Description

  The present invention relates to a photographing apparatus, a portable communication device, and a warning system that can prevent leaving unattended due to misplacement or the like.

  2. Description of the Related Art In recent years, mobile communication devices such as a camera and a mobile phone having a camera shake correction function at the time of photographing and a positioning function based on a GPS (Global Positioning System) signal have been provided.

  There is also known a technique for warning the state of leaving the portable communication device due to misplacement after self-timer photography.

That is, the zoom lens 12z is driven by the zoom motor 60z to move back and forth on the photographing optical axis 120, thereby changing the focal length. The focus lens 12f is driven by the focus motor 60f to move back and forth on the photographing optical axis 120, thereby changing the imaging position. In addition, the aperture 12i is driven by the iris motor 60i, so that the opening amount changes stepwise, thereby changing the aperture value. The CPU 42 controls the driving of the zoom motor 60z, the focus motor 60f, and the iris motor 60i via the zoom motor driver 62z, the focus motor driver 62f, and the iris motor driver 62i, whereby the zoom lens 12z, the focus lens 12f, and the aperture 12i are controlled.

  When a through image is displayed on the image display unit 30, images are continuously captured by the image sensor 14, and the obtained image signals are continuously processed to generate a YUV signal. The generated YUV signal is applied to the encoder 28 via the RAM 46, converted into a signal format for display, and output to the image display unit 30. As a result, a through image is displayed on the image display unit 30.

  When an image is recorded, an image is picked up by the image pickup device 14 in accordance with a shooting command from the operation unit 50, and the obtained image signal is processed to generate a YUV signal. The generated YUV signal is added to the compression / decompression processing unit 32, converted into predetermined compressed image data (for example, JPEG), and then stored in the storage medium 36 via the media controller 34.

[First Embodiment]
In the first embodiment, the CPU 42 of the camera 10 in FIG. 1 performs self-timer shooting using the timer 76 of the camera 10, and then again sets the timer time of the camera 10 to the same time as that of the self-timer shooting. At the same time, the alarm is started by the speaker 64 and the light source 68 of the camera 10, and the alarm by the speaker 64 and the light source 68 is continued during the time measurement period. Stop.

  FIG. 3 is a flowchart showing an exemplary flow of control processing of the camera 10 in the first embodiment. This control process is performed by the CPU 42 of the camera 10.

  In FIG. 3, when a self-timer photographing instruction is input to the operation unit 50 of the camera 10, self-timer photographing is performed using the timer 76 of the camera 10 (step S102).

  The self-timer can be measured by using the operation unit 50 and the image display unit 30 of the camera 10 to select a desired time from a plurality of time-measure candidates (for example, 5 seconds, 10 seconds, and 20 seconds). Can be selected and entered. It is also possible to input an arbitrary time (for example, 30 seconds). The inputted time measurement is stored (set) in the EEPROM 48 of the camera 10. When the timekeeping time is not input, the default timekeeping time (for example, 10 seconds) stored in advance in the EEPROM 48 is used.

  In the self-timer shooting, when a shutter operation is performed by the operation unit 50 of the camera 10, the time is set by the timer 76 of the camera 10 for the time set in the EEPROM 48 of the camera 10 and then shooting is performed. That is, the subject is imaged by the imaging element 14 of the camera 10, and the captured image obtained by the imaging is stored in the storage medium 36.

  At the end of self-timer shooting, first, the notification function switching instruction stored in the EEPROM 48 of the camera 10 is referred to determine whether or not the notification function is on (step S104). When the notification function is on In step S106, sound output from the speaker 64 of the camera 10 and light emission from the light source 68 are started (step S106), and the time (for example, 10 seconds) used for self-timer shooting is set in the timer 76 used for self-timer shooting. The timer 76 is started again (step S108). Then, it is determined whether or not the timer 76 is within the timed time (step S110). If it is within the timed time of the timer 76, sound output and light emission are continued while the timed time of the timer 76 has elapsed. The sound output and the light emission are stopped (step S112).

  If the notification function is off in step S104, the process ends without performing sound output and light emission.

  The notification function switching instruction indicating the on / off of the notification function can be input by a switch of the operation unit 50 of the camera 10 or a GUI (Graphic User Interface). The notification function switching instruction may be input to the camera 10 by wireless communication by inputting the notification function switching instruction using the operation unit 250 of the mobile phone 200 of FIG. The notification function switching instruction received by the camera 10 is stored (set) in the EEPROM 48 of the camera 10.

