CHAPTER 2 FUNCTIONS & OPERATION
Since the data are processed as 8 bits within
the machine, they are converted from 10 bits to 8
bits at the Image acquisition unit. And, for
colored image data, RGB rearranging is
executed.

The QQ-Chip used in this machine is
designed to handle future multi-stream
processing. Image processors 1 and 2 for
conducting equivalent processing are provided
within the QQ-Chip. However, since the software
is not available for the earlier model, both
processors serve to conduct the processing of
image data. A multi-stream function can output
different modes of data from a single scan. The
description below describes the image
processing in the earlier model where the
mult-stream function is not available.
Image resolution conversion is carried out by
image processor 1. For converting resolution,
one of two methods, thinning-out and smoothing,
is used according to the image mode. The
smoothing process also helps to reduce moire
patterns.
The image data are stored in the SDRAM,
and accessed via the SDRAM_I/F (Interface).
Image processor 2 handles brightness
adjustment, contrast adjustment, and gamma
correction.
Image processor 3 handles edge emphasis,
simple binarizing, error diffusion, and automatic
brightness adjustment. The automatic brightness
adjustment is valid for simple binary mode.
In the JPEG module, the grayscale and color
data can be compressed. When JPEG is
selected, the image data size is reduced by
compression within this machine so that it can be
transferred to the personal computer in less time.
As a result, more documents can be scanned in a
given time.
Finally, processed image data are sent from
the DMA controller to the computer either through
the SCSI or USB interface.
Other image processing is carried out on the
personal computer.
