Can be obtained. The operation of this electronic device system 60 will be described below. Hereinafter, the camera used by the electronic device 1 for photographing may be referred to as “used camera”.

  FIG. 8 is a flowchart showing an example of the operation of the electronic device 1 when the electronic device 1 starts moving image shooting. As shown in FIG. 8, in step s1, when the touch panel 140 detects an execution instruction operation that instructs execution of the camera application, the control unit 100 reads and executes the camera application in the storage unit 150 in step s2. To do. When the camera application is executed, in step s3, the control unit 100 causes the camera in use to start shooting a moving image. The user can instruct the electronic device 1 to use the in-camera 190 or the out-camera 200 by operating the display area 11.

  After step s3, in step s4, the display unit 120 displays a through image captured by the camera in use under the control of the control unit 100. The through image is a moving image for the user to check in real time a subject within the shooting range of the camera used. The through image is also called a live view image or a preview image. The moving image shot by the camera in use is temporarily stored in the volatile memory 151. The control unit 100 reads a moving image from the volatile memory 151 and displays it on the display unit 120 as a through image.

  Next, in step s5, when the touch panel 140 detects a save start instruction operation for instructing to start saving a moving image shot by the camera in use, in step s6, the control unit 100 displays a moving image shot by the camera in use. , Storage in the nonvolatile memory 152 is started. In addition, the control unit 100 causes the display unit 120 to display a moving image stored in the nonvolatile memory 152. The save start instruction operation can also be said to be a shooting start operation for instructing start of shooting a moving image stored in the nonvolatile memory 152. As the storage start instruction operation, for example, an operation (for example, a tap operation) on a button displayed on the display unit 120 is employed. This button is sometimes called a shooting start button in a mobile phone, a digital camera, or the like. Hereinafter, unlike a through image, a moving image that is stored in the non-volatile memory 152 and shot by the camera in use may be referred to as a “saving target moving image”.

  After step s6, in step s7, the control unit 100 causes the wireless communication unit 210 to transmit an operation start instruction that instructs the wearable device 50 to start the operation.

  Thereafter, when the wireless communication unit 210 receives a still image processing execution instruction from the wearable device 50 in step s8, the control unit 100 performs still image processing in step s9. The process in step s9 will be described in detail later.

  FIG. 9 is a flowchart illustrating an example of the operation of the wearable device 50 when the wearable device 50 receives an operation start instruction from the electronic device 1. As illustrated in FIG. 9, when the wireless communication unit 510 receives an operation start instruction from the electronic device 1 in step s501, the information detection unit 550 starts detecting subject-related information in step s502. In step s502, the operation of the acceleration sensor 530 starts, and the speed calculation unit 501 obtains the speed of the subject 70 based on the acceleration detected by the acceleration sensor 530. When the detection of the subject related information starts, the information detection unit 550 continuously detects the subject related information.

  When detection of the subject related information starts, in step s503, the determination unit 502 determines whether the subject related information satisfies a predetermined condition. The determination unit 502 repeatedly executes step s503 until it is determined that the subject-related information satisfies a predetermined condition.

  The predetermined condition in step s503 is, for example, a condition that the speed of the subject 70 increases rapidly. In this case, in step s503, the determination unit 502 determines whether or not the speed of the subject 70 has suddenly increased. The determination unit 502 determines, for example, the speed of the subject 70 obtained slightly earlier than the latest speed of the subject 70 obtained by the speed calculation unit 501 (for example, the speed of the subject 70 obtained immediately before). The difference value obtained by subtracting (S) is obtained. Then, the determination unit 502 determines that the speed of the subject 70 has suddenly increased if the obtained difference value is greater than a predetermined positive threshold value. That is, the determination unit 502 determines that the speed of the subject 70 satisfies a predetermined condition. On the other hand, the determination unit 502 determines that the speed of the subject 70 does not satisfy the predetermined condition if the obtained difference value is equal to or less than the predetermined threshold value. The method for determining whether or not the speed of the subject 70 has suddenly increased is not limited to this.