  In the present embodiment, sound output and light emission for preventing misplacement are simultaneously performed for the same time as the time measured for self-timer photographing. That is, the time taken for the self-timer photographing is stored in the EEPROM 48 of the camera 10 as the time necessary and sufficient for the movement between the place where the camera 10 is installed and the place where the user is photographed. By performing the above, a warning is given only for a time necessary and sufficient for the user to collect the camera 10, and no sound output or light emission is performed any further. Therefore, it is possible to achieve both the prevention of misplacement without fail and the prevention of inconvenience to those around.

  Also, when shooting with a self-timer in a noisy place or when using a person with hearing impairment, there is a concern that the warning sound alone may not be noticed. In this embodiment, light emission is performed simultaneously with sound output. Therefore, it can be surely prevented from being misplaced.

  Further, since the timer 76, the speaker 64, and the light source 68 originally mounted on the camera 10 are used, the effect of preventing misplacement can be exhibited without increasing the cost of hardware.

[Second Embodiment]
In the second embodiment, the CPU 42 of the camera 10 in FIG. 1 detects the presence or absence of movement of the camera 10 by the camera shake detection sensor 74 of the camera 10 after performing self-timer shooting using the timer 76 of the camera 10. Using the timer 76 of the camera 10, the still time of the camera 10 is counted, and when the stationary time exceeds a certain time, it is determined that the camera 10 has been left behind and a warning is issued by the speaker 64 and the light source 68 of the camera 10.

  FIG. 4 is a flowchart illustrating an exemplary flow of control processing of the camera 10 according to the second embodiment. This control process is performed by the CPU 42 of the camera 10.

  In FIG. 4, when a self-timer photographing instruction is input to the operation unit 50 of the camera 10, self-timer photographing is performed using the timer 76 of the camera 10 (step S202). In the self-timer photographing, as already described in the first embodiment, photographing is performed after time keeping is performed for the time measured (stored) in the EEPROM 48 of the camera 10.

  At the end of self-timer shooting, first, the notification function switching instruction stored in the EEPROM 48 of the camera 10 is referred to determine whether or not the notification function is on (step S204). When the notification function is on The timer used for self-timer shooting is set to the timer 76 used for self-timer shooting, and the timer 76 is started again (step S206).

  If the camera shake detection sensor 74 of the camera 10 detects the presence or absence of movement of the camera 10 (step S208), and if it is determined that there is no movement in the movement presence / absence determination (step S210), whether or not the timer 76 is within the measured time. (Step S212), and if it is within the time measured by the timer 76, the monitoring of the presence or absence of movement of the camera 10 (step S208) is continued, while the time measured by the timer 76 has elapsed (that is, the stationary time has elapsed). When the time of the self-timer photographing as the threshold is exceeded, it is determined that the camera 10 is left behind, and the sound output from the speaker 64 of the camera 10 and the light emission from the light source 68 are performed simultaneously (step S214).

  If it is determined in step S210 that the camera 10 has moved within the timed period, it is determined that the camera 10 has not been left behind, and the process ends without performing sound output and light emission. In step S204, even when the notification function is off, the sound output and light emission are not performed, and the process ends.

  The notification function switching instruction indicating whether the notification function is on or off can be input by a switch of the operation unit 50 of the camera 10 or a GUI. The notification function switching instruction may be input to the camera 10 by wireless communication by inputting the notification function switching instruction using the operation unit 250 of the mobile phone 200 of FIG. The notification function switching instruction received by the camera 10 is stored (set) in the EEPROM 48 of the camera 10.

  In the present embodiment, misplacement detection is performed based on whether or not the stationary time is longer than the time measured for self-timer imaging. That is, the time taken for the self-timer photographing is stored in the EEPROM 48 of the camera 10 as the time necessary and sufficient for the movement between the place where the camera 10 is installed and the place where the user is photographed. It is possible to detect misplacement accurately.

  In addition, when a warning is issued, light is emitted at the same time as sound output, so even if you take a self-timer shot in a noisy place or if you are using a hearing-impaired person, make sure to prevent misplacement. can do.

  In addition, although the case where the presence or absence of the movement of the camera 10 is detected using the camera shake detection sensor 74 has been described as an example, the present invention is not particularly limited to such a case, and the camera 10 performing positioning based on the GPS signal. Then, the presence or absence of movement of the camera 10 may be detected based on the position information calculated by the positioning unit 72 of the camera 10.

