  Embodiments of the present invention will be described with reference to the drawings. As illustrated in FIG. 1, the photographic image processing apparatus 1 according to the embodiment of the present invention includes a control unit 11, a storage unit 12, an operation unit 13, a display unit 14, and a communication unit 15. It is configured. In the present embodiment, the photographic image processing apparatus 1 is connected to a database 2 that holds photographic image data via a network. In this example, the database that holds the photographic image data is connected to the photographic image processing apparatus 1 via a network. However, the present embodiment is not limited to this, and the database 2 is stored in the storage unit 12. May be. Further, the database 2 used by the photographic image processing apparatus 1 is not limited to one but may be a plurality.

  In the present embodiment, the photographic image data stored in the database 2 includes information on the shooting location (L) and the shooting date and time (T) as illustrated in FIG. Additional information (A) is associated with the data.

  The control unit 11 is a program control device such as a CPU (Central Processing Unit) and operates according to a program stored in the storage unit 12. In the present embodiment, the control unit 11 functions as a receiving unit that accepts photographic image data including a shooting location and a shooting date and time as a processing target. In addition, the control unit 11 acquires the shooting date and the shooting location of the photographic image data received as the processing target. And the control part 11 is a photograph including the shooting date and time and the shooting location in which the difference between the shooting date and the shooting location acquired from the processing target photo image data is within a predetermined range among the photographic image data held in the database 2. Set image data as a search target, acquire additional information associated with the photo image data set as the search target, select additional information satisfying a predetermined condition from the acquired additional information, and select the selected additional It functions as a means for storing information in association with a photographic image to be processed. Details of the operation of the control unit 11 will be described later.

  The storage unit 12 is a memory device or the like and holds a program executed by the control unit 11. The storage unit 12 also functions as a work memory for the control unit 11. In an example of the present embodiment, the storage unit 12 may hold photographic image data in association with additional information.

  The operation unit 13 is a receiver that receives a signal from a pointing device, a keyboard, or a remote controller. The operation unit 13 receives an instruction operation from the user and outputs the content of the instruction operation to the control unit 11.

  The display unit 14 is, for example, a display or an interface of a television receiver. The display unit 14 outputs the instructed image to the display or the television receiver in accordance with the instruction input from the control unit 11.

  The communication unit 15 is a network interface or the like, and outputs data received via the network to the control unit 11. The communication unit 15 sends various data to the instructed destination via the network in accordance with the instruction input from the control unit 11.

  Next, the operation of the control unit 11 according to an example of the present embodiment will be described. Functionally, the control unit 11 according to the present embodiment functionally includes a receiving unit 21, a search target setting unit 22, an additional information acquisition unit 23, a selection unit 24, and an association unit 25 as illustrated in FIG. It is comprised including.

  The receiving unit 21 receives photographic image data including a shooting location and a shooting date and time as a processing target. The search target setting unit 22 reads the shooting location and the shooting date / time included in the photographic image data to be processed. The search target setting unit 22 accesses the database 2 and includes information on the shooting date and time that is within a predetermined range from the shooting date and time read from the photographic image data that is the processing target. The photographic image data including the information on the photographic location whose difference from the photographic location read from the photographic image data is within a predetermined range is extracted from the photographic image data held in the database 2. The search target setting unit 22 sets the extracted photographic image data as a search target.

  Specifically, the predetermined range related to the shooting date and time and the predetermined range related to the shooting location may be set in advance. For example, the predetermined range related to the shooting date and time may be set to 12 hours, and the predetermined range related to the shooting location may be set to 2 km. In this way, the information on the shooting date and time that is within 12 hours is included in the difference between the shooting date and time of the photographic image data to be processed, and the difference from the shooting location of the photographic image data to be processed is 2 km. The photographic image data including the shooting location information within the range is selected from the database 2 as a search target.

  The additional information acquisition unit 23 acquires additional information associated with the photographic image data set as the search target and outputs the additional information to the selection unit 24. The selection unit 24 selects additional information satisfying a predetermined condition from the additional information acquired by the additional information acquisition unit 23 and outputs the selected additional information to the association unit 25. Here, for example, the predetermined condition may be that the appearance frequency is higher than a predetermined threshold value.

  As an example, it is assumed that “XX River Kawahara” appears twice and “Fireworks Festival” appears six times in the additional information associated with the photo image data selected as the search target. At this time, if the threshold value is set to “4”, the selection unit 24 selects and outputs the additional information of “Fireworks display”.

  The associating unit 25 associates the additional information output from the selecting unit 24 with the photographic image data to be processed and stores it in a predetermined recording destination such as the storage unit 12.

