Abstract

The following invention is associated with a film scanner and other image capture devices. The invention is a software facility which informs the user whether a target DASD can accommodate an image file generated by the scanner. The invention will also provide an option for reserving that disk space prior to an image scan.

Image File Reservation Method

      The following invention is associated with a film scanner and
other image capture devices.  The invention is a software facility
which informs the user whether a target DASD can accommodate an image
file generated by the scanner.  The invention will also provide an
option for reserving that disk space prior to an image scan.

      The scanner is a device which digitizes film negatives or
slides.  This digitization process is a very slow yet precise process
which results in very high quality images.  The resolution of the
scan can be as fine as 2000 pixels by 3000 pixels.  At this
resolution, in color mode, the device produces 3 overlays; one of
red, one of green, and one of blue.  The resulting image file size
could require as much as 48 megabytes of storage.

      Many customer environments may use distributed image
processing.  This concept provides for remote image digitization and
for the remote execution of other image services on a Local Area
Network.  Typically, distributed systems are composed of several
low-powered inexpensive client workstations with one or more powerful
servers having large amounts of DASD.  With the possibility of large
image files being generated by the scanner, the server machine in
this environment would be an ideal place to store such a file.

      Scans could take as long as 20 minutes to complete.  If there
is not enough space on the target drive to house the entire image
file,...
