Abstract

PURPOSE:To achieve double scanning without reduction in vertical resolution with a comparatively simple circuit, by using the 1st luminance signal converted into a double scanning frequency as an interpolation signal of scanning lines, in a double scanning receiver of NTSC system. CONSTITUTION:The 1st luminance signal Y1 before a prescribed period from the present time, the 2nd luminance signal Y2 further before the prescribed period and a chroma signal C are separated from a composite video signal S2 by using a comb type filter circuit and converted into a double scanning frequency, and the 1st luminance signal YA1 is used as an interpolation signal of scanning line inserted between normal scanning lines. The inserted interpolation signal YA1 is operated at an interpolation operating circuit 8. Thus, the horizontal scanning frequency is doubled to the normal horizontal scanning frequency.
