Here, the asset roll directory making unit 215 may make the asset roll directory 310 to have a directory name distinguishing each of the asset roll directories 310 of each of a plurality of recording mediums. Specifically, the asset roll directory making unit 215 may determine a directory name different for each apparatus identifier on the basis of the apparatus identifier received from the apparatus identifier acquiring unit 205. Further, on the basis of the date and/or time at which the asset roll directory 310 is generated received from the date and/or time acquiring unit 210, the asset roll directory making unit 215 may determine the directory name different for each date and/or time. Further, the asset directory 300 storing the asset roll directory 310 is determined for the asset roll directory making unit 215 according to the predetermined format of the recording medium 30. In case the asset directory does not exist in the recording medium 30, it is possible to make the asset roll directory 310 after making the asset directory 300. Then, the asset roll directory making unit 215 outputs a path to the asset roll directory 310 which is made for the recording medium 30 to the display image directory making unit 225 and the asset recording unit 235.
The display image generating unit 220 generates the plurality of display images 318 by decreasing the resolution of the plurality of digital assets 312 input by the image inputting unit 200. Here, for each of the plurality of display images 318, the display image generating unit 220 may generate a file name of the display image 318 by transforming the file name of the digital asset 312 used when the display image 318 is generated by a predetermined rule which is inverse-transformable. Specifically, for each of the plurality of display images 318, the display image generating unit 220 may generate the file name of the display image 318 by changing a leading character string of a predetermined length of the file name of the digital asset 312 used when the display image 318 is generated to a different character string. Here, the file name of each of the digital assets 312 may be a file name determined by the image inputting unit 200 while the digital asset 312 is input. Then, the display image generating unit 220 outputs the plurality of display images 318 to the display image recording unit 240. Further, the display image generating unit 220 outputs the file name of each of the plurality of the display images 318 to the asset manifest generating unit 230.
The display image directory making unit 225 makes the display image directory 316 storing the plurality of display image 318 generated by the display image generating unit 220 in a lower level of the asset roll directory 310 made by the asset roll directory making unit 215. Then, the display image directory making unit 225 outputs a path to the display image directory 316 to the display image recording unit 240. Further, the display image directory making unit 225 outputs the path to the display image directory 316 and the path to the asset roll directory 310 to the asset manifest generating unit 230.
The asset manifest generating unit 230 generates the asset manifest file 314 storing the path to each of the plurality of digital assets 312 in case the plurality of digital assets 312 input by the image inputting unit 200 are recorded on the recording medium 30 and the path to each of the plurality of display images 318 in case the plurality of display images 318 generated by the display image generating unit 220 are recorded on the recording medium 30. Here, the asset manifest generating unit 230 may detect the path to each of the plurality of digital assets 312 and the path to each of the plurality of display images 318 on the basis of a predetermined positional relationship between the asset manifest file 314 and the asset roll directory 310, for example, that the asset manifest file 314 is stored right under the asset roll directory 310. Then, the asset manifest generating unit 230 may detect the path to each of the plurality of digital assets 312 on the basis of the file name of each of the plurality of digital assets 312 input from the image inputting unit 200 and a predetermined positional relationship between the plurality of digital assets 312 and the asset roll directory 310, for example, that the plurality of digital assets 312 is stored right under the asset roll directory 310. Further, the asset manifest generating unit 230 may detect the path to each of the plurality of display images 318 on the basis of the file name of each of the plurality of display images 318 received from the display image generating unit 220, the path to the display image directory 316 and the path to the asset roll directory 310 received from the display image directory making unit 225. Then, the asset manifest generating unit 230 outputs the generated asset manifest file 314 to the asset recording unit 235.