The photographic image processing apparatus 1 of the present embodiment is configured as described above and operates as follows. In the following example, the database 2 includes at least a picture Pa of a bird photographed in the Y river field of the XX river on August 10, 2012, and pictures Pb, Pc, Pd, Pe of a fireworks display 2012. A picture of the fishing tournament, Pf, Pg, Ph, Pi, taken on August 17th in the Y River on the XX River, and another on August 10th in Z Town, more than 2 km away from the River XX River It is assumed that photos Pj and Pk of the fireworks display are stored. Further, Pa to Pk have additional information as
Pa: XX river Y Kawahara, bird photos Pb, Pc, Pd: XX river Y Kawahara, fireworks display Pe: XX river Y Kawahara, fireworks display, Y Kawarabashi distant view Pf, Pg, Ph, Pi: XX river Y Kawahara, Assume that information such as fishing tournaments Pj, Pk: Z town, fireworks display is associated.

  As shown in FIG. 4, the photographic image processing apparatus 1 according to the present embodiment receives, as a processing target, photographic image data Pr photographed on the Y riverbank of the XX river on August 10, 2012 from a user ( S1), the photographing date and time Rd and the information of the photographing location Rl included in the accepted photographic image data Pr are acquired (S2).

  The photographic image processing apparatus 1 sets the minimum value Rd−ΔD and the maximum value Rd + ΔD as the shooting date / time range using the acquired shooting date / time Rd, and uses the acquired shooting location Rl to set a range of ΔL around Rl. Is set as the shooting location range (S3).

  The photographic image processing apparatus 1 includes the photographic image data stored in the database 2 within the photographic date / time range in which the included photographic date / time is set, and the included photographic location is set. Photo image data in the shooting location range is extracted as a search target (S4). Here, when ΔD is set to 24 hours and ΔL is set to 2 km, photographic image data Pa, Pb, Pc, Pd, and Pe are extracted from the database 2.

  Then, the photographic image processing apparatus 1 checks the appearance frequency of the additional information associated with the photographic image data extracted as the search target (S5). In the above example, “XX River Y Kawara” is associated with the photographic image data Pa, Pb, Pc, Pd, Pe, so the appearance frequency is “5”, and “Fireworks Festival” is the photographic image data Pb, Pc, The appearance frequency is “4” because it is associated with Pd and Pe, and the appearance frequency is “1” because “bird photo” and “Y Kawarabashi distant view” are associated only with the photographic image data Pa and Pe, respectively. "

  The photographic image processing apparatus 1 selects additional information that appears with an appearance frequency that exceeds (for example, exceeds) a predetermined threshold value Tt (for example, “4”) (S6). Here, “XX river Y Kawara” (appearance frequency 5) and “fireworks display” (appearance frequency 4) are selected as additional information that appears when the threshold value Tt = “4” or more.

  The photographic image processing apparatus 1 stores the additional information selected here, “XX River Y Kawara” and “Fireworks Display” in the storage unit 12 in association with the photographic image data Pr to be processed (S7).

  Although the additional information is selected here based on the appearance frequency, the present embodiment is not limited to this. For example, if there is an individual who has taken many photos of “flowers” in the vicinity of the fireworks display, regardless of the fireworks display, “flowers” may be selected as additional information. obtain. Therefore, instead of the appearance frequency, for each additional information, the number of photographers who photographed the photographic image data associated with the additional information is calculated, and the additional information is selected to be higher than a predetermined threshold value Tt_p. Also good.

  In this example, it is assumed that the photographer image data includes photographer information (the photographer information may not be the photographer name but may be information on the imaging device such as the camera model name). For example, in the above example, it is assumed that the pictures Pb, Pc, Pd, and Pe of the fireworks display are photographs taken by different photographers (who visited the fireworks display). On August 10, 2012, 15 photograph image data taken by one photographer who is within 2 km from the Y river in the XX river and associated with the additional information “flower” are stored in the database 2. Suppose that In this case, the number of photographers of photographic image data associated with the additional information of “Fireworks” is 4, and the number of photographers of photographic image data associated with “flowers” is 1. For example, the threshold value Tt_p is set to If “4 or more” is set, the additional information of “flower” is not selected, but the additional information of “fireworks display” is selected. The additional information of the selected “fireworks display” is recorded by the photographic image processing apparatus 1 in association with the photographic image data Pr to be processed.

  Furthermore, in an example of the present embodiment, the predetermined range related to the shooting date and time and the shooting location when setting the search target may be determined based on the number of photographers of the photographic image data held in the database 2. Specifically, the predetermined range may be set narrower as the number of photographers increases.

