A drawing device that includes a triangle detecting unit specifying a triangle to be drawn and specifying a pixel block having a pixel of the triangle and includes a B-edge detecting unit judging whether or not the pixel block specified by the triangle detecting unit includes a pixel of a triangle that is connected to the triangle. The drawing device also includes a rasterizing unit that, when the B-edge detecting unit judges that the pixel block specified by the triangle detecting unit includes the pixel of the triangle, performs the rasterization processing on the pixel block so that pixel data is generated, includes a memory R/W unit writing the pixel data of the pixel block that is generated by the rasterizing unit into a memory, and includes a drawing engine controlling a display of an image in accordance with the pixel data written into the memory.
