DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the apparatus according to the
present invention, by specifying the size of the image display by the input means, it is possible to
display an image of any size on the display as in the conventional apparatus.
Moreover, at this time, the sound associated with the image is adjusted to the volume according
to the display area of the image displayed on the display.
Therefore, if the image is displayed large on the display, the volume increases accordingly, and
conversely, if the image is displayed small, the volume decreases accordingly.
Therefore, the image and the sound are presented with a sense of unity.
[0015]
Further, when a plurality of images are displayed on the display, the sound associated with each
image is presented at a volume according to the display area of each image.
That is, the sound associated with the large displayed image is presented at a large volume, and
the sound associated with the small displayed image is presented at a small volume.
For this reason, even when a plurality of sets of presentation information consisting of an image
and a sound related to this are prepared and presented simultaneously, the image and the sound
are presented in a form in which the display area and the volume correspond to each other.
Therefore, individual presentation information is presented with a sense of unity.
[0016]
Further, in the device according to the present invention, the area to display the image can be
designated by the input means, and the image can be displayed on any designated area on the
display.
10-05-2019

Moreover, at this time, if a system using a plurality of speakers is used, a plurality of sound
images of sounds related to the image are generated at a position corresponding to the relative
position of the designated region with respect to the entire display region of the display. Since
sound can be presented from the speaker, it is possible to provide a sense of unity between the
position of the designated area and the position of the sound image.
[0017]
The present invention will now be described based on the illustrated embodiments.
FIG. 1 is a block diagram showing a basic configuration of an “apparatus for presenting an
image with sound” according to an embodiment of the present invention.
This apparatus comprises a data supply unit 100, a control unit 200, a display 300, a speaker
400, an input unit 500, and a reference volume setting unit 600.
The data supply means 100 is a means having a function of supplying presentation information
composed of image data and sound data, and in this embodiment, it is possible to present four
presentation information 10, 20, 30, 40. it can. Each presentation information 10, 20, 30, 40 has
image data 11, 21, 31, 41 and sound data 12, 22, 32, 42, respectively. These pieces of
presentation information 10 to 40 are supplied to the display 300 and the speaker 400 via the
control means 200. That is, the image data 11 to 41 is supplied to the display 300, and each
predetermined image is displayed on the display screen, and the sound data 12 to 42 is supplied
to the speaker 400, and each predetermined sound is the speaker. It will be emitted from
[0018]
The input unit 500 is a device for performing input for specifying the size of an image displayed
on the display 300. The control unit 200 performs a scaling process on the image data 11 to 41
supplied from the data supply unit 100 so that the image display is performed in the size
designated by the input unit 500, and the processed data is displayed It has a function given to
300. Further, in this embodiment, the input unit 500 has a function of inputting information on
10-05-2019
6
the display position of the image, and the control unit 200 performs image display based on the
size and position designated by the input unit 500. Control of the display 300.
[0019]
On the other hand, the reference sound volume setting unit 600 is a unit for setting a
predetermined reference sound volume. However, sound data supplied from the data supply
means 100 is not necessarily output from the speaker 400 at this reference volume. The control
means 200 has a function of performing volume adjustment processing on the supplied sound
data so that sound is generated at a volume according to the display area of the image displayed
on the display 300, and output from the speaker 400 The volume of the sound to be generated is
basically determined in accordance with the display area in which the image associated with the
sound is displayed on the display 300. However, when the entire image is displayed in a preset
reference size (in this embodiment, the maximum size), a sound is presented at the reference
volume set in the reference volume setting unit 600, Volume control processing is performed.
Therefore, by setting the reference sound volume setting unit 600, it is possible to determine the
reference sound volume (volume when the entire image is maximally displayed).
