[PROBLEMS] To provide a color number correlation apparatus capable of maximizing the sensitivity of a correction circuit in a color number correlation apparatus used as a television or a computer display, and to provide a color number correlation apparatus capable of remarkably reducing a resistance value.;[MEANS FOR SOLVING PROBLEMS] The present invention relates to an image processing apparatus and an image processing method for an image processing apparatus, which includes a color number correlation provided in an inline type electron gun at a neck portion, and a horizontal deflection coil used together with the color number correlation to generate a horizontal deflection magnetic field distorted in a pincushion-And a deflection yoke having a vertical deflection coil for generating a vertical deflection magnetic field, characterized in that the deflection yoke has a YH correction circuit connected in series with the vertical deflection coil, The YH correction circuit has a diode bridge circuit connected in parallel with at least one resistor, and the two resistors are connected in series to each other. A series body and a variable resistor are connected in parallel and the parallel body is connected between the output terminals of the diode bridge circuit, A bridge circuit is formed by connecting the YH correction coil between the movable terminals of the variable resistors to constitute a double bridge circuit and the YH correction coil is arranged symmetrically with respect to the horizontal axis and the vertical axis of the deflection yoke.
