I could not find your specific model number on the Sony support site.
However, according the the Sony site Sony does not recommend Windows Vista
on the VGN line. The website says (I use another model in this line that is
listed),

"Sony does not recommend or support installation of the Windows Vista
Operating System with the VGN-A130 VAIO® computer."

"This decision is based on test results generated by installing and using
the Windows Vista operating system on a VGN-A130. These results did not meet
our standards for basic functionality and support. Therefore, Sony will not
release Windows Vista compatible drivers for this model."

Models in this line date from 2003.

Restore XP to the computer to use the feature you are seeking. The
manufacturer of the camera would not have written Vista drivers for the
device either.
