Description

  The present invention relates to an integrated karaoke apparatus used in a banquet hall or the like.

  Conventionally, an integrated karaoke apparatus used in a banquet hall or the like is known (for example, see Patent Document 1). This type of karaoke apparatus is configured such that an apparatus main body, an amplifier, a speaker, a display, and the like are housed in a teacher-type casing and equipped with casters for simple movement and installation. At the time of use, this integrated karaoke apparatus is installed in a banquet hall or the like, and a singer performs a song to a large audience as a simple “stage”. The main demand is the reception hall.

  A problem with such an integrated karaoke device for a banquet hall is that the singer's line of sight faces the display. In other words, the singer tends to look down at the lyrics telop of the karaoke apparatus with his eyes, so the singer tends not to give a positive impression to the audience as an attitude of singing on the stage such as a reception. Moreover, the karaoke apparatus itself may block the line of sight from the audience to the singer and hide the singer's face. This also causes a negative impression to the audience. Another problem is the availability factor of the integrated karaoke apparatus for the banquet hall. In other words, the use of karaoke equipment at the banquet hall as described above is mainly limited to the time during which the banquet is held, mainly from the evening to the night. There is a problem that cost efficiency is often undesirable.

On the other hand, the usage form of a karaoke device called a so-called karaoke box is mainly called day karaoke, and there is much commercial demand during the day. Therefore, as one proposal, there is a demand for a karaoke apparatus that can satisfy the demand for both use in a karaoke box and use in a banquet hall.
Japanese Patent Laid-Open No. 10-20868 Japanese Patent Laid-Open No. 08-87283

  By the way, when using the karaoke apparatus as described above in a banquet hall, the karaoke apparatus is installed in a banquet hall or the like as described above, and a singer faces a large audience as a simple “stage”. In order to perform a song, the singer and the audience face each other across the karaoke device, and the audience sees the singer's singing, facial expression, posture, etc. from the front.

  However, if the singer does not fully remember the lyrics, he follows the lyrics telop displayed on the display, so the singer's line of sight may turn downward or move unsteadily. There was a problem that it became a facial expression and posture, that is, a singer who would not want to be seen by the audience.

  In addition, as in Patent Document 2, a singer looks at the direction of the audience by using a head-up display such as a half mirror for the lyric screen display section and forming a lyric screen as a virtual image behind the head-up display. A karaoke system that allows you to sing and see the lyrics at the same time has also been proposed, but if the singer does not fully remember the lyrics, it will change to follow the lyrics telop displayed as a virtual image. However, it is assumed that the same problem occurs.

  The present invention has been made in view of such problems, and the object of the present invention is to sing when an integrated karaoke apparatus used in both a karaoke box and a banquet hall is used in a banquet hall. Even when the person is in a positional relationship with the audience, the singing of the singer as viewed from the audience side, particularly the face and line of sight, is to be able to perform karaoke singing so that it can be seen in its natural appearance.

  The karaoke apparatus according to claim 1, which has been made to solve the above-described problem, is selected from a housing, a display that is attached to an upper portion of the casing and has a substantially planar display area capable of displaying various images. A karaoke apparatus comprising a control means for performing karaoke performance on a karaoke piece and displaying an image composed of lyrics telop or background video on the display, and further, visible light formed on a plate and irradiated on one surface A first display state in which the display area is directed to the front side of the karaoke device, and the display The posture can be changed with the second display state in which the region is directed to the half mirror disposed above the housing, and the half mirror is When arranged above the housing, the image displayed in the display area of the display in the second display state is reflected toward the rear of the karaoke device, and the half mirror is above the housing. And an image reversing means for horizontally reversing the image displayed in the display area of the display.

  According to the karaoke apparatus of the present invention configured as described above, the following operational effects can be obtained. That is, when the display is in the first display state, by directing the display area to the front of the karaoke device, a singer who performs karaoke singing in front of the karaoke device and a viewer who appreciates the karaoke song of the singer Display an image. Moreover, when a half mirror is arrange | positioned above a housing, the image displayed on the display area of the display in a 2nd display state is reflected toward the back of the said karaoke apparatus. Further, when the half mirror is arranged above the housing in this way, the image reversing means reverses the image displayed in the display area of the display left and right. In this case, the singer behind the karaoke device and the viewer ahead of the karaoke device can see each other through the half mirror. As a result, the singer who performs karaoke singing behind the karaoke apparatus is less likely to move when looking at the image displayed in the display area of the display in the second display state, and the singer's eyes are stabilized. In addition, the face of the singer as seen from the viewer (audience) is not hidden. Therefore, when the karaoke apparatus is used in the banquet hall, the singer can perform karaoke singing in a natural appearance even if the karaoke apparatus is in a positional relationship facing the audience.