  If it is determined in step s503 that the subject-related information satisfies the predetermined condition, the communication control unit 503 causes the wireless communication unit 510 to transmit an execution instruction instructing execution of the still image processing in step s504. Thereafter, step s503 is executed again, and it is determined whether or not the subject-related information satisfies a predetermined condition. The wearable device 50 repeatedly executes steps s503 and s504 until an operation end instruction to be described later is received from the electronic device 1.

  When the electronic device 1 receives the execution instruction from the wearable device 50 in step s8, the electronic device 1 performs still image processing in step s9. Each time the electronic device 1 receives an execution instruction from the wearable device 50 (step s8), the electronic device 1 executes still image processing (step s9).

  In the still image processing, for example, the control unit 100 causes the camera in use that is capturing the storage target moving image to interrupt the moving image capturing and capture the still image. The control unit 100 stores a still image captured by the camera in use in the nonvolatile memory 152. When the camera in use finishes shooting the still image, the control unit 100 causes the camera to restart shooting of the storage target moving image. In the still image processing, the control unit 100 may cause the camera to be used to shoot only one still image or a plurality of still images.

  In addition, in the still image processing, the control unit 100 may treat a part of the save target moving image captured by the camera used as a still image. For example, when the wireless communication unit 210 receives an execution instruction from the wearable device 50, the control unit 100 stores the frame image captured by the camera used at that time in the nonvolatile memory 152 as a still image. In the still image processing, when a part of the save target moving image captured by the camera used is handled as a still image, the moving image shooting by the camera used is not interrupted. In the still image processing, the control unit 100 may store only one frame image captured by the used camera in the nonvolatile memory 152 as a still image, or each of the plurality of frame images captured by the used camera is stationary. The image may be stored in the nonvolatile memory 152 as a picture.

  If the subject-related information satisfies a predetermined condition, the still image processing is executed, and hence the predetermined condition is hereinafter referred to as “execution condition”.

  FIG. 10 is a flowchart showing the operation of the electronic device 1 when the electronic device 1 finishes saving the moving image shot by the camera used. As illustrated in FIG. 10, when the touch panel 140 detects a storage end instruction operation instructing to end the saving of the moving image shot by the camera in use in Step s11, the control unit 100 uses the operation in Step s12. The storage of the moving image shot by the camera in the nonvolatile memory 152 is terminated. The save end instruction operation can be said to be a shooting end operation for instructing the end of shooting of a moving image stored in the nonvolatile memory 152. As the storage end instruction operation, for example, an operation (for example, a tap operation) on a button displayed on the display unit 120 is employed. This button may be called a shooting end button in a mobile phone, a digital camera, or the like.

  After step s12, in step s13, the control unit 100 causes the wireless communication unit 210 to transmit an operation end instruction that instructs the wearable device 50 to end the operation.

  After step s13, in step s14, the control unit 100 reads the still image obtained by the still image processing from the nonvolatile memory 152 and causes the display unit 120 to display the still image. Thereafter, in step s15, when the touch panel 140 detects a display end instruction operation for instructing the end of still image display, the control unit 100 causes the display unit 120 to display a through image captured by the camera used in step s16. . Thereafter, when the touch panel 140 detects a storage start instruction operation (step s5), the electronic device 1 executes step s6, and thereafter the electronic device 1 operates similarly.

  The control unit 100 may display a still image read from the nonvolatile memory 152 on the display unit 120 for a certain period of time and then display a through image captured by the camera in use on the display unit 120.

  FIG. 11 is a flowchart illustrating an example of the operation of the wearable device 50 when the wearable device 50 receives an operation end instruction from the electronic device 1. As shown in FIG. 11, when the wireless communication unit 510 receives an operation end instruction from the electronic device 1 in step s511, the information detection unit 550 ends detection of subject-related information in step s512. In step s512, the operation of the acceleration sensor 530 is stopped. Thereafter, when the wearable device 50 receives an operation start instruction from the electronic device 1 (step s501), the wearable device 50 executes step s502, and thereafter operates similarly.

  Unlike the above example, the wearable device 50 may always detect subject-related information without an instruction from the electronic device 1. In this case, the electronic device 1 does not execute the still image processing even if the execution instruction is received when the saving target moving image is not captured by the camera in use. When the wearable device 50 starts detecting subject-related information when receiving an operation start instruction and ends detecting subject-related information when receiving an operation end instruction as in the above example, the power consumption of the wearable device 50 Can be reduced.

