<p>PURPOSE:To make a converting function to convert a PPI detected image to a scanning in all directions unnecessary, by displaying a display of a detected signal by a multiple circumferential line scanning and a display of a code signal by a scanning in all directions in layers. CONSTITUTION:A cathode ray tube having a displaying surface 1 in a square shape is used, and a composite display scanning in which a display scanning to display a projected image on the cathode ray tube is continued to a multiple circumferential line scanning 2 by a spiral linear scanning or a multiple circular scanning etc. and a scanning in all directions 3 consisting of a linear scanning and a main scanning and an auxiliary scanning in a direction orthogonal to this, is performed. By such a display method, a converting function to convert a PPI detected image to a scanning in all directions in unnecessary.</p> |
