<2. Operation of one embodiment>
[User information setting mode]
FIG. 7 is a flowchart showing processing in the user information setting mode.
This user information setting mode is set by operating the operation unit 110. When this process is started, the event information processing unit 124 in the control unit 120 confirms whether user information is input on the display unit 150 as shown in FIG. 5 in step ST1. After the user agrees to register the information, user information such as name and birthday is entered. In step ST <b> 2, the event information processing unit 124 of the control unit 120 creates standard event data starting from the birthday input for each registered user. At this time, auxiliary data regarding the user may be entered. Next, in step ST3, the standard event data of the registered user is registered in the database in the memory unit 130.

  Similarly, the user information input at this time is registered in the memory unit 130 in step ST4. In the database of the memory unit 130, standard event data generated from user information is managed in units of users as shown in FIG.

  Events included in the standard event data include Omiya Visit, Shichigosan, entrance / entry ceremony, athletic meet, graduation / graduation ceremony, travel, etc. that occur with the growth of the user. In order to specify any one of these, it is necessary to examine the relationship with the shooting date and time, the shooting location, the residence registered as user information, and the like. It is also possible to register location information such as kindergarten or school that is passed as user information, and latitude information and longitude information are written in the event data corresponding to the location information registered in the standard event data. Events included in the standard event data are displayed as icons on the display unit 150.

  Further, the user information registered in the memory unit 130 can be deleted according to a user request. When the user information is deleted, the event data related to the deleted user recorded as the standard event data is also deleted.

  The database in the memory unit 130 stores map event data and language calendar events in addition to standard event data. Map event data includes venues and periods for events such as Rio Carnival and Aomori Nebuta Festival, as well as sports events such as the F1 Grand Prix and the four major tournaments of tennis. . The language calendar event is a language that can be set in the main body of the imaging apparatus 100, and includes annual events such as a calendar in the country (region) in which the language is used. For example, information on events such as Chinese New Year, Halloween in the United States and Europe, holidays and customary holidays, and their periods are included. In addition, this holiday or customary vacation period is referred to herein as a vacation period or holiday.

  The table structures of standard event data, map event data, and language calendar event data are as shown in FIGS. 2, 3, and 4, respectively. The event associated with the moving image / still image captured by the user is inferred from these three types of data: standard event data, map event data, and language calendar event data.

  Also, icon image data is registered in this database. The event data and icon image data are downloaded to a computer from the web on the Internet, for example, and the event data and icon image data are transferred from the computer to the video camera via a cable connection. Alternatively, event information and icon image data in the computer are stored in a memory card, and the memory card is inserted into the imaging device 100 main body. Then, event information and icon images of the imaging apparatus 100 main body are added or changed. The icon example of FIG. 6 is an example.

[Shooting mode]
FIG. 8 is a flowchart showing processing in the shooting mode.
When this process is started by operation of the operation unit 110, the event information processing unit 124 in the control unit 120 performs date and time information (year / month / day, time), position information (current position, residence), and language setting in step ST11. Get information.

  In step ST12, the event information processing unit 124 determines the priority order for narrowing down the event data from the acquired information. Then, according to the priority order, the event information processing unit 124 collates with standard event data, map event data, and language calendar event data in the database, narrows down event candidates, performs selection, and estimates an optimal event.

  When one optimal candidate is determined in this manner, the event that has become a candidate is displayed as an icon on the display unit 150 as shown in FIG. 6 in step ST13, and whether the event is associated with the user is confirmed. If this candidate event is inferred from the standard event data, it is displayed in the form of “(event name) of (name registered as user information)”.

  Step ST14 is executed to check whether or not the event is changed, step ST15 is executed to check whether or not shooting is started, and step ST16 is executed to check whether or not to end the shooting mode. .

  When an event change operation is performed by the operation unit 110, this is detected in step ST14, the event is changed to the next candidate in step ST17, and step ST14 is executed again.

  When the start of shooting is detected in step ST16, the currently selected event is recorded in the built-in memory 170 in step ST18, and shooting data is recorded in the built-in memory 170 in association with this event in step ST19. Here, if the event and the shooting data are associated with each other, the execution order of steps ST18 and ST19 may be reversed.

