DESCRIPTION JP2001298733
[0001]
FIELD OF THE INVENTION The present invention relates to photography, projection and sound.
[0002]
[0002] Televisions and photographs are commonly used as reproduction machines. The practical
reproduction machine was easy to use and sufficient for practical use.
[0003]
However, the scene is determined by the photographer's intention, and the viewer has the
disadvantage of only looking at it.
[0004]
In general applications, this drawback is an obstacle.
Specifically, there was a problem such as not being able to see one's favorite scene.

[0005]
As measures to remedy this, there are multi-channel broadcasts and multi-scene shooting, but
this leads to an increase in cost.
[0006]
[Problems to be Solved by the Invention] The problem to be solved is that the user can not easily
view the favorite scene in full view.
[0007]
[Means for Solving the Problems] The present invention is characterized in that all celestial
spheres and all celestial scenes are sent, and the receiving side is viewed at a favorite angle of
view.
The sound is also reproduced realistically according to the image.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION An image and a sound full of human vision
are realized with a minimum number of parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 is a view showing the
construction of an embodiment of the present invention apparatus, in which a hemispherical
bulb with a wide-angle lens such as a fisheye lens 1 or a whole spherical bulb with a single
fisheye lens 1a is planarized. Convert it and shoot it directly with camera 2 or 2a, send it directly
or record it with a projector 3 or 3a and project it onto a screen 5 through a wide-angle lens such
as a fisheye lens 4 or 4a, and give a sense of presence with a focusing and magnifying lens 8 It is
viewed in full view.
Of course you may project on the wall of the room.

The shooting angle may be changed according to the application. The screen 5 may be either
inside or outside, or may be flat. When viewed from the back side of the screen 5, the projection
plane is reversed so as to be opposite to the left and right in shooting. The observer operates the
projector 3 or 3a, the lens 4 or 4a with the left and right rotary machine 6a, the vertical rotary
machine 6b, and the diagonal rotary machine 6c using the corresponding sensors or remote
controllers 7a, 7b, 7c. The scene of the angle of view can be selectively projected on the screen 5.
The screen may be moved up and down as shown in the figure. Depending on the application, the
number of rotating machines may be reduced so that only the left and right rotating machines 6a
are sufficient if only around the circumference. Also, the image captured on the screen 5 may be
captured by the camera 9a from the opposite side or from the same side by 9b and projected by
the projector 10 onto the remote screen 5a or may be viewed directly from the display panel
10a. The screen 5 is translucent on the opposite side and reflective on the same side. The
rotating machine includes a motor, a stepping motor, a controller as a controller, a pulse
generator, and the like. Both include torque syncs and so on. The motor should have a brake lock.
Sound collected or recorded by at least five outwardly directed microphones 11a, 11b, 11c, 11d,
and sterically disposed, and at least five inwardly directed speakers 12a, 12b, sterically disposed.
Sounds are produced at 12c, 12d and 12e, and two movable microphones 14a and 14b are
arranged at both ends of a movable arm at the central portion thereof, collected and heard by
stereo headphones 15a and 15b. If only around the periphery is sufficient, at least three of each
of 11a, 11b, 11c, 12a, 12b, 12c arranged at least in a plane are sufficient. At this time, the left
and right 13a, upper and lower 13b, and oblique 13c rotating machines are operated by the
operating devices 7a, 7b and 7c so as to be interlocked with the image. It is desirable that the
microphone 11 and the speaker 12 be nondirectional, and the microphone 13 be similar to the
directivity of the human ear. FIG. 2 is an enlarged view of the photographing section, and the
light passing through the lens 1 or 1a is bent by the mirror 16 or 16a, and a single lens 17 is
used to pick up an imaging surface 18 such as a television or video camera or a film surface such
as a slide. It is imaged. The lens 17 may be divided into two pieces 17a and 17b so that it can be
adjusted more precisely. FIG. 3 shows the use of a conical mirror 19 or a half curved mirror 20 in
place of the lens 1 of FIG. FIG. 4 is an enlarged view of the projection part and is structurally the
same as FIG. The image emitted from the display surface 22 such as a liquid crystal screen, a film
surface or the like is adjusted by the lens 21 or 21a, 21b so as to be best reflected on the screen
5.
There are two types of display surfaces: transmissive, reflective and luminescent. 23 is a light
source. FIG. 5 shows an angle-of-field adjustment unit of the projection unit, and FIG. 4 shows a
bracket that freely supports and rotates left, right, up, down, and diagonally the one in FIG. The
shaft of the oblique rotating machine 6c is connected and fixed to the center of the unit 24a, and
the outer frame of the unit 6c is fixed to the support 24c of the apparatus. The left and right
rotating machine 6a is fixed at the center of the shaft 24b, and its rotation axis is connected and
fixed to the projection unit of FIG. The rotary shaft of 6b of the vertical rotating machine is
10-05-2019

