Description

  The present invention relates to a technique for setting a title in an image.

  In recent years, a digital still camera (hereinafter also referred to as “DSC”) is widely used as an image generation apparatus that generates an image file representing an image of a subject by photographing the subject using an imaging element.

  The image file at the time of generation by an image generation device such as DSC does not have information that can specify the content of the image. For example, the file name of the image file is not capable of specifying the content of the image. For this reason, in general, in order to manage an image file, a user sets a title that can specify the content of the image for the image file. For example, the user sets the image title by transferring the image file from the image generation apparatus to a personal computer (hereinafter also referred to as “PC”) and changing the file name of the image file to a name representing the title of the image.

  On the other hand, in recent years, an image display device other than a PC capable of displaying an image generated by an image generation device has been developed (for example, Patent Document 1). Patent Document 1 discloses a digital television (hereinafter also referred to as “DTV”) that functions as an image display device. This DTV includes a card slot and an image display application program, and can display an image on a screen based on an image file stored in a memory card inserted in the card slot. By using such a DTV, the user can browse images more easily.

A-2. Image management processing:
2 and 3 are flowcharts showing the flow of image management processing in the network system 10 of this embodiment. The image management processing of the present embodiment performs image display (image browsing) based on the image file IF in the memory card MC inserted in the card slot 132 and sets the image title in the digital television 100 (FIG. 1). This is a process for registering the image and the title in the DLNA server 300 in association with each other.

  Before the image management process is started, in the network system 10 (FIG. 1), the DTV 100 and the DLNA server 300 participate in the LAN according to the DLNA specification and recognize each other's existence and address. To do.

  In step S110 (FIG. 2), the image display processing unit 212 (FIG. 1) of the DTV 100 acquires the image file IF stored in the memory card MC and displays an image on the display unit 120 based on the image file IF. . FIG. 4 is an explanatory diagram illustrating an example of an image display screen displayed on the display unit 120. In this embodiment, as shown in FIG. 4, a plurality of images stored in the memory card MC are displayed in a list on the image display screen. When the memory card MC stores more image files IF than can be displayed on one image display screen, a desired image can be displayed by switching pages. Thumbnail image data included in the image file IF is used for image display. Note that the image display on the display unit 120 may be performed so that only one image is displayed on the image display screen. Further, the image may be displayed based on the image data itself, not the thumbnail image.

  In step S120 (FIG. 2), the image management processing unit 210 (FIG. 1) of the DTV 100 inputs a title setting start instruction by the user via the instruction input unit 150. The instruction to start title setting by the user is performed when the user operates the remote controller RC to select an image for title setting on the image display screen (FIG. 4) and select a “title setting” button.

  In step S130 (FIG. 2), the attribute information reading unit 214 (FIG. 1) of the DTV 100 captures an image capture date from the attribute information of the image file IF corresponding to the image selected in step S120. Get information.

  In step S140 (FIG. 2), the title setting unit 216 (FIG. 1) of the DTV 100 displays a title setting screen (UI) on the display unit 120. FIG. 5 is an explanatory diagram illustrating an example of a title setting screen. As shown in FIG. 5, the image selected in step S120 is displayed on the title setting screen. Further, the title setting screen includes a title candidate space TS for displaying title candidates and a keyword space KS for displaying keywords used for title setting.

  The keyword space KS included in the title setting screen (FIG. 5) has a three-column configuration. The three columns of the keyword space KS correspond to “when”, “who”, and “how”. The column corresponding to “when” is a space for displaying a keyword related to time. The column corresponding to “who” is a space for displaying a keyword related to the subject. The column corresponding to “What's wrong” is a space for displaying a keyword related to an action or a state. Note that in the stage of step S140, it is assumed that no keyword is displayed in the keyword space KS.

  In step S150 (FIG. 2), the title setting unit 216 (FIG. 1) of the DTV 100 performs keyword display processing. The keyword display process is a process for displaying a keyword in the keyword space KS included in the title setting screen (FIG. 5). The title setting unit 216 performs keyword display processing using various data.

  First, the title setting unit 216 displays the shooting date of the image in the “when” column of the keyword space KS based on the shooting date information acquired from the image file IF in step S130. Further, the title setting unit 216 may acquire information representing today's date from a timer (not shown) of the DTV 100 and display the current date in the “when” column of the keyword space KS. Further, the title setting unit 216 may display only the shooting date or today's year. FIG. 5 shows how the date and year are displayed in the “when” column of the keyword space KS in this way.

  Second, the title setting unit 216 displays keywords based on a word file (not shown) stored in the internal memory 160 of the DTV 100. In this embodiment, a word file including a keyword that identifies a user, his / her family, and the like is stored in the internal memory 160 of the DTV 100. This word file is stored in the DTV 100 when the DTV 100 is produced by BTO (Built To Order). By using this word file, the title setting unit 216 can display keywords that specify the user, their family, and the like in the “who” column of the keyword space KS. FIG. 5 shows an example in which names of users and the like are displayed in the “Who” column of the keyword space KS in this way.