  When the end of shooting is detected in step ST20, the shooting mode process ends. Also, when the end of the shooting mode is detected in step ST16, the shooting mode process is similarly ended. Note that it may be confirmed whether an event is added and recorded in ST14 and ST17. By enabling the addition of events, multiple events can be recorded simultaneously.

[Event setting mode]
FIG. 9 is a flowchart showing processing in the event setting mode. Although FIG. 8 shows processing performed before shooting, the event setting mode in FIG. 9 is processing used after shooting, and is used when shooting data is already stored in the built-in memory 170.

  When processing in the event setting mode is started by operating the operation unit 110, shooting data is selected using the operation unit 110 in step ST31. When the event setting target is determined in this way, the event information processing unit 124 in the control unit 120 obtains date / time information (year / month / day, time), position information (current position, residence), and language setting information in step ST32. get.

  In step ST33, the event information processing unit 124 determines the priority order for narrowing down the event data from the acquired information. Then, according to the priority order, the event information processing unit 124 collates with standard event data, map event data, and language calendar event data in the database, narrows down event candidates, performs selection, and estimates an optimal event.

  When one optimal candidate is determined in this manner, the event that has become a candidate is displayed as an icon on the display unit 150 as shown in FIG. 6 in step ST34, and whether the event is associated with the user is confirmed. If this candidate event is inferred from the standard event data, it is displayed in the form of “(event name) of (name registered as user information)”.

  Thereafter, in step ST35, it is checked whether or not to change the event. If there is no event change, the event is recorded for the selected shooting data in step ST37, and then the event setting mode ends. Further, when an event change due to operation of the operation unit 110 is detected in step ST35, the event is changed to the next candidate in step ST36, and step ST34 is executed again. Note that it may be confirmed whether an event is added and recorded in ST35 and ST36.

  If an event has already been set for the video / still image that is the shooting data selected in the event setting mode, the user selects whether to overwrite or additionally register the event associated with this event setting mode. An event is recorded based on the selection result.

  In addition, as for the event presentation to the user, a case is shown in which one candidate event with high priority is presented and the user selects it as shown in FIG. 6, but the candidate events are displayed one after another. However, a method of presenting to the user may be used. Alternatively, all the event candidates may be displayed on the screen, and the user may select all the corresponding events and set a plurality of events for the moving image / still image to be set. At that time, an event may be presented with the top priority.

[Event guessing process]
FIG. 10 is a flowchart showing an overall outline of event estimation processing. FIG. 8 shows the process in step ST12 and FIG. 9 shows the process in step ST33.

  Official language (native language) information obtained from the position information stored in the memory unit 130 and the official language (native language) data correspondence table (use language map) from the positional information obtained by capturing the still image / video that is the event setting target. The language information set in the main body of the imaging apparatus 100 is collated in step ST41. Then, in step ST42, it is determined whether the language in which the shooting location obtained from the shooting position information is set as the official language (native language) is used in the imaging apparatus 100 main body.

  When it is determined that the language set in the imaging apparatus 100 is shooting in the country (region) used as the official language (native language), the video / still image is set in the official language of the imaging apparatus 100. Event estimation is performed as a photograph of a resident in a country (region) that uses the term (native language). Details of this estimation are shown in the flow of FIG.

  If it is determined that the language set in the imaging device 100 is not shooting in the country (region) used as the official language (native language), the language calendar event data is used to set the language in the imaging device 100. In step ST61, it is checked whether or not the shooting date corresponds to the vacation period in the selected language. In step ST62, it is determined whether the shooting date corresponds to a vacation period in the set language. If it is determined that the shooting date corresponds to a vacation period in the set language, this moving image / still image is estimated as a traveler who has visited the shooting location. Details of this estimation are shown in the flow of FIG.

  Finally, if the shooting date does not correspond to a vacation period in the set language, this moving image / still image is a place where the set language of the imaging apparatus 100 is different from the country (region) where the official language (native language) is used. Event estimation is performed as a photograph of a resident in Tokyo or a business trip by work. Details of this estimation are shown in the flow of FIG.

