摘要： An image control apparatus includes a waveform equalizer, a distorted waveform extraction control unit, a noise reduction circuit, and an image quality control unit. The waveform equalizer receives an input video signal, equalizes the waveform of the video signal, and outputs the waveform equalized video signal. The distorted waveform extraction control unit detects a distorted waveform from the output of the waveform equalizer and controls the waveform equalizer to perform waveform equalization suitable for the input video signal. It also controls the noise reduction circuit and the image quality control unit in accordance with changes in the frequency characteristic of the video signal before and after waveform equalization to intensify the noise reduction for degrading the image quality, when the high frequency band of the frequency characteristic of the input signal has been lowered, and, conversely, to debilitate or stop the noise reduction for enhancing the image quality, when the high frequency band has been raised.