  Further, in the above example, the still image processing is executed when the saving target moving image is shot. However, the still image processing may be executed when the through image is shot. FIG. 12 is a flowchart showing an example of the operation of the electronic device 1 in this case.

  As shown in FIG. 12, when the above steps s1 to s4 are executed, the control unit 100 causes the wireless communication unit 210 to transmit an operation start instruction in step s21. The wearable device 50 operates in the same manner as described above when receiving the operation start instruction.

  Thereafter, when the wireless communication unit 210 receives an execution instruction from the wearable device 50 in step s22, the control unit 100 executes still image processing in step s23. In step s24, the control unit 100 reads the still image obtained by the still image processing from the nonvolatile memory 152 and causes the display unit 120 to display the still image instead of the through image. Thereafter, in step s25, when the touch panel 140 detects a display end instruction operation for instructing the end of display of the still image, the control unit 100 displays a through image captured by the camera in use instead of the still image in step s26. Display on the unit 120. Every time the electronic device 1 receives an execution instruction (step s22), the electronic device 1 executes steps s23 to s26. The electronic device 1 repeatedly executes steps s22 to s26 while displaying the through image.

  The control unit 100 displays the still image read from the nonvolatile memory 152 on the display unit 120 for a certain period of time instead of the through image, and then displays the through image captured by the camera in use instead of the still image. May be displayed. In addition, the control unit 100 may display the still image read from the nonvolatile memory 152 on the display unit 120 so as to overlap the through image.

  When still image processing is executed when a through image is shot, when touch panel 140 detects a save start instruction operation (step s5), step s7 is not executed after step s6.

  As described above, the wearable device 50 transmits a still image processing execution instruction to the electronic device 1 when it is determined that the subject-related information satisfies the execution condition. The electronic device 1 performs still image processing when the wireless communication unit 210 receives a still image processing execution instruction during moving image shooting with the camera. Therefore, the electronic device 1 can automatically obtain a still image in which the subject 70 in a desired state is captured while shooting a moving image of the subject 70. The subject-related information and execution conditions detected by the wearable device 50 are determined according to what state it is desired to obtain a still image of the subject 70.

  In this example, the wearable device 50 transmits a still image processing execution instruction to the electronic device 1 when the speed of the subject 70 increases rapidly. For this reason, the electronic device 1 can obtain a still image of the subject 70 whose speed has been increased rapidly when shooting a moving image of the subject 70. For example, as illustrated in FIG. 2, when the subject 70 on which the electronic device 1 is running is shot with a moving image, if the speed at which the subject 70 runs rapidly increases, the electronic device 1 causes the subject 70 at that time to increase. A still image is obtained. As a specific scene, for example, when the parent causes the electronic device 1 to shoot a movie of a child running with the wearable device 50 attached to the head or torso at a children's athletic meet, When the running speed suddenly increases, the electronic device 1 automatically obtains a still image showing the child at that time.

  By changing the execution condition and the subject-related information, still images of the subject 70 in various states can be obtained. For example, consider adopting a condition that the speed of the subject 70 is close to zero as an execution condition. In this case, for example, when the electronic device 1 is shooting a moving image of a snowboarder attached to the head or torso of the wearable device 50, the snowboarder jumps and is determined by the top of the jump. When a pose is performed, a still image can be obtained.

  Also, consider that the wearable device 50 detects the acceleration of the subject 70 as subject-related information, and adopts a condition that the magnitude of the acceleration of the subject 70 suddenly decreases as an execution condition. In this case, for example, when the electronic device 1 is shooting a video of a volleyball player with the wearable device 50 attached to his arm jumping and hitting an attack, a still image showing the moment when the volleyball player hits the attack Can be obtained. When the acceleration of the subject 70 is employed as the subject-related information, the wearable device 50 does not require the speed calculation unit 501 and the information detection unit 550 is configured only by the acceleration sensor 530.

