t. Monitor Controller PCB
In this block, the final image data (YMCBk) is converted into RGB data for display on the CRT.
The CRT output correction block corrects image data using the calibration data entered from the con-
trol panel. The calibration serves to bring the printing output and the display image (on the CRT) closer to
each other by varying the image density signals.
In the image editing block, the image (data) is rotated, shifted, or enlarged as specified on the control
panel.
The area image generation block generates image data for such items as an area frame to be displayed
on the CRT; the initial data and the post-edit data are integrated and displayed on the CRT.
Stores the coordinates nearest the start of the main scanning line where black changes to white.