  In the present embodiment, a camera 64 detection sensor 74 (or positioning unit 72) and a timer 76 that are originally mounted on the camera 10 are used to detect whether the camera 10 is left unattended, and the speaker 64 and the light source that are originally mounted on the camera 10. Since the alarm is issued using 68, the misplacement prevention effect can be exhibited without increasing the hardware cost.

[Third Embodiment]
In the third embodiment, the CPU 42 of the camera 10 in FIG. 1 detects the presence or absence of movement of the camera 10 by the camera shake detection sensor 74 of the camera 10 after performing self-timer shooting using the timer 76 of the camera 10. A timer 76 of the camera 10 is used to measure the stationary time of the camera 10, and when the stationary time exceeds a certain time, the wireless communication unit 70 of the camera 10 makes a wireless notification to the mobile phone 200 of FIG.

It is a flowchart to show. The control process of FIG. 5A is performed by the CPU 42 of the camera 10, and the control process of FIG. 5B is performed by the CPU 242 of the mobile phone 200.

  In FIG. 5A, when a self-timer shooting instruction is input to the operation unit 50 of the camera 10, self-timer shooting is performed using the timer 76 of the camera 10 (step S302). In the self-timer photographing, as already described in the first embodiment, photographing is performed after time keeping is performed for the time measured (stored) in the EEPROM 48 of the camera 10.

  At the end of the self-timer shooting, first, the notification function switching instruction of the EEPROM 48 of the camera 10 is referred to determine whether or not the notification function is on (step S304). The time measured for the timer shooting is set in the timer 76 used for the self-timer shooting, and the timer 76 is started again (step S306).

  If the camera shake detection sensor 74 of the camera 10 detects the presence or absence of movement of the camera 10 (step S308) and it is determined that there is no movement in the movement presence / absence determination (step S310), whether or not the timer 76 is within the measured time. (Step S312), and if it is within the time measured by the timer 76, the monitoring of the presence or absence of movement of the camera 10 (step S308) is continued, while the time measured by the timer 76 has elapsed (that is, the stationary time has elapsed). When the time measured by the self-timer photographing as a threshold is exceeded, it is determined that the camera 10 has been left behind, and the wireless communication unit 270 of the camera 10 notifies the specific mobile phone 200 by, for example, long-distance wireless communication (step S314). ). Note that the mobile phone 200 and the camera 10 are registered in advance by short-range wireless communication or the like, and the camera 10 makes a report only to the owner's mobile phone 200.

  If it is determined in step S310 that the camera 10 has moved within the timed period, it is determined that the camera 10 has not been left behind, and the process ends without reporting to the mobile phone 200. In step S304, even when the notification function is off, the process is terminated without reporting to the mobile phone 200.

  As shown in FIG. 5B, the mobile phone 200 that has received the report from the camera 10 outputs sound from the speaker 264 of the mobile phone 200, generation of vibration by the vibrator 266 of the mobile phone 200, and Light emission by the light source 268 is simultaneously performed (step S332).

  The notification function switching instruction indicating whether the notification function is on or off can be input by a switch of the operation unit 50 of the camera 10 or a GUI. The notification function switching instruction may be input to the camera 10 by wireless communication by inputting the notification function switching instruction using the operation unit 250 of the mobile phone 200 of FIG. The notification function switching instruction received by the camera 10 is stored (set) in the EEPROM 48 of the camera 10.

  In the present embodiment, misplacement detection is performed based on whether or not the stationary time is longer than the time measured for self-timer imaging. That is, the time taken for the self-timer photographing is stored in the EEPROM 48 of the camera 10 as the time necessary and sufficient for the movement between the place where the camera 10 is installed and the place where the user is photographed. It is possible to detect misplacement accurately.

  In addition, when a warning is issued, vibration is generated and light is emitted at the same time as sound output, so even if self-timer shooting is performed in a noisy place or a person with hearing impairment is used It can prevent misplacement.

  In addition, although the case where the presence or absence of the movement of the camera 10 is detected using the camera shake detection sensor 74 has been described as an example, the present invention is not particularly limited to such a case, and the camera 10 performing positioning based on the GPS signal. Then, the presence or absence of movement of the camera 10 may be detected based on the position information calculated by the positioning unit 72 of the camera 10.

