  Examples of the present invention will be described below.

  Below, the 1st Example of this invention is described based on FIGS.

  FIG. 1 is a block diagram showing an electrical configuration of the photographic recording / displaying apparatus 100.

  In the photographing record display device 100 of FIG. 1, photographing means for photographing a video is realized by the control unit 110 controlling the imaging unit 107 to acquire the video as digital data. The image processing means is realized by the control unit 110 controlling the digital data acquired by the imaging unit 107 to be transferred to the image processing unit 103 and processed and compressed by the image processing unit 103.

  Similarly, the recording means for recording the captured video is such that the control unit 110 controls each processing unit to transfer and record the data processed and compressed by the image processing unit 103 to the removable recording unit 104. Realized. Similarly, the information acquisition and generation means for adding additional information is realized by the control unit 109 controlling the reduced image generating unit 106 to generate a reduced image (thumbnail). The reduced image generation unit 106 generates a reduced image (thumbnail) by referring to information obtained from an external device via the communication unit 101, information recorded in the memory 108, and information recorded in the removable recording unit 104. To do. For example, when the external device is a GPS (Global Positioning System), position information is obtained as information, so the reduced image generation unit 106 generates a reduced image (thumbnail) from the position information. Further, when the photographing record display device 100 has an information acquisition unit, a reduced image may be generated using the information. When a reduced image (thumbnail) template is recorded in the detachable recording unit 104, the reduced image generation unit 106 generates a reduced image (thumbnail) in combination with the position information.

  FIG. 2 shows a state in which the photographing record display device 100 is connected to an external position information acquisition device 200. Reference numeral 210 denotes a serial or parallel cable for connecting the photographing record display device 100 and the external position information acquisition device 200. The position information acquisition device 200 is a GPS device and can acquire position information.

  Hereinafter, an operation of generating a map thumbnail from the obtained position information and adding it to video data will be described.

  When start of shooting is requested by the operation unit 110 of the shooting / recording display device 100, the control unit 109 starts acquisition of video by the imaging unit 107. The captured digital data is subjected to image processing by the image processing unit 103 and recording on the removable recording unit 104 is started. At the same time, the control unit 109 requests acquisition of position information from the position information acquisition apparatus 200 connected by the cable 210 via the communication unit 101. Communication is established by controlling the communication protocol understood by both the imaging record display device 100 and the position information acquisition device 200 by the communication auxiliary unit 102. Details of the communication protocol are omitted for simplicity.

  The position information acquired from the position information acquisition device 200 via the communication unit 101 and the communication auxiliary unit 102 is stored in the memory 108 by the control unit 109. FIG. 3 shows the configuration of the position information stored in the memory 108, in which an identifier 301, latitude 302, longitude 303, and position information acquisition time 304 indicating video data being shot and recorded are recorded. Further, map data is compressed and stored in the memory 108 as an image. FIG. 4 is an example of the map image 400 recorded in the memory 108, and the position can be specified from the latitude 402 and the longitude 401 according to the size of the map image 400. In the case of the present embodiment, if the size of the map image 400 is large, the position that can be specified by the longitude 402 and the latitude 401 becomes detailed. When the position information (see FIG. 3) is acquired and recorded and the photographing is completed, the control unit 109 specifies the position on the map from the latitude and longitude information acquired by referring to the map image 400 in the memory 108. In FIG. 4, reference numeral 403 denotes a position specified by the acquired longitude and latitude information. The control unit 109 cuts out the data at the positions of the map images 400 to 403 by the image processing unit 103 and generates a reduced image (map thumbnail). Here, in this embodiment, the size of the map image 400 stored in the memory 108 is 2000 PIXEL (701) vertically and 2000 PIXEL (702) horizontally as shown in FIG. The image display ranges are latitudes 47 degrees (703) to 29 degrees (704), longitudes 129 degrees (705) to longitudes 147 degrees (706).

  That is, 1 degree latitude is indicated by about 111 PIXEL and 1 degree longitude is indicated by about 111 PIXEL. These values are approximate values for explanation.

  The value obtained from the position information indicates (403), and the values are latitude 43 degrees (707) and longitude 142 degrees (708).

  From the above data, if the upper left position in the map image 400 is (X, Y) = (0, 0), the position indicated by (403) is (X, Y) = (1443, 1554). With this point as the center, the control unit 109 trims an image having a preset size from the map image 400 by the image processing unit 103 to generate a reduced image (thumbnail). Here, the size of the thumbnail to be generated may be set by the user.

  The control unit 109 additionally records the generated thumbnail as a map thumbnail of the video data recorded in the removable recording unit 104 indicated by the identifier 301. Here, the video data is recorded as metadata as a header data portion 501, a footer data portion 503, and compressed video data 502 as shown in FIG. 5.

  A basic thumbnail extracted from a normal video body is recorded in the header data portion 501. The map thumbnail is recorded as metadata in the footer data portion 503. In the footer data portion 503, a thumbnail list identifier 601 indicating that a thumbnail other than the basic thumbnail is added is recorded, and subsequently, the number of thumbnails added as 602 is recorded. Subsequently, a byte offset from the position where the thumbnail list identifier 601 indicating the position where the next thumbnail identifier 604 is recorded is recorded as 603. A byte offset 605 from a position where a thumbnail identifier 604 for identifying a thumbnail and a thumbnail list identifier 601 indicating the position where the actual thumbnail data 613 is recorded is recorded at the position indicated by the byte offset 603. Has been. Next, a byte offset 606 from the position where the thumbnail list identifier 601 indicating the position where the next thumbnail identifier is recorded is recorded. Thereafter, identifiers 607 and 610 indicating thumbnails, offsets 608 and 611 to actual data, and offsets 609 and 612 to the next thumbnail identifier are specified by the identifier 301 by the number of thumbnails indicated by 602. It is recorded as a thumbnail of data. Only in the case of the last thumbnail identifier, the offset to the next thumbnail identifier is zero.

