the preset slide display time is multiplied by 30 frames / second. It is possible to create moving image data by superimposing a number of still image data. At that time, when reproducing still image data based on the slide effect set in the slide show program, it is only necessary to add difference data based on the slide effect to generate moving image data, or to display the same image for a certain period of time. The moving image data may be generated by adding data with a difference 0 corresponding to the slide display time.

  Next, in step S109, music data is synthesized with the moving image data. In this embodiment, since the music data input as described above is divided in advance based on the slide display time of the still image data, the moving image data (Stillmovie.mpg) created in step S108 and the step In S104, the music data (BGM1S.mp3) divided by the music data dividing means 13 is synthesized. As a result, data in which the image display time and the music playback time are synchronized can be generated.

  Next, in step S110, the data conversion means 14 is used to convert the MPEG1 format moving image data combined with the music data into data in a format that can be played back by an image playback device (for example, Video-CD in the case of CD-R). DVD-R in the case of DVD-R and HDTV data in the case of Blu-ray disc). Here, in the conventional recording apparatus, the moving image data created from the still image data and the input moving image data are collectively converted into one data, but in this embodiment, the image data having a different number of pixels is converted. Therefore, only moving image data (Stillmovie.mpg) created from still image data is converted as one segment. Note that reduced image data (thumbnail image data, screen nail image data, etc.) obtained by reducing the data size of still image data may be created as necessary.

  On the other hand, if the image data input in step S105 is moving image data (DSC00005.avi), the number of pixels of the moving image data input with reference to the header information or the like using the resolution conversion unit 12 in step S111. When the number of pixels is different from the predetermined first number of pixels, the number of pixels of the moving image data is resized to the first number of pixels. The first number of pixels is a standard number of pixels in the standard of moving image data. For example, 352 × 240 pixels in the case of CD-R, 720 × 480 pixels in the case of DVD-R, Blu-ray disc In this case, the vertical direction is about 700 pixels. Note that the relationship between the number of pixels of the moving image data and the first number of pixels may be the case where the number of pixels of the moving image data is higher than the first pixel number, or the same as the case where the number of pixels is lower. If the number is higher, the video data pixels are thinned out to the first pixel number, and if the video data pixel number is lower, the video data pixels are complemented to the first pixel number. If the number of pixels and the first number of pixels are the same, resizing is not necessary.

  Next, in step S112, the moving image data in the AVI format is converted into moving image data in the MPEG1 format so that it can be reproduced by the image reproducing device.

  Next, in step S113, music data is synthesized with the moving image data. Also in this embodiment, since the music data input as described above is divided in advance based on the reproduction time of the moving image data, the moving image data (Movie1.mpg) converted in step S112 and the step S104 are used. The music data (BGM1M.mp3) divided by the music data dividing means 13 is synthesized. As a result, data in which the image display time and the music playback time are synchronized can be generated.

  Next, in step S114, the data conversion unit 14 is used to convert the MPEG1 format moving image data combined with the music data into data in a format that can be played back by an image playback device (for example, Video-CD in the case of a CD-R). DVD-R in the case of DVD-R and HDTV data in the case of Blu-ray disc). Here, in the conventional recording apparatus, the moving image data created from the still image data and the input moving image data are collectively converted to create one data, but in this embodiment, the moving image data (Movie1) .mpg) is converted as one segment.

  Next, the data is recorded on the recording medium 9. At this time, the data may be recorded on an arbitrary recording medium 9, or the data may be recorded only on the recording medium 9 which is properly created. Recording may be permitted. In the latter case, for example, in step S115, using the recording medium identifying unit 15a, the position information (for example, physical address) stored in advance in the storage unit is referred to, and specific identification information is written in advance at the position. It can be determined whether or not the data recording means 15 starts data recording 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 personal computer (that is, outside the logical address area), specifically, in the logical address area of the disk type recording medium. It is preferably written in the inner area.

  Here, the structure of a general recording medium 9 will be described with reference to FIG. 12. 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 a protective layer 103 are laminated to form a pit by applying laser light of a predetermined power to the organic dye layer 101 to decompose the dye and deform the substrate, thereby recording information. However, since the optimum value of the laser power varies depending on the type of the laser head that irradiates the laser beam and the type of the organic dye layer 101 to be used, the CD-R is required to reliably write and read information. It is necessary for the drive side to recognize what kind of dye is used. 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 and may be any information that can be identified at least by the recording medium identifying means 15a. However, as described above, the manufacturer's name is recorded in advance outside the logical address area of the recording medium 9. Therefore, by using the manufacturer's name and the number assigned to the recording medium 9 as identification information, it is easily and reliably identified whether or not the recording medium 9 has been properly created. be able to.

