7.7.2 Rolling Shutter
Valid for
acA1280-60, acA1920-25, acA2500-14(*)
acA1300-60 and acA1600-60: Only valid if they are operated in the rolling shutter mode
(*) = Switchable shutter mode (see Table 16 on page 118)
The cameras are equipped with an electronic rolling shutter. The rolling shutter is used to control
the start and stop of sensor exposure. The rolling shutter used in these cameras has two operating
modes:
electronic rolling shutter mode (ERS mode) and
global reset release mode (GRR mode).
Electronic Rolling Shutter Mode (ERS Mode)
When the shutter is in the electronic rolling shutter operating mode, it exposes and reads out the
pixel lines with a temporal offset (designated as tRow) from one line to the next. When frame start
is triggered, the camera resets the top line of pixels of the AOI (line one) and begins exposing that
line. The camera resets line two tRow later and begins exposing the line. And so on until the bottom
line of pixels is reached (see Figure 62).
The exposure time is the same for all lines and is determined by the Exposure Time Abs parameter
setting.