[0020]
The control means 200 can receive a plurality of sets of presentation information from the data
supply means 100 and can provide this to the display 300 and the speaker 400. Therefore, a
plurality of image data can be simultaneously displayed on the screen of the display 300, and a
plurality of sound data can be simultaneously output from the speaker 400. The input unit 500
can specify the size separately for each of the plurality of image data independently, and the
control unit 200 executes scaling processing on each image data, and The volume control
process is performed on the sound data corresponding to.
[0021]
The individual elements shown in FIG. 1 are actually configured by a system using a general
personal computer. That is, the control means 200 can be realized by incorporating
predetermined software in hardware including the CPU and memory of the computer, and the
display 300 and the speaker 400 are realized by a general display and speaker connected to the
computer. To be realized. Further, the input means 500 is realized by an input device such as a
10-05-2019
7
mouse or a keyboard connected to the computer, and the reference volume setting means 600 is
a volume control by hardware such as hardware control or software for controlling the speaker
400. It is realized by the function.
[0022]
On the other hand, various media can be used as the data supply means 100. That is, the image
data constituting the presentation information may be still image data or moving image data, or
may be any image data of a format that the control means 200 can handle. Similarly, the sound
data may be anything as long as the control means 200 can handle it. Therefore, the physical
configuration means of the data supply means 100 is not limited to a general computer
information recording device such as a hard disk device, a CD-ROM drive device, or an MO drive
device, but also a video reproduction device or an audio reproduction device. Alternatively, a
receiver such as TV broadcasting, cable broadcasting, satellite broadcasting may be used.
[0023]
Subsequently, the operation of this apparatus will be described while illustrating a specific image
displayed on the display screen 310 of the display 300. FIG. 2 (a) is a front view showing a
general form of a display screen 310 connected to a computer. A control area 311 is provided at
the top of the screen, and a command menu is displayed here. The operator can input various
commands by clicking the command displayed on the command menu in the control area 311
with a mouse or the like. A display area 312 provided below the control area 311 is an area for
actually displaying an image based on the image data supplied from the data supply unit 100. An
instruction indicating which image is to be displayed at which position and at which size can be
input by the mouse as the input unit 500. FIG. 2 (b) shows an example of presentation to the
presentation information 10. Here, based on the image data 11, a state in which the image 1A is
displayed in a predetermined window is shown. Now, the total area of the display area 312
shown in FIG. 2A is represented by a numerical value of 100% as the maximum display area, and
the display area of the image 1A shown in FIG. Let's say it was. In this case, a sound based on the
sound data 12 is output from the speaker 400 at a volume of 30% of the reference volume set in
the reference volume setting means 600 from the speaker 400.
[0024]
10-05-2019

The position and size of the window in which the image 1A is displayed can be arbitrarily
changed by the operation of the mouse as the input means 500. FIG. 3A shows a state in which
the image 1A is enlarged to the maximum display area 100% and the enlarged image 1B is
displayed, and FIG. 3B is a drawing in which the image 1A is reduced to the display area 10% A
state in which an image 1C is displayed is shown. As described above, it is a feature of the
present invention that when the display area of the image is changed, the volume is also
automatically changed accordingly. That is, in the display mode shown in FIG. 3A, the volume is
also increased to 100% (that is, the reference volume value in the reference volume setting
means 600), and in the display mode shown in FIG. It will be reduced to%. As described above,
when the sound volume is automatically changed according to the area of the display image, the
operator can feel a sense of unity between the image and the sound. Also, usually, when the
image is displayed large, it is considered that the operator has a greater interest in the image, so
automatically raising the volume is a volume according to the operator's intention. It is
considered to be an adjustment. Thus, the automatic volume adjustment according to the size of
the image is significant in that it improves the operability of the volume adjustment of the
operator.
