  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
First, a first embodiment of the present invention will be described.

  FIG. 1 is a block diagram showing a configuration of a digital camera which is a portable terminal device according to the first embodiment of the present invention.

  In FIG. 1, a digital camera 10 includes a control unit 11, a photographing unit 12, a recording unit 13, a display unit 14, a position information acquisition unit 15, a calculation unit 17, a determination unit 18, and a communication unit. 19 and a clock unit 20.

  The control unit 11 controls the entire digital camera 10 in accordance with a user instruction. This control unit has functions of a calculation control unit, a determination control unit, a determination start control unit, and a second determination start control unit.

  The imaging unit 12 is a photographing unit for photographing an image of a subject (not shown). The recording unit 13 records the image captured by the imaging unit 12 and the position information acquired from the position information acquisition unit 15. The display unit 14 has a function as a processing unit that performs specific processing such as displaying an image captured by the imaging unit 12 and a message to the user, and a notification unit that notifies the message.

  The position information acquisition unit 15 is for receiving radio waves from GPS and acquiring the current position of the device. The calculation unit 17 is a calculation unit for calculating an average action area from the position information recorded and accumulated in the recording unit 13. The determination unit 18 compares and determines the average action area (substantially moving area) calculated by the calculation unit 17 and the current position, that is, position information (current position) newly acquired by the digital camera 10. Is determined to be inside or outside the approximate moving area. The communication unit 19 is communication means for performing communication with an external device (not shown). The clock unit 20 is a means for acquiring the current time as time information at the position acquired by the position information acquisition unit 15.

  Next, with reference to the flowchart of FIG. 2, the operation when the user sets the message notification function for prompting photographing in the digital camera 10 configured as shown in FIG. 1 will be described. The message notification function for prompting photographing can be set on / off in the menu of the digital camera 10.

  First, in step S1, the position information acquisition unit 15 receives radio waves from GPS at certain time intervals and acquires current position information. The acquired current position information is recorded and accumulated in the recording unit 13.

  FIG. 3 shows the position information data recorded and accumulated in the recording unit 13.

  Next, in step S2, it is determined whether a predetermined number of times of position information or a predetermined period of position information has been recorded and accumulated. Here, when the position information has been recorded and accumulated more than a predetermined number of times or for a predetermined period, the process proceeds to step S3. On the other hand, when the position information has not been recorded and accumulated for a predetermined number of times or for a predetermined period in step S2, the process proceeds to step S7 described later.

  In step S3, the position information data recorded and accumulated in the recording unit 13 is read out by the control unit 11, and the average action area of the user is calculated by the calculation unit 17. Next, in step S4, the determination unit 18 calculates the distance between the current position information obtained by the position information acquisition unit 15 and the average action area calculated in step S3, and compares them.

  In step S5, the determination unit 18 determines whether the current position information compared in step S4 and the average action area are separated by a predetermined distance or more (inside or outside the moving area). Is done. As a result of this determination, if it is determined that the distance is greater than or equal to the predetermined distance (outside the moving area), the process proceeds to step S6, and if not (inside the moving area), the process proceeds to step S7 described later.

  In step S6, since it is presumed that the user is not in a place where he / she does not normally visit, a message prompting photographing is displayed on the display unit 14 as a processing unit (notification unit). Thereafter, the process proceeds to step S7 to enter a standby state, and after a predetermined time has elapsed, the process proceeds to step S1 again to acquire position information.

  In step S1, the time interval for acquiring the position information from the GPS may be set by the user. In step S4, the user may be able to set a predetermined distance used for comparison determination between the current position and the average action area.

  FIG. 4 shows a modification of the first embodiment of the present invention. In the digital camera 10 having the configuration shown in FIG. 1, it is determined whether or not shooting has been performed within a predetermined period from the present time. It is a flowchart for demonstrating the case where determination of whether the message which urges | shoots imaging | photography is notified within the predetermined period was added.

