First, as shown in FIG. 9A, when the object on the field 112 moves from position (X1, Y1) (this is called the original position) to position (X2, Y2) (this is called the previous position). To do. When the drive signal is generated in the present embodiment, it is considered by projecting the drive signal on the projection surface 113 virtually located between the position of the camera 110c (camera position 111X) and the field 112. That is, the movement vector calculated with the field 112 as the reference plane is
Camera 1 depending on where this movement vector is located
The control amount of 10c changes. In order to eliminate this, in the present embodiment, the original position and the destination position are projected onto a projection surface 113 as shown in FIGS. 9B and 9C, and the movement vector of the object is set with reference to this projection surface 113. (This is called a control vector). Further, the drive signal is obtained from a table in which the obtained control vector and the drive signal are associated with each other, and is obtained by generating this as an electric signal by a waveform generating circuit or the like not shown. However, more accurately, the projection surface 113 needs to be a spherical surface centered on the camera position 111X.