  In this case, as in claim 2, when the half mirror is arranged above the housing, it is considered that the half mirror is positioned above the display area of the display in the first display state. If comprised in this way, the singer who sees the image reflected in a half mirror can keep the eyes high compared with the case where the singer who sees the image reflected in the display area of the display in the first display state. Therefore, the singer can perform karaoke singing with a more natural appearance.

In addition, about the above-mentioned half mirror, it is possible to attach to the upper part of a housing via a hinge. If comprised in this way, there is no possibility of losing a half mirror.
However, when the half mirror is attached to the upper part of the housing via a hinge in this way, the half mirror may enter the field of view of the singer or the viewer, which may hinder the concentration on karaoke singing or viewing. Therefore, as described in claim 3, it is conceivable that the above-described half mirror can be attached to and detached from the upper portion of the housing. If comprised in this way, when not in use, by removing the half mirror, it is possible to concentrate on karaoke singing and appreciation without entering the field of view of the singer or appreciator. In addition, when the singer concentrates on karaoke singing in this manner, the line of sight of the display area of the singer's display becomes difficult to move, and the singer's line of sight is stabilized. Therefore, when the karaoke apparatus is used in the banquet hall, the singer can perform karaoke singing in a natural appearance even if the karaoke apparatus is in a positional relationship facing the audience.

  By the way, when the display state of the display changes as described above, if the display mode of the image on the display is left as it is, the display state of the display and the display mode of the image on the display do not match, and the singer's display The line of sight of the display area may be easy to move. For example, when a karaoke device is used in a karaoke box, the singer and the viewer often see the display from the same direction, so the lyrics telop and background video are displayed in the display area of the display in the first display state. However, when using a karaoke device in a banquet hall, the singers and viewers are in a positional relationship facing each other across the karaoke device, so for singers who want to concentrate on karaoke singing Displays only the lyrics telop, and it is preferable to display the background video as well as the lyrics telop for viewers who want to enjoy not only the state of the singer but also the lyrics as well as the background video. And the display mode of the image on the display, the line of sight of the singer's display area is less likely to move Monitor, because also it is possible to enjoy the place for the viewer.

  Therefore, it is conceivable to change the display mode of the image on the display according to the display state of the display. Specifically, as in claim 4, there is provided display state detecting means for detecting the display state of the display, and the control means displays the display area of the display according to the display state of the display detected by the display state detecting means. It is conceivable to change the display mode.

  If comprised in this way, the line of sight which looks at the display area of a singer's display will become difficult to move, and a singer's eyes will be stabilized. Therefore, when the karaoke apparatus is used in the banquet hall, the singer can perform karaoke singing in a natural appearance even if the karaoke apparatus is in a positional relationship facing the audience.

As specific examples of the method for changing the display mode of the image on the display in accordance with the display state of the display, for example, the following (A) to (D) are conceivable.
(A) First, when the display state of the display is switched, it is conceivable that the image being displayed on the display is reversed left and right. Specifically, as described in claim 5, when it is determined that the display state of the display has been switched based on the detection result by the display state detection unit, the control unit displays the video being displayed in the display area of the display. The opposite is conceivable. In this case, the control unit functions as an image inversion unit. If comprised in this way, while the function of the above-mentioned image inversion means can be performed automatically, the eyes | visual_axis which sees the display area | region of a singer's display become difficult to move, and a singer's eyes | visual_axis is stabilized. Moreover, even if the singer does not remember the lyrics accurately, it is possible to perform karaoke singing with a natural feeling.

  (B) In addition, when using a karaoke device in a banquet hall, when the background image is displayed in the display area when the display is in the second display state, the singer's eyes react to the change in the background image, The singer's line of sight is easy to move up, down, left and right, and the singer's singing appearance through the half mirror looks unnatural when viewed from the viewer (commonly known as: eyes are swimming), so the display is the second display When in the state, it is conceivable that the background video is erased and only the lyrics telop is displayed in the display area of the display. Specifically, as described in claim 6, when it is determined that the display is in the first display state based on the detection result by the display state detection unit, the control unit includes the lyrics telop and the background in the display area of the display. When an image composed of video is displayed and the display is determined to be in the second display state, the control means displays an image composed of the lyrics telop in the first display state and the background video in the display area of the display. It is conceivable to display an image from which the background video has been deleted. If comprised in this way, the line of sight which looks at the display area of a singer's display will become difficult to move, and a singer's eyes will be stabilized. Moreover, even if the singer does not remember the lyrics accurately, it is possible to perform karaoke singing with a natural feeling.