  In the present embodiment, the camera 10 detection sensor 74 (or the positioning unit 72) and the timer 76 that are originally mounted on the camera 10 are used to detect whether the camera 10 is left unattended, and the speaker 264 that is originally mounted on the mobile phone 200. Since the alarm is issued using the vibrator 266 and the light source 268, the misplacement prevention effect can be exhibited without increasing the hardware cost.

[Fourth Embodiment]
In the fourth embodiment, the CPU 42 of the camera 10 in FIG. 1 transmits a report indicating the self-timer photographing timing to the mobile phone 200 in FIG. 2 by the wireless communication unit 70 of the camera 10 by wireless communication. The CPU 242 of the mobile phone 200 receives the notification indicating the time of the self-timer shooting transmitted from the camera 10 by the wireless communication unit 270 of the mobile phone 200, and the position information at the time of self-timer shooting obtained by the positioning unit 272 of the mobile phone 200 And the current position information, the distance between the position at the time of self-timer shooting and the current position is calculated, and when the calculated distance becomes larger than the threshold, the speaker 264 and the vibrator of the mobile phone 200 266 and light source 268 alerts.

  FIG. 6A is a flowchart showing an exemplary flow of control processing on the camera 10 side in the fourth embodiment, and FIG. 6B shows an exemplary flow of control processing of the mobile phone 200 in the fourth embodiment. It is a flowchart to show. The control process of FIG. 6A is performed by the CPU 42 of the camera 10, and the control process of FIG. 6B is performed by the CPU 242 of the mobile phone 200.

  6A, when a self-timer shooting instruction is input to the operation unit 50 of the camera 10, whether or not the notification function is turned on with reference to the notification function switching instruction stored in the EEPROM 48 of the camera 10. If the notification function is on, the wireless communication unit 70 of the camera 10 notifies the specific mobile phone 200 of the self-timer photographing time by short-range wireless communication (step S404). Note that the mobile phone 200 and the camera 10 are registered in advance by short-range wireless communication or the like, and the camera 10 reports only to the specific mobile phone 200 of the owner.

  After such notification to the mobile phone 200, the camera 10 performs self-timer shooting (step S406).

  On the other hand, the mobile phone 200 that has received the notification of the self-timer shooting timing from the camera 10, in FIG. 6B, uses the self-timer to obtain the position information calculated based on the GPS signal by the positioning unit 272 of the mobile phone 200. Obtained as position information (shooting position information) of the camera 10 at the time of shooting (step S432). Next, a threshold for distance determination is read from the EEPROM 248 of the mobile phone 200 (step S434), waits for a certain period of time (step S436), and the mobile phone 200 calculated by the positioning unit 272 of the mobile phone 200 based on the GPS signal. Is acquired as the current position information of the mobile phone 200 (step S438), the shooting position information (position information acquired in step S432) and the current position information of the mobile phone 200 (position information acquired in step S438). ), The distance between the shooting position and the current position of the mobile phone 200 is calculated (step S440), and it is determined whether or not the calculated distance is larger than a threshold for distance determination (step S442). If it is larger than the threshold value (that is, when it is determined as a long distance), the speaker 264 of the mobile phone 200 Performing sound output, and the light emission by the vibration generator and the light source 268 by the vibrator 266 simultaneously (step S444).

  Note that the notification of the self-timer shooting timing from the camera 10 to the mobile phone 200 (step S404) is not particularly limited when using a short-distance wireless communication function such as Bluetooth, and the long-distance wireless communication function may be used. In addition, although the preferred case where the notification from the camera 10 to the mobile phone 200 is performed at the start of timing of self-timer shooting has been described, the present invention is not particularly limited to such a case. It may be performed later.

  In addition, by switching on / off of the notification function and changing the threshold for distance determination, wireless communication within a range in which the owner moves the camera 10 intentionally (for example, in the company premises), Unnecessary operations of the camera 10 and the mobile phone 200 such as positioning and warning can be eliminated.

  The notification function switching instruction indicating whether the notification function is on or off may be input using the operation unit 50 (switch, GUI interface, etc.) of the camera 10, or the operation unit 50 (GUI interface, etc.) of the mobile phone 200. May be used. When a notification function switching instruction is input from the mobile phone 200, the mobile phone 200 transmits a notification function switching instruction to the camera 10 by wireless communication. The notification function switching instruction received by the camera 10 is stored (set) in the EEPROM 48 of the camera 10. When the notification function switching instruction indicates that the notification function is off, the camera 10 does not transmit a notification of the self-timer photographing time, thereby preventing the mobile phone 200 from issuing a warning.

