9.7.2 FastCapture
This mode can be activated only in Format_7.
When FastCapture is set to “false”, the maximum frame rate both for image acquisition and read
out is associated with the packet size set in the BYTE_PER_PACKET register. The lower this value
is, the lower the attainable frame rate is.
By setting FastCapture to “true“, all images are recorded at the highest possible frame rate, i.e.
the setting above does not affect the frame rate for the image intake but only the read out. This
mode is ideal for applications where a burst of images need to be recorded at the highest sensor
speed but the output can be at a lower frame frequency to save bandwidth.
……………………….Stop continuous mode of camera
…………………….Check pres. of deferred mode and FiFo size (Dh= 13 fr.)
…………………….Switch deferred mode on
…………………….Do first One_shot
…………………….Do second One_shot
…………………….Check that two images are in FiFo
…………………….Read out the first image of FiFo
…………………….Check how many images are left in FiFo
…………………….Read out the second image of FiFo
……………………….Check how many images are left in FiFo
