As described above, when a plurality of playlists 133 and 134 are created in a plurality of clients of the client A (301) and the client B (302) for the moving image content 113 stored in the server 200, these play lists are generated. Lists 133 and 134 are transmitted to server 200 and stored in accompanying information database 220. When editing the playlist 133 or 134 stored in the accompanying information database 220, each client acquires and edits the playlist 133 or 134 from the server 200 in each client, and the edited playlist is displayed in the accompanying information database. 220 can be stored.

  In this manner, a plurality of playlists 133 and 134 relating to one moving image content 113 can be stored in the accompanying information database 220, and the playlists 133 and 134 can be edited or used by each client.

  Next, the case where the moving image content stored in the content database 210 is played back by each client using the playlist stored in the accompanying information database 220 included in the server 200 will be described in detail with reference to the drawings.

  FIG. 7 is a diagram illustrating an example of the flow of moving image content or its playlist in the server 200, the client A (301), and the client B (302). That is, the case where the moving image content 113 is stored in the content database 210 included in the server 200 and the playlists 133 and 134 related to the moving image content 113 are stored in the accompanying information database 220 is shown. The playlists 133 and 134 are playlists created or edited by the client A (301) or the client B (302).

  In this case, when the client A (301) or the client B (302) reproduces the moving image content 113 stored in the content database 210, the client A (301) or the client B (302) plays from the server 200. The list 133 or 134 is acquired, and the moving image content 113 can be reproduced using the acquired playlist 133 or 134. For example, the client A (301) acquires the playlist 133, and based on the acquired playlist 133, the moving image content 116 to be reproduced is acquired from the moving image content 113, and the acquired moving image content 116 is reproduced. The In addition, the client B (302) acquires the play list 134, and based on the acquired play list 134, the moving image content 117 to be reproduced is acquired from the moving image content 113, and the acquired moving image content 117 is reproduced. The

  As described above, using the playlist stored in the server 200, among the moving image contents stored in the server 200, each client can acquire and reproduce only the portion of the moving image content necessary for reproduction. it can.

  Next, a case where a plurality of clients use a playlist stored in the accompanying information database 220 included in the server 200 for reproduction or editing will be described in detail with reference to the drawings.

  FIG. 8 is a diagram showing an example of the flow of moving image content or its playlist in the server 200, the client B (302), and the client C (303). That is, the case where the moving image content 118 is stored in the content database 210 provided in the server 200 and the playlists 137 to 139 related to the moving image content 118 are stored in the accompanying information database 220 is shown. The playlist 137 is a playlist created or edited by the client A (301), the playlist 138 is a playlist created or edited by the client B (302), and the playlist 139 is a client. It is assumed that the playlist is created or edited by C (303).

  In this case, when the client B (302) plays back the moving image content 118 stored in the content database 210, the playlist 137 created or edited by the client A (301) is acquired from the server 200 and acquired. Based on the play list 137, the moving image content 119 to be reproduced is acquired from the moving image content 118, and the acquired moving image content 119 is reproduced.

  When the client C (303) creates a playlist related to the moving image content 118 stored in the content database 210, the playlist 137 created or edited by the client A (301) and the client B (302) The playlist 138 created or edited by the above can be acquired from the server 200, and the playlist 139 related to the moving image content 118 can be created using the acquired playlists 137 and 138. Then, the created playlist 139 can be stored in the accompanying information database 220 included in the server 200. Further, based on the created playlist 139, the moving image content 120 to be reproduced can be acquired from the moving image content 118, and the acquired moving image content 120 can be reproduced.

  Thus, using each playlist created or edited by another client, playback of moving image content stored in the server 200, creation or editing of another playlist, and the like can be performed at each client.

  Next, a case where a plurality of moving image contents stored in the server 200 are reproduced using a playlist will be described in detail with reference to the drawings.

  FIG. 9 is a diagram schematically showing the moving image content stored in the content database 210 provided in the server 200 in time series. The moving image contents 411 to 426 shown in FIGS. 9A to 9C include, for example, Sagano who is the operator of the client A (301), Akino who is the operator of the client B (302), and the client C (303). This is a video taken with a digital video camera from time t1 to time t10 in a ski trip on January 10, 2007 by a plurality of persons including Suki who is an operator. Also, the moving image contents 411 to 426 shown in FIGS. 9A to 9C correspond to chapters, and the recorded recording sections are indicated by diagonal lines according to the shooting time. Further, a case will be described in which a playlist that is a list edited by selecting a desired chapter from one or a plurality of moving image contents is used as the accompanying information regarding the moving image content.

  In addition, representative images extracted in each recording section (chapter) are indicated by arrows from the corresponding recording section. For example, the representative images related to the moving image contents 411 to 415 are representative images 431 to 435, the representative images related to the moving image contents 416 to 420 are representative images 436 to 440, and the representative images related to the moving image contents 421 to 426 are representative images. 441 to 446. These representative images may be extracted based on the feature amount in each moving image content, or the head image in each moving image content may be selected.

  For example, the moving image contents 411 to 415 shown in FIG. 9A are taken by Sagano and are stored in the content database 310 of the client A (301) and also stored in the content database 210 of the server 200. It shall be. Also, the moving image contents 416 to 420 shown in FIG. 9B are taken by Akino and are stored in the content database 312 of the client B (302) and also stored in the content database 210 of the server 200. It shall be. The moving image contents 421 to 326 shown in FIG. 9C are taken by Suki and are stored in the content database 313 of the client C (303) and also stored in the content database 210 of the server 200. Shall.

