PROBLEM TO BE SOLVED: To provide a graphic processor whose circuit scale is hardly increased with respect to a conventional graphic processor and which can fast perform graphic plotting when the entire graphic exists in a display area or when a graphic is a circulating graphic, the left edge of the graphic exists in anon- display area and the edge of the graphic exists in the display area, and to provide a graphic processing method. SOLUTION: When pixel data being a processing object is decided as existing within the display area in a step ST6, the pixel data are plotted from left to right. Namely in step ST3, the pixel data constituting a graphic are decided as pixel data to be plotted from the left edge of the graphic to the right, and in a step ST6, plotting is performed. Plotting processing of a graphic 4B is not performed and the processing of a set ST7 is carried out after performing plotting up the right edge of a graphic 4A. Graphics can fast be plotted because the plotting processing of the graphic existing in the non-display area is not performed. |