  In step S116, the moving image data converted according to the above procedure and the input data (still image data, moving image data, music data, etc.) are recorded on the recording medium 9 in which the identification information is written. Since the recording area in which data can be read is limited in the device, first, the moving image data converted in steps S110 and S114, the association file, and the like (hereinafter collectively referred to as an image reproduction device data group). Is transferred to a predetermined folder for writing, and the data recording unit 15 is used to read out the image reproduction device data group from the folder and record it inside the logical address area of the recording medium 9. Then, the session is temporarily closed in order to classify the data area that can be used by the image playback device.

  Next, input data (still image data, moving image data, music data, etc.), reduced image data created as necessary, applications such as slide show programs, setting files, etc. (hereinafter collectively referred to as computer) (Referred to as a device data group) is transferred to a predetermined folder for writing, and the data recording means 15 is used to read the computer device data group from the folder and record it on the recording medium 9 first. The data is recorded outside the image reproduction device data group, and a series of writing processes is completed.

  Various types of information are recorded on the recording medium 9 created in the above procedure, as shown in FIG. 11, and a predetermined format (preferably a data format that is not a file format) is located outside the innermost logical address area of the disc type recording medium 9. ) Identification information is recorded, an image reproduction device data group is recorded inside the logical address area outside, and a computer device data group is recorded further outside.

  Further, the recording structure of the recording medium 9 (CD-R) created by the above procedure is as shown in FIG. 9, for example, such as image data, thumbnail image data, screen nail image data in the “PS_Roll” folder. The image data group, the slide show program in the “APPL” folder, the slide show setting file, and the automatic startup file (Autrun.inf) constitute a computer data group, and the image data in the “VCD” folder is converted to the Video- Files to be associated as data for CD format, DVD-Video format, HDTV format, etc., image data to be displayed on TV screen in “SEGMENT” folder, moving image data in “MPEGAV” folder, still image on TV screen in “DAT” folder An image reproducing device data group is configured by an application for displaying image data.

  Further, the recording structure of the recording medium 9 (DVD-R) is as shown in FIG. 10, for example, and a data group for computer equipment similar to the above is configured, and the video manager (VMG) in the “VIDEO_TS” folder The video title set (VTS) constitutes a data group (DVD-Video data) for image playback equipment. More specifically, the VMG is composed of VIDEO_TS.IFO in which information for controlling the entire video is recorded, VIDEO_TS.BUP which is a backup file thereof, and VIDEO_TS.VOB file for a title selection menu. , VTS _ ** _ 0.IFO that describes the information that controls the entire VTS, VTS _ ** _ 0.BUP that is the backup file, VTS _ ** _ *. VOB that is the video data of each VTS title, etc. The

  The recording structure of the image data group is arbitrary, but in order to facilitate the management of the image data, it is preferable to configure a folder according to a predetermined rule and give a unique name to the folder. For example, as shown in FIG. 9 and FIG. 10, a folder (RO_AABC_XXXXX_YYMMDD_yyy_zzz) indicating the storage location of image data for each medium 8, each device, and each film is provided in the lower hierarchy of the folder (PS_Roll) indicating the storage location of image data. Create each element, AA: country-specific code number (00 to ZZ), B: region-specific code number (0 to Z), C: code number indicating how to make the recording medium (for example, a kiosk XXXXX: Random ID number, yymmdd: Number specifying the date of writing, yyy: Sequential number for each day, zzz: For each predetermined unit (for example, film) It may be a sequential number or the like for each, each medium, or each device. In addition, a folder (PS_AABC_XXXXX_YYMMDD_zzz) indicating the storage location of image data that has migrated to a higher level of the PS_Roll folder may be created.

  As described above, in the data generation program and the recording apparatus of the present embodiment, when the input image data is still image data, the number of pixels of the still image data is set to the maximum resolution (for example, CD-R) of the moving image data standard. Is more than 352 x 240 pixels, preferably 702 x 480 pixels, DVD-R is more than 720 x 480 pixels, preferably 1024 x 768 pixels, and Blu-ray disc is 700 pixels in the vertical direction. When moving image data is created by converting to a larger number of pixels, preferably 1280 × 1024 pixels, and the input image data is moving image data, the standard resolution of the moving image data standard (for example, CD-R) Is 352 x 240 pixels, DVD-R is 720 x 480 pixels, and Blu-ray disc is about 700 pixels in the vertical direction. If necessary, after combining the music data divided in correspondence with the display time of the image, the moving image data created from the still image data and the input moving image data are separated into Video- Since the data is converted into data in the CD, DVD-Video, or HDTV format, an image based on still image data can be reproduced with high resolution even if the data is a mixture of still image data and moving image data.

  In the above description, the number of pixels of both the input still image data and moving image data is resized. However, since the number of pixels of moving image data is usually standard pixel number data, Only one of the image data may be resized, for example, the number of pixels may be resized only for the data. In addition, the converted data and the input data are written in the recording medium 9, but the data may be written in other recording means (for example, HDD of a computer device).
