Edge enhancement
In the high frequency range of the signal required for
image sharpness, there are often small amplitude
components, and simple enhancement would also
increase the noise component (high frequency small
amplitude components).
Use the CRISP and DEPEND knobs to set an
appropriate range, then adjust the sharpness with the
DETAIL GAIN knob.