  The processing operations of steps S11 to S13 and steps S18 to S21 in the flowchart of FIG. 4 are the same as steps S1 to S3 and steps S4 to S7 of the flowchart of FIG. The description will be omitted here.

  When the position information data recorded and stored in the recording unit 13 is read out in step S13 and the average action area of the user is calculated by the calculation unit 17, in the subsequent step S14, the final notification time of the message T1 is acquired. Then, in step S15, it is determined whether or not a message prompting photographing is notified within a predetermined period from now. That is, it is determined whether or not the current time is a time when a predetermined time has elapsed from T1 acquired in step S14.

  Here, if the predetermined time has not elapsed, the process proceeds to step S21. If the predetermined time has elapsed, the process proceeds to step S16, and the final photographing time T2 is acquired. Next, in step S17, it is determined whether or not photographing has been performed within a predetermined period from the present time.

  As a result, if the predetermined time has not elapsed, the process proceeds to step S21, and if the predetermined time has elapsed, the process proceeds to step S18. In step S18, the distance between the current position information and the average action area is calculated, and both are compared.

  Here, the average action area calculation method in step S3 in the flowchart of FIG. 2 will be described with reference to FIG.

  FIG. 5A is a diagram showing a distribution of position information at a certain time T1 when position information is acquired for 10 days. Based on the distribution of position information, each point is divided into one or more groups. For group division, the distance between each two points is calculated, and if the distance is equal to or smaller than a certain threshold value (inside the moving area), the two points belong to the same group.

  When calculating an average action area, all the position information recorded and accumulated in the recording unit 13 may be used, or only position information for a specific period is used, or only a specific day of the week, weekdays, and holidays only. , Etc. may be used.

  FIG. 5B is a diagram illustrating a result of group division. In this case, it is divided into four groups, Group A, B, C and D. The area (individual area) indicated by these four groups is regarded as the average action area of the user at time T1. The area indicated by the group is a range in which regions that are equal to or less than a threshold distance are overlapped with each point belonging to the group as the center.

  As a method for calculating the distance between each two points, the distance may be calculated from latitude and longitude. Alternatively, when the data received from the GPS includes information on the ground speed and the traveling direction, the values may be calculated using those values.

  Furthermore, the threshold for calculating the distance between each two points and the threshold for determining the area indicated by the group may be constant values in all the position information. Alternatively, the threshold may be increased as the date is newer, or when altitude information is included in data received from GPS, weighting such as changing the threshold according to altitude may be performed.

  Moreover, the range within the threshold value of each point does not need to be a circular area centered on each point, map information is recorded in the recording unit 13, and the map information is referred to at each point where the position information is acquired. A threshold value in accordance with the map information may be set.

  As an example of setting the threshold value, when the point indicated by the position information is determined to be on the road by the map information, the threshold value is set along the road. For example, as shown in FIG. 6A, if the position at a certain time is a point 26, the range 27 within the threshold value of this point 26 is a range along the road 25. If it is determined that there is a building in the vicinity, the threshold is set while avoiding the building. For example, as shown in FIG. 6B, if the position at a certain time is a point 30, the range 27 within the threshold of this point 30 is a range along the road 25 and the building 29.

  Next, a method for comparing and determining the current position and the average action area in step S4 will be described.

  When the distance between the current position information and each group is calculated and the distance is equal to or smaller than the threshold value, it is determined that the current position is within the average action area. On the other hand, when it is larger than the threshold, it is determined that the current position is outside the average action area.

  For calculating the distance between the current position and each group, the distance between each point belonging to the group may be calculated, or the distance between the point representing the group (for example, the center of gravity) may be calculated.

  FIG. 5C is a diagram illustrating a case where the distance between the current position and Group A is equal to or smaller than the threshold value and it is determined that the current position belongs to Group A. FIG. 5D is a diagram showing a case where the distances between the current position and Groups A, B, C, and D are larger than the threshold and are determined not to belong to any group.

