Non-Overlap Exposure; Overlap Exposure - HikRobot USB3.0 User Manual

7.4.1 Non-Overlap Exposure

After completing the current frame's exposure and readout, the next frame starts to expose and
read out. This process is called non-overlap exposure. The non-overlap exposure's frame period is
larger than the sum of the exposure time and the readout time, as shown below.

The camera will ignore the external signal in the readout section under this mode.

7.4.2 Overlap Exposure

Overlap exposure refers to the overlap between the current frame exposure and the previous
frame readout. In other words, when the previous frame starts to read out, the current frame
starts to expose simultaneously, as shown below.