  In addition, the word file stored in the production of the DTV 100 includes keywords representing typical actions and states that can be used for image titles. The title setting unit 216 displays such keywords in the “how” column of the keyword space KS. FIG. 5 shows an example in which words such as “travel” and “camp” are displayed as keywords representing typical actions and states in the “how” column of the keyword space KS.

  Various other data can be used for the keyword display processing by the title setting unit 216. For example, the word file WF stored in the memory card MC or the word file WF stored in the external storage device 330 of the DLNA server 300 may be used for the keyword display processing by the title setting unit 216.

  As keywords displayed in each column of the keyword space KS, various keywords other than the example shown in FIG. 5 can be adopted. For example, “yesterday” or “last week” may be used as a keyword to be displayed in the “when” column of the keyword space KS. Note that a date designated by the user may be displayed by a date input UI provided separately. Further, as a keyword to be displayed in the “who” column of the keyword space KS, a word other than a word representing a person such as “camp”, “mountain”, “river”, “hot spring” may be used.

  When a plurality of word files WF are used for the keyword display process, the word file WF obtained by merging the contents of all the word files WF is stored in a predetermined storage area (for example, the memory card MC), and the word The keyword display process may be performed based on the file WF.

  The keywords displayed in each column of the keyword space KS may be associated with each other, and the keyword display process may be performed according to the association. For example, when the name of a specific person displayed in the “who” column of the keyword space KS is selected by the user, the keyword associated with the person may be displayed in the “how” column.

  In this embodiment, as will be described later, it is possible to add a keyword to the keyword space KS referring to the RSS data RD. However, if the keyword desired by the user is already displayed, it is necessary to add the keyword. There is no. In such a case, the RSS data RD is not referred to (step S160: No), and the process proceeds to step S220 (FIG. 3). In step S220, the title setting unit 216 (FIG. 1) of the DTV 100 inputs keyword selection by the user via the instruction input unit 150. The keyword selection by the user is performed when the user operates the remote controller RC to select a keyword displayed in the keyword space KS on the title setting screen (FIG. 5). FIG. 6 shows that the keywords displayed in the “when” column and the “who” column are selected on the title setting screen. In addition, for selection of a keyword by the user, each column of the keyword space KS may be associated with each column of the numeric keypad of the three-column configuration of the remote controller RC, or a dedicated hardware button is provided on the remote controller RC. It may be done.

  In step S230 (FIG. 3), the title setting unit 216 (FIG. 1) of the DTV 100 displays title candidates on the display unit 120 in response to the keyword selection input in step S220. For example, as shown in FIG. 6, when a keyword indicating a shooting date displayed in the “when” column of the keyword space KS is selected on the title setting screen, the shooting date is displayed in the title candidate space TS. . Similarly, when a keyword indicating the name of a person displayed in the “who is” column of the keyword space KS is selected, the name is displayed in the title candidate space TS following the shooting date.

  On the other hand, when the keyword desired by the user is not displayed in the keyword space KS, it is possible to add a keyword referring to the RSS data RD. When referring to the RSS data RD (step S160: Yes), the process proceeds to step S170 (FIG. 2). In step S170, the title setting unit 216 (FIG. 1) of the DTV 100 requests the RSS data RD from the WEB server 400. The request for the RSS data RD by the title setting unit 216 is executed in response to the selection of the “RSS reference” button on the title setting screen (FIG. 6) by the user.

  Here, as described above, the RSS data RD is update information including an update date and time and a summary regarding the blog site managed by the user of the DTV 100. The URL of the RSS data RD stored in the WEB server 400 is registered in advance on the DTV 100 by the user. The title setting unit 216 requests the RSS data RD by specifying the URL of the RSS data RD registered in advance under the control of the network control unit 222.

  In step S180 (FIG. 2), the site management unit 424 (FIG. 1) of the WEB server 400 responds with the RSS data RD in response to the request in step S170.

  In step S190 (FIG. 2), the title setting unit 216 (FIG. 1) of the DTV 100 searches the RSS data RD received from the WEB server 400 for update information on the same date as the image shooting date. This search is performed by comparing the site update date included in the RSS data RD with the shooting date of the image acquired in step S130. When RSS data RD representing update information on the same day as the image shooting date is detected, a summary of the user's blog site is displayed on the title setting screen based on the detected RSS data RD. FIG. 7 shows a summary of the user's blog site based on the RSS data RD displayed in the update information space US on the title setting screen.

  If the blog site summary displayed in the update information space US (FIG. 7) on the title setting screen does not include a word that the user wants to use as a keyword, the user does not give an instruction to cut out the word. (Step S200: No), the process proceeds to Step S220.