  The representative images 431 to 446 are stored in the accompanying information database 220 of the server 200 as meta information related to the moving picture content, and are stored in the accompanying information database 220 of the client operated by the owner (photographer) of each moving picture content. It is assumed that

  FIG. 10 is a diagram showing an example of accompanying information regarding the moving image contents 411 to 426 shown in FIG. Such accompanying information is stored in each accompanying information database. Here, the accompanying information regarding the moving image contents 411 to 418 is illustrated, and description of the other accompanying information is omitted.

  As the accompanying information regarding the moving image contents 411 to 418, for example, as shown in FIG. 10, corresponding to the chapter ID 451, the start time 452, the recording time 453, the representative image 454, the recording position 455, the event 456, the user ID 457, and the group ID 458 Are stored in each accompanying information database. In FIG. 10, the accompanying information corresponding to the moving image contents 411 to 418 is denoted by the same reference numeral, and the chapter IDs 451 that are the respective identification numbers are described as “001” to “008”.

  The start time 452 is information indicating the date and time when the corresponding moving image content is shot. For example, when the corresponding moving image content is shot by the imaging device, the shooting date and time is recorded by the imaging device. For example, although the start time 452 is stored as “January 10, 2007, 11:00”, it is omitted and shown as “1/10...” In FIG.

  The recording time 453 is information indicating the length of time that the corresponding moving image content was shot. For example, when the length of the photographing time from the start time is 30 minutes, it is indicated as “00:30”, but the description is omitted in FIG.

  The representative image 454 is a reduced image extracted from the corresponding moving image content, and the corresponding representative images 431 to 438 are stored for the moving image contents 411 to 418. In FIG. 10, the representative image is not shown.

  The recording position 455 is information indicating the storage position of the corresponding moving image content in the content database 210 of the server 200, and is extracted based on this recording position when each client extracts the moving image content stored in the content database 210. It is. In FIG. 10, the recording positions 455 corresponding to the moving image contents 411 to 418 are shown as “1001” to “1008”, respectively.

  The event 456 is information indicating an event content or the like when the corresponding moving image content is shot. For example, “skiing trip” is stored for the moving image contents 411 to 426. Note that this event may be manually recorded by the user, or may be automatically recorded based on the shooting location and the shooting date and time. When an event is automatically recorded based on a shooting location and a shooting date and time, for example, images having the same shooting date and a shooting location within a predetermined range may be recorded as the same event. it can.

  The user ID 457 is information indicating an ID related to a user who owns the corresponding moving image content. For example, for the moving image contents 411 to 415, since Sagano is the owner, Sagano's user ID is stored. In FIG. 10, the user ID of Sagano is indicated as “Sagano 01”. Similarly, since Akino is the owner of the moving image contents 416 to 420, Akino's user ID is stored, and since Suki is the owner of the moving image contents 421 to 426, the user ID of Sugi is Stored.

  The group ID 458 is information indicating an ID related to a group to which a user who owns the corresponding video content belongs. This group is a group in the case where video content stored in a client connected to the server 200 is shared. The members belonging to the same group can play back, for example, the moving image content registered so as to be shared by other members via the server 200. In this example, a case where Sagano, Akino, and Suki belong to the group S will be described. In FIG. 10, the group ID related to the group S is shown as “group S01”.

  Next, browsing and reproducing the moving image content stored in the server 200 by each client will be described in detail with reference to the drawings.

  FIG. 11 is a diagram illustrating a display example displayed on the display unit 391 of the client A (301). 11, 17, 20, and the like will be described by taking client A (301) as an example, but the same applies to client B (302) and client C (303). The display unit 391 includes a “local image” display area 510, a “share / member” display area 520, a “representative image” display area 530, a “playlist” display area 540, and a “playlist” edit area 550. And are provided. The “playlist” editing area 550 will be described in detail with reference to FIG.

  12A is an enlarged view of the “share member” display area 520 shown in FIG. 11, and FIG. 12B is displayed in the “representative image” display area 530 shown in FIG. It is a figure which expands and shows a part of representative image.

  In addition, the client A (301) to the client C (303) belong to the same group “group S”, and the moving image content registered in the client A (301) to the client C (303) It is assumed that it is shared with. Further, as described with reference to FIG. 10, it is assumed that the moving image contents 411 to 426 illustrated in FIG. 9 are registered as “ski trip” as an event.

  The “local image” display area 510 is an area for displaying a folder to which each moving image content stored in the content database 310 of the client A (301) belongs. For example, in the content database 310, it is assumed that each moving image content shot at a wedding, an autumn sports day, or a ski trip is classified and stored for each folder by Sagano. In addition, each moving image content image | photographed on the ski trip is the moving image content 411 thru | or 315 shown to Fig.9 (a).

  Folders 511 to 513 displayed in the “local image” display area 510 correspond to folders to which moving image contents photographed at a wedding ceremony, an autumn sports day, and a ski trip belong, respectively. Also, on the right side of each folder, a folder name (event name) and a shooting date are displayed. For example, for the folder 551, “wedding” is displayed as the folder name, and “20066071” is displayed as the shooting date. In addition, among the folders displayed in the “local image” display area 510, folders displayed with hatching are folders in which each moving image content belongs is stored in the content database 210 of the server 200. For example, among the folders 511 to 513 displayed in the “local image” display area 510, moving image content belonging to the hatched folder 512 or 513 is stored in the content database 210 of the server 200, and these Indicates that video content is shared. Furthermore, when sharing other moving image contents, the moving image contents to be shared can be shared by storing them in the content database 210 of the server 200. For example, the “+ image registration” portion 514 is clicked with the cursor and a registration operation is performed, and each image belonging to the folder 511 is stored in the content database 210 of the server 200. Here, description regarding registration is omitted.

  The “share member” display area 520 is used when browsing video content shared in the group to which the client A (301) belongs among the video content stored in the content database 210 of the server 200. This is the area where icons are displayed. Here, it demonstrates in detail with reference to Fig.12 (a).