  The change of the threshold for determining the distance is input using the operation unit 250 (such as a GUI interface) of the mobile phone 200. The threshold for determining the distance is stored in the EEPROM 248 of the mobile phone 200.

  In the above, a simple case in which distance determination is performed using only position information measured on the mobile phone 200 side in the distance calculation (step S440) by the mobile phone 200 has been described as an example. A warning will also be given when you hold without forgetting. Therefore, in the distance determination step (S442), when the calculated distance exceeds the threshold value, the mobile phone 200 makes an inquiry to the camera 10 by short-range wireless communication, and the camera 10 responds to the inquiry. The warning (step S444) may be performed only when there is no response by short-range wireless communication, and the warning may not be performed when there is a response. That is, a range in which near field communication is possible in response to an inquiry from the wireless communication unit 270 of the mobile phone 200 by attempting near field communication by the wireless communication unit 70 of the camera 10 and the wireless communication unit 270 of the mobile phone 200. If the wireless communication unit 270 of the mobile phone 200 receives the response, the wireless communication unit 270 of the mobile phone 200 determines that the response is a short distance and a warning is issued. Not performed.

  In this embodiment, since the mobile phone 200 that the owner always wears can recognize that the camera 10 is away from the owner, it can be reliably prevented from being misplaced.

  In the present embodiment, the distance is calculated using position information measured based on the GPS signal and the necessity of the warning is determined. Therefore, the necessity of the warning is determined based on the presence / absence of the radio wave. Compared to the case where the necessity of warning is determined based on the radio field strength, the distance is accurately calculated regardless of the radio wave environment, and the necessity of warning is accurately determined. it can.

  Further, in the present embodiment, since the notification function is configured to be turned off (cancelled), when the camera 10 is intentionally placed instead of being misplaced, there is no inconvenience caused by a warning around. And receive notifications only when necessary. In addition, since the notification function is turned on and off not only from the camera 10 but also from the mobile phone 200 that is always carried, the annoyance is reduced.

  In the present embodiment, the distance determination threshold value can be changed, so that the range in which the owner moves while the camera 10 is intentionally placed (for example, within the company premises) By changing the threshold value, it is possible to prevent the camera 10 and the mobile phone 200 from operating when notification is not required.

  In the present embodiment, the left state of the camera 10 is detected using the positioning function (or wireless communication function) originally installed in the mobile phone 200, and the speaker 264 and the vibrator originally installed in the mobile phone 200 are detected. Since the alarm is issued using the H.266 and the light source 268, the misplacement prevention effect can be exhibited without increasing the hardware cost.

  In the present embodiment, the camera 10 does not need a positioning function. Further, a long-distance wireless communication function is not essential, and a short-distance wireless communication function such as Bluetooth originally installed in the camera 10 for image transfer or the like can be used. Periodic communication between both the camera 10 and the mobile phone 200 is not necessary, and an increase in power consumption can be avoided.

[Fifth Embodiment]
In the fifth embodiment, the CPU 242 of the mobile phone 200 of FIG. 2 receives the position information of the camera 10 transmitted from the camera 10 of FIG. 1 by the wireless communication unit 270 of the mobile phone 200, and the position information of the camera 10 Based on the position information of the mobile phone 200 obtained by the positioning unit 272 of the mobile phone 200, the distance between the camera 10 and the mobile phone 200 is calculated. When the calculated distance is larger than the threshold, the camera 10 Is determined to be left behind, and a warning is issued by the speaker 264, vibrator 266, and light source 268 of the mobile phone 200.

In step S502, if the notification function is off, position information acquisition (step S504) and position information transmission (step S506) are not performed. The mobile phone 200 and the camera 10 are registered in advance by short-range wireless communication or the like, and the position information is transmitted from the camera 10 only to the owner's mobile phone 200.

  In FIG. 7B, the mobile phone 200 that has received the position information from the camera 10 reads the distance determination threshold value from the EEPROM 248 of the mobile phone 200 (step S532), and converts the GPS signal into the GPS signal by the positioning unit 272 of the mobile phone 200. The position information of the mobile phone 200 calculated based on the information is acquired (step S534), and the distance between the camera 10 and the mobile phone 200 is calculated based on the position information of the camera 10 and the position information of the mobile phone 200 ( In step S536), it is determined whether or not the calculated distance is greater than a threshold for distance determination (step S538). If the calculated distance is greater than the threshold (that is, determined to be a long distance), the speaker 264 of the mobile phone 200 is determined. Sound generation by the vibrator, vibration generation by the vibrator 266 and light emission by the light source 268 are performed simultaneously (steps). Flop S540).

