A figure drawing device includes; a device 2 for increasing/decreasing the number of pixels on a scanning line up to the final painting pixel by one pixel; a device 3 for increasing/decreasing the number of scanning lines for drawing by one line; a device 4 for outputting drawing pixel data based on the control by the devices 1 and 2; a stencil buffer 5 for holding figure data in an intermediate stage of sequentially drawing a figure; a device 6 for holding pixel data read from the buffer 5 and consecutive as plural pieces of pixel data; a device 7 for detecting the transit state of the data value in the device 6; and a device 8 for inverting/non-inverting the logical operation result of the output data of the device 4 and the data in the device 6 and writing a result to the buffer 5.
