19. For Desired Memory Size , select the amount of contiguous
memory (in MB) that you want to allocate in your system to hold
the acquired frames. A 60 Hz, 640-by-480 image requires 308 KB
per frame; a 50 Hz, 768-by-576 image requires 443 KB per frame.
The actual amount of memory that the device driver can allocate
depends on your system resources. It is recommended that you
select only as much memory as you need to leave memory for
other devices. Once you enter the desired memory size, the
device driver allocates as much memory as possible to match the
value you entered; the actual memory size allocated is shown in
the
Actual Memory Size text box when you restart your system.
