response to a 1-line synchronous signal. In the video block, image processing is performed for printing and the resultant data is transferred to the LED head.

(7) PC Scanner

The analog data output from the image sensor is input to the MCNT-PCB to be amplified by the amplifier. The amplified analog data is input to the scanner

controller. Next, the analog data is converted to digital data by the built-in A/D converter. The digital data is corrected by the internal correction function,

transferring binary-coded data to the IOGA5 every eighth pixel. The data input to the IOGA5 is temporarily written into the external DRAM (4 megabits x 16 bits).

The written data is compressed to TIF data by firmware, then written into the external DRAM again. The written TIF data is sent to the MCNT's parallel I/F through

the IOGA5.