  It should be noted that the distance between the current position and all groups may be determined, or only when there are a certain number or more of points belonging to the group (for example, in the case of FIGS. 5A to 5D, Group A, B) may be regarded as the average action area of the user, and the distance to these may be determined.

  Next, a modified example of the determination method of the current position and the average action area will be described with reference to the flowchart of FIG.

  First, in step S31, a counter C (not shown) in the control unit 11 is initialized. In the subsequent step S32, position information at time T is acquired, where T (first time) is the current time for determination, and ΔT is the position information acquisition interval. Further, when the average action area (first approximate movement area) is calculated in step S33, the current position at time T and the average action area are compared in step S34. Then, in step S35, it is determined whether or not the current position and the average action area are separated by a predetermined distance or more.

  As a result, when it is determined that it belongs to the average action area, the process proceeds to step S36 and the counter C is incremented by one. Next, in step S37, the value of the counter C is determined. Here, in the case of C ≦ 1, the process proceeds to step S42 and waits until ΔT elapses, and then the process proceeds to step S32 to acquire position information at time T + ΔT (second time). . Thereafter, after the average action area (second approximate movement area) is calculated again in step S33, the current position and the average action area are compared and determined in steps S34 and S35.

  If it is determined again in step S35 that the current position belongs to the average action area, the counter C is incremented by 1 in step S36. In step S37, the value of the count C is determined again.

  Here, in the case of counter C> 1, that is, when it is determined that the current position belongs to the average action area twice consecutively, the process proceeds to step S38, where the position between time T and T + ΔT is determined. A transition is sought and similarity with the behavior pattern is determined. As a result, if it is determined in step S39 that they are not similar, the process proceeds to step S40, the counter C is initialized, and a message prompting photographing is displayed on the display unit 14 in step S41. On the other hand, if it is determined in step S39 that they are similar, the process proceeds to step S42.

  In step S35, if it is determined that it does not belong to the average action area, the process proceeds to step S40, and the counter C is initialized. Next, in step S41, a message prompting the user to shoot is notified. In step S42, after waiting for time ΔT, the process proceeds to step S32.

  Next, a method for determining the similarity with the action pattern by obtaining the transition of the position in step S38 of the flowchart of FIG. 7 described above will be described.

  First, for each date, a group of areas to which positions at time T and T + ΔT belong is obtained.

  FIG. 8 shows a group of areas to which positions at 10 days T and T + ΔT belong, (a) shows a group of areas to which a position at time T belongs, (b) It is the figure which showed the group of the area to which the position in time T + (DELTA) T belongs. FIG. 9 is a table summarizing the area groups to which the positions at time T and T + ΔT for 10 days belong.

  The group of areas to which the position at today's time T and time T + ΔT belongs is compared with the data shown in FIG. If a match is found, the movement from time T to time T + ΔT is determined to be similar to the average behavior pattern. On the other hand, if no match is found, it is determined that there is no similar behavior pattern for movement from time T to time T + ΔT.

  For example, as shown in FIGS. 10A, 10B and 10C, when the group belonging from time T to time T + ΔT changes from A → A ′, No. in the table shown in FIG. It is the same as 1 and 2, and is determined to be similar to the previous behavior pattern.

  Also, as shown in FIGS. 10D, 10E, and 10F, when the group belonging from time T to time T + ΔT changes from A → B ′, the table shown in FIG. 9 is the same. Does not appear and is determined to be different from the normal behavior pattern.

  As described above, even when the positions at the time T and the time T + ΔT belong to the average action area, it is possible to better estimate the user's action by considering the movement between ΔT.

  In addition, as a method for notifying the user of a message for prompting photographing in step S6 of the flowchart of FIG. 2, the method shown in FIG. In other words, a message is displayed on the display unit 14 of the digital camera 10 to prompt photographing. Further, the photographing of the digital camera 10 may be urged by lighting or blinking, or by sounding an alarm sound.