[Event estimation with the user as a resident in a country (region) that uses the official language (native language)]
As described above, FIG. 11 is centered on a place where an event is estimated as a photograph of a resident in a country (region) where the language set in the imaging apparatus 100 in the event estimation mode in the event estimation mode uses the official language (native language). It becomes the details of the flow.

  The event estimation order is estimated in the order of a standard event estimated from a birthday, an event at a place visited by map event data, and a calendar event based on language calendar event data.

  Using the position information obtained by capturing the still image / moving image of the event setting target, the official language (native language) information acquired using the data correspondence table from the position information to the official language (native language), and the imaging apparatus 100 main body The set language information is collated in step ST41. In step ST42, it is determined whether or not the language in which the shooting location obtained from the shooting position information is set in the main body of the imaging apparatus 100 is used as an official language (native language).

  If it is determined that the region is used as an official language (native language), the standard event data of each user created from the shooting date information and the registered birthday data of each user is obtained in step ST43. Match. In step ST44, it is determined whether there is event data that can be estimated from the standard event data of each user. In this case, an event registered in the standard event data is checked to determine whether it falls within the range of several days to several weeks before and after the corresponding date.

  If there is a corresponding event, candidate events are narrowed down in step ST45 by further checking the shooting position information and the corresponding event data. For example, if the shooting position information is a school, the event data related to the school is narrowed down. The narrowed-down event data is first displayed as candidates on the display unit 150 as shown in FIG. 6 and presented to the user in step ST46. When a corresponding event exists among a plurality of users, it is presented to the users in order from the date closest to the date of the standard event data.

  If it is determined in step ST44 that there is no corresponding event from the standard event data, the corresponding event data is collated from the shooting position information, shooting time information and map event data in step ST47. In step ST48, it is determined whether there is an event that can be estimated from the map event data. If a corresponding event exists, the corresponding event is presented to the user from the map event data in step ST49.

  When it is determined in step ST48 that there is no corresponding event from the map event data, collation is performed in step ST50 in order to check the presence / absence of the corresponding event data from the shooting date information and the language calendar event data. In step ST51, it is determined whether there is an event that can be estimated from the language calendar event data. If there is a corresponding event, the event corresponding to the set language and the shooting position is presented in step ST52 from the language calendar event data.

  If there is no corresponding event from the language calendar event data in step ST51, there is no corresponding event from the standard event data, map event data, and language calendar event data recorded in the event database, and step ST53. Is presented to the user as an “other” event for which the corresponding event did not exist.

[Estimation of an event where the user is a traveler visiting the shooting location]
As described above, FIG. 12 shows details of a flow centered on a place where an event is estimated as a traveler who has visited a video / still image shooting place to be set in the event estimation mode.

  When it is determined in step ST42 of FIG. 11 that the location obtained from the shooting position information is not a country (region) that uses the language set in the main body of the imaging apparatus 100 as an official language (native language). Event estimation is performed by performing the processing shown in FIG.

  In step ST61, it is checked whether or not the shooting date corresponds to the vacation period in the language set in the imaging apparatus 100 using the language calendar event data. In step ST62, it is determined whether the shooting date corresponds to a vacation period in the set language. Here, when it is determined that the holiday is a vacation period, the photographer estimates the event as a traveler who visits a place recorded as a shooting position. Accordingly, the event estimation order is determined based on the event at the place visited by the map event data, the calendar event at the place visited by the language calendar event data, the standard event estimated from the birthday, and the imaging device 100 based on the language calendar event data. Guess in the order of calendar events in the language set in the main unit.

  First, the shooting position information, shooting date information, and map event data are collated in step ST63. In step ST64, it is determined whether there is an event corresponding to the event information recorded in the map event data. If it is determined that there is a corresponding event, the corresponding event data from the map event data is presented to the user as an event candidate in step ST65.

  If it is determined in step ST64 that there is no event information corresponding to the map event data, the official language (native language) of the shooting location is acquired from the shooting position information, and the shooting date information and language calendar event data are stepped. Collation is performed at ST66. In step ST67, it is determined whether there is an event corresponding to the event information recorded in the language calendar event data. If it is determined that there is a corresponding event, event data corresponding to the shooting position is presented to the user from the language calendar event data in step ST68.

