ABSTRACT:
A plurality of bandpass filters extract high frequency components of a digital image signal sampled every predetermined unit, thus generating a plurality of high frequency signals. The high frequency signals are added to produce a resultant high frequency signal. On the basis of the value of the resultant high frequency signal, the maximum value or minimum value detected from the high frequency signals is selected. The resultant high frequency signal and the selected maximum or minimum value are added according to determined weights, so that an enhancement signal is generated. Edge enhancement is performed using the enhancement signal.