  The transmission of position information from the camera 10 to the mobile phone 200 (step S506) may be performed using a short-range wireless communication function such as Bluetooth instead of the long-range wireless communication function. When the short-range wireless communication function is used, it is determined as a long distance even when the position information transmitted from the wireless communication unit 70 of the camera 10 is not received by the wireless communication unit 270 of the mobile phone 200 for a predetermined time or longer. (That is, Yes is determined in step S538), and an alarm (step S540) is performed.

  In addition, by switching the notification function on / off and changing the threshold for distance determination, positioning and wireless communication within the range where the owner moves with the camera 10 intentionally placed (for example, in the company premises) It is possible to eliminate useless operations of the camera 10 and the mobile phone 200 such as warnings.

  The notification function switching instruction indicating whether the notification function is on or off may be input using the operation unit 50 (switch, GUI interface, etc.) of the camera 10, or the operation unit 50 (GUI interface, etc.) of the mobile phone 200. May be used. When a notification function switching instruction is input from the mobile phone 200, the mobile phone 200 transmits a notification function switching instruction to the camera 10 by wireless communication. The notification function switching instruction received by the camera 10 is stored (set) in the EEPROM 48 of the camera 10. When the notification function switching instruction indicates that the notification function is off, the camera 10 does not transmit the position information, so that the mobile phone 200 does not issue a warning.

  The change of the threshold for determining the distance is input using the operation unit 250 (such as a GUI interface) of the mobile phone 200. The threshold for determining the distance is stored in the EEPROM 248 of the mobile phone 200.

  In the present embodiment, since the distance is calculated using the position information measured based on the GPS signal and the necessity of the warning is determined, the necessity of the warning can be accurately determined.

  In the present embodiment, the camera 10 and the mobile phone 200 are originally installed in the camera 10 and the mobile phone 200 to detect the state of leaving the camera 10 and the wireless communication function, and the mobile phone 200 is originally installed in the speaker 264 and the vibrator. Since the alarm is issued using the H.266 and the light source 268, the misplacement prevention effect can be exhibited without increasing the hardware cost.

[Sixth Embodiment]
In the sixth embodiment, the CPU 42 of the camera 10 of FIG. 1 receives the position information of the mobile phone 200 transmitted from the mobile phone 200 of FIG. 2 by the wireless communication unit 70 of the camera 10 and the position information of the mobile phone 200. And the position information of the camera 10 obtained by the positioning unit 72 of the camera 10, the distance between the camera 10 and the mobile phone 200 is calculated, and when the calculated distance is larger than the threshold, It is determined that the camera has been left behind, and the mobile phone 200 is notified of the position information of the camera 10.

  FIG. 8A is a flowchart showing a flow of an example of control processing on the mobile phone 200 side in the sixth embodiment, and FIG. 8B is a flow of an example of control processing on the camera 10 side in the sixth embodiment. It is a flowchart which shows. The control process in FIG. 8A is performed by the CPU 242 of the mobile phone 200, and the control process in FIG. 8B is performed by the CPU 42 of the camera 10.

  In FIG. 8A, it is determined whether or not the notification function is turned on with reference to the notification function switching instruction in the EEPROM 248 of the mobile phone 200 (step S632). The position information of the mobile phone 200 calculated based on the GPS signal by the positioning unit 272 of the 200 is acquired (step S634), and the position information is acquired by the wireless communication unit 270 of the mobile phone 200 by the long-distance wireless communication. (Step S636), wait for a fixed period of time (step S328), and repeat steps S632 to S638. In step S632, when the notification function is off, position information acquisition (step S634) and position information transmission (step S636) are not performed. Note that the mobile phone 200 and the camera 10 are registered in advance by short-range wireless communication or the like, and position information is transmitted from the mobile phone 200 only to the camera 10 of the owner.