  (C) When the lyrics telop is displayed in the display area of the display when the display is in the second display state, such as when the karaoke apparatus is used in a banquet hall, the eyes of the singer who follows the lyrics telop in accordance with the karaoke performance When the display is in the second display state, the singing of the singer through the half mirror looks unnatural (known as the eyes are swimming). It may be possible to fix the color change point, which is the point, and scroll the lyrics telop in the horizontal direction. Specifically, as in claim 7, when it is determined that the display is in the second display state based on the detection result by the display state detection unit, the control unit displays the lyrics being displayed in the display area of the display. Change the color of the lyrics telop at the lyric position to be sung in the telop, and change the position of the lyric telop displayed in the display area to the left and right according to the karaoke performance without changing the color position even if the karaoke performance progresses. It is possible to scroll. If comprised in this way, the line of sight which looks at the display area of a singer's display will become difficult to move, and a singer's eyes will be stabilized. Moreover, even if the singer does not remember the lyrics accurately, it is possible to perform karaoke singing with a natural feeling.

  (D) Also, as shown in (c) above, in order to display the lyrics telop in the display area of the display when the display is in the first display state, such as when the karaoke device is used in a karaoke box, It is conceivable to change the display color in order according to the karaoke performance. Specifically, as in claim 8, when the display unit determines that the display is in the first display state based on the detection result by the display state detection unit, the control unit displays the lyrics being displayed in the display area of the display. It is conceivable to change the display color of the telop in order according to the karaoke performance. If comprised in this way, when using a karaoke apparatus with a karaoke box etc., even if a singer does not remember the lyrics correctly, karaoke singing can be performed with a natural feeling.

[Description of karaoke music performance processing]
Below, the process sequence of the karaoke music performance process which karaoke apparatus 1CPU14 performs is demonstrated based on FIG. This karaoke music performance process is a process that is started when the power of the karaoke apparatus 1 is turned on.

  When the karaoke music performance processing is started, first, it is determined whether or not the state of the half mirror attachment state detection switch is OFF (S110), and the operation mode is determined according to the state of the half mirror attachment state detection switch. Is determined (S120). Specifically, when the state of the half mirror attachment state detection switch is OFF (S110: YES), it is determined that the half mirror 29 is not attached to the housing 100a, and the operation mode of the display 24 is displayed. 1 (karaoke box mode) is determined. On the other hand, when the state of the half mirror attachment state detection switch is on instead of off (S110: NO), it is determined that the half mirror 29 is attached to the housing 100a, and the operation mode of the display 24 is displayed. 2 (banquet mode) is determined. The determined operation mode type is stored in the DRAM 25 (S130). When the execution of S110 is performed for the second time or later, the operation mode is switched when the state of the half mirror attachment state detection switch 28 changes.

  Subsequently, referring to the stored contents of the DRAM 25, it is determined whether or not the operation mode is the display state 1 (S140). When it is determined that the operation mode is the display state 1 (S140: YES), the video inversion circuit 26 is set to OFF (S150), while the operation mode is not the display state 1 but the display state 2. If it is determined (S140: NO), the video inversion circuit 26 is turned on (S160), and the process proceeds to S170.

  Then, it waits until a music selection input is made from the operation panel 10 (S170). When a music selection input is made from the operation panel 10, the music data of the selected karaoke music is read from the music data database of the HDD 13 ( S180), karaoke performance is started based on the read music data (S190). This karaoke performance process is composed of three tasks: (a) a performance task (S200 to S220), (b) a telop display task (S230 to S270), and (c) a background video output task (S280 to S310). These three tasks are processed in parallel. Hereinafter, it demonstrates in order.

(A) Performance task (S200 to S220)
The performance task is a task for performing karaoke performance based on the MIDI data included in the song data. First, a performance task is started (S200), and MIDI performance processing is executed based on the MIDI data included in the song data (S210). Note that “MIDI-telop synchronization data” for synchronizing the MIDI performance and the display of the lyrics telop is sequentially generated and stored in the DRAM 25. When the MIDI performance process based on the MIDI data is completed, the performance task is terminated.

