5.12 Image Burst
The write pointer can be set to the start of the memory by sending a
ImageBurst_PortReset
command. Images can then be written again to the memory.
To read out the memory first start image acquisition and then send a
ImageBurst_StartReadMemory
command (or click on the button in PF_GEVPlayer). The images that
are read out are specified by the properties
ImageBurst_FirstImageNr
and
ImageBurst_NrOfImages
.
The memory can be read and written simultaneously. The user must synchronize reading and
writing, so that no memory location is written and read at the same time or that no image is
overwritten before it is read out. This is shown in the diagram in Fig. 5.39. Reading of the
memory can start after the writing of the first image has started. The time from the active
trigger edge to the start of writing is approx. the sum of the trigger delay, the exposure time
and the readout delay plus (see also timing diagrams in Section 5.1.7).
The images must be read with the same settings as they were written.
ImageBurst_FirstImageNr
and
ImageBurst_NrOfImages
must be set to values
that don’t result in reading beyond the end of the memory.
E.g.
if
ImageBurst_NrOfImagesMax
=21 and
ImageBurst_FirstImageNr
=5, then
Image-
Burst_NrOfImages
must be set to a value of 17 (=
ImageBurst_NrOfImagesMax
-
Im-
ageBurst_FirstImageNr
+ 1) or less.
The total number of bytes that are written to the camera RAM in image burst
mode must be a multiple of 16. This is enforced by the camera if no sensor
binning, horizontal binning or horizontal decimation is used. If any of these
modes are used then the user must ensure that this condition is satisfied. If this
condition is violated then the last few pixels (less than 16 pixels) of the last stored
image are not stored.