  In the upper part of the “share member” display area 520, the name of the group to which “share member” belongs is displayed. For example, since the group name to which Sagano, Akino, and Suki belong is “Group S”, “Share member“ Group S ”” is displayed.

  Further, as icons displayed in the “share member” display area 520, there are an icon indicating a registered event and an icon indicating an operator who owns the moving image content belonging to the event. For example, as an icon indicating an event, an icon 521 indicating an athletic meet in autumn and an icon 522 indicating a ski trip are displayed. For the icons indicating these events, it is preferable to use the most appropriate image for indicating the events. For example, a representative image related to the moving image content with the earliest shooting time can be used. In addition, the owner may select a representative image as an icon indicating an event, or may be selected by voting by another member.

  For example, an operator's face image can be used as the icon indicating the operator who owns the moving image content belonging to the event. For example, Sugano's face image is used as Sagano's icons 524 and 526, and Akino's face image is used as Akino's icons 525 and 527, and Suki's face image is used as Suki's icon 528. This face image may be stored as meta information related to each moving image content, or may be registered corresponding to the user ID.

  In addition, among the icons displayed in the “share member” display area 520, the icon and name selected by the operator are displayed differently from the others. In this example, a description is given using a square 523 indicated by diagonal lines.

  The “image” display area 530 is an area for displaying part or all of the moving image content stored in the content database 210 of the server 200. For example, in the “image” display area 530, a representative image related to the moving image content related to the icon selected in the “share member” display area 520 is displayed. For example, as shown in FIG. 11, representative images 431 to 446 corresponding to the moving image contents 411 to 426 shown in FIG. 9 are displayed in time series. When there are representative images that are not displayed with a large number of representative images, a desired representative image can be displayed using the scroll bar 531 provided on the right side of the “image” display area 530. . Here, although the case where each representative image is displayed in time series is shown, it is possible to display a list of moving picture content units for each photographer, scene units of feature sections, section units specified by the user, and the like. In addition, they may be arranged in order of photographing time for each photographer, viewing order, etc., or other orders may be used. Moreover, you may make it use the image regarding moving image content other than a representative image. In this way, when representative images related to a large number of video content such as video content shot by yourself or video content shot by others are displayed, you can choose which video to play back. May be difficult to do. Therefore, in the embodiment of the present invention, it is possible to efficiently reproduce using the playlist displayed in the “playlist” display area 540.

  Here, a display example of each representative image will be described in detail with reference to FIG. The representative images 441, 436, and 431 shown in FIG. 12B are enlarged views of the representative images 441, 436, and 431 displayed in the “image” display area 530 shown in FIG. As shown in FIG. 12B, in the lower part of the representative image displayed in the “image” display area 530, an icon indicating the owner of the moving image content corresponding to the representative image, each piece of information related to the moving image content, Is displayed. As each piece of information regarding the moving image content, for example, identification information regarding the moving image content and a recording time are displayed. For example, as shown in FIG. 12B, in the lower part of the representative image 441, an icon 561 indicating Sagano and “M4V0031.MP4 00:30:30” are displayed as identification information and recording time 562. Similarly, icons 563 and 565 and identification information and recording times 564 and 566 are also displayed for representative images 436 and 431. Here, the icon displayed in the lower part of the representative image is the same as the icon displayed in the “share member” display area 520. The correspondence between the icons 526 to 528 shown in FIG. 12A and the corresponding icons 561, 563, and 565 shown in FIG. 12B are indicated by arrows. In this way, by displaying the icon indicating the owner of the video content in the vicinity of the video content, it is possible to determine who the video content of the member displayed in the “share member” display area 520 is taken. It can be easily recognized. In the “image” display area 530 of FIG. 11 and the like, the lower part of the representative image, the identification information, and the recording time are not shown.

  In addition, when reproducing the moving image content corresponding to the representative image displayed in the “image” display area 530, it can be reproduced by double-clicking with the cursor placed on the representative image to be reproduced. . Also, the moving image being played can be stopped by another operation input.

  The “playlist” display area 540 is an area in which a playlist representative image that is a representative image related to a playlist that is a list in which the moving image content stored in the content database 210 of the server 200 is edited is displayed. That is, a representative image of the playlist is displayed. This playlist is a list edited by any one of the clients A (301) to C (303) or a list created by either the server 200 or the clients A (301) to C (303). Or a list created according to the history of the moving image content reproduced by any of the operators of the client A (301) to the client C (303) and stored in the accompanying information database 220 of the server 200. . The playlist will be described in detail with reference to FIG. 13 and FIG.

  FIG. 13 is a diagram schematically showing the relationship between the moving image contents 411 to 426 stored in the content database 210 provided in the server 200 and the playlist 610 created by editing the moving image contents 411 to 426. It is. Note that the moving image contents 411 to 426 shown in FIGS. 13C to 13E are the same as the moving image contents 411 to 426 shown in FIG. The playlist is, for example, a list related to the playback order of moving image content created by editing desired moving image content from the moving image contents 411 to 426. Note that the playlist 610 is created by, for example, Sagano.

  FIG. 13A is a diagram schematically showing a playlist 610 created by editing the moving image contents 411 to 426. Here, a case will be described as an example in which representative images related to each moving image content constituting a playlist created by editing the moving image contents 411 to 426 are arranged according to the playlist. FIG. 13B is a diagram virtually illustrating a case where moving image contents are arranged according to the edited playlist 610.

  As shown in FIGS. 13A and 13B, for each of a plurality of video contents stored in the content database 210 provided in the server 200, a video to be played by each client operator according to his / her preference. A list of contents can be created. When creating this playlist, it can be created using the video content of other members shared with the video content owned by itself. Also, the playlist order need not be arranged in time series, but can be arranged according to the preference of the operator.

