For example, the sensor 42 measures a distance between the apparatus main body 2 and the subject 1000, grasps a spatial position of the apparatus main body 2 in a room where rehabilitation is performed, measures a traveling direction, a moving speed, and the like of the apparatus main body. 2 is provided for measuring the distance to the obstacle or detecting the collision with the obstacle so as not to collide with the obstacle while moving. For example, the sensor 42 includes a range sensor (laser sensor), a depth sensor (infrared sensor), a gyro sensor, an acceleration sensor, a pressure sensor, and the like. The data measured by the sensor 42 is transmitted to the tablet PC 3.

  Note that the moving image recording device 1 may have a GPS function without relying on the information of the sensor 42, and may grasp the spatial position of the device main body 2 based on the received position information signal. In addition, the moving image recording device 1 may receive image information of another camera installed in the room, for example, and grasp the spatial position by analyzing the received image information. Furthermore, the moving image recording apparatus 1 may measure the distance to the target person 1000 or the distance to an obstacle or the like based on image information from the camera 12 of the apparatus main body 2 and the camera 11 of the tablet PC 3.

  The driving device 43 of the lower support 5 drives the lower support 5 under the control of the tablet PC 3. For example, when the lower support 5 is an electric actuator, the driving device 43 of the lower support 5 includes a motor for the electric actuator, and the rod portion of the electric actuator, that is, the lower support 5 is arranged in the D3 direction perpendicular to the floor (the D3 direction is (A direction orthogonal to the D1 direction and the D2 direction). Further, for example, when the lower support 5 is a hydraulic cylinder, the driving device 43 of the lower support 5 includes an electric hydraulic pump.

  The lower support 5 is installed on the trolley 4, and a worktable 6 is installed on the upper surface thereof (see FIG. 2). The workbench 6 moves upward or downward due to expansion and contraction of the lower support 5. Note that the lower support 5 can be manually expanded and contracted when the power of the driving device 43 of the lower support 5 is in an OFF state. Further, the lower support 5 may have a structure such as a robot arm having six axes, for example.

  The worktable 6 includes a table 60, a table driving device 61, a sensor 62, and a driving device 63 of the upper support 7.

  As shown in FIG. 4, the tablet PC 3 is arranged on the table 60. The table 60 can arrange the tablet PC 3 at an arbitrary inclination angle (the inclination angle of the display screen with respect to the D1-D2 plane).

  The table driving device 61 includes a motor for adjusting the tilt angle of the tablet PC 3 on the table 60 under the control of the tablet PC 3. In addition, for example, the table driving device 61 may include a motor for moving the table 60 in the D1-D2 plane or rotating the work table 6. Note that the table driving device 61 may be eliminated, and the user may manually adjust the tilt angle of the tablet PC 3.

For example, the sensor 62 is provided to measure the distance between the work table 6 and the subject 1000, measure the tilt angle of the tablet PC 3, or measure the height of the work table 6 from the floor. For example, the sensor 62 includes a range sensor (laser sensor), a depth sensor (infrared sensor), a gyro sensor, an angle sensor, an altitude sensor, and the like. The data measured by the sensor 62 is transmitted to the tablet PC 3.

  The driving device 63 of the upper support 7 drives the upper support 7 under the control of the tablet PC 3. For example, when the upper support 7 is an electric actuator, the driving device 63 of the upper support 7 includes a motor for the electric actuator, and expands and contracts the rod portion of the electric actuator, that is, the upper support 7 in the D3 direction.

  As shown in FIG. 2, the upper support 7 is installed on a worktable 6, and a camera base 8 is installed on the upper surface thereof. The camera base 8 moves upward or downward due to expansion and contraction of the upper support 7. Note that the upper support 7 can be manually expanded and contracted when the power supply of the driving device 63 of the upper support 7 is turned off. Further, the upper support 7 may have a structure such as a robot arm having six axes, for example.

When the power of the camera driving device 81 is off, the position of the camera 12 can be manually adjusted. Note that the camera driving device 81 may have a function of rotating the camera 12 or moving the camera 12 to an arbitrary position.

  The sensor 82 of the camera base 8 is provided according to the purpose. For example, the sensor 82 is provided to measure the distance between the camera 12 and the subject 1000, measure the angle of the camera 12, or measure the height of the camera stand 8 from the floor. For example, the sensor 82 includes a range sensor (laser sensor), a depth sensor (infrared sensor), a gyro sensor, an angle sensor, an altitude sensor, and the like. The data measured by the sensor 82 is transmitted to the tablet PC 3.

