Image Acquisition Control AW00089317000
122 Basler ace GigE
The cameras can provide an exposure active output signal that will go high when the exposure time
for line one begins and will go low when the exposure time for line one ends.
If the camera is operating with the rolling shutter in ERS mode and you are using the camera to
capture images of moving objects, the use of flash lighting is most strongly recommended. The
camera supplies a flash window output signal to facilitate the use of flash lighting.
For more information about
the exposure active output signal, see Section 7.10.1 on page 135.
the Exposure Time Abs parameter, see Section 7.6 on page 115.
the flash window, see Section 7.7.2.1 on page 125.
Global Reset Release Mode (GRR)
In the global reset release mode, all of the lines in the sensor reset and begin exposing when frame
start is triggered. There is a temporal offset (designated as tRow) from one line to the next in the
end of exposure. The exposure time
for line one is determined by the Exposure Time Abs parameter setting.
for line two will end tRow after the exposure ends for line one.
for line three will end tRow after the exposure ends for line two.
And so on until the bottom line of pixels is reached (see Figure 63).
The pixel values for each line are read out at the end of exposure time for the line. The readout time
for each line is also equal to tRow (see Table 18).
