Overlapping Exposure with Sensor Readout

The frame acquisition process on the camera includes two distinct parts. The first part is the exposure of the
pixels in the imaging sensor. Once exposure is complete, the second part of the process – readout of the pixel
values from the sensor – takes place. In regard to this frame acquisition process, there are two common ways
for the camera to operate: with Trigger Overlap – Off and with Trigger Overlap - Readout.
In the Trigger Overlap – Off mode of operation, each time a frame is acquired the camera completes the entire
exposure/readout process before acquisition of the next frame is started. The exposure for a new frame does not
overlap the sensor readout for the previous frame. Figure 8.7 illustrates the Trigger Overlap parameter set to
Off and the Exposure Mode parameter set to Trigger Width.
