The CRT output correction block corrects image data using the calibration data entered from the control
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.
