Hello Eric!
Thanks for your sugestionsa and reply.
Please see my coments bellow.
A large amount of the time needed to do the
Snap is independent of the speed of the computer. Some things that
might affect it (off the top of my head):
a) Camera firmware - different versions often have vastly different timing for writing to certain registers
Danilo: I use same cameras on both computers and same firmware on cameras, so that can't be the cause.
b)
Camera settings - some registers for some settings might have vastly
different timings. Can you compare the camera settings stored in the
ICD file for the two systems?
Danilo: I have done that and they are exactly the same in ICD file and also then in my aplication.
c) Firewire card chipset -
Configuration requires lots of register I/O operations that must be
submitted to the firewire card and then completed. The implementation
of those writes and the latency involved might be highly dependent on
the chipset used, along with things like your system's bus topology
(PCI express has a much higher latency for register operations compared
to PCI, for instance)
Danilo: I use PCI EXPRESS card firewire host card.
d) Time taken to acquire the image - The
total time for Snap is including the time to expose the image sensor
and transfer the image. Are you sure you have the cameras configured
for the same exposure time, frame rate, and transfer settings (bus
speed, packet size, etc)?
Danilo: This is good question. All general setings regarding exposure time... are same. I'm not sure about bus speed, packet size,... Setings in ICD file are correct.
Regards!
