Description

  The present invention relates to a program and a method for generating data, and more particularly to a data generation program and a data generation method for generating data for a slide show with music.

  In recent years, various services relating to photographic images have been provided. For example, when a digital camera or digital camera media is brought into a photo shop such as a mini-lab, the image data is read from the digital camera or media using a reception terminal provided in the store, and the read image data is CD- A process of writing to a recording medium such as R or DVD-R is performed.

  In addition, when a photographed film is brought into a photo shop such as a minilab, the photo shop reads the image data from the developed film using a scanner after developing the film, and reads the read image data into a CD-R, A process of writing to a recording medium such as a DVD-R is performed.

  Furthermore, Video-CD format data or DVD-Video format data (for playback of a slide show on home appliances such as a DVD player, a DVD recorder, and a game machine using image data read from a film, a digital camera, media, or the like ( Hereinafter, data for a slide show to be played back on a home appliance is referred to as “home appliance data”), and the read image data or home appliance data generated together with the application is recorded on a CD-R, DVD-R, or the like. A process of writing to the medium is also performed (see, for example, Patent Document 1 below).

JP 2003-259303 A (Page 5-11, FIG. 4)

  When generating the data for home appliances, there is an appropriate relationship between the time during which an image based on the selected image data is displayed (image reproduction time) and the performance time (music reproduction time) of the music data selected as the slide show BGM. In this case, you can create a slide show that combines the image and music by synchronizing the image display and music playback, but if the image playback time is longer than the music playback time, If all the images cannot be displayed during music data playback, and if the image playback time is shorter than the music playback time, the music data will be played after the image display ends. The problem occurs.

  Therefore, the display unit displays an image reproduction range in which an image based on the selected image data is displayed at an appropriate slide interval, and music data having an appropriate performance time is selected with reference to the image reproduction time range. However, if there is no music data with a performance time within the image playback time range, or if the user selects music data with a performance time outside the image playback time range, the image and music There is a problem that it is impossible to create a slide show in which the two are integrated.

  The present invention has been made in view of the above-mentioned problems, and its main purpose is to provide an image and music that are integrated even when the image playback time and the music playback time are not in an appropriate relationship. It is an object to provide a data generation program and a data generation method capable of creating a slide show with music.

  Thus, according to the present invention, when the performance time of music data (music playback time) exceeds the range of the image display time (image playback time) based on the image data, or the music playback time is equal to the image playback time. If it is less than the range, the excess time or shortage time is compared with a predetermined time, and based on the comparison result, image data and music data are repeatedly reproduced, and the last image data for the excess time is displayed. The slide show playback conditions are set so that the image data is played back for a long time or without music, and the slide show data is generated according to the set playback conditions. Even if the relationship is not appropriate, it is easy to create a nice-looking slideshow with music that plays back images and music together. That.

  According to the data generation program and the data generation method of the present invention, even if the relationship between the image reproduction time and the music reproduction time is not appropriate, the image and the music are reproduced together with the good-looking music. You can easily create a slide show.

  The reason is that the data generation program displays an image based on the image data based on the quantity of the selected still image data, the maximum and minimum values of the predetermined slide interval, and the reproduction time of the moving image data as necessary. When the performance time (music reproduction time) of the selected music data or music data exceeds the image reproduction time range, the excess time is determined in advance. The slideshow playback conditions are set so that the specified image data is repeatedly played for the excess time if it is longer than the specified time, and the last image data is played for a longer time if the excess time is less than the specified time. On the other hand, if the music playback time is less than the image playback time range, if the shortage time is equal to or longer than a predetermined time, the predetermined music data is repeated for the shortage time. If the shortage time is less than the predetermined time, the slideshow playback conditions are set to play back the image data for the shortage time without music, and the home appliance data is generated according to the set playback conditions. is there.

