  In the exercise school described above, there is a problem that students need to go to school and are troublesome. In addition, although it is conceivable to acquire exercise techniques using videos and DVD teaching materials, there is a problem that the technique is monotonous and often does not last long.

  The present invention has been made to solve such a problem, and an object thereof is to provide an exercise video transmission device and an exercise video photographing device capable of transferring effective exercise technology.

  In order to achieve the above object, according to one aspect of the present invention, the exercise video transmission device receives a selection request from a video distribution server that stores videos of a plurality of types of exercises and a personal computer of the student, Based on the exercise video stored in the video distribution server on the personal computer, the transmission means for transmitting the desired video of the student, and the exercise video connected to the personal computer of the student and transmitted by the transmission means And a 3D image display for reproducing exercise 3D images.

  Preferably, the student's personal computer is connected to a display that performs two-dimensional display instead of the stereoscopic video display, and reproduces the exercise two-dimensional video based on the exercise video transmitted by the transmission means.

  According to another aspect of the present invention, an exercise video photographing device includes a camera for photographing an exercise instructor, and surrounds the circumference of the exercise instructor, and the video of the exercise instructor viewed from a plurality of different directions is described above. A mirror that reflects toward the camera, and the camera captures images of the exercise instructor reflected from the mirror as seen from a plurality of different directions.

  According to these inventions, it is possible to provide an exercise video transmission device and an exercise video photographing device capable of transferring effective exercise technology.

  FIG. 1 is a diagram showing a configuration of an exercise video transmission device according to one embodiment of the present invention.

  Referring to the figure, the exercise video transmission device is connected to the Internet 105, a transmission video creation PC (personal computer) 103 connected to the Internet 105, a plurality of cameras 101 a, 101 b,. The video distribution server 107 stores videos of a plurality of types of exercises, a student (user) PC 109 connected to the Internet 105, and a stereoscopic video display 111 connected to the student PC 109.

  The plurality of cameras 101a, 101b,... Is a camera for photographing a 3D image when an exercise instructor (a subject who is a trainer) performs an exercise exercise in a shooting studio. For example, when taking an image from 360 ° around the front, back, left side, and right side of the subject, the plurality of cameras 101a, 101b,... Are arranged so as to surround the subject. In addition, when taking an image from above or below the subject, a camera for photographing the subject from above or below may be included.

  Further, for example, if a single camera can capture images from a plurality of directions of a subject by using a mirror, the number of cameras used can be reduced. For example, a subject is surrounded by a plurality of mirrors installed at different angles, and a plurality of subject images viewed from different angles reflected on the mirror are photographed with one camera, so that one frame image of one camera is plural. A subject image viewed from a direction can be included. In this case, one camera is sufficient.

  For example, in a dance studio, it is conceivable to surround 360 ° around the subject with N (N> 1) mirrors. Install each mirror at an angle so that the reflecting surface of each mirror faces slightly upward. If images from N mirrors are taken with one camera provided on the ceiling, an image viewed from the N direction around the subject can be taken with one camera. Further, N synchronized images can be obtained simultaneously in one image frame.

  The video is stored in the video distribution server 107 and transmitted to the student PC 109 as necessary.

  The stereoscopic video display 111 is a display for reproducing a subject image viewed from a plurality of directions as a three-dimensional video.

  For example, the stereoscopic video display 111 includes one or a plurality of projectors for projecting each of subject images viewed from a plurality of directions, and a projection medium that projects light from the projectors. As a projection medium, a mirror (plane mirror, curved mirror) whose vertical axis is rotated at high speed by a motor, a plane screen which rotates the vertical axis, a curved screen, a polyhedral screen, a half mirror, fine particles such as smoke, and the like are used. Can do.

  For example, in the above-described case where the subject is surrounded by a plurality of mirrors and images from the plurality of mirrors are shot with a single camera provided on the ceiling, the stereoscopic image display 111 uses a projection medium. Surrounding with a plurality of similar mirrors, if the image obtained by the one camera is projected from the top onto the mirror by the projector, and the image is projected onto the photographing medium through the mirror, Dimensional images are easily reproduced.

  Furthermore, as the stereoscopic image display 111, a display that uses polarized glasses or liquid crystal shutters and that changes the image incident on the left and right eyes of the student may be employed.

  Further, even when the stereoscopic video display 111 is not connected to the student PC 109, the video can be reproduced on the display (personal computer monitor) that performs the two-dimensional display of the student PC 109.

  In this case, one or a plurality of videos in which the subject is viewed from a plurality of directions are displayed on one screen. The video to be displayed is different depending on the instruction from the user. For example, in the initial state, an image taken from the front of the instructor is displayed on the two-dimensional display, and the angle of the instructor that is gradually displayed is changed according to the user pressing the cursor key.

  Further, the system is configured so that a part of the 3D and 2D video can be enlarged or reduced according to an instruction from the user.

  FIG. 2 is a flowchart showing processing executed by the exercise video transmission device.

  Referring to the figure, when access is made from student (user) PC 109 to server 107 in step S101, server 107 causes student PC 109 to display a user ID and password input screen in step S103. The user logs in by entering the user ID and password on the screen.

  In step S105, the server 107 displays an exercise category selection screen on the student PC 109, and the student selects a desired exercise category. For example, this allows the student to select the type of exercise from the main menu of exercises such as dance, yoga, stretching, sports, and care methods.

  If a selection has been made, a lower selection is made in step S107. For example, if “Dance” is selected, lower-level menus such as hip-hop, jazz, and ballroom dance are selected. If “Sports” is selected, lower-level menus such as tennis and golf are selected. It is.

  In step S109, the three-dimensional video data corresponding to the selection is transmitted from the server 107 to the student PC 109. In step S111, the student PC 109 and the stereoscopic video display 111 reproduce the video.

  3 and 4 are flowcharts showing the content of the video reproduction (S111) in FIG.

  Referring to the figure, it is determined in step S201 whether or not a three-dimensional video can be reproduced. If the 3D image can be reproduced, the 3D image is reproduced on the stereoscopic image display 111 in step S203.

  In step S205, it is determined whether the reproduction has ended. If YES, this routine is ended.

  If NO in step S205, it is determined in step S207 whether there has been a user input such as fast forward, rewind, slow playback, image enlargement, etc., if NO, playback continues in step S203, and if YES, in step S209. After executing the process corresponding to the user input, the reproduction is continued in step S203.

  If it is determined in step S201 that the 3D video cannot be reproduced, the 2D video is reproduced in step S301 (FIG. 4). At the start of playback, an image capturing the front of the instructor shall be displayed.

  In step S303, it is determined whether the reproduction is completed. If YES, this routine is terminated.

  If NO in step S303, it is determined in step S305 whether there has been a user input such as fast forward, rewind, or slow playback. If NO, playback continues in step S301. If YES, user input is entered in step S307. Perform the corresponding process.

  In step S309, it is determined whether there has been an input for changing the viewing angle of the instructor from the user or an input for changing the display size. If NO, playback continues in step S301, and if YES, user input is entered in step S311. After executing the corresponding process, the reproduction is continued in step S301.