[0025]
Such control can be easily performed by the control means 200. That is, based on an instruction
from the input unit 500, the control unit 200 takes in predetermined presentation information
(in this case, the presentation information 10) from the data supply unit 100, and first designates
the image data 11 Execute scaling processing based on the size. For example, if the image data
11 is raster image data, pixel interpolation may be performed to perform enlargement
processing, and pixel thinning may be performed to perform reduction processing. Then, the
display area when the image after the scaling process is displayed on the display 300 is
calculated. In the case of the example of FIG. 2 (b), a value of 30% is obtained with respect to the
maximum display area. Therefore, a process of giving a drive signal based on the sound data 12
to the speaker 400 may be performed so that the sound related to this image is output at a
volume of 30% of the reference volume set by the reference volume setting means 600. .
[0026]
FIG. 4 is a graph showing an example of the correlation between the display area S of the image
and the sound volume V. In this example, the relationship between them is a linear relationship V
= f1 (S), and the volume value Vr is the reference volume set in the reference volume setting
means 600. Changing the setting of the reference volume Vr will change the slope of this graph.
10-05-2019
9
However, the correlation between the display area S and the volume V does not necessarily have
to be a linear relationship as in the graph of FIG. 4. FIG. 5 shows an example in which the setting
of the non-linear relationship V = f2 (S) is performed. In this example, when the display area S
becomes 20% or less, the volume V becomes zero and no sound is output. Therefore, for example,
in the display mode as shown in FIG. 3 (b), no sound is output at all. With such a setting, it is
convenient to reduce the display when it is desired to only check the image without sound.
Further, even if the display area S becomes 100% or more, the volume V is saturated to the
reference volume Vr, and the volume does not increase any more. Therefore, for example, as
shown in FIG. 2A, even if the entire image is displayed in the largest size, the image is further
enlarged and only a part of the image is displayed on the screen. There is no increase in volume.
In this way, if the setting is made such that the volume never exceeds the reference volume Vr,
the volume can be prevented from becoming infinitely large, and a large volume is output
contrary to the operator's intention. It can be prevented.
[0027]
Thus, the correlation between the display area S and the volume V does not necessarily have to
be a linear relationship, but the relationship between the two is such that it becomes a
monotonically increasing function in which the volume V monotonously increases as the display
area S increases. It is preferable to set. If such a monotonically increasing function is set, then at
least the display area S is gradually increased, the volume V also increases accordingly, and never
decreases, so the operator's It becomes possible to adjust the volume suitable for the sense.
[0028]
Next, an operation in the case of presenting a plurality of presentation information
simultaneously will be described. Recent computers have a function of simultaneously launching
a plurality of software and simultaneously opening a plurality of files to simultaneously display a
plurality of windows on the same screen. For example, FIG. 6A shows a state in which the
presentation information 10 and the presentation information 20 are simultaneously presented.
In this example, the image 1D is displayed based on the image data 11 included in the
presentation information 10, and the image 2A is displayed based on the image data 21 included
in the presentation information 20. As described above, the position and size of the window for
displaying these images are specified by the input means 500 comprising a mouse. In this case,
sound data included in each piece of presentation information is output at a volume according to
the display area of each piece of image data. For example, assuming that the first image 1D is
displayed with a display area of 15% and the second image 2A is displayed with a display area of
10-05-2019
10
40%, a linear function V = f1 (S) as shown in FIG. 4 is set. In this case, the sound data 12
associated with the first image 1D is output at a volume of 15%, and the sound data 22
associated with the second image 2A is output at a volume of 40%, with the reference volume Vr
being 100%. It will be done. From the viewpoint of the operator, the sound associated with the
large image is presented large, and the sound associated with the small image is presented small,
so that the image and the sound are grasped with a sense of unity.
[0029]
In the case of displaying a plurality of windows, it is also generally performed to overlap and
display them. In such a case, it is preferable to obtain an actual display area not hidden by
another image, and to adjust the volume so that a related sound is generated at a volume
according to the actual display area. For example, in the state shown in FIG. 6A, it is assumed that
the first image 1D is enlarged and changed to an image 1E as shown in FIG. 6B. In this case, for
example, if the display area of the first image 1E is increased to 30%, the sound data 12 is also
increased to 30% and output. At this time, part of the second image 2A is hidden behind the first
image 1E, and if the actual display area is reduced to 10%, the sound data 22 is also reduced to
10% and output. It will be done. Thus, the volume control according to the actual display area of
the image is preferable because it matches the operator's intuition.