  In a preferred embodiment of the data generation program of the present invention, the computer causes the selected quantity of still image data, the maximum and minimum values of predetermined slide intervals, and the reproduction time of moving image data as necessary. An image reproduction time calculating means for calculating a range of time (image reproduction time) during which an image based on image data is displayed, and a performance time (music reproduction time) of one or more selected music data and image reproduction A comparison means for comparing the time range, and when the music playback time exceeds or falls short of the image playback time range, and compares the excess time or shortage time with a predetermined time, and the music playback time If the image exceeds the range of the image playback time and the excess time is equal to or longer than the predetermined time, the image data is repeatedly played for the excess time, and the excess time is not In this case, the slide show playback conditions are set so that the last image data is played back for the excess time, and the music playback time is less than the image playback time range. If the time is more than the time, the music data is repeatedly played for the shortage time, and if the shortage time is less than the predetermined time, the slideshow playback conditions are set so that the image data for the shortage time is played without music. Display control means for displaying on the display means a screen for informing the comparison result between the sound reproduction time and the image reproduction time range, if necessary, To function as. Thereby, even when the relationship between the image playback time and the music playback time is not appropriate, it is possible to easily create a good-looking music slideshow in which the image and music are played back together.

  Each of the above units may be configured as hardware in the recording apparatus 1, but the computer functions as the image reproduction time calculation unit 13, the comparison unit 14, the data generation unit 15, and the display control unit 17 as necessary. The data generation program can be configured to be installed in the recording apparatus 1 and executed. 1 shows a computer device such as a personal computer as the recording device 1, the form of the recording device 1 is arbitrary. For example, the recording device 1 is installed in a store such as a photo shop or a convenience store as shown in FIG. Unmanned terminals (kiosks), dedicated set-top boxes as shown in FIG. 3, portable writers as shown in FIG. 4, DVD recorders and HDDs equipped with arithmetic processing functions as shown in FIG. As shown in FIG. 6, the recorder may be a portable device in which a terminal having a hard disk and a main body for reading and writing image data can be separated, or a car navigation device having an arithmetic processing function. it can.

  Hereinafter, a procedure of processing using the recording apparatus 1 (data generation program) having the above configuration will be described with reference to a flowchart of FIG. In the following, the case of generating data for home appliances in the Video-CD format will be described, but the present invention can also be applied to the case of generating data for home appliances in the DVD-Video format or HDTV format.

  First, in step S101, when the media 8 is loaded into the media loading unit 2 of the recording apparatus 1 or the digital camera 7 is connected to the device connection unit 3 in accordance with the instructions on the screen, the data input means 12 Image data is read from the digital camera 7 or the like. This image data is not limited to the image data obtained by photographing with the digital camera 7, but image data obtained by scanning a negative film or a photo print, moving image data obtained from a video tape recorder, or a moving image. Still image data obtained by capturing may be used, and the reading destination may be a recording medium such as a CD-R or DVD-R, or the server 10 connected via the communication network 11.

  When the reading of the image data is completed, the display control unit 17 causes the display unit 5 to display an image selection screen 19 as shown in FIG. The image selection screen 19 includes a tag display field 20 indicating a reading destination of image data, a list display field 21 for displaying a list of images based on the read image data, and a selected image display for displaying an image selected from the list. A column 22 and a work procedure display column 23 for displaying the work procedure are provided. In step S103, the user checks the images in the list display column 21 and selects image data to be used for the slide show from the images. .

  Next, in step S104, the image reproduction time calculation means 13 is based on the quantity of the selected still image data, the maximum and minimum values of the predetermined slide interval, and the reproduction time of the selected moving image data. The range of image playback time is calculated. Specifically, the maximum value (Tsmax) of the display time of the still image data is obtained by multiplying the quantity (Ns) of the selected still image data by the maximum value (dTmax) and the minimum value (dTmin) of the slide interval. ) And the minimum value (Tsmin), and the reproduction time (Tmovie) of the selected moving image data is added to each of the calculated minimum value and maximum value of the display time. The maximum value (TGmax) and the minimum value (TGmin) are calculated. The slide interval is not particularly limited. However, if the slide interval is short, images are frequently switched, and if the slide interval is long, the slide show is extended. Therefore, dTmin is about 4 seconds and dTmax is about 6 seconds. It is preferable. In addition, here, a case is shown in which both still image data and moving image data are included in the image data, but only one type of image data may be used.

