1.2 Operation 1.2.1 Tablet PC3
First, the operation of the tablet PC 3 will be briefly described.

  The operation mode of the tablet PC 3 according to the present embodiment can be switched according to the tilt angle of the tablet PC 3.

  As shown in FIG. 5, in the present example, the inclination angle of the tablet PC 3 with respect to the ground (D1-D2 plane) is set to θ. When the inclination angle θ is 0 ° ≦ θ ≦ 45 ° with respect to the ground, that is, a state where the display unit 10 and the camera 11 of the tablet PC 3 are nearly parallel to the ground is referred to as a first inclination angle. The sensor 34 of the tablet PC 3 detects the tilt angle of the tablet PC 3, generates a signal (value) based on the detected angle, and transmits the signal (value) to the control circuit 30. When the control circuit 30 determines that the tilt angle of the tablet PC 3 is the first tilt angle, the control circuit 30 enters an operation mode in which the user can operate.

  As shown in FIG. 6, when the inclination angle θ is 45 ° <θ ≦ 90 ° with respect to the ground, that is, when the display unit 10 and the camera 11 of the tablet PC 3 are almost perpendicular to the ground, the second inclination angle Notation. When the control circuit 30 determines that the tilt angle of the tablet PC 3 is the second tilt angle, the control circuit 30 enters a shooting mode to start shooting a moving image of the subject.

  For example, the control circuit 30 sets the threshold (first value) to a value (45 ° in this example) that is a boundary between the first tilt angle and the second tilt angle as a method of determining the tilt angle, and supplies the threshold value (first value) from the sensor 34. The first tilt angle and the second tilt angle may be determined based on whether a signal (detected value) is larger than a threshold value.

  Note that the first inclination angle and the second inclination angle described above are merely examples, and can be arbitrarily changed.

  Hereinafter, rehabilitation using such a tablet PC 3 will be described.

1.2.2 Rehabilitation 1.2.2.1 Rehabilitation Imaging Next, a flow of rehabilitation imaging will be described with reference to FIGS. 7 to 10.

  As shown in FIG. 7, the control circuit 30 of the tablet PC 3 determines whether the inclination angle θ is equal to the first inclination angle (Step S10). For example, the user tilts the tablet PC 3 to perform rehabilitation. When the tilt angle θ of the tablet PC 3 is at the first tilt angle (step S10_Yes), the tablet PC 3 enters an operation mode in which the user can operate. The control circuit 30 automatically enters the operation mode by inclining the tablet PC 3. However, the control circuit 30 may be configured to manually switch to the operation mode. Specifically, when the tilt angle θ of the tablet PC 3 is the first tilt angle, the control circuit 30 causes the display unit 10 to display a screen on which an operation mode can be selected. When the user selects an operation mode via the display unit 10, the control circuit 30 shifts to the operation mode.

  The user inputs the ID (identification number) of the person to be rehabilitated to the tablet PC 3 and logs in (step S11). For example, an ID is registered for each subject in the memory 31 of the tablet PC 3, and personal information (name of the subject, subject identification number, age, state, past shooting, etc.) is stored in the ID of the subject. Recording, photographing conditions, etc.). That is, when the user logs in with the ID of the target person, the personal information regarding the target person is accessed to the control circuit 30. If the target person wears an arbitrary terminal (for example, a wearable device), the ID of the target person may be registered in the terminal. In this case, in step S11, the ID of the target person is transmitted to the moving image recording apparatus 1 by operating the terminal by the target person. Then, for example, the tablet PC 3 may log in as the target person by receiving the transmitted target person ID.

  When the control circuit 30 logs in with the ID of the subject, the control circuit 30 causes the display unit 10 to display a shooting mode selection screen. When the user selects the shooting mode displayed on the display unit 10 (step S12), the control circuit 30 shifts to the selected shooting mode.

  The control circuit 30 displays a subject's action category selection screen on the display unit 10 in order to allow the user to select an action category (step S13).

  Next, an operation category selection screen will be described with reference to FIG. As shown in FIG. 8, for example, on the display unit 10, an operation category selection screen 110, a personal identification information (user name (name of the subject) and a user No. (identification number of the subject)) display area 111, and “return” Button 112 and a logout button 113 are displayed. In the example of FIG. 8, the motion category is divided into “seated motion”, “standing motion”, “standing motion”, “walking motion”, and “other”, and the user selects one of them. For example, the “sitting position operation” is selected when the target person performs an operation using his hands while sitting on a chair. "Standing motion" is selected when the target person sits on a chair or stands up. “Standing motion” is selected when the subject moves his or her body while standing up. "Walking action" is selected when the subject performs walking training.

  Here, an example of the operation category selection screen has been described. However, the category on the operation category selection screen can be changed (for example, added). As a method of changing the category, the setting screen stored in the memory 31 is displayed on the display unit 10 and the category can be changed by operating the user. This makes it possible to create a category to be used in each facility as an original, which leads to a further reduction in selection time and the like.

