A graphics system including: a register storing data of a clipping frame of a frame buffer; a register storing offset data of a figure; a register storing data of a clipping frame of a stencil buffer that is larger than the clipping frame of the frame buffer and storing position data of a reference basing point, on a stencil buffer, for drawing a non-offset figure or an offset figure; and a pixel filling-in module for drawing onto a stencil buffer a masking determination result of a pixel relating to the figure on the basis of data of the clipping frame of the stencil buffer and the figure, and also drawing the non-offset figure or the offset figure onto the frame buffer by referring to the stencil buffer onto which the masking determination result is drawn, the position data of a reference basing point stored in the register, and the data of the clipping frame of the frame buffer.
