PURPOSE:To enable distortion correction facilitating adjustment by changing horizontal delay time in a vertical picture direction by one variable resistor while fixing horizontal delay time at the center of the picture. CONSTITUTION:The output of an amplifier 6 is connected to the input of an inverted amplifier 12, one terminal of a variable resistor 13 is connected to the output of the amplifier 6, the other terminal is connected to the output of the inverted amplifier 12, and a sliding terminal is connected to one terminal of a resistor 4. A second capacitor 14 is connected between the sliding terminal of the variable resistor 13 and a ground potential. While fixing the horizontal delay time at the center of the picture, the horizontal delay time in the vertical picture direction is changed by this one variable resistor 13. Thus, distortion correction facilitating adjustment can be executed. |