The asset recording unit 235 records the plurality of digital assets 312 received from the image inputting unit 200 and the plurality of asset manifest file 314 received from the asset manifest generating unit 230 on the recording medium 30 so as to be recorded in the asset roll directory 310 made by the asset roll directory making unit 215. Then, the asset recording unit 235 outputs the path to the recorded asset manifest file 314 and the image identifier for identifying each of the plurality of digital assets 312 recorded to the album generating manifest generating unit 250. Further, the asset recording unit 235 outputs the path to the recorded asset manifest file 314 to the index generating unit 260. The display image recording unit 240 records the plurality of display images 318 generated by the display image generating unit 220 on the recording medium so as to be recorded in the display image directory 316 made by the display image directory making unit 225.
The album directory making unit 245 makes the album directory 330 storing the album manifest file 332 in a position which is not a lower level of the asset roll directory 310 made by the asset roll directory making unit 215. For example, the album directory making unit 245 may make the album directory 330 to be stored in the root directory of the recording medium 30. Then, the album directory making unit 245 outputs a path to the made album directory 330 to the album manifest recording unit 255.
The album manifest generating unit 250 generates the album manifest file 332 storing the path to the asset manifest file 314 recorded on the recording medium 30 and a displaying order in case the plurality of digital assets 312 recorded on the recording medium 30 are displayed. Specifically, the album manifest generating unit 250 may store the image identifier for identifying the digital asset 312 in the album manifest file 332 correspondingly to the displaying order. Then, the album manifest generating unit 250 outputs the generated album manifest file 332 to the album manifest recording unit 255. The album manifest recording unit 255 records the album manifest file 332 generated by the album manifest generating unit 250 on the recording medium 30 to be stored in the album directory 330 made by the album directory making unit 245. Then, the album manifest recording unit 255 outputs the path to the recorded album manifest file 332 to the index generating unit 260.
The index generating unit 260 generates the index manifest file 340 storing the path to the asset manifest file 314 recorded on the recoding medium 30 by the asset recording unit 235 and the path to the album manifest file 332 recorded on the recording medium 30 by the album manifest recording unit 255. Then, the index generating unit 260 outputs the generated index manifest file 340 to the index recording unit 265. The index recording unit 265 records the index manifest file 340 generated by the index generating unit 260 on a predetermined path which is not varied according to the recording medium 30.
According to the image recording apparatus 20 of the present embodiment, it is possible to set the directory name different for each of the plurality of recording mediums to the directory name of the asset roll directory 310. Thus, in case of copying the asset roll directory 310 recorded on the recording medium 30 to another recording medium and memory apparatus, it is possible to prevent the asset roll directory 310 previously stored in said another recording medium and memory apparatus from being overwritten. Accordingly, it is possible to prevent a file stored in said another recording medium and memory apparatus from being removed without intention.
Further, it is possible to prevent the directory name of the asset roll directory 310 from being duplicated for a recording medium 30 recorded by different image recording apparatus 20 by determining the name of the directory name of the asset roll directory 310 on the basis of the apparatus identifier such as the MAC address. Further, it is possible to prevent the directory name of the asset roll directory 310 from being duplicated for a plurality of recording mediums 30 recorded by the same image recording apparatus 20 by determining the directory name of the asset roll directory 310 on the basis of the date and/or time at which the asset roll directory 310 is made.
Further, the asset roll directory 310 is copied to another recording medium by making the display image directory 316 in a lower level of the asset roll directory 310. Thus, it is possible to copy the digital asset 312 stored in the asset roll directory 310 and the display image 318 generated from the digital asset 312 collectively. Thus, it becomes easy to manage image data recorded on the recording medium 30.
Further, by transforming the file name of the digital asset by a rule which is inverse-transformable to generate the file name of the display image 318, it is possible to detect a corresponding relationship between the digital asset 312 and the display image 318 even in case the asset manifest file 314 is lost, for example. In addition, it is possible detect a corresponding relationship between the digital asset 312 and the display image 318 with a simple configuration and a short time by changing the leading character string of the file name of the digital asset 312 to another character string to generate the file name of the display image 318.