TGmin = Ns × dTmin + Tmovie (1)
TGmax = Ns × dTmax + Tmovie (2)

  Next, the display control means 17 causes the display means 5 to display a BGM selection screen 24 as shown in FIG. 10, for example. On the BGM selection screen 24, a reading destination selection column 25 for selecting a reading destination of music data, a list display column 26 for displaying the title name, artist name, performance time, etc. of the music data, and the selected music data are confirmed. A selection music display field 27 to be performed, a work procedure display field 23 indicating a work procedure, and the like are provided, and a frame of the selected image data is displayed at a predetermined position on the BGM selection screen 24 (here, above the list display field). Reference information 28 such as the number and the range of image reproduction time is displayed. In step S105, the user refers to the reference information 28, selects one or a plurality of music data from the list display field 26, displays the selected music data in the selected music display field 27, and listens to the selected music data. Then, the music data to be used as the slide show BGM is determined.

  The description content of the reference information 28 is not limited, and information that can be used when music data is selected may be displayed. For example, only the quantity of image data may be displayed, or only the range of the image reproduction time. Or a time obtained by adding or subtracting a predetermined margin to the image reproduction time may be displayed. The format of the music data is not particularly limited, and data in any format such as WAV, MP3 (MPEG Audio Layer-3), AAC (Advanced Audio Coding), ATRAC (Adaptive TRansform Acoustic Coding), CD-Track, etc. is used. can do.

  Here, if the user refers to the reference information 28 and always selects the music data of the performance time within the range of image reproduction time (TGmin to TGmax), the home appliance is based on the selected image data and music data. For example, when music data having a performance time within the range of the image playback time is not displayed in the list display field 26 of the BGM selection screen 24, or when the performance time is outside the range of the image playback time. If the music data is selected, the performance time of each music data is within the image playback time range, but if the total performance time exceeds the image playback time range, It becomes impossible to realize a slide show that is played as a unit.

  Therefore, in this embodiment, even when music data having a performance time outside the range of the image playback time is selected, slide show data in which images and music are played together can be created. As described above, in step S106, the comparison unit 14 acquires the performance time (music reproduction time: TM) of one or more music data selected with reference to the header information of the music data, and the music reproduction time. Is compared with the range of image reproduction time (TGmin to TGmax), and reproduction of image data and music data in the slide show is controlled based on the comparison result as described later.

  At that time, in order to notify the user that the reproduction of the image data and the music data is controlled, the display control means 17 may display the notification screen 29 as shown in FIG. Good. It is preferable that information based on the comparison result in the comparison unit 14 is displayed on the notification screen 29. For example, when the music playback time exceeds the range of the image playback time, FIG. When the music playback time is less than the image playback time range, a notification screen 29 as shown in FIG. 11B is displayed. Then, the user looks at the notification screen 29, presses a “return” button or the like as necessary, returns to step S103 or S105, and again selects image data or music data. When the music playback time is within the image playback time range, a notification screen 29 as shown in FIG. 11C may be displayed to notify the user that the music data is appropriate.

  Then, after displaying the notification screen 29 as necessary, in step S107, if the music playback time is within the range of the image playback time, the process skips to step S115 to start generation of home appliance data, and the music playback time Is not within the range of the image playback time, it is determined whether or not the music playback time exceeds the range of the image playback time in step S108, and if it exceeds, the processing of steps S109 to S111 is executed. Is less than the image reproduction time range, the processing of steps S112 to S114 is executed. Hereinafter, a specific description will be given with reference to FIGS. 12 and 13. 12 and 13 show the case where 1 to n still image data are selected, and the rectangular frame of each image shows a frame image.

  First, when the music playback time exceeds the range of the image playback time, in step S109, the comparison unit 14 calculates the maximum value (TGmax) of the image playback time from the music playback time (TM). Subtracted time) is calculated, and it is determined whether the excess time is equal to or longer than a predetermined time. The predetermined time is not particularly limited, but as described later, it is preferable to set the time so that the user does not feel that the last image data is extended when the last image data is reproduced for a long time. It can be about a second.

  If the excess time is equal to or longer than the predetermined time, in step S110, the data generation unit 15 adds the amount of still image data (or the movie data if the movie data is included) to the excess time by dividing the excess time by the slide time. The playback condition of the slide show is set and stored in the storage means 18 so as to repeatedly play back the time obtained by subtracting the playback time of the video data from the time and divided by the slide time, and the excess time is a predetermined time. If it is less, in step S111, the data generation means 15 reproduces the last image data longer by the excess time (if the last image data is movie data, the last frame of the movie data is displayed longer). The slide show reproduction conditions are set in the storage means 18 and stored in the storage means 18. In addition, the reproduction order of the image data when the image data is reproduced repeatedly is arbitrary, and the image data may be reproduced repeatedly while maintaining the first reproduction order, or the randomly selected image data is reproduced. Also good. In addition, the slide interval under the above reproduction conditions can be any time in the range of TGmin to TGmax, but the excess time is the time obtained by subtracting the maximum value (TGmax) of the image reproduction time from the music reproduction time (TM). In this case, it is preferable to use the maximum value (dTmax) of the slide interval. When the slide interval is changed, the excess time may be calculated based on the image reproduction time calculated from the changed slide interval.