  For example, as shown in FIGS. 13B to 13E, Sagano who is the creator of the playlist 610 uses the video content 416 to 426 owned by Akino or Suki together with the video content 411 to 415 owned by himself. A playlist 610 can be created. Note that the correspondence between the moving image contents arranged according to the playlist 610 shown in FIG. 13B and the moving image contents 411 to 426 shown in FIGS. 13C to 13E is indicated by arrows.

  FIG. 14 is a diagram schematically showing playlists 610, 620, and 630 created by editing the moving image contents 411 to 426 and playlist representative images that are representative images thereof. The play list 610 is the same as the play list 610 shown in FIG. Also, the playlist 620 is created by Akino, for example, and the playlist 630 is created by Suki, for example.

  In this example, a case will be described in which a representative image related to video content arranged at the head of each playlist is used as the playlist representative image. The playlist representative image may be selected according to the user's preference, or may be selected based on a score such as a feature amount.

  Thus, a playlist is created by the operator of each client, and playlist representative images related to the created playlist are displayed in frames 541 to 543 of the “playlist” display area 540. It should be noted that the playlist displayed in the frame 544 of the “playlist” display area 540 is not a playlist created by the operator of each client, but a “trusted play” created by the server 200 based on the feature amount and the like. List ".

  Further, when playing back each moving image content belonging to the playlist corresponding to the playlist representative image displayed in the “playlist” display area 540, double-click with the cursor placed on the playlist representative image to be played back. It can be played back by clicking. Also, the moving image being played can be stopped by another operation input. For example, by double-clicking the playlist representative 445 displayed in the frame 541 of the “playlist” display area 540, the moving image content is reproduced in the order shown in FIG.

  In addition, among playlists displayed in the “playlist” display area 540, playlists created by other members can also be played back. In this way, video content shot by multiple people can be edited and played according to preference, and the created playlist can be shared to create playlists created by other members' preferences. You can browse.

  FIG. 15A is an enlarged view (similar to the view shown in FIG. 12A) of the “share member” display area 520 shown in FIG. 11, and FIG. It is a figure which expands and shows a part of playlist representative image displayed on the "play list" display area 540 shown.

  Play list representative images 445, 438, 442, and 442 shown in FIG. 15B are play list representative images 445, 438, 442, displayed in frames 541 to 544 of the “play list” display area 540 shown in FIG. 442 is enlarged. As shown in FIG. 15 (b), in the lower part of the playlist representative image displayed in the “playlist” display area 540, an icon indicating the creator of the playlist corresponding to the playlist representative image, and the play The name of the list is displayed. As the name of the playlist, for example, “playlist 1”, “playlist 2”, “automatic playlist”, and the like are displayed. For example, as shown in FIG. 15B, in the lower part of the playlist representative image 445, an icon 571 indicating Sagano and “Playlist 1” 572 indicating the first playlist relating to Sagano are playlists. It is displayed as the name. Similarly, for the playlist representative images 438 and 442, icons 573 and 575 and playlist names 574 and 576 are displayed. Since the “automatic playlist” displayed in the frame 544 of the “playlist” display area 540 is created by the server 200, it is created instead of the icon indicating the creator of the playlist. An image related to the target event is used as an icon. For example, when the “automatic play list” is a play list created for the ski trip shown in FIG. 15A, the same icon as the icon 522 showing the ski trip shown in FIG. 15A is used. Can do.

  As described above, the icon displayed in the lower part of the playlist representative image is the same as the icon displayed in the “share member” display area 520. The correspondence between the icons 522, 526 to 528 shown in FIG. 15A and the corresponding icons 571, 573, 575, and 577 shown in FIG. 15B are indicated by arrows. In this way, by displaying an icon indicating the owner of the moving image content in the vicinity of the playlist representative image, a playlist created by any of the members displayed in the “share member” display area 520 is displayed. It can be easily recognized. In the “play list” display area 540 of FIG. 11 and the like, the icons in the lower part of the play list representative image and the name of the play list are omitted.

  16 and 17 are diagrams showing other display examples displayed on the display unit 391 of the client A (301). Here, client A (301) will be described as an example, but the same applies to client B (302) and client C (303).

  FIG. 16 is a diagram illustrating a display example when the icon 526 indicating Sagano is selected from the icons displayed in the “share member” display area 520. In this case, the icon 526 indicating the selected Sagano and the name are surrounded by a square 523 indicated by diagonal lines. In the “representative image” display area 530, only the representative image related to the selected icon is displayed. For example, only video content owned by Sagano is extracted from video content belonging to “ski trip” as an event, and this representative image is displayed. Specifically, as shown in FIG. 9A, representative images 431 to 435 corresponding to the moving image contents 411 to 415 owned by Sagano among the moving image contents 411 to 446 belonging to “ski travel” are displayed. .

  Also, in the “playlist” display area 540, only the playlist representative image and the entrusted playlist related to the selected icon are displayed. For example, out of playlists related to “skiing trip” as events, only playlists created by Hadano and entrusted playlists are extracted, and these playlist representative images are displayed. Specifically, among the playlist representative images shown in the “playlist” display area 540 of FIG. 11, only the playlist representative image 445 created by Sagano and the playlist representative image 442 of the entrusted playlist are displayed. .

  FIG. 17 is a diagram illustrating a display example when the icon 526 indicating Sagano is selected from the icons displayed in the “share member” display area 520. This display example shows a case where the display of the “representative image” display area 530 is different on the display screen shown in FIG. For this reason, the description other than the “representative image” display area 530 is omitted.

