IMAGE PROCESSING

2.4 IMAGE PROCESSING

2.4.1 OVERVIEW

VRS

Board

The CCD generates two analog video signals. The SBU (Sensor Board Unit)

converts these analog signals to 8-bit digital signals, then it sends these digital

signals to the SCU (Scanner Control Unit) board through the IOB board. The IPU

(Image Processing Unit) IC on the SCU does the image processing, then the image

data goes to the computer through the Memory Control IC and the SCSI controller.

The CIS (Contact Image Sensor) unit in the duplex for reverse-side scanning

outputs two digital signals. The IPU on the ERCU (Reverse Control Unit) board

does the image processing, then the image data goes to the VRS Board through

the SCU.
