Description

  The present invention relates to a photographing apparatus such as a mobile phone terminal, a tablet terminal, a digital camera, and a video camera, and more particularly to a data storing method when storing photographed data.

  The current mobile phone terminal is equipped with a camera function as a standard feature because it allows you to shoot freely anytime and anywhere, and the storage capacity of the internal memory has increased, so you can save shooting data such as photos and videos. The number of sheets has also increased dramatically to hundreds and thousands.

  Shooting data of various photographs that the user has taken and saved up to now is a predetermined data using fixed characters and serial numbers such as the file name “NCM — 0001.JPG” in the “DCIM100” folder. The file name is automatically assigned by the rule, and it is sequentially stored in the internal memory.

  Under such circumstances, if you want to see a specific photo taken at a certain event by the user in the past (for example, a photo taken at an artist's concert), it is saved in the internal memory and automatically assigned by serial number. In this case, it was necessary to directly check the contents of each piece of data from the shooting data of the file name, which made it feel annoying.

  In the conventional technology, there is a measure to improve the file name of the shooting data that has been shot and saved by date and time. However, with that information alone, what happens to the shooting data when the date passes? In many cases, it is difficult to know whether the photo was taken, and checking the contents of the photo data file at the approximate date and time remains the same.

  Of course, if information such as “where, when, who, and what” can be added to the captured data, the search when browsing the captured data is convenient, but the more information, the more the user can associate. It is necessary to input to the shooting data, and adding information when saving the shooting data takes time to operate, and there is no improvement in terms of convenience.

  Here, Patent Document 1 discloses a system having a rule-based reasoning engine that estimates a context that is highly likely to be related to shooting data from incidental information such as shooting date and time and shooting location. In this system, the context estimated by the rule-based inference engine is assigned to the captured data, thereby facilitating management of the captured data.

JP 2002-10178 A

  However, since what is disclosed in Patent Document 1 uses a special engine called a rule-based inference engine that estimates a context that is highly likely to be related to shooting data from incidental information at the time of shooting such as shooting date and time or shooting location, It cannot be applied to all devices such as mobile phone terminals, tablet terminals, digital cameras, and video cameras.

It is a figure which shows the screen display image at the time of the process shown in FIG. It is a figure which shows the screen display image in a data folder.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing an embodiment of the photographing apparatus of the present invention.

  In this embodiment, as shown in FIG. 1, a key operation unit 3, a camera unit 4 that is a photographing unit, a memory unit 5 that is a storage unit, a liquid crystal display unit 6, a clock unit 7 that is a date and time acquisition unit, The mobile phone terminal 1 includes a communication antenna unit 8, a communication unit 9, a GPS reception antenna unit 10 and a GPS reception unit 11 that are position acquisition means, and a control unit 2.

  The key operation unit 3 performs various function settings and character input.

  The camera unit 4 captures images such as photographs and videos.

  The memory unit 5 stores various function settings, shooting data, and various databases.

  The liquid crystal display unit 6 displays various information on the liquid crystal screen.

  The clock unit 7 counts time, and acquires the shooting date and time of the image in the camera unit 4.

  The communication unit 9 transmits and receives voice and data via the communication antenna unit 8.

  The GPS receiving unit 11 acquires the position of the mobile phone terminal 1 by receiving GPS radio waves emitted from artificial satellites via the GPS receiving antenna unit 10.

  The control unit 2 performs all control processes and includes a search unit 2a and a storage control unit 2b. The search unit 2a calculates the facility name from the longitude and latitude information acquired by the GPS receiving unit 11 using the database of the memory unit 5, and the shooting date / time (date) and facility name information acquired by the clock unit 7 are obtained. Search for relevant event information automatically via the network using keywords. Then, a process of calculating the most matched information (word) from the search result is executed, and the obtained information is converted into text. The storage control unit 2b adds the searched event information or title information to the shooting data stored in the memory unit 5. In addition, the search unit 2 a may add the facility name determined using the database of the memory unit 5 to the photographing data stored in the memory unit 5. The storage control unit 2b includes “shooting date” and “title name” in the storage folder name and shooting data file name of the shooting data stored in the memory unit 5 so that the contents of the shooting data can be easily described and filed. to manage.

  In the mobile phone terminal 1 configured as described above, the shooting and storing operation of an image such as a photograph or a moving image in the camera unit 4 is used as a trigger, the shooting date and time is acquired by the clock unit 7, and the GPS receiving unit 11 The location of the mobile phone terminal 1 at the time of shooting is acquired at, and the address and corresponding facility name are determined from the longitude and latitude information at the time of shooting obtained by the GPS receiving unit 11 in the search unit 2a. As a keyword, a search is performed via the network via the communication unit 9, and event information is acquired. Then, in the storage control unit 2b, the acquired event information is automatically stored in the captured image data by providing the storage folder name or file name as the title of the image data captured by the camera unit 4. Addition becomes possible.

  Below, the process performed inside the mobile phone terminal 1 described above will be described with reference to flowcharts.

