1, a display unit 12, a display information determination unit 13, a display information buffer unit 14, and a display content update unit 15.

The input interface section 11 provides at least one of pitch, strength, key release speed, pitch continuous change, or keystroke pressure information and musical tone on / off switching information from the musical instrument operation information or acoustic signal. It is a thing. Further, among performance information, the strength may be given as a keystroke speed, and in the following description, the strength information may be described as a keystroke speed. The keystroke pressure is information corresponding to the change in volume of the sound after the start of sounding or the strength with which the keyboard of a keyboard instrument is pressed. The continuous pitch change is, for example, a change when the pitch is changed by changing the tension of a string in a string instrument, or when the pitch is continuously changed like a pitch bender used in a music synthesizer or the like. Information. In addition, as such a device, for example, an MPU40 manufactured by Roland Co.
1 and the like complying with the MIDI standard are widely spread, and the information required in the embodiment of the present invention is MIDI.
It can be given within the standard. However, in implementing the present invention, the input interface unit 11 is
It does not have to be the DI standard, and any standard may be used as long as it gives the information listed above. For example, as a standard other than the MIDI standard, the present invention can be implemented by the DCB standard used by Roland.

The display information determining section 13 determines the position, the color, the shape, the size, the direction, the position change speed, the color change speed, the shape change speed, and the size of the figure to be displayed according to the performance information obtained from the input interface section 11. The display information regarding the speed change rate and the direction change speed is determined and output to the display information buffer unit 14. For example, the display information is stored in a table having an n-dimensional index for each of the n types of information in the performance information obtained from the input interface unit 11, and in operation, depending on the contents of each of the n pieces of information. Thus, it can be realized by a device for retrieving and outputting display information of previously registered figures. An example of the case where n is 2 is shown in FIG. Here, each performance information is assumed to take a value from 0 to 127. As shown in FIG. 28, the display information regarding the position, color, shape, size, and direction of the graphic is described as each element of the two-dimensional matrix. In FIG. 28, only the position, color, shape, size, and direction in the graphic display information are described, but other graphic display information may be described together, or the number may be smaller. As a result, in this example, during operation, it is possible to retrieve and obtain display information relating to the position, color, shape, size, and direction of the figure by the values of the two performance information provided.

In order to set the speed and update the position, color, shape, size, or orientation based on the time change based on the setting, the display content update unit 15
It is necessary to include the timing means therein, but it is not necessary to include the timing means when the change due to the speed is not used. Further, as an example of a method of checking whether or not the speed is set, there is a method of checking whether or not the absolute value of the speed is 0. That is, according to this inspection method, if the absolute value of the speed is 0, it is considered that the parameter in the graphic display information related to the speed does not change with time thereafter,
It considers that the speed is not set.

In the screen coordinate system (S _x , S _y ), that point corresponds to a point on the locus of a parabola with X as a parameter. Eventually, the coordinate system (X, Y) is set on the parabola on the (S _x , S _y ) plane, but such a method is also an example of the coordinate system, and setting this conversion By this, even if the movement of (X, Y) is a simple constant velocity linear movement, the display figure can be moved like a falling movement along a parabola. Further, it is also an example of the coordinate system to simply set S _x = X and S _y = Y, and in this case, the position information obtained from the display content updating unit is used without conversion.