  If it is determined in step ST66 that there is no event information corresponding to the language calendar event data, the shooting date information and the standard event data are collated in step ST69. In ST70, it is determined whether there is an event corresponding to the event information recorded in the standard event data. If it is determined that the corresponding event exists in the standard event data, the event is further narrowed down from the corresponding event candidates from the shooting position information in step ST71. The narrowed and selected events are presented to the user as event candidates in step ST72.

  If it is determined in step ST70 that there is no event information corresponding to the standard event data, the shooting date information and language calendar event data are collated in step ST73. In step ST73, it is determined whether there is an event corresponding to the event information recorded in the language calendar event data. If it is determined that there is a corresponding event, event data corresponding to the set language is presented to the user as event candidates from the language calendar event data in step ST75.

  Finally, if it is determined in step ST74 that there is no corresponding event even in the language calendar event data, since the corresponding event does not exist in the event database in the imaging apparatus 100, the user is notified of the “other” event in step ST76. Present.

[Event estimation in which the user is a resident in a different place from the country (region) that uses the official language (native language)]
As described above, FIG. 13 is centered on a place where an event is estimated as a photograph of a resident in a place different from the country (region) where the language set in the imaging apparatus 100 uses the official language (native language) in the event estimation mode. It becomes the details of the flow.

  In step ST62 of FIG. 12, it is determined that the date obtained from the shooting date information is not a holiday period in a country (region) in which the language set in the main body of the imaging apparatus 100 is used as an official language (native language). If the event is detected, the process shown in FIG. 13 is performed to estimate the event.

  In step ST62 of FIG. 12, it is determined that the shooting date is not a holiday period in the country (region) where the language set in the imaging device 100 is used. From this determination, the photographer does not visit the position recorded as the photographing position, but estimates the event as a resident. Therefore, the event estimation order is the standard event estimated from the birthday, the event performed on the spot by the map event data, the calendar event set in the language setting by the language calendar event data, the shooting location by the language calendar event data Guess in the order of calendar events.

  The shooting date information and the standard event data are collated in step ST81. In step ST82, it is determined whether there is an event corresponding to the standard event data. If it is determined that the corresponding event exists, the candidate event is further narrowed down in step ST83 using the shooting position information. The event narrowed down in step ST83 is presented to the user as an event candidate in step ST84.

  If it is determined in step ST82 that there is no event corresponding to the standard event data, the shooting position information, shooting date information and map event data are collated in step ST85. In step ST86, it is determined whether there is an event corresponding to the map event data. When it is determined that there is a corresponding event, the corresponding event is presented to the user as an event candidate from the map event data in step ST87.

  If it is determined in step ST86 that there is no event corresponding to the map event data, the shooting date information and language calendar event data are collated in step ST88. In step ST89, it is determined whether there is an event corresponding to the language calendar event data. When it is determined that the corresponding event exists, the event corresponding to the set language is presented to the user from the language calendar event data in step ST90.

  If it is determined in step ST89 that there is no calendar event in the set language, the shooting position information and the language information are collated in step ST91. The language calendar event data obtained from the language information collated in step ST91 and the photographing date information are collated in step ST92. In step ST93, it is determined whether there is an event corresponding to the language calendar event data. When it is determined that the corresponding event exists, the event corresponding to the shooting position is presented to the user from the language calendar event data in step ST94.

  If it is determined that there is no event corresponding to the calendar event at the shooting position, the corresponding event does not exist in the event database in the imaging apparatus 100, and is thus presented to the user as an “other” event in step ST95.

[Example]
For example, when it is determined that the language setting of the imaging apparatus 100 main body is Japanese and the shooting position is somewhere in Japan, the shooting date is around the registered user's birthday. The birthday event is presented to the user as a candidate more optimal than the data included in the standard event data. In addition, if it is determined that the child age registered as the user information is shot at school in April of the age of entering the school, the entrance ceremony event is presented to the user as an optimal candidate.

