<θ- / q 2 / Reference number in the upper office number 1, description of the invention
Three-dimensional sound collecting device
3. Detailed description of the invention The invention relates to an apparatus for multiplexing
sound over video signals, and in particular to selectively process sound according to the
operation of a television camera. When playing back audio, it is possible to play back stereo
sound effects that fit the video. The audio accompanying the television image is usually one type,
but a second audio is added to give a stereo effect--even if it has two effects, the foreign language
of the foreigner's friend's language as this second audio. The experiment to broadcast the is at 1
in Tsuchi. That is, to the current television system! There are devices for transmitting and
broadcasting signals by adding two voices, and a device for receiving and transmitting effectively
two voices. However, after that, devices such as whistles will not be put to practical use at one
time, and depending on the television program content, if t with three-dimensional sound, it will
be extremely effective if it is extremely effective or if it becomes unnaturally negative. Because
there are FIG. 1 shows a commonly used method of broadcasting of video and audio, and shows
an audio obtained by one or a plurality of microphones il + and an image obtained by a television
camera (2) K. The current television broadcasting system (the NTSC system in Japan and the
United States of America) is K-compliant, or is recorded in a single-apparatus (hereinafter
abbreviated as VTR) + 311c with a signal format according to the present or broadcast . This
signal can be viewed on a monitor television (normal television EndPage: 1 receiver or

equivalent) (4). Here, although the operation lever (5) of the camera (2) and the camera optical
system (6) operate in conjunction with each other, it is customary that there is no interlocking
action with the audio system. The camera control device 1 # C (hereinafter referred to as CCU) is
a control device for adjusting the output signal of the camera tube η to a television signal form
such as the IJTSC method. As described above, in the case of a normal two-person broadcast
system, there is no linkage between shooting and operation of the camera and the audio system,
so the above-mentioned minus occurs. In the following, one embodiment of the tree blasting is
released based on FIG. 2 and the following drawings. In FIG. 2, a plurality of first-system
microphones (8) and a second-system microphone (9) are configured to pick up two types of
voices, and each voice such as a whistle can be amplified W 'foot' (at 11 and the voice control
unit (VTRQ3 capable of changing and amplifying the degree of change based on the command of
the country 1 and ratio etc. to two kinds of voice) K screen (or direct broadcast).
The reproduction signal of this VTR gang is two kinds of voice separated and amplified
respectively----"Seven pieces of time 52721209 (2), two or more speed"-Stereo sound
reproduction ship with television It can be reproduced and viewed on the receiver Q4. In case of
broadcasting by the second audio multiplex system and π, a television receiver having a circuit
fit for separating and amplifying the second audio multiplexed signal in addition to the
conventional television receiver on the receiver side shall be used . The features of the present
invention are stereo sound and L! In order to control the combination with one image, the voice
control unit (121 operates in conjunction with the camera lens control lever (5) and the camera
direction control lever (I5) to change the amplification factor of the amplification circuit (101H)
In order to balance, at least to form a change in the three-dimensional sound according to the
change in the image. The μ body side using a plurality of microphones is shown in FIG. In the
figure, 4 J +; 10 microphones (8) are used as the first microphone balance control device Q61,
and two microphones [1 phono group (9) as the second microphone balance control device 11
(each with Balance of the volume is performed, and the left and right volume, the balance of the
left and right volume in the three-dimensional sound balancer .theta. Now, by operating the
camera (2), the degree of the sum, which indicates the degree of the subject's up rate, is
calculated by the lever (In and (5+, the microphone balance control device 11 お and 3D) Sound
Balancer With the circuit configuration shown in FIG. 4, the adjustment of the three-dimensional
sound can be performed in conjunction with the 等 equal angle and the like. This is disintegrated
with FIG. 4 and FIG. In the figure, the microphones (9a) to (98) of the microphone group (9) on
the left side are arranged at KBm as in the example of the baseball stadium in FIG. 5, and the
microphones of the microphone group (8) are similarly arranged on the right. The lever (5I is
pushed to the right, and the volume of the microphones (9a) and (8fL) is larger than those of the
other (9b) to (9e) and (8'b) to (8e). When the up) such as the microphone (9e) (8'l) to hold the
weight of the voice compared to the other with a large weight, Mie-Kiiro Cloon balance control
11 p j, three-dimensional piece no ˜ Lancer in the middle of the volume of the volume · It is
possible to input and output a signal from the knob. The figure shows the lever in the state close

to the up (Z + showing 5 + stopped the addiction child, but in this case the microphone (96) (8 d)
n sound H also: l <, next ite (9 e) (8 e), The voices of the collected microphones are ordered in the
order of C (9 C) (8 C).
The left and right signals are output along mutually insulated sliders (l 曽 頒 1), and the voice J is
it QI cough 1 and the desired signal is sent to the load balancer (from 4 11241 to the output
terminal). L Force. The volume balancer 1231 e 24 i is interlocked with the directional multiple
lever (16) of the television camera (2), so that the output of the example volume balancer is
complementary, while the strength of the volume balancer is large so that one side becomes
smaller. The 2 ° audio adjustment device M (21, 2) balances both the angle θ and the
naturalness such as λ-conversion of the volume. In addition, camera + 2 + microphone, Landscontrol circuit! +6) 07) and on the inside of the three-dimensional sound balancer d8 · EndPage:
2-. As described above, according to the non-invention, when the zoom of the camera is over, or
when the angle is changed, the balance between left and right, the adjustment of the distant view
and the near view can be all made self-boarding, and the operation is simple. In addition, I have
recorded a front body voice corresponding to the screen of the main unit, can be idle transmitted,
can be effectively phantom, can be effectively added to each, the circuit system to do this is also
very m Facilitation ': This makes it possible to economically manifest.