  The subject related information and execution conditions are not limited to the above example. Further, the mounting location of the wearable device 50 on the subject 70 is not limited to the above example.

<Various modifications>
Various modifications of the electronic device system 60 will be described below.

<First Modification>
In the above example, the wearable device 50 determines whether or not the subject related information satisfies the execution condition, but the electronic device 1 may determine whether or not the subject related information satisfies the execution condition. FIG. 13 is a diagram illustrating an example of functional blocks of the processor 500 of the wearable device 50 according to the present modification.

  As illustrated in FIG. 13, the processor 500 according to the present modification does not include the determination unit 502 unlike the configuration illustrated in FIG. 7 described above. In this modified example, every time the speed calculation unit 501 determines the speed, the communication control unit 503 causes the wireless communication unit 510 to transmit the determined speed. In other words, the communication control unit 503 causes the wireless communication unit 510 to transmit the detected subject-related information every time the information detection unit 550 detects the subject-related information.

  FIG. 14 is a flowchart showing an example of the operation of the wearable device 50 according to this modification. As illustrated in FIG. 14, when the wireless communication unit 510 receives an operation start instruction from the electronic device 1 in step s521, in step s522, the information detection unit 550 detects subject-related information in the same manner as in step s502 described above. Start.

  When the detection of the subject related information starts, the wireless communication unit 510 starts transmission of the subject related information under the control of the communication control unit 503 in step s523. The wireless communication unit 510 transmits the detected subject related information to the electronic device 1 every time the subject detection information is detected by the information detection unit 550.

  FIG. 15 is a flowchart showing an example of the operation of the electronic apparatus 1 according to this modification. As shown in FIG. 15, in the electronic device 1, the above-described steps s1 to s7 are executed. Thereafter, in step s31, the wireless communication unit 210 starts receiving subject-related information transmitted from the wearable device 50.

  When reception of the subject related information starts, in step s32, the control unit 100 determines whether or not the subject related information satisfies the execution condition. The control unit 100 repeatedly executes step s32 until it is determined that the subject-related information satisfies the execution condition.

  If the control unit 100 determines in step s32 that the subject-related information satisfies the execution condition, the control unit 100 executes still image processing in step s33. Thereafter, step s32 is executed again, and it is determined whether or not the subject related information satisfies the execution condition. The electronic device 1 repeatedly executes steps s32 and s33 until a storage end instruction operation is detected on the touch panel 140.

  Note that the operation of the electronic device 1 when the electronic device 1 according to the present modification finishes saving the moving image shot by the camera used is the same as the operation shown in FIG. Further, the operation of the wearable device 50 when the wearable device 50 according to the present modification receives an operation end instruction from the electronic device 1 is the same as the operation illustrated in FIG. 11.

  Similarly to the above, still image processing may be executed when a through image is captured in this modified example. FIG. 16 is a flowchart showing an example of the operation of the electronic device 1 in this case. In the flowchart shown in FIG. 16, steps s31 to s33 are executed instead of steps s22 and s23 in the flowchart shown in FIG. 12, step s24 is executed after step s33, and step s32 is executed after step s26. Is to be executed. The electronic device 1 repeatedly executes steps s32, s33, s24, s25, and s26 while displaying the through image. When still image processing is executed when a through image is shot, when the touch panel 140 detects a save start instruction operation (step s5), steps s7 and s31 are not executed in the flowchart shown in FIG. Step s32 is executed immediately after step s6.

  As described above, in the present modification, the electronic device 1 executes the still image processing when the subject related information received by the wireless communication unit 210 during moving image shooting with the camera satisfies the execution condition. Accordingly, in the same manner as described above, the electronic device 1 can automatically obtain a still image in which the subject 70 in a desired state is captured while a moving image of the subject 70 is being captured.

<Second Modification>
FIG. 17 is a rear view showing an example of the appearance of the electronic apparatus 1 according to the present modification. FIG. 18 is a block diagram showing an example of the electrical configuration of the electronic apparatus 1 according to this modification.

