(7) Electronic Soft Focus
This function is similar to an optical soft filter. By
subtracting the edge enhancement signal from the
original video signal, slight 'defocused' pictures are
created electronically. This is an important new
creative feature that can be used to either complement
or replace the Skin Tone Detail Correction function,
when more of a 'film look' is sought for close-ups, etc.
