The method and apparatus for eliminating the "sawtooth" effect of the image profile during the scanning of the picture are disclosed. By using the sub-vertical deflection correcting signal which corresponds to the direction and slope of the image profile, the scanning is made along the edge of the profile. The apparatus consists of the profile detector, generator of sub-vertical deflection correcting signal, driving circuit, sub-vertical deflecting coil and the delay circuit.