  FIG. 2 is a flowchart for explaining processing executed in the mobile phone terminal 1 shown in FIG. FIG. 3 is a diagram showing a screen display image at the time of the processing shown in FIG.

  The camera unit 4 captures an image such as a photograph or a video, and triggers an operation such as pressing the YES button to save the captured data in the memory unit 5 of the mobile phone terminal 1 (step S21, FIG. 3 ( a), FIG. 3 (b)), the control unit 2 obtains information on the shooting date and time (data creation date and time) from the clock unit 7 (step S22), and the latitude and longitude of the mobile phone terminal 1 from the GPS receiving unit 11 Is obtained. In the control unit 2, information on the facility name calculated from the conversion database stored in the memory unit 5 based on the longitude and latitude is acquired (step S23).

  Next, the search unit 2a automatically searches the event information of “what event occurred at that location at that date and time” via the network using the acquired “shooting date” and “facility name” as keywords. (Step S24, FIG. 3C). In this manner, by searching for information on “shooting date and time” and “facility name” as keywords, it is possible to search for relevant event information from existing event information.

  The control unit 2 displays the event information obtained from the search result on the liquid crystal display unit 6 and prompts the user to confirm whether or not to retain the information as the title (step S25, FIG. 3D). ).

  Then, when the fact that the searched event information is used as a title is designated by pressing the YES button (step S26), the word of the event information is converted into text data in the control unit 2 (step S27). In the storage control unit 2b, a storage folder including the shooting date and title is created (step S28). The shooting data stored in the memory unit 5 is stored in the folder with the shooting date, title, and serial number. Saved as a name (step S29, FIG. 3E).

  For example, when taking a picture using the mobile phone terminal 1 in the J-League watching game at Saitama Stadium, the shooting date and time “March 17, 2012 15:00” from the clock unit 7 and the background from the GPS receiving unit 11 are taken. The degree “(35.90465,139.716554)” information is obtained. The longitude and latitude are converted to the name of the facility, and the information “Saitama Stadium” is obtained. If “March 17, 2012” and “Saitama Stadium” are searched via the network, a lot of information on “J-League”, “Urawa”, and “Samurai” will be obtained. From this search result, the information (word word) that matches the most is calculated, and event information “J-League Urawa Battle” is obtained. It should be noted that whether or not to include the time in the keyword at the time of search can be arbitrarily set by the user.

  When this event information “J League Urawa vs. Samurai Battle” is used as the title, “20120317_J League Urawa vs. Samurai Battle Folder” is created in the memory part 5, and the shooting data is “20120317_J League Urawa vs. Samurai Battle” It is saved with the file name “_001.jpg”. At the time of subsequent photography, 001 copies are assigned sequentially and are stored sequentially in the same folder.

  FIG. 4 is a diagram showing a screen display image in the data folder.

  As a result of the above-described processing, as shown in FIG. 4, it is possible to automatically add a title indicating the contents of the event to the storage folder or the shooting data file name after the camera unit 4 captures an image. The file management of the shooting data stored in 1 is simplified, and the convenience for the user can be improved.

  The flow process will be described again.

  If the retrieved event information is not appropriate and it is unlikely that the event information can be held as a title (step S26), the user can directly input the title, thereby achieving the purpose of file management. (Step S31). Of course, in this case, it is necessary for the user to input a title by a voice recognition function provided in the mobile phone terminal 1 or direct character input using the key operation unit 3, and in terms of usability, Although it cannot be improved, convenience in file management can be improved.

  Of course, when file management is not performed (step S30), the photographed data is stored in a predetermined folder with a predetermined file name as usual (step S32).

  As described above, in the mobile phone terminal 1 equipped with the camera function and the GPS (Global Positioning System) function, when storing the shooting data of the image such as a photograph or a moving image, the serial number is assigned to a predetermined folder. Rather than saving in the image, the event information at the time of shooting is searched via the network using the shooting date / time of the image and the position information from the GPS, and the corresponding event information is used as the title, and the file name / save folder as it is By automatically assigning names, file management of image data such as pictures and videos stored in the mobile phone terminal 1 is simplified, and the convenience of the user can be improved.

(Other embodiments)
In the above-described embodiment, an example of searching for event information via a network has been described as an example. However, for example, a camera shooting scene in a personal schedule other than a public event such as a family trip or a children's athletic meet There are also multiple possibilities. In this case, it is assumed that event information is hardly obtained even when searching via the network.

  Therefore, it is conceivable to search for relevant event information from event information input to the schedule function of the mobile phone terminal 1 and stored in the memory unit 5. For example, assume that Tokyo Disneyland is entered as a family trip in the schedule function. When the shooting date and time is the date and time of the family trip and the facility name obtained from GPS is Tokyo Disneyland, the title input to the schedule function as the family trip is added as the folder name and file name. As a result, the same file management as described above can be performed on the shooting data of the image shot by the camera unit 4 using the event information stored in the mobile phone terminal 1.
