6.2.5 Picture Quality Control Circuit
This circuit consists of a recording picture control standard cell IC40 (DZZAC000097 or “FLIC”), an
interpolation table ROM (IC41), line memory for interpolating (FIFO Memory) and its peripheral circuitry.
The recording picture control standard cell (IC40) inputs the serial data from the IC20 (DZZAC000096) or
MBCP, conducts picture quality correction (smoothing), reduction, synchronization control, etc., then sends
this data to the printer. These functions are as follows:
Picture quality correction circuit (smoothing)
Compares the picture element with 15 surrounding picture elements, determines the interpolation data from
the interpolation data ROM, and smooths out diagonal lines, etc., on the recorded picture.
Image range isolation circuit
Identifies the halftone picture range and controls smoothing to eliminate blotching of the recording picture
which has undergone error diffusion or other processing.
Reduction circuit
This circuit is used to process the received data so that it fits on the recording paper, according to the Fax
Parameter settings.
Synchronization control circuit
This circuit is used to synchronize the output recorded data with the horizontal synchronizing output signal
from the printer for each line. Within a line, it is synchronized with the dot clock signal. The dot clock signal
is provided by dividing the crystal oscillator frequency from the Extend Generator Circuit (32 MHz) by 5.
