<EM>> It's written "optical resolution : 600dpi x 1200dpi". So I should scan
|
|
</EM><BR>
|
|
<EM>> at 600 ?
|
|
</EM><BR>
|
|
<P>Yes. The "horizontal" resolution is typically determined by the CCD array
|
|
<BR>
|
|
(its density, and the optics that shine the image on it) and the vertical
|
|
<BR>
|
|
by the transport. For flatbed scanners, the "transport" is the bar. For
|
|
<BR>
|
|
page scanners, the transport is the feeder.
|
|
<BR>
|
|
<P>Of course this is not the case for area area devices, like digital cameras.
|
|
<BR>
|
|
These have an area of CCD sensors instead of the single row in a scanner.
