Description of the data path
FastCapture mode
By setting
FastCapture
to
false
, the maximum frame rate both for image acqui-
sition 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. The speed of the image transport over the 1394 bus
can be defined via the
BytesPerPacket
register. This mode is ideal for applica-
tions 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.
Similar to the HoldImg mode, captured images will be stored in the internal
image FIFO, if the transport over the 1394 bus is slower than images are cap-
tured.
Note
This mode can be activated only in Format_7.
