Abstract
An apparatus is arranged to perform an equalizing process for equalizing an input signal including a video signal, to obtain a reproduced video signal by performing reproducing processes on the signal equalized and to vary the equalizing characteristic of the equalizing process during a period other than a period during which the reproduced video signal is in process of being obtained. The arrangement enables the apparatus to prevent the reproduced video signal from being affected by changes of the equalizing characteristic and to optimize the equalizing characteristic without impairing the quality of reproduced images.