  FIGS. 11 and 16 show an example in which one representative image is displayed for one moving image content in the “representative image” display area 530, but the moving image content is represented using other images. Also good. FIG. 17 shows an example in which two or more images are extracted for one moving image content, and each image is displayed. For example, images 431 and 641 are extracted from the moving image content 411, images 432, 643, and 644 are extracted from the moving image content 412, images 433 and 645 are extracted from the moving image content 413, and images 434, 646, and 647 are extracted from the moving image content 414. Is extracted, and images 435 and 642 are extracted from the moving image content 415. FIG. Also, each of these images is shown surrounded by dashed frames 651 to 655 for each moving image content. In this example, an example in which the items are arranged in an order other than time series is shown. As described above, the representative image may be displayed in the “representative image” display area 530 in addition to arranging the representative images in time series.

  FIG. 18 is a diagram illustrating a display example when a cue search 501 for extracting feature points regarding each chapter is displayed in the upper part of the “play list” display area 540. The configuration other than the queue search 501 is the same as the configuration shown in FIG.

  FIG. 19A is an enlarged view of the queue search 501 shown in FIG. 18, and FIG. 19B is a part of the representative image displayed in the “representative image” display area 530 shown in FIG. It is a figure which expands and shows.

  For example, attribute information such as presence / absence of conversation, presence / absence of smile, presence / absence of face-up, small number of people or large number of people is created for each chapter based on the feature amount in each chapter, and a desired representative is created based on this attribute information. An image can be displayed. For example, when only the representative image corresponding to the scene with conversation is displayed in the “representative image” display area 530, the “conversation” check column 502 in the queue search 501 is checked as shown in FIG. Thereby, only the representative image corresponding to the chapter for which the conversation is “present” and the attribute information is created can be extracted, and only the extracted representative image can be displayed.

  In addition, an icon related to the created attribute information can be displayed over each representative image. For example, as shown in FIG. 19A, it is assumed that the “smile” check column 503 and the “large number” check column 505 in the queue search 501 are checked. In this case, for example, as shown in FIG. 19B, a large number mark indicating that the large number is extracted as the attribute information of the chapter corresponding to the representative image 441 in the upper left part of the representative image 441. In the upper left part of the representative images 436 and 431, smile marks 507 and 508 indicating that a smile is extracted as the attribute information of the chapter corresponding to the representative images 436 and 431 are attached. In this way, the display of the representative image can be changed using each attribute information, or a mark indicating the attribute information can be attached to the representative image. Since these can be used as indexes for selecting a representative image, editing of a playlist can be facilitated.

  FIG. 20 is a diagram illustrating a display example displayed on the display unit 391 of the client A (301), and is a diagram illustrating a display example when a playlist is edited using the “playlist” editing area 550. . The display screen shown in FIG. 20 is a display screen obtained by enlarging the “playlist” editing area 550 in the display screen shown in FIG. 11, and the other configurations are the same as those in FIG.

  FIG. 21 is a diagram showing an example of an editing method in the case of editing a playlist displayed in the “playlist” editing area 550 on the display screen shown in FIG.

  The “playlist” editing area 550 is an area for editing an operator's playlist or an entrusted playlist among the playlists displayed in the “playlist” display area 540. For example, when the display screen shown in FIG. 11 is displayed on the display unit 391, the “playlist” editing region 550 is shown in FIGS. 20 and 21 in accordance with an operation input from the operation receiving unit 392. Can be enlarged. In the “playlist” editing area 550, representative images corresponding to the playlist to be edited are displayed, a scroll bar 552, a pull-down button 553, a “save” button 555, and “delete”. A button 556 is displayed.

  The scroll bar 552 is a scroll bar for moving each representative image in the vertical direction when the number of representative images displayed in the “play list” editing area 550 is large. The pull-down button 553 is a button for displaying a playlist list 554 that is a list of playlists to be edited. The “save” button 555 is a button that is pressed when the playlist to be edited displayed in the “playlist” editing area 550 is updated and saved. The “delete” button 556 is a button to be pressed when deleting the playlist to be edited displayed in the “playlist” editing area 550.

  When editing a playlist in the “playlist” editing area 550, a pull-down button 553 is pressed to display a playlist list 554, and a playlist to be edited is selected from the playlist list 554. select. For example, it is assumed that “playlist 1” is selected. By selecting “Playlist 1”, among the playlists created by Sagano displayed in the “Playlist” display area 540, representative images constituting the playlist 1 displayed in the frame 541 are “Play”. It is displayed in the “list” editing area 550.

  If “new playlist” is selected, nothing is displayed in the “playlist” editing area 550 in order to create a new playlist.

  In this way, each playlist can be edited using the “playlist” editing area 550. For example, when changing the playback order of each moving picture content constituting the playlist, the playback order of each moving picture content is changed by moving the representative image displayed in the “playlist” editing area 550. Can do. For example, when the moving image content 413 corresponding to the representative image 433 is inserted between the moving image content 425 corresponding to the representative image 445 and the moving image content 426 corresponding to the representative image 446 to change the reproduction order, the cursor is moved. A drag operation is performed in a state of being superimposed on the representative image 433, and the representative image 433 is dropped between the representative image 445 and the representative image 446 as indicated by an arrow 581 in FIG.

  In addition, one or a plurality of moving image contents can be deleted from the moving image contents constituting the playlist. For example, when deleting the moving image content 426 corresponding to the representative image 446, for example, a drag operation is performed with the cursor placed on the representative image 446, and the representative image 446 is moved out of the “playlist” editing area 550. Move and drop. Thereby, the moving image content 426 corresponding to the representative image 446 can be deleted from the playlist 1.

