Rolling Shutter Global Clear Internal (Non-Overlap Mode)

Rolling Shutter Global Clear is an extended Rolling Shutter Mode available on Zyla 4.2 only. If enabled, the sensor rows are held in a global clear state to ensure there is no charge build-up on the sensor. When the camera is taken out of the Global Clear state, the exposure period begins for all rows in the sensor. When the required exposure period for Row 1 has completed, a signal frame rolling shutter readout phase begins. This means all rows have the same exposure start time but different exposure end times.

When the frame has been read out completely, the camera is returned to the Global Clear state until the user-defined cycle time is achieved or external trigger is detected (if in an external triggering mode).

Rolling Shutter Global Clear mode is best used in conjunction with illumination controlled by the Fire ALL signal.
