PROBLEM TO BE SOLVED: To provide a display system that draws an image of an analog type display device in computer graphics and reconciles smoothness of the movement of the image with accurate display.SOLUTION: Before an image synchronization time point Tsync in a display device, the reception time point of display data nearest to the Tsync is denoted with Tnew, its previous reception time point is denoted with Tpre, and the difference between the Tsync and the Tnew is denoted with T. Of the points interpolated between a point A1 corresponding to the Tpre and Vpre and a point A2 corresponding to the Tnew and Vnew, the point of the position right by the T from the point A1 on the horizontal axis is denoted with C1, and the value of the C1 on the vertical axis is set as an interpolation value. The guide indicating this interpolation value is drawn and is displayed at the time point Tsync.SELECTED DRAWING: Figure 4 |
