  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The scope of the invention is not limited to the illustrated example.

  First, an imaging apparatus 1 as a positioning apparatus according to the present embodiment will be described with reference to FIG.

  The imaging apparatus 1 of the present embodiment is an apparatus that can store image data obtained by imaging in association with position information of an imaging point when an imaging operation is performed during movement.

  The imaging apparatus 1 according to the present embodiment performs positioning processing during movement and records position data at each point on the movement route. That is, as shown in FIG. 1, the imaging apparatus 1 includes a CPU (Central Processing Unit) 10 that performs overall control of the apparatus, and a RAM (Random) that provides a working memory space to the CPU 10. (Access Memory) 11, ROM (Read Only Memory) 12 storing a control program executed by the CPU 10 and control data, and GPS reception for receiving transmission data from a GPS (Global Positioning System) satellite The antenna 13 and the GPS receiving unit 14, the display unit 15 that displays various information and images, the power source 16 that supplies the operation voltage to each unit, and the movement history in which a series of position data along the movement path is accumulated Data storage unit 17, camera device 18 that performs imaging, map database 19 that stores nationwide map data and the like, and current time information are output That a clock unit 20, and a designated area storage unit 21, an operation unit 22 for inputting an operation command from outside.

  The CPU 10 as control means is a multi-core CPU including a main core 10a and a sub-core 10b. The main core 10a is activated when the camera device 18 is operated. The sub-core 10b operates as long as the operating voltage is supplied from the power supply 16, and mainly performs control of GPS positioning described later. In this embodiment, a multi-core CPU having two processors in one CPU 10 is used. However, the number of cores may be one, or three or more. Moreover, you may be comprised by several CPU.

  The GPS receiving unit 14 as positioning means performs demodulation processing on a signal received via the GPS receiving antenna 13 based on an operation command from the CPU 10 and sends various transmission data of GPS satellites to the CPU 10. The CPU 10 can acquire position data representing the current position by performing a predetermined positioning calculation based on the transmission data of the GPS satellite.

  The movement history data storage unit 17 is composed of, for example, a RAM or a nonvolatile memory, and records movement history data. In the movement history data, position data acquired while the apparatus is moving is sequentially registered.

  The camera device 18 as an imaging unit includes, for example, an imaging element such as a complementary metal oxide semiconductor (CMOS) sensor or a charge coupled device (CCD), a lens that forms an image of an object, and the like, and performs imaging according to a command from the CPU 10. This is an apparatus for converting an image of a subject imaged on an element into a digital signal and recording it. The camera device 18 is provided with, for example, a large-capacity storage device (recording medium) 18a, and image data (captured image information) obtained by imaging is stored in the storage device 18a. . That is, the storage device 18a constitutes storage means.

The map database 19 is constituted by a recording medium such as a ROM, for example, and stores map data for all over Japan.
The recording medium applied to the map database 19 in the present embodiment is not limited to the ROM, but stores a mass storage device such as an HDD (Hard Disk Drive), a CD-ROM, a DVD-RAM, or a memory card. The recording medium reader may be used.

  The designated area storage unit 21 is composed of, for example, a RAM or a nonvolatile memory, and stores information for specifying an area designated by the user as will be described later. The designation of the area can be performed, for example, by designating a plurality of points by the user. The information for specifying the designated area is, for example, information indicating latitude / longitude (latitude / longitude information).

  In the ROM 12, an initial setting program for setting conditions for position measurement (GPS positioning) using GPS, position data of each point on the moving route is acquired by GPS positioning, and the conditions for GPS positioning are varied. A positioning interval change control program, an imaging program for saving image data obtained by imaging of the camera device 18 in the storage device 18a, and the like are stored. In addition to being stored in the ROM 12, this program can be stored in a portable recording medium such as an optical disk, a non-volatile memory such as a flash memory, etc., which can be read by the CPU 10 via a data reader, for example. is there. In addition, a form in which such a program is downloaded to the imaging apparatus 1 via a communication line using a carrier wave as a medium can be applied.

  Next, an initial setting process executed in the imaging apparatus 1 configured as described above will be described with reference to FIG. This initial setting process is realized by the CPU 10 reading out an initial setting program stored in the ROM 12 and executing it. The initial setting process is executed when a predetermined initial setting operation is performed by the user via the operation unit 22. Note that when an initial setting operation is performed by the user, for example, an initial setting screen is displayed on the display unit 15, and various setting operations can be accepted.

  When the initial setting process is started, the CPU 10 determines whether or not to designate an arbitrary shape indicating the area range (step S101). Specifically, the CPU 10 determines, for example, whether the user has performed a setting operation for designating an arbitrary shape indicating the area range according to the initial setting screen displayed on the display unit 15. It is determined whether or not an arbitrary shape indicating a range is designated.