  In this embodiment, the case where the control circuit 30 in the tablet PC 3 controls the entire apparatus main body 2 has been described. However, for example, a control unit (and a memory, a display unit, an operation unit, and the like) is provided on the workbench 6 and the like. The main unit 2 may be controlled by the control unit. In this case, for example, the apparatus main body 2 can operate even in a state where the tablet PC 3 is not present or a state where another operation is being performed on the tablet PC 3.

1.2 Shooting Mode Next, the flow of the shooting mode will be described with reference to FIGS.

  As shown in FIG. 5, for example, the user inputs the ID of the subject 1000 to be rehabilitated to the tablet PC 3 and logs in (step S10). For example, the ID of the subject 1000 is registered in the memory 31 of the tablet PC 3, and the ID of the subject 1000 includes personal information (name, age, state, past shooting record, Conditions). That is, by logging in with the ID of the target person 1000, personal information on the target person 1000 is read out to the control circuit 30. In addition, when the target person 1000 wears an arbitrary terminal (for example, a wearable device) and the ID of the target person 1000 is registered in the terminal, the moving image recording apparatus 1 transmits the target person 1000 transmitted from the arbitrary terminal. May be logged in as the target person 1000.

  When the photographing mode is selected by the user (step S11), the control circuit 30 shifts to the photographing mode.

  The control circuit 30 displays an operation category selection screen of the subject 1000 on the display unit 10 in order to allow the user to select an operation category (step S12).

  As shown in FIG. 6, for example, an operation category selection screen 110, personal identification information (user name (subject name) and user No. (subject identification number)) display area 111 are displayed on the display unit 10, and “return”. A button 112 and a logout button 113 are displayed. In the example of FIG. 6, 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 subject 1000 performs an operation using his hands while sitting on a chair. The “standing operation” is selected when the subject 1000 sits or stands on a chair. The “standing operation” is selected when the subject 1000 moves his or her body while standing up. “Walking action” is selected when the subject 1000 performs walking training. Note that the control circuit 30 may have a function of adding and editing an operation category. For example, as a method for changing the category, the control circuit 30 displays the setting screen stored in the memory 31 on the display unit 10 and operates the user to change the addition and editing of the operation category. Good. Thereby, for example, it becomes possible to create an operation category used in each facility in an original manner. Alternatively, it is possible to set, for example, contents with high frequency of rehabilitation according to the site of each facility. Therefore, it leads to shortening of the selection time by the user and reduction of the work load.

  Returning to FIG. 5, when an operation category is selected by the user (step S12), the control circuit 30 refers to the memory 31 and determines whether there is moving image data of the subject 1000 in the past in the selected operation category. Confirm. Note that the control circuit 30 may store camera position information for each subject's motion category because the camera position differs depending on the motion category even for the same subject.

  If there is no moving image data of the subject 1000 in the past (step S13_NO), or if it is desired to change the camera position and set a new one, the user manually sets the camera position. When the user sets the camera position, the control circuit 30 records the camera position information in the memory 31 (Step S14).

  As shown in FIG. 7, 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. When the setting of the camera position is completed, these numerical values are recorded as one piece of 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.

  Referring back to FIG. 5, when there is data captured in the past (step S13_YES), the control circuit 30 first retrieves past camera position information from the memory 31 (step S15). More specifically, the control circuit 30 calls up camera position information relating to the operation category selected in step S12. For example, if the motion category selected in step S12 is “walking motion”, the camera position information of the past “walking motion” is called. For example, the shooting distance and the angle differ between the walking motion and the sitting motion. Therefore, the required camera position information differs for each operation category.

  Next, the control circuit 30 acquires current position information from the sensors 42, 62, 82, and 34 (step S16).

  As shown in FIG. 8, the control circuit 30 calculates a difference between the past position information and the current position information (Step S17).

  If the difference between the past position information and the current position information exceeds the preset allowable range (step S18_YES), the control circuit 30 calculates the necessary moving amount of the moving image recording device 1 and determines the camera position. It is moved (step S19). 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 S16. The control circuit 30 repeats steps S16 to S19 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 camera 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 S18_NO), or after the user sets the camera position in step S14, the control circuit 30 starts moving image shooting. It is possible. Then, the control circuit 30 captures a moving image according to, for example, a screen operation on the tablet PC 3 by a user, an operation using a remote controller, or a voice operation (step S20). 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 the control circuit 30 may move the video recording device 1 as the subject 1000 walks, for example, when “walking motion” is selected in the motion category. More specifically, for example, the control circuit 30 measures the distance between the subject 1000 performing the walking exercise and the moving image recording device 1 so that the subject 1000 and the moving image recording device 1 maintain a certain distance. May be moved. Then, the control circuit 30 may measure the walking distance, the moving time, and the like of the target person 1000 together with the moving image shooting.