  As an event that cannot be estimated from the registered user's birthday, sports watching and the like can be cited. If it is estimated from the map event data that the place is a baseball field and the shooting date is a baseball game, a baseball watching event can be cited as an optimal candidate. Finally, what is taken when it is related to the calendar such as New Year's Day, Hinamatsuri, Danno Festival, moon viewing, etc. is not judged from the user's registered birthday or shooting location and shooting date, and shooting It is estimated from the language calendar event data from the date and presented as an optimal candidate.

  Next, when it is determined that the language setting of the main body of the imaging apparatus 100 is Japanese and the shooting position is the United States, it is estimated from the language calendar event data whether the shooting date is considered to be a vacation period such as GW or summer vacation. To do. And when it is judged that it was a vacation period, an event estimates an event as a traveler. If it is estimated from the map event data that an event such as an exhibition is held from the shooting position and the shooting location, the exhibition is first presented to the user as an optimal candidate. Next, it is estimated whether it is an annual event at the shooting location (in this case, the United States). If the shooting date is around Thursday in the fourth week of November, it is estimated from the language calendar event data as a Thanksgiving event and presented to the user as an optimal candidate. Next, from the registered user information, the standard data event is inferred from the shooting date, and the optimum event is presented to the user. Finally, inference is made from language calendar event data based on the annual event and shooting date in Japanese, which is set as the language, and the optimum candidate is presented to the user.

  Finally, when it is determined that the language setting of the imaging apparatus 100 is Japanese, the shooting location is the United States, and the shooting date is not a holiday in Japan, the event is estimated as an American resident. First, event estimation is performed from standard event data generated from the shooting date and registered user information, and then event estimation is performed from map event data from the shooting position and shooting date. Next, the event is estimated from the language calendar event data as the shooting date and the annual event in Japan, and finally the event is estimated from the language calendar event data as the shooting date and the annual event in the United States.

  As described above, in this video camera, standard event data is created from user information input from the operation unit 110 and is registered in the database of the memory unit 130. The event information of the standard event data, the map event data, and the language calendar event data is selected according to the date and position information at the time of shooting, and the language set in the main body of the imaging apparatus 100 and presented to the user. Thereafter, when the user selects an appropriate event, the event is recorded in the internal memory 170 of the recording medium as an event associated with the shooting data. That is, an event can be recorded without taking time and effort. Then, the image data and the event are recorded in association with each other, so that the search becomes easy, and the user can find the moving image / still image that he / she wants to view without taking time.

[Example of change]
In step ST53 of FIG. 11, step ST73 of FIG. 12, and step ST94 of FIG. 13, a candidate “others” may be selected to avoid obvious wrong recording.

  The facility location information of the neighborhood kindergarten, school, etc. from the location information of the residence can be registered in the memory unit 130 in the same format as the event and icon download.

  In the above-described embodiment, the GPS processing unit 126 in the control unit 120 is provided to acquire position information and date / time information. However, when the position information is omitted, instead of the GPS processing unit 126 in the control unit 120. In addition, a timer unit for measuring the date and time may be provided. In this case, the timekeeping unit may be configured as a radio timepiece.

  In the above-described embodiment, it is determined whether the user is a resident or a traveler at the shooting location from the language setting of the imaging apparatus 100 main body, the shooting location, and the shooting date information, but the residence is set when the user information is registered. Thus, it is also possible to assist event estimation.

  By performing the event estimation method as described above, when the user performs shooting in various places / scenes, the time set in the imaging device 100, the language used, user information, and the imaging device 100 are acquired from the outside. The situation where the user is shooting is estimated using the position information. Then, an event is presented to the user, and one or more pieces of optimum information are added as metadata to the moving image / still image and recorded on the recording medium of the imaging apparatus 100.

  By using the language information of the imaging apparatus 100, it is possible to appropriately use the information by determining whether the user lives or travels there. The user can add an event as metadata without selecting the metadata from many choices or inputting it manually.

  In addition, the event estimation is prioritized, but the estimated event is presented to the user, the event setting is finally made according to the user's intention, and all events even if the priority is low It is possible to reduce the addition of incorrect information. By adding this metadata, the user can search for a moving image / still image to be viewed in a shorter time.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims.