The index retrieving unit 400 retrieves the index manifest file 340 from the recording medium 30. Here, the index retrieving unit 400 is not varied according the recording medium 30 and may retrieve the index manifest file 340 by using a predetermined path. Then, the index retrieving unit 400 outputs the retrieved index manifest file 340 to the album manifest retrieving unit 410. The album manifest retrieving unit 410 retrieves the album manifest file 332 from the recording medium 30 by using the path to the album manifest file 332 which is stored in the index manifest file 340 retrieved by the index retrieving unit 400. Then, the album manifest retrieving unit 410 outputs the retrieved album manifest file 332 to the asset manifest retrieving unit 420. The asset manifest retrieving unit 420 retrieves the asset manifest file 314 from the recording medium 30 by using the path to the asset manifest file 314 which is stored in the album manifest file 332 retrieved by the album manifest retrieving unit 410. Then, the asset manifest retrieving unit 420 outputs the retrieved asset manifest file 314 to the image retrieving unit 430.
The image retrieving unit 430 retrieves at least a part of the plurality of digital assets 312 from the recording medium 30 by using the path to each of the plurality of digital assets 312 which is stored in the asset manifest file 314 retrieved by the asset manifest retrieving unit 420. Further, the image retrieving unit 430 may retrieve at least a part of the plurality of display images 318 from the recording medium 30 by using the path to each of the plurality of display images 318 which is stored in the asset manifest file 314, instead of retrieving the digital asset 312. Specifically, the image retrieving unit 430 retrieves the display image 318 in case the path to the display image generated from the digital asset is stored in the asset manifest file sequentially or retrieves the digital asset 312 in case the path to the display image 318 generated from the digital asset 312 is not stored in the asset manifest file, for each of the digital assets 312 which should be displayed according to the displaying order determined by the album manifest file 332 retrieved by the album manifest retrieving unit 410. Then, the output unit 440 displays the digital asset 312 or the display image 318 retrieved by the image retrieving unit 430. It is to be understood that the output unit 440 may also provide audio and printed output.
According to the image retrieving apparatus 40 of the present embodiment, since the path to the index manifest file 340 in which the path to the asset manifest file 314 is stored is determined regardless of the format of the recording medium, it is possible to accurately retrieve the asset manifest file 314 even in case the path to the asset manifest file 314 is varied according to the format of the recording medium. Thus, it is possible to accurately retrieve each of the plurality of digital assets 312 on the basis of the retrieved asset manifest file 314 even in case a region on which the plurality of digital assets 312 are recorded, that is, the path to each of the digital assets is different for each recording medium.
Further, in case the resolution of the output unit 440 is lower than that of the digital asset 312, a large part of the information of the digital asset 312 is not displayed and the time taken to retrieve the data and memory are wasted. However, according to the image retrieving apparatus 40 of the present embodiment, since the display image 318 of which resolution is lower that that of the digital asset 312 is previously recorded on the recording medium 30, it is possible to perform image retrieval and display efficiently and at high speed by retrieving and displaying the display image 318 corresponding to the digital asset 312 instead of the digital asset 312. Further, since the path to the display image 318 is stored in the asset manifest file 314, it is possible to accurately retrieve the display image 318 even in case the path to the display image 318 is varied according to the format of the recording medium 30.
Further, since the path to the album manifest file 332 is stored in the index manifest file 340, it is possible to accurately retrieve the digital asset 312 and the display image 318 even in case the path to the album manifest file 332 is varied according to the format of the recording medium 30.
Furthermore, the image retrieving apparatus 40 may display the digital asset 312 or the display image 318 regardless of the album manifest file 332. In this case, the image retrieving apparatus 40 may not include the album manifest retrieving unit 410 and the asset manifest retrieving unit 420 may retrieve the asset manifest file 314 by using the path to the asset manifest file 314 stored in the index manifest file 340 instead of the album manifest file 332.
In addition, the image retrieving apparatus 40 may not include the image display. In this case, the image retrieving apparatus 40 may provide the user with the digital asset 312 by, for example, printing the digital asset 312 retrieved by the image retrieving unit 430. Further, the image retrieving apparatus 40 may output the digital asset 312 or the display image 318 retrieved by the image retrieving unit 430 to a display apparatus remote from the image retrieving unit 430 via a network connection.