connected to 24b at the connection part of 24a and 24b, and the outer frame is connected to
24a. FIG. 6 shows the actual mounting of FIG. FIG. 7 shows a case in which the reflecting mirror
19 is mounted, and only the left and right rotating machine 6a is used, and the light shielding
plate 25 is installed at the back so that light does not leak unnecessarily. In the case of sitting
straight as the reference angle of the sensor, take the ceiling or floor in the case of left and right
7a, horizontal 7b on the wall, and diagonal 7c on the wall perpendicular to the wall of 7b. FIG. 8
shows a rotating machine and an operation unit using a Hoiston's Blich in a wired servo system,
and it is easy to bend the rotation shaft 27a of the variable resistors of the sensors 7a, 7b and 7c
attached to the head, and twists A rigid piano wire 27b is fixedly connected, and the other is
fixed to the floor or ceiling in the case of the left and right rotary machine, and to the wall in the
case of the vertical and horizontal rotary machine. The value of the variable resistor 26a changes
according to the movement of the head, and the angle-of-view change motor 6a or 6b or 6c
rotates and follows. If it is troublesome to move the head, the switch 27c may be switched to the
near side to operate the variable resistor 26b. In wireless communication, a gyro may be attached
to the rotation shaft 27a. FIG. 9 is intended to capture and reproduce three-dimensionally, and
the lens 1, 1a of FIG. 2 or the reflecting mirror 19 of FIG. The image is reproduced on the display
surface 23, photographed with the camera 9a for the right eye and the left eye, and two sets of
the apparatus of FIG. 5 are installed and projected on the dedicated screens 5b and 5c. If it is one
imaging surface 18, a commercially available camera can be diverted. A light shielding plate 25
may be provided so that the image for the left eye is not projected on the screen for the right eye.
In the case of a planar image, the left and right same screen is displayed by the changeover
switch 27e. Of course, the projection unit is rotated by the movement of the sensors 7a, 7b, 7c. In
addition, although it is possible to use two imaging planes by photographing with two cameras, it
is complicated and expensive. FIG. 10 shows that the other imaging unit does not block the field
of view during stereoscopic imaging. The rotational movement of the motor 28 is changed to
reciprocating movement, and the lenses 1 and 1a attached to the L-shaped arms 29a and 29b are
fulcrum 29c. The lens which is moved to an unobstructed position with the center at the center
and opened is focused on the imaging surface 18.
Alternatively, the light shielding plates 25a and 25b may be inserted between the mirrors 16 and
16a and the imaging surface 18 to shield the image. In this way, a single imaging surface 18
simplifies the mechanism. FIG. 11 shows stereoscopic imaging using a conical mirror 19 or 20,
which is vertically moved to an unobstructed position so that only the image which is lowered is
imaged, and also one imaging surface 18 is used. FIG. 12 shows a mechanical scanning type that
electronically changes the angle of view, and an image is put on the imaging element surface 30
through the lens 17 and rotated at high speed by the motor 29 to form the scanning line 31. If
you take 30 pictures per second, it is 1800 revolutions per minute. You may attach the balancer
33 so that it may rotate smoothly. The elements of the vertical and horizontal deflection circuits
that change the cutoff voltage of the amplifier tube to which the sawtooth wave and the square
wave are applied are adjusted from the reference point 0 to t1 and t2 by the sensors 6a and 6b,

and the display surface at an arbitrary angle of view It is displayed on 32. FIG. 13 is an electronic
reproduction of sound not mechanical but the sound input from the microphones 1, 2, 3, 4 and 5
is divided into left and right ears and the microphone 35 is shown in FIG. When arranged, the
gain is adjusted to obtain the characteristics shown in FIG. 14, mixed in the mixer 37, and heard
by the speaker 15a of the stereo head. 36a is a gain regulator. FIG. 14 shows the relationship
between the directivity of the microphone for the left ear, the directivity of the speaker, and the
position, and the directivity is expressed in solid polar coordinates. Take the dynamic angle in the
direction of the arrow, turn the arm to θx horizontal, raise it on θy, and raise the microphone to
θmy, and the directional radius of the speaker is s1 = ρ1 (θ11, θ12), s2 = ρ2 (θ21, θ22) ),
S3 = ρ3 (θ31, θ32), s4 = ρ4 (θ41, θ42), s5 = ρ5 (θ51, θ52), microphone m1 = ρm1
(θm11, θm12), m2 = ρm2 (θm21, θm22), m3 = ρm3 (θm31, θm32), m4 = mm4 (θm41,
θm42), m5 = 5m5 (θm51, θm52), distance to the microphone L11, L21, L31 (L11 / L11)
squared × s1 × m1. The magnitude of the sound is inversely proportional to the square of the
distance. The amplifier gain of the second speaker is (L11 / L21) squared × s2 × m2, the gain
of the third speaker amplifier is (L11 / L31) squared × s3 × m3, the amplifier gain of the fourth
speaker is The gain of the amplifier of the (L11 / L41) squared × s4 × m4 and fifth speaker
may be adjusted to be (L11 / L52) squared × s5 × m5.
The amplifier for the right ear may be the same. At the end of the arrow, we show how to take
the angle and the structure of the microphone, arm and rotating machine.
[0010]
As described above, according to the panoramic reproduction apparatus of the present invention,
it is possible to enjoy a realistic, realistic image and sound at a desired viewing angle.