  As shown in FIG. 18, the electronic apparatus 1 according to this modification includes a third camera 230. The third camera 230 includes a lens 231 and an image sensor. As shown in FIG. 17, not only the lens 201 of the second camera 200 but also the lens 231 of the third camera 230 is visible from the upper end of the back surface 1 b of the electronic device 1. The lens 201 of the second camera 200 and the lens 231 of the third camera 230 are arranged vertically, for example.

  The third camera 230 can capture a still image or a moving image based on control by the control unit 100 and output the still image or moving image to the control unit 100. Since the lens 231 of the third camera 230 is visible from the back surface 1 b of the electronic device 1, the third camera 230 can capture a subject existing on the back surface 1 b side of the electronic device 1. . Hereinafter, the second camera 200 and the third camera 230 may be referred to as “first out camera 200” and “second out camera 230”, respectively. In addition, when there is no need to particularly distinguish the in-camera 190, the first out-camera 200, and the second out-camera 230, each may be simply referred to as “camera”.

  The first out camera 200 is, for example, a camera that can shoot at a wider angle than the second out camera 230. Here, “a camera that can shoot at a wide angle” means that the first out camera 200 is the first out camera when both the lenses 201 and 231 of the second out camera 200 and the second out camera 230 are fixed focal angles. This means that the fixed angle of view of 200 is larger than the fixed angle of view of the second out camera 230. In addition, when the lens 201 of the first out camera 200 is a single focus lens and the lens 231 of the second out camera 230 is a zoom lens having a variable angle of view, the “camera capable of photographing at a wide angle” This means that the fixed angle of view of the first out camera 200 is larger than the maximum value of the variable angle of view of the second out camera 230. In addition, when the lens 201 of the first out camera 200 is a zoom lens and the lens 231 of the second out camera 230 is a single focus lens, the “camera that can shoot at a wide angle” refers to the first out camera 200. It means that the maximum value of the variable angle of view is larger than the fixed angle of view of the second out camera 230. When the lenses 201 and 231 of the first out camera 200 and the second out camera 230 are both zoom lenses, the “camera capable of photographing at a wide angle” is the maximum variable angle of view of the first out camera 200. This means that the value is larger than the maximum value of the variable angle of view of the second out camera 230.

  The electronic device 1 not only has a function of zooming the shooting range of the first out camera 200 (hereinafter referred to as “first shooting range”), but also the shooting range of the second out camera 230 (hereinafter referred to as “second shooting range”). Has a function of zooming. If the zoom magnification of the first out camera 200 is greater than or equal to the zoom magnification of the second out camera 230, the first shooting range is wider than the second shooting range and includes the second shooting range. On the other hand, when the zoom magnification of the first out camera 200 is smaller than the zoom magnification of the second out camera 230, the first shooting range may include the second shooting range, or the second shooting range may be the first shooting range. It may include the shooting range.

  In this modification, the number of pixels of the image sensor included in the second out camera 230 is larger than the number of pixels of the image sensor included in the first out camera 200, for example. The user can set the number of pixels of still images and moving images captured by the first out camera 200 and the second out camera 230 by operating the display area 11. Note that the number of pixels of the image sensor of the first out camera 200 and the number of pixels of the image sensor of the second out camera 230 may be the same.

  In this modification, in the still image processing executed when the camera unit including the first out camera 200 and the second out camera 230 is shooting a moving image, the other is different from the one camera that is shooting the moving image. The camera takes a still image.

  For example, in the example of FIGS. 8 and 12 described above, when the first out-camera 200 captures a moving image, when the wireless communication unit 210 receives an instruction to execute still image processing, the control unit 100 causes the second out camera 230 to capture a still image. In addition, when the second out camera 230 captures a moving image and the wireless communication unit 210 receives an instruction to execute still image processing, in the still image processing, the control unit 100 causes the first out camera 200 to capture a still image. Let's shoot.

  In the example of FIGS. 15 and 16 described above, when the first out-camera 200 captures a moving image, if the control unit 100 determines that the subject-related information satisfies the execution condition, in the still image processing, The second out camera 230 is caused to take a still image. In addition, when the second out-camera 230 captures a moving image, if the control unit 100 determines that the subject-related information satisfies the execution condition, the control unit 100 causes the first out-camera 200 to capture a still image in the still image processing. .

