PURPOSE:To accurately and quickly output an image including a circular graphic by converting circle data to runlength data, re-arranging the runlength data, and converting the runlength data to an image signal. CONSTITUTION:When the image data of circle data is inputted, a circle data storage means stores the radius of a circle, a center point, the thickness of a circumference line, and a circle data index. Also, a circle data conversion means converts taken out circle data to the runlength data, and a runlength data storage means holds output image data of runlength format. An arrange ment control means performs control to rearrange the runlength data, and a runlength data conversion means converts rearranged runlength data to the image signal. Thereby, it is possible to quickly and accurately convert the image data to the runlength data. |
