Re: Continuous digital panoramas (was Duel)

[Gerhard Bonnet <bonnet@xxxxxxxxxxx>]

As far as I know there are several companies announcing, and/or "really"
selling scanning digital panoramic cameras. 

Dr.Clauß	www.dr-clauss.de
e-pan		www.e-pan.com
EyeScan	www.kst-dresden.de
Innotech	www.innotech-ht.com
PanoScan	www.panoscan.com
Seitz		www.roundshot.ch
SpheronVR	www.spheron.com

The cameras (solution) differ in many aspects such as resolution,
sensitivity, contrast ratio, noise, color depth, color reproduction quality
/ ICC-support, effective scanning speed, price, cabling, interfacing,
portability, lens manufacturers supported, mechanical vibration, size,
weight, battery operation time, capability of doing spherical panos,
integrated post processing tools, ease of overall workflow ....

When talking about transmission speed, the scanning cameras do not really
suffer from that, as the camera can buffer the image data and/or use
suitable interfaces like SCSI/USB1.1/FireWire or the forthcoming USB2.0.
Instead - in many situations we find that the image scanning time is
"exposure time limited" and dominated by the exposure time per scanline
times the number of scanlines of the image. Examining the reason for this,
you find that it's both the original CCD sensor sensitivity and the quality
of the analog electronics used. There are very BIG differences which can
easily be spotted when comparing the systems.
