The make-up control circuit edits the image using
the above logic circuit.
The modulated image data, the outline image data, the background pattern data and the
designated area data are processed simultaneously in the make-up control board.
One input of the selector (DO - D13) is output at CNOOI -18 as the M-DATA 2 signal. The
data selection depends on which make-up function the user selects. The above selec-
tion table shows the relationship between the make-up function and the M-DATA 2 out-
put.