  Specifically, the photographic image processing apparatus 1 sets in advance initial values Dini and Lini of a predetermined range of shooting date and time and shooting location. The photographic image processing apparatus 1 performs the process illustrated in FIG. 5 instead of the processes S3 and S4 illustrated in FIG. That is, the photographic image processing apparatus 1 initially sets ΔD = Dini and ΔL = Lini, and uses the shooting date / time Rd acquired in step S2 in FIG. 4 as the shooting date / time range with the minimum value Rd−ΔD and the maximum value Rd + ΔD. In addition, using the shooting location Rl acquired in the process S2 in FIG. 4, a range of ΔL centering on Rl is set as the shooting location range (S11).

  The photographic image processing apparatus 1 includes the photographic image data stored in the database 2 within the photographic date / time range in which the included photographic date / time is set, and the included photographic location is set. Photo image data within the shooting location range is extracted as a search target (S12), and it is checked whether or not the extracted search target satisfies a predetermined condition (S13). Here, if the extracted search target satisfies a predetermined condition (if Yes), the photographic image processing apparatus 1 shifts the processing to step S5 in FIG.

  If the extracted search target does not satisfy a predetermined condition (in the case of No), the photographic image processing apparatus 1 changes at least one of ΔD and ΔL by a predetermined method described later, and also in FIG. The minimum value Rd−ΔD and the maximum value Rd + ΔD are set as the shooting date / time range by using the shooting date / time Rd acquired in the process S2, and the shooting location R1 acquired in the process S2 in FIG. The range of ΔL is set as the shooting location range (S14). And it returns to process S12 and continues a process.

  Here, the condition in step S13 may be, for example, a condition as to whether or not the number of photographic image data extracted as a search target has exceeded a predetermined number threshold. If the photographer's information is included in the photographic image data (the photographer's information is not the photographer's name but may be the information of the imaging device such as the model name of the camera), the above condition is the search It may be a condition as to whether or not the number of photographers of the photographic image data extracted as the target exceeds a predetermined number threshold.

  Moreover, the adjustment method of ΔD or ΔL in step S14 may be as follows, for example. That is, if the number of photographic image data extracted as search targets in step S13 does not exceed the predetermined number threshold Tmin, the photographic image processing apparatus 1 sets the predetermined number Lincl to the current ΔL. Add and update ΔL. Alternatively, if the number of photographers of the photographic image data extracted as the search target in process S13 does not exceed the predetermined number of people threshold value Tp_min, the photographic image processing apparatus 1 sets the current ΔL in advance. ΔL may be updated by adding the existing number Lincl. Alternatively, ΔD may be updated by adding a predetermined number Dincl to ΔD instead of ΔL, or each predetermined number of Lincl and Dincl may be added to ΔL and ΔD to update each. Also good.

  Further, the condition in the process S13 may be a condition as to whether or not the number of photographic image data extracted as a search target exceeds a predetermined maximum number threshold Tmax. When the number of photographic image data extracted as a search target exceeds a predetermined maximum number threshold Tmax, the photographic image processing apparatus 1 in process S14 determines a number r (0 < ΔL may be updated by multiplying by r <1). Alternatively, if the number of photographers of the photographic image data extracted as the search target in process S13 exceeds the predetermined maximum number of people threshold value Tp_max, the photographic image processing apparatus 1 sets the current ΔL to a predetermined value. ΔL may be updated by multiplying the number r (0 <r <1). Alternatively, ΔD may be updated by multiplying ΔD by a predetermined number rd (0 <rd <1) instead of ΔL, or ΔL and ΔD may be respectively predetermined numbers r, rd ( Each may be updated by adding (0 <r, rd <1).

  Further, in order to cope with the case where ΔD and ΔL are infinitely increased or the case where ΔD and ΔL are too small, ΔD and ΔL adjusted in step S14 are predetermined ranges ΔDmin to ΔDmax and ΔLmin to ΔLmax, respectively. 4 may be shifted to step S5 in FIG. 4 at that time.

  Further, the ranges ΔDmin to ΔDmax and ΔLmin to ΔLmax, or Dincl, Lincl, r, rd, or Tmin, Tmax, Tp_min, Tp_max when performing the processing illustrated in FIG. 5 are performed according to the tag information included in the extraction information. May be different.

  As an example, the photographic image processing apparatus 1 of the present embodiment may store a data table in which values such as Dincl and Lincl are associated with each predetermined additional information classification. In this case, the photographic image processing apparatus 1 performs processing as follows. That is, as illustrated in FIG. 6, when photographic image data Pr is accepted as a processing target from a user (S21), information on the photographing date and time Rd and the photographing location Rl included in the accepted photographic image data Pr is acquired. (S22).

