That is, in FIG. 5A, the display surface of the directional display unit 13 is tilted by rotating at a predetermined angle (θ3) as an elevation angle in the vertical downward direction (counterclockwise in the figure). This is a case where the surface is directed downward. 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 display surface of the directional display unit 13 is tilted by rotating (clockwise in the figure) at a predetermined angle (θ4) as an elevation angle upward in the vertical direction. This is a case where the display surface is directed upward. 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 is based on a control signal of the display unit angle adjustment unit 52 with respect to the elevation drive unit 51, and the angle control signal is appropriately set by the user from the operation panel 17, for example. Good. It is meaningful to make such rotation of the directionality display unit 13 correspond to, for example, the height of the singer 31 and the singing place of the singer 31 (for example, on the stage platform).

  In this way, the first or second image of the lyrics telop is displayed or hidden reliably with respect to the viewing position of the singer 31 while the listener 32 reversely hides the lyrics telop or 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, near the central portion in the vertical direction of the directional display unit 13 (see FIG. 8A).

  The detection position specifying means 54 is a program that specifies the height position of a predetermined detection target based on the detection information from the detection sensor 53 and specifies the visual position of the singer 31 and is developed and executed in the RAM 24. The 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 visual recognition position of the singer 31 can be specified by specifying the height 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, the singer 31 is identified by the highest face data, and the viewing position is determined. It can also be specified.

  In contrast to the configuration of the detection sensor 53 and the detection position specifying means 54, the display unit angle adjustment section 52 is the first to the singer 31 from the visual position of the singer 31 specified by the detection position specifying means 54. The elevation angle drive unit 51 is controlled by specifying the elevation angle to display the image.

  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 a side portion of the directional display unit 13 and is arranged near the center in the vertical direction. The arrangement position of the detection sensor 53 is kept horizontal with respect to the floor surface, and the reference height (for example, horizontal center portion) of the image data is set to the reference height (for example, horizontal center position) of the direction display unit 13. Since the height position of the detection target can be easily specified by making it correspond, it may be either up, down, left, or right with respect to the directionality display unit 13 or may be in another place. Good.

  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 height position from the reference (horizontal position) of the microphone 15, and specifies the visual position of the singer (S12). The display unit angle adjustment unit 52 determines the elevation angle of the directional display unit 13 at which the first image is visually recognized by the singer 31 from the identified visual position of the singer 31 and displays the drive control signal as the display unit angle adjustment unit. 51 (S13). Then, the elevation angle drive unit 51 rotates the directional display unit 13 to the elevation angle with respect to the vertical direction according to the drive signal of the determined elevation angle 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 located below the horizontal position of the detection sensor 53 (directional display unit 13) as shown in FIG. The elevation angle θ5 at which the first image (only the background image 41) is displayed at the viewing position is determined, and the directionality display unit 13 is rotated counterclockwise in the drawing. In addition, when the microphone 15 (for example, the wind screen or the grill ball) is above the horizontal position of the detection sensor 53 (directional display unit 13) as shown in FIG. The elevation angle θ6 at which the first image (only the background image 41) is displayed at the visual recognition position of the person 31 is determined, and the directionality display unit 13 is rotated clockwise in the drawing.

  In this manner, the first or second image of the lyrics telop is automatically or reliably displayed with respect to the viewing position of the singer 31 while the listener 32 reverses the lyrics telop. Since the first image or the second image that is not displayed or displayed is visually recognized, it is easy and simultaneous to display and hide the lyrics telop on the same screen without requiring troublesome operations by the user. It can be realized efficiently.

  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.
