  The video reproduction control unit 28 reproduces only the background video extracted from the video DB 25 corresponding to the selected music, or displays the lyrics telop extracted from the music DB 26 corresponding to the music on the background video. Based on this, here, the display control is performed by the control signal for displaying / not displaying the lyrics telop from the lyrics display control means 30 to be described later.

  The input unit 29 inputs a normal signal from the operation panel 17, and here, from a selection button for selectively displaying a lyrics telop on either the first image or the second image. The selection signal is sent to the lyrics display control means 30. The lyric display control means 30 is a program that controls the display of the lyric telop to be played on the first display image or the second image on the directional display unit 13, and is expanded in the RAM 24 and executed. Is done.

  Here, FIG. 2 shows an explanatory diagram of the lyrics telop control display by the directional display unit of FIG. In FIG. 2A, the directional display unit 13 shows a planar state (a state from above). Here, it is assumed that a singer 31 who visually recognizes the directional display unit 13 and another listener 32 are divided into left and right with respect to the directional display unit 13, and And singing on the left side. In response to this, the directional display unit 13 has a first angle range (left side in this case) in the horizontal direction on the display surface (from the horizontal central portion of the directional display unit 13). The first image is displayed in a display area (viewing area) whose viewing angle is θ1 (expressed as an angle), and the other second angle range (similarly, the angle from the horizontal central portion of the directional display unit 13) The second image is displayed in a display area (viewing area) in which θ2 is a viewing angle.

  In a normal karaoke apparatus, a background video 41 corresponding to a musical piece to be played is displayed, and a lyrics telop (lyric telop data) 42 is displayed on the background video 41. In the present invention, for example, a singer 31 Only the background video 41 is visually recognized, and the background image 41 and the lyrics telop 42 are visually recognized by the observer. Only the background video 41 is displayed on the first image (FIG. 2B), and the second The background video 41 and the lyrics telop 42 are displayed on the image (FIG. 2C).

  FIG. 3 shows a processing flowchart of the lyrics telop control display of FIG. In FIG. 3, first, the user selects the lyrics telop display from the operation panel 17 and inputs the selected lyrics telop display selection signal at the input unit 29, so that the lyrics display control means 30 is set ( Step (S) 1). Subsequently, when a request signal for a song is input from the user, for example, from the operation panel 17 or the like (S2), the song data of the song is extracted from the song DB 26 by the algorithm of the central control unit 22 and the music song is output. The lyrics telop data 42 and the background video data 41 of the song song extracted from the video DB are sent to the video playback control unit 28 (S3).

  The lyrics display control means 30 sends a control signal for displaying the lyrics telop data 42 on the second image to the video reproduction controller 28 in accordance with the set lyrics telop display selection signal (S4). The video reproduction control unit 28 causes the directionality display unit 13 to display the first image of only the background video 41 and the second image of the background video 41 and the lyrics telop 42 of the lyrics data. (S5).

  In the above embodiment, the singer 31 is allowed to visually recognize only the background image 41 of the musical composition, and the listener 32 is displayed with the background image 41 and the lyrics telop 42. May be a case where only the background image 41 of the performance music is visually recognized and the background image 41 and the lyrics telop 42 are displayed on the singer 31 (that is, the first image and the second image are shown in the figure). Meaning it will be reversed). Thereby, it is possible to make the listener 32 feel as if the singer 31 is singing without looking at the lyrics telop 42 even if the singer 31 does not memorize the lyrics. The same applies to the following embodiments.

  Thus, while making the singer 31 visually recognize the first image or the second image of the lyrics telop displayed or hidden, the listener can make the first image or the first image hidden or displayed opposite to the lyrics telop displayed. 2 allows the user to easily and efficiently embody the simultaneous display and non-display of the lyrics telop on the same screen without requiring troublesome operations by the user. is there.

  Next, FIG. 4 shows a block diagram of a second embodiment of the karaoke apparatus provided with the display control system according to the present invention.

The horizontal rotation drive unit 51 is a mechanism for rotating the direction display unit 13 in the horizontal left-right direction, and the rotation direction and the rotation angle are controlled by the display unit angle adjustment unit 52. The display unit angle adjusting unit 52 is a program for controlling the horizontal rotation driving unit 51 by specifying the rotation direction and the rotation angle of the directional display unit 13 and is developed in the RAM 24 and executed.

  FIG. 5 is an explanatory diagram of the display unit angle adjustment of FIG. 5A and 5B, the directional display section 13 shows a planar state (a state from above). That is, in FIG. 5A, the entire display surface of the directional display unit 13 is rotated to the right at a predetermined angle (θ3) with respect to the left and right in the horizontal direction, and the entire display surface is directed to the right. Is the case. Even in this state, the first image (only the background video 41) and the second image (the background video 41 and the lyrics telop 42) are displayed separately at the same time.

  In FIG. 5B, conversely, the entire display surface of the directional display unit 13 is rotated leftward at a predetermined angle (θ4) with respect to the left and right in the horizontal direction, and the entire display surface is leftward. This is the case. Even in this state, the first image (only the background video 41) and the second image (the background video 41 and the lyrics telop 42) are displayed separately at the same time.