  Further, for example, the moving image recording device 1 may be used as a target for walking practice. When the subject 1000 sets 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 the subject 1000 performs walking training toward the moving image recording device 1. You may take a picture of what you are doing. Further, the control circuit 30 measures the distance between the moving image recording device 1 and the subject 1000, and when the subject 1000 is delayed, interrupts the movement of the moving image recording device 1 and performs a voice change or the like to encourage walking. May go. Further, the control circuit 30 may measure the walking distance and the traveling time of the subject 1000. Furthermore, the moving image recording apparatus 1 may include a laser pointer or the like, for example, and may have a function of marking a target point with the laser pointer or the like and guiding the target person.

  Further, the control circuit 30 may use the zoom function of the cameras 11 and 12 as a means for adjusting the camera position. More specifically, for example, in the moving image shooting in the “walking motion”, when shooting a motion in which the target person 1000 approaches or moves away from the device main body 2, the size of the target person 1000 on the shooting screen Varies depending on the distance to the cameras 11 and 12. For this reason, the control circuit 30 may adjust the size of the subject 1000 on the shooting screen using the zoom and focus adjustment functions of the cameras 11 and 12.

  When the moving image shooting ends, the control circuit 30 classifies the moving image data and the camera position information into the memory 31 by classifying the moving image data and the camera position information, for example, into the subject 1000 and the operation category (step S21).

1.3 Playback Mode Next, the playback mode 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. 9, for example, the user inputs the ID of the target person 1000 into the tablet PC 3 and logs in (step S30).

  When the reproduction mode is selected by the user (step S31), the control circuit 30 shifts to the reproduction mode.

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

  As shown in FIG. 10, for example, the playback moving image selection screen 130 is displayed on the display unit 10. For example, a patient number (subject identification number) and a patient name (subject name) are displayed in the upper row of the playback moving image selection screen 130. 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. 9, for example, one or two pieces of moving image data are selected by the user (step S32).

  When two moving images are selected, that is, when comparing the two moving images (step S33_YES), the control circuit 30 performs a moving image synchronization process (step S34). 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 1000 in the two moving images can be easily compared so that the movement timing of the target person 1000 is the same. Set. Note that the user may manually set the start point of the synchronized playback while watching the playback moving image.

  After the end of the synchronization processing in step S34, or when only one moving image has been selected and there is no moving image to be compared (step S33_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 S35).

  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 reproduction screens 140 and 141, seek bars for the respective image data are provided, and the current reproduction position 143 and the synchronous reproduction start position 144 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 past moving image data with the latest moving image data by synchronous reproduction, the user and the subject 1000 can easily confirm the recovery status of the subject 1000 due to rehabilitation.

  Note that, for example, the control circuit 30 may have a function of measuring the angle and length of the subject's joints (arms, legs, waist, neck, etc.) on the playback screen 140 or 141.

  Further, the control circuit 30 may have a function of superimposing and displaying two reproduction screens.

  Further, the control circuit 30 may have a function of correcting the size of the subject in the moving image data. More specifically, for example, a slight difference in size of the subject may occur between a plurality of pieces of moving image data. In such a case, the control circuit 30 may perform a size correction by comparing a fixed reference object such as the height of the subject, for example.

1.4 Effects According to the Present Embodiment With the configuration according to the present embodiment, the moving image recording apparatus can photograph the target person from the same camera position every time. Hereinafter, this effect will be described in detail.

  In order to check the daily recovery status of the target person due to rehabilitation, it is necessary to perform fixed point shooting at the same camera position (eg, distance between the target person and camera, camera height, camera angle, etc.) at each rehabilitation Is preferred. However, when the user installs the camera and the tripod every time the rehabilitation is performed, it is difficult to shoot at the same camera position as that at the time of the previous shooting. Further, the camera position differs for each subject depending on the content of the rehabilitation and the height of the subject. Therefore, it is difficult to reproduce the camera position for each subject.

  In contrast, the moving image recording apparatus according to the present embodiment can store the camera position at which the subject was previously photographed, and can automatically move to the stored camera position. Thus, the user can photograph the subject at the same position every time. Therefore, in the daily rehabilitation, the target person can be observed at a fixed point, and the recovery information of the target person by the rehabilitation can be easily confirmed.

  Furthermore, with the configuration according to the present embodiment, the moving image recording apparatus can automatically adjust the camera position. This eliminates the need for the user to set the camera.