  When the CPU 10 determines that an arbitrary shape indicating the area range is designated (step S101: Y), the CPU 10 executes an area designation process (step S102). Specifically, the CPU 10 reads predetermined map data from the map database 19 and displays a map on the display unit 15. The CPU 10 displays a detailed map of the area desired by the user as shown in FIG. The CPU 10 receives input of a plurality of points from the map of the area displayed on the display unit 15 by operating the operation unit 22. For example, in the example illustrated in FIG. 5, input of “spot 1” to “spot 6” is accepted.

Subsequently, the CPU 10 performs registration so that the designated area can be specified from the information of each point that has received the input (step 103). Specifically, the CPU 10 specifies the latitude / longitude information of the point for which the input has been received with reference to the map data, and stores the latitude / longitude information for each point in the designated area storage in the manner shown in FIG. 6, for example. Store in the unit 21. Therefore, as shown in FIG. 5, the area surrounded by connecting these designated points can be specified as an arbitrary shape indicating the range of the designated area.
It should be noted that the number of points where input can be accepted is not limited to that described above, and any mode can be used as long as a region can be specified by designating a plurality of points. For example, by inputting two points, it is possible to specify a rectangular area having the two input points as diagonals as an arbitrary shape indicating the range of the designated area. Further, the greater the number of points to be input, the more the area can be specified as an arbitrary shape indicating the range of the designated area.
In the present embodiment, a detailed map of the area desired by the user is read from the map database 19 by operation, and the map is displayed on the display unit 15 to specify the area. An arbitrary shape indicating the area range may be designated based on the current location.

  On the other hand, when the CPU 10 does not determine in step S101 that an arbitrary shape indicating the range of the designated area is designated (step S101: N), the process of step S102 and step S103 is not performed, and step S104 is performed. Execute the process.

  In step S104, the CPU 10 determines whether or not to set a reception interval (step S104). Specifically, for example, the CPU 10 sets the positioning interval for GPS positioning when the user is within the designated area set as described above according to the initial setting screen displayed on the display unit 15. It is determined whether or not to set a reception interval depending on whether or not a setting operation has been performed.

  When it is determined that the reception interval is set (step S104: Y), the CPU 10 executes a reception interval setting process (step S105). Specifically, the CPU 10 reads a reception interval setting table stored in the ROM 12 and displays a set reception interval on the display unit 15. The settable reception intervals are shorter than the initially set reception interval of 10 minutes, for example, 1 minute, 3 minutes, 5 minutes, and 7 minutes. The reception interval may be longer than the initially set reception interval of 10 minutes, for example, 11 minutes, 13 minutes, 15 minutes, and 17 minutes.

  Subsequently, when any one of a plurality of settable reception intervals (for example, 1 minute, 3 minutes, 5 minutes, and 7 minutes) is selected by the operation of the operation unit 22, the CPU 10 receives the selected reception. The interval (for example, 1 minute) is set as a positioning interval for GPS positioning when it falls within the set designated area, and the information is stored in the RAM 11 (see FIG. 6) (step S106). The process ends.

  On the other hand, when it is determined in step S104 that the reception interval is not set (step S104: N), the CPU 10 ends the process without executing the processes of steps S105 and S106.

  Next, the positioning interval change control process performed after the initial setting process will be described with reference to FIG. This positioning interval change control process is realized by the CPU 10 reading a positioning interval change control program stored in the ROM 12 and executing it. This positioning interval change control process is executed when the operating voltage is supplied from the power supply 16 to the sub-core 10b.

  When the positioning interval change control process is started, the CPU 10 stops (SLEEP) the function of a device (GPS module) for performing GPS positioning such as the GPS receiver 14 (step S201).

  Next, the CPU 10 starts measurement after the GPS module is in the SLEEP state (step not shown), and determines whether or not the initially set T1 time has elapsed from the start time (step S202). . The T1 time is set to 10 minutes, for example, but may be another time. If the CPU 10 does not determine that the T1 time has elapsed (step S202: N), the CPU 10 repeatedly executes the process of step S202 until it is determined that the T1 time has elapsed. On the other hand, when determining that the time T1 has elapsed (step S202: Y), the CPU 10 activates the GPS module (step S203).

The CPU 10 measures the current position by GPS positioning, and stores the positioning result in the movement history data storage unit 17 (step S204). Specifically, the CPU 10 performs positioning by calculating the current position based on transmission data from a plurality of GPS satellites received by the GPS receiving unit 14, and uses the positioning result as movement history data. Store in the storage unit 17.
Yeah.

  CPU10 acquires the information on the designated area registered beforehand (step S205). That is, the CPU 10 reads the latitude / longitude information stored in the designated area storage unit 21 as described above, and acquires the designated area from the read latitude / longitude information. Here, if a plurality of designated areas are registered, the CPU 10 acquires all the designated areas.