  Thus, in this modification, in a still image process when a camera having a camera unit including the first out camera 200 and the second out camera 230 is shooting a moving image, another camera in the camera unit is stationary. Take a picture. Therefore, the camera unit can shoot a still image without interrupting moving image shooting.

  In the still image processing when the first out-camera 200 is capturing a moving image, the control unit 100 may cause the first out-camera 200 to interrupt the capturing of the moving image and capture a still image. A part of the moving image shot by the out camera 200 may be handled as a still image. In addition, in the still image processing when the second out camera 230 is capturing a moving image, the control unit 100 may cause the second out camera 230 to interrupt the capturing of the moving image and capture the still image, or the second A part of the moving image shot by the out camera 230 may be handled as a still image.

  Hereinafter, a camera that captures a still image in still image processing may be referred to as a “still image capturing camera”. In addition, a camera that captures a moving image may be referred to as a “moving image capturing camera”. In still image processing when a certain camera is shooting a moving image, when the certain camera interrupts moving image shooting and shoots a still image, the moving image shooting camera and the still image shooting camera are the same. On the other hand, when a camera other than the certain camera shoots a still image in a still image processing when a certain camera is shooting a moving image as in this modification, the moving image shooting camera and the still image The camera is different from the camera.

<Third Modification>
In this modification, the electronic device 1 captures a still image in the still image processing. Then, the electronic device 1 determines the shutter speed when shooting a still image in the still image processing based on the speed of the subject 70 detected by the wearable device 50.

  For example, as in the example of FIGS. 8 and 12, when the electronic device 1 performs a still image process when receiving an execution instruction from the wearable device 50, the wearable device 50 causes the above-described step s504 of FIG. The latest speed obtained by the speed calculation unit 501 is transmitted to the electronic device 1 together with the execution instruction. When receiving an execution instruction from the wearable device 50, the control unit 100 causes the still image capturing camera to capture a still image in the still image processing. At this time, the control unit 100 determines the shutter speed when the still image capturing camera captures a still image based on the speed of the subject 70 received from the wearable device 50 together with the execution instruction. The control unit 100 increases the shutter speed when the still image capturing camera captures a still image as the speed of the subject 70 received from the wearable device 50 increases.

  15 and 16, when the electronic device 1 determines whether the subject-related information detected by the wearable device 50 satisfies the execution condition, the electronic device 1 When it is determined that the information satisfies the execution condition, in the still image processing, the shutter speed when the still image capturing camera captures a still image is determined based on the latest speed of the subject 70 received from the wearable device 50. . The control unit 100 increases the shutter speed when the still image camera captures a still image as the speed of the subject 70 increases.

  As described above, the shutter speed when the still image capturing camera captures a still image is determined based on the speed of the subject 70 detected by the wearable device 50, so that the subject 70 is blurred in the still image processing. Can be suppressed.

<Fourth Modification>
When it is determined that the subject-related information satisfies the execution condition, there is a possibility that the subject 70 does not exist within the shooting range of the still image shooting camera. Therefore, there is a possibility that the subject 70 is not shown in the still image obtained by the still image processing.

  Therefore, in this modification, the electronic device 1 performs still image processing when the subject 70 exists within the shooting range of the still image shooting camera, and the subject 70 does not exist within the shooting range of the still image shooting camera. Does not perform still image processing. FIG. 19 is a diagram illustrating an example of an electrical configuration of the electronic apparatus 1 according to the present modification. FIG. 20 is a diagram illustrating an example of an electrical configuration of the wearable device 50 according to this modification.

  As shown in FIG. 20, the wearable device 50 according to the present modification further includes a GPS receiver 560 in the configuration shown in FIG. The GPS receiver 560 has an antenna 561. The GPS receiver 560 can receive a radio signal from a GPS (Global Positioning System) artificial satellite using the antenna 561 and controlled by the processor 500. The GPS receiver 560 can calculate the current position of the wearable device 50 using, for example, latitude and longitude based on the received radio signal. Since the position of the wearable device 50 can be said to be the position of the subject 70 to which the wearable device 50 is attached, it can be said that the GPS receiver 560 can calculate the current position of the subject 70. The current position obtained by the GPS receiver 560 is input to the processor 500. The GPS receiver 560 functions as a position acquisition unit that acquires the current position of the subject 70.