  In FIG. 8B, the camera 10 that has received the position information from the mobile phone 200 reads the threshold for determining the distance from the EEPROM 48 of the camera 10 (step S602), and the positioning unit 72 of the camera 10 based on the GPS signal. The calculated position information of the camera 10 is acquired (step S604), and the distance between the camera 10 and the mobile phone 200 is calculated based on the position information of the camera 10 and the position information of the mobile phone 200 (step S606). Then, it is determined whether or not the calculated distance is greater than a distance determination threshold value (step S608). If the calculated distance is greater than the threshold value (that is, determined to be a long distance), the camera 10 to the mobile phone 200 is determined. The position information of the camera 10 is transmitted by long-distance wireless communication (step S610). Such transmission (report) of position information may be performed by e-mail. Waiting for a certain period of time (step S612), steps S602 to S612 are repeated. That is, when it is determined that the distance is long, the position information of the camera 10 is transmitted to the mobile phone at regular intervals. Note that the mobile phone 200 and the camera 10 are registered in advance by short-distance wireless communication or the like, and the camera 10 reports position information only to the owner's mobile phone 200.

  The mobile phone 200 that has received the report of the position information from the camera 10 generates sound output from the speaker 264 of the mobile phone 200 and generation of vibration by the vibrator 266 of the mobile phone 200, as shown in step S332 of FIG. At the same time, the light source 268 of the mobile phone 200 emits light.

  Transmission of position information from the mobile phone 200 to the camera 10 (step S636) may be performed using a short-range wireless communication function such as Bluetooth instead of the long-range wireless communication function. When the short-range wireless communication function is used, it is determined as a long distance even when the position information transmitted from the wireless communication unit 270 of the mobile phone 200 is not received by the wireless communication unit 70 of the camera 10 for a predetermined time or longer. (In other words, it is determined Yes in step S608), and position information transmission from the camera 10 to the mobile phone 200 is performed (step S610).

  In addition, by switching the notification function on / off and changing the threshold for distance determination, positioning and wireless communication within the range where the owner moves with the camera 10 intentionally placed (for example, in the company premises) It is possible to eliminate useless operations of the camera 10 and the mobile phone 200 such as warnings.

  The notification function switching instruction indicating whether the notification function is on or off is input using the operation unit 50 (GUI interface or the like) of the mobile phone 200. The notification function switching instruction is stored in the EEPROM 248 of the mobile phone 200. When the notification function switching instruction indicates that the notification function is off, the mobile phone 200 does not transmit the location information of the mobile phone 200, and thus the camera 10 reports the location information of the camera 10 (step S610). It will not be.

  The change of the threshold for distance determination may be input using the operation unit 50 (switch, GUI interface, etc.) of the camera 10 or input using the operation unit 250 (GUI interface, etc.) of the mobile phone 200. May be. When an instruction is input from the mobile phone 200, the distance determination threshold is transferred from the mobile phone 200 to the camera 10 by wireless communication. The threshold for determining the distance is stored in the EEPROM 48 of the camera 10.

  In the present embodiment, since the distance is calculated using the position information measured based on the GPS signal and the necessity of the warning is determined, the necessity of the warning can be accurately determined.

  In the present embodiment, the camera 10 and the mobile phone 200 are originally installed in the camera 10 and the mobile phone 200 to detect the state of leaving the camera 10 and the wireless communication function, and the mobile phone 200 is originally installed in the speaker 264 and the vibrator. Since the alarm is issued using the H.266 and the light source 268, the misplacement prevention effect can be exhibited without increasing the hardware cost.

[Seventh Embodiment]
In the seventh embodiment, the wireless communication unit 70 of the camera 10 in FIG. 1 transmits a specific radio wave having a specific frequency at a constant cycle time, and the wireless communication unit 270 of the mobile phone 200 in FIG. The presence / absence of a specific radio wave transmitted from the communication unit 70 and the radio wave intensity of the specific radio wave are detected. Also, the CPU 242 of the mobile phone 200 determines whether the camera 10 and the mobile phone 200 are connected to each other based on the presence / absence of the specific radio wave detected by the wireless communication unit 270 of the mobile phone 200 and whether the radio wave intensity of the specific radio wave exceeds a threshold value. If the distance between the camera 10 and the mobile phone 200 is determined to be long, a warning is issued by the speaker 264, the vibrator 266, and the light source 268 of the mobile phone 200. Here, the threshold for distance determination can be changed by the operation unit 250 of the mobile phone 200.

  FIG. 9A is a flowchart showing a flow of an example of control processing on the camera 10 side in the seventh embodiment, and FIG. 9B is a flow of an example of control processing on the mobile phone 200 side in the seventh embodiment. It is a flowchart which shows. The control process of FIG. 9A is performed by the CPU 42 of the camera 10, and the control process of FIG. 9B is performed by the CPU 242 of the mobile phone 200.

