The idea of this document is to explain some basic principles of scanning
|
|
hardware and software. It's not related to any specific scanners nor to
|
|
any specific scanning software.

<h2>Hardware (or: what is inside the scanner?)</h2>
|
|
<h3>Sensor types</h3>
|
|
<h4>CCD</h4>
|
|
<h4>CIS</h4>
|
|
<h3>Analog frontend (AFE)</h3>
|
|
<h3>Interface chips</h3>
|
|
<h3>Stepper motor</h3>
|
|
<h3>Calibration area</h3>
|
|
|
|
<h2>Software (or: how does this thing work?)</h2>
|
|
<p>
|
|
Keep in mind that some of the steps mentioned here can be done by the
|
|
scanner itsself (its firmware) without engagement of the driver.
|
|

|
|
<h3>Calibration</h3>
|
|
<h3>Line-distance correction</h3>
|
|
<h3>Interpolation</h3>
|
|
<h3>Gamma correction</h3>