  Further, the photographic image processing apparatus 1 initially sets ΔD = Dini and ΔL = Lini, sets the minimum value Rd−ΔD and the maximum value Rd + ΔD as the shooting date / time range using the shooting date / time Rd acquired in the processing S22, and Using the acquired shooting location Rl, a range of ΔL centering on Rl is set as the shooting location range (S23).

  The photographic image processing apparatus 1 includes the photographic image data stored in the database 2 within the photographic date / time range in which the included photographic date / time is set, and the included photographic location is set. Photo image data within the shooting location range is extracted as a search target (S24). Then, it is checked whether or not the extracted search target satisfies a predetermined condition (S25). Here, if the extracted search target satisfies a predetermined condition (if Yes), the photographic image processing apparatus 1 uses the appearance frequency for the additional information associated with the photographic image data extracted as the search target. (S26).

  The condition in this process S25 may be, for example, a condition as to whether or not the number of photographic image data extracted as a search target has exceeded a predetermined number threshold. If the photographer's information is included in the photographic image data (the photographer's information is not the photographer's name but may be the information of the imaging device such as the model name of the camera), the above condition is the search It may be a condition as to whether or not the number of photographers of the photographic image data extracted as the target exceeds a predetermined number threshold.

  The photographic image processing apparatus 1 selects additional information that appears with an appearance frequency exceeding a predetermined threshold value Tt (eg, not less than the threshold value Tt) (S27). Then, the photographic image processing apparatus 1 associates the selected additional information with the photographic image data Pr to be processed (S28) and stores it in the storage unit 12.

  On the other hand, if the extracted search target does not satisfy the predetermined condition in the process S25 (No), the photo image processing apparatus 1 takes out additional information associated with the photo image data extracted as the search target. (S29).

  The photographic image processing apparatus 1 classifies the extracted additional information into one of predetermined additional information classifications (S30). Various methods can be used as this classification method. For example, each of the additional information classifications (which may be character strings) such as “event” and “store name” is classified into the additional information classification. The data associated with the character string of the additional information to be used is used, and the photographic image processing apparatus 1 refers to this data and extracts the additional information classification associated with each of the extracted additional information. . The data referred to by the photographic image processing apparatus 1 is so-called thesaurus data in which words similar to each other are associated with typical words (representing additional information classification).

  The photographic image processing apparatus 1 sequentially selects the additional information classification obtained in step S30 as the attention additional information classification (S31), and performs the additional information acquisition process shown in FIG. 7 for the attention additional information classification (S32). ).

  That is, the photographic image processing apparatus 1 reads values such as Dincl and Lincl associated with the attention additional information classification with reference to the data table as additional information acquisition processing (S41).

  For example, the photographic image processing apparatus 1 generates a temporary ΔLtmp corresponding to the current ΔL, and sets ΔLtmp = ΔL. The photographic image processing apparatus 1 adds Lincl read in step S41 to ΔLtmp (S42). The photographic image processing apparatus 1 generates a temporary ΔDtmp corresponding to the current ΔD, and sets ΔDtmp = ΔD. The Dincl read in step S41 may be added to update ΔDtmp. Further, the photographic image processing apparatus 1 may update each of the ΔLtmp and ΔDtmp by adding the Lincl and Dincl read in step S41.

  The photographic image processing apparatus 1 uses the minimum value Rd−ΔDtmp and the maximum value Rd + ΔDtmp as the shooting date / time range by using ΔLtmp, ΔDtmp obtained in step S42 and the shooting date / time Rd acquired in step S22 for the attention additional information classification. Using the acquired shooting location Rl, the range of ΔLtmp centered on Rl is set as the shooting location range, and the shooting date and time included in the photo image data stored in the database 2 is set. The photograph image data within the shooting date and time range and the included shooting location is in the set shooting location range is extracted as a search target (S43). Then, it is checked whether or not the extracted search target satisfies a predetermined condition (S44). The conditions here may be the same as the conditions in step S25. Here, if the extracted search target satisfies a predetermined condition (if Yes), the photographic image processing apparatus 1 is associated with the photographic image data extracted as the search target. Of the additional information, the appearance frequency of the additional information classified into the attention additional information classification is examined (S45). Then, the photographic image processing apparatus 1 selects additional information (additional information classified into the attention additional information classification) that appears with an appearance frequency exceeding a predetermined threshold Tt (for example, greater than or equal to the threshold Tt). Output (S46). If there is no additional information that appears with an appearance frequency exceeding the threshold value Tt (additional information classified into the attention additional information classification), nothing is output in the process S46, and the additional information acquisition process is terminated.