  The slide show set by the above method is schematically shown in FIG. 12, and when the excess time is equal to or longer than the predetermined time, the last image data (image n) is displayed as shown in FIG. Later, the displayed image data images are displayed in a predetermined order (in this case, in order from the first image data image (image 1)), and the excess time is less than the predetermined time, as shown in FIG. As described above, the image (image n) of the last image data is displayed until the reproduction of the music data is completed (that is, a screen shown by shading is added).

  On the other hand, if the music playback time is less than the range of the image playback time, the comparison unit 14 subtracts the minimum value (TGmin) of the image playback time from the music playback time (TM) in step S112. Time) is calculated, and it is determined whether the shortage time is equal to or longer than a predetermined time. Although the predetermined time is not particularly limited, as described later, it is preferable to set the time so that the user does not feel uncomfortable when the image data for the shortage time is reproduced without music. can do. Note that the predetermined time compared in step S109 and the predetermined time compared in step S112 may be the same or different.

  If the shortage time is equal to or longer than the predetermined time, in step S113, the data generation means 15 sets the slideshow playback conditions so that music data is repeatedly played back for the shortage time, and stores it in the storage means 18. If the shortage time is less than the predetermined time, in step S114, the data generation means 15 sets the playback conditions for the slide show so as to play back the image data for the shortage time without music, and stores it in the storage means 18. When music data is repeatedly played, the music data may be stopped when the shortage time has elapsed, or may be faded out so that the volume gradually decreases before the shortage time elapses. Good. Further, when a plurality of music data is selected, any music data may be repeatedly played, for example, the music data played first may be played, or the music having the performance time closest to the shortage time Data may be played back. Also, the slide interval under the above reproduction conditions can be any time in the range of TGmin to TGmax, but the shortage time is the time obtained by subtracting the minimum value (TGmin) of the image reproduction time from the music reproduction time (TM). In this case, it is preferable to use the minimum value (dTmin) of the slide interval. When the slide interval is changed, the shortage time may be calculated based on the image reproduction time calculated from the changed slide interval.

  A slide show set by the above method is schematically shown in FIG. 13, and when the shortage time is equal to or longer than a predetermined time, as shown in FIG. When one or a plurality of reproduced music data (here, BGM1) is reproduced and the shortage time is less than the predetermined time, as shown in FIG. Part of n-1 and image n) are displayed without music.

  Next, in step S115, the data generation unit 15 reads out the slide show reproduction conditions stored in steps S110, 111, 113, and 114 from the storage unit 18, and selects the selected image data (still image data and / or moving image data). ) And the selected one or more music data, the home appliance data is generated based on the reproduction condition. Specifically, first, difference data based on the slide effect for the slide interval (data of difference 0 when the same image is displayed for a certain period of time) is added to each still image data, and a predetermined format (here MPEG1 format video data is created, music data is synthesized with this video data, and MPEG1 format video data synthesized with the music data is reproduced in a format that can be played back by home appliances (for example, CD-R format). In the case of Video-CD format, DVD-R format in the case of DVD-R, and HDTV format data in the case of a Blu-ray disc).

  Thereafter, in step S116, a recording medium 9 such as a CD-R / RW, a DVD ± R / RW, a DVD-RAM, or a Blu-ray disc is loaded into the recording medium loading unit 4 of the recording apparatus 1. Although any commercially available recording medium can be used as the recording medium 9, data may be recorded only on a specific recording medium 9. The recording medium 9 can be identified based on whether or not identification information for identifying the recording medium 9 is recorded in this area. The content of the identification information is not limited, but if the contents of the identification information are easily known, the identification information itself is also copied. Therefore, 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, information by guide groove modulation (ATIP: Absolute Time In Pre-groove) given at the time of CD-R molding, and the like are preferable.

