FastCapture mode
By setting FastCapture 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 pos-
sible 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 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.
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.
