Image distortion correction apparatus capable of correcting misconvergence using an amplifier

摘要

An image distortion correction apparatus is disclosed which can correct misconvergence using a D-class amplifier. The image distortion correction apparatus has an image processor for detecting an image signal and horizontal/vertical synchronous signals from a signal received from an external source; a distortion value calculator for calculating a misconvergence value occurring when the image signal is scanned based on the horizontal/vertical synchronous signals; a correction value calculator for calculating a convergence correction value of a pulse waveform to correct misconvergence of the image signal based on the misconvergence value; an amplifier for performing a D-class amplification with respect to the convergence correction value; and a convergence yoke fixed to a cathode ray tube (CRT) for controlling a path of an electron beam corresponding to the image signal based on the convergence correction value amplified in the amplifier.