  As shown in FIG. 19, the electronic apparatus 1 according to this modification further includes a GPS receiver 250 and a geomagnetic sensor 260 in the configuration shown in FIG. 5. The GPS receiver 250 has an antenna 251. The GPS receiver 250 can receive a radio signal from a GPS artificial satellite under the control of the control unit 100 using the antenna 251. The GPS receiver 250 can calculate the current position of the electronic device 1 using, for example, latitude and longitude based on the received radio signal. The current position obtained by the GPS receiver 250 is input to the control unit 100. The GPS receiver 250 functions as a position acquisition unit that acquires the current position of the electronic device 1. The geomagnetic sensor 260 can detect geomagnetism.

  The control unit 100 includes the geomagnetism detected by the geomagnetic sensor 260, the position of the electronic device 1 obtained by the GPS receiver 250, the position of the subject 70 obtained by the GPS receiver 560 of the wearable device 50, and the still image camera. It is possible to determine whether or not the subject 70 exists within the shooting range of the still image shooting camera on the basis of the angle of view. This point will be described later in detail.

  FIG. 21 is a diagram illustrating an example of the operation of the wearable device 50 according to the present modification. The flowchart shown in FIG. 21 corresponds to the flowchart shown in FIG. As illustrated in FIG. 21, when the wearable device 50 executes the above-described step s501, in step s531, the information detection unit 550 starts detecting subject-related information, and the GPS receiver 560 detects the position of the subject 70. Start acquisition.

  Next, in step s532, the determination unit 502 determines whether the subject-related information satisfies the execution condition. If it is determined in step s532 that the subject-related information satisfies the execution condition, in step s533, the communication control unit 503 instructs the execution of the still image processing and the latest position of the subject 70 acquired by the GPS receiver 560. Are transmitted to the wireless communication unit 510. The wearable device 50 repeatedly executes steps s532 and s533 until an operation end instruction is received from the electronic device 1.

  FIG. 22 is a diagram illustrating an example of the operation of the electronic apparatus 1 according to this modification. The flowchart shown in FIG. 22 corresponds to the flowchart shown in FIG. As illustrated in FIG. 22, the electronic device 1 executes steps s1 to s7. Thereafter, when the wireless communication unit 210 receives the execution instruction and the current position of the subject 70 from the wearable device 50 in step s41, in step s42, the control unit 100 determines that the subject 70 is within the shooting range of the still image shooting camera. It is determined whether or not it exists. In step s42, the control unit 100 identifies the direction in which the lens of the still image camera is facing, based on the geomagnetism detected by the geomagnetic sensor 260. In addition, the control unit 100 determines the distance between the subject 70 and the electronic device 1 based on the current position of the subject 70 received from the wearable device 50 and the current position of the electronic device 1 obtained by the GPS receiver 250. Ask. Then, the control unit 100 determines the direction in which the lens of the still image shooting camera is facing, the distance between the subject 70 and the electronic device 1, the current position of the subject 70 and the electronic device 1, and the current position of the still image shooting camera. Based on the angle of view, it is determined whether or not the subject 70 exists within the shooting range of the still image shooting camera.

  If the control unit 100 determines in step s42 that the subject 70 is within the shooting range of the still image shooting camera, the control unit 100 performs still image processing in step s43. On the other hand, when the control unit 100 determines in step s42 that the subject 70 does not exist within the shooting range of the still image shooting camera, in step s44, the control unit 100 determines not to perform still image processing. Every time the electronic device 1 receives an execution instruction from the wearable device 50 (step s41), the electronic device 1 executes steps s42 to s44.

  Thus, in this modification, the control unit 100 determines whether or not the subject 70 exists within the shooting range of the still image shooting camera during moving image shooting with the moving image shooting camera. When the wireless communication unit 210 receives a still image processing execution instruction during moving image shooting, the control unit 100 performs still image processing when determining that the subject 70 is within the shooting range of the still image shooting camera. On the other hand, when the wireless communication unit 210 receives a still image processing execution instruction during moving image shooting, the control unit 100 performs still image processing when determining that the subject does not exist within the shooting range of the still image shooting camera. Absent. Thereby, in the still image processing, it can be suppressed that a still image in which the subject 70 is not captured is obtained. Therefore, it is possible to suppress the wasteful image processing from being executed.