  Further, one or a plurality of moving image contents can be added to each moving image content constituting the playlist. For example, when adding moving image content corresponding to the representative image displayed in the “representative image” display area 530 to the playlist, the representative image corresponding to the moving image content to be added is added to the “playlist” editing area. You can move up to 550 and add. For example, the moving image content 421 corresponding to the representative image 441 displayed in the “representative image” display area 530 is added between the moving image content 426 corresponding to the representative image 446 and the moving image content 416 corresponding to the representative image 436. In this case, a drag operation is performed with the cursor placed on the representative image 441 displayed in the “representative image” display area 530, so that the representative image 441 and the representative image 446 and the representative image 446 are displayed as indicated by an arrow 582 in FIG. A drop operation is performed between the representative images 436. Thereby, the moving image content 421 corresponding to the representative image 441 can be added to the playlist 1.

  Further, the playlist displayed in the “playlist” editing area 550 can be edited using the playlist displayed in the “playlist” display area 540. For example, the moving image content constituting one or more playlists displayed in the “playlist” display area 540 can be added to the playlist 1. For example, when adding video content constituting a playlist corresponding to the playlist representative image displayed in the “playlist” display area 540 to the playlist, the playlist representative corresponding to the playlist to be added Images can be added by moving to the “playlist” editing area 550. For example, when adding each moving image content constituting a playlist corresponding to the playlist representative image 442 displayed in the frame 543 of the “playlist” display area 540 between the representative image 436 and the representative image 440, A drag operation is performed in a state where the cursor is over the playlist representative image 442 displayed in the frame 543 of the “playlist” display area 540, and the playlist representative image 442 is displayed as a representative as indicated by an arrow 583 in FIG. A drop operation is performed between the image 436 and the representative image 440. The transition of the playlist when edited in this way will be described with reference to FIG.

  FIG. 22 is a diagram illustrating transition in the case where each moving image content constituting the playlist 630 is added to the playlist 610. FIG. 22A is a diagram schematically illustrating a case where each moving image content constituting the playlist 630 is added between the moving image contents 416 and 420 (representative images 436 and 440) constituting the playlist 610. FIG. . For example, the playlist 630 is added at the position of the arrow 660.

  FIG. 22B is a diagram showing a case in which representative images corresponding to the moving image contents constituting the playlist after the additional processing shown in FIG. As shown in FIG. 22B, the moving image contents constituting the playlist 630 are added to the moving image contents 416 and 420 (representative images 436 and 440) constituting the playlist 610.

  When the playlist to be edited displayed in the “playlist” editing area 550 is updated and saved, the “save” button 555 can be pressed to update. In this case, the playlist to be edited stored in the accompanying information database 320 is updated, and this update information is transmitted to the server 200. In addition, when the playlist to be edited displayed in the “playlist” editing area 550 is deleted, a “delete” button 556 is pressed. In this case, the playlist to be edited stored in the accompanying information database 320 is deleted, and this deletion information is transmitted to the server 200.

  In this way, the playlist of the operator can be easily edited using the playlist created by other members.

  If the selection of the icon displayed in the “Share / Member” display area 520 is changed, the “playlist” edit is performed on the representative image constituting the “reliable playlist” regarding the selected icon after the change. You may make it display on the area | region 550. FIG. As a result, it is possible to quickly edit the own playlist relating to the selected icon after the change using the “reliable playlist” displayed in the “playlist” editing area 550. In addition, when the same icon in the “Share / Member” display area 520 is selected, when the moving image content corresponding to any one of the representative images is sequentially reproduced by the operation input by the user, the reproduced moving image The representative images corresponding to the contents may be displayed side by side in the “play list” editing area 550, and this reproduction history may be created as its own playlist.

  Next, the operation of the image processing system 100 in the embodiment of the present invention will be described with reference to the drawings. Here, the operations of the server 200 and the client A (301) will be described, but the client B (302) or the client C (303) is the same as the client A (301).

  FIG. 23 is a flowchart illustrating a processing procedure of login processing by the client A (301) configuring the image processing system 100. In this example, when logging into the server 200, an example will be described in which a group ID and password are input from the operation receiving unit 392 of the client A (301) and belong to a group that matches the group ID and password.

  First, it is determined whether or not an operation input to the server 200 is received from the operation receiving unit 392 (step S901). When an operation input to the server 200 is not accepted (step S901), the process proceeds to step S907. On the other hand, when an operation input to the server 200 is accepted (step S901), it is determined whether the operation input is an operation input related to a new login to the server 200 (step S902).

  If the operation input is not an operation input related to a new login (step S902), request information for the server 200 corresponding to the operation input is transmitted (step S903). On the other hand, when the operation input is an operation input related to a new login (step S902), it is determined whether or not the operation input is an operation input related to a new group creation (step S904). For example, when none of the clients A (301) to C (303) is logged in to the server 200 and the client A (301) logs in as the owner of the “group S”, an operation related to the creation of a new group Input is accepted.

  If the operation input is an operation input related to the creation of a new group (step S904), the fact that a new group is to be created and the user ID of the client A (301) are transmitted to the server 200 via the network 101 (step S904). S905). On the other hand, if the operation input is not an operation input related to creation of a new group (step S904), a group ID corresponding to the operation input (for example, a group ID related to “group S”), its password, and client A (301). ) Is transmitted to the server 200 via the network 101 (step S906).

  Subsequently, it is determined whether an unapproved notification is received from the server 200 (step S907). When an unapproved notification is not received from the server 200 (step S907), the process proceeds to step S909. When an unapproved notification is received from the server 200 (step S907), the received unapproved notification is displayed on the display unit 391. Is displayed (step S908).

  Subsequently, it is determined whether or not an operation input for the unapproved notification received from the server 200 has been accepted (step S909). When the operation input for the unapproved notification is not accepted (step S909), the process proceeds to step S911. When the operation input for the unapproved notification is accepted (step S909), the operation input for the unapproved notification is performed. The corresponding response information is transmitted to the server 200 via the network 101 (step S910).

