The Canon Still Video System stores images as analogue video recordings
so there is no digital version available. To get the images into a
machine you need a framegrabber. Don't know about other systems.

The Canon CLC500 can scan from slides and negatives. The CLC500 is mainly
marketed as a colour photocopier although it is described as an image
processing system. The CLC is really a colour scanner and printer hooked
together with an optional computer interface called an IPU -- Intelligent
Processing Unit). Canon sell an IPU that allows scanning and printing
via an IEEE-488 or SCSI port, Adobe have a colour PostScript IPU based
on the MIPS R3000. The Canon IPU's give you lots of control over the size
of the image you want to scan/print and let you do things like gamma
correction on the image inside the unit. The still video system can also
be connected to the IPU letting you grab images and print them, this
applies to both real video and the still video cameras. The CLC is
quite expensive (i.e. many tens thousands of dollars) but provides
quite useful functions. The quality of the scanner and printer is
good enough to use it to produce blow ups of slides and negs.
