2.6.2.3 Rolling Shutter Internal Triggering (Non-Overlap Mode)
InternalTriggerModeallowstheusertocongureanexposuretimeandcycletime.ForInternalTriggering
Non-overlap mode, the exact acquisition sequence depends on the exposure time and cycle time set as shown
in Figure 16. The following diagrams show the behaviour of TTL outputs ‘Fire’, Fire n’, ‘Fire ALL’ and ‘Fire ANY’.
Fire ALL indicates the time period within a frame during which all rows are exposing simultaneously.
Fire ANY indicates the time period within a frame during which any row is exposing
Initially, the entire sensor is held in a global clear state to ensure that there is no charge build-up on the sensor.
Global Clear goes LOW and a frame read out is initiated. This frame is discarded as it does not contain the
correctexposureperiod.Readingoutaframeeectivelybeginsanewexposure.Whentheexposureperiod
has completed, a signal frame read out phase begins. When the frame has been read out completely, the
GlobalClearisheldHIGHuntiltheuser-denedcycletimeisachieved.