Then, the asset manifest generating unit 230 generates the asset manifest file 314 which stores the path to each of the plurality of digital assets 312 in case the plurality of digital assets input 312 are recorded on the recording medium 30 and the path to each of the plurality of digital assets 312 in case the plurality of display images generated 318 are recorded on the recording medium 30 (S1040). The asset recording unit 235 records the plurality of digital assets input 312 and the generated asset manifest file 314 on the recording medium so as to be stored in the made asset roll directory 310 (S1050) The display image recording unit 240 records the plurality of display image generated 318 on the recording medium 30 so as to be stored in the made display image directory 316 (S1060)
Then, the album directory making unit 245 makes the album directory 330 in which the album manifest file 332 is stored in a position which is not a lower level of the made asset roll directory 310 (51070). The album manifest generating unit 250 generates the album manifest file 332 which stores the path to the asset manifest file 314 recorded on the recording medium 30 and the displaying order of the plurality of digital assets 312 recorded on the recording medium 30 (S1080). The album manifest recording unit 255 records the generated album manifest file 332 on the recording medium 30 so as to be stored in the made album directory 330 (S1090).
Then, the index generating unit 260 generates the index manifest file 340 which stores the path to the asset manifest file 314 recorded on the recording medium 30 and the path to the album manifest file 332 recorded on the recording medium 30 (S1100) The index recording unit 265 records the generated index manifest file 340 on a predetermined path which is not different for each recording medium 30 (S1110).
According to the image recording apparatus 20 of the present embodiment, it is possible to make the album directory 330 in a position which is not a lower level of the asset roll directory 310. Thus, in case of using the album manifest file 332 determining a displaying order of images over a plurality of asset roll directories 310, it is not necessary to move the album manifest file 332 even if the asset roll directory 310 is deleted from the recording medium 30.
Then, the image retrieving apparatus 40 repeats the following processes for the digital asset(s) 312 which are determined to bed is played by the album manifest file 332 (S1230) The image retrieving unit 430 determines whether or not the path to the display image 318 generated from the digital asset 312 is stored in the asset manifest file 314 (S1240). For example, the image retrieving unit 430 determines whether or not the path to the display image 318 corresponding to the image identifier for identifying the digital asset 312 is stored in the asset manifest file 314. In case the path to the display image 318 is stored in the asset manifest file 314 (S1240: Yes), the image retrieving unit 430 retrieves the display image 318 by using the path to the display image 318 (S1250).
On the other hand, in case the path to the display image 318 is not stored in the asset manifest file 314 (S1240: No), the image retrieving unit 430 retrieves the digital asset 312 by using the path to the digital asset 312 stored in the asset manifest file 314 (S1260). Then, the image retrieving unit 430 decreases the resolution of the retrieved digital asset 312 according to the resolution of the image display unit 440 (31270).
Then, the image display unit 440 displays the retrieved display image 318 or the digital asset 312 which is retrieved and of which resolution is decreased (S1280). Here, in case the user instructs to print the displayed image by using an input means provided in the image retrieving apparatus 40, the image retrieving apparatus 40 may retrieve the digital asset 312 from the recording medium 30 and outputs it to a printing means of the image retrieving apparatus 40 or an external printing apparatus. Then, the image retrieving apparatus 40 repeats the above processes for all digital assets which are to be displayed, presented and/or output.
The image inputting unit 200 inputs a plurality of new digital assets 312 (31400). The index retrieving unit 400 retrieves the index manifest file 340 previously recorded from the recording medium 30 (S1410). The album manifest retrieving unit 410 retrieves the album manifest file 332 previously recorded from the recording medium 30 by using the path to the album manifest file 332 stored in the retrieved index manifest file 340 (S1420). The asset roll directory making unit 215 makes a new asset roll directory 310 storing the plurality of new digital assets input 312 in the recording medium 30 to have a directory name distinguishing each of the asset roll directories 310 of each of a plurality of recording mediums (31430). The display image directory making unit 225 makes a new display image directory storing a plurality of display images in a lower level of the new asset roll directory 310 (S1440). The display image generating unit 220 generates the plurality of new display images 318 by decreasing resolution of the plurality of digital assets input 312 (S1450).
