The user can select whether the input level is reverse or not by setting "LineInverter". For the MARS-G-P series camera, the default input line level is false when the camera is powered on, indicating that the input line level is not reversed.
  • Page 53 8.Features  Strobe In this mode the camera sends a trigger signal to activate the strobe. The strobe signal is active low. After receiving the trigger signal, the strobe signal level is pulled low, and the pull-low time is the sum of the exposure delay time and the exposure time.

  • Page 55 8.Features When the trigger mode is "FrameBurstStart", each time the camera receives a trigger signal, it will acquire multiple frames of image (the number of frames can be obtained by the function "AcquisitionFrameCount"). After receiving the trigger signal, the "AcquisitionTriggerWait" signal is pulled low and the camera starts the exposure transmission.

    8.Features 1) When the trigger mode is set to On, the trigger type is FrameStart After executing the AcquisitionStart command, the camera waits for a trigger signal, which may be a software trigger or a hardware trigger of the camera. Each time the camera receives a trigger signal, it can acquire a frame of image until the AcquisitionStop command is executed.

    8.Features 8.2.8. Set Exposure  Global Shutter The implementation process of global shutter is as shown in Figure 8-20, all the lines of the sensor are exposed at the same time, and then the sensor will read out the image date one by one. The advantage of the global shutter is that all the lines are exposed at the same time, and the images do not appear offset and distortion when capturing moving objects.
  • Page 66 8.Features The implementation process of electronic rolling shutter is as shown in Figure 8-21, different from the global shutter, electronic rolling shutter exposures from the first line, and starts the second line exposure after a row period. And so on, after N-1 line, the N line starts exposing. When the first line exposure ends, it begins to read out the data, and it need a row period time to read out one line (including the line blanking time).