[0030]
The present invention is applicable not only to the case of presenting two pieces of presentation
information simultaneously but also to the case of presenting three or more pieces of
presentation information simultaneously. For example, FIG. 7A shows a state in which three
pieces of presentation information 10, 20 and 30 are presented simultaneously. In this example,
the first image 1F is displayed with an actual display area of 60%, the second image 2A is
displayed with an actual display area 8%, and the third image 3A is displayed with an actual
display area 5%. . Therefore, when the linear function V = f1 (S) as shown in FIG. 4 is set, the
sound data 12 associated with the first image 1F is output at a volume of 60% and associated
with the second image 2A. The sound data 22 is output at a volume of 8%, and the sound data 32
associated with the third image 3A is output at a volume of 5%.
[0031]
10-05-2019
11
However, when the number of pieces of presentation information is large as described above, a
large number of sound data are synthesized and output, and it becomes difficult to identify as a
whole. Therefore, in such a case, only sound data related to the screen with the largest display
area may be selectively presented. FIG. 7 (b) shows an example in which such selective sound
presentation is taken. 7 (b) is the same as FIG. 7 (a) with regard to image display, but with regard
to sound presentation, in FIG. 7 (b) only the sound associated with the first image 1F having the
largest display area is shown. Is output at 60% volume and no other sound is output (0% volume).
Similar effects can also be realized by devising how to define the correlation between the display
area S of the image and the sound volume V. For example, if the correlation as shown in FIG. 5 is
defined, the volume is 0% when the display area S is 20% or less, the display area is large even if
many images are displayed simultaneously. If the setting operation is performed so that only one
image exceeds 20%, only the sound related to this one image will be output.
[0032]
Subsequently, another embodiment of the present invention will be described. FIG. 8 is a block
diagram showing the basic configuration of the “apparatus for presenting an image with
sound” according to this another embodiment. The configuration of this device is almost the
same as the device shown in FIG. 1 except that it has a plurality of speakers. That is, the left
speaker 410 is provided on the left side of the display 300 and the right speaker 420 is provided
on the right side. As described above, when there are a plurality of speakers arranged so that
their relative positions with respect to the display 300 are different from each other, the volume
of each speaker is adjusted to generate a sound image corresponding to the display position of
the image. Then, it is possible to provide a sense of unity between the image and the sound. The
operation will be described in detail below.
[0033]
Similar to the apparatus shown in FIG. 1, also in the apparatus shown in FIG. 8, the input means
500 performs an input for specifying the size and display position for a specific image. Here, for
example, as shown in FIG. 9, it is assumed that the fourth image 4A is displayed on the display
screen 310 with a display area of 30%. In this case, in the apparatus shown in FIG. 1 described
above, the sound related to the image 4A is output from the speaker 400 at a volume of 30%.
However, in the apparatus shown in FIG. Sound is output from the left and right speakers 410
and 420 so that a sound image is generated. In the example of FIG. 9, since the image 4A is
displayed at a position slightly to the right of the display screen 310, the sound image of the
sound associated with the image 4A is also slightly to the right. Volume allocation will be made to
10-05-2019
12
increase the output.