  In FIG. 9A, it is determined whether or not the notification function is turned on with reference to the notification function switching instruction stored in the EEPROM 48 of the camera 10 (step S702), and when the notification function is turned on. The radio communication unit 70 of the camera 10 transmits a radio wave having a specific frequency (specific radio wave) at regular cycle time intervals (step S704). For example, a specific radio wave is transmitted at a frequency used in short-range wireless communication. If the notification function is off, radio wave transmission (step S704) is not performed.

  In FIG. 9B, the mobile phone 200 refers to the notification function switching instruction in the EEPROM 248 of the mobile phone 200 to determine whether or not the notification function is on (step S732), and the notification function is on. In step S736, a distance determination threshold value is read from the EEPROM 248 of the mobile phone 200 (step S734), and the presence / absence of a specific radio wave transmitted from the wireless communication unit 70 of the camera 10 and the radio wave intensity (for example, electric field intensity) are detected. ) Based on the detection result, it is determined whether or not the distance between the camera 10 and the mobile phone 200 is a long distance (step S738).

  Specifically, if there is a specific radio wave and the radio field intensity is greater than the threshold, it is determined as a short distance, and if there is a specific radio wave and the electric field strength is less than the threshold or there is no specific radio wave, Judge as distance. Here, “there is no specific radio wave” means that the intensity of the radio wave of the specific frequency is smaller than the lowest detectable value.

  When it is determined that the distance between the camera 10 and the mobile phone 200 is a long distance, sound output by the speaker 264 of the mobile phone 200, vibration generation by the vibrator 266, and light emission by the light source 268 are performed simultaneously (step S740).

  The mobile phone 200 and the camera 10 are registered in advance by short-range wireless communication or the like, and the mobile phone 200 detects only a specific radio wave from the camera 10 of the owner.

  Moreover, the threshold value for distance determination can be designated by a distance (for example, in meters) using the operation unit 250 of the mobile phone 200. Specifically, when a setting screen for setting a threshold for determining a distance is displayed on the display unit 230 of the mobile phone 200, the user performs an input operation for designating how many [m] is a long distance. Do. The CPU 242 of the mobile phone 200 stores the distance threshold specified by the user in the EEPROM 248 of the mobile phone 200. Note that the EEPROM 248 of the mobile phone 200 stores in advance table information indicating the correspondence between the distance and the radio wave intensity. In the distance determining step (step S736), the radio field intensity threshold corresponding to the distance threshold is acquired based on the table information described above, and it is determined whether the distance is a long distance or a short distance.

  When the user designates a distance threshold, the radio field intensity threshold corresponding to the distance threshold may be acquired from the table information and stored in the EEPROM 248.

  The notification function switching instruction indicating whether the notification function is on or off may be input using the operation unit 50 (switch, GUI interface, etc.) of the camera 10, or the operation unit 50 (GUI interface, etc.) of the mobile phone 200. May be used. When a notification function switching instruction is input from the mobile phone 200, the mobile phone 200 transmits a notification function switching instruction to the camera 10 by wireless communication. The notification function switching instruction received by the camera 10 is stored (set) in the EEPROM 48 of the camera 10. When the notification function switching instruction indicates that the notification function is off, the camera 10 does not transmit a specific radio wave, and the mobile phone 200 does not monitor the specific radio wave. Thereby, the mobile phone 200 does not issue a warning.

  In the present embodiment, the leaving state of the camera 10 is detected using the radio wave transmission function originally installed in the camera 10 and the radio wave detection function originally installed in the mobile phone 200, and is originally installed in the mobile phone 200. Since the alarm is issued using the speaker 264, the vibrator 266, and the light source 268, the effect of preventing misplacement can be exhibited without increasing the cost of hardware.

[Eighth Embodiment]
In the eighth embodiment, when the camera 10 is in a power-on state, the CPU 42 of the camera 10 in FIG. 1 detects whether the camera 10 has moved by the camera shake detection sensor 74 of the camera 10 and sets the timer 76 of the camera 10. 2 is used to count the stationary time of the camera 10, and when the stationary time exceeds a certain time, the wireless communication unit 70 of the camera 10 notifies the mobile phone 200 of FIG. 2 wirelessly.

  FIG. 10 is a flowchart illustrating an exemplary flow of control processing of the camera 10 according to the eighth embodiment. This control process is performed by the CPU 42 of the camera 10.
