Controlling image capture

The following screenshot displays the sequence of commands needed to work

with deferred mode.

FastCapture

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. 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.

Note



This mode can be activated only in Format_7.

.................................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