  Based on the positioning result in step S204 and the information on the designated area acquired in step S205, the CPU 10 determines whether the current position is outside or inside an arbitrary shape indicating the range of the designated area (step S206). ). When the CPU 10 does not determine that the current position is within an arbitrary shape indicating the range of the designated area (step S206: N), the current position is the range of the designated area for all the designated areas acquired in step S205. It is determined whether or not a check has been made as to whether or not it is within an arbitrary shape (step S207). If the CPU 10 determines that all designated areas have been checked (step S207: Y), it executes the process of step S201. On the other hand, when the CPU 10 does not determine that all the designated areas have been checked (step S207: N), the CPU 10 proceeds to the process of step S205 and performs the same process for the other designated areas.

  Further, when the CPU 10 determines in step S206 that the current position is within an arbitrary shape indicating the range of the designated area (step S206: Y), the CPU 10 determines an arbitrary position indicating the range of the specified area. It is determined whether or not it is first determined that it is within the shape (step S208). When the CPU 10 first determines that the current position is within an arbitrary shape indicating the range of the designated area (step S208: Y), the CPU 10 determines an arbitrary shape indicating the range of the specified area. After starting the measurement of the elapsed time after first being determined to be within (step S209), the GPS module is set to the sleep state (step S209A). As a result, it is possible to grasp the approximate elapsed time after becoming an arbitrary shape indicating the range of the designated area. On the other hand, when the CPU 10 does not determine that the current position is initially determined to be within an arbitrary shape indicating the range of the designated area (step S208: N), the process of step S209A is not performed and step S209A is not performed. Execute the process.

  The CPU 10 determines whether or not T2 time which is the reception interval (for example, “1 minute” reception interval) selected in Step S105 and Step S106 has elapsed since the GPS positioning was performed in Step S203 (Step S203). S210). Here, T2 time is the reception interval (step S106) selected by the user as described above, and is the GPS positioning interval within the designated area stored in the RAM 11 (see FIG. 6). is there. When the CPU 10 does not determine that the T2 time has elapsed (step S210: N), the CPU 10 repeatedly executes the processes of steps S209A and S210 until it is determined that the T2 time has elapsed. On the other hand, when the CPU 10 determines that the time T2 has elapsed (step S210: Y), the CPU 10 proceeds to the process of step S203 and performs GPS positioning.

  Next, imaging processing will be described with reference to FIG. This imaging process is realized by reading out and executing an imaging program stored in the ROM 12 by the CPU 10.

  First, the CPU 10 acquires image data of an image captured by the camera device 18 (step S301).

  The CPU 10 measures the current position by GPS positioning as described above (step S302). Note that the positioning result obtained by the previous GPS positioning may be read from the movement history data storage unit 17.

  The CPU 10 determines whether or not the current position acquired in step S302 is within the designated area set as described above (step S303). When the CPU 10 determines that the current position is within the range of the designated area (step S303: Y), the CPU 10 acquires the measurement result of the elapsed time when the measurement was started as described above (step S304). Thereafter, the CPU 10 calculates the difference between the elapsed time acquired last time and the elapsed time acquired this time, thereby acquiring the elapsed time from when the previous image was captured (step S305).

  On the other hand, when the CPU 10 does not determine in step S303 that the current position is within the designated area (step S303: N), the process of step S306 is performed without executing the processes of step S304 and step S305. Run.

  In step S306, the CPU 10 associates the image data acquired in step S301 with the measurement result of the elapsed time acquired in step S304 and the elapsed time from the previous image acquisition acquired in step S305. It memorize | stores in the memory | storage device 18a of the apparatus 18 (step S306), and complete | finishes this process. At this time, the current time may be acquired from the clock unit 20 and associated with the image data.

  In the present embodiment, by being configured as described above, GPS positioning is performed as described below, and image data is stored.

  That is, as shown in FIG. 5, the designated area A is specified by inputting “spot 1” to “spot 6” as described above. Thereafter, before the user who owns the imaging device 1 falls within the range of the designated area A, GPS positioning is performed every T1 hours. Then, when it is determined that the GPS positioning is within the range of the designated area A, the subsequent GPS positioning interval is T2 time set in advance by the user. At this time, the measurement of the elapsed time from the range of the designated area A is started.

  Thereafter, when the user performs imaging at the point P using the camera device 18, the position data obtained by GPS positioning and the elapsed time are acquired together with the image data. The position data and the elapsed time are stored in the storage device 18a in association with the image data. For example, when an image based on the image data obtained by imaging at this point P is displayed on the display unit 15, as shown in FIG. 7, together with the captured image I 1, the captured date / time information D and position data The position information S and the elapsed time T based on are displayed. Here, the time displayed in the upper part of the elapsed time T indicates the elapsed time since the time is within the range of the designated area A. In addition, the time displayed in the lower part of the elapsed time T indicates the elapsed time from when the previous image was captured. Below the position information S, for example, when the imaged position is around the scenic spot, the scenic spot information U indicating that it is around the scenic spot is displayed. The scenic spot can be specified by referring to the map database 19, for example. In the example shown in FIG. 7, since there is no scenic spot in the vicinity, the scenic spot information U is not displayed.

