Abstract
PURPOSE:To fill up inside the contour by giving the plane data to the picture memory as the contour data and then giving the prescribed logic signal within the region enclosed by the contour at the reading time. CONSTITUTION:The closed loop data which is accompanied by no luminance information but to be the contour of the plane picture is written into plane growing memory plane 8 corresponding to the screen. For the generation of the plane picture, plane 8 is scanned in a fixed direction, and a closed loop is formed when the memorized closed loop data is read out. The fixed logic signals are generated continuously for the period during which signal of ''1'' is detected to become ''0'' once and then the ''1'' signal is detected again. In this way, the inside of the region enclosed by the closed loop is filled up with the prescribed display data to display the plane data.
