6.1.2. Shutter
All cameras of the SX series are equipped with a global shutter.
Pixel
Active Area (Photodiode)
Storage Area
Microlens
Global shutter means that all pixels of the sensor are reset and afterwards exposed for a  specied interval (t
exposure
). 
For  each  pixel  an  adjacent  storage  area  exists.  Once  the  exposure time elapsed, the information  of  a  pixel  is  transferred  immediately  to  its  storage  area  and  read  out  from 
there.
Due to the fact that photosensitive surface gets "lost" by the implementation of the storage  area, the pixels are mostly equipped with microlenses, which focus the light to the pixels 
active area.

6.1.3. Readout Modes
The Truesense Imaging sensors, employed in Baumer SXC cameras, are subdivided into 
four Taps.
Due to  Baumer's integrated calibration  technique, these taps are invisible within the re­corded images, but affect the operation and the rate of the readout process and therewith the readout time (t
readout
).
Quad Mode6.1.3.1.
On quad readout mode all four taps are read out simultaneously as displayed in the sub­sequent gure.
The data of all pixels of one tap are moved to the output register and afterwards trans-
fered to the memory.
Once the information have left the output register, the readout is done. 
This mode provides the full potential of the sensor and leads to the maximum frame rate.
Dual Mode6.1.3.2.
On  dual  readout  mode  two  taps  (Tap 0 + Tap 2 and Tap 1 + Tap  3)  are  combined. 
The data of all pixels of one tap are moved to the output register and afterwards trans-
fered to the memory.
Once the information have left the output register, the readout is nished. 
Due to the fact, that more data needs to be read out, the t
readout
is increased compared to
the quad readout mode.
It is considered:     t
readout(Dual Mode)
 ≈ 2 × t
readout(Quad Mode)

Single Mode6.1.3.3.
In single readout mode all taps are combined as displayed in the subsequent gure.
The data of all pixels of the sensor are moved to the output register and afterwards trans-
fered to the memory.
Once the information have left the output register, the readout is done. 
Due to the fact, that the complete sensor needs to be read out, the readout time t
readout
is
increased compared to quad and dual readout mode.
It is considered:     t
readout(Single Mode)
 ≈ 4 × t
readout(Quad Mode)

Timings6.2.
The image acquisition consists of two seperate, successively processed components.
Exposing the pixels on the photosensitive surface of the sensor is only the rst part of the  image acquisition. After completion of the rst step, the pixels are read out.
Thereby the exposure time (t
exposure
) can be adjusted by the user, however, the time need-
ed for the readout (t
readout
) is given by the particular sensor and image format.
Baumer  cameras  can  be  operated  with  two  modes,  the  Free Running Mode and the
Trigger Mode.
The cameras can be operated non-overlapped
*)
or overlapped. Depending on the mode
used, and the combination of exposure and readout time:
Non-overlapped Operation Overlapped Operation
Here the time intervals are long enough to process exposure and readout succes-
sively.
In this operation the exposure of a frame
(n+1) takes place during the readout of  frame (n).

6.2.1. Free Running Mode
In the "Free Running" mode the camera records images permanently and sends them to 
the PC. In order to achieve an optimal (with regard to the adjusted exposure time t
exposure
and image format) the camera is operated overlapped.
In case of exposure times equal to / less than the readout time (t
exposure
 ≤ t
readout
), the maxi­mum frame rate is provided for the image format used. For longer exposure times the frame rate of the camera is reduced.

6.2.2. Trigger Mode
After a  specied external event (trigger) has occurred, image acquisition  is started. De­pending on the interval of triggers used, the camera operates non-overlapped or over­lapped in this mode.
With regard to timings in the trigger mode, the following basic formulas need to be taken
into consideration:
Case Formula

(1) t

= t

(2) t

t

(3) t
earliestpossibletrigger(n+1)
= t

(4) t
notready(n+1)
= t
exposure(n)
6.2.2.1. Overlapped Operation: t
exposure(n+2)
= t
exposure(n+1)
In overlapped operation attention should be paid to the time interval where the camera is unable to process occuring trigger signals (t
notready
). This interval is situated between two 
exposures. When this process time t
notready
has elapsed, the camera is able to react to
external events again.
After t
notready
 has elapsed, the timing of (E) depends on the readout time of the current im-
age (t
readout(n)
) and exposure time of the next image (t
exposure(n+1)
). It can be determined by the 
formulas mentioned above (no. 1 or 3, as is the case).
In case of identical exposure times, t
notready
remains the same from acquisition to acquisi-
tion.

If the exposure time (t

tion, the time the camera is unable to process occuring trigger signals (t

) is scaled