  If communication with an external device (not shown) is possible using the communication unit 19, the external device may be notified. As a method of notifying the external device, a method of displaying a message on the display unit of the external device through a wired connection such as USB, or lighting / flashing the LED may be used. Alternatively, as shown in FIG. 11 (b), a method such as sending a mail to the external device 36 using the radio 35 can be used. In this case, for example, it may be displayed on the display unit 37 of the external device 36.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  FIG. 12A shows a configuration of the second exemplary embodiment of the present invention, and is a block configuration diagram of a communication system that performs communication between a digital camera and a server device.

  In the second embodiment, the configuration and basic operation of the digital camera are the same as the configuration and operation of the digital camera of the first embodiment shown in FIGS. In these configurations and operations, the same parts are denoted by the same reference numerals, and the illustration and description thereof will be omitted, and only different operations will be described.

  In FIG. 12A, the digital camera 10 a and the server device 40 are connected via a network 38.

  The control unit 41 controls the entire server device 40. The communication unit 42 is a communication unit for performing communication with the digital camera 10 a via the network 38. The recording unit 43 records position information transmitted from the digital camera 10a via the network 38. The calculation unit 44 calculates an average action area from the position information recorded and accumulated in the recording unit 43. The determination unit 45 compares and determines the average action area calculated by the calculation unit 44 and the current position of the digital camera 10a.

  Next, the operation of the communication system configured as shown in FIG. 12A will be described with reference to the flowchart of FIG.

  FIG. 13A is a flowchart for explaining the control operation of the digital camera 10a in FIG. 12A, and FIG. 13B is a flowchart for explaining the control operation of the server device 40 in FIG. 12A. is there.

  First, in step S51, the position information acquisition unit 15 of the digital camera 10a receives radio waves from the GPS at a certain time interval and acquires current position information. Here, the acquired current position information is transmitted to the server device 40 via the network 38 by the communication unit 19 in subsequent step S52.

  In the server apparatus 40, first, the position information transmitted from the digital camera 10a is received by the communication unit 42 in step S61. Next, in step S62, the information is recorded in the recording unit 43 based on the position information received in step S61.

  Next, in step S63, in the server device 40, the position information data recorded and accumulated in the recording unit 43 is read by the control unit 41, and the average action area of the user having the digital camera 10a is calculated. . The calculation of the action area may be a method similar to the method performed in step S2 of the flowchart of FIG. Alternatively, when a map information database is recorded in the recording unit 43 of the server device 40, an average action area is calculated based on the map information and a passable part such as a road. You may make it change the weighting of a threshold value.

  In step S64, the determination unit 45 of the server device 40 calculates the distance between the current position information and the average action area calculated in step S63. Next, in step S65, it is determined whether or not the distance between them is a predetermined distance or more. Here, if the determination unit 45 of the server device 40 determines that the distance is greater than the predetermined distance, the process proceeds to step S66, and if not, the step S66 is skipped.

  In step S66, it is estimated that the user who has the digital camera 10a is in a place where he / she does not usually visit. Accordingly, the server device 40 transmits a message indicating that it is away from the average action area by a predetermined distance or more to the digital camera 10 a via the communication unit 42 and the network 38.

  The server device 40 acquires area information such as a shooting spot near the current position based on the current position and date / time information of the digital camera 10a, and uses the acquired information as a message (part) to the digital camera 10a. You may send it.

  In the digital camera 10a, information from the server device 40 is received in step S53 corresponding to step S66. Then, in step S54, a message for prompting shooting and, if possible, area information such as a nearby spot is displayed on the display unit 14. For example, as shown in FIG. 12B, a message indicating that the place is a place where the user does not normally visit and nearby area information is displayed on the display unit 14 disposed on the back of the digital camera 10.

  In addition to displaying a message prompting shooting, a shooting mode and parameters suitable for shooting at the current location may be displayed and set based on position information and area information.

  Thereafter, in step S55, the digital camera 10a shifts to a standby state, and after a predetermined time elapses, shifts to step S51 again to acquire position information.