  Even when the still image processing is executed during the shooting of the through image, the control unit 100 determines whether the subject exists within the shooting range of the still image shooting camera based on the determination result. It may be determined whether or not to execute image processing. FIG. 23 is a flowchart showing an example of the operation of the electronic apparatus 1 in this case. In the flowchart shown in FIG. 23, steps s41 to s44 are executed instead of steps s22 and s23 in the flowchart shown in FIG. 12, and step s24 is executed after step s43.

  Even when the electronic device 1 determines whether the subject-related information satisfies the execution condition, the control unit 100 determines whether the subject exists within the shooting range of the still image shooting camera. Whether or not to execute still image processing may be determined based on the above. 24 and 25 are flowcharts showing examples of operations of the wearable device 50 and the electronic device 1 in this case.

  The flowchart shown in FIG. 24 corresponds to the flowchart shown in FIG. As illustrated in FIG. 24, when the wearable device 50 executes the above-described step s521, in step s541, the information detection unit 550 starts detecting the subject-related information, and the GPS receiver 560 detects the position of the subject 70. Start acquisition.

  Next, in step s542, the wireless communication unit 510 starts transmitting the detected subject-related information and starts transmitting the acquired position of the subject 70 under the control of the communication control unit 503. The wireless communication unit 510 transmits the detected subject-related information to the electronic device 1 every time the information detection unit 550 detects the subject-related information, and whenever the GPS receiver 560 acquires the position of the subject 70. The acquired subject position is transmitted to the electronic device 1.

  The flowchart shown in FIG. 25 corresponds to the flowchart shown in FIG. As illustrated in FIG. 25, when the electronic device 1 executes steps s1 to s7, in step s51, the wireless communication unit 210 starts receiving subject-related information and the position of the subject 70 transmitted from the wearable device 50. .

  Next, in step s52, the control unit 100 determines whether or not the subject related information satisfies the execution condition. If the control unit 100 determines that the subject-related information satisfies the execution condition, in step s53, the control unit 100 determines whether or not the subject 70 exists within the shooting range of the still image shooting camera. In step s53, the latest position of the subject received by the wireless communication unit 210 is used. When the control unit 100 determines that the subject 70 exists within the shooting range of the still image shooting camera, the control unit 100 performs still image processing in step s54. On the other hand, when determining that the subject 70 does not exist within the shooting range of the still image shooting camera, the control unit 100 determines not to perform still image processing in step s55. Thereafter, step s52 is executed again, and it is determined whether or not the subject-related information satisfies the execution condition. The electronic device 1 repeatedly executes steps s52 to s55 until the storage end instruction operation is detected on the touch panel 140.

  As described above, in the example of FIG. 25, when the control unit 100 determines that the subject-related information received by the wireless communication unit 210 during moving image shooting satisfies the execution condition, the subject 70 is within the shooting range of the still image shooting camera. If it is determined that the image is present, still image processing is performed. On the other hand, when the control unit 100 determines that the subject-related information received by the wireless communication unit 210 during moving image shooting satisfies the execution condition, the control unit 100 stops when determining that the subject does not exist within the shooting range of the still image shooting camera. Do not perform image processing. Thereby, in the still image processing, it can be suppressed that a still image in which the subject 70 is not captured is obtained. Therefore, it is possible to suppress the wasteful image processing from being executed.

  Note that even when the control unit 100 determines whether or not the subject-related information satisfies the execution condition and the still image processing is executed during shooting of the through image, the control unit 100 Whether or not still image processing is to be executed may be determined based on the determination result of whether or not the image is within the shooting range of the still image shooting camera. FIG. 26 is a flowchart showing an example of the operation of the electronic device 1 in this case. In the flowchart shown in FIG. 26, steps s51 to s55 are executed instead of steps s31 and s32 in the flowchart shown in FIG. 16, and step s33 is executed after step s54.
