Abstract
Abstract An image processor for displaying a predetermined moving figure includes a reference point memory for storing data on a plurality of reference points; each reference point is for displaying the figure in according to a series of movements of the figure. The image processor also includes, a control point memory for storing data for a plurality of control point. Each control point is for determining another position of the figure relative to each reference point. The image processor also includes, an operation unit for outputting a movement command to the figure and an image display unit for performing an image process to display the figure in an area of a coordinate system determined by the reference point and the control point in accordance with the movement command. When the control point is changed to another position, the position and disposition of the figure in the predetermined coordinate system are immediately calculated.