  Thereafter, when the user performs imaging at the point Q using the camera device 18, the position data obtained by GPS positioning and the elapsed time are acquired together with the image data. For example, when an image based on image data obtained by imaging at this point Q is displayed on the display unit 15, as shown in FIG. 8, together with the captured image I 2, the captured date / time information D and position information S and elapsed time T are displayed. In the example shown in FIG. 8, the elapsed time T is shown in the upper stage as the elapsed time since it was within the range of the designated area A, and the elapsed time since the last imaging at the point P is in the lower stage. It is shown. Further, as a result of referring to the map database 19, it is determined that the point Q is in the vicinity of “Mibu-ji”, so “Surbu-ji Temple” is displayed in the scenic spot information U.

  After that, when the user who owns the imaging device 1 is out of the designated area A and performs GPS positioning, if it is determined that the user is not within the designated area A, the interval between subsequent GPS positionings is T1. It will be time.

  As described above, in the present embodiment, the GPS receiving unit 14 performs position information positioning every time a predetermined positioning condition is satisfied. The CPU 10 designates an arbitrary shape indicating the area range. The CPU 10 determines whether or not the current position indicated by the position information measured by the GPS receiving unit 14 belongs to or outside an arbitrary shape indicating the range of the designated area. The CPU 10 changes the positioning condition of the GPS receiving unit 14 based on the determination result. As a result, the user specifies an arbitrary range and the GPS positioning conditions are changed when the range is within or outside the range, so the power consumption can be reduced by changing the positioning conditions for GPS positioning, The position accuracy in the area desired by the user can be improved, and the user's needs can be met.

  In the present embodiment, the GPS receiver 14 measures the position information at a predetermined time interval. The CPU 10 changes the time interval for positioning by the GPS receiver 14 based on the determination result of whether or not it belongs outside or inside the designated range shape, and belongs to outside or inside the designated range shape. The time interval for positioning by the GPS receiver 14 when determined is set. As a result, since the positioning interval of GPS positioning in the specified range can be set, it is possible to acquire the movement history at an arbitrary interval, and the convenience for the user can be improved.

  In the present embodiment, the camera device 18 captures the subject and acquires captured image information. The storage device 18a stores captured image information captured by the camera device 18. As a result, the user can specify in advance the area where imaging is desired, and the positional information can be accurately recorded together with the captured image information, so that convenience is improved.

  Further, in the present embodiment, the CPU 10 measures the elapsed time since it was first determined that it belongs to or outside the shape of the specified range, and belongs to the outside or inside of the shape of the specified range. When the captured image information is acquired by the camera device 18 when it is determined, the captured image information is stored in the storage device 18a in association with the elapsed time measured when the captured image information is acquired. As a result, the passage of time in the designated range designated by the user can be managed together with the captured image information, and convenience is improved.

In the present embodiment, the imaging apparatus includes the positioning device according to the present embodiment. However, according to the present embodiment, a general portable navigation device or a positioning device installed on a moving body is used. A positioning device may be applied.
Further, the time interval for positioning is changed based on the determination result as to whether it belongs to or outside the shape of the specified range. This time interval for positioning is initially set, for example, 10 minutes. The time interval is shorter than the time interval, such as 1 minute or 3 minutes. However, a time interval such as 15 minutes or 17 minutes longer than the initially set time interval of 10 minutes may be used.

  In this embodiment, the GPS positioning interval is changed by setting the GPS module to the SLEEP state. However, the position data acquisition timing may be changed without setting the SLEEP state.

  In the present embodiment, the position data is acquired at predetermined intervals by GPS positioning. However, for example, a 3-axis geomagnetic sensor, a 3-axis acceleration sensor, and the like are provided, and during the period when GPS positioning is not performed, You may make it perform the positioning by autonomous navigation based on a measurement result.

  In this embodiment, the positioning conditions for GPS positioning are changed when belonging to the specified area. However, when the positioning conditions for GPS positioning are changed, the positioning conditions are changed by the user. It may be possible to select whether or not to do.

  In the present embodiment, the positioning unit is configured to perform positioning using GPS. However, for example, a configuration in which positioning is performed by communication with a mobile phone base station, RFID (Radio Frequency IDentification), or the like is used. Various other configurations can be applied, such as a configuration in which the current position is determined by receiving or inputting position information from the outside.