  On the other hand, if the search target extracted in the process S44 does not satisfy the predetermined condition (if No), the process returns to the process S42 to continue the process. Further, in order to cope with the case where ΔDtmp and ΔLtmp are infinitely increased or the case where ΔDtmp and ΔLtmp are too small, ΔDtmp and ΔLtmp adjusted in step S42 are predetermined ranges for each of the attention additional information classifications. If the value deviated from ΔDmin to ΔDmax and ΔLmin to ΔLmax), the process may proceed to step S46 at that time.

  The photographic image processing apparatus 1 performs the additional information acquisition process illustrated in FIG. 7 for each additional information classification obtained in process S30 (loops), and outputs the additional information as photographic image data to be processed. It is associated with Pr (S33) and stored in the storage unit 12.

  According to this process, if it is an “outdoor event” such as a fireworks display, the time range is at most about 2 hours, and the geographical range that can be viewed is considered large. The range spans about two weeks, but the geographic range is considered small. In addition, if it is a “store” such as a ramen shop, there is no time range and the geographical range is considered to be quite small. Therefore, for the additional information classification “outdoor event”, Lincl is set relatively large, and when ΔDmax is determined, it is set in the data table as a value representing about a few hours. For the additional information classification “store”, Dincl is set to be relatively large, and ΔLmax may be set in the data table as a value representing about 20 meters.

  In the above description of the present embodiment, the photographic image processing apparatus 1 has added information associated with the photographic image data stored in the database, and is additional information that matches a predetermined prohibited word. Even if the appearance frequency is higher than the predetermined threshold value Tt, it may be controlled not to select. Specifically, the prohibited word here may be added at any time and anywhere, such as “sunny”, “rain”, and “sky”. Thereby, the additional information that can be set anytime and anywhere is added to the photographic image data to be processed, thereby reducing the chance that the unintended additional information is associated.

  Further, the photographic image processing apparatus 1 of the present embodiment is not limited to the examples described so far. For example, the photographic image processing apparatus 1 according to the present embodiment stores, for each additional information associated with photographic image data stored in advance in a database, as a range database in association with range information indicating a shooting location and a shooting date / time range. It may be recorded at 12 mag.

  Specifically, as illustrated in FIG. 8, this range database has a date and time of “X fireworks display”: “* / 8/12; a range from 19:00 to 21:00”, a place: “1. Range information such as “within 5 km range” (where “*” means an arbitrary value) is associated. Also, “BBQ” is associated with date / time: “* / 7/20 to * / 8/31; range from 12:00 to 18:00”, location: “within 2 km range from Y Kawahara” ... It will be something like that.

  In this example, the photographic image processing apparatus 1 operates as illustrated in FIG. When the photographic image processing apparatus 1 accepts the photographic image data Pr as a processing target from the user (S51), the photographic image processing apparatus 1 acquires the shooting date / time Rd and the information of the shooting location Rl included in the received photographic image data Pr (S52). .

  The photographic image processing apparatus 1 refers to the range database and searches for the date / time range including the shooting date / time Rd and the shooting location R1 acquired in step S52 and the range information representing the location range (S53). As a result of this search, the photographic image processing apparatus 1 acquires, from the range database, additional information associated with the found range information (which may be plural) (S54).

  The photographic image processing apparatus 1 stores the additional information acquired here in the storage unit 12 in association with the photographic image data Pr to be processed (S55).

  As an example, when the range database is the one illustrated in FIG. 8, the shooting date and time Rd included in the photographic image data Pr received in the process S51 is “2012/7/31, 14:00”, and the shooting location Rl is “Y Kawahara. ”. At this time, the shooting date / time Rd and shooting location Rl are the range information “* / 7/20 to * / 8/31; range from 12:00 to 18:00” associated with “barbecue”, location: “from Y Kawahara Since it is included in “2 km range”, the photographic image processing apparatus 1 acquires “barbecue” associated with the range information as additional information, and uses the acquired character string of “barbecue” for the photographic image data Pr. It is stored in association as additional information.

  This range database may be generated artificially based on the photographic image data stored in the database 2, or generated without human operation based on the photographic image data stored in the database 2. May be.

  Specifically, when generating without manual operation, additional information, shooting date and time, and shooting location information included in the photographic image data stored in the database 2 are analyzed statistically or by pattern recognition processing, You can get a database. There are various specific processing contents for this purpose, and widely known statistical processing or pattern recognition processing can be used. Therefore, detailed description thereof is omitted here.
