GRAPHICS PLOTTING DEVICE AND GRAPHICS PLOTTING METHOD

When moving images such as three-dimensional graphics, or the like are displayed, high-quality images can be displayed by keeping a display frame rate, suppressing a breakdown of display contents, and making a drawing engine exhibit processing abilities to maximum. A graphics rendering device includes a frame buffer 40 in which a plurality of areas are provided, a rendering frame counter 15 for counting a number of frames in which the rendering is ended, a display frame counter 17 for counting a number of frames in which a display on a screen is completed within respective frames whose rendering is ended, a rendering controlling portion 11 for determining whether or not an empty area is present on the frame buffer based on the value of the rendering frame counter and the value of the display frame counter and permitting the rendering of the display element in the next frame when the empty area is present, a rendering necessary-time predicting portion 13 for predicting a rendering required time, and a rendering omission controlling portion 12 for determining whether or not the rendering is completed before display based on the value of the display frame counter, a display period of the frame, and a predicted rendering required time and going to a process in the next frame by omitting an execution of a succeeding rendering command when the rendering is not completed.
