An apparatus for reducing Moire interference in a color cathode ray tube produced due to inconsistent spacing of scanning lines with respect to the dot pitches of a shadow mask during the display of video signals. The apparatus includes a sync signal dividing section for dividing by 2 horizontal and vertical sync signals separated from an input video signal, a vertical position control signal output section for outputting to a vertical position control section a voltage signal which varies according to a scanning Moir+E,acu e+EE control signal selectively inputted by a user, and a horizontal position control signal output section for outputting to a horizontal oscillation control section a voltage signal which varies according to a video Moir+E,acu e+EE control signal selectively inputted by the user, so that the vertical position of the even or odd scanning lines as well as the horizontal position of the even or odd image dots are adjusted to suppress the Moir+E,acu e+EE interference. |
