3.4.2.7.12 Sequence AOI
On the "Sequence AOI" tab you do the settings for the sequence AOI mode of some DCx Cameras. In this mode
you can capture e.g. the same AOI with different parameter sets – exposure, gain, etc. (see Basics:
(AOI) ).

Note
The sequence AOI mode is only supported by DCC1240x and DCC3240x camera models.
Note that the sequence AOI mode cannot be used in combination with scaler, subsampling or binning.
In contrast to the Multi AOI
sensor readouts all AOIs sequentially and transfers the images as e.g. the same AOI is readout four times. The
frame rates are identical, but you can define different settings. For every AOI exposure time and master gain can
be set individually. For example you can capture the same AOI at first with a short exposure time and after this with
a long exposure time. An advantage of the sequence AOI mode is that you need no time for moves of the position
and it is not necessary to reprogram the AOI.
Beside the normal AOI (AOI 1) you can define up to three additional AOI 2-4. These additional AOI have the same
size as AOI 1, but you can set different parameters for:
Position of AOI
Exposure time
Gain
Readout cycles (number of images)
After you have defined an AOI, open the "Sequence AOI" tab. In the upper area you see the position and size of
AOI 1. In the area below you define the further AOIs.
Number of used AOIs
Here, you define the numbers of additional AOI. If you select further AOIs, the parameters of AOI 1 are copied for
