Overlapped / pipelined transfer
By default, the steps exposure and readout out of an image sensor are
done one after the other.
• By design, CCD sensors support overlap capabilities also combined
with trigger (see figure).
• In contrast, so-called pipelined CMOS sensors only support the over-
lapped mode. Even less CMOS sensors support the overlapped
mode combined with trigger.
Please check the sensor summary (p. 61).
In overlapping mode, the exposure starts the exposure time earlier during
readout.
Note
In overlapped trigger mode, you have to keep in mind the follow-
ing formula
interval between two trigger events >=
(readout time - exposure time)
Pixels Picture element
PSE
Power sourcing equipment. The network PoE element that inserts
power onto an Ethernet cable.
Pseudo colors Display of gray scale images in false colors. A corresponding color is as-
signed to a specific gray scale value.
Resolution Number of pixels (horizontal x vertical)
ROI/AOI
Region/Area of interest.
SDK
Sofware development kit (SDK). The standard image processing
software library from MARTIX VISION is mvIMPACT.
