It is the schematic of the karaoke electrical decoration system in an Example. It is a lineblock diagram of an electric decoration control device and an electric fixture in an example.

=== Prerequisite system configuration ===
The outline | summary of the karaoke electrical decoration system which concerns on this invention is shown in FIG. The karaoke apparatus 1 basically has the same configuration as a well-known and commonly used karaoke apparatus, and the description of the well-known and commonly used karaoke technology is limited to the minimum necessary in this specification.

  In the present invention, the karaoke apparatus 1 transmits the music link data of a plurality of channels based on the karaoke data to the electrical decoration control apparatus 2 in the process of playing the accompaniment music based on the karaoke data. In addition, the karaoke apparatus 1 sequentially generates scoring data that evaluates the skill of the song based on the singing voice of the person who sings along with the accompaniment music in the process of performing the accompaniment music based on the karaoke data, and the illumination control apparatus 2 Send to.

  The illumination control device 2 sequentially generates control data for each LED lamp in the illumination device 3 based on the music linkage data sequentially received from the karaoke device 1. As shown in FIG. 2, the lighting fixture 3 includes a plurality of LED lamps 4 capable of emitting multicolor light, and the brightness and color of these LED lamps 4 are individually controlled by the lighting control device 2.

  Karaoke data is mainly composed of music generation data in an electronic score format such as MIDI. The music linkage data is part data of several musical instruments extracted from part data of a plurality of musical instruments constituting karaoke data. For example, drum part data in karaoke data is extracted as one piece of music linkage data as time-series information representative of the rhythm structure (beat structure) of the music being played. Further, base part data in karaoke data is extracted as one piece of music linkage data as time-series information representative of the progression of harmony of the music being played. Similarly, part data of a melody instrument that plays an active part in the prelude or interlude is extracted as music linkage data as time-series information representative of the musical composition of the music.

  As a preferred embodiment, which part data is extracted from the karaoke data of each music piece as music linkage data is set in advance as additional information of karaoke data for each music piece. In addition, an embodiment in which dedicated music linkage data for realizing music tuning decoration is created in advance for each piece of music and included as one part data of karaoke data is also preferable. However, an embodiment in which part data of some specific instruments of karaoke data is extracted as music linkage data may be used.

=== Dynamic Control of LED Lamp ===
The Example of the lighting fixture 3 is demonstrated. The illumination fixture 3 includes 128 LED lamps 4. The LED lamp 4 is a collective lamp including a red LED, a green LED, and a blue LED, and the luminance and color of the LED lamp 4 can be changed by changing each luminance of the three primary color LEDs to multiple gradations.

  As shown in FIG. 2, the electrical decoration control device 2 includes a microcomputer 21 and a constant current driver 22. The constant current driver 22 has a total of 384 output terminals that drive the red LED, green LED, and blue LED of the 128 LED lamps 4, and the constant current is supplied to the LEDs connected to the output terminals for a predetermined time. The brightness of the LED is adjusted according to the energization time. That is, each LED is driven to emit light by constant current pulse width control (PWM control).

  The microcomputer 21 generates 4-bit data (16 gradations can be expressed) as luminance data of each of the 384 LEDs, and serially inputs the data to the constant current driver 22 for latching. This operation is repeated at a period of 1/60 seconds. In other words, the microcomputer 21 generates 128 pieces of 4 × 3 = 12-bit lamp control data for designating the luminance and color of one LED lamp 4 at a repetition cycle of 60 times per second, and supplies it to the constant current driver 22. The brightness and color of the 128 LED lamps 4 can be changed by latching.

  The microcomputer 21 generates 128 pieces of lamp control data defining the brightness and color of each LED lamp 4 based on the music linkage data supplied from the karaoke device 1 by a process executed at a period of 1/60 seconds. To do. Thereby, the electric decoration which the change of the brightness | luminance and color of 128 LED lamps 4 interweaves with the accompaniment music currently performed in the karaoke apparatus 1. FIG.

