6.1.3 Readout Modes
The Kodak sensors, used in Baumer SXG cameras, are subdivided into four Taps.
Due to Baumer's integrated calibration technique, these taps are invisible within the re
-
corded images, but affect the operation and the rate of the readout process and therewith
the readout time (t
readout
).
Quad Mode
6.1.3.1
On quad readout mode all four taps are read out simultaneously as displayed in the sub
-
sequent figure.
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 Mode
6.1.3.2
On dual readout mode two taps (
Tap 1 + Tap 2 and Tap 3 +
Tap 4) 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 finished.
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
