initiate a time control 37 servo control the external clock process 36 initiates the time control 37 every time a time period of 1 frame namely time interval used to display 1 frame by picture apparatus 1 process b the time control acquires data from a motion data file 38 which are arranged in the order of the frame number process d while using this data as an instruction value the servo control is carried out process e so that operation of a motion base is realized during operation motion data having a format of fig4 for each of frames is derived every an external clock time period an instruction value is outputted to a servo process e and a feedback g is monitored to operate so as to realize a control in connection with a picture in this case symbol u201c unsigned char u201d is 1 byte data without code symbol u201c unsigned short u201d shows 2 byte data without code and symbol u201c long u201d represents double precision floating decimal point data however this process operation would cause a difference with respect to the motion control apparatus for originally controlling the frame display period as a constant frame display period since this frame display.