  The rotation of the directional display unit 13 in the left-right direction is based on the rotation direction and rotation angle control signals of the display unit angle adjustment unit 52 with respect to the horizontal rotation drive unit 51. The angle control signal is, for example, from the operation panel 17. The user may set appropriately. It is meaningful to make such rotation of the directional display unit 13 correspond to a place where the singer 31 sings (for example, on a stage platform different from the position of the listener 32).

  In this manner, the first image or the second image in which the lyrics telop is displayed or hidden is surely viewed with respect to the singing position of the singer 31, while the listener 32 is hidden or displayed in reverse of the lyrics telop. Since the first image or the second image displayed is visually recognized, it is easy and efficient to simultaneously display whether or not to display the lyrics telop on the same screen without requiring a troublesome operation by the user. It can be embodied.

  Next, in FIG. 6, the block block diagram of 3rd Embodiment of the karaoke apparatus provided with the display control system which concerns on this invention is shown. The karaoke apparatus 11 shown in FIG. 6 is obtained by adding a detection sensor 53 and a detection position specifying means 54 to the karaoke apparatus 11 shown in FIG. The detection sensor 53 can be realized by, for example, a CCD sensor, a 3D sensor, or the like, and is disposed, for example, at the upper center of the directional display unit 13 (see FIG. 8A).

  The detection position specifying means 54 is a program for detecting a predetermined detection target based on detection information from the detection sensor 53, specifying the position, and specifying the position of the singer, and is developed in the RAM 24 and executed. . Here, the microphone 15 of the singer 31 (for example, a windscreen of a microphone or a grill ball) is used as a detection target, and this image data is registered in advance. As an example of the position specifying process, for example, the microphone 15 (the above-described wind screen or grill ball) in the image data from the detection sensor 53 is extracted and specified, and for example, the center position of the image data from the detection sensor 53 is determined. The position of the singer 31 can be specified by specifying the left and right of the detection target specified as the reference. Note that another detection target may be used. For example, general facial feature data is registered, each facial feature is recognized from the image data from the detection sensor 53, and the preset rightmost person or leftmost person is the singer 31. It can be realized by specifying as.

  In contrast to the configuration of the detection sensor 53 and the detection position specifying unit 54, the display unit angle adjusting unit 52 displays the first image of the singer 31 from the position of the song 31 specified by the detection position specifying unit 54. The horizontal rotation drive unit 51 is controlled by specifying the rotation direction and the rotation angle for visual display.

  FIG. 7 shows a processing flowchart of the lyrics telop control display of FIG. 6, and FIG. 8 shows an explanatory diagram of the lyrics telop control display of FIG. First, as shown in FIG. 8A, the detection sensor 53 is disposed at the upper center of the directional display unit 13. The arrangement position of the detection sensor 53 may be any as long as the position of, for example, the display center of the direction display unit 13 in the sensor detection data (for example, image data) is specified or set.

  In FIG. 7, first, data (for example, image data) detected by the detection sensor 53 is input to the detection position specifying means 54 (S11). The detection position specifying means 54 recognizes the microphone 15 from the detection data, specifies the position of the microphone 15 in the left-right direction, and specifies the position of the singer 31 (S12). The display unit angle adjustment unit 52 determines the horizontal rotation direction and rotation angle of the directional display unit where the first image is visually recognized by the singer 31 from the identified position of the singer 31 and controls driving. A signal is sent to the horizontal rotation drive unit 51 (S13). Then, the horizontal rotation driving unit 51 drives the direction display unit 13 to rotate in the horizontal direction according to the determined rotation direction and rotation angle drive signal from the display unit angle adjustment unit 52 (S14). ).

  For example, when the microphone 15 (for example, the wind screen or the grill ball) is on the right side with respect to the detection sensor 53 (directional display unit 13) as shown in FIG. The rotation direction (right direction) and the rotation angle θ5 in which the first image (only the background video 41) enters the position are determined, and the directionality display unit 13 is rotated. In addition, when the microphone 15 (for example, the wind screen or the grill ball) is on the left side with respect to the direction display unit 13 as shown in FIG. The rotation direction (left direction) and the rotation angle θ6 in which the image (background image 41 only) enters are determined, and the directionality display unit 13 is rotated.

  In the above embodiment, the display unit angle adjusting unit 52 controls the horizontal rotation driving unit 51 so that the detection position is included in either the first angle range or the second angle range. The lyrics display control means 30 switches the display of the lyrics telop of the first image and the second image so as to reduce the rotation angle, inverts the first angle range and the second angle range, and sets it as a detection target. On the other hand, rotation angle comparison means (not shown) may be attached so as to be included in any of the inverted first angle range or the second angle range, which is the same as in the above embodiment. For example, when there are users on the left and right facing the direction display unit 13 (see “A” in FIG. 2), this function is used together when the detection target (singer) is switched to the left and right. Is preferred.

  In this way, the first or second image of the lyrics telop is displayed or hidden automatically and reliably with respect to the position of the singer 31 while the listener 32 reverses the lyrics telop. Since the first image or the second image that is displayed or displayed is visually recognized, it is easy and efficient to simultaneously display and hide the lyrics telop on the same screen without requiring a troublesome operation by the user. It can be embodied concretely.

  The karaoke apparatus provided with the display control system of the present invention can be used on the karaoke industry in which the karaoke apparatus displays and hides the lyrics telop.