  Further, the control circuit 30 allows the user to select an operation category, but the present invention is not limited to this. For example, the control circuit 30 may automatically select an appropriate operation category. For example, the control circuit 30 may detect, via the camera 11, a device (equipment) used for rehabilitation, the posture of the subject, and the like, predict the content of rehabilitation to be performed, and automatically select the content.

  Returning to FIG. 7, the continuation of step S12 will be described. When an operation category is selected by the user (step S13), the control circuit 30 refers to the memory 31 and checks whether there is moving image data of the subject in the selected operation category in the past (step S14). .

  If there is no moving image data of the subject in the past (step S14_No), or if it is desired to change the camera position and newly set the camera position, the user manually sets the camera position. When the user sets the camera position, the control circuit 30 records information on the camera position in the memory 31 (step S15).

  Next, the operation screen of the camera position will be described with reference to FIG. As shown in FIG. 9, for example, when the camera position is manually set, an operation screen 120 is displayed on the display unit 10. The user operates the operation screen 120 to set the camera position. More specifically, for example, on the operation screen 120, the body position (trolley 4), the tablet PC 3 (camera 11), and the camera 12 are displayed as the parts, and the items of the height, angle, and spatial position of each are displayed. Touch the arrow to operate. In each item, a moving amount by manual operation, a current position, and a past set position are displayed. After setting the camera position, these numerical values are recorded as camera position information. Here, an example of the operation screen of the camera position has been described, but the present invention is not limited to this. For example, when the position information (previous value) at the time of the previous photographing is stored in the memory 31, the control circuit 30 may display the previous value on the operation screen of the camera position. As a result, the position at the time of the previous photographing can be easily confirmed. As another example, the control circuit 30 may calculate the difference between the previous position information and the current position information, and display the moving direction and the position on the operation screen of the camera position.

  Returning to FIG. 7, the continuation of step S14 will be described. If there is data photographed in the past (step S14_Yes), the control circuit 30 first retrieves past camera position information from the memory 31 (step S16). The control circuit 30 calls the position information on the operation category selected in step S13. For example, if the action category selected in step S13 is “walking”, the past position information of “walking” is called. When walking and sitting, the shooting distance and angle are different. Therefore, the required position information differs for each category.

  Next, the control circuit 30 acquires current position information from the sensors 42, 62, 82, and 34 (step S17). The control circuit 30 calls the position information on the operation category selected in step S13. For example, if the action category selected in step S13 is “walking”, the past position information of “walking” is called.

  Subsequently, the continuation of step S17 in FIG. 7 will be described with reference to FIG. As shown in FIG. 10, the control circuit 30 calculates a difference between the past position information and the current position information (Step S18).

  When the difference between the past position information and the current position information is equal to or larger than a predetermined allowable range (step S19_Yes), the control circuit 30 calculates a necessary movement amount of the moving image recording device 1 and moves the camera position. (Step S20). More specifically, the control circuit 30 controls the moving device 41 and the driving devices 43, 61, 63, and 81 to adjust the camera position to past position information. Thereafter, the control circuit 30 returns to Step S17. The control circuit 30 repeats steps S17 to S20 until the difference between the current position information and the past position information falls within a preset allowable range. In addition, for example, in order to adjust the positional relationship between the subject and the camera 11 or 12, the control circuit 30 may guide the subject to move by a voice guide or a guidance display on the display unit 10. . Further, the position may be manually adjusted so that the user falls within the allowable range.

  When the difference between the past position information and the current position information is within a preset allowable range (step S19_No), or when the user sets the camera position in step S15, the control circuit 30 30 determines whether the inclination angle θ is equal to the second inclination angle (step S21).

  When the control circuit 30 determines that the tilt angle θ is the second tilt angle (step S21_Yes), the control circuit 30 starts capturing a moving image (step S22).

  The control circuit 30 automatically enters the operation mode by setting the tablet PC 3 at an arbitrary angle. However, the control circuit 30 may be configured to manually start capturing a moving image. Specifically, when the tilt angle θ of the tablet PC 3 is at the second tilt angle, the control circuit 30 causes the display unit 10 to display a screen from which it is possible to select to start capturing a moving image. The control circuit 30 starts photographing a moving image by the user selecting to start photographing a moving image via the display unit 10.

  Note that the camera used for capturing moving images may be the camera 11 of the tablet PC 3 or the camera 12 installed on the apparatus main body 2 and may be set as appropriate according to the operation category and the like. Note that, for example, when “walking motion” is selected in the motion category, the control circuit 30 may move the moving image recording device 1 as the subject walks.