The asset manifest generating unit 230 generates a new asset manifest file 314 which stores a path to each of the plurality of new digital assets 312 in case the plurality of new digital assets input 312 are recorded on the recording medium 30 and a path to each of the plurality of new display images 318 in case the plurality of new display images generated 318 are recorded on the recording medium 30. The asset recording unit 235 records the plurality of new digital assets 312 and the new asset manifest file generated 314 on a region of the recording medium on which information is not recorded yet so as to be stored in the new asset roll directory made 310 (S1470) The display image recording unit 240 records the plurality of new display images generated 318 on a region of the recording medium on which information is not recorded yet so as to be stored in the new display image directory made 316 (S1480).
The album manifest generating unit 250 generates a new album manifest file 332 by storing further a path to the new asset manifest file made 314 and a displaying order in case the plurality of new digital assets input 312 are displayed in the album manifest file 332 previously recorded on the recording medium 30 (31490). The album manifest recording unit 255 nullifies the album manifest file 332 recorded on the recording medium 30 (S1500). The album manifest recording unit 255 records the new album manifest file generated 332 on a region of the recording medium on which information is not recorded yet (S1510) For example, the album manifest recording unit 255 may record the new album manifest file 332 on the recording medium 30 with the same path as the album manifest file 332 previously recorded. Further, the album manifest recording unit 255 may record file management information that a physical region of the recording medium corresponding to the path to the album manifest file 332 is changed from a physical region of the album manifest file 332 previously recorded to a physical region of the new album manifest file 332, on the recording medium 30.
In case the new digital asset 312 is additionally recorded on the write-once type recording medium on which the digital asset 312 is previously recorded, if a slideshow is recorded as a video stream, it is needed to generate the video stream once again and record it. Since a data amount of a video stream is large than that of a still picture generally, the generated video stream cannot be recorded on the recording medium on which a video stream is already recorded and thus sometimes it should be recorded on a new recording medium. However, according to the image recording apparatus 20 of the present embodiment, it is possible to make the recording medium for displaying a slideshow to which the new digital asset 312 is added by only recording the new digital asset 312 and simultaneously updating the new album manifest file 332. Thus, it is possible to use the recording area of the recording medium 30 efficiently. Further, since the process of recording the plurality of digital assets 312 and updating the album manifest file 332 can be performed in a short time in comparison with a process of generating and recording a video stream, it is possible to improve convenience of the user in case of adding a plurality of new digital assets by using the image recording apparatus 20 of the present embodiment.
The recording apparatus 70 of the present embodiment includes a first index retrieving unit 700, a first asset directory detecting unit 705, an asset manifest retrieving unit 710, an image retrieving unit 715, a second index retrieving unit 720, a second asset directory detecting unit 725, an asset directory making unit 730, an asset roll directory making unit 735, an asset recording unit 740, an index generating unit 745, and an index recording unit 750.
The first index retrieving unit 700 retrieves the index manifest file 340 from the first recording medium 60. Here, the first index retrieving unit 700 is not different for each first recording medium 60 and may retrieve the index manifest file 340 by using a predetermined path. Then, the first index retrieving unit 700 outputs the retrieved index manifest file 340 to the first asset directory detecting unit 705 and the asset manifest retrieving unit 710.
The first asset directory detecting unit 705 detects a directory name of the asset directory 300 including the asset roll directory 310 stored in the first recording medium 60 on the basis of a path to the asset manifest file 314 stored in the index manifest file 340 retrieved by the first index retrieving unit 700. Here, the first asset directory detecting unit 705 may detect that the asset directory 300 does not exist in case the first recording medium 60 does not include the asset roll directory 300 and includes the asset roll directory 310 right under the root directory. The first asset directory detecting unit 705 outputs the path to the asset manifest file 314 of the first recording medium 60 and the detected directory name of the asset directory 300 to the asset directory making unit 730, the asset roll directory making unit 735, and the asset recording unit 740.