  The control unit 109 first searches for the thumbnail list identifier 601 from the footer data unit 503 in order to add the generated map thumbnail, which is a reduced image of 403, to the video data specified by the identifier 301. If the thumbnail list identifier 601 has already been recorded, the number 602 indicating the number of thumbnails is updated, the thumbnail identifier indicating the map thumbnail to be newly added is added to the end of the thumbnail list, and the free space in the footer data portion 503 is obtained. The map thumbnail data is recorded in the area, and an offset to the data is recorded.

  On the other hand, when the thumbnail list identifier 601 is not recorded, the thumbnail data is added after the thumbnail list identifier 601 is added to the empty area of the footer data portion 503. Here, the map image 400 is recorded in the memory 108, but may be recorded in the removable recording unit 104.

  The map thumbnail can be added to the video data by the procedure described above. Further, the map image 400 may be acquired from an external device via the communication unit 101 instead of the memory 108 to generate a map thumbnail.

  Next, a method for adding not the map thumbnail but image data indicating the location (for example, an image of a tourist spot) to the recording data as thumbnail data from the position information will be described.

  As shown in FIG. 8, a place thumbnail image data group indicating the characteristics of each region is recorded in the removable recording unit 104 included in the photographing record display device 100. The list 800 in FIG. 8 is recorded as data in the detachable recording unit 104. The list 800 includes the file name 801 of each location thumbnail image in the thumbnail image data group, the latitude 803 and the longitude 802 of the point indicated by the image. In addition, data 804 describing what range the image data indicates is recorded.

  Similar to the means for generating map thumbnail images, the control unit 109 acquires position information from an external GPS or the like via the communication unit 101. The control unit 109 selects and determines a thumbnail image to be added to the recording data from the acquired position information and the thumbnail group list 800, and adds it to the recording data in the same manner as the map thumbnail.

  In the above description, the means for adding a map image or an image that can specify a location as a thumbnail to the video data has been described. However, for example, an image indicating the weather may be added as a thumbnail. In that case, the weather information is acquired from an external device, for example, a mobile phone, and recorded in the memory 108 or the detachable recording unit 104 in advance according to the weather as in the case of generating the map thumbnail described above. A thumbnail image indicating the weather that is present is added to the video data.

  Similarly, it is possible to acquire time information from the outside and add a thumbnail representing the season in the same manner from the information. In that case, time information provided in the photographing record display device 100 may be used.

  Here, the thumbnail identifiers 604, 607, and 610 in FIG. 6 are thumbnail identifiers indicating the respective categories when the above-described map thumbnail, weather thumbnail, season thumbnail, and location thumbnail are added to the video data body, for example. As recorded. For example, an identifier of 0x00000001 is recorded for the thumbnail of the map thumbnail category, an identifier of 0x00000002 for the thumbnail of the seasonal thumbnail category, an identifier of 0x00000004 for the thumbnail of the weather thumbnail category, and an identifier of 0x00000008 for the location thumbnail category.

  In FIG. 9, video data 901, 902, 903 and 904 are respectively stored in the removable recording medium 104 of the photographic recording / display apparatus 100 as “Mov_0001.MPG”, “Mov_0002.MPG”, “Mov_0003.MPG”, “Mov_0004”. .MPG ”is recorded as data identified.

  "Mov_0001.MPG" (901) is 905, "Mov_0002.MPG" (902) is 906, "Mov_0003.MPG" (903) is 907, and "Mov_0004.MPG" (904) is 908. The thumbnails are recorded in the header data portion 501 shown in FIG. Reference numerals 909 to 912 are recorded in the footer data portion 503 of each video data as the above-described map thumbnails.

  In FIG. 6, a thumbnail recording method for the thumbnail data in the footer data portion 503 is shown. At this time, the thumbnail identifier 604 records 0x00000001 indicating the category of the map thumbnail. Similarly, 913 to 916 are recorded as seasonal thumbnails, 917 to 920 are recorded as weather thumbnails, and 921 to 924 are recorded as location thumbnails in the footer data portion 503 of each video data as identifiers 0x00000002, 0x00000004, and 0x00000008, respectively.

  FIG. 10 is an example of an interface display screen in the case where the user selects to reproduce recorded video data. The GUI 1001 shown in FIG. 10 is displayed on the display unit 105 shown in FIG. The GUI 1001 displays a thumbnail 1002 of recorded video data. In this case, the basic thumbnail recorded in the header data portion 501 of FIG. 5 is displayed. The user can start reproduction of desired video data by the operation unit 110 by selecting and determining a thumbnail by operating the selector 1003) with the operation unit 110 of FIG.

  On the other hand, thumbnails added separately from the basic thumbnails are selected / determined by operating the selector 1102 with the operation unit 110 to select the thumbnail category 1102 to be displayed from the thumbnail category 1103 using the GUI 1101 for the thumbnail category shown in FIG. Is displayed. When the thumbnail category is selected on the GUI 1101, the control unit 109 searches the footer data unit 503 according to the format of FIG. 6 as to whether or not the identifier indicating the thumbnail category selected from each recorded video data is recorded. To do. For example, when the map thumbnail category is selected in the GUI 1101, it is searched whether or not the value of 0x00000001 is recorded as an identifier, and the thumbnail indicated by the identifier is displayed. FIG. 12 shows the result of displaying the map thumbnail category on the GUI 1001, and the user can select video data from the map thumbnail.
