As this system has huge memory(320MB!), 30 second video sequence can be captured on the memory X-) then into disk (what a big buffer it is!). Thus, it is said that fps value in the table roughly indicates the rate from galileo video to memory.

Quarity Number at JPEG modes means Q-Factor. 'High' mode captures every scan line in the image while 'low' mode captures every even line (field) and replicates the data to generate the right sized image.
