PURPOSE:To alter the transition speed of a picture even in a curved orbit by calculating the curved orbit of the transition of the picture obtained by passing through plural given positions in given order and by varying the speed in respective sections among points on the orbit. CONSTITUTION:An elapsed time (t) and a transition time T are inputted in a moving distance calculation circuit 1 so as to calculate the moving distance (x). At the same time, parameters of the picture y-1, y0, y1 and y2 are inputted so as to obtain the coefficient of the equation of an orbit curve in an orbit curve coefficient calculation circuit 2 which calculates a smooth curve. Inputting outputs from two circuits 1 and 2, an interpolation data calculation circuit 3 generates interpolating data (y). By separately calculating the coefficient of the equation of the orbit curve and the transition speed, thus, the transition speed can be varied in the curved orbit.