(B) Telop display task (S230 to S270)
The telop display task is a task for displaying the lyrics telop data included in the song data on the display 24 in accordance with the karaoke performance. First, a telop display task is started (S230), data indicating the type of operation mode stored in the DRAM 25 is read from the DRAM 25, and whether or not the operation mode is the display state 1 is referred to by referring to the read data. Judgment is made (S240). If it is determined that the operation mode is display state 1 (S240: YES), color change telop display processing is executed with reference to “MIDI-telop synchronization data” stored in the DRAM 25 (S250). Specifically, the image output from the graphics processing unit 11 illustrated in FIG. 8A is inverted because the video inversion circuit 26 is set to OFF because the operation mode is the display state 1. It is output without being processed and displayed on the display area 24a of the display 24 (see FIG. 8B). And the display color of the lyrics telop currently displayed on the display area 24a of the display 24 is changed in order according to a karaoke performance (refer FIG. 6). On the other hand, when it is determined that the operation mode is not the display state 1 but the display state 2 (S240: NO), the scroll telop display process is performed while referring to “MIDI-telop synchronization data” stored in the DRAM 25. Execute (S260). Specifically, the image output from the graphics processing unit 11 illustrated in FIG. 8A is inverted because the video inversion circuit 26 is set to ON because the operation mode is the display state 2. It is processed and output and displayed on the display area 24a of the display 24 (see FIG. 8C). Then, the image displayed in the display area 24 a of the display 24 is reflected to the rear of the integrated karaoke apparatus 100 by the mirror main body 29 a of the half mirror 29. An image shown on the mirror main body 29a of the half mirror 29 at this time is illustrated in FIG. Then, the color of the lyrics telop is changed at the lyrics position to be sung of the lyrics telop being displayed in the display area 24a of the display 24, and the color changing position is not changed even if the karaoke performance is progressed. Is scrolled in the horizontal direction in accordance with the karaoke performance (see FIG. 6B). When the color change telop display process or the scroll telop display process based on the lyrics telop data is completed, the present telop display task is terminated (S270).

(C) Background video output task (S280 to S310)
The background video output task is a task for displaying the background video data included in the song data on the display 24 in accordance with the karaoke performance. First, the background video output task is started (S280), data indicating the type of operation mode stored in the DRAM 25 is read from the DRAM 25, and whether or not the operation mode is the display state 1 with reference to the read data. Is determined (S290). When it is determined that the operation mode is the display state 1 (S290: YES), a background video output process is executed (S300). Specifically, the background video is displayed on the display area 24 a of the display 24. As a result, an image composed of the lyrics telop by the telop display task and the background video by the main background video output task is displayed in the display area 24a of the display 24 (see FIG. 6A). If it is determined that the operation mode is not the display state 1 but the display state 2 (S290: NO), the process proceeds to S310 to be described later, and the background video output task is terminated. In this case, since the background video output process described above is not executed, only the lyrics telop by the telop display task is displayed in the display area 24a of the display 24. That is, in the display area 24a of the display 24, an image obtained by deleting the background video from the image composed of the lyrics telop by the telop display task and the background video by the background video output task is displayed (FIG. 6B). reference).

When the background video output process ends, the background video output task ends (S310).
When the above three tasks (a) performance task (S200 to S220), (b) telop display task (S230 to S270), and (c) background video output task (S280 to S310) are completed, karaoke performance processing (S320), and the process returns to S110.

[Effect of the first embodiment]
(1) Thus, according to the integrated karaoke apparatus 100 of 1st embodiment, there exist the following effects. That is, when the display 24 is in the display state 1, the karaoke singing is performed in front of the integrated karaoke apparatus 100 by directing the display area 24a to the front of the integrated karaoke apparatus 100 as illustrated in FIG. The image is displayed to the performing singer and other users (viewers) (see FIG. 6A). Further, as illustrated in FIG. 5, when the half mirror 29 is attached to the housing 100 a, the image displayed on the display area 24 a of the display 24 in the display state 2 is displayed as the integrated karaoke apparatus 100. Reflects toward the back of the. Further, when the half mirror 29 is attached to the housing 100a in this way, the image displayed in the display area 24a of the display 24 is reversed left and right (see FIGS. 6B and 8D). In this case, the singer behind the integrated karaoke apparatus 100 and the audience (viewer) in front of the integrated karaoke apparatus 100 can be seen from each other through the half mirror 29. This makes it difficult for a singer who performs karaoke singing behind the integrated karaoke apparatus 100 to see the image displayed in the display area 24a of the display 24 in the display state 2, and the singer's eyes In addition to the stability of the singer's face as seen by the viewer (audience). Therefore, when the integrated karaoke apparatus 100 is used in a banquet hall, the singer can perform karaoke singing with a natural appearance even if the karaoke is in a positional relationship with the audience.

  (2) Further, according to the integrated karaoke apparatus 100 of the first embodiment, when the mirror main body 29a of the half mirror 29 is attached to the front corner of the upper portion of the housing 100a, the attachment portion 29b is interposed. Thus, it is configured to be positioned above the display area 24a of the display 24 in the display state 1 by the amount attached to the upper part of the housing 100a.