[0034]
Let's show this more specifically. Here, the area in which the image display is performed based
on the designation from the input unit 500 will be referred to as a designated area. In the
example shown in FIG. 9, a rectangular area corresponding to the outline of the image 4A is
called a designated area. When the designated area for the image 4A is determined, the control
means 200 generates a predetermined audio signal based on the sound data 42 so that a sound
image corresponding to the relative position of the designated area to the entire display area of
the display screen 310 is generated. It has a function of supplying to the left speaker 410 and
the right speaker 420. In the example shown in FIG. 9, the center position M of the designated
area is 70% from the left and 30% from the right when the width of the entire display area is
100%. Therefore, in the apparatus of this embodiment, the total volume of 30% (corresponding to
the display area of the image 4A) is divided by the inverse ratio of 70%: 30% to determine the
volume of the left and right speakers 410 and 420. That is, the volume of the left speaker 410 is
30% × 30% = 9%, and the volume of the right speaker 420 is 30% × 70% = 21%. The total
volume of both speakers is 9% + 21% = 30%, corresponding to the display area of image 4A, but
the balance on the left and right is inclined to the right, and the sound image is slightly shifted to
the right .
[0035]
Here, for example, as shown in FIG. 10, it is assumed that the size and the display position of the
image 4A are changed, and the image 4B is displayed with a display area of 60%. %, Assuming
that it is 60% from the right. In this case, the volume of the left speaker 410 is 60% × 60% =
36%, and the volume of the right speaker 420 is 60% × 40% = 24%. The total volume of both
speakers is 36% + 24% = 60%, corresponding to the display area of image 4B, but the balance on
the left and right is inclined to the left, and the sound image is slightly shifted to the left .
[0036]
In the above example, the left and right balance of the center position M of the designated area
and the volume balance of the left and right speakers are simply linearly associated, but the two
do not necessarily have to be linearly associated, and the left and right of the image display
10-05-2019
13
position Any correspondence relationship may be defined as long as the viewer can recognize
that the balance of and the left and right balance of the sound image position are associated with
each other. In the above-described example, only the single presentation information 40 is
presented. However, when a plurality of presentation information are presented simultaneously,
the central position M of the designated area is determined for each image. Synthesized sounds
based on a plurality of supplied sound data may be output from the individual speakers so that
sounds associated with the individual images produce a sound image corresponding to the center
position M determined for each image. . Furthermore, in the above-mentioned example, although
two speakers are installed on the left and right of the display 300, when two speakers are
installed on the upper and lower sides of the display 300, the balance of the display position of
the image and the sound image position It is sufficient that the balance of the upper and lower
sides of the is associated with each other. Of course, the present invention is also applicable to
the case where four speakers are installed at the top, bottom, left, and right, or when more
speakers are installed. In short, the basic concept of the present invention is to When a plurality
of speakers are installed, a plurality of speakers produce a sound image according to the display
position of the image, and it may be implemented in any manner without departing from this
basic idea. .
[0037]
As mentioned above, although the present invention was explained based on the example
illustrated, the present invention is not limited to these examples, and can be carried out in other
various modes besides this. For example, in the above-described embodiment, although the
present invention is applied to a multimedia reproduction system using a personal computer, the
present invention is also applicable to a general TV receiver. Currently, there are commercially
available TV receivers having a function to display so-called back programs small on the same
screen, but if the present invention is applied to such a TV receiver, a large volume is output for
the main program. For a back program displayed on a small screen, it is possible to output a
small volume, and according to the display position of the screen, it is possible to provide sound
with a predetermined volume balance from the left and right speakers. Recently, personal
computers that can receive TV broadcasts and display programs have also begun to spread, but if
the present invention is applied, for example, when receiving a news program, viewing at a small
volume with a small window display When receiving a movie program, it can be easily used
properly, such as viewing at a large volume and displaying a large window.

The present invention is also applicable to a display device in which a large number of light
emitting elements (such as light bulbs and LEDs) are arrayed, such as electric bulletin boards and
advertisement boards provided on the streets. In such a display device, the power consumption is
largely influenced by the display area of the image, and a large image or a small image is
displayed in an irregular manner. Therefore, if the present invention is applied to present a
sound, a sound and an image can be presented with a sense of unity. In short, the present
invention is applicable to any device as long as it is a "device that presents an image with sound".
[0039]
As described above, according to the present invention, the sound is presented at a volume
according to the display area of the image, and a sound image according to the display position
of the image is generated. It becomes possible to give a bodily sensation.