  Here, the structure of a general recording medium 9 (CD-R) 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. A reflective layer 102 made of silver or the like 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 form pits. Recording is performed, but the laser power has an optimum value 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 drive side needs to recognize the recommended type of R type and laser recording power. Therefore, information such as the disc application code and recommended laser recording power is written as information by guide groove modulation (ATIP) at the recording medium manufacturing stage, and this 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. Further, lead-in start time, maximum lead-out startable time, etc., which are guide groove modulation (ATIP) other than the above, can be used as identification information by appropriately setting.

  Next, the image data input to the recording medium 9 and the generated home appliance data are recorded. At this time, since the recording area in which the home appliance can read the data is limited, in step S117, the data The recording unit 16 writes the home appliance data on the inner peripheral side of the logical address area of the recording medium 9. The logical address area is an area in which user data (program) is recorded, such as a program memory area in which user data arrangement information is recorded, a lead-in / TOC (Table Of Contents) area, and a lead-out area. Does not include the information area, the application code of the disc, the recommended value of laser recording power, and the area of guide groove modulation (ATIP) information in which other information is recorded. Shall be pointed to.

  Next, after closing the session as necessary, in step S118, the data recording unit 16 uses the data for computer equipment such as the selected still image data and music data recorded on the tip of the recording medium 9 for home appliances. Write outside the data.

  The directory structure of the recording medium 9 created by the above procedure is, for example, as shown in FIG. 14A, and a file (Slidesetting.ini) describing image data, music data, a slide show playback program, and slide show playback conditions. The computer device data is composed of an information file in which various information related to the recording medium 9 is described, and the image data associated with the video data in the “VCD” folder as a Video-CD format is displayed on the TV screen in the “SEGMENT” folder. Home appliance data is composed of image data to be displayed, moving image data in the “MPEGAV” folder, an application for displaying still image data on the TV screen in the “CDI” folder, and the like. Further, the directory structure of the recording medium 9 (DVD-R) is as shown in FIG. 14B, for example, and the home appliance data includes the video manager (VMG) and the video title set (in the “VIDEO_TS” folder). VTS) constitutes home appliance data (DVD-Video data). More specifically, the VMG is composed of VIDEO_TS.IFO in which information for controlling the entire video is recorded, VIDEO_TS.BUP that 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

  Although the directory structure of the image data is arbitrary, in order to facilitate management when the image data is backed up to a computer device or the like, for example, as shown in FIG. Folder indicating the storage location of image data for each media 8, device, and film in the lower hierarchy of PS_Roll (ROYYMMDDyyy_XXXXXXAABxxx, YYMMDD: Number specifying the date of writing, yyy: Sequential number for each day, XXXXXX: Random ID number, AA: Manufacturer code (00 to ZZ), B: Software, product category (0 to Z), xxx: Sequential number), etc., and each image data is CCYYMMDDxxxxxx (CC: Image data Type, YYMMDD: Number specifying the date of writing, xxxxxx: Sequential number), etc. can be renamed.

  As described above, in this embodiment, when image data to be reproduced in a slide show is selected, an image is selected based on the number of still image data, the maximum and minimum values of predetermined slide intervals, and the reproduction time of moving image data. When a playback time range is calculated and one or more music data to be used as a slide show BGM are selected with reference to the image playback time range, the music data performance time (music playback time) and image playback time are selected. If necessary, a notification screen 29 showing the comparison result is displayed on the display means 5, and if the music playback time exceeds the image playback time range, the excess time is a predetermined time or more. If so, the slideshow is replayed so that the last image data is displayed longer for the excess time if the excess time is less than the predetermined time. If conditions are set and the music playback time is less than the image playback time range, if the shortage time is equal to or longer than the predetermined time, the music data is repeatedly played for the shortage time, and if the shortage time is less than the predetermined time Slideshow playback conditions are set so that image data for the shortage time is displayed without music, so it is easy to create a great-looking slideshow with music that plays back images and music together. it can.

  In the above embodiment, the case of generating data for playing back a slide show on a home appliance has been described. However, the present invention is not limited to the above embodiment, and the slide show is played on a computer device. The present invention can also be applied to the case of generating data describing playback conditions.

  The present invention can be applied to a program for generating data for simultaneously reproducing any kind of image data and any kind of music data, and an apparatus and a method capable of executing the program.
