Abstract
PURPOSE:To obtain an image of true circle, by selecting a recording time per one image element, so as to make the aspect ratio of sectional plane on a recording paper expressing the density information of one video element approximately same as the aspect ratio of the image elements. CONSTITUTION:A video signal is video-amplified 1, the density information of the image element is written in an image memory 4 and the density information is read out in a sequential drawing control section 6, and actual drawing is made at a recording section 7 according to the output signal. This recording section 7 is of thermo-sensing type, the thermal head is scanned toward the main scanning direction, and the heat sensing recording papers is moved toward the sub-scanning direction vertical to the main scanning direction in synchronizing with the movement of head. In the said drawing control section 6, the image of a true circle is obtained by the main scanning of 4/3 times the recording time in case of the aspect ratio of 1:1 for the sectional plane on the recording paper.