  As disclosed in many technical literatures, various methods are conceivable as processing for synchronizing the electric decoration woven by changes in luminance and color of the 128 LED lamps 4 with the accompaniment music based on the music linkage data. For example, in the microcomputer 21, a different control function is programmed for each LED lamp 4, and the lamp control data is calculated by appropriately incorporating music linkage data in the parameters of each control function, and each LED lamp and each control function are calculated. Are rearranged based on appropriate music linkage data.

  This creates a blinking expression of the LED lamp based on the music linkage data that reflects the rhythm structure (beat structure) of the music, creates a combination of lighting colors that reflect the progression of the harmony of the music, and reflects changes in the volume of the music It produces the expression of the movement, convergence, and diffusion of the illumination light that reflects the performance of the solo instrument in the prelude and interlude in the music. Since the lamp control data is updated at a period of 1/60 seconds as in the embodiment, it is possible to produce a lively music tuning decoration with a very sense of speed. This is called dynamic control of the LED lamp 4.

=== Introduction of static control ===
The present invention is characterized in that, in addition to the above-described dynamic control, the concept of static control is also adopted. That is, in the above description, all 128 LED lamps 4 of the lighting fixture 3 are described as dynamically controlled based on the music linkage data, but are not necessarily controlled as such. Some of the LED lamps 4 are excluded from the target of dynamic control and are subject to static control.

  The static control of the LED lamp 4 is typically to keep the LED lamp 4 in an extinguished state. Alternatively, the LED lamp 4 is made to emit light but is kept at a very low brightness. When all 128 LED lamps 4 are dynamically controlled as described above, the lighting fixture 4 is in the most gorgeous state. If, for example, 78 LED lamps 4 out of 128 are maintained in a light-off state as static control targets, the number of dynamically controlled LED lamps 4 is 50, so that the glare is greatly reduced. Become.

=== Scoring data and number of static control target lamps ===
In this invention, the karaoke apparatus 1 sequentially generates scoring data that evaluates the skill of a song based on the singing voice of a person who sings along with the accompaniment music in the process of performing the accompaniment music based on the karaoke data, and controls the illumination. Transmit to device 2. Based on the received scoring data, the microcomputer 21 of the illumination control device 2 designates a larger number of LED lamps 4 as static control objects as the scoring data is worse. The relationship between the scoring data and the number of lamps may be determined uniformly, or some variation factor may be taken into account.

=== Designation of static control target ===
When the microcomputer 21 of the illumination control device 2 determines the number of static control target lamps based on the scoring data, the lamps for the number of 128 LED lamps 4 are designated as static control targets. To do. Assuming that the number of static control target lamps is 78, for example, among the 128 LED lamps 4, 78 randomly selected lamps are designated as static control targets. This selection method is not limited to random, but may have some regularity associated with the arrangement of all 128 LED lamps 4. The lamp designation of the static control target may be dynamically changed.

  As described above, the microcomputer 21 is connected to the music supplied from the karaoke apparatus 1 with 128 pieces of lamp control data defining the brightness and color of each LED lamp 4 by a process executed at a period of 1/60 seconds. When generated based on the data, lamp control data by dynamic control for a plurality of LED lamps 4 designated as static control targets is ignored and not output, and instead, control data for turning off the corresponding LED lamp 4 ( 4 × 3 = 12 bits are all zero). Of course, for a statically controlled lamp, all zeros may be output without calculating dynamic control lamp control data.

  Since the karaoke device 1 gives the lighting control device 2 the scoring data that evaluates the skill of the song for each predetermined scoring section, the karaoke device 1 is maintained in the static control target (the light is turned off) during the process of singing the karaoke by the user. The number of LED lamps 4) changes, and if the karaoke device 1 scores when the song is sung well, the gorgeousness of the music tuning decoration increases, and if the karaoke device 1 does not sing well, the karaoke device 1 scores In this case, the gorgeousness of the music tuned lights will decrease. Therefore, both the person who is singing and the person who is listening can enjoy the joy of music tuning and singing.

  The thrilling enjoyment of music-tuned lighting reflecting the singing score according to the present invention is configured such that the greater the number of LED lamps 4 not designated as static control objects, the higher the brightness of these LED lamps 4. In addition, as the number of LED lamps 4 that are not designated as static control objects increases, the number of colors emitted from the LED lamps 4 is increased to make the LED lamp 4 more prominent.