  Subsequently, it is determined whether group information is received from the server 200 via the network 101 (step S911). The group information is information for sharing information within the group. For example, a group list, members belonging to the group, playlists belonging to the group, video content lists belonging to the group, representatives belonging to the group Contains images. If no group information is received from the server 200 (step S911), the login process is terminated. On the other hand, when the group information is received from the server 200 (step S911), the display content displayed on the display unit 391 is changed based on the received group information (step S912).

  FIG. 24 is a flowchart illustrating a processing procedure of login processing by the server 200 configuring the image processing system 100.

  First, it is determined whether or not an operation input has been received from a client connected via the network 101 (step S921). If no operation input is received from any client (step S921), the login process is terminated. On the other hand, when an operation input is accepted from any client (step S921), it is determined whether or not the received operation input is an operation input related to a new login to the server 200 (step S922).

  If the received operation input is not an operation input related to a new login (step S922), processing for request information corresponding to the operation input is executed (step S923). On the other hand, when the received operation input is an operation input related to new login (step S922), it is determined whether or not the operation input is an operation input related to new group creation (step S924).

  When the operation input is an operation input related to the creation of a new group (step S924), the user corresponding to the received user ID is newly registered as the owner of the new group, and the group ID and the group are associated with the new group. A password is registered (step S925). On the other hand, if the operation input is not an operation input related to new group creation (step S924), does the group ID and password corresponding to the operation input match the group ID and password stored in the accompanying information database 220? It is determined whether or not (step S926).

  If the group ID and password corresponding to the operation input match the group ID and password stored in the accompanying information database 220 (step S926), the user ID received together with the group ID and password is approved. The user ID is registered in the group corresponding to the group ID (step S927). Subsequently, group information related to the group is transmitted to the client corresponding to each user ID belonging to the group in which the user ID is registered in step S927 (step S928).

  On the other hand, if the group ID and password corresponding to the operation input do not match any group ID and password stored in the accompanying information database 220 (step S926), the user received together with the group ID and password Since the ID is unapproved, an unapproved notification indicating unapproved is transmitted to the client corresponding to the user ID (step S929).

  FIG. 25 is a flowchart showing a processing procedure of moving image content registration processing by the client A (301) constituting the image processing system 100. In this example, storing and sharing the moving image content stored in each client in the content database 210 of the server 200 is referred to as registering the moving image content in the server 200.

  First, it is determined whether or not an operation input for registering the moving image content stored in the content database 210 in the server 200 is received from the operation receiving unit 392 (step S931). When the operation input for registering the moving image content in the server 200 is not accepted (step S931), the process proceeds to step S935. On the other hand, when an operation input for registering the moving image content in the server 200 is received (step S931), it is determined whether or not the event for which the moving image content is to be registered is a new event (step S932). .

  If the event for which the moving image content is to be registered is a new event (step S932), the fact that the new event is to be created, the moving image content, and the playlist related to the moving image content are sent to the server 200 via the network 101. It is transmitted (step S933). On the other hand, if the event for which the moving image content is to be registered is not a new event (step S932), the event to be registered, the moving image content, and the playlist related to the moving image content are transmitted to the server 200 via the network 101. (Step S934).

  Subsequently, it is determined whether or not the updated group information is received from the server 200 (step S935). If the updated group information is not received from the server 200 (step S935), the operation of the moving image content registration process is terminated. On the other hand, when the updated group information is received from the server 200 (step S935), the display content displayed on the display unit 391 is changed based on the received group information (step S936).

  FIG. 26 is a flowchart showing the processing procedure of the moving image content registration processing by the server 200 constituting the image processing system 100.

  First, it is determined whether or not an operation input for registering moving image content has been received from a client connected via the network 101 (step S931). If no operation input for registering moving image content has been received from any client (step S941), the operation of the moving image content registration process is terminated. On the other hand, when an operation input for registering the moving image content in the server 200 is received (step S941), it is determined whether or not the event for registering the moving image content is a new event (step S942). .

  If the event for which the moving image content is to be registered is a new event (step S942), a folder related to the new event is created, and the received moving image content is registered in the folder related to the new event (step S943). On the other hand, when the event for which the moving image content is to be registered is not a new event (step S942), the moving image content is registered in the folder related to the event to be registered (step S944).

  Subsequently, feature amounts are extracted from the registered moving image content (step S945). Subsequently, an entrusted playlist related to the registered moving image content is created based on the extracted feature amount (step S946). This entrusted playlist can be created for each event, for example.

  Subsequently, updated contents (a list and a representative image regarding the registered moving image content, an updated entrusted play list, etc.) are transmitted to each client of the group to which the client that transmitted the registered moving image content belongs ( Step S947).

  FIG. 27 is a flowchart illustrating a processing procedure of playlist editing processing by the client A (301) configuring the image processing system 100.

  First, it is determined whether or not an operation input for editing a desired playlist among the playlists stored in the accompanying information database 320 has been received from the operation receiving unit 392 (step S951). For example, it is determined whether or not a pull-down button 553 displayed in the “playlist” editing area 550 is pressed and a desired playlist is clicked. If the operation input for editing the playlist is not accepted (step S951), the process proceeds to step S953. If the operation input for editing the playlist is accepted (step S951), the operation input is performed. A representative image related to each moving image content constituting the playlist selected in accordance with is displayed in the “playlist” editing area 550 (step S952).

  Subsequently, it is determined whether or not an operation input for creating a new playlist has been received from the operation receiving unit 392 (step S953). For example, it is determined whether or not a pull-down button 553 displayed in the “playlist” editing area 550 is pressed and a new playlist is clicked. If an operation input for creating a new playlist has not been accepted (step S953), the process proceeds to step S955. If an operation input for creating a new playlist has been entered (step S953), a new playlist is created. A screen for creating a playlist is displayed (step S954). For example, the “playlist” editing area 550 is in a state where no representative image is displayed.