  On the other hand, when a word that the user wants to use as a keyword is included in the summary of the blog site displayed in the update information space US (FIG. 7) on the title setting screen, the user cuts out the word. An instruction is given (step S200: Yes). FIG. 8 shows how the user instructs to cut out words. The user operates the remote controller RC to select a desired word (for example, “tennis”) in the summary of the site displayed in the update information space US, and a column (for example, a keyword space KS to which the word is added) Select the "What's wrong" column). The title setting unit 216 (FIG. 1) of the DTV 100 additionally displays a keyword in the keyword space KS in accordance with such a user instruction (step S210 in FIG. 2). In the example of FIG. 8, the keyword “tennis” is additionally displayed in the “how” column of the keyword space KS.

  The keyword added in step S210 (FIG. 2) is the target of keyword selection (step S220 in FIG. 3) by the user, like other keywords. FIG. 9 shows that the keyword (“tennis”) added in step S210 is selected by the user. When the keyword is selected by the user, as described above, the selected keyword is displayed in the title candidate space TS (step S230 in FIG. 3). FIG. 9 shows a state where the selected keyword (“tennis”) is displayed in the title candidate space TS.

  In this embodiment, one keyword is selected from each column of the keyword space KS, and title candidates are generated by arranging the three selected keywords in the same order as the columns of the keyword space KS. (See FIG. 9). At this time, words (particles) connecting the keywords may be supplemented. For example, the title setting unit 216 of the DTV 100 includes a dictionary function, and supplements particles that connect keywords when generating title candidates (step S230 in FIG. 3). In the example of FIG. 9, the particle “NO” is added between two keywords “Taro” and “Tennis”.

  When the user desires to change the title candidate displayed in the title candidate space TS in step S230 (step S240: No in FIG. 3), another keyword is displayed again with reference to other RSS data RD. (Steps S160 to S210) or other keywords can be selected (step S220). When another keyword is selected in the keyword space KS, the title candidate generated by the newly selected keyword is displayed in the title candidate space TS (step S230).

  If the user wants to confirm the title candidate displayed in the title candidate space TS in step S230 as the title of the image, the user selects the “OK” button on the title setting screen (step S240 in FIG. 3: Yes). When the title of the image is determined in this way, the processing related to image registration in step S250 and subsequent steps in FIG. 3 is automatically started.

  In step S250 (FIG. 3), the image management processing unit 210 (FIG. 1) of the DTV 100 generates title / date information indicating the title and date. The date indicated by the title / date information may be the date when the image was taken, the date when the image management process was performed (the current day), or both of them. The title / date information is generated as XML format metadata.

  In step S260 (FIG. 3), the image management processing unit 210 (FIG. 1) of the DTV 100 requests the DLNA server 300 to register an image. The image registration processing request by the image management processing unit 210 is sent to the DLNA server by using the SOAP action according to the UPnP AV upload specification under the control of the network control unit 222 and the image file IF and the title / date information (XML data). This is realized by transmitting to 300.

  In step S270 (FIG. 3), the image management DBMS 324 (FIG. 1) of the DLNA server 300 performs an image registration process. Specifically, the image file IF transmitted from the DTV 100 is stored in a predetermined area of the external storage device 330, and the title of the image specified by the title / date information of the XML data is stored in the stored image file IF. Associate a date. In step S280 (FIG. 3), the image management DBMS 324 (FIG. 1) of the DLNA server 300 notifies the DTV 100 of registration completion.

  When an image is registered in the DLNA server 300 in this way, the DTV 100 and other DLNA-compliant devices can search and view the image with reference to the date and title. The image information registered in the DLNA server 300 can also be provided to the blog site of the WEB server 400.

  As described above, the DTV 100 in the network system 10 of the present embodiment displays an image based on the image file IF. In the DTV 100, the shooting date information is acquired from the image file IF, and update information (RSS data RD) on the same day as the shooting date of the image is acquired from the WEB server 400. The acquired update information is used for setting the title of the image file IF. Specifically, a part specified by the user in the update information is adopted as at least a part of the title of the image file IF. Therefore, in this DTV 100, it is possible to reduce the character input operation when setting the image title, and to easily execute the image title setting.

  Furthermore, in this DTV 100, the shooting date of the image specified by the shooting date information can be adopted as at least a part of the title of the image. Therefore, in this DTV 100, it is possible to easily set a title that makes it easy to search for an image.

  Further, in this DTV 100, update information (RSS data RD) of the blog site of the user of the DTV 100 is used for setting the image title. In this way, by referring to the information generated based on the information generated by the user of the DTV 100 when setting the image title, there is a possibility that the referenced information includes a word that can be used for image title setting. Can be increased. Therefore, in this DTV 100, the title setting of an image can be executed more easily and more appropriately.

  In the network system 10 according to the present embodiment, the image file IF is registered in the DLNA server 300 in a state associated with the title set by the DTV 100. Therefore, an image database capable of easily managing images can be constructed.