The asset manifest retrieving unit 710 retrieves the asset manifest file 314 from the first recording medium 60 by using the path to the asset manifest file 314 stored in the index manifest file 340 retrieved by the first index retrieving unit 700. Then, the asset manifest retrieving unit 710 outputs the retrieved asset manifest file 314 to the image retrieving unit 715 and the asset recording unit 740. The image retrieving unit 715 retrieves the plurality of digital assets 312 from the first recording medium 60 by using a path to each of the plurality of digital assets 312 stored in the asset manifest file 314 retrieved by the asset manifest retrieving unit 710. Then, the image retrieving unit 715 outputs the plurality of digital assets retrieved 312 to the asset recording unit 740.
The second index retrieving unit 720 retrieves the index manifest file 340 from the second recording medium 80. Here, the second index retrieving unit 720 is not different for each second recording medium 80 and may retrieve the index manifest file 340 by using a predetermined path. Then, the second index retrieving unit 720 outputs the retrieved index manifest file 340 to the second asset directory detecting unit 725 and the index generating unit 745.
The second asset directory detecting unit 725 detects a directory name of the asset directory 300 including the asset roll directory 310 stored in the second recording medium 80 on the basis of a path to the asset manifest file 314 stored in the index manifest file 340 retrieved by the second index retrieving unit 720. Here, the second asset directory detecting unit 725 may detect that the asset directory 300 does not exist in case the second recording medium 80 does not include the asset roll directory 300 and includes the asset roll directory 310 located under the root directory. The second asset directory detecting unit 725 outputs the detected directory name of the asset directory 300 to the asset directory making unit 730, the asset roll directory making unit 735, and the asset recording unit 740.
The asset directory making unit 730 makes the asset directory 300 of a predetermined name in the second recording medium 80 in case the directory names of the asset directory 300 detected by the first and second asset directory detecting units 705 and 725 are not the same. Then, the asset directory making unit 730 outputs a path to the made asset directory 300 to the asset roll directory making unit 735.
The asset roll directory making unit 735 makes the asset manifest file 314 retrieved by the asset manifest retrieving unit 710 and the asset roll directory 310 which should store the plurality of digital assets 312 retrieved by the image retrieving unit 715 in the second recording medium 80. Specifically, the asset roll directory making unit 735 makes the asset roll directory 310 in a lower level of the asset directory 300 of the second recording medium 80 in case the directory names of the asset directory 300 detected by the first and second asset directory detecting units 705 and 725 are the same. Further, the asset roll directory making unit 735 makes the asset roll directory 310 in a lower level of the asset directory 300 made by the asset directory making unit 730 of the second recording medium 80 in case the directory names of the asset directory 300 detected by the first and second asset directory detecting units 705 and 725 are not the same. In addition, the asset roll directory making unit 735 may determine a directory name of the asset roll directory 310 to be made on the basis of the path to the asset manifest file 314 of the first recording medium 60 received from the first asset directory detecting unit 710 so that the asset manifest file 314 have the same directory name as that of the asset roll directory 310 stored in the first recording medium 60. Then, the asset roll directory making unit 735 outputs the path to the made asset roll directory 310 to the asset recording unit 740.
The asset recording unit 740 records the asset manifest file 314 recorded on the first recording medium 60 retrieved by the asset manifest retrieving unit 710 and the plurality of digital asset 312 recorded on the first recording medium 60 retrieved by the image retrieving unit 715 on the second recording medium 80 so as to be stored in the asset roll directory 310 made by the asset roll directory making unit 735. The asset recording unit 740 outputs the path to the recorded asset manifest file 314.
The index generating unit 745 generates a new index manifest file 340 by storing further the path to the asset manifest file 314 recorded by the asset recording unit 740 on the second recording medium 80 in the index manifest file 340 which is previously recorded on the second recording medium and retrieved by the second index retrieving unit 720. Then, the index generating unit 745 outputs the new index manifest file generated 340 to the index recording unit 750.