  More specifically, for example, the control circuit 30 measures the distance between the subject performing the walking exercise and moves the moving image recording device 1 so that the target person and the moving image recording device 1 maintain a certain distance. You may let it. Then, the control circuit 30 may measure the walking distance, the moving time, and the like of the target person together with the moving image shooting.

  In addition, for example, the moving image recording device 1 may be a target of walking practice. When using the moving image recording device 1 as a target of walking practice, the control circuit 30 moves the moving image recording device 1 at a preset speed, and shows that the subject is practicing walking toward the moving image recording device 1. You may take a picture. Further, the control circuit 30 measures the distance between the moving image recording device 1 and the subject, and if the subject is late, interrupts the movement of the moving image recording device 1 and performs voice change or the like to encourage walking. Is also good. Further, the control circuit 30 may measure the walking distance and the moving time of the subject.

  When the moving image shooting is completed, the control circuit 30 stores the moving image data and the camera position information in the memory 31 by classifying the moving image data and the camera position information, for example, by subject and motion category (step S23).

1.2.2.2 Video Editing and Reproduction of Rehabilitation Next, editing and reproduction of a video captured in rehabilitation will be described with reference to FIGS. In the present embodiment, a case where two moving images can be simultaneously reproduced on the display unit 10 will be described.

  As shown in FIG. 11, the control circuit 30 of the tablet PC 3 determines whether the tilt angle θ is equal to the first tilt angle (Step S30). For example, the user tilts the tablet PC 3 in order to edit and play back a moving image taken in rehabilitation. When the tilt angle θ of the tablet PC 3 is at the first tilt angle (step S30_Yes), the tablet PC 3 enters an operation mode in which the user can operate the tablet PC 3. The control circuit 30 automatically enters the operation mode by inclining the tablet PC 3. However, the control circuit 30 may be configured to manually switch to the operation mode. Specifically, when the tilt angle θ of the tablet PC 3 is the first tilt angle, the control circuit 30 causes the display unit 10 to display a screen on which an operation mode can be selected. When the user selects an operation mode via the display unit 10, the control circuit 30 shifts to the operation mode.

  For example, the user inputs the target person's ID into the tablet PC 3 and logs in (step S31).

  When the reproduction mode is selected by the user (step S32), the control circuit 30 shifts to the reproduction mode.

  In step S30, when the mode is shifted to the operation mode and the user logs in, the control circuit 30 may automatically shift to the reproduction mode.

  The control circuit 30 displays a playback moving image selection screen on the display unit 10.

  The reproduction moving image selection screen will be described with reference to FIG. As shown in FIG. 12, for example, the display unit 10 displays a playback moving image selection screen 130. For example, in the upper row of the playback moving image selection screen 130, the user No. And the user name are displayed. For example, the moving image data is classified by date, and the operation category and the shooting time of each moving image data are displayed on each date. In the example of FIG. 9, one or a plurality of moving image data in each time zone is surrounded by different frames in the morning and the afternoon in order to make it easier to determine the shooting time in the morning and the afternoon.

  Returning to FIG. 11, the continuation of step S32 will be described. For example, one or two moving images are selected by the user (step S33).

  When two moving images are selected, that is, when comparing the two moving images (Step S34_Yes), the control circuit 30 performs a moving image synchronization process (Step S35). More specifically, the control circuit 30 sets the start point of synchronous reproduction for the two moving images so that the movement of the target person in the two moving images is easy to compare, so that the timing of the movement of the target person is the same. . The user may manually set the start point of the synchronized playback while watching the playback moving image.

  After completion of the synchronization processing in step S35, or when only one moving image has been selected and there is no moving image to be compared (step S34_No), the screen shifts to a moving image reproduction screen.

  The control circuit 30 reproduces the moving image according to the operation of the user (step S36).

  The reproduction screen will be described with reference to FIG. As shown in FIG. 11, for example, the display unit 10 displays a playback screen 140 corresponding to the first moving image data, a playback screen 141 corresponding to the second moving image data, and a display area 142 of the operation button. Have been. For example, below the playback screens 140 and 141, seek bars for the respective image data are provided, and the current playback position and the start position of synchronous playback are shown on the seek bar. The operation button display area 142 includes, for example, a play button, a forward skip button, a slow play button, a synchronous play button, a moving image selection button, and an end button. When the user turns on the synchronous reproduction button, the display unit 10 displays two moving images reproduced from the synchronous reproduction start position. For example, by comparing the past moving image data with the latest moving image data by synchronous reproduction, it becomes easy to confirm the recovery status of the target person due to rehabilitation.

1.3 Effects According to the Present Embodiment With the configuration according to the present embodiment, the control device can capture an image of a subject without waiting for the subject. Hereinafter, this effect will be described in detail.

  The treatment time in rehabilitation may be limited. Therefore, it is desirable that the subject be substantially rehabilitated for as long as possible. As described above, there is a method in which the motion of the rehabilitation target person is captured by the moving image recording device during the rehabilitation.