  Subsequently, it is determined whether or not an operation input indicating that a representative image displayed in the “image” display area 530 is added to the playlist to be edited (or a new playlist) has been received (step S955). ). If the operation input for adding the representative image displayed in the “image” display area 530 is not accepted in the playlist to be edited (step S955), the process proceeds to step S957 and the playlist to be edited is entered. If an operation input for adding the representative image displayed in the “image” display area 530 is received (step S955), the representative image for which the operation input has been added is added to the playlist to be edited. Is displayed (step S956). For example, when a representative image that has been added is moved by a drag-and-drop operation, the representative image is inserted and displayed at the dropped position.

  Subsequently, it is determined whether or not an operation input for adding another playlist displayed in the “playlist” display area 540 is accepted to the playlist to be edited (or a new playlist). (Step S957). When an operation input for adding another playlist displayed in the “playlist” display area 540 is not accepted in the playlist to be edited (step S957), the process proceeds to step S959, where the editing target is edited. When an operation input indicating that another playlist displayed in the “playlist” display area 540 is added to the playlist is received (step S957), the other playlist for which the operation input has been made is received. Each representative image included in is added to the playlist to be edited and displayed (step S958). In this case, when the playlist representative image that has been added is moved by a drag-and-drop operation, the representative image that constitutes the playlist is inserted and displayed at the dropped position.

  Subsequently, it is determined whether or not an operation input for moving the representative image displayed in the “playlist” editing area 550 has been made (step S959). If the operation input for moving the representative image displayed in the “playlist” editing area 550 is not made (step S959), the process proceeds to step S953, and the representative image displayed in the “playlist” editing area 550 is displayed. Is input (step S959), it is determined whether the destination of the representative image is within the “playlist” editing area 550 (step S960). If the movement destination of the representative image is within the “playlist” editing area 550 (step S960), the representative image is moved to the position of the movement destination, and the order of the representative images is changed according to the movement. (Step S961). On the other hand, if the destination of the representative image is not within the “playlist” editing area 550 (step S960), the moved representative image is deleted from the “playlist” editing area 550 (step S962).

  Subsequently, it is determined whether or not the “save” button 555 displayed at the top of the “playlist” editing area 550 has been pressed (step S963). If the “Save” button 555 is not pressed (Step S963), the process proceeds to Step S965. If the “Save” button 555 is pressed (Step S963), the “Playlist” editing area 550 is displayed. The playlist is updated based on the order of the representative images that are updated (in the case of a new playlist, a new playlist is created) and stored in the accompanying information database 320, and the updated playlist is transmitted to the server 200. (Step S964).

  Subsequently, it is determined whether or not the “delete” button 556 displayed at the top of the “play list” editing area 550 has been pressed (step S965). When the “delete” button 556 has not been pressed (step S965), the operation of the playlist editing process is terminated. When the “delete” button 556 has been pressed (step S965), “playlist” The playlist to be edited displayed in the editing area 550 is deleted, the corresponding playlist in the incidental information database 320 is deleted, and the fact that the playlist has been deleted is transmitted to the server 200 (step). S966).

  FIG. 28 is a flowchart showing a processing procedure for reproducing moving image content or displaying a representative image thereof by the client A (301) constituting the image processing system 100.

  First, it is determined whether or not an operation input for selecting one of the events displayed in the “share member” display area 520 has been made (step S971). If an operation input for selecting an event has not been made (step S971), the process proceeds to step S973. If an operation input for selecting an event has been made (step S971), it belongs to the selected event. A representative image related to each moving image content is displayed in the “image” display area 530, and each play list related to the selected event is displayed in the “play list” display area 540 (step S972).

  Subsequently, it is determined whether or not an operation input for selecting one of the members displayed in the “share member” display area 520 has been made (step S973). If an operation input for selecting a member has not been made (step S973), the process proceeds to step S975. If an operation input for selecting a member has been made (step S973), it belongs to the selected member. A representative image related to each moving image content is displayed in the “image” display area 530, and each play list related to the selected member is displayed in the “play list” display area 540 (step S974).

  Subsequently, whether or not an operation input for reproducing a moving image corresponding to any one of the representative images displayed in the “image” display area 530 or the “playlist” editing area 550 is made. Determination is made (step S975). For example, the representative image corresponding to the moving image content to be reproduced is double-clicked. If the operation input for reproducing the representative image has not been performed (step S975), the process proceeds to step S977. If the operation input for reproducing the representative image has been performed (step S975), the operated representative is displayed. A transmission request for transmitting the moving image content corresponding to the image is transmitted to the server 200 (step S976). Subsequently, the moving image content corresponding to the transmission request is received from the server 200, and the moving image content is reproduced (step S977). When the moving image content corresponding to the operated representative image is stored in the content database 310 of the own device, the moving image content stored in the content database 310 of the own device is reproduced. For example, based on the user ID corresponding to the moving image content, it is determined whether the moving image content corresponding to the operated representative image is stored in the content database 310 of the own device.

  Subsequently, it is determined whether or not an operation input for reproducing the moving image content corresponding to any one of the playlists displayed in the “playlist” display area 540 is made (step S978). ). For example, a representative image corresponding to a playlist to be reproduced is double-clicked. If an operation input for reproducing the playlist has not been made (step S978), the operation of the reproduction or display process is terminated. On the other hand, when an operation input for reproducing the playlist is made (step S978), a transmission request for transmitting the moving image content corresponding to the operated playlist is transmitted to the server 200 (step S979). . Subsequently, the moving image content corresponding to the transmission request is received from the server 200, and the moving image content is reproduced (step S980).

  Next, a modification of the embodiment of the present invention will be described in detail with reference to the drawings.