The index recording unit 750 updates the index manifest file 340 which is previously recorded on the second recording medium 80 by using the new index manifest file 340 generated by the index generating unit 745. For example, in case the second recording medium 80 is a write-once type, the index recording unit 750 may nullify the index manifest file 340 previously recorded and record the new index manifest file 340 on a region on which information is not recorded yet.
According to the image recording apparatus 70 of the present embodiment, it is possible to record the plurality of digital assets 312 recorded on the first recording medium 60, which is a recording medium other than the second recording medium 80, additionally on the second recording medium 80 on which the digital asset 312 is previously recorded. Further, according to the image recording apparatus 70, in case each recording medium is based on the same format, it is possible to record the plurality of digital assets 312 and the asset manifest file 314 of the first recording medium 60 without changing the path to the plurality of digital assets 312 and the asset manifest file 314 of the first recording medium 60. Further, according to the image recording apparatus 70, in case each recording medium is based on a different format from each other, it is possible to make the asset directory 300 of a predetermined directory name and record the plurality of digital assets 312 and the asset manifest file 314 on the second recording medium 80. Therefore, according to the recording apparatus 70, it is possible to copy the digital asset 312 from the first recording medium 60 to the second recording medium 80 and vice versa regardless of the format of the first and second recording mediums 60 and 80.
The image recording apparatus 70 shown in the present figure records the plurality of digital assets 312 and the asset manifest file 314 recorded on the first recording medium on the second recording medium 80. In addition, the image recording apparatus 70 may further record the album manifest file 332 recorded on the first recording medium 60 on the second recording medium 80. In this case, the recording apparatus 70 may update the album manifest file 332 so that the path to the asset manifest file 314 and the displaying order of the plurality of digital assets 312 recorded by the asset recording unit 740 are further stored in the album manifest file 332 previously recorded on the second recording medium 80. Instead, the recording apparatus 70 may record a new album manifest file 332 storing the path to the asset manifest file 314 and the displaying order of the plurality of digital assets 312 recorded by the asset recording unit 740 independently from the album manifest file 332 previously recorded on the second recording medium 80.
The second index retrieving unit 720 retrieves the index manifest file 340 from the second recording medium 80 (S1640). The second asset directory detecting unit 725 detects the directory name of the asset directory 300 including the asset roll directory 310 stored in the second recording medium 80 on the basis of the path to the asset manifest file 314 stored in the index manifest file 340 retrieved by the second index retrieving unit 720 (S1650).
Then, the image recording apparatus 70 determines whether or not the directory names of the asset directory 300 detected by the first and second asset directory detecting units 705 and 725 are the same (S1660). In case the directory names of the asset directory 300 are not the same (S1660: No), the asset directory making unit 730 makes the asset directory 300 of a predetermined name in the second recording medium 80 (S1670)
Then, the asset roll directory making unit 735 makes the asset manifest file 314 retrieved by the asset manifest retrieving unit 710 and the asset roll directory 310 which should store the plurality of digital assets 312 retrieved by the image retrieving unit 715 in the second recording medium 80 (S1680). The asset recording unit 740 records the asset manifest file 314 which is recorded on the first recording medium 60 and retrieved by the asset manifest retrieving unit 710 and the plurality of digital assets 312 which are recorded on the first recording medium 60 and retrieved by the image retrieving unit 715 on the second recording medium 80 so as to be stored in the asset roll directory 310 made by the asset roll directory making unit 735 (S1690).
The index generating unit 745 generates a new index manifest file 340 by storing further the path to the asset manifest file 314 which is retrieved from the first recording medium 60 by the asset manifest retrieving unit 710 and recorded on the second recording medium 80 by the asset recording unit 740 in the index manifest file 340 which is previously recorded on the second recording medium 80 and retrieved by the second index retrieving unit 720 (S1700). The index recording unit 750 updates the index manifest file 340 previously recorded on the second recording medium 80 by using the new index manifest file 340 generated by the index generating unit 745 (S1710).
