<p>When displaying a dynamic image such as 3D graphics, it is possible to display a high-quality image by maintaining the display frame rate, suppressing a failure of display content, and using the maximum processing ability of the plotting engine. A graphics plotting device includes: a frame buffer (40) having a plurality of regions; a plotting frame counter (15) which counts the number of frames which have been plotted; a display frame counter (17) which counts the number of frames which have been displayed on the screen among the frames whose plotting is complete; a plotting control unit (11) which judges whether the frame buffer has an empty region according to the value of the plotting frame counter and the value of the display frame counter and allows plotting of the next frame if an empty region exists; plotting time prediction unit (13) which predicts the time required for the plotting; and a plotting omit control unit (12) which judges whether the plotting is complete before display according to the value of the display frame counter, the frame display cycle, and the predicted plotting time and, if no, omits execution of the subsequent plotting command to proceed to processing of the next frame.</p> |
