Abstract
In a noise reducer whose S/N improving amount is variable, as to such a region where image quality deterioration caused by the noise reducer becomes relatively apparent, and both a luminance level and a chroma level are low, the S/N improving amount thereof is decreased. To the contrary, as to such a picture having a dark high frequency range component and a small movement component, no control is made of the S/N improving amount by the above-described luminance level and chroma level, but the normal S/N improvement is sufficiently carried out.
